This paper describes the initial psychometric evaluation of the Homework Purpose Scale (HPS), taking an illustration form practice in one country where it is used. The Homework Purpose Scale was designed to measure homework purpose. Both exploratory and confirmatory factor analyses were performed on samples of undergraduate students (N = 443). Results showed that the factor structure of the Turkish version of the HPS (where the study was carried out) was largely similar to the original one in the US. Moreover, each subscale demonstrated high internal consistency, and as predicted was correlated with theoretically related homework measures and other relevant constructs, along with displaying temporal stability. In brief, initial results indicate that the version of the HPS used here is a reliable and valid multidimensional measure for determining homework purpose. (C) 2013 Elsevier Ltd. All rights reserved.
