Psychological, social, and environmental factors in the home were assessed.

The MHES displayed content validity for evaluation of the comprehensive home environment.

The MHES is internally consistent (adolescents: α = 0.82, mothers: α = 0.83).

Test–retest reliability of the scale was high (adolescent: r = 0.90, mother: r = 0.91).

This scale is a valid tool to evaluate home environment factors that impact obesity in adolescence.
