The bottom quartile inside the Enjoyable/Social index was described as lower Enjoyment/Social. The best quartiles within the Demand/Status and Escape indexes ended up outlined as superior Need/Status and significant Escape, respectively.We utilized the Melancholy Self-Rating Scale (DSRS) with the Diagnostic and Statistical Guide of Psychological Conditions, 4th Version (DSM-IV) to evaluate depressive symptoms.
