Perseverative Thinking, Sleep Quality, and Academic Performance in Adolescents

Abstract

The research study examines perseverative thinking, sleep quality and academic performance among adolescents. The study was delimited to a group of intermediate-level students, aged 15-19. Cognitive and behavioural factors play a key role in educational outcomes during the teenage stage. According to research, repetitive negative thinking and poor sleep patterns affect emotional regulation, concentration and academic success. The data were collected from 150 college students using a standardized instrument, following a quantitative, correlational research design and random sampling. The Perseverative Thinking Questionnaire (PTQ), Sleep Quality Scale (SQS), and Academic Performance Scale (APS) are applied. For Statistical analysis, the Statistical Package for the Social Sciences (SPSS), including regression, correlations, independent-samples t-tests, and mediation analyses. As a result, perseverative thinking negatively predicts academic performance, while sleep quality positively predicts it. While sleep quality partially mediates, significant gender-based differences are also revealed. Thus, educational institutions should support cognitive-behavioural interventions and sleep hygiene to reduce negative thinking patterns and enhance adolescent academic achievement
