Effectiveness of stress control large group psychoeducation for anxiety and depression: Systematic review and meta-analysis

OBJECTIVES

This review sought to evaluate the effectiveness of the 'Stress Control' (SC) large psychoeducational 6-session group programme developed to increase access to treatment for patients with anxiety and depression.

DESIGN

Systematic review and meta-analysis (Prospero registration: CRD42020173676).

METHODS

Pre-post and post-treatment follow-up effect sizes were extracted and synthesized in a random effects meta-analysis, and variations in effect sizes were investigated via moderator analyses. Secondary analyses synthesized between-group effect sizes from controlled studies containing comparator treatments and calculated the average dropout rate. The quality of the meta-analysis was assessed using the GRADE approach.

RESULTS

Nineteen studies with pre-post treatment outcomes were included. The average group size was N = 39, and the average dropout rate was 34%. Pooled effect sizes indicated moderate pre-post treatment reductions in anxiety (ES = 0.58; CI 0.41 to 0.75; N = 5597; Z = 7.13; p < .001), moderate reductions in depression (ES = 0.62; CI 0.44 to 0.80; N = 5538, Z = 7.30; p < .001), and large reductions in global distress (ES = 0.86; CI 0.61 to 1.11; N = 591; Z = 7.41; p < .001). At follow-up, improvements in anxiety, depression, and global distress were maintained. When SC was compared to active and passive controls, outcomes were equivalent for anxiety (ES = 0.12, 95% CI -0.25 to 0.49, Z = -0.70; p = .482) and depression (ES = 0.15, 95% CI -0.24 to 0.54, Z = 0.84; p = .401).

CONCLUSIONS

SC appears to be a clinically effective and durable low-intensity group intervention that facilitates access to treatment for large patient numbers. However, conclusions are limited by the low methodological quality of the evidence.

PRACTITIONER POINTS

The stress control version of large group psychoeducation is appropriate and effective for mild-to-moderate anxiety and depression The evidence base for stress control is predominantly made up of practice-based studies Stress control needs to form one component of the overall offer made to patients presenting with mild-to-moderate anxiety and depression The competencies required to deliver such groups need better specification.

The Take Control Course: Conceptual Rationale for the Development of a Transdiagnostic Group for Common Mental Health Problems

BACKGROUND

Increasingly, research supports the utility of a transdiagnostic understanding of psychopathology. However, there is no consensus regarding the theoretical approach that best explains this. Transdiagnostic interventions can offer service delivery advantages; this is explored in the current review, focusing on group modalities and primary care settings.

OBJECTIVE

This review seeks to explore whether a Perceptual Control Theory (PCT) explanation of psychopathology across disorders is a valid one. Further, this review illustrates the process of developing a novel transdiagnostic intervention (Take Control Course; TCC) from a PCT theory of functioning.

METHOD

Narrative review.

RESULTS AND CONCLUSIONS

Considerable evidence supports key tenets of PCT. Further, PCT offers a novel perspective regarding the mechanisms by which a number of familiar techniques, such as exposure and awareness, are effective. However, additional research is required to directly test the relative contribution of some PCT mechanisms predicted to underlie psychopathology. Directions for future research are considered.

Efficacy of psychoeducation and relaxation interventions on stress-related variables in people with mental disorders: a literature review

This paper aimed to critically review and summarize empirical evidence concerning the efficacy of psychoeducation or relaxation-based stress management interventions on stress-related variables in people with mental disorders. Electronic databases were used during the literature search. Thirteen articles that fulfilled the preset eligible criteria were included in the review. Findings indicated that psychoeducation and relaxation-based interventions mitigated stress and depression; and enhanced relaxation intensity and knowledge on stress management. However, mixed results were obtained on anxiety. In addition, interventions using virtual reality technology revealed positive effects on depression, relaxation intensity and anxiety. Limitations and recommendations for future research are discussed.
