Cross-cultural adaptation and validation of the Greek version of the Family Questionnaire for assessing expressed emotion

Expressed emotion (EE) has proved to be an established factor in short-term relapse in schizophrenia the aim of the present study was to examine the psychometric properties of the Greek version of the Family Questionnaire (FQ), a brief self-report questionnaire measuring the EE status of relatives of patients with schizophrenia in terms of criticism (CC) and emotional overinvolvement (EOI) the translated and adapted 20-item FQ was administered to 176 family caregivers of patients with schizophrenia and bipolar disorder. Caregivers' burden (Family Burden Scale) and psychological distress (General Health Questionnaire-28) were also evaluated the findings indicated that the Greek version displays a two-factor structure with two subscales of EE - CC and EOI - with 10 items each, similarly to the original version the convergent validity of the subscales was highly supported by correlations with caregivers' burden and psychological distress the Cronbach's α coefficient measuring internal consistency for the two scales were 0.90 for CC and 0.82 for EOI the test-retest correlation coefficients measuring reproducibility were 0.99 and 0.98 for CC and EOI, respectively the Greek version of the FQ appears to be a valid and reliable instrument to be used in both research and clinical assessment of family EE.
