OBJECTIVE: We know little about how change unfolds in depression symptoms during posttraumatic stress disorder (PTSD) treatment or how patient characteristics predict depression symptom change. This study examined critical transition points in depression symptoms during PTSD treatment, namely, depression sudden gains, which are rapid symptom improvements and transient depression spikes, which are transient depression worsenings. Social support, one of the strongest predictors of PTSD development, was examined as a predictor of depression symptom discontinuities. METHOD: At pretreatment, 200 participants (76.6% female; 64.9% Caucasian; age M = 37.1, SD = 11.3 years) completed measures of PTSD severity (PTSD Symptom Scale-Self-Report), depression severity (Beck Depression Inventory), general social support (Inventory of Socially Supportive Behaviors; Social Support Questionnaire), and trauma-related social support (Social Reactions Questionnaire). During 10 weeks of prolonged exposure (PE) or sertraline, depression was assessed weekly. RESULTS: Overall, 18.0% of participants experienced a depression sudden gain, and 22.5% experienced a transient depression spike. The presence of a depression sudden gain predicted better treatment outcome, β = -4.82, SE = 1.17, p = .001, 95% CI [-6.79, -2.90]. Higher perceptions of negative trauma-related reactions, albeit modestly, were associated with experiencing a transient depression spike (r = .18, p = .01). There were no differences in rates of depression sudden gains or transient depression spikes between treatments. CONCLUSIONS: Encouragingly, rapid improvements in depression symptoms are beneficial for PTSD treatment outcome, but transient spikes in depressive symptoms do not strongly influence outcome. Understanding symptom discontinuities may help us to personalize current PTSD treatment options. PsycINFO Database Record (c) 2014 APA, all rights reserved.
