There is a growing body of theoretical and clinical literature highlighting the role of pride in maintaining eating disordered behaviours. Despite its clinical importance, there are no measures to assess feelings of pride associated with eating psychopathology. This study describes the development and validation of the Pride in Eating Pathology Scale (PEP-S), a self-report questionnaire that examines feelings of pride towards eating disordered symptoms (e.g., pride in food restriction, thinness and weight loss). Participants were 390 females, recruited from university and community populations, whose mean age was 26.99 years. Respondents rated pride in eating pathology on a 7-point Likert-scale. Principal Component Analysis indicated that the 60-item scale comprised a four component structure: (1) pride in weight loss, food control and thinness, (2) pride in healthy weight and healthy eating, (3) pride in outperforming others and social recognition and (4) pride in capturing other people's attention due to extreme thinness. These four components explained a total of 65.31% of the variance. The PEP-S demonstrated very good internal reliability (α ranging from 0.88 to 0.98) and very good test–retest reliability over a 3-week time-span (r ranging from 0.81 to 0.93). The PEP-S also showed excellent convergent and discriminant validity. Furthermore, the scale discriminated between women with high and low levels of eating psychopathology. The PEP-S is a psychometrically robust measure of pride in eating pathology. It has the potential to advance theoretical understanding and may also be clinically useful. Copyright
