Note. Gender: male coded 1, female coded 0; race: white coded 1, non-white coded 0; ethnicity: Hispanic/Latino(a) coded 1, non-Hispanic/Latino(a) coded 0; activity participation: at least one activity coded 1, no activities coded 0; part-time job coded 1, no job coded 0; O.R. = odds ratio; C.I. = 95% confidence interval. Statistically significant results at p ≤ .01 indicated in bold. Two-way interactions of part-time job status with impulsivity and with sensation seeking were tested initially in each model, however these interactions were dropped when not statistically significant. Thus the results presented here include only statistically significant interaction terms.
