HLM provides unstandardized coefficients. Effect sizes, r_w^(f1v), were calculated following recommendations by Rights and Sterba (2019). The r_w^(f1v) statistic is defined as the square root of the proportion of variance explained by within-person predictors via fixed slopes and random slope variation/covariation. This is similar to a measure of the square root of the proportion reduction in variance, akin to a correlation (Hox, 2002; Kreft & de Leeuw, 1998; Raudenbush & Bryk, 2002). Due to space constraints, 95% confidence intervals are presented in Supplemental Table 2.
