BACKGROUND: Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders, worldwide. Psychological disorders are common among patients with IBS.

AIM: This study aims to investigate the efficacy of acceptance and commitment therapy (ACT) matrix on depression and psychological capital of patients with IBS.

MATERIAL AND METHODS: In a quasi-experimental study, a total number of 30 patients with IBS were selected using convenience sampling. Those patients who meet the inclusion criteria were randomly assigned to control and experimental groups (15 patients in each group). Data were collected using the Beck Depression Inventory (BDI) and the Psychological Capital Questionnaire (PCQ). The experimental group was subjected to the acceptance and commitment therapy (ACT) amtrix, but the control group do not receive this treatment. Questionnaires were completed before (pre-test) and after (post-test) the intervention by patients in two groups. All patients in two groups responded to the questionnaires and returned them to the researcher. Data were analyzed using chi-square test, independent t-test, analysis of covariance (ANCOVA) and multivariate analysis of covariance (MANCOVA).

RESULTS: Analyzing the data showed that there were significant differences regarding depression and psychological capital between experimental and control group, before and after the study (p < 0.05).

CONCLUSION: Using ACT matrix is a useful modality to improve the depression and psychological capital among patients with IBS.
