Attributional style and depression in multiple sclerosis: the learned helplessness model.

Area of Science:

• Psychology
• Neuroscience
• Clinical Medicine

Background:

• Depression is common in multiple sclerosis (MS).
• Learned helplessness (LH) theory posits that attributing negative events to internal, stable, and global causes increases vulnerability to depression.
• Adapting LH theory for the MS population may clarify depression in this group.

Purpose of the Study:

• To test the reformulated LH theory in patients with MS.
• To differentiate between illness-related and non-illness-related attributions in MS.
• To examine the relationship between attributional style, stressors, disability, and depressive symptoms in MS.

Main Methods:

• 52 patients with MS completed measures of attributional style, daily stressors, disability, and depressive symptoms.
• Attributional Style Questionnaire (ASQ) was used to assess attributions for negative events.
• Statistical analyses examined correlations and mediation effects.

Main Results:

• Patients more frequently cited non-MS-related causes for negative events than MS-related causes.
• Higher disability in MS was associated with more MS-related attributions.
• Non-MS-related attributions correlated with stress and depressive symptoms.
• MS-related attributions did not correlate with disability or depressive symptoms.
• Stress mediated the relationship between non-MS-related attributions and depressive symptoms.

Conclusions:

• Attributional style is relevant in MS, but not directly linked to depressive symptoms.
• Non-illness-related attributions are associated with increased perceived stress, which in turn elevates depressive symptoms in MS.
• Findings suggest focusing on stress management related to non-illness attributions may be beneficial for reducing depression in MS.
