The prestige model of spectrum bipolarity

Area of Science:

• Psychiatry and Behavioral Neuroscience
• Social Psychology
• Genetics

Background:

• Affective pathogenesis presents a significant challenge in psychiatry, necessitating novel causal models.
• The drive for social investment, specifically prestige, is explored as a potential factor in the bipolar spectrum.
• A seven-node bipolar spectrum is proposed, positing a gradient of "bipolarity" that may correlate with prestige motivation.

Purpose of the Study:

• To investigate the hypothesis that the drive for social prestige (leadership motivation) correlates with a proposed gradient of bipolarity.
• To test this hypothesis using a case-control study design.
• To examine differences in strategic prestige motivation between various nodes of the bipolar spectrum and controls.

Main Methods:

• A case-control study involving 228 subjects categorized into a seven-node bipolar spectrum.
• Statistical analysis controlling for mood elevation and depression to compare strategic prestige (leadership) motivation (MSPM) scores across spectrum groups.
• Correlation analysis between prestige motivation scores and dimensional lifetime bipolarity (Mood Disorder Questionnaire) scores.

Main Results:

• Bipolar I (S1) and Bipolar II (S2) spectrum nodes exhibited significantly higher strategic prestige (leadership) motivation scores compared to controls (S7).
• The pseudounipolar (S3) node also showed a trend towards elevated MSPM compared to controls, with notable mean differences and effect sizes.
• Prestige motivation scores positively correlated with lifetime bipolarity, supporting the proposed spectrum gradient, and were predicted by sensitivity to social inclusion, contingency of self-worth, and tension.

Conclusions:

• The findings provide preliminary support for a prestige model of bipolar spectrum disorder, suggesting a link between the drive for social investment and bipolarity.
• Evidence indicates a potential genetic predisposition towards elevated strategic prestige (leadership) motivation in bipolar disorders.
• Vulnerability of the social self, as indicated by sensitivity to social inclusion and self-worth contingency, may be a key feature in bipolar disorders.
