The goal of this observational study is to learn about the relationship between self-efficacy and academic burnout among sports science undergraduates in Indonesia. The main questions it aims to answer are:

• Is higher self-efficacy associated with lower academic burnout among sports science undergraduates?
• Does higher self-efficacy reduce the odds of experiencing moderate academic burnout?

A total of 233 sports science undergraduates (semesters 3-4) at State University of Makassar, South Sulawesi, Indonesia took part in this study. Most participants were male (71.2%), aged 20-21 years.

Participants completed two questionnaires on a single occasion:

• The General Self-Efficacy Scale-12 (GSES-12) to measure self-efficacy
• The Maslach Burnout Inventory-Student Survey (MBI-SS) to measure academic burnout

NOTE: This study was retrospectively registered. The study was conducted from March to May 2025 and received ethical clearance (No. 95/UN4.6.4.5.31/ PP36/2025) from the Biomedical Research Ethics Committee, Faculty of Medicine, Hasanuddin University, on February 11, 2025, prior to study initiation. Registration was performed after study completion due to the investigator's initial unawareness of prospective registration requirements. No outcome measures, study design, or statistical analysis plan were modified following data collection.

This cross-sectional observational study examined the association between self-efficacy and academic burnout among sports science undergraduates in Indonesia.BACKGROUND:Academic burnout is a significant mental health concern among university students, particularly those facing dual academic and athletic demands. Self-efficacy - the belief in one's ability to succeed despite challenges - has been proposed as a protective factor against burnout. However, evidence among Indonesian sports science students remains limited.STUDY POPULATION:Participants were junior-year sports science undergraduates (semesters 3-4) at State University Of Makassar, South Sulawesi, Indonesia, recruited via simple random sampling during March to May 2025.MEASUREMENTS:Self-efficacy was measured using the General Self-Efficacy Scale-12 (GSES-12). Academic burnout was measured using the Maslach Burnout Inventory-Student Survey (MBI-SS). Both instruments were administered on a single occasion in supervised classroom sessions.STATISTICAL ANALYSIS:Data were analyzed using Spearman rank-order correlation and binary logistic regression. Normality was assessed using the Kolmogorov-Smirnov test. Statistical analyses were performed using IBM SPSS Statistics version 24.0. A p-value less than 0.05 was considered statistically significant.ETHICAL APPROVAL:This study was approved by the Biomedical Research Ethics Committee, Faculty of Medicine, Universitas Hasanuddin (No. 95/UN4.6.4.5.31/PP36/2025) on February 11, 2025. All participants provided written informed consent prior to enrollment. The study was conducted in accordance with the Declaration of Helsinki.NOTE: This study was retrospectively registered. Data collection was conducted from March to May 2025, following ethical clearance obtained on February 11, 2025. Registration was performed after study completion due to the investigator's initial unawareness of prospective registration requirements. No outcome measures, study design, or statistical analysis plan were modified following data collection.
