    MOS-HIV is developed to assess a participant's health and functional status associated with HIV infection. The questionnaire is applied to participants with adequate linguistic skills and consists of 35 items. The questionnaire derives an overall health score and 10 subscale scores (health transitions, pain, physical functioning, role functioning, social functioning, cognitive functioning, mental health, energy/fatigue, health distress and quality of life).The subscale and summary scores range from 0-100 with a higher score indicating better health.
