CULTURAL ADAPTATION AND PSYCHOMETRIC EVALUATION OF THE NORMATIVE BELIEFS ABOUT AGGRESSION SCALE IN BANGLA

Abstract

With the increased aggressive behavior observed among the children and
adolescents in Bangladesh, it is pressing to investigate plausible aggression
scripts acquired in childhood that may cause aggressive behavior at a later age.
Normative Beliefs about Aggression Scale (NOBAGS) is such a popular tool to
identify aggression scripts by measuring children’s cognitive dispositions toward
aggressive behavior. The current study culturally adapted and psychometrically
validated the NOBAGS for elementary school students. After translating all 20
items, it was administered to 210 children (pilot: 30, field study: 180), ages
ranging from 10 to 11 years, recruited from two different schools in Dhaka using
the convenience sampling method. The Bangla NOBAGS retained all 20 items of
the original scale with a latent structure of six correlated components. The Bangla
NOBAGS showed satisfactory reliability estimates (Total scale: McDonald’s ωt
=.96; subscales McDonald’s ωt: .68-.90) and validity evidence. The psychometric
sound properties of the Bangla NOBAGS suggest the plausible use of this scale to
assess elementary school children’s perception towards aggressive behavior.
