Heterogeneous depression responses to chronic pain onset among middle-aged adults: a prospective study.
Studies on depression response to chronic pain are limited by lack of clarification of different forms of response patterns and cross-sectional measures. The current study examined heterogeneous long-term patterns of depression response to chronic pain onset prospectively using the mixture modeling technique. Depression symptoms prior to and following pain onset over a course of six years were charted in a nationally representative middle-aged sample. ⋯ Self-rated health at both baseline and following pain onset predicted the resilience trajectory. Baseline self-rated health distinguished the post-pain depression and chronic depression trajectories. Individuals in the prior depression improved trajectory were older and had more chronic illnesses at baseline but fewer illnesses following pain onset, compared to those in the resilience or post-pain depression trajectory.

The impact of social support on psychological distress for U.S. Afghanistan/Iraq era veterans with PTSD and other psychiatric diagnoses.
This study aimed to examine the degree to which posttraumatic stress disorder (PTSD) affects the relationship between social support and psychological distress for U. S. Afghanistan/Iraq era veterans with and without co-occurring psychiatric disorders. ⋯ Furthermore, those with PTSD plus co-morbid diagnoses did not demonstrate significantly larger attenuation in that association compared to the PTSD-only group, indicating that psychiatric comorbidity may be less important in considering the role of social support in PTSD. By understanding this relationship, new avenues for engaging and enhancing treatment outcomes related to social support for veterans of this cohort may be identified. Additional longitudinal research could help evaluate the effect of PTSD symptom clusters, social support type, and trauma exposure type on these relationships.
