The elicitation study of physical activity for Saudi youngsters (N= 104; boys= 56, girls= 48; age M= 15.1 years, SD= 1.2) aimed to identify the modal salient behavioral, normative, and control beliefs. Results revealed that youngsters recalled a limited number of beliefs, and also showed that the contents of modal salient behavioral (active or energetic, fatigue or tired, strength, weight control, fitness, blood circulation, and injury), normative (friends, father, relatives, mother, sisters and athletes) and control beliefs (lack of places and facilities, of time, of equipment, of social support, and bad weather) were endorsed by at least 30% of the sample and for each gender.
