Detached mindfulness as a stand-alone intervention: a Systematic Review and meta-analysis.

Area of Science:

• Psychology
• Clinical Psychology
• Cognitive Behavioral Therapy

Background:

• Detached Mindfulness (DM) is a core technique in Metacognitive Therapy (MCT).
• DM enhances meta-awareness of intrusions and promotes disengagement from them.
• It targets the Cognitive Attentional Syndrome and dysfunctional metacognitive beliefs.

Purpose of the Study:

• To systematically review and meta-analyze the effects of Detached Mindfulness (DM) as a stand-alone intervention.
• To evaluate DM's efficacy beyond its typical integration within full Metacognitive Therapy (MCT) protocols.

Main Methods:

• Systematic review and meta-analysis of studies examining DM as a stand-alone intervention.
• Inclusion criteria: DM as a stand-alone intervention in clinical or non-clinical samples.
• Searches conducted in major databases; quality and risk of bias assessed.

Main Results:

• Fourteen studies with 256 participants (≥17 years) met inclusion criteria.
• Three clinical trials showed large symptom reductions (Hedges' g = -1.80 for primary outcomes).
• Eight of nine other samples reported beneficial effects, often medium-to-large in magnitude.

Conclusions:

• Detached Mindfulness (DM) shows promise as a stand-alone intervention for improving psychological symptoms.
• Findings support DM's transdiagnostic utility and potential for brief interventions.
• Limitations include small study numbers, methodological issues, and lack of long-term follow-up.
