Evaluation of Psychometric Properties of the Spontaneous Self-Affirmation Measure in male students in the third grade of secondary schools in Ilam

Personal characteristics and abilities and reflecting on them, which is referred to as self-affirmation, can be the basis for increasing self-esteem, psychological and physiological well-being, academic progress and academic motivation of students. Therefore, the lack of a suitable tool to measure it in students, caused Harris et al. (2019) automatic self-verification measurement of translation and its psychometric characteristics to be investigated in this research. The current research is a descriptive research of the correlation type. The statistical population was all male students in the third grade of secondary schools in Ilam in the 2021-2022, of which 330 were selected by one-stage cluster random method. The obtained correlation was positive for convergent validity with the intrinsic motivation subscale of Harter (1980) (p<0.05) and negative for divergent validity with the depression, anxiety and stress questionnaire (DASS-21) of Lovibond and Lovibond (1995) (p<0.05). The obtained correlation was positive for convergent validity (p<0.05) and negative for divergent validity (p<0.05). In addition, the result of the study shows a desirable suitability of parameters. (RMSEA = 0.08, CFI = 0.944, GFI = 0.906, CMIN/DF= 3.21). The results of the factor analysis showed that the three factor model including abilities, values and social relations of this measure had the best fit with a suitable factor load (at least 0.70). The reliability of this measure was calculated using Cronbach's alpha method, whose coefficients were reported as 0.93 for the whole Measure, 0.85 for the first factor, 0.82 for the second factor and 0.87 for the third factor.
