Abstract

本研究的目的是在香港中学生人群中检验中文版本《原因知觉量表》(perceived locus of causality scale)在体育课中应用的相关心理测量学属性。两组香港中学生(样本1为346人,样本2为332人)被邀请完成原因知觉量表。来自两个样本的验证性因素分析结果支持原因知觉量表的五因素结构。条目7(外部调节)和条目3(内摄调节)均表现出跨因素以及与其他条目显著相关的现象。因此,删除条目7和条目3显著改善模型拟合情况。区分效度分析发现,认同调节和内部动机相关过高,可能存在无法区分情况。研究者进一步对五因素模型和四因素模型(将认同调节因素和内部动机因素合为一个因素)进行比较发现,四因素模型并不优于五因素模型。虽然两维度存在高相关,但五因素模型予以保留。15条目五因素原因知觉量表各分量表内部一致性信度,除内摄调节因素外均大于0.70。同时,恒等性分析结果表明,15条目五因素模型具有跨性别和跨组别的测量恒等性。潜变量平均数差异检验结果表明,来自两个样本的中学生在五个因素上得分均无显著差异;但女生在无动机、外部调节和内摄调节三个因素上的得分显著低于男生。本研究结果为原因知觉量表的信、效度提供了初步支持,该量表可以在香港中学生体育课情境中使用。但需要注意的是,认同调节和内部动机两个分量表的区别不明显,未来研究可进一步对这两个分量表进行调整及修订。 The purpose of the current study was to verify the psychometric properties of Chinese version 《Perceived Locus of Causality Scale》(PLOC)for implementing physical education class of Chinese junior secondary school students in Hong Kong. Two groups of the students(1n = 346;2n =332)were invited to answer the Chinese version PLOC. The results of confirmatory factor analysis(CFA)suggested that the five-factor structure model were replicated among the two groups. However,items 3and 7 of PLOC were found to be cross-factor and had high standardized residual covariance;and the fit of model improved significantly in both groups after removing the two items. These results provided support for the 15-item five-factor measurement model. Discrimination validity analysis showed that there was difficulty to differentiate identified regulation and intrinsic motivation due to high correlation between the two items. Further comparison between the five-factor structure model and the alternative four-factor structure model(combining identified regulation and intrinsic motivation into one) suggested that there was no advantage of alternative model over the five factor model,and thus the latter should be reserved. Composite reliability values of all subscales except for introjection subscale of regulation were larger than 0.70,supporting the reliability of PLOC subscales. The across-group and across-gender measurement invariance was evidenced in the 15-item 5-factor model. Latent mean difference analysis suggested that there were no difference in the scores of the 5 factors between the groups n1 and n2,however the scores of amotivation,external regulation and introjected regulation in girls were much lower than in boys. The current study provided initial psychometric evidence for the Chinese version PLOC in physical education class of Chinese junior secondary school students in Hong Kong.
