易损性人格风格问卷(VPSQ)是一种由9个条目组成的自我报告人格问卷，用于识别因个性脆弱而产生产后抑郁症的高危女性。初步研究表明，该量表具有令人满意的心理测量学特性。这项方法学研究的目的是进一步检验VPSQ在加拿大女性样本中的心理测量学特性。作为纵向研究的一部分，妇女在产后1周、4周和8周完成邮寄问卷，其中包括VPSQ、爱丁堡产后抑郁量表、罗森堡自尊量表和感知压力量表。594名妇女返回了适合分析的问卷。VPSQ的Cronbach‘sα系数为0.67，VPSQ与自尊(r=0.58)和知觉压力(r=0.55)量表之间存在显著的相关，为结构效度提供了证据。在Logistic回归分析中，VPSQ是产后1.4周和8周发生抑郁症状的预测因素，VPSQ每增加1分，发生产后抑郁的风险增加1.3倍。这项研究的结果支持了VPSQ的整体效用。因此，这一简短的工具随时准备帮助确定有患产后抑郁症风险的妇女，以便可以启动适当的二级预防治疗干预措施。
The Vulnerability Personality Style Questionnaire (VPSQ), a 9-item self-report personality scale, was developed to identify women at-risk for postpartum depression due to personality vulnerability. Preliminary research with this scale suggests it has satisfactory psychometric properties. The purpose of this methodological study was to further examine the psychometric properties of the VPSQ in a sample of Canadian women. As part of a longitudinal study, women completed postal questionnaires at 1, 4, and 8 weeks postpartum that included the VPSQ, Edinburgh Postnatal Depression Scale, Rosenburg Self-Esteem Scale, and Perceived Stress Scale. Five hundred and ninety-four women returned questionnaires suitable for analysis. The Cronbach's alpha coefficient for the VPSQ was 0.67 and significant correlations between the VPSQ and self-esteem (r = 0.58) and perceived stress (r = 0.55) scales were found providing evidence for construct validity. In a logistic regression analysis, VPSQ was predictive of developing depressive symptomatology 1.4 and 8 weeks postpartum an increase of of one point on the VPSQ increased the risk of developing postpartum depression 1.3 fold. The results from this study support the overall utility of the VPSQ. As such, this brief instrument is ready to assist in the identification of women at risk of developing postpartum depression such that appropriate secondary preventive of treatment interventions may be initiated.
