The purpose of the study was to assess the psychometric properties of the Medical Outcomes Study Social Support Scale (MOS-19 items) on a Greek sample of people living with HIV/AIDS. The MOS-19 was administered in 140 participants. The second questionnaire that has been used for construct validity of the MOS was the Social Support Questionnaire 6 (SSQ6). Factor analyses have been conducted and MOS was assessed for its validity and reliability. Factor analysis revealed one factor accounted for 68.08% of the variance. The scale showed good construct validity. The internal consistency measured by Cronbach’s alpha was assessed concerning reliability coefficients of the questionnaire showing a good internal consistency (a= 0.97). Overall test–retest reliability was satisfactory at p <0.0005. Concluding, the Greek version of the MOS Social Support Scale is a reliable and valid scale measuring social support of people with HIV and AIDS.
