Group person-based cognitive therapy for chronic depression: a pilot randomized controlled trial

Area of Science:

• Psychiatry
• Clinical Psychology
• Mindfulness-Based Interventions

Background:

• Chronic depression presents a significant challenge in mental healthcare.
• Existing treatments for chronic depression have limitations in efficacy.
• Integrating cognitive therapy with mindfulness offers a novel therapeutic approach.

Purpose of the Study:

• To evaluate the efficacy of Person-Based Cognitive Therapy (PBCT) as a treatment for chronic depression.
• To assess the impact of PBCT on depression severity and mindfulness levels.
• To determine the feasibility of a larger randomized controlled trial (RCT).

Main Methods:

• A pilot randomized controlled trial (RCT) involving 28 participants with chronic depression.
• Participants were randomized to either treatment as usual (TAU) or PBCT plus TAU.
• Assessments included the Beck Depression Inventory (BDI-II) and Southampton Mindfulness Questionnaire, administered pre- and post-therapy.

Main Results:

• Significant group by time interactions were observed for both depression and mindfulness scores.
• PBCT participants demonstrated significant improvements in depression and mindfulness.
• 64% of PBCT participants achieved reliable improvement in depression, compared to 0% in the TAU group.

Conclusions:

• Person-Based Cognitive Therapy (PBCT) shows promise as an effective treatment for chronic depression.
• The findings support the need for a full-scale randomized controlled trial to further validate PBCT.
• PBCT may offer a valuable therapeutic option for individuals with persistent depressive symptoms.
