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 .
Managing sleep problems in school aged children with ADHD: a pilot randomised controlled trial.
OBJECTIVE To evaluate the feasibility and helpfulness of a behavioral sleep program for children with ADHD , and explore the impact of different program dosages on child and family outcomes . METHODS R and omised trial comparing a brief ( 1 session , n=13 )  and extended ( 2 - 3 sessions , n=14 )  sleep program in children with ADHD ( aged 5 - 14 years ) and at least one behavioral sleep disorder ( American Academy of Sleep Medicine Criteria ) . Outcomes included helpfulness and use of interventions , child sleep ( parent-reported sleep problem ; Child Sleep Habits Question naire ) , ADHD symptoms ( ADHD IV Rating Scale ) , daily functioning ( Daily Parent Rating of Evening and Morning Behavior ) , quality of life ( Pediatric Quality of Life Inventory ) , and caregiver mental health ( Depression Anxiety Stress Scales ) . RESULTS Twenty-seven families ( 63 % of those eligible ) took part . Most parents would recommend the program to others ( 95 % ) and found the strategies helpful . Five months post-r and omisation , 67 % of parents in both groups reported that their child 's sleep problems had resolved . Child quality of life , daily functioning , and parental anxiety also improved in the extended group only ( Cohen 's d : 0.39 , 0.47 and 0.50 , respectively ) . There was minimal change in ADHD symptom scores from baseline to 5 months in either group . CONCLUSIONS A behavioral sleep intervention in children with ADHD is feasible to deliver and improves child sleep by parent report . The extended program result ed in greater improvements in child and caregiver outcomes
