Physical activity and self-perception in school children assessed with the Children and Youth -: Physical Self-Perception Profile

Aim: This study validated the Swedish translation of the Children and Youth - Physical Self-Perception Profile (CY - PSPP) scale and examined the relation between physical self-Perception and daily physical activity as well as the relationship between physical self-perception and body mass index (BMI) among Swedish school children. Methods: Forty-eight children aged 11-12 years completed the CY - PSPP twice with 2 weeks in between. Test-retest reliability, concurrent and content validity were calculated. Five hundred and one children, aged 10-14 years, were measured for height and weight and perceived physical self-perception. Activity levels were analyzed using pedometers for 4 consecutive days. Results: Good validity concerning concurrent and content validity was found. Test-retest reliability over a 2-week period was acceptable. In boys a fair and in girls a poor correlation between the sub-domains of the CY - PSPP and physical activity were found and a fair negative correlation between the sub-domains and BMI except for Physical Strength. Conclusion: The CY - PSPP distinguishes between children with low and high physical self-perception. The information is of importance when designing physical activity programs reachable for children with low physical self-esteem. According to the findings it is important to form physical activity programs that support and develop Sport Competence, Physical Condition and sense of Body Attractiveness among children.
