This article describes the 19-item Social Comparison Motive Scale [SCMS], a measure of adolescents' motives for social comparison related to pregnancy. Dimensions and items were developed based on adolescent focus groups. The instrument was reviewed for content validity, pilot tested, and administered to 431 adolescents aged 14-18 years. Principal axis factor analysis with oblique rotation supported five dimensions. Convergent and discriminant validity were demonstrated by moderate correlations (r = .50) between the SCMS and the Iowa-Netherlands Comparison Orientation Measure and low correlations (r = .15) between the SCMS and the Rosenberg Self-Esteem Scale. Cronbach's alphas were .91 overall and .71 to .85 for the subscales. The SCMS demonstrated reliability and validity as a measure of adolescents' motives for comparing themselves with others about pregnancy.
本文介绍了包含19个条目的社会比较动机量表[SCMS]，这是一种用于测量青少年与怀孕相关的社会比较动机的工具。量表的维度和条目是基于青少年焦点小组开发的。该工具经过了内容效度审查、预测试，并施测于431名14至18岁的青少年。采用斜交旋转的主轴因子分析支持五个维度。SCMS与爱荷华-荷兰比较取向量表之间的中度相关性（r = 0.50）以及SCMS与罗森伯格自尊量表之间的低相关性（r = 0.15）证明了其收敛效度和区分效度。总量表的克朗巴哈系数为0.91，各分量表的克朗巴哈系数在0.71至0.85之间。作为一种测量青少年在怀孕方面与他人进行比较的动机的工具，SCMS表现出了信度和效度。
