Identifying the determinants of positive coping is a critical step in empowering the parents of children with intellectual disability. In this context, this study aims to develop a scale to assess the determinants of positive coping. Accordingly, culturally relevant items were pooled, got validated by experts and refined. The scale was administered to 150 parents of children with intellectual disability. Factor analysis done through polychoric correlation helped reduce the items. Cronbach's alpha coefficients were established for reliability testing. The validity of the new scale was examined with the subjective wellbeing on a visual analogue scale and Family Interview for Stress and Coping in Mental Retardation. The new scale has a Cronbach's alpha of 0.71 and an intraclass correlation of 0.64. After factor analysis, 12 items were retained in the final version. This study also identified specific factors associated with positive coping. The new scale can be used with parents of children with intellectual disabilities to identify the determinants of positive coping.
