However, no study has examined whether the two constructs reflect distinct aspects of psychological functioning or whether they can be clearly differentiated from mental health symptoms and associated impairment. Adolescence is a key period for the onset of mental health problems, making a better understanding of psychological processes involved in mental health in this age group important. The Difficulties in Emotion Regulation Scale (DERS-16, emotion dysregulation) and the Avoidance and Fusion Questionnaire for Youth (AFQ-Y8, psychological inflexibility) are widely used assessment tools of emotion dysregulation and psychological inflexibility, but critical evaluations of their validity are sparse. Using exploratory and confirmatory factor analysis, we examined the discriminant validity of emotion dysregulation and psychological inflexibility as measured via the DERS-16 and the AFQ-Y8 in a sample of 633 adolescents (M_age = 16.6 [1.98]). Emotion dysregulation and psychological inflexibility did not demonstrate discriminant validity. Instead, four strongly correlated factors emerged, each comprising a combination of items from both assessment tools: (1) interference stemming from distressing thoughts and emotions, (2) negative self-evaluation, (3) loss of control when emotional, and (4) confusion about one's emotions. These factors were strongly correlated and adequately captured by an overarching factor, which we termed the X factor, which in turn was very strongly correlated with core symptoms of anxiety and depression and functional impairment stemming from mental health issues. In conclusion, the constructs of emotion dysregulation and psychological inflexibility, as assessed by the DERS-16 and AFQ-Y8, do not show discriminant validity in adolescents. Furthermore, the constructs measured by these tools are almost empirically indistinguishable from anxiety, depression, and functional impairment.</div></div>","PeriodicalId":47544,"journal":{"name":"Journal of Contextual Behavioral Science","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we leveraged system dynamic methods and contextual-behavioural science (CBS) approaches to support the development of interventions focusing at addressin these risk factors. Using Causal Loop Diagram methods (Vensim PLE), we collected qualitative data from college students to generate Network Feedback Loops (NFLs) (<em>n</em> = 24, Maged 22 years old), during the development phase of the MyUse: a contextual behavioural change intervention for harm reduction practices at college students. The findings underscored central nodes (determinants within an intervention) that support our previous identified three CBS-harm-reduction practices for college students (targeted edges: mindful drug-use decision making, value-based activities, context-sensitive personalized plan of harm reduction). Analyses revealed 4 NFLs for students with previous drug use, consisting of 13 edges (4 positive, 2 negative, and 4 balancing reinforcing relationships) and 3 NFLs for students with no previous drug use, consisting of 4 positives, one negative, and one balancing relationship. All the NFLs were nested with the three CBS-related targeted outcomes. College students who use drugs need drug-related knowledge about the unpredictable and adverse effects of drugs, presented in a compassionate way and distributed from credible resources (e.g., students’ unions/club). Students with no previous drug use need education about the effects of drugs and awareness of how drugs can devaluate value-based activities (e.g. sports, friendships, social life). These should be delivered via proxy cue reminders and mobile-text approaches conveying messages about drug use susceptibility, distributed in real-time. Idiosyncratic, dynamic, and contextual-bound factors of lapse risks or preventive practices should account for each person-specific vulnerabilities via personalized harm reduction plans.</div></div>","PeriodicalId":47544,"journal":{"name":"Journal of Contextual Behavioral Science","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142527019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These ‘givens’ of existence include death, identity, isolation, meaning, and freedom. From this theoretical perspective, all branches and brands of psychotherapy need to include some procedures to address these issues. Evidence for the importance of these constructs in human experience is presented, followed by evidence for existential therapies themselves. A dearth of quality research trials establishing a strong evidence base for this branch of therapy was noted. Further, process-based research in this area was shown to be weak. That is, few researchers have sought to show that the hypothesized processes are responsible for the changes observed in existential therapy.
