大學男女新生在健康促進生活型態測量恆等性之研究

A Study of Measurement Invariance on HPLP: An Example of the Freshmen in One University

本研究探討大學男女新生在「健康促進生活型態量表」的測量恆等性檢定，了解健康促進生活型態是否具有跨群體的信、效度，檢定健康促進生活型態的六個構面是否具備因素以及結構的恆等(factorial and structural invariance)，如果因素具備測量恆等性，則進行男女新生在此六個構面的因素平均數差異性比較。以國內某一大學的新生（包括大學部、研究所）為研究對象，男女樣本各為384人。研究結果顯示，模式良好適配更增強「健康促進生活型態中文簡式量表」的效度，因此「健康促進生活型態中文簡式量表」是一份可實行的(viable)以及可推廣的測量工具。在恆等性上，男女生模式具備形貌恆等，尺度、因素變異以及共變數恆等，但在營養及人際支持兩個因素，只具有部分截距恆等及兩道題信度不恆等。此外，平均數的檢定結果亦顯示，男生的運動生活型態優於女生，而女生的人際支持生活型態則優於男生。

The purpose of this study was to investigate the measurement invariance on Health-Promoting Life Profile (HPLP)， to confirm the existence of cross-group reliability and validity， furthermore to examine if there were any factorial and structural invariance among 6 dimensions of HPLP. If the factors revealed measurement invariance， then compared the mean difference between males and females. The research subjects were students of one university's freshmen (including under and graduate students) in Taiwan， 384 samples for each of two genders. The results showed that high goodness of fit would promote the validity of Health Promotion Lifestyle Profile: Short Form (HPLP-S)， therefore HPLP-S seemed to be a viable instrument of measurement in this study or future studies. Regarding the invariance， both genders presented configural invariance， metric invariance， factorial variance， and covariance invariance. The factors of nutrition and interpersonal support are only partial intercept invariance. Besides， there were two items showed reliability non-invariance. The factorial mean test displayed that the exercise life style was better in males than in females when females performed better in interpersonal support life style than males.
