Changes in self-schema structure in cognitive therapy for major depressive disorder: a randomized clinical trial

Area of Science:

• Psychology
• Clinical Psychology
• Psychiatry

Background:

• Negative cognitive structures can persist after depression, indicating vulnerability.
• Cognitive therapy (CT) effectively treats depression and reduces relapse risk.
• CT may alter stable cognitive structures linked to depression vulnerability.

Purpose of the Study:

• To investigate if cognitive therapy (CT) alters stable negative cognitive structures in depression.
• To compare the effects of CT plus pharmacotherapy versus pharmacotherapy alone on cognitive organization.

Main Methods:

• Randomized controlled trial with two groups: CT + pharmacotherapy (n=21) and pharmacotherapy alone (n=21).
• Assessed depression levels, automatic thoughts, dysfunctional attitudes, and cognitive organization.
• Utilized Beck Depression Inventory-II and Hamilton Rating Scale for Depression.

Main Results:

• Both groups showed similar reductions in depression, automatic thoughts, and dysfunctional attitudes.
• The CT + pharmacotherapy group demonstrated superior improvements in cognitive organization.
• No significant differences in depression severity reduction between groups.

Conclusions:

• Combining CT with pharmacotherapy may be more effective in altering cognitive organization than pharmacotherapy alone.
• CT might modify stable cognitive vulnerability markers for depression.
• Findings support the potential prophylactic role of CT in depression.
