Problem-solving therapy versus supportive psychotherapy for Veterans with moderate suicide risk and chronic pain: A...

Individuals with chronic pain have increased risk of suicide, however, few receive suicide prevention interventions. Problem-solving therapy is an evidence-based treatment for chronic pain that seeks to improve problem-solving ability, an executive function associated with suicide risk and related outcomes. The goal of this pilot randomized controlled trial was to estimate if problem-solving therapy improves problem-solving ability and other outcomes for Veterans with chronic pain and moderate suicide risk (n = 44). Veterans were randomized to receive 12-weeks of video delivered problem-solving therapy or supportive psychotherapy. At post-treatment, problem-solving therapy was estimated to result in a greater increase in problem-solving ability (Cohen's d = 0.33, small effect) and a greater reduction in perceived burdensomeness (Cohen's d = 0.60, large effect), compared to supportive psychotherapy. These between-group differences were estimated to be maintained for problem-solving ability (Cohen's d = 0.94, large effect) and perceived burdensomeness (Cohen's d = 0.45, medium effect) at 6-month follow-up. It was estimated that problem-solving therapy did not have a differential effect on thwarted belongingness compared to supportive psychotherapy. In exploratory analysis, problem-solving therapy was estimated to reduce suicide ideation intensity, suicide ideation frequency, and suicide coping at post-treatment, however, in between-group analysis, only suicide ideation frequency was estimated to be reduced as compared to supportive psychotherapy. Results for the exploratory pain outcomes were mixed. This study suggests problem-solving therapy may improve problem-solving ability and reduce feelings of perceived burdensomeness. A fully powered clinical trial is needed to confirm these results and to determine if problem-solving therapy reduces suicide risk and improves pain outcomes.
