Notes:

Values in bold indicate a likelihood ratio chi-square p-value of <0.20.

* The categories for this variable were aggregated into a binomial compliance measure for the univariate logistic regression. Children who exhibited ‘situational’ or ‘committed compliance’ to their mother’s clean-up request were considered compliant (Compliance= ‘Yes’). Children who exhibited ‘passive noncompliance’, ‘overt resistance’ or ‘defensive responding’ were considered noncompliant (Compliance = ‘No’).

** The responses for this variable were aggregated into a binomial temporary storage measure for the univariate logistic regression. The following responses were recoded to a ‘Yes’ response in the new binomial variable: ‘Some of the time’ or ‘Most times’. A ‘None of the time’ response was recoded to a ‘No’.
