Age and remission of personality pathology in the psychotic disorders compared to mood and/or anxiety disorders

Tianhong Zhang et al. Int J Psychiatry Med. 2012.

Abstract

In order to explore age-related differences in personality pathology between psychotic disorder (PSD) and mood and/or anxiety disorder (MAD) among psychiatric outpatients, 2,354 subjects were sampled randomly from outpatients in Shanghai and divided into two groups: PSD (N = 951) and MAD (N = 1403). Dimensional scores for personality disorder (PD) traits were assessed by using a self-reported personality diagnostic questionnaire (PDQ4+). Significant age differences were observed in most of the PD traits in MAD patients. Cluster B and C PD traits displayed an apparent decrease with age in MAD group, but such decline trend was not evident in PSD group. In both groups, the decline of self-reported Cluster A PD traits were less visible than the other clusters. Age-related mellowing of some PD traits such as "dramatic, erratic, anxious" occurred primarily in MAD patients; however the same traits in PSD patients appear to be less resistant to aging. Besides, "old eccentric" PD traits in both MAD and PSD patients seem to be maintained and less modified by aging.

Cluster A PD traits and age Note, Percentile age groups: 0-10(18~21 years), 10-20(22~23 years), 20-30(24~25 years), 30-40(26~27 years), 40-50(28~30 years), 50-60(31~33 years), 60-70(34~37 years), 70-80(38~42 years), 80-90(43~48 years), 90-100(49~60 years). The trend can be seen directly through the distribution of points or with the addition of a linear trend line (Excel provides the trendline equation and R-squared value in the chart.).
