THE COURSE OF PROBLEMATIC SMU 213 7 adolescents, respectively ( B = 1.174, p < 0.001, OR = 3.241 and B = 1.445, p = 0.001, OR = 4.250). Lower life satisfaction ( B = -1.349, p < 0.001, OR = 0.263), higher attention deficit ( B = 1.050, p = 0.008, OR = 2.914), and higher impulsivity ( B = 1.607, p < 0.001, OR = 5.051), were associated with a greater probability of being in Class 1 compared to Class 4. Figure 7.4 Estimates From Multivariate Multinomial Regression Analysis on Class Membership, n = 1,419 Notes. Estimates are logit coefficients. Ref. = reference category. Class 1 = variably high problematic SMU, variably high SMU frequency; Class 2 = persistently high problematic SMU, persistently average SMU frequency; Class 3 = persistently low problematic SMU, persistently low SMU frequency; Class 4 = persistently low problematic SMU, variably high SMU frequency. Class 2: Persistently High Problematic SMU, Persistently Average SMU Frequency Class 2 and 4 did not vary by demographic characteristics. The lower the level of life satisfaction and social competencies, the higher the probability of being in Class 2 compared to Class 4 ( B = -0.793, p = 0.013, OR = 0.454; B = -2.634, p < 0.001, OR = 0.073).
