Understanding the psychological impact of identifying carrier status on young adults: A qualitative study exploring peer reactions

The benefits and harms of identifying carriers in childhood have long been debated with European Guidelines advising against this practice. Yet over a thousand carriers are identified via newborn bloodspot screening per year in the United Kingdom alone. One of the concerns about identification is the impact it has on an individual's identity. This, in part, will be determined by how parents and peers view carriers, particularly during young adulthood. To address the paucity of research looking at how carriers are perceived by peers, this study sought to explore the views of young adults, who themselves are not carriers, toward carriers. As the narratives around COVID-19 increased, the salience of the term "carrier", the impact of such narratives on perceptions, was also explored. Twenty-five 18-25 year olds participated in a diary-interview study in the United Kingdom during 2021 to explore their perceptions of carriers via hypothetical scenarios. Data were analyzed using thematic analysis. Interviewees believed carriers would experience stigma-including societal and self-stigma. This was because people used existing illness beliefs to make sense of carrier status about which they had low levels of understanding. Interviewees believed carriers would experience challenges in familial and romantic relationships due to others' judgments. They also believed parents of carriers would experience a burden around making reproductive decisions, with clear views on what society would view as acceptable choices. Importantly interviewees felt knowledge of ones' own carrier status conferred complex communication challenges within relationships. These findings suggest an urgent need for more research and support for young adults entering a key stage in life for identity formation who have knowledge of their carrier status. The results suggest that support targeted toward the carrier regarding navigating complex communication and targeted more broadly to avoid stigma based on misunderstanding should be researched and developed.
