METHOD: A total of 64 depressed Iranian perimenopausal women were randomly assigned to two formats of treatments; sixteen sessions of group CA-CBT and eight sessions of individual CA-CBT, as well as a waitlist control group. Depression and sexual satisfaction were measured using BDI-II and ENRICH, respectively, at T1 (pre-treatment), T2 (post-treatment) and T3 (follow-up).

RESULTS: Repeated measures ANOVA indicated that the women who underwent both group and individual CA-CBT had effectively reduced depression and increased sexual satisfaction between pre-treatment and post-treatment, and it was sustained after six months of follow-ups with large effect sizes of significant differences (p < 0.001), but the control group did not.

METHODS: We report 12-month post-treatment data from a single-blind, active-controlled trial (October 2017-August 2019) where 327 Myanmar refugees in Malaysia were assigned to either six sessions of IAT (n = 164) or cognitive behavioral treatment (CBT) (n = 163). Primary outcomes were posttraumatic stress disorder (PTSD), depression, anxiety, and persistent complex bereavement disorder (PCBD) symptom scores at treatment end and 12-month post-treatment. Secondary outcome was functional impairment.

RESULTS: 282 (86.2%) participants were retained at 12-month follow-up. For both groups, large treatment effects for common mental disorders (CMD) symptoms were maintained at 12-month post-treatment compared to baseline (d = 0.75-1.13). Although participants in IAT had greater symptom reductions and larger effect sizes than CBT participants for all CMDs at treatment end, there were no significant differences between treatment arms at 12-month post-treatment for PTSD [mean difference: -0.9, 95% CI (-2.5 to 0.6), p = 0.25], depression [mean difference: 0.1, 95% CI (-0.6 to 0.7), p = 0.89), anxiety [mean difference: -0.4, 95% CI (-1.4 to 0.6), p = 0.46], and PCBD [mean difference: -0.6, 95% CI (-3.1 to 1.9), p = 0.65]. CBT participants showed greater improvement in functioning than IAT participants at 12-month post-treatment [mean difference: -2.5, 95% CI (-4.7 to -0.3], p = 0.03]. No adverse effects were recorded for either therapy.

DATA SOURCES: A systematic search using relevant keywords was conducted in PubMed-Medline, EMBASE, PsycINFO, CINAHL, Scopus, and The Cochrane Library.

INCLUSION CRITERIA: Randomized controlled trials (RCTs) that compared technology-based interventions with inactive controls in the treatment of moderate to severe dental anxiety were included.

RESULTS: A total of seven RCTs were included in the review. These studies investigated the effectiveness of video modeling, computerized cognitive behavioral therapy, virtual reality exposure therapy, and distraction with music and audiovisual video material. Six studies examining video modeling, computerized cognitive behavioral therapy, virtual reality exposure therapy, and distraction (audiovisual) showed significantly greater reductions in dental anxiety than inactive controls in both children and adults. None of the included studies followed Consolidated Standards of Reporting Trials guidelines completely or reported sufficient data, thereby precluding a possible meta-analysis. Four out of seven included studies were assessed to be at high risk of bias.

CONCLUSIONS: A limited number of studies supported the effectiveness of technology-based interventions in the treatment of dental anxiety in children and adults.

CLINICAL SIGNIFICANCE: The quality of the methods of studies on the effects of technology-based interventions allows only limited inferences on the effects of these interventions. However, within the limitations of the systematic review, the results converge to suggest that technology-based interventions may be useful as an adjunct to standard dental care. High-quality RCTs are needed to determine the (relative) effectiveness of these interventions.

METHODS: The study is being conducted as a randomized controlled intervention trial. Adult participants with unipolar depression are being randomized into three groups (BPT, MMT, or CG), and the first two groups are undergoing a 10-week treatment phase. CG follows their individual standard treatment as usual. A priori power analysis revealed that about 120 people should be included to capture a moderate effect. The primary outcome of the study is depression rated with the Montgomery and Asberg Depression Rating Scale (MADRS) before (t0), directly after (t1), and 12 months after the intervention phase (t2). Data are being collected via questionnaires, computer-assisted video interviews, and physical examinations. The primary hypotheses will be statistically analyzed by mixed model ANOVAs to compare the three groups over time. For secondary outcomes, further multivariate methods (e.g., mixed model ANOVAs and regression analyses) will be conducted. Qualitative data will be evaluated on the basis of the qualitative thematic analysis.

DISCUSSION: This study is investigating psychological and physical effects of BPT and MMT and its factors of influence on outpatients suffering from depression compared with a CG in a highly naturalistic design. The study could therefore provide insight into the modes of action of group therapy for depression and help to establish new short-term group treatments. Methodological limitations of the study might be the clinical heterogeneity of the sample and confounding effects due to simultaneous individual psychotherapy.
