The Spanish validation of an Eating Disorders Symptom Impact Scale (EDSIS) among caregivers.
(2008b) Development and validation of an eating disorders symptom impact scale (EDSIS) for carers of people with an eating disorder.
Discriminant validity was examined using cross-sectional data to examine the strength of association between subscale scores of the new scale LEE-S (Level of Expressed Emotion-Spanish version) and psychological distress (GHQ-12) as well as specific aspects of caregiving related to the symptoms (EDSIS), using Spearman correlations (non-normal distribution).
Discriminant validity was determined through correlations between the four subscales scores and the total LEE-S score, and the total score of the EDSIS and its subscales and the GHQ-12 total score.
With respect to discriminant validity, we found moderate correlations between scores on the LEE-S scale and the specific ED caregiving experience (EDSIS) as well as psychological distress (GHQ-12), which suggests that EE evaluated with a self-report instrument and from a relative's perspective is a relevant construct that may have prognostic significance in family-based interventions, as also shown with the FMSS (Sepulveda et al., 2010; Uehara et al., 2001) and the CFI (van Furth et al., 1996).
