This study examined whether preschool children differed on measures of psychosocial functioning both cross-sectionally and longitudinally. One hundred and thirty-two children who varied in levels of body fat participated in the study along with their natural parents. Results indicated that the children did not differ in levels of self-esteem and family functioning as a function of their body fat. Prospectively, physical self-esteem weakly (but significantly) correlated with body fat at 1 and 2 years, and father's perception of family functioning predicted body fat at 1 year only. Results suggested that childhood obesity may not develop as a result of psychosocial factors.

The development of a healthy eating style and physical fitness regimen in adolescence or adulthood might be contingent on physical self-concept in childhood. Most available measures of physical self-concept are inappropriate for use with 1st and 2nd grade children, so the present study developed, piloted, and partially validated the 27-item Children's Physical Self-Concept Scale (CPSS), which assesses Global physical self-concept and subscales of Physical Performance, Physical Appearance, and Weight Control behaviors in children 6 to 11 years of age. The test exhibits adequate test-retest reliability and internal consistency. A comparison of 316 normal and overweight children indicated that normal-weight children obtained higher Global physical self-concept scores and higher subscale scores. In addition, the CPSS distinguished test groups of diabetic, overweight, and normal-weight children in a contrasted-groups analysis.
