Big ideas series: self-regulation shift theory: trauma, suicide, and violence.

BACKGROUND: Traumatic stress, suicide, and impulsive violence arguably are three of the most consequential problems facing societies today. Self-regulation shift theory is introduced to capture the underlying coping dynamics involved in these three grave challenges. OBJECTIVES: Self-regulation shift theory, based in a nonlinear dynamical systems framework, focuses on critical psychological self-regulation thresholds and the role of cognitive self-appraisals in human adaptation to help understand these three significant societal challenges. METHODS: This essay reviews existing evidence within the posttraumatic adaptation process utilizing SRST for understanding dynamic self-regulation. This is followed by integrating SRST within existing current theoretical models for suicidal behaviors and violent outbursts. CONCLUSIONS: The essay concludes with methodological suggestions for future research applying SRST and how this research offers important opportunities to develop early warning systems that promote hope when hope seems impossible.

Not how often but when: Self-efficacy to control cannabis use and PTSS.

OBJECTIVE: Cannabis use is prevalent with trauma survivors. Yet, the effects of cannabis use on posttraumatic stress symptoms (PTSS) have been equivocal with some studies showing a positive association and some showing a negative association. Integrating the self-medication hypothesis and social cognitive theory (SCT), the present study aimed to elucidate differential outcomes by considering frequency of cannabis use and self-efficacy to control cannabis use in different contexts (i.e., social facilitation, opportunistic, and emotional relief) in relation to PTSS. METHOD: Undergraduate students (N = 314) who endorsed lifetime trauma exposure and past-month cannabis use completed self-report measures assessing cannabis use behaviors, self-efficacy to control use, and PTSS. RESULTS: Parallel mediation revealed that initially, greater frequency of cannabis use was associated with PTSS severity (ß = .16, SE = .09, p = .004). With the inclusion of emotional relief self-efficacy, opportunistic self-efficacy, and social facilitation self-efficacy to control cannabis use as parallel mediators, frequency of cannabis use no longer predicted PTSS severity. There was also a significant indirect effect of emotional relief self-efficacy to control cannabis use on frequency of use and PTSS (95% CI [.14, .31]). CONCLUSIONS: Self-efficacy to control cannabis use during moments of emotional distress could serve a critical role in the relationship between cannabis use and PTSS. These results may inform clinical intervention and provide survivors with a better understanding of how use impacts recovery. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
