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.

Acceptance and commitment therapy is trying to facilitate a valued living; although, there is not a valid scale for assessment of this concept. The items of questionnaire that are taken from ACT texts and well validated in English; items were translated and afterward three ACT experts checked out formal validation of translated Valuing Questionnaire (VQ). Exploratory and confirmatory factor analysis made for tow factor (1st factor= progress (in valued living), 2nd factor= obstruction (for valued living)) in student publication (N=502) with one subsample (N=300) for exploratory factor analysis and another (N=202) for confirmatory factor analysis. Results of exploratory factor analysis showed tow factor with 54.17 percent of whole variance. Indices of CIMIN/df، NFI، CFI، RMSEA used for fit indices, after effect of modification indices respectively 1.93, 0.06, 0.95, 0.90, 0.87 were received; as regards proposed model was fit with model of exploratory factor analysis. Also in study of reliability by method of Cronbach's alpha for Progress scale α= 0.79 and for Obstruction scale α=0.77 were received that show a good reliability for scales. Valuing Questionnaire (VQ) as a scale for substitution with symptom oriented scales, allow researcher and therapists a rapid, reliable and valid assessment.
