Posttraumatic stress disorder symptoms impact the emotional experience of intimacy during couple discussions

• Partners’ caring increased negative emotions for those with greater PTSD severity.
• Partners’ understanding and validation increased fear for those with PTSD.
• Provision of caring decreased anger, guilt, and sadness for those with PTSD.
• Treatments should consider the emotional impact of intimacy behaviors.

We examined the impact of PTSD symptom severity on emotional reactions to one's own and one's partner's intimacy behaviors. Heterosexual, community couples in which at least one partner reported elevated symptoms of PTSD were video-recorded discussing a relationship problem and self-reported their emotions immediately before and after the discussion. Each partner's intimacy behaviors were coded. Actor–Partner Interdependence Models indicate that, among those with greater PTSD symptom severity, partners’ caring, understanding, and validation were associated with increased negative emotions, particularly fear. Among those with greater PTSD severity, provision of caring was associated with decreased anger, guilt, and sadness. Therefore, the receipt of intimacy was associated with increased negative emotions among individuals with elevated PTSD symptoms while provision of intimacy was associated with decreased negative emotions. Existing treatments for PTSD should consider the emotional context of provision and receipt of intimacy to more fully address relationship problems among couples dealing with PTSD.
