A considerable amount of research on the relations between perfectionism and sleep exists, where perfectionism negatively affects sleep quality. Mediators, primarily anxiety, affecting sleep quality have been investigated as well. However, within the bounds of conducted literature search, research with a mediatory model of maladaptive repetitive thinking (MRT) on perfectionism and sleep quality in a student population seems to require further exploration. Therefore, current work investigated whether MRT (i.e., worry and rumination) mediates the relationship between perfectionism and sleep quality. Data was analyzed from an overarching main study which, through convenience sampling, recruited 69 healthy university students who filled in online questionnaires (e.g., assessing rumination and sleep quality). In line with previous research, results showed that increased perfectionism was related to worse sleep quality and increased maladaptive repetitive thinking. Furthermore, increases in maladaptive repetitive thinking was related to worse sleep quality. However, the proposed mediation was found to be nonsignificant. Several limitations were at play (e.g., self-report measurements), thus it is recommended to replicate the current work and minimize these limitations. As sleep has a wide array of implications on healthy overall functioning it is recommended to explore the triad further, paving the way to innovations to improve sleep quality and consequently healthy functioning in the student population.Show less
