Preliminary development of a questionnaire designed to measure neurotic perfectionism in the eating disorders

The preliminary development and validation of a new self-report questionnaire (the NPQ) for measuring neurotic perfectionism in the eating-disorder population is described. The 42-item instrument demonstrated satisfactory internal consistency. All test items correlated significantly with both SCANS P and SCANS D (subscales of the SCANS [Slade & Dewey, 1986]), thus indicating neurotic perfectionism according to Slade, Newton, Butler, and Murphy (1991), and discriminated well between controls and eating-disorder patients. NPQ scores demonstrated significant group differences on comparison of neurotic perfectionists with normal and non-perfectionists (defined by the SCANS) and with subjects who scored above the EAT-26 (Garner, Olmsted, Bohr, & Garfinkel, 1982) subscale cut-offs when compared with those who scored below.
