Background: Basketball is a highly complex and demanding game comprised various types of jumps, start acceleration, and sudden changes in movement direction, where the body of a basketball player is subjected to significant physical stress which, in the case of physical unpreparedness, may lead to sustaining injuries. The idea of re-injury can turn into a psychic problem by creating a fear of movement in the athlete and it affects the motivation, which is one of the performance parameters. Currently, there are no standardized or widely adopted measures to predict or assess the fear of re-injury in sports, making it a critical gap in athlete management and a pressing need for focused research and preventive strategies.

Objective: The study aims to find the prevalence of fear of re-injury and its impact on performance in amateur basketball players using a self-developed questionnaire.

Methods: A questionnaire-based, observational cross-sectional survey was conducted among amateur and recreational basketball players with a history of basketball-related injury during the preceding 12–15 months. A total of 104 valid responses from participants aged 14–30 years were analyzed. Data were collected using a self-developed 20-item Fear of Re-Injury Questionnaire (FRIQ), comprising psychological/cognitive and perceived physical-performance domains.

Results: The majority of participants demonstrated moderate fear and partial recovery, while a smaller proportion experienced severe fear and major impact. A statistically significant positive correlation was observed between the psychological and physical performance subscale scores (Pearson’s r = 0.59, p < 0.001). Based on the provisional interpretation bands, the majority of the participants, 74 (71.2%), were classified under the Moderate Fear/Partial Recovery category.

Conclusion: The Fear of re-injury questionnaire shows a positive correlation between fear of re-injury and performance in amateur basketball players. According to the reliability analysis of the questionnaire, the Cronbach's alpha is 0.934 which shows excellent reliability.
