To clarify the rationale behind Posttraumatic Growth (PTG), a model by Schaefer and Moos describes the relative contribution of environmental resources, individual resources, event related factors, cognitive processing and coping (CPC) on PTG. In the present study, this model was tested with the spouses of myocardial infarction patients with data from various hospitals in Turkey. A structural equation model revealed that neither individual nor environmental resources had indirect effects on PTG through the effect of event-related factors and CPC, while they showed direct effects on PTG. The findings were discussed in the context of the theoretical model. © 2010 SAGE Publications Los Angeles, London, New Delhi, Singapore and Washington DC.
