Extended follow-up of a comprehensive behavioral (ComB) treatment sample during the COVID-19 pandemic

Association between the COVID-19 pandemic and psychiatric symptoms in people with preexisting obsessive-compulsive, eating, anxiety, and mood disorders: a systematic review and meta-analysis of before-after studies

AIM

To determine whether the coronavirus disease 2019 (COVID-19) pandemic was associated with a change in psychiatric symptoms in people with preexisting obsessive-compulsive, eating, anxiety, and mood disorders compared to their prepandemic levels.

METHODS

We searched MEDLINE, CINAHL, PsycINFO, and Embase from inception until February 16, 2022. Studies were included if they reported prepandemic and during-pandemic psychiatric symptoms, using validated scales, in people with preexisting mood, anxiety, eating, or obsessive-compulsive disorders. Two reviewers independently screened studies, extracted data, and assessed evidence certainty. Random-effects meta-analyses were conducted. Effect sizes were reported as standardized mean differences (SMDs) with 95% confidence intervals (CIs).

RESULTS

Eighteen studies from 10 countries were included. Of the 4465 included participants, 68% were female and the average age was 43 years. Mood and obsessive-compulsive disorders were the most studied disorders. During-pandemic psychiatric measurements were usually collected during nationwide lockdown. Obsessive-compulsive symptoms worsened among people with obsessive-compulsive and related disorders, with a moderate effect size (N = 474 [six studies], SMD = -0.45 [95% CI, -0.82 to -0.08], I2  = 83%; very low certainty). We found a small association between the COVID-19 pandemic and reduced anxiety symptoms in people with mood, anxiety, obsessive-compulsive, and eating disorders (N = 3738 [six studies], SMD = 0.11 [95% CI, 0.02-0.19], I2  = 63%; very low certainty). No change in loneliness, depressive, or problematic eating symptoms was found.

CONCLUSION

People with obsessive-compulsive and related disorders may benefit from additional monitoring during the COVID-19 pandemic and possibly future pandemics. Other psychiatric symptoms were stable in people with the specific disorders studied. Overall, evidence certainty was very low.

Comprehensive Behavioral Treatment of an Older Adult Man with Trichotillomania

The Comprehensive Behavioral (ComB) model of treatment for trichotillomania (TTM) and other body-focused repetitive behaviors offers a framework for individualized, flexible intervention based on functional analysis. This case report focuses on the treatment of a patient who enrolled in the first randomized clinical trial of ComB for TTM (Carlson et al., 2021) as well as a long-term follow-up of participants from that trial conducted during the COVID-19 pandemic (Flannery et al., in press). Walter (pseudonym) entered the treatment trial at 69, having had TTM since age 17 but not received treatment for it. Walter showed clinically significant improvement in treatment, ultimately abstaining from hair pulling for two years. A single case from a parallel-groups trial cannot support strong conclusions about why his results were favorable, but qualitative review of Walter’s experience in therapy suggested that allowing him a good deal of collaborative input on the specific methods of implementation of ComB principles was helpful. Along with the general literature on patient age as a predictor of therapy outcome, Walter’s case serves as a reminder that older adults, even those with highly chronic clinical conditions, can benefit greatly from psychotherapy.
