Objective The aim of the present study was to consider the trustworthiness and preliminary normative values of the SF-12 v2 in Colombian adults. Method The questionnaire was applied during self-administered interview of 527 people. Central tendency, dispersion and percentile measurement were used for dominions and groups; internal consistency and inter-scale correlation was calculated. Results It was found that the domains exceeded the proposed reliability standard (0.7 Cronbach's Alpha). The highest average mental health scores occurred in the vitality and mental health domains. The highest physical health scores were found in the body pain, physical functioning and general health domains. Inter-scale correlation resulted in an intermediate range (r=0.22-0.84; p <0.01). Conclusions It was found that this version of the SF-12 proved to be a reliable instrument. The normative values will facilitate interpreting HRQOL results assessed by SF of studies in Colombia.
