Addiction is a syndrome with common causes and multiple expressions, leading to clinically significant impairment or distress. DSM-5 broke new ground in May of 2013, designating a new disorder called "behavioral addiction" or “non-substance addiction”. Gambling and gaming disorders are similar to substance use disorders, such as the existence of withdrawal symptoms, tolerance, continued use despite negative consequences, and loss of control over activities.
However, other types of behavioral addictions such as social media or smartphone use disorder, non-suicidal self-injury (NSSI), binge eating, sun-tanning, compulsive buying, and compulsive sexual behaviors may be shared etiology-based addictions. For example, recent studies have found that NSSI is associated with the mechanism of addiction to pain stimuli, and the reward neural circuit with the orbitofrontal cortex as the core may play an important role in the pathogenesis of adolescent NSSI, supporting a shared neurocircuitry of NSSI and substance use disorders. Thus, more research is needed regarding the underlying mechanisms of these risk behavior and the similarities or dissimilarities with addictive behaviors.
To better understand the connotation of substance and non-substance addiction, the goal of this Research Topic is to collect and review knowledge of all maladaptive and repetitive behaviors of the underlying motivational mechanisms of addiction. Expanding the lens of sociocultural (influences of family, friends, and broader culture), psychological (emotional, behavioral, and cognitive factors), or neurobiological evidence (genetic or epigenetic predispositions, functional and structural magnetic resonance or PET studies) to explore risk behavior and its connection to addiction. We encourage submissions from the basic research of substance addiction, as well as from clinical and intervention studies of gambling disorder, gaming disorder, non-suicidal self-injury (NSSI), binge eating, compulsive buying, compulsive sexual behaviors, and so on.
The Research Topic will cover, but is not limited to the following sub-topics:
- Emerging diagnostic entities in the behavioral addiction category.
- Reliability and validity of measures assessing risk and addictive behavior in terms of clinical symptoms.
- Impact of psychological and environmental risk factors on risk behavior and the underlying additive mechanisms.
- Neurobiological or neuroimaging evidence of risk behavior or diagnosed addiction.
- Interactions of environmental factors and molecular genetics pathways with developing computational and statistical methods on risk behavior, also in the context of addiction.
-Pharmacological and non-pharmacological approaches(rTMS, psychotherapy, or digital healthcare) for treating risk behavior associated with addiction.
