Abstract

OBJECTIVE: Posttraumatic stress disorder (PTSD) is a significant condition and frequently observed among breast cancer survivors. Extant literature has demonstrated the effectiveness of expressive writing interventions in reducing PTSD among breast cancer survivors. However, little is known about how different PTSD symptom clusters influence each other over time during and after the expressive writing intervention among breast cancer survivors. We investigated how the three PTSD symptom clusters (reexperiencing, avoidance and hyperarousal) influence each other during and after an expressive writing intervention among Chinese American breast cancer survivors.

METHODS: Chinese American breast cancer survivors (n = 136) completed an expressive writing intervention. Their PTSD symptoms were assessed at baseline, 1-, 3-, and 6-month follow-ups.

RESULTS: Using cross-lagged panel analysis, the model with hyperarousal symptoms at each assessment wave predicting the subsequent severity of avoidance and reexperiencing symptoms indicated the best fit, χ2(52) = 65.422, p = .100; CFI = 0.990, RMSEA = 0.044, 95% CI [0.000, 0.074].

CONCLUSION: The results suggest that hyperarousal symptoms predict the subsequent severity of reexperiencing and avoidance symptoms over time during and after the expressive writing intervention. The findings highlight the importance of early diagnosis, monitoring and treatment of hyperarousal symptoms in enhancing the efficacy of PTSD interventions and reducing the chronicity in PTSD among Chinese American breast cancer survivors.
