Close significant others (CSOs) are vital sources of posttrauma social support, but may also engage in symptom accommodation that reinforces avoidance and exacerbates posttraumatic stress. Since accommodation can therefore resemble support, clarifying their relationship is essential.

This study investigated how accommodation of survivor anger and anxiety related to CSO appraisals of how frequently they offered support, and how hard they found it to give.

Close friends, family members and romantic partners (N = 351) of past-year trauma survivors completed a survey on posttrauma support provision experiences. A multivariate path model tested associations between anger and anxiety accommodation and social support, both overall and across specific subtypes (i.e., informational, tangible, emotional, esteem).

Anger accommodation was linked to less frequent support ( β  = -.21, 95% CI [-.34, -.09], p = .001) and greater support difficulty overall ( β  = .40, 95% CI [.27, .53], p < .001, and across tangible, emotional, and esteem subtypes. Anxiety accommodation was linked to more frequent support overall ( β =.35, 95% CI [.23, .46], p < .001), and across informational and tangible support subtypes, and with greater difficulty offering esteem support.

CSOs who accommodate survivor anger struggle more with support provision, while those who accommodate anxiety report offering more support. Distinguishing protective support from accommodation may help guide CSOs toward behavioral strategies that foster survivor recovery over avoidance, and promote relational wellbeing.
