The Effects of Temperament and Character on Symptoms of Depression in a Chinese Nonclinical Population

Abstract EN

Objective.

To examine the relations between personality traits and syndromes of depression in a nonclinical Chinese population.

Method.

We recruited 469 nonclinical participants in China.

They completed the Chinese version temperament and character inventory (TCI) and self-rating depression scale (SDS).

A structural equation model was used to rate the relation between seven TCI scales and the three SDS subscale scores (based on Shafer's meta-analysis of the SDS items factor analyses).

This was based on the assumption that the three depression subscales would be predicted by the temperament and character subscales, whereas the character subscales would be predicted by the temperament subscales.

Results.

The positive symptoms scores were predicted by low self-directedness (SD), cooperativeness (C), reward dependence (RD), and persistence (P) as well as older age.

The negative symptoms scores were predicted only by an older age.

The somatic symptoms scores were predicted by high SD.

Conclusion.

Syndromes of depression are differentially associated with temperament and character patterns.

It was mainly the positive symptoms scores that were predicted by the TCI scores.

The effects of harm avoidance (HA) on the positive symptoms scores could be mediated by low SD and C.
