[Reliability and validity of the Spanish version of the MOS-SF-30 to assess the health related quality of life in people infected by HIV].
OBJECTIVE
To assess the psychometric properties of the health related quality of life questionnaire of the Medical Outcomes Study-short form 30 items (MOS-SF-30).


METHODS
Cross sectional study.Setting. Urban university hospital.


METHODS
A hundred HIV+ subjects (28 asymptomatic, 35 symptomatic and 37 with AIDS).


METHODS
HRQoL questionnaire MOS-SF30, clinical (CDC stage) and immunological measures (CD4, viral load). Results. MOS-SF30 questionnaire (Spanish version) presents adequate internal consistency (between 0.84 to 0.91 for the different subescales), yielding also total Cronbach's alpha of 0.93. Concurrent validity has been contrasted through the medical measures. Total punctuation of the scale was able to distinguish the subjects between the different stages of the HIV infection and to distinguish those with an undetectable viral load.


CONCLUSIONS
Spanish version of the MOS-SF-30 seems to be a valid measure for the evaluation of the perceived health status and quality of life in people living with HIV.
