Abstract

AIM: Considering the key role of human resources as the main operator of organisations, the present research aimed to determine the effectiveness of acceptance and commitment therapy for anxiety and depression of Razi Psychiatric Center staff. MATERIALS AND METHODS: This research follows a quasi-experimental type with pre-test, post-test plans, and control group. Accordingly, 30 people were selected through volunteered sampling among Razi Psychiatric Center staff. Then, they were randomly placed into two groups of 15 (experimental and control) and evaluated using research tools. Research tools consisted of Beck Anxiety and Depression Inventories whose reliability and validity have been confirmed in several studies. Research data were analysed using the analysis of covariance (ANCOVA). Results: The statistical analysis confirmed the difference in the components of anxiety and depression in the experimental group, which had received acceptance and commitment therapy compared to the group that had not received any therapy in this regard (control group) (p < 0.05). CONCLUSION: Acceptance and commitment therapy reduces anxiety and depression. © 2018 Mostafa Heydari, Saideh Masafi, Mehdi Jafari, Seyed Hassan Saadat, Shima Shahyad.

TL;DR

This quasi-experimental study tested acceptance and commitment therapy (ACT) among Razi Psychiatric Center staff and found significant reductions in anxiety and depression compared with a no-treatment control group. The authors conclude that ACT reduced both outcomes, with effects maintained at a two-month follow-up.

Key findings

  • Anxiety was significantly lower in the ACT group than the control group after controlling for pretest scores (p = 0.000, F = 119.955), and this difference remained at follow-up (p = 0.000, F = 81.072).
  • Depression was also significantly lower in the ACT group after controlling for pretest scores (p = 0.000, F = 152.302), with follow-up results remaining significant (p = 0.000, F = 30.413).
  • The abstract reports that the statistical analysis confirmed differences in anxiety and depression components between the experimental and control groups at p < 0.05.

Methods

  • The design was quasi-experimental with pretest, posttest, and control group. Thirty volunteers from Razi Psychiatric Center staff in 2015–16 were randomly assigned to two groups of 15; the experimental group received eight 90-minute ACT sessions, while the control group received no intervention.
  • Measures were the Beck Anxiety Inventory (21 items, scores 0–63) and the Beck Depression Inventory-II (21 items, scored 0–3 per item), with reliability and validity cited from prior studies.
  • Data were analyzed using analysis of covariance (ANCOVA), with pretest scores as covariates; the text notes that homogeneity of variances was outside criteria for some components, so an alpha of 0.025 was used.

Limitations

  • Stated by the authors: findings rely on self-report data, the sample size was small, and further studies with larger samples are recommended to clarify results and examine all aspects of ACT on anxiety and depression.
  • Evident from the text: the use of volunteer sampling and a quasi-experimental design limits generalizability and causal inference, and the control group received no intervention, with no blinding or treatment-fidelity procedures reported.

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.
