Abstract

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. © 2019 Seyyed Mehdi Mirsharifa, Bahram Mirzaian, Yarali Dousti.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Group sizes conflict: 15 per group versus 30 total after 40 eligible

    Major

    The abstract says 30 patients were assigned into two groups of 15, while the Methods section says 40 patients met criteria and were assigned to intervention and control groups. The study cannot simultaneously have 30 and 40 randomized participants without explanation.

  • Different numbers of patients are said to have been assigned to groups

    Major

    The abstract says 30 patients were selected and assigned, 15 per group. The methods say 40 eligible patients were assigned to the groups; they do not describe a subsequent selection of 30 or explain the difference.

  • Pessimism is credited with opposite emotional effects

    Minor

    The discussion first says pessimism produces negative feelings, then says it expands positive feelings and emotions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read under definition version 3 (extract-v3) on 2026-09-28.
