Bangla Version of the Transitional Impact Scale: Assessing Psychometric Properties Among Bangladeshi University Students

The Transitional Impact Scale (TIS-12) is a self-reported psychological assessment tool that measures the impact of life transitions by assessing material and psychological changes in a person after a transitional event. This study aimed to translate and validate the TIS-12 in Bangla among Bangladeshi university students. A total of 374 students from four universities completed a survey comprising demographic items, the Bangla TIS-12 (TIS-B), the Bangla Depression Anxiety Stress Scale (DASS-21), and the Bangla WHO-5 Well-Being Index. McDonald’s ω and Intra-class Correlation Coefficient (ICC) suggested good reliability of the TIS-B. Exploratory factor analysis revealed two factors (materialistic and psychological) replicating the factorial structure of the original scale. Confirmatory factor analysis supported a correlated two-factor model with good fit indices for the TIS-B. Measurement invariance testing using multi-group CFA demonstrated configural, metric, and scalar invariance across gender, and configural invariance across university type. Weak correlations with both the DASS-21 and WHO-5 indicated construct validity of TIS-B. In conclusion, the Bangla version of TIS-12 is a valid and reliable measure to assess the quality and quantity of changes brought about by transitional events within the Bangladeshi context.
