Background: Research has shown that caregivers of persons with psychosis play an invaluable role in recovery, but unfortunately, often report high levels of distress. While cognitive models of caregiver distress have been well-supported, there is still limited knowledge of the psychological factors involved. Recent advances in cognitive behavioral therapy seem to converge on the importance of acceptance- and mindfulness based processes.
Aim: To examine the impact of psychological flexibility on caregiver distress in the early phases of psychosis, while controlling for known predictors of caregiver distress.
Method: Within a cross-sectional design, 101 caregivers of 38 persons with first-episode psychosis in a clinical epidemiological sample completed a series of self-report measures.
Results: A linear mixed model analysis found that, after controlling for caregiver socio-demographic factors, service user symptoms, drug use and global functioning, psychological flexibility was a significant predictor of caregiver distress.
Conclusion: Greater level of psychological flexibility in caregivers, seems to be related to lower levels of caregiver distress. This finding corresponds to studies within a broad range of emotional disorders. There may be important clinical implications in terms of facilitating the process of acceptance through interventions from the ‘third-wave’ or contextual cognitive behavioral therapies.
Introduction
Research has shown that caregivers of persons with psychosis often play an invaluable role in recovery, and that a family environment characterized by warmth and low levels of criticism is associated with reduced risk of relapse (O’Brien et al., 2006; Lee et al., 2014). This is also reflected in service user perspectives on psychosis and recovery, that often highlight the importance of significant others (Jansen et al., 2015c). However, research also shows that caregivers report high levels of distress (Kuipers et al., 2005; Jansen et al., 2015b). Unfortunately, caregiver distress often feeds into ‘vicious circles’ (Kuipers et al., 2002): high levels of distress takes a toll on their mental resources, leading to higher levels of criticism and less energy to support the person with psychosis, which may exacerbate psychotic symptoms and increase the likelihood for relapse. This, in turn, increases caregivers’ feeling of hopelessness and distress. A number of studies have shown that structured family work reduces the risk of relapse, and improves the possibility of recovery in persons with psychosis (Pitschel-Walz et al., 2001; Pilling et al., 2002).
While cognitive models of caregiver distress have been well-supported, there is still limited knowledge of the psychological factors involved (Jansen et al., 2015a). Most of the studies focus on the service users, with comparably less focus on caregivers themselves. The lack of focus on caregiver distress, independent of the potential impact on the service user, has recently caused experts in the field to call for a separate caregiver support service (Kuipers, 2010). However, while we know a lot about effective strategies for supporting families facing psychosis, less is known about what makes some persons more distressed than others, or the ‘effective ingredients’ in these programs (Jansen et al., 2015a).
A number of treatment programs have been developed, mostly within a psychoeducational framework, based on cognitive behavioral principles, and their evidence in reducing relapse is considered robust (Pitschel-Walz et al., 2001; Pfammatter et al., 2006). Recent advances in cognitive behavior therapy seem to converge on the importance of acceptance- and mindfulness based processes when dealing with anxiety, depression and general distress. This is often referred to as the ‘third-wave’ of CBT (Hayes, 2004a) or contextual behavior therapy (Hayes et al., 2013) and examples include Dialectical Behavioral Therapy (DBT; Linehan, 1993), Metacognitive Therapy (MCT; Wells, 2000), Mindfulness-based Cognitive Therapy (MBCT; Segal et al., 2002) and Acceptance and Commitment Therapy (ACT; Hayes et al., 1999). The ‘third wave’ expands, rather that replace, traditional cognitive behavioral therapy, and share the common focus of helping the client relate to their thoughts differently, while de-emphasizing the need to change or ‘restructure’ specific cognitions (Tai and Turkington, 2009). In other words, the focus is more on the process rather than content of thinking. However, these processes have been less thoroughly examined within the field of family work. Jansen et al. (2014a) found that dysfunctional meta-cognitions, often related to increased worry and rumination, were related to caregiver distress, and that emotional over-involvement seemed to work as a mediator between these metacognitions and distress. In general, caregiver distress is beginning to emerge as a potential focus for mindfulness-based approaches (Epstein-Lubow et al., 2006; Minor et al., 2006). In a feasibility and acceptance study, Moorhead (2012) found that an 8 week mindfulness intervention was well-received by carers and service users, with promising effects on distress measures.
Acceptance and Commitment Therapy (Hayes et al., 2012b) targets experiential avoidance and a lack of flexibility and persistence in pursuing valued life directions. Experiential avoidance refers to an unwillingness to experience distressing emotions, or attempts to avoid internal experiences, including thoughts, feelings, memories, and physical sensations – even when doing so creates harm in the long-run (Hayes et al., 1999). The aim of ACT is to foster the opposite, namely ‘psychological flexibility,’ a process which is thought to be one of the central mechanisms of change in acceptance-based therapies. Psychological flexibility refers to an individual’s ability to connect with the present moment fully, to accept the thoughts, feelings and bodily sensations that ‘show up,’ and to persist in behavior that is in line with personal values (Hayes et al., 1999). Accordingly, distress is directly related to lack of psychological flexibility. Studies have found ACT to be effective in managing a number of disorders, including depression, anxiety, stress, psychosis, epilepsy, and pain (Hayes et al., 2006; Ost, 2008; Powers et al., 2009). Moreover, data from mediation analyses also suggest that psychological flexibility is the central therapeutic mechanisms behind the improvement (Ruiz, 2010; Vilardaga et al., 2013).
As a preliminary step toward examining the usefulness of acceptance-based approaches for caregivers of persons with psychosis, the aim of the current study was to examine the association between psychological flexibility and caregiver distress. We hypothesized that higher levels of acceptance would be associated with reduced caregiver distress, even when controlling for known predictors, including emotional involvement and subjective appraisal of burden, as well as service user characteristics such as symptoms and global functioning (Baronet, 1999; Tennakoon et al., 2000; Wolthaus et al., 2002; Addington et al., 2003; Boydell et al., 2013; Jansen et al., 2015b).
Materials and Methods
Design and Participants
The study had a cross-sectional design, and participants were relatives of persons with first-episode psychosis (age 18–35 years old). The sample is drawn from a larger intervention study and consists of follow-up data on this cohort. Service users were consecutively approached for inclusion upon receiving a schizophrenia spectrum disorder within Region Zealand in Denmark (population: 816,670) between April 2011 and April 2013. The inclusion criteria were: (1) meeting ICD- 10 criteria for schizophrenia spectrum disorders (F20–29, except F21), (2) first-ever psychiatric treatment for this diagnosis, (3) age 18–35. The only exclusion criterion was insufficient Danish skills for the interview to be completed. There were no additional inclusion/exclusion criteria for caregivers. The number of eligible individuals were 38 service users enrolled in the outpatient treatment service based on assertive community treatment principles (OPUS) together with 101 caregivers. Diagnoses were verified using operational criteria checklist (OPCRIT; McGuffin, 1991) by a clinical psychologist, MD or psychiatrist.
Measures
Family Questionnaire (FQ; Wiedemann et al., 2002)
Expressed Emotion (EE) was assessed by the FQ, a 20-item self-report measure rated on a four-point Likert scale (‘never/very seldom,’ ‘seldom,’ ‘often,’ or ‘very often’). Participants are asked about everyday challenges with statements like ‘I have a tendency to neglect myself because of her/him’ and ‘she/he irritates me.’ The measure is divided into two subscales: emotional over-involvement (EOI) and critical comments (CC). EOI includes over-intrusive, self-sacrificing, over- protective behavior or exaggerated emotional response and over-identification with the service user; CC is defined as unfavorable comments on the behavior or personality of the service user (Vaughn and Leff, 1976). The items are scored from 1 to 4 yielding a maximum score of 40 in each subgroup. Caregivers are classified as high EE if they score 23 or greater on the CC subscale or 27 or greater on the EOI subscale. Wiedemann et al. (2002) found the FQ to have good psychometric properties including a clear factor structure, good internal consistency of subscales and good concurrent validity in relation to the widely used Camberwell Family Interview (Vaughn and Leff, 1976). They also found that the FQ displayed similar level of accuracy and higher sensitivity compared with the Five Minute Speech Sample (Magaña et al., 1986).
Experience of Caregiving Inventory (ECI; Szmukler et al., 1996)
Subjective appraisal of caregiving was assessed by the Experience of Caregiving Inventory (ECI), a 66-item self-report questionnaire. The questionnaire consists of 10 subscales: eight negative areas of caregiving (difficult behaviors, negative symptoms, stigma, problems with services, effects on the family, need to provide back-up, dependency and loss) and two positive (positive personal experiences and positive aspects of the relationship). Participants are asked how frequently they have thought about a series of issues during the last month. The items are scored on a five-point Likert scale with the response categories ‘never,’ ‘rarely,’ ‘sometimes,’ ‘often,’ and ‘nearly always.’ The maximum score for the combined negative subscales is 208 (higher scores equals more negative appraisals) and 56 for the positive subscales (higher scores equals more positive appraisals). The internal consistency and construct validity of the ECI have been found to be high (Szmukler et al., 1996; Joyce et al., 2000).
General Health Questionnaire 30 (GHQ; Goldberg and Williams, 1988)
The level of distress was measured using the General Health Questionnaire 30 (GHQ-30), which is a 30-item self-report questionnaire. For each item, the caregivers must rate symptoms on a four-point Likert scale ranging from 0 to 3, with a maximum score of 90 (‘better than usual/more so than usual,’ ‘same as usual,’ ‘less than usual,’ and ‘much less than usual’ for the positively worded items; and ‘not at all,’ ‘no more than usual,’ ‘more than usual,’ and ‘much more than usual’ for the negatively worded items). Higher scores signify greater distress. The scale has shown high internal consistency and good retest reliability, as well as concurrent validity with a number of other clinical assessments (Goldberg and Williams, 1988).
Acceptance and Action Questionnaire II (AAQ-II; Bond et al., 2011)
The Acceptance and Action Questionnaire II (AAQ-II) is a 10-item self-report measure, and is the most recent version of the widely used measure of psychological flexibility, experiential avoidance and acceptance of private experiences (Hayes, 2004b). Participants are asked to indicate agreement with statements (e.g., “It’s OK if I remember something unpleasant”) on a seven-point Likert scale (‘always true’ to ‘never true’). High scores reflect greater psychological flexibility. The AAQ has adequate internal consistency (Cronbach’s alpha = 0.84) and acceptable test–retest reliability (r’s = 0.81 and 0.79) (Bond et al., 2011).
Positive and Negative Syndrome Scale for Schizophrenia (PANSS; Kay et al., 1987)
Service user symptomatology were assessed with Positive and Negative Syndrome Scale for Schizophrenia (PANSS), a 30-item instrument, rated on a scale from 1 to 7. Participants are asked to report symptoms during the past week, and higher scores indicate more severe symptoms. PANSS is considered the most widely used instrument for symptoms in schizophrenia spectrum disorders in clinical trials. Psychometric properties have been found to be adequate (Peralta and Cuesta, 1994; Santor et al., 2007). PANSS were divided into positive, negative, disorganized, excitement, and emotional distress scores based on van der Gaag et al. (2006). Global functioning was measured using the DSM-IV’s Global Assessment of Functioning scale (GAF; American Psychiatric Association [APA], 1987).
Procedure
Once the persons with psychosis were enrolled in the early psychosis intervention service (OPUS), they were approached for participation in the study. Following oral and written information about the study, and then written consent, caregivers were asked to fill out the four questionnaires and service users were asked to participate in a semi-structured diagnostic interview. All participants gave written consent to be contacted for 3-year follow-up interviews. All participants were debriefed following the completion of the questionnaires and the PANSS, but none of the respondents reported any adverse experiences in answering the questions. The Regional Committee for Research Ethics approved the study (reg.nr. 2008580020).
Statistical Analyses
All statistical analyses were conducted using SPSS version 20 for Mac (IBM, Inc., Chicago, IL, United States). First, descriptive statistics of socio-demographic and clinical variables were calculated using means and standard deviations for quantitative variables and frequencies with percentages for categorical variables. Second, to accommodate for multiple caregivers per service user, and the possible correlation between them, a linear mixed model regression analysis was carried out to test the primary hypothesis.
Results
Sample Characteristics
The characteristics of the sample are presented in Table 1. From a total of 70 families, there were 101 caregivers between 28 and 72 years old (Median: 53) and 38 service users between 21 and 35 (Median: 23). A further 27 eligible service users did not participate, while 4 of these accepted for the caregivers to be involved. The majority of caregivers were female, living with the services users and employed.
Questionnaires and Clinical Measures
The mean scores for GHQ was 28.35 (SD: 15.21). The mean scores for EOI was 23.14 (SD: 5.15) and for CC 18.23 (SD: 5.21), which is considered as low levels of expressed emotion. The mean score for ECI negative subscale was 110.79 (SD: 32.02) and ECI positive subscale was 39.75 (SD: 8.37). PANSS and GAF scores are presented in Table 1.
Predictors of Caregiver Distress
The results of the linear mixed model analysis with distress (GHQ-30) as the main outcome are presented in Table 2. Higher scores on the AAQ-II, suggestive of greater psychological flexibility were significantly related to reduced caregiver distress (β = 0.79 [95% CI: 0.23 – 1.35]; p = 0.009). Results remained significant after controlling for caregivers’ gender, cohabitation and employment status, the level of symptoms, overall level of functioning and drug abuse in service users, and finally, other known predictors in caregivers such as subjective burden and the level of expressed emotion.
Discussion
The current study examined the association between psychological flexibility and caregiver distress. Supporting our hypothesis, caregivers with higher levels of acceptance reported less distress. The result remained significant after controlling for caregiver demographic characteristics and known predictors such as emotional involvement and subjective appraisal of burden, as well as service user characteristics such as symptoms, global functioning, and drug abuse.
The positive association between psychological flexibility, as measured by the AAQ-II, and emotional distress, corresponds to findings from a range of studies, including depression, anxiety, stress, psychosis, epilepsy, and pain (Hayes et al., 2006; Ost, 2008; Powers et al., 2009). Psychological flexibility is considered the central mechanisms of change in these studies, as suggested by mediation analyses (Ruiz, 2010). This may be of importance since caregivers often report distress levels reaching thresholds for clinical significant symptoms such as depression, anxiety and post-traumatic stress disorder (Martens and Addington, 2001; Onwumere et al., 2011; Jansen et al., 2015b).
Studies suggest that caregivers in the early phase of psychosis, are extra vulnerable to distress, as they often experience grief and shock, and may have little prior knowledge of illness and the psychiatric system (Addington and Burnett, 2004). Finding ways to work through these difficulties demands time, energy and personal involvement from the whole family. Research has suggested that acceptance may be a central part of coming to terms with these changes. However, acceptance from the perspective of ‘third wave’ CBT, including ACT and mindfulness-based approaches, is not a passive response to suffering or incomplete recovery, but rather an active stance or ‘willingness’ to ‘be with’ the experience, ‘as it is,’ while engaging in or pursuing personally meaningful behavior (Hayes et al., 2012a; Jansen and Morris, 2016). For caregivers, thus, greater acceptance does not mean giving up hope for recovery. On the contrary, it means ‘making space’ for the anxiety, sadness, anger and grief, that is understandable and inevitable when supporting a person with psychosis. Mindfulness is a core component in acceptance-based therapies, and involves the cultivation of awareness, insight, wisdom, and compassion (Kabat-Zinn, 1990, 1994, 2003). In mindfulness, participants practice the skill of noticing distressing thoughts and feelings, holding such experiences in awareness, and meeting them with acceptance and self-compassion. This is a skill that can be learned and practiced, together with the other components of effective family work, including problem solving, psychoeducation and communication skills.
Some of the challenges families often deal with is loss of control, including a reduced sense of freedom and to some extent the relationship they used to have with their relative (Patterson et al., 2005). However, while the focus in research traditionally has been on caregiver ‘burden,’ the experience of caregiving is complex, and comprises both negative and positive experiences (Joyce et al., 2003; Jansen et al., 2014b). Caregivers also describe rewarding experiences, in addition to the pain, including increased closeness in the family and better understanding of other people’s suffering (Szmukler, 1996; Szmukler et al., 1996). This corresponds with the vast literature on post-traumatic growth, suggesting that people exposed even to the most traumatic events may perceive at least some good emerging from their struggle, including changes in self-perception, changes in interpersonal relationships, and a changed philosophy of life (Tedeschi and Calhoun, 1996; Park and Helgeson, 2006; Jordan et al., 2017). This also resonates with ideas within the recovery movement, which holds that you can live satisfying, meaningful lives, despite of experiencing distressing symptoms (Davidson et al., 2005). Taken together, expanding therapeutic interventions, to also encompass work on acceptance processes, as well as increasing hope, values and meaningfulness, may accommodate the challenges delineated above.
There are some limitations to this study. First, the cross-sectional design precludes firm causal inferences. It may be possible for instance, that lower levels of distress led participants to report being more accepting of difficult thoughts and emotions. Second, caregiver inclusion was based on consent by the service users, which represents a potential selection bias, as service users with better relationships with caregivers may have been more inclined to consent. Finally, our participants were White Danish adults; we do not know whether the findings generalize to other ethnic groups. There are also several strengths of the study. First, the comparably large sample drawn from a specialist early intervention service within a defined catchment area increases the likelihood of a representative sample. Second, the study adjusted for several confounders, which adds to the robustness of the predictor. Finally, two caregivers were included per service user in a multilevel analysis, which increases the number of males included compared to most studies.
With the limitations and strengths in mind, these findings may have important clinical implications. First, these initial findings are promising and add to the body of research showing that acceptance and mindfulness-based therapies can be used for people with psychosis and their caregivers (Chadwick et al., 2005, 2009; White et al., 2011; Jansen and Morris, 2016) as well as research on caregivers in other populations (e.g., Losada et al., 2015). Second, supporting caregivers in the process of accepting, or ‘making space’ for distress, while simultaneously addressing personally meaningful behaviors or values related to being a caregiver, may both instill hope and improve coping skills for difficult thoughts and feelings. This may broaden the intervention repertoire used in family support programs to better address the specific needs of the family.
