Men who carry an FMR1 premutation are at-risk to develop a late-onset neurodegenerative disorder called fragile X-Associated Ataxia/Tremor syndrome (FXTAS). However, little is known about their health informational needs. This qualitative study is the first to describe diagnostic experiences and identify specific health information needs of male premutation carriers. In-depth qualitative interviews were conducted by phone with ten men who carry an FMR1 premutation. Interviews were analyzed using direct content analysis. Saturation was assessed through use of the Comparative Method for Themes Saturation in qualitative interviews (CoMeTS). Five themes were identified: diagnosis experience, sources of health information, desired health information, barriers to obtaining health information, and facilitators to desired health information. Participants desired information about inheritance, symptoms, expectations for disease, and actions available to slow progression. Facilitators to obtaining health information included healthcare provider knowledge, positive experiences with providers, beneficial family dynamics, participating in research, and access to experts. Barriers to obtaining health information included lack of personal knowledge, lack of healthcare provider knowledge, negative experiences with providers, and uncertainty. Addressing the educational needs of men with/at-risk for FXTAS could improve the quality of life of men who carry a fragile X premutation.
携带 FMR1 前突变的男性有患上称为脆性 X 相关共济失调/震颤综合征 (FXTAS) 的迟发性神经退行性疾病的风险。然而,人们对他们的健康信息需求知之甚少。这项定性研究首次描述了男性前突变携带者的诊断经历,并确定了他们具体的健康信息需求。通过电话对十名携带 FMR1 前突变的男性进行了深入的定性访谈。使用直接内容分析法对访谈进行了分析。通过使用定性访谈的比较主题饱和度方法 (CoMeTS) 来评估饱和度。确定了五个主题:诊断经历、健康信息来源、所需健康信息、获取健康信息的障碍以及所需健康信息的促进因素。参与者希望了解遗传、症状、对疾病的预期以及可减缓疾病进展的措施。获取健康信息的促进因素包括医疗保健提供者的知识、与提供者的积极互动、有益的家庭动态、参与研究以及获得专家的帮助。获取健康信息的障碍包括个人知识的缺乏、医疗保健提供者知识的缺乏、与提供者的负面互动以及不确定性。满足患有/有风险患上 FXTAS 的男性的教育需求可以提高携带脆性 X 前突变的男性的生活质量。
