Popis: The anorexic voice (AV) is defined as a critical internal dialogue which has been implicated in the \ud development and maintenance of anorexia nervosa (AN). Systematic research to explore this further \ud requires a valid and reliable measurement tool. This study aimed to develop and assess the validity of \ud the Experience of an Anorexic VoicE Questionnaire (EAVE-Q). EAVE-Q items were developed and \ud checked for face and content validity through cognitive interviews with seven individuals diagnosed \ud with AN. Participants with a diagnosis of AN (N = 148) completed the EAVE-Q, sociodemographic \ud questions and measures of mood and quality of life to assess internal consistency and construct \ud 3 \ud \ud validity. Forty-nine participants completed the EAVE-Q twice more to assess test-retest reliability. \ud The EAVE-Q had good face and content validity and good acceptability. Principal axis factoring \ud resulted in an 18-item scale organised into five domains with high internal consistency (α = .70 to α \ud = .85). Domains correlated significantly with eating disorder symptoms, psychological distress and \ud quality of life. The EAVE-Q did not discriminate between participants on the basis of body mass index. \ud Test-retest reliability was moderate. Although the factor structure of the EAVE-Q requires replication \ud in other AN samples, the EAVE-Q is the first measure of a critical internal dialogue in AN. It is hoped \ud that it will aid future research to increase understanding of AN and the continued development of \ud person-centred treatments.
