Improving memory for the content of therapy sessions might increase the effects of psychological interventions. Previous studies showed that healthy individuals who took a memory test (retrieval) of studied material showed better long-term memory retention than individuals who restudied (rehearsal) the material. The aim of the current study was to find out whether we can translate these findings to a subclinical setting. Individuals with moderate levels of distress were randomized into retrieving (n = 46) or rehearsing (n = 49) four weekly sessions of online Problem-Solving Therapy (PST). Session recall, problem-solving skills and distress were measured at baseline, three days after each session and at one-week follow-up. Retrieval led to overall higher recall, but this difference disappeared when controlling for the time spent on retrieval versus rehearsal. Retrieval did not lead to better problem-solving skills or less distress, compared to rehearsal. Baseline working memory performance moderated the effect of condition on recall after controlling for the time spent on retrieval versus rehearsal: the effect of retrieval compared to rehearsal on recall was larger for individuals with lower working memory performance. The sample mostly consisted of university students with overall high working memory scores. This study provided the first evidence that retrieval of the content of PST sessions may lead to better session recall compared to rehearsal of the PST sessions in individuals with a low working memory score. Implications for the use of cognitive support strategies within a therapeutic setting are discussed. •Psychological treatments might be improved if they increase patients' memory for treatment.•Distressed individuals retrieved or rehearsed sessions of problem-solving therapy.•Retrieval led to better overall recall of session content in individuals with lower working memory scores.
