DV= Dependent Variable.
All coefficients are unstandardized beta weights. Values reported are unstandardized mixed model regression coefficients. f2 is computed as a measure of effect size, and provides an estimate of variance accounted for by sleep quality. Pain Interference is adjusted for Employment and Disability Compensation. All others are adjusted for Disability Compensation.
