Abstract
The study of school motivation behavior of adolescent is crucial for every culture; but there is no valid scientific tool for measuring the same in Bangladeshi culture. Considering the significance of the School Motivation Inventory (SMI), the purpose of the present study was to culturally adapt the SMI (Indian Bangla version) into Bangla and validate in Bangladeshi culture. One thousand participants (491 males & 509 females) participated in the study. Exploratory Factor Analysis (EFA) which was done on sample 1 (n1 = 500) identified a three-factor of the SMI with 30 items. The three factors namely ‘Commitment, interest & enthusiasm’ ‘Affiliation with parents and peers’ and ‘Making excuse and blaming others’ together explained 42.35% of the total variance. When analyzed the data for sample 2 (n2 = 500) in Confirmatory Factor Analysis (CFA), it was revealed that the three-factor model with 30 items is an acceptable model fit [χ 2 (398) = 2.18, RMSEA = .05; RMR = .07; CFI = .90, GFI = .89] to the data. Moreover, the SMI showed good internal consistency (Cronbach’s α = .91) and strong convergent and discriminant validity. Thus, the Bangla version of SMI appears to be valid and reliable and therefore may be used in further research for measuring school motivation behavior of adolescent student in the perspective of Bangladesh.
