title: A Daily Diary Study of Posttraumatic Stress Symptoms and Romantic Partner Accommodation.
abstract: Little is known about the role of romantic partner symptom accommodation in PTSD symptom maintenance. To explore the bidirectional associations of posttraumatic stress disorder (PTSD) symptoms and romantic partner symptom accommodation over time, military servicemen (n=64) with symptoms of PTSD and their cohabiting heterosexual civilian romantic partners (n=64) completed a 2-week daily diary study. Cross-lagged, autoregressive models assessed the stability of men's PTSD symptoms and partners' accommodation, as well as the prospective associations of earlier PTSD symptoms with later accommodation and vice versa. Analyses used Bayesian estimation to provide point estimates (b) and Credible Intervals (CIs). In all models, PTSD symptoms (total and individual clusters) were highly stable (b=0.91; CI: 0.88-0.95), and accommodation was moderately stable (b=0.48; CI: 0.40-0.54). In all models, earlier PTSD symptoms (total and clusters) were significantly, positively associated with later accommodation (b=0.04; CI: 0.02-0.07). In contrast, earlier accommodation was significantly associated only with later situational avoidance (b=0.02; CI: 0.00-0.07). Thus, PTSD symptoms may lead to subsequent accommodating behaviors in romantic partners, but partner accommodation seems to contribute only to survivors' future situational avoidance symptoms. The findings reinforce the notion that PTSD symptoms have an impact on relationship behaviors, and that accommodation from partners may sustain avoidant behaviors in particular. Clinicians should attend to romantic partners' accommodating behaviors when working with survivors.
