具有稳定行为特征的人格出现在青少年和青少年时期。假定不同的模型,但是相关的,人格特质已经发展到描述行为风格,包括分裂型,自恋,冷酷无情,负面情绪,反社会和冲动特征。这些特征影响了其相关人格障碍的分类。我们测试了双因素模型是否比相关因素和正交因素模型更好地拟合数据,随后用心理健康措施和治疗史验证了获得的因素。
从14至25岁(N=2443)的青少年和年轻人的志愿者社区样本中收集了一组自我报告问卷,用于测量上述特征以及心理健康和服务使用情况。
探索性分析中出现了具有一个一般因素和四个特定因素的双因素模型,比具有相关或正交因素的模型更好地拟合数据。一般因子具有较高的信度和效度。
研究结果表明,选定范围的假定独特的人格特质是由一般的潜在人格特质支撑的,该人格特质可以解释为严重程度因素。分数越高,社会功能受损越多。结果与ICD-11一致,ICD-11表明人格障碍与人际关系或社会功能受损之间存在明确的联系。获得的一般因素类似于DSM-5第III节提出的人格功能的总体维度(描述一个人与自我和他人的关系)。
Personality with stable behavioural traits emerges in the adolescent and young adult years. Models of putatively distinct, but correlated, personality traits have been developed to describe behavioural styles including schizotypal,
narcissistic, callous-unemotional, negative emotionality, antisocial and impulsivity traits. These traits have influenced the classification of their related personality disorders. We tested if a bifactor model fits the data better than correlated-factor and orthogonal-factor models and subsequently validated the obtained factors with mental health measures and treatment history.
A set of self-report questionnaires measuring the above traits together with measures of mental health and service use were collected from a volunteer community sample of adolescents and young adults aged 14 to 25 years (N = 2443).
The bifactor model with one general and four specific factors emerged in exploratory analysis, which fit data better than models with correlated or orthogonal factors. The general factor showed high reliability and validity.
The findings suggest that a selected range of putatively distinct personality traits is underpinned by a general latent personality trait that may be interpreted as a severity factor, with higher scores indexing more impairment in social functioning. The results are in line with ICD-11, which suggest an explicit link between personality disorders and compromised interpersonal or social function. The obtained general factor was akin to the overarching dimension of personality functioning (describing one\'s relation to the self and others) proposed by DSM-5 Section III.
