The systematic review revealed widespread utilization of developmentally appropriate QL instruments but less frequent use of both self and proxy reports and an inconsistent approach to age group specificities .
Research on the quality of life ( QL ) of children/adolescents with psychological disorders has flourished over the last few decades .
Given the developmental challenges of QL measurements in pediatric population s , the aim of this study was to ascertain the extent to which a developmental approach to  QL assessment has been applied to pedopsychiatric QL research .
Depression, anxiety and obsessive-compulsive symptoms and quality of life in children with attention-deficit hyperactivity disorder (ADHD) during three-month methylphenidate treatment
The current study was design ed to investigate the changes that occur in depression , anxiety , obsessive — compulsive symptoms and health-related quality of life during methylpheni date ( MPH ) treatment in children with attention-deficit hyperactivity disorder ( ADHD ) . Forty-five treatment naive children with ADHD , aged 8—14 , were assessed based on self , parent and teacher reports at the baseline and at the end of the first and third month of MPH treatment regarding changes in inattention , hyperactivity , impulsivity , depression , anxiety and obsessive — compulsive symptoms . Changes in the quality of life were also noted . Repeated measures of analysis of variance ( ANOVA ) tests with Bonferroni corrections were conducted in order to evaluate the data . Symptoms of inattention , hyperactivity and impulsivity were significantly reduced ( p < 0.017 ) following a three-month MPH treatment . There were significant decreases in depression ( p = 0.004 ) , trait anxiety ( p = 0.000 ) and checking compulsion symptom scores ( p = 0.001 ) . Moreover , parents reported significant improvements in psychosocial ( p = 0.001 ) and total scores ( p = 0.009 ) of quality of life , despite no change in physical health scores ( p > 0.05 ) . Children ’s ratings of quality of life measures showed no significant changes in physical health and psychosocial scores ( p > 0.05 ) , while total scores significantly improved ( p = 0.001 ) after the treatment . Over a three-month MPH treatment , depression , trait anxiety and checking compulsion symptoms decreased and quality of life seemed to improve along with those of inattention , hyperactivity and impulsivity
