ABSTRACT
Posttraumatic Growth (PTG), characterized by newfound meaning, perspective, and purpose for trauma survivors, remains enigmatic in its nature. This state is thought to arise from the dynamic interplay of biopsychosocial factors; however, the nature of this interplay is unclear. This study aimed to investigate the intricate relationship between PTG and facial affect dynamics, shedding light on the complex interplay of biopsychosocial factors that underpin this transformative process. We conducted a comprehensive investigation involving 19 wildfire survivors who provided daily self-reported PTG ratings alongside smartphone videos analyzed using Automated Facial Affect Recognition (AFAR) software. Our findings revealed compelling evidence of self-organization within facial affect, as indicated by notably high mean R2 and shape parameter values (i.e., nonlinear indices indicative of structural integrity and flexibility). Further regression analyses unveiled a significant interaction between the degree of facial affect 'burstiness' and coping self-efficacy (CSE) on PTG. This interaction suggested that PTG development was a nuanced process intricately linked to the coherence of emotion patterns exhibited by individuals. These insights illuminate the multifaceted dynamics at play in the emergence of PTG and contribute to a broader understanding of its biopsychosocial foundations.

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.
