Randomized Controlled Trial
The Role of Social Support in Cognitive-Behavioral Conjoint Therapy for Posttraumatic Stress Disorder.
The current study examined the effect of total, as well as different sources (i.e., family, friends, significant other) of, pretreatment/baseline social support on posttraumatic stress disorder (PTSD) severity and treatment response to cognitive-behavioral conjoint therapy (CBCT) for PTSD. Thirty-six patients were randomized to receive treatment immediately or to a waitlist condition. Those in the treatment condition were offered CBCT for PTSD, a couple-based therapy aimed at reducing PTSD symptoms and improving relationship functioning. ⋯ Additionally, significant other social support moderated treatment outcomes, such that higher initial significant other support was associated with larger decreases in PTSD severity for those in the treatment condition (g = -1.14) but not the waitlist condition (g = -.04). Social support from a significant other may influence PTSD treatment outcomes within couple therapy for PTSD. The inclusion of intimate partners and other family members may be a fruitful avenue for improving PTSD treatment outcomes; however, future studies are needed to examine whether support can be increased with treatment and whether those improvements lead to greater PTSD symptom response.

Increasing evidence suggests that pain-related fear is key to the transition from acute to chronic pain. Previous research has shown that perceptual similarity with a pain-associated movement fosters the generalization of fear to novel movements. Perceptual generalization of pain-related fear is adaptive as it enables individuals to extrapolate the threat value of one movement to another without the necessity to learn anew. ⋯ During generalization, fear and expectancy generalized to novel exemplars of the CS+ category, but not to the CS- category. This pattern was not corroborated in the eyeblink startle measures. This is the first study that demonstrates that pain-related fear can be acquired and generalized based on conceptual knowledge.
