Abstract

This study was designed to check the psychometric properties of an online Catalan version of the Type D Personality Scale-14 (DS14). Participants were 600 subjects including university professors, service and administrative personnel (n = 419) and students (n = 181); in total 196 men (32.7%) and 404 women (67.3%) with a mean age of 36.99 (SD = 12.76). The sample was randomly split in two groups: calibration and validation. The structural validity was analyzed in the calibration group (n = 311) using exploratory factor analysis with oblique and orthogonal rotation procedures, showing two robust factor structure, corresponding to Negative Affectivity (NA) and Social Inhibition (SI). No differences were found comparing the two rotation methods. Confirmatory factor analysis was performed in the validation group (n = 289) and the two factor model was replicated, showing satisfactory goodness-of-fit indices as χ²/df = 2.40, RMSEA = 0.07, SRMR = 0.06, GFI = 0.92, TLI = 0.93, CFI = 0.93 and IFI = 0.94. The re-specified model correlating the error terms of four pairs of items mildly improved goodness-of-fit indexes. The Catalan DS14 obtained a satisfactory internal consistency for its two subscales NA and SI (Cronbach's alpha = 0.85/0.88), and demonstrates good psychometric properties, being a suitable instrument for use in research in the Catalan population.

加泰罗尼亚版DS14量表评定d型人格的心理测量特性

本研究旨在检查在线加泰罗尼亚版D型人格量表-14 (DS14)的心理测量特性。受试者为600名，包括大学教授、服务人员和行政人员(n = 419)和学生(n = 181);男性196例(32.7%)，女性404例(67.3%)，平均年龄36.99岁(SD = 12.76)。样本随机分为两组:校准组和验证组。校正组(n = 311)采用倾斜和正交旋转的探索性因子分析进行结构效度分析，显示出负性情感(Negative affective, NA)和社会抑制(Social Inhibition, SI)两个稳健的因子结构。两种旋转方法比较无差异。验证组(n = 289)进行验证性因子分析，对两因素模型进行重复，拟合优度指标χ2/df = 2.40, RMSEA = 0.07, SRMR = 0.06, GFI = 0.92, TLI = 0.93, CFI = 0.93, IFI = 0.94。重新指定的模型将四对项目的误差项关联起来，适度提高了拟合优度指数。加泰罗尼亚人DS14的两个子量表NA和SI具有令人满意的内部一致性(Cronbach’s alpha = 0.85/0.88)，具有良好的心理测量特性，适合用于加泰罗尼亚人群的研究。

期刊介绍： The Anuario de Psicología, one of Spain"s most important general psychology journals, is published by the Faculty of Psychology of the University of Barcelona. It appears three times a year. The Anuario combines continuity with the past with a strong commitment to the present and the future. The journal is broad-ranging, interdisciplinary, and innovative. The Anuario publishes research reports and applied studies in all fields of psychology. We also accept theorical, epistemological studies, organize dossiers on topical themes, and hold debates on controversial subjects deriving from a central article.
