^aMean summary scores are presented in the Results.

^bβ-Coefficient from univariate linear regression. Positive β-coefficients meant that the predictor (or increasing values of the predictor) was associated with better quality of life, whereas negative β-coefficients suggested that the predictor (or increasing values of the predictor) was associated with worse quality of life.
