This study examined the psychometric properties of the Defense Style Questionnaire (DSQ-40) in adolescents. Internal consistency, factor structure, and discriminant and concurrent validity of the DSQ-40 were studied in 211 adolescent psychiatric outpatients aged 13 to 19 years and 199 age-matched and sex-matched controls. Principal components analysis yielded four internally consistent components: mature, neurotic, image-distorting, and immature defense styles. The outpatients reported more immature, image-distorting, and neurotic styles and less mature style than did the controls, suggesting adequate discriminant validity. As a demonstration of convergent and concurrent validity, the severity of psychiatric symptoms assessed by the General Health Questionnaire and psychosocial adjustment assessed by the Global Assessment of Functioning Scale correlated theoretically meaningfully with the different defense styles. The DSQ-40 appears to be a reliable and valid instrument for adolescents.
本研究考察了青少年防御方式问卷（DSQ - 40）的心理测量学特性。对211名年龄在13至19岁的青少年精神科门诊患者以及199名年龄和性别匹配的对照者，研究了DSQ - 40的内部一致性、因子结构、区分效度和同时效度。主成分分析产生了四个内部一致的成分：成熟防御方式、神经质防御方式、形象歪曲防御方式和不成熟防御方式。与对照组相比，门诊患者报告的不成熟、形象歪曲和神经质防御方式更多，而成熟防御方式更少，表明有足够的区分效度。作为聚合效度和同时效度的例证，由一般健康问卷评估的精神症状严重程度以及由功能总体评定量表评估的心理社会适应与不同防御方式在理论上有显著相关性。DSQ - 40似乎是一种适用于青少年的可靠且有效的工具。
