Note. N = 607 person days. Overall χ² tested whether the proportions of each type of mode day differed by the categorical correlates.

‘-‘ indicates insufficient variability for testing.

^an = 357 only assessed on social use days; assessed using ‘check all that apply’ so endorsements are not mutually exclusive to each other.
