Early Maladaptive Schemas (EMS) are described as long-held core beliefs which are dysfunctional to a significant degree. However, the supposition that schemas are dysfunctional by nature, while not isomorphic with psychiatric syndromes, is yet to be subjected to empirical review. The current study seeks to investigate the relationship between the Young Schema Questionnaire and the concept of 'dysfunction' in a community sample to determine the indirect effects of psychiatric symptomatology and validate current scoring guidelines with a convergent measure of dysfunction. A total of 464 people completed a survey online comprising of the YSQ-Short Form, the Depression, Anxiety and Stress Scales-21, the Social and Occupational Functioning Assessment Scales, and the World Health Organization Quality of Life Scale. Multiple regression analyses revealed a moderate relationship between EMS categories and measures of dysfunction, however only six of eighteen EMS categories were significant predictors in this model. Mediation analyses further suggest that the relationship between EMS and dysfunction is partially mediated by psychiatric symptomatology. The current dichotomous clinical scoring guidelines were found to be invalid when measures of functioning were used as convergent measures for twelve of the EMS categories. These findings suggest the YSQ is best conceptualised as a general measure of schema as opposed to a measure of EMS categories.
