Multidisciplinary Recommendations for Improving the Credibility of Research on Posttraumatic Growth

Research on posttraumatic growth (PTG) is widely invoked as evidence that adversity can catalyze positive change. However, existing research often conflates coping with transformation, relies on culturally specific assumptions, and lacks a clear standard for what counts as growth. Integrating philosophy, personality science, and cultural psychology, we articulate six necessary criteria—lasting change, conceptual distinctiveness, meaningful positivity, normative significance, causal linkage to trauma, and empirical verifiability—that a credible PTG account must satisfy. We propose a virtue-based framework that meets these criteria, reconciling universal aspirations with context-sensitive manifestations of character virtues in the context of adversity. This multidisciplinary synthesis resets PTG science on a clearly defined, culturally plural, and normatively robust footing by defining enduring post-traumatic positive change as the cultivation of culturally situated virtues .
