However, this measurement doesn't always replicate the factorial structure theoretically expected, hindering potential conclusions. Aim: To assess the reliability and validity of SF-12 questionnaire in a representative sample of Chilean participants. Material and Methods: Information was obtained from the National Quality of Life Survey performed in Chile during 2015-16. During the survey, SF-12 was answered by 7041 participants older than 15 years, with a median age of 47 years (63% women). Results: SF-12 has reliability, but it does not have construct validity. The analysis suggests that there is a factorial structure that resembles theory, only when factors and items are related. Conclusions: The practical importance of these results highlight the need to measure HRQoL using more extensive scales.info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.148 n.11 20202020-11-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872020001101568es10.4067/S0034-98872020001101568
