Psychosocial functioning in veterans with combat-related PTSD: An evolutionary concept analysis.

Veterans returning from combat have a greater risk for developing posttraumatic stress disorder (PTSD) and greater severity of psychosocial functioning impairment. Previous research has demonstrated the strong association between PTSD and psychosocial functioning impairment. Psychosocial functioning is an ambiguous term often used in literature to discuss PTSD-associated consequences, intervention response, and symptom progression. An evolutionary concept analysis was conducted to clarify understanding of psychological functioning in veterans with combat-related PTSD. Rodgers' method for an evolutionary concept analysis was used to examine the concept of psychosocial functioning. A literature search using the Cumulative Index to Nursing and Allied Health Literature and SCOPUS databases and subsequent screening yielded twenty articles meeting established criteria for analysis. The analysis highlights significant attributes, antecedents, consequences, and implications for future concept development. Psychosocial functioning environment/domain, social support, and engagement in treatment were distinguishing attributes identified. Combat exposure and various PTSD symptoms are related antecedents. Consequences such as decreased intimacy, decreased work function, low parenting satisfaction, and inadequate productivity in educational settings are all components of this concept. The concept of psychosocial functioning is meaningful in the everyday lives of US combat veterans with PTSD and requires special consideration in treatment planning by healthcare providers.
