Posttraumatic stress disorder and social support in female victims of sexual assault: the impact of spousal involvement on the efficacy of cognitive-behavioral therapy.

Billette et al. (2008) worked with three women who had PTSD after sexual assault. Each woman got the same CBT, but her spouse joined every session.

The team used a multiple-baseline design. They staggered when therapy started for each couple. This let them see if changes happened because of treatment, not just time.

All three women lost their PTSD diagnosis by the end. They also said their spouse now gave more support.

Gains held at follow-up. The couples kept using the skills at home.

Christian et al. (1997) tried spouse-aided CBT first, but for depression. They found adding the spouse worked as well as solo therapy. Valérie et al. took the same idea and aimed it at PTSD eleven years later.

Walley et al. (2005) added social-skills training to exposure for combat vets. Valérie et al. swapped the skills group for a live spouse. Both studies show that a social piece can boost CBT for chronic PTSD.

Last et al. (1984) tested CBT parts for agoraphobia and saw no extra gain when they tacked on cognitive work. Valérie et al. show the opposite: adding the spouse did help. The gap likely lies in the problem (agoraphobia vs PTSD) and in the add-on (cognitive lessons vs spouse support).

If you treat adults with PTSD, invite the partner. One simple move—letting the spouse sit in—can erase the diagnosis and lift perceived support. Ask the couple if they are open to joint sessions. Start with the same CBT you already use; just set an extra chair.
