a Measured on a 9-point scale (range 1–9). b n = 106 for age and sex and n = 103 for BMI. c n = 115 for age and n = 114 for BMI. d n = 104 for age, sex, and BMI. Reasons for missing values were response inconsistencies between session 1 and 2 for age and sex and implausible responses for BMI (i.e., an unrealistic low or high reported weight or length).
