RESUMEN
INTRODUCTION@#Chronically-ill patients are known to pose an impact on the family function (FF) and quality of life (QoL) of their family caregivers and pediatric siblings. However, there is limited literature on the relationship between FF and QoL. This study aimed to determine the correlation of FF and QoL among healthy young adults with siblings with chronic diseases. @*METHODS@#This was an analytical cross-sectional study among young adults, selected by purposive sampling, with chronically-ill siblings. The CAPGAR and WHOQOL-BREF questionnaires were used for data collection. Spearman’s correlation coefficient r was used to determine the correlation between FF and QoL.@*RESULTS@#More than half (53.9%) of the respondents had highly functional families. Majority of the participants (66.5%) had fair QoL. There was a weak but significant positive correlation (r = 0.27, p < 0.001) between FF and QoL.@*CONCLUSION@#There is a weak but significant positive correlation between family function and quality of life among healthy young adults with a sibling suffering from a chronic debilitating illness.
