Academic procrastination is one of the main problems students encounter during studying. It affects their mental health, academic performance, and even everyday activities. A lack of time management was once thought to be the cause of procrastination. Procrastination, however, has been linked to mood control, according to recent studies. Decision-making is also a factor that is influenced by emotion or a person's affect. The present study aims to find whether decision-making and affective styles influence academic procrastination among Indian students. The participants (N = 211) who are currently studying any discipline in a regular mode and who are between the ages of 17 to 30 years (mean = 21.10 & SD = 2.168) were selected using purposive sampling, and data was collected online using Academic Procrastination Scale, General Decision-Making Style Instrument and Affective Style Questionnaire. Data were analyzed using Pearson correlation, along with multiple regression analysis. Results found a significant inverse correlation between rational decision-making and academic procrastination and a weak inverse correlation between adjusting affective style and academic procrastination. A significant positive correlation between avoidant decision-making and academic procrastination was also found. Through regression analysis avoidance, decision-making has been found as a positive predictor of academic procrastination along with rational decision-making, and spontaneous decision-making as negative predictors. No significant correlations were found for academic procrastination with intuitive, dependent, spontaneous, concealing, and tolerating styles. The current results contribute to the existing literature on academic procrastination and the development of effective strategies to reduce academic procrastination by managing unhealthy decision-making styles.
