the SCL-20 total scores are the average values for the 20 items, ranging from 0 (not depressed at all) to 4 (extremely depressed)
the mean score on each identified factor was estimated by taking the mean of the raw values of items with salient loadings on the factor multiplied by the standardized scoring coefficients
indicates a significant difference between the mean score on the dysphoric mood factor and anhedonia factor (p <0.0001, Cohen’s d=1.82)
indicates a significant difference between the mean score on the dysphoric mood factor and sleep disturbance factor (p <0.0001, Cohen’s d=1.42)
indicates a significant difference between the mean score on the anhedonia and sleep disturbance factor (p <0.0001, Cohen’s d=0.42)
indicates a significant difference across men and women (p <0.05, Cohen’s d=0.22 for total score and 0.32 for sleep disturbance factor)
