OBJECTIVES: Greece ranks first among OECD member countries in childhood obesity. Meanwhile, the WHO, noted a significant increase in childhood obesity in Greece, based on two studies: one conducted prior to and one during the economic crisis. The purpose of this study was to develop and test 3 self-administered questionnaires identifying the factors that facilitate childhood obesity in Greece, during the economic recession. METHODS: Data were collected from 450 parents of children aged 6-12 (n), 450 parents of children aged 12-15 (n), and 250 adolescents aged 12-15 (n), from the region of Attica. Exploratory factor analysis (EFA) was performed and Confirmatory Factor Αnalysis (CFA) followed in another sample (n=163, n=163, n=93) from 3 different regions to verify the factor structure. Cronbach’s alpha (α) and Intraclass Correlation Coefficients (ICC) were used to test reliability. RESULTS: EFA results support the factorability of the correlation matrix. (Kaiser-Meyer-Oklin: 0.941-0.944 and Bartlett’s test of Sphericity <0.001 in all cases). CFA revealed that the final models (6-factor models for parents and 5-factor models for adolescents) provided the best fit for our samples (RMSEA: 0.04-0.05 and CFI:O.90-0.94). The following subscales were included in parents’ questionnaires: 1. Physical activity and sedentary lifestyle, 2. Eating habits and style, 3. Motives for choosing foods (including economic concerns) 4. Parents’ involvement and monitoring, 5. Nutrition environment, 6. Parents’ perceptions of nutrition and weight. Also, perceptions of body image and nutrition and subscales 1, 2,3, and 5 were included in adolescent questionnaires. Cronbach’s alpha and ICC showed acceptable reliability (α: 0.79=0.90 and ICC:>0.67-0.91). CONCLUSIONS: All three questionnaires satisfy the principles of reliability and validity, and are useful in planning action programs for childhood obesity. Nevertheless, there is an apparent need to replicate factor studies and reliability tests on larger samples in order to increase the generalizability of results.
