The CDRS-R is a clinician-rated scale to measure the severity of depression of children and adolescents. The CDRS-R consists of 17 items: 14 items rate verbal observations, and three items rate nonverbal observations (tempo of language, hypoactivity, and nonverbal expression of depressed affect). Depression symptoms are rated on a 5-point scale from 1 to 5 for the verbal observations, and a 7-point scale from 1 to 7 for the nonverbal observations. The total score ranges from 17 (normal) to 113 (severe depression).

The Children's Global Assessment Score (CGAS) is a rating scale which measures psychological, social and school functioning for children. The CGAS is a clinician-rated global scale to measure the lowest level of functioning for a child (4 to 16 years) during a specified time period. The CGAS contains behaviourally oriented descriptors at each anchor point that depict behaviours and life situations applicable to a child. The items range in value from 1 (most functionally impaired child) to 100 (the healthiest). A total score above 70 indicates normal function.

The PedsQL™ VAS is designed to measure at-that-moment functioning in children and adolescents. The PedsQL VAS consists of 6 domains: anxiety, sadness, anger, worry, fatigue and pain using visual analogue scales. The functionality for each domain is measured on a 10 cm line with a happy face at one end and a sad face at the other (0-10 points). The patients are asked to mark on the line how they feel. A lower value represents a better outcome.

PQ-LES-Q total score (items 1 to 14). The PQ-LES-Q is a patient-rated scale designed to assess satisfaction with life. It is an adaptation of the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), which is used to measure quality of life in adults. The PQ LES Q consist of 15 items, item 1-14 assess the degree of satisfaction experienced by subjects in various areas of daily functioning (and item 15 allows subjects to summarize their experience in a global rating). Each item is rated on a 5-point scale from 1 (very poor) to 5 (very good). The total score range of item 1-14 (this outcome measurement) is 14 to 70, with higher scores indicating greater satisfaction.
