Sense of coherence in bipolar disorder- a longitudinal study

Area of Science:

• Psychiatry
• Psychology
• Longitudinal Studies

Background:

• Sense of Coherence (SOC) is crucial for perceiving life as comprehensible, manageable, and meaningful.
• Low SOC is linked to psychiatric disorders, but its role in bipolar disorder is not well-defined.
• This study investigates SOC in bipolar disorder patients over 14 years.

Purpose of the Study:

• To compare SOC levels between individuals with bipolar disorder and healthy controls.
• To examine the association of SOC with clinical characteristics and its long-term stability.
• To assess the predictive value of SOC for bipolar disorder outcomes.

Main Methods:

• 248 individuals with bipolar disorder and 113 controls were assessed using Antonovsky's SOC scale over 14 years.
• Clinical data included depression, disability, and comorbid diagnoses.
• Predictive value for relapse, suicide attempts, and self-harm was analyzed over a 7-year follow-up.

Main Results:

• Bipolar disorder patients exhibited significantly lower SOC than controls (p < 0.001).
• Lower SOC correlated with increased functional impairment, residual depression, and anxiety disorders.
• SOC remained stable over 14 years, with a slight increase in both groups. Baseline SOC predicted self-harm (p = 0.012) but not relapse or suicide attempts.

Conclusions:

• Lower SOC in bipolar disorder may reflect broader psychopathology rather than core illness symptoms.
• SOC's predictive value for self-harm suggests potential therapeutic targets for comorbid conditions.
• Interventions targeting SOC are unlikely to directly impact core bipolar disorder outcomes but may benefit associated issues.
