The purpose of this study was to investigate the psychometric Indices of the 14-item Questionnaire of Mental Scale (TSV; Wu & Fan, 2016) in the Iranian student community. Participants were 260 students from Damghan State universities who were selected by cluster sampling. Participants responded to individually Task Subjective Value scales, Achievement behaviors, and academic self-efficacy in a single classroom session with the same set of tools, respectively. Exploratory and confirmatory factor analysis were used to evaluate the construct validity of the TSV Scale. The results of principal component analysis with varimax rotation showed that the TSV scale consists of two subscales Utility-Attainment value and intrinsic values. Confirmatory factor analysis results by comparing competing single-factor, two-factor and four-factor models showed that the two-factor structure of the scale had a better fit to the data and all fit indices confirmed the fit of the model. Also, the internal consistency of the TSV subscales using the Cronbach's alpha method was appropriate. To estimate the criterion and convergent validity of the correlation coefficients of the TSV subscales with the subscales of effort and persistence on the Scales of achievement Behaviors (Wu & Fan, 2016) and academic self-efficacy (Pint rich and De Groot, 1990). The level of 0.01 was significant. Totality, the results of the present study provide evidence for the validity and reliability of TSV as a tool for assessing the subjective value of homework among Iranian students and can be used by researchers.
