On the longitudinal interplay between perfectionism and general affect in adolescents

Abstract

Cross-sectional studies on perfectionism and general affect tend to interpret their findings suggesting affect is an outcome of perfectionism. However, personality theories posit that individual differences in general affect may also influence perfectionism. Expecting to find bidirectional relations, this 3-wave study sought to examine the longitudinal interplay between perfectionism and general affect in a sample of 489 adolescents (54% female) aged 12–19 years. Cross-lagged panel analyses showed a positive unidirectional effect from positive affect to perfectionistic standards as well as a positive bidirectional effect between perfectionistic concerns and negative affect. As expected, general affect was both an antecedent and an outcome of perfectionism. Implications of the findings for the development and outcomes of perfectionism are discussed.
