Psychological variables that affect mental health are divided into useful and harmful variables. Useful variables are beneficial for improving mental health and quality of life, and increasing well-being, for instance, happiness, calmness, vigor, and mental toughness. Harmful variables reduce mental health, quality, and enjoyment of life, for example, negative mood states, anxiety, and burnout. This study aimed to predict psychological burnout based on mood states and mental toughness of elite athletes with physical disabilities. Participants have included 150 athletes with physical disabilities (77women; 73men) competing at national or international Paralympic sports teams (mean age=42.34 ±7.44y, mean experience=8.38 ± 3.19 y) that were selected in the random method. Participants accomplished the Athlete Burnout Questionnaire, the 32-item Brunel Mood Scale, and the Sports Mental Toughness Questionnaire. Stepwise multiple linear regression analysis showed that happiness (moderate negative power, 51%), vigor (weak negative power, 28%), fatigue (weak positive power, 22%), mental toughness (medium negative power, 57%), and confidence (weak negative power, 29%) were able to predict the total burnout of the athletes with disabilities. These findings are essential for psychologists since developing and increasing the useful variables and inhibiting or decreasing the harmful variables for mental health can prevent sports burnout.
