Development of self-report scales measuring collaborative vs. directive support: Assessing beliefs and behaviors in carers of adults with eating disorders.

Collaboration is more acceptable and likely to produce favorable outcomes when providing care to individuals with eating disorders compared to directive care. We developed two self-report instruments that assess the extent to which carers (e.g., family, friends) of individuals with eating disorders provide collaborative vs. directive support (Support Behaviors Scale; SBH) and the extent to which carers believe that such approaches are helpful (Support Beliefs Scale; SBL). Participants were mothers, fathers, partners, friends and siblings (N=141) of eating disorder patients in hospital or residential treatment. Confirmatory factor analyses were used to test measurement models comprising collaborative and directive approaches identified in previous research. A 19-item three-factor model exhibited best fit for each scale and included three distinct caregiving approaches: two that were collaborative (encouraging, concerned), and one that was directive. The scales exhibited acceptable internal consistency. Reported caregiving behaviors (SBH) were correlated with beliefs about caregiving (SBL). The scales can be used to assess caregiving stance and outcomes for interventions aimed at promoting collaboration in carers.
