Post-traumatic growth (PTG) is the experience of positive changes that can follow a traumatic event. The current study examined the factorial as well as the discriminant validity of the German version of the Post-traumatic Growth Inventory (PTGI-G) in stroke patients. A total of 188 adult stroke patients (63.3% male; median age 69 years) completed the PTGI-G and the German version of the Hospital Anxiety and Depression Scale (HADS-D) at the end of their inpatient rehabilitation. Confirmatory factor analyses indicate an acceptable model fit of both the original five-factor solution as well as a second-order factor model of the PTGI-G (CFI > .95; RMSEA < .01). Small and non-significant correlations between the PTGI-G subscales and the depression scale of the HADS-D support the discriminant validity of the PTGI-G. The PTGI-G appears to be a valid tool in the context of stroke research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
