The Pittsburgh Sleep Quality Index (PSQI) is a widely used measure of sleep quality in adolescents, but information regarding its psychometric strengths and weaknesses this population limited. In particular, questions remain whether it measures one or two domains. aims the present study were to (a) adapt PSQI for use adolescents young adults, (b) evaluate properties adapted population. was slightly modified make more appropriate youth populations translated into Spanish administration sample available investigators. It then administered with validity criterion community-based adults (AYA) between 14 24 years old (N = 216). results indicated that questionnaire (AYA-PSQI-S) assesses single factor. total score evidenced good convergent divergent moderate reliability (Cronbach's alpha .72). AYA-PSQI-S demonstrates adequate clinical trials involving adults. Additional research further settings warranted.
