Can the Perceived Barriers to Psychological Treatment Scale be used to investigate treatment barriers among females with disordered and non-disordered eating behaviours?
چکیده انگلیسی

•Psychometric investigation of the PBPT was conducted in a disordered eating sample.•A 25-item, seven-factor solution was supported.•Internal consistency and construct validity of the scale was also supported.•The PBPT is appropriate to measure barriers in disordered eating populations.

There is a lack of psychometrically sound instruments to assess treatment barriers among individuals with disordered eating behaviours. This study examined the factor structure and psychometric properties of the Perceived Barriers to Psychological Treatment scale (PBPT; Mohr et al., 2010) among a sample of individuals with disordered eating behaviours. Participants were 708 females aged 14 years and older who completed an online survey. The sample was randomly divided in two for the conduct of exploratory (EFA) and confirmatory (CFA) factor analyses. EFA suggested a seven-factor structure retaining 24 of the original 27 items (variance explained = 60%, α = 0.91). Factors were stigma, participation restrictions, negative evaluation of treatment, lack of motivation, emotional concerns, access restrictions, and time constraints. To assess clinical sensitivity, we conducted a secondary EFA utilising only clinical cases from this sample, which supported the solution but suggested retaining 25 of the original 27 items (variance explained = 58%, α = 0.89). The 25-item, seven-factor solution was further supported by CFA with an independent sample. Construct validity was also supported. The study suggests that the instrument will provide clinicians and researchers with a valid and reliable method of assessing treatment barriers in disordered eating samples.
