The relationship between interpersonal sensitivity, anxiety disorders and major depression

Area of Science:

• Psychology
• Psychiatry
• Clinical Psychology

Background:

• Interpersonal sensitivity, measured by the Interpersonal Sensitivity Measure (IPSM), is a known predictor of depression.
• Less research has explored the IPSM's relationship with anxiety disorders.
• This study investigates the IPSM's ability to differentiate anxiety disorder cases from non-cases.

Purpose of the Study:

• To assess the Interpersonal Sensitivity Measure (IPSM) in distinguishing between individuals with and without various anxiety disorders.
• To examine the roles of depression and perceived parental environment in these associations.
• To explore the performance of IPSM subscales in relation to anxiety disorders.

Main Methods:

• A longitudinal cohort of 156 adults, assessed since 1978, completed questionnaires including the IPSM, neuroticism, and depression scales in their fourth follow-up wave.
• Diagnostic interviews (Composite International Diagnostic Interview) were used to identify DSM-III-R major depression and anxiety disorders.
• Perceived parental environment data from baseline was also analyzed.

Main Results:

• IPSM subscales demonstrated moderate temporal stability.
• 'Timidity' correlated with agoraphobia and simple phobia; 'separation anxiety' linked to agoraphobia, panic disorder, and generalized anxiety disorder.
• 'Separation anxiety' and 'timidity' showed gender-specific effects for simple phobia, while 'fragile inner self' and 'separation anxiety' were associated with recurrent major depression and perceived poor parental care.

Conclusions:

• IPSM subscales exhibited varied associations with specific anxiety disorders, major depression episodes, and early parental environment.
• These findings enhance understanding of the mechanisms underlying vulnerability to anxiety disorders and depression.
• The IPSM subscales were consistently correlated with neuroticism.
