This pilot study is a prospective clinical trial comparing parent knowledge of, and child outcomes for clinically indicated PSG which is part of routine care. Comparisons will take place before and after either educational intervention or usual clinical care preparing children for PSG at KKI. Interested families will be recruited through the Kennedy Krieger Institute (KKI) Sleep Disorders Clinic and flyers will be distributed to other KKI subspecialty clinics in which clinically indicated PSG may be ordered. Families for whose children PSG is clinically recommended in KKI Sleep Disorders Clinic will have informed consent obtained from parents and assent from children in clinic, and randomization will occur at that time. Alternately, families for whose children PSG is clinically recommended in that clinic or others may contact the research coordinator for phone screening (telephone script attached) in order to be consented and assented; randomization will then take place once informed consent is received. Families randomized to the educational story intervention group will receive a printed copy of the educational story, as well as instructions on how to use it. Families randomized to the standard clinical care group will receive a set of pictures used in standard clinical care without an accompanying educational story.
