The properties of the student Engagement Multidimensional Scale in School

The aim of this study was to investigate the psychometric properties of the student engagement scale in school. Population of this study were all of the students of Mahdishar city in Semnan province in 2015-2016. Participants were 502 students of 7th to 9th grades (252 male and 250 female) that were selected via stratified random sampling method. All of them completed student engagement instrument (SEI) and student engagement multidimensional scale (SES-4DS). Exploratory factor analysis, item-total correlation and reliability analysis to evaluate psychometric characteristics of this questionnaire were conducted. Confirmatory factor analysis to study the measurement model and internal structure of items was carried out. Convergent validity with student engagement instrument and criterion validity with math and discipline score was studied. Results showed that the student engagement multidimensional scale in the school is saturated with four factors. The student engagement multidimensional scale in School showed positive and significant correlation with the Student Engagement Instrument (0/67), mathematics (0/14) and discipline (0/099). Reliability of the student engagement multidimensional scale in school via Cronbach's alpha, 0/82 and reliability of cognitive, emotional, behavioral and agency subscales computed 0/65, 0/75, 0/77 and /076, respectively. The findings suggest that Persian version of the student engagement multidimensional scale in School has acceptable psychometric properties and can be used as a valid instrument in academic and educational studies.
