The Self-Perception Profile for Adolescents (SPPA; Harter, 1988) was administered to a national representative sample of 11,315 Norwegian adolescents of the ages 13 to 20. The original version of SPPA has an idiosyncratic and time-consuming item format, describing two adolescents with opposite characteristics on each item. A revised version of SPPA was developed using only one statement for each item. The original SPPA was administered to a random subsample of 880 subjects, whereas the rest of the total sample completed the revised edition. Concerning the original SPPA, results showed low to adequate reliability and poor replication of the factorial pattern. However, low correlations with the Marlowe-Crowne Social Desirability Index were obtained, and the construct validity was supported. Concerning the revised edition, the a priori factorial pattern was replicated. Further, it had substantially better reliability, better convergent validity, and better factorial validity than the original version. The discriminant validity and the contamination by social desirability bias were the same for both versions. The data thus indicate that there is no need to retain the time-consuming and cumbersome item format of the original SPPA.
青少年自我认知量表(SPPA;哈特,1988年)被施用于11315名年龄在13至20岁的挪威青少年的全国代表性样本。SPPA的原始版本有一种独特且耗时的项目格式,每个项目描述两个具有相反特征的青少年。SPPA的修订版每个项目仅使用一条陈述来编制。原始的SPPA被施用于880名受试者的随机子样本,而总样本的其余部分完成了修订版。关于原始的SPPA,结果显示信度从低到尚可,且因子模式的可重复性较差。然而,与马洛-克劳恩社会赞许性指数的相关性较低,且结构效度得到了支持。关于修订版,先验因子模式得到了重复。此外,它的信度显著更好,聚合效度更好,且因子效度比原始版本更好。两个版本的区分效度和社会赞许性偏差的污染情况相同。因此,数据表明无需保留原始SPPA耗时且繁琐的项目格式。
