The Study of Psychometric Properties of the Brief Adolescents’ SubjectiveWell-Being in School Scale

The purpose of this study was to investigate the psychometric properties of the brief adolescents'''''''' subjective well-being in school scale at Iran students sampling. The research method was descriptive survey. The study population included all high school students in the second period Parsabad city (Ardabil province) in academic year of 2017, that selected across of theme using random cluster sampling, 303 students.

The internal consistency of the brief adolescents'''''''' subjective well-being in school scale was confirmed by Cronbach’s alpha coefficientswith coefficients ranging from 0.70 to 0.76. The test-retest reliability of the brief adolescents'''''''' subjective well-being in school scale was tested based on the results of two tests, with correlation coefficients ranging from 0.62 to 0.72 for the total score and its subscales was confirmed. Therefore, based on the findings of this study, it can be concluded that the brief adolescents'''''''' subjective well-being in school scale has enough validity and reliability to measure this structure in samples of Iranian students.
