Indirect Associations Between Posttraumatic Stress Symptoms and Other Psychiatric Symptoms, Alcohol Use, and Well-being via Psychological Flexibility Among Police Officers.

Police officers experience a high number of potentially traumatic events (PTEs) often associated with elevated posttraumatic stress symptoms (PTSS). In addition, PTSS are related to co-occurring psychiatric symptoms (e.g., anxiety, depression), alcohol misuse, and low perceived well-being. Yet, behavioral processes that may account for the associations between PTSS and unfavorable outcomes remain unspecified. Psychological flexibility, or one's response to private experiences (e.g., PTE-related memories) with an open, aware, and active approach, may be one such process. The present study aimed to evaluate psychological flexibility as both a mediator and moderator of PTSS and commonly co-occurring psychiatric symptoms, alcohol use, and general well-being, using cross-sectional data provided by a sample of police officers (N = 459) recruited from three regionally distributed U.S. police agencies. Structural equation modeling indicated a well-fitting model wherein psychological flexibility indirectly accounted for associations among PTSS and endogenous outcomes, χ2 (107, N = 457) = 225.33, p < .001, CFI = .99, TLI = .98, RMSEA = .05, 90% CI [.04, .06], SRMR = .03. Psychological flexibility also moderated associations between PTSS and psychiatric symptoms, B = 1.58 (SE = 0.22), p < .001; and well-being, B = -3.84 (SE = 0.46), p < .001. Although additional research is needed, these preliminary results suggest psychological flexibility may be a behavioral process that accounts for negative outcomes associated with PTSS and a productive intervention target in the context of PTSS and generalized distress. Further research regarding the role of psychological flexibility in PTSS-related outcomes for police officers appears warranted.
