Background: While interpersonal sensitivity, as rated by the Interpersonal Sensitivity Measure (IPSM) has previously been found to be an efficient predictor of depression, there has been less interest in the relationship between the IPSM and anxiety disorders. This study examines the performance of the IPSM in discriminating between cases and non-cases of the various anxiety disorders. The contribution of depression and the perception of parental environment, to any relationships found, are also examined.
Methods: A cohort of 156 men and women has been assessed at 5-yearly intervals since baseline in 1978, in their last year of teacher training. In this fourth wave of follow-up, subjects completed a series of self-report questionnaires, including the IPSM, and scales measuring neuroticism and trait depression. Perceived parental environment, measured at baseline, was also included. DSM-III-R major depression and anxiety disorders were generated using the Composite International Diagnostic Interview. The IPSM subscales were moderately stable over time. 'Timidity' was associated with agoraphobia and simple phobia, and 'separation anxiety' with agoraphobia, panic disorder and generalised anxiety disorder. 'Separation anxiety' and 'timidity' showed differential gender effects for simple phobia. 'Fragile inner self' and 'separation anxiety' were associated with subjects with a history of repeated episodes of major depression, and the former, with perception of poor parental care.
Limitations: The IPSM was not available for inclusion prior to the 1988 wave.
Conclusions: While the IPSM subscales were consistently correlated with neuroticism, they displayed differential associations with specific anxiety disorders, episodes of major depression and early parental environment. These findings offer greater understanding of mechanisms concerning the relationship of vulnerability to anxiety disorders and depression.
