Abstract

The Involvement Evaluation Questionnaire (IEQ) was developed to evaluate burden among caregivers of patients with schizophrenia. We aimed to examine its psychometric properties among caregivers of patients with eating disorders (ED). A prospective study was carried out, recruiting caregivers of patients with an ED attending two outpatient clinics in Bizkaia, Spain. Caregivers provided sociodemographic information and completed the Involvement Evaluation Questionnaire (IEQ), the Hospital Anxiety and Depression Scale (HADS), the Short-Form 12 (SF-12) and the Anorectic Behaviour Observation Scale (ABOS). The same information was requested one year later. The confirmatory factor analysis (CFA) provided satisfactory fit indexes. Almost all of the factor loadings were above 0.40. Cronbach's alpha coefficients were mostly superior to 0.70. The correlation coefficients between the IEQ domains and the other questionnaires were lower than the Cronbach's alpha coefficients. Known-groups validity was supported by significant differences in the IEQ mean scores according to certain variables, as contact hours, living with the patient, type of caregiver and gender. The indexes employed for the evaluation of responsiveness were between 0.13 and 0.99. The IEQ has good psychometric properties and can be used to evaluate burden among caregivers of patients with ED.
