Personality is considered as an important aspect in persons with psychotic disorders. Several studies have investigated personality in schizophrenia. However, no study has investigated stability of personality traits exceeding three years in patients with schizophrenia. This study aims to investigate the stability of personality traits over a five-year period among patients with schizophrenia and non-psychotic individuals and to evaluate case-control differences.
Patients with psychotic disorders (n = 36) and non-psychotic individuals (n = 76) completed Swedish universities Scales of Personality (SSP) at two occasions five years apart. SSP scores were analysed for effect of time and case-control differences by multiple analysis of covariance (MANCOVA) and within-subjects correlation.
MANCOVA within-subjects analysis did not show any effect of time. Thus, SSP mean scale scores did not significantly vary during the five-year interval. Within subject correlations (Spearman) ranged 0.30-0.68 and 0.54-0.75 for the different SSP scales in patients and controls, respectively. Patients scored higher than controls in SSP scales Somatic Trait Anxiety, Psychic Trait Anxiety, Stress Susceptibility, Lack of Assertiveness, Detachment, Embitterment, and Mistrust.
The stability of the SSP personality trait was reasonably high among patients with psychotic disorder, although lower than among non-psychotic individuals, which is in accordance with previous research.
人格被认为是精神病患者的一个重要方面。有几项研究调查了精神分裂症患者的人格。然而，尚无研究调查精神分裂症患者的人格特质在三年以上的稳定性。本研究旨在调查精神分裂症患者和非精神病个体的人格特质在五年期间的稳定性，并评估病例对照差异。
36 名精神障碍患者（n=36）和 76 名非精神病个体（n=76）在相隔五年的两个时间点完成了瑞典大学人格量表（SSP）。通过多元协方差分析（MANCOVA）和被试内相关对 SSP 评分进行时间和病例对照差异的分析。
MANCOVA 被试内分析未显示时间的任何影响。因此，在五年的间隔内，SSP 平均量表评分没有显著变化。在患者和对照组中，不同 SSP 量表的被试内相关性（Spearman）分别为 0.30-0.68 和 0.54-0.75。患者在 SSP 量表的躯体特质焦虑、精神特质焦虑、应激易感性、缺乏自信、冷漠、怨恨和不信任方面的得分高于对照组。
尽管低于非精神病个体，但精神障碍患者的 SSP 人格特质稳定性相当高，这与之前的研究一致。
