ABSTRACT: Previous Dependency Inventory (JIDI) as well
demonstrates how the interpersonal attitudes assessed by the JIDI generate
interpersonal negative life events (NLEs) and therefore results in dysphoric
moods and poor life functioning. The subjects of this study were 467 Japanese
university students. The JIDI was administered at Time 1, and the Clinical
Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) was administered at
Time 2 for the purpose of assessing dysphoric mood and life functioning. NLEs
occurring between Times 1 and 2 were evaluated. The three-factor structure of
the JIDI was confirmed by confirmatory factor analysis. The structural equation
modeling demonstrated that of the three factors, only one, “emotional reliance”,
predisposed individuals to dysphoric mood and poor life functioning, both directly
and indirectly, via interpersonal NLEs. Although the other two factors did not
increase vulnerability to interpersonal NLEs or dysphoric mood, “lack of social
self-confidence” worsened general functioning, and “assertion of autonomy” led
to poor functioning in close relationships, both directly. Furthermore,
“assertion of autonomy” decreased anxiety levels. As to gender differences,
simultaneous analysis of multi-groups showed that female subjects were more
likely to become anxious following interpersonal NLEs.
