Key to variables modeled: X1: RHP versus non-RHP. X2: Half-RHP versus non-RHP. M1: Identification with people in the photographs. M2: Attitude towards physical activity. Y: Intention to improve physical activity.
a
Standardized coefficient for binary predictors was standardized with respect to the outcomes only.
b
Covariates controlled in the models: Current physical activity level, smoking status, general health status, number of servings of fruits and vegetables per day, age, education, gender and income.
