The Bangor Mindful Parenting Scale (BMPS) is intended for parents of children with intellectual disabilities (ID) and/or autism spectrum disorder (ASD). The 15-item BMPS was developed based upon the Five Facet Mindfulness Questionnaire (see Appendix for the original scale). An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted on the BMPS using a sample of over 500 parents of children with an ID and/ ASD. The BMPS demonstrates good internal reliability and construct validity, with a four-factor structure. However, this four-factor model had multiple cross-loading items. It is recommended that future researchers using the 15-item BMPS use EFA on their own data to extract factors for further analysis. There remain limitations in the literature surrounding the concept of mindful parenting for parents of children with ID, which parallel the difficulties that researchers working to develop and refine trait mindfulness scales have worked with for over a decade.
