The Department of Health (DoH) is considering funding a new intervention for helping younger adolescents (aged 12-15) with self-reported poor sleep, improve their sleep. Inadequate sleep at night in this age group has been shown to be associated with many poor outcomes including reduce capacity to learn (hence poorer grades), behavioural problems and lowered mood. This program is called "Sleeping Well" - a behaviourally based sleep intervention that provides parents with skills to help improve sleep outcomes for their adolescent as well as providing adolescents with strategies to help improve their sleep. Parent(s) and the adolescent will be seen for two x 50 minute consultations conducted two weeks apart, followed by a telephone call two weeks after the second session. The intervention will be delivered by study-employed adolescent psychologists. Session One will focus on an assessment of the adolescent's sleep problems, providing information about normal sleep and sleep cycles, sleep hygiene, and a tailored plan specific to the sleep diagnosis of the adolescent. Session Two will be held two weeks later to reinforce strategies, trouble shoot and monitor progress. Clinicians will then telephone families two weeks after the second visit to reinforce strategies, trouble shoot and monitor progress. The DoH wants to know whether there is evidence that "Sleeping Well" represents "value for money". You have been asked to design a protocol for an economic evaluation alongside a randomised controlled trial of this intervention. Screening to detect eligible participants will include a short questionnaire administered at school. 

Question: To design a well-defined study question we need to compare two intervention. From above information we are going to compare new intervention for helping young adolescents with sleeping problem with an alternative intervention.
