One of the negative factors that can override the positive factors identified as influencing a college student's decision about STI testing is the "social stigma of having an STI".

In many cases, the social stigma behind the STI testing is more harming than the STI itself since individuals fear what their associates will consider them in the event that they discover that they have it. This frequently makes a psychological and enthusiastic toll, prompting pressure, sorrow and disconnection. In the event that we can change the stigma, individuals won't be so perplexed of getting tried and will feel more secure and more open to unveiling with their companions and accomplices, and thus, we can diminish the spread of STIs all while expanding our consciousness of them.
