Psychometric Evaluation of the 12-Item HIV Stigma Scale among People Living with HIV (PLHIV) on Antiretroviral Therapy (ART) in Mizoram, India

HIV is a virus that attacks the body's immune system, but for the millions of people living with it around the world, the virus is often not the only thing they must fight. A powerful, invisible force known as stigma frequently stands in the way of their health and happiness. Stigma is the deep shame, fear, and judgment that society places on someone simply for having the virus. It shows up in many ways: as friends who stop calling, as neighbors who refuse to shake a hand, or as the quiet, heavy feeling inside a person that they are somehow less worthy than others. This shame can be so overwhelming that people hide their status, avoid doctors, or stop taking the medicine that keeps them alive. To help these individuals, researchers need a way to measure this invisible burden accurately. They need a tool that can capture the different shapes of this shame, from the fear of being rejected to the internal belief that one is a bad person, so that programs can be designed to lift it.

In the northeastern state of Mizoram, India, where the rate of HIV infection is higher than anywhere else in the country, a team of researchers set out to test a specific tool for measuring this burden. The state is home to tight-knit communities where family reputation and religious values shape daily life, making the fear of being discovered particularly intense. The researchers focused on 254 adults who were already receiving treatment for HIV. They wanted to see if a shortened version of a well-known questionnaire, the 12-item HIV Stigma Scale, would work well in this specific cultural setting. The original version of this questionnaire had 40 questions, which could be too long and tiring for busy patients, so a shorter version was created by selecting just three questions for each of the four main types of stigma. The team asked these patients to answer the 12 questions while also sharing how they felt about their mental health, including whether they felt depressed, hopeless, or lost in their lives.

The study found that the short questionnaire worked remarkably well. When the researchers looked at the answers, they saw that the 12 questions naturally grouped themselves into four distinct categories, just as the original theory had predicted. The first group captured the worry that people would treat them poorly if they found out, such as being called "dirty" or treated like an outcast. The second group measured the direct consequences of people they knew pulling away, like losing friends or being avoided. The third group focused on the secret-keeping, the intense effort to hide the diagnosis from everyone. The fourth group measured the internal pain, the guilt and shame that made people feel they were not as good as others. The data showed that these four areas were clear and separate from one another, yet they all fit together to form a complete picture of the stigma experience. The questions were consistent, meaning that if a person felt a certain way about one aspect of stigma, they tended to feel similarly about the other questions in that same group.

Beyond just checking if the questions made sense, the researchers looked at how these feelings of stigma connected to the patients' mental well-being. They discovered a clear link between the weight of stigma and the struggle with mental health. People who reported higher levels of stigma, especially the kind that made them feel guilty or ashamed of themselves, were also more likely to report feeling depressed or feeling that life had lost its meaning. The connection was not just a vague feeling; the data showed that as the sense of shame grew, so did the feelings of helplessness and the loss of purpose. This confirmed that the scale was not just counting words on a page, but was actually measuring a real, painful experience that affects how people live. The researchers also checked that the tool was reliable enough to be used in future studies, finding that it performed with the same strength as it has in studies conducted in other parts of the world, including Sweden.

The findings suggest that this short, 12-question tool is a powerful and practical way to understand the hidden struggles of people living with HIV in Mizoram. Because the questionnaire is brief, it can be easily used by doctors and community workers during routine visits without taking up too much time. This allows them to quickly identify who is carrying the heaviest burden of shame and who might need extra support. The study highlights that in a place like Mizoram, where community ties are strong, the fear of being discovered is a major barrier to health. By using this tool, health workers can better understand the specific fears their patients face, whether it is the fear of losing friends or the fear of being judged by society. Ultimately, the research shows that measuring stigma is not just an academic exercise; it is a necessary step toward improving the lives of people living with HIV, helping them stay on their treatment, and ensuring they can live with dignity and hope.
