The primary goal of this observational study is to investigate the relationship between perceived stigma and social support in HIV+ patients. The secondary objective is to measure mental health indicators (depression, anxiety, and stress) and quality of life to assess whether they are affected by the relationship between perceived stigma and social support.

The main questions it aims to answer are:

• Measuring perceived stigma and social support to understand the health status and behaviour of people living with HIV.
• Monitor the mental state of people living with HIV in order to be able to implement, there where necessary, a psychological support strategy in order to promote proper adherence to treatment and care services.

• sociodemographic and clinical data related to HIV infection,
• perceived stigma,
• social support,

We expect the majority of the HIV patient population to be male, between the ages of 40 and 65 and with a high school diploma. We expect a virologically suppressed HIV population with good adherence to antiretroviral therapy. We expect a high level of perceived stigma and low quality of life and high symptoms of depression, anxiety and stress.
