Background: The extent to which behavior-analytic interventions are offered to Indigenous populations across CANZUS in accessible and culturally appropriate ways is unknown. We conducted a scoping review with a thematic analysis of the extant literature to find: (1) what are the barriers and facilitators for providing effective and equitable delivery of psychological services (with a behavioral component) to Indigenous populations; and (2) what tools and practices exist for an effective and equitable service delivery.
Methods: We systematically reviewed Medline, CINAHL, PubMed, PsycInfo, Web of science, Ovid and INNZ databases between 1990 and 2020. For the scoping review, we adhered to the JBI methodological approach (2015) and the PRISMA strategy for the identification, selection, and appraisal of the reviewed articles. A total of 1265 unique articles met the criteria for the screening by title; 238 by abstract; 57 were included for full text assessment; and 37 were included in the final analysis.
Results: Three themes were revealed to account for the barriers and facilitators of culturally friendly practices: (1) connecting practices are about interactions shaping the relationship between service provider and service client; (2) innovative practices test new approaches and innovations that could facilitate access to psychological services and overcome barriers, and (3) reflective practices are about critically examining the processes and actions undertaken toward effective cultural adaptation of services.
Conclusions: Our analysis suggests that the level of success in bringing together services and the recipients of treatment (connection), showing flexibility and persistence in finding solutions (innovation) and examining the role of our behaviors in reaching our goals (reflection) is determined by the providers' action in the aforementioned three dimensions of practice.
Introduction
Applied Behavior Analysis (ABA) is a scientific approach to improving socially important behaviors by the systematic application of the psychological principles of learning theory. Many of its applications are supported by a vast scientific evidence base. Though ABA-based interventions are most widely recognized as effective for improving developmental outcomes in individuals with autism spectrum disorder (ASD) (1), it has many other applications, including in healthcare, general education, gerontology, and business (2). Recently, the field of applied behavior analysis (ABA) has acknowledged its implementation of otherwise effective behavioral principles for behavior change as largely non-contextualized (3). However, behavior occurs in an environment (including culture); therefore, meaningful, lasting change in behavior occurs when the various environmental contingencies (including culture) impacting on behavior are accounted for and factored into a program of change.
The role of culture in shaping behavior has long been recognized in the field. For instance, Skinner characterized culture as a variable with multiple controls on behavior (4). ABA interventions are deeply rooted in a Western cultural context (5), and it appears that there is an established, one-sided standard of practice that disregards non-Western cultural variables as unnecessary to consider (6). A recent review of cultural adaptations to telehealth services revealed that most behavior analysts are challenged by the lack of relevant literature on specific cultural adaptations in relation to outcomes.
Indeed to date, no single study has explicitly evaluated or compared cultural adaptations for ABA-based interventions (7). Beaulieu, Addington and Almeida published a survey of behavior analysts that revealed that only 57% of behavior analysts work with diverse populations in the US (8). Further, they were reported to have little or no training in working with clients who present with marked cultural differences. The importance of culture in understanding social behavior—be it adaptive or maladaptive—is not a new issue in ABA (9, 10). The fact that behavior analysts fail to include cultural variables of behavior in explaining the social contingencies that control behavior may result in systematically overlooking the broader social context when designing and negotiating interventions. Arguably, the emphasis on essential learning principles, operationalizing observable behavior, empirical measurement, and adherence to laboratory-level standards of inquiry means that much nuance is removed from the understanding of behavior in ABA research and, in turn, practice. Given the call for cultural adaptations of ABA practice (11–13), this review is focused on the literature investigating barriers and facilitators for any psychological service that aims at behavior change.
Indigenous populations in Canada, Australia, New Zealand, and the United States (the CANZUS nations) are faced with unique challenges when it comes to effective and equitable delivery of services. The World Health Organization (WHO) defines equity in health as a process of minimizing factors of disparity—including, but not limited to, health care—between those from different social backgrounds (14). Many Indigenous peoples across CANZUS are over-represented with the burdens of sub-standard housing, poor education, unemployment, low income, cultural alienation, and other factors that contribute to the problem of health disparities. A recent review of the assessment of mental health services use by Indigenous populations across the CANZUS nations reported that only half of the surveys in their review had asked questions relating to interventions received and possible barriers to care (15). Their outcomes illustrate the fact that measuring service use by Indigenous populations has not been systematic and has not included indicators of the quality of the care delivered. The quality of services to Māori has recently been the focus of the New Zealand Health and Quality and Safety Commission, as inequity does not exist in access to services alone (16). For instance, people in New Zealand who live in socioeconomically deprived areas were 2.1 times more likely to experience psychological distress than other people living in less deprived areas. Māori (the Indigenous people of New Zealand) in particular fall behind non-Māori across all socioeconomic indicators, and they mostly live in under-resourced neighborhoods (14). Among other things, deprivation is a very serious barrier for those who need crucial services (17).
These observations are not explained by cultural difference per se. Many indigenous populations are uniquely disadvantaged as they find themselves in an involuntary culture contact situation as a result of having been colonized. When people from different cultures meet, various within- and between-group processes affect the developmental course of individuals and groups and their behavioral adaptations during the process of acculturation. Theories of acculturation (18–20) describe how involuntary culture contact situations can lead to maladaptive outcomes for minority groups and individuals, such as rejecting the values and practices of the mainstream culture, and thereby the keys to success within those cultures (21). Good outcomes of acculturation are promoted by positive attitudes toward both: one's own culture and the mainstream culture. It is therefore important to value and respect the cultures of individuals and to be able to work effectively with individuals who may have developed negative attitudes to the mainstream culture.
Though much has been written about the problems ethnic minorities have faced since the 1980s [e.g., (22)], only in the last decade newly published papers in North America have begun to inform clinicians on cultural adaptation, mainly for cognitive-behavioral therapy (CBT), whereas this matter has barely been investigated in other countries (23). For example, CBT has been adapted to treat refugees and ethnic minorities with anxiety or depression in the US, but cultural adaptation is still lacking for other psychological disorders (24). Evidence on the effectiveness of cultural adaptations is mixed and suggests that particular cultural adaptations may be beneficial for specific subgroups but not for others (25). A review of cultural adaptations for depression in minority ethnics highlighted that not all studies reported on what adaptations had been made; and the studies that did report this, were focused on the implementation of procedures rather than on the context of treatments (26). Moreover, a recent review of interventions for schizophrenia concluded that context, intervention, and design seem to influence the efficacy of cultural adaptations; however, adaptted interventions have not been compared to unadapted interventions (27). Nevertheless, cultural adaptations seem important if we are to promote acceptance of psychological interventions as a pre-requisite for effective and equitable delivery of services for those in need. Efforts to account for culture in interventions are a recent development (28), and cultural-behavioral systems scientists are increasingly contributing to a better understanding of the interaction between complex systems such as socioeconomic factors (29). In New Zealand, Te Tiriti o Waitangi puts an ongoing obligation on the Crown for partnership, participation and protection of Māori. As proposed in Plessas, McCormack and Kafantaris “for behavior analysts to achieve better outcomes, better accessibility and better choices of interventions for Māori, there is a need to develop skills that reflect cultural practices” [(30), p. 865].
This review aims to uncover and explore themes related to factors that impede or facilitate access to and participation in psychological services, as well as tools and practices to inform effective and equitable delivery of psychological services for Indigenous populations and in particular Māori. It is recognized that Indigenous peoples worldwide share common experiences of colonization and marginalization. In this paper, we focus on the issues for Māori, the “people of the land” (Tangata whenua), i.e., the Indigenous people of New Zealand, though we expanded our literature search to other Indigenous populations. In combination with considering the health system's obligations based on Te Tiriti o Waitangi, the results of this review will inform a survey methodology and will determine what questions a future survey should be asking. This scoping review aims to find answers to two main questions: (1) What are the barriers and facilitators for access to effective and equitable psychological services (with a behavioral component) for Indigenous populations? (2) What tools and practices exist in psychology (with a behavioral component) for an effective, culturally sensitive and equitable service delivery for Indigenous populations?
Method
A systematic search was conducted to identify key themes in the literature regarding effective and equitable delivery of services to Indigenous populations –in particular, Māori– that may facilitate access and culturally appropriate service delivery.
The first step in the review process was the development of a study protocol by the first author that was reviewed by the research team, based on the guidelines provided by Joanna Briggs Institute Reviewers Manual on scoping review methodology (31). Following the guidelines, we defined from the outset our research questions, inclusion/exclusion criteria, search strategy and the study selection process for data extraction.
To answer our specific research questions, we conducted a scoping review with a reflective thematic analysis. We were particularly interested in finding out more about the accessibility and effectiveness of treatments specifically within behavior-analytic services, for indigenous populations, but it was not possible to identify such a narrow scope; therefore, we broadened our focus to extract data from all psychological services that target at least one behavior component for change. We included peer-reviewed studies and gray literature specifically for Māori. studies published from 1990 on. During the 90s, policies with a specific focus on improving Māori health were developed in New Zealand (32). Other CANZUS countries followed a similar trend regarding Indigenous cultures during that time; a search investigation showed that studies discussing cultural concerns started to be published around that time.
Our search strategy was comprised of four steps The first author developed keywords (see Figure 1) and trained the second author to conduct the initial search with an expert librarian's support in psychological literature searches (Step 1). Six international databases (Medline, CINAHL, PubMed, PsycInfo, Web of science, Ovid), as well as the Index New Zealand (INNZ) database and all New Zealand journals, were searched between 1990 and 2020, and 1265 references were identified after duplicates were removed. We then carried on searching gray literature and the NZ Ministry of Health websites for government publications (Step 2). Twenty-four more articles were identified as relevant to our research question. After excluding all duplicates, using the bibliographic citation management software Endnote, we performed a manual check. This resulted in 1265 articles, which were screened by title (Step 3). Of these 785 were excluded as irrelevant to our questions, and further 285 were removed as they referred to non-Indigenous populations. The remaining 238 articles were reviewed by title and abstract (Step 4).
Figure 1. Search strategy.
Our inclusion criteria were: (a) studies from CANZUS nations (Canada, Australia, New Zealand and the United States), (b) targeting Indigenous populations and reporting them as “disadvantaged” or “deprived” or studies targeting Māori (and Pasifika) regardless of socioeconomic status, (c) studies evaluating the accessibility and effectiveness of psychological interventions, or papers investigating tools and practices to facilitate culturally appropriate psychological service delivery or ways to improve services, (d) any study type (except prevalence and letters to editors) including discussion, evaluations, and reviews. We only included peer-reviewed literature, except for literature specifically related to psychological interventions or services for Māori.
The exclusion criteria were set as follows: (a) topics related to Organizational, Forensic or Health Psychology, (b) studies on sexual or physical education, criminal behavior, addictions, disease prevention, (c) studies on the participants' perceptions or feelings about health care providers per se, (d) studies related to health behavior (e.g., diabetes, contraception, etc.), (e) studies that discuss scale measures (i.e., validations), (f) studies that analyze cultural concept definitions (such as cultural competence or diversity) and (g) studies on ethnic minorities or social minority groups (e.g., LGBTQI+).
Our search was completed in March 2020, and an alert was set to notify the authors of any new studies meeting our search criteria that might be published until the end of 2020.
Both types of screenings, first by title and then by title and abstract, were conducted by three reviewers (AP, MB, JM). One of the reviewers was an Indigenous woman, while the other two reviewers were non-Indigenous. When titles only were screened, 25% (~300 articles) were reviewed independently by the second reviewer. Any time the reviewers were not certain, then the title was reviewed by at least two reviewers. Had any disagreements not been resolved between the first and second reviewers, an independent third reviewer (AA) would have determined the final inclusion. 51 articles from the research literature, and a further six articles from gray literature (=total 57 articles) met criteria for full article review. The first author conducted the full review, and ten articles were blind-screened by another author (JM). The full review led to the exclusion of the gray literature, except one, and 15 discussion and review articles. As a result, a total of 37 studies were included in the analysis. See Figure 2 for a flow chart of the PRISMA search strategy.
Figure 2. A PRISMA flow diagram showing the steps for the scoping review.
The data extracted were: Title, Authors, Year, Journal, Study type, Country, Service Type, Barriers and Facilitators, Tools and Practices, and suggestions for service provider training. The extracted data were analyzed through a reflective thematic analysis procedure using a theory-driven approach. The reflective thematic analysis procedure was conducted in an inductive way through six phases: (a) the first author familiarized herself with the data and highlighted and made notes on any text that was directly answering the two research questions, and (b) generated semantic (descriptive) codes from the extracted information to (c) construct themes; at first, (d) preliminary themes were constructed by the codes and were tested with JM and reviewed by all authors. Lastly, (e) the final definitions and themes were generated by telling a story of the data and (f) producing the results (33). Our research questions were guiding the analysis and we treated all the extracted information as a whole dataset. The approach used acknowledges that we are not separated from the data (34) and that the knowledge derived can be influenced by the diverse cultural backgrounds represented in our team and by our having different work experiences, including clinical and non-clinical experience. Our multinational team based in New Zealand includes professionals with a wide range of experiences in behavior analysis (e.g., education, mental health, mindfulness) and in other areas of psychology (i.e., clinical). The team is committed to contribute their fair share to the research into cultural adaptation to psychological practice. The composition of our team created a unique blend of perspectives on data and understanding of the patterns the data produced.
Results
Scoping Review Results
Table 1 summarizes the characteristics of the studies included in this review and Table 2 provides an enumeration and brief description of the details of each study. Ten of the 37 studies included an evaluation of a specific intervention regarding the cultural adaptations made during training; all studies described some sort of barriers and facilitators of psychological services (see Table 1 for an overview of the study characteristics). Most intervention studies involved parent training programs (Studies 1, 7, 16, 18, 29, 33, 37) and cognitive-behavioral therapy (Studies 2-5, 17, 22), though several others were based on cognitive-behavioral principles. Only one paper employed single-case research methods to assess the behavioral impact of an intervention (6). The remaining studies employed mainly qualitative methods save two studies that used quantitative methods (Studies 14-16). Several Indigenous populations were included: First American Indians/Alaska Natives (Studies 5-6, 8-10, 12, 15, 18-19, 25-26, 31, 35), followed by Māori (Studies 2-3, 7, 11, 14, 16, 21-22, 27-28, 32), followed by Aboriginal and Torres Islanders (Studies 1, 4, 13, 17, 29, 33, 36, 37). A few studies included Aboriginal Canadians and First Nations (Studies 11, 20, 23-24), one study included Pasifika (Study 34), and another one Inupiat Eskimo (Study 30). Fourteen studies were from the USA (Study 5-6, 8-10, 12, 15, 18-19, 25-26, 30-31, 35), 11 were from New Zealand (Study 2-3, 7, 14, 16, 21-22, 27-28, 32, 34), eight from Australia (Study 1, 4, 13, 17, 29, 33, 36-37) and four from Canada (Study 11, 20, 23-24).

Thematic Analysis
The information was categorized according to our research questions into three main areas: (1) barriers related to overall implementation issues of psychological interventions for Indigenous populations and, in particular, to the accessibility of services; (2) factors/variables that facilitate cultural adaptations during the discussion or implementation of interventions; and (3) suggestions on specific tools and practices, or service provider training recommendations, that have been introduced or discussed as possible steps for improvement. We generated three overarching themes to account for the barriers and facilitators of cultural practices. Each theme revolved around a central organizing concept (see Figure 3) that provided a description of the theme data: (1) connecting practices are about interactions shaping the relationship between service provider and service client; (2) innovative practices test new approaches that could facilitate access to psychological services and remove barriers, and (3) reflective practices are about critically examining the processes and actions undertaken toward effective cultural adaptation of services. These themes are distinct in the way the barriers and facilitators are approached but can overlap in regard to variables/factors. For example, under “innovative practices,” a barrier factor may be approached by testing novel strategies through trial and error aiming at removing the barrier, while under “reflective practices” the same barrier can be approached critically by investigating actions that have contributed to it. At the same time, and in spite of the barrier, “connecting practices” may support an ongoing relationship between service and client. Table 3 summarizes the subthemes related to the overarching themes.

Table 3. Summary of themes and subthemes that emerged from thematic analysis.
Connecting Practices
Connecting practices are defined as any action that can move clients and service providers closer or apart depending on the action taken by the treatment provider or the treatment recipient. The results suggest that the ability or inability to create a relationship from the start, and to sustain this throughout the time of service provision is crucial. Clients often come in with a sense of guarded anticipation, or experiences of insecure relationships, or a lack of comfort or partnership. Action needs to be taken to build relationships. For example, the literature reports issues regarding confidentiality, distrust on the part of diverse populations, or partial disclosure of what may be the referral problem (as in Study 7). However, if professionals make sure effective communication is in place, build working relationships with elders in the community, even participate in Indigenous ceremonies, then by getting to know each other, relationship-building hurdles can be overcome.
The level of engagement may interfere with the relationship, even before accessing the service. For example, studies report that those in need for intervention do not always initiate help-seeking behaviors or may show an unwillingness to use the service (Study 15). However, outcomes can be promising when one involves those promoting engagement at all stages of the treatment (e.g., peer counselors, family intervenors or other indigenous specialized roles) or when action is taken toward that direction by including the whole family and providing community support. For connecting practices, we also included the level of congruence between western worldviews (expectations, values, etc.) and actions taken to include indigenous knowledge in the design and implementation of treatments by having an indigenous methodology in the treatment plan or by integrating alternative treatments.
Further, the literature indicates that it is also critical to consider the level of collaborations at all stages of a treatment or a research project (e.g., consent vs. compulsory treatment) with actions taken toward working jointly to achieve a culturally fit intervention. An example of a positive collaboration is funding to incorporate indigenous practices by paying for traditional practitioners for their service (Study 10) and aligning this involvement with evidence-based practice (Study 35). Lastly, an essential element to connecting practices is the sense of ownership, meaning that the practitioner shares a similar culture with the client and is a local presence in the community. This for example can be achieved by taking actions that minimize disparities between indigenous and non-indigenous individuals involved in the treatment (as in Study 37).
Innovative Practices
Innovative practices are defined as the level of flexibility shown to fit interventions or training programs to cultural practices by adapting them and developing creative training opportunities. Innovative practices need to consider how interventions are adapted to fit indigenous populations' needs in a cultural context and the number of practical solutions provided based on the best available current research. For example, the literature reports that interventions often fail to take into account indigenous behaviors that affect engagement in the intervention. At the same time, the evidence suggests that culture-tailored interventions should not be regarded as a one-size-fit-all treatment (as in Study 11); however, more often than not, interventions are not culture-responsive, as there is a lack of literature on cultural adaptations (as in Study 22) or behavioral measurements of adaptation (as in Study 26). It seems reasonable to consider a shift to practice-based evidence and use more detailed reports on the individual client's demographics when applying an intervention. The tools used either during the assessment or the implementation phase are part of the process; they can facilitate cultural acceptance and inclusion of factors that promote positive treatment outcomes, such as the conceptualization of a problem behavior in its cultural context. Resources that enable cultural acknowledgment, by adapting traditional names for core concepts for example, can be beneficial too.
Any education that promotes cultural practices on any level is critical to psychology practices. A few examples from the literature are to conduct workshops that target sharing knowledge (mutual-way mentoring) (Study 33), to provide education to policymakers (as in Study 27), to train providers in adapting educational curricula to develop cultural practice skills of diverse backgrounds (Study 36), to teach alternative theoretical models (i.e., indigenous thinking) and cultures across university departments (e.g., Study 28). These suggestions are accompanied by innovative teaching strategies that depart from standard methods of teaching cultural practices, not to mention the recruitment and training of diverse populations for the future workforce. Even after graduation, ongoing work is necessary, with cultural advisors, peer support and mentoring being regarded as tools to keep service providers aligned with culturally adapted practices.
Reflective Practices
Reflective practices are about critically examining positive and negative behaviors in the diverse therapeutic relationship, as well as the processes and actions undertaken toward effective cultural adaptation of services. The literature reports that treatment may not be accessible due to barriers related to practical difficulties (as in Study 1), such as traveling to the appointment site or adhering to treatment (e.g., transportation, childcare assistance, other social determinants of health); when the aim is to provide accessible services, such knowledge needs to be critically reflected upon. Moreover, one has to be aware of clients' negative anticipations regarding the outcome of treatment based on their personal experiences or views on mental health, such as their beliefs about the diagnosis, lack of trust or the stigma that may be associated with the whole process. It has also been reported that indigenous populations seem to have limited knowledge of or access to available treatments as they are only accessing specific types of therapies; for example, they may be unfamiliar with ABA services' availability.
Indigenous populations have reported that treatment providers often provide excuses regarding the unavailability of treatment options (Study 31). Biases for or against indigenous or non-indigenous populations have been reported; for example, the existence of a western bias (Study 24) or the lack of recognition or under-estimation of cultural differences (Study 5). Lastly, reflective practices require considering the different usage of language as a modality (e.g., cultural connotations) and sourcing the means that can resolve the matter (e.g., access to interpreters). Building awareness and openness to other people's cultural beliefs and building the competency to be part of a diverse relationship (e.g., seeking ongoing feedback and needs in the process of cultural adaptation) is a core pre-requisite of success in this endeavor.
Discussion
The aim of this scoping review was to explore barriers and facilitators for access and participation in psychological services with a behavioral component (e.g., ABA services), as well as tools and practices for effective and equitable delivery of psychological services for Māori and other Indigenous populations. This scoping review revealed that the way therapists' practice may determine the level of opportunities provided for effective and equitable services by either practitioners or organizations/institutions they are representing. Our thematic analysis organized the information extracted from the literature around three key elements that expanded our understanding of barriers and facilitators: connection; innovation; and reflection. The analysis suggests that successful culturally appropriate practice may be facilitated by bringing together our practice and the recipients of interventions (connection), showing flexibility and persistence to find solutions (innovation), and evaluating the role of our own behaviors in this context (reflection). In summary, our findings aligned with current knowledge from across the health, disability and welfare sectors: disparities in the access to services and in the quality of services are apparent between Indigenous and non-Indigenous service users in all CANZUS countries. Therefore, our findings contribute to the existing body of research into cultural adaptations of psychological and behavioral interventions e.g., (11–13, 22) and highlight the importance of cultural adaptations and their specific benefits to ABA-based interventions across a wide range of cultures and countries. Thus, this review may also encourage professionals worldwide to identify barriers for such adaptations and inform strategies to overcome such barriers.
In applying theories and practices of psychology, any psychological service that is committed to behavior change has to adhere to the technology of behavior (10). ABA research predominantly bases therapy on the understanding of learning mechanisms and behavior change. However, the scarce number of published papers in the ABA literature suggests that behavior analyst have given little attention to the effect of cultural variables. One possible explanation for the paucity of relevant ABA literature could be the challenge of defining or classifying behaviors or practices as “culturally adapted” in measurable terms or the challenge of investigating how such behaviors are acquired. Take for example a Māori client who always arrives late or skips sessions because s/he is too embarrassed to let the practitioner know that s/he cannot afford to take leave from work. In this example, which behaviors or practices could a therapist adopt that can be classified as “culturally appropriate” to promote accessibility?
Outside the cultural context of the anglophone world, behavior analysts often use ethnic cultural behaviors to facilitate access to services. However, there has been no research investigating how individual ABA practitioners adapt their approaches and interventions in their respective cultural contexts, nor have such practices been highlighted in individual case studies. This lack of reports on cultural adaptations is observed across all schools of approaches to psychological intervention (15). Opening a discussion about research into how cultural practices can enhance the accessibility and effectiveness of interventions could be the pathway toward a better understanding of potential outcomes of cultural adaptations.
Asking such wh- questions could become a helpful tool for effective delivery of psychological services based on the three themes (connection, innovation, reflection) that emerged from our thematic analysis. It can generate further questions (reflective practice) or even put a measurement system in place for behaviors that contribute to cultural adaptation (innovative practice). Another potentially useful application of this review's findings could be for the psychologist or behavior analyst to consider what behaviors (connecting practices) have assisted their client to stay in therapy and allowed the client to decide what works best for them. Such an approach could promote our understanding of who cultural adaptations are suitable for, as cultural adaptations cannot come as a “one-size-fits-all.” Each Indigenous individual may identify with a specific subgroup but also has unique experiences from living in a westernized world. The literature reports mixed outcomes e.g., (25) of efficacy and effectiveness of current culturally adapted practices and this scoping review is adding its bit in the direction of client-tailored, individualized approaches.
The importance of cultural adaptation to psychological practices cannot be overstated. In recent years, professional psychological associations (e.g., the American Psychological Association, the British Psychological Society, the Australian Psychological Society, the Canadian Psychological Association, and the NZ Psychological Society) have recognized cultural diversity as an important element of service users' experiences and lived reality and have developed practices and statements to affirm cultural respect as an ethical and professional expectation from their membership. However, a recent survey in New Zealand stands out as an example of the concerns Indigenous populations (Māori and Pasifika) have about the globalized model of evidence-based interventions built on a narrow, colonized view of evidence not aligning with Indigenous worldviews and undermining innovation (70). Plessas, McCormack and Kafantaris have discussed how the science of ABA can become responsive to Māori culture and how behavior analysts can make such contributions on all levels (practitioners, service providers and institutions) (30). A possible contribution of behavior analysts living and working in CANZUS countries could be to engage in collaborative initiatives with other fields of psychology in order to apply the technology of behavior to already constructed models of indigenous health and well-being (e.g., Te Whare Tapa Whā, Te Wheke, etc.), thus promoting a paradigm shift. Actions such as the new Code of Ethics for Behavior Analysts (71) effective from January 2022, make an explicit reference to our obligation to engage in activities that promote diverse therapeutic relationships. This requirement aligns with our three themes of connection, innovation and reflective practice. The more we explore barriers and facilitators of access to psychological services for behavior change, the more opportunities we find to improve the quality of life of our people.
This scoping review is part of a larger investigation, and will inform the development of a survey to answer two main questions: what are the barriers and facilitators, and what tools and practices exist in psychology (with a behavioral component) for an effective and equitable service delivery for Indigenous populations. Yet, the findings of this review can already inform practitioners on the importance of connecting, innovative and reflective practices when working with Indigenous clients.
Strengths and Limitations
Although we used a comprehensive search strategy, it is possible that not all relevant papers were found. The reviewed literature did not always provide detailed information. For example, the Indigenous populations' socioeconomic status often was not explicitly defined. Further, there was heterogeneity of intervention designs and we could not assess the procedural integrity of the analyzed studies. This review was also limited in that we restricted our search to Indigenous populations in CANZUS nations only. New Zealand Māori do share similar histories of colonization with other CANZUS Indigenous Nations, though their experiences may have been different. Thus, our findings may be limited in their applicability to Indigenous populations in other countries (such as Indigenous populations in South America or Southeast Asia).
However, this review still allows for a broader view of the barriers and facilitators to psychological services for Indigenous individuals by including a large number of studies with multiple viewpoints. Parent training and adapted CBT were the two primary interventions examined in the literature reviewed, begging the question why cultural variables have not been examined in the context of other interventions. Though this is limiting the analysis to a narrow array of psychological services, the studies reviewed still provide us with useful information about a diversity of cultural adaptation efforts. This first review targeting psychological services with a behavioral component may unlock additional avenues to understanding some key elements of cultural adaptations enhancing the goal of behavior change.
Conclusion
The findings of this scoping review suggest that connection, innovation and reflective practice are key to creating opportunities for effective and equitable services (either at a practitioner's level or that of an organization or institution). Our analysis suggests that our own actions determine the level of success we can attain in bringing together our practice and the recipients of treatment (connection), showing flexibility and persistence in finding solutions (innovation) and examining the role of our behavior in reaching our collaborative therapeutic goals (reflection). This information may contribute to building contemporary practices suitable for all and may thus assist therapists to broaden their scope of practice.
