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 .
Does resistance training improve the functional capacity and well being of very young anorexic patients? A randomized controlled trial.
PURPOSE We determined the effects of a 3-month low-moderate-intensity strength training program ( 2 sessions/week ) on functional capacity , muscular strength , body composition , and quality of life ( QOL ) in 22 young ( 12 - 16 yrs ) anorexic out patients . METHODS Patients were r and omly assigned to a training or control group  ( n=11 [ 10 females ] each ) . Training sessions were of low intensity ( loads for large muscle groups ranging between 20%-30 % and 50%-60 % of six repetitions maximum [ 6RM ] at the end of the program ) . We measured functional capacity by the time up and go and the timed up and down stairs tests . Muscular strength was assessed by 6RM measures for seated bench and leg presses . We estimated percent body fat and muscle mass . We assessed patients ' QOL with the Short Form-36 items . RESULTS The intervention was well tolerated and did not have any deleterious effect on patients ' health , and did not induce significant losses in their body mass . The only studied variable for which a significant interaction ( group x time ) effect was found ( p=.009 ) was the 6RM seated lateral row test . CONCLUSIONS Low-moderate-intensity strength training does not seem to add major benefits to conventional psychotherapy and refeeding treatments in young anorexic patients
