The association between the high interpersonal sensitivity type of personality and a lifetime history of depression in a sample of employed Japanese adults.
BACKGROUND
Although the 'high interpersonal sensitivity' type of personality has repeatedly been shown to be related to depression by case-control studies, no studies have confirmed whether this association also exists in a non-clinical sample.


METHODS
Scores on the Interpersonal Sensitivity Measure (IPSM) were compared between employed Japanese adults with and without a lifetime diagnosis of major depressive disorder. The diagnosis was provided by the Inventory to Diagnose Depression, Lifetime version. A multiple logistic regression analysis estimated the odds ratios for having a lifetime diagnosis of depression.


RESULTS
The scores on the IPSM were higher in the subjects with a lifetime history of depression than those without a lifetime history of depression. On the five subscales of the IPSM, the subjects with a lifetime history of depression showed higher scores on 'interpersonal awareness', 'need for approval', and 'separation anxiety' than those without a lifetime history of depression. The multiple logistic regression analysis showed that the subjects with the high interpersonal sensitivity type of personality had an increased risk for experiencing lifetime depression.


CONCLUSIONS
The results suggest that high interpersonal sensitivity is a risk factor for depression even in a non-clinical sample from non-Western culture.
