The Generalized Anxiety Disorder 7-item (GAD-7) scale is widely used for the assessment of generalized anxiety disorder.
To adapt the GAD-7 to the Chilean adolescent population and to evaluate its psychometric properties.
The GAD-7 was adapted and administered to 2,022 adolescents between 13 and 19 years of age, recruited from eight schools in the northern area of Santiago, Chile. Other self-report instruments were used to assess depressive symptoms and health-related quality of life. The one factor structure and invariance by sex were examined using Confirmatory Factor Analysis. Its reliability and validity based on its relationship with other variables were assessed.
The one-factor structure and invariance by sex were confirmed. The results showed an adequate internal reliability (Cronbach's alpha = 0.86, Spearman-Brown coefficient = 0.82). As expected, significant correlations were observed with measures of depressive symptoms and health-related quality of life. Higher scores were observed in women than in men.
The Chilean version adapted for adolescents of the GAD-7 has good psychometric properties. Thus, it may be a useful and valid instrument for the assessment of generalized anxiety disorder in adolescents in Chile.
广泛性焦虑障碍7项（GAD - 7）量表广泛用于广泛性焦虑障碍的评估。
使GAD - 7适用于智利青少年人群并评估其心理测量学特性。
对GAD - 7进行改编并施测于从智利圣地亚哥北部地区8所学校招募的2022名13至19岁青少年。使用其他自我报告工具评估抑郁症状和健康相关生活质量。采用验证性因素分析检验单因素结构和性别不变性。基于其与其他变量的关系评估其信度和效度。
确认了单因素结构和性别不变性。结果显示具有足够的内部信度（克朗巴哈α系数 = 0.86，斯皮尔曼 - 布朗系数 = 0.82）。正如预期的那样，观察到与抑郁症状测量和健康相关生活质量存在显著相关性。女性得分高于男性。
适用于智利青少年的GAD - 7版本具有良好的心理测量学特性。因此，它可能是评估智利青少年广泛性焦虑障碍的一种有用且有效的工具。
