Age and Remission of Personality Pathology in the Psychotic Disorders Compared to Mood and/or Anxiety Disorders

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, but whether those PD traits in PSD patients or “odd, eccentric” PD traits in both groups seem to be maintained and less modified by aging.

Co-Morbidity of DSM-IV Personality Disorder in Major Depressive Disorder Among Psychiatric Outpatients in China: A Further Analysis of an Epidemiologic Survey in a Clinical Population

“…This has replicated the finding in previous studies such as the Australian National Survey of Mental Health and Wellbeing, which led to the conclusion that youths and not married individuals were also more likely to have PD (46–49). The effect of age on PD prevalence has been supported by some studies (36, 50) but rejected by others (46, 51, 52). Detailed discussion could be found in our former study (36).…”

Screening schizotypal personality disorder for detection of clinical high risk of psychosis in Chinese mental health services

“…1): the epidemiological survey of personality disorder (PD) was conducted at the Shanghai Mental Health Center in 2006. As detailed in previous papers (Zhang et al, 2012a(Zhang et al, , 2012b(Zhang et al, , 2012c(Zhang et al, , 2013 invitation letters were issued to outpatients using a systematic sampling method (i.e., select every 10th in psychotherapy and 20th in psychiatric clinics). The Personality Diagnostic Questionnaire Fourth Edition Plus (PDQ-4 þ) was used as screening tool for PD assessment, which included subscales of PDQ-SPD questionnaires.…”
