Dependência do estado afetivo e estabilidade relativa do traço do perfeccionismo nas perturbações de sono

Objective: To evaluate the degree of absolute change, relative stabilityand state dependence of trait perfectionism in sleep disturbances ina sample of university students. Method: Participants completed theMultidimensional Perfectionism Scale and two items concerning sleepdifficulties. The mean age at T0 (baseline) was 19.59 years (SD = 1.61,range = 17-25) and 62.5% of the sample were female. Results: Absolutechanges in self-oriented and socially-prescribed perfectionism were found.Relative stability was found for all perfectionism dimensions. Prior andconcurrent sleep disturbances explained a significant amount of variancein perfectionism. Controlling for the effects of sleep measures, prior selforientedperfectionism and other-oriented perfectionism were the onlysignificant predictors of subsequent self-oriented perfectionism and otherorientedperfectionism, at T1 and T2. Difficulties falling asleep at T1and socially-prescribed perfectionism at T0 were significant predictors ofsocially-prescribed perfectionism at T1. Conclusion: Despite significantchanges in perfectionism mean scores over the follow-up, the correlationanalyses demonstrated that participants remained quite stable in regard totheir relative levels of perfectionism. As concurrent difficulties initiatingsleep also predicted concurrent socially-prescribed perfectionism, thisseems to be one dimension of perfectionism with trait-state characteristics.
