Though addictions to substances including alcohol are highly heritable, there have been no studies regarding the possible applicability of genetic counseling to this set of conditions. Adults (≥18 years old) with a personal and/or family history of alcohol addiction were recruited to participate in an online survey-based study comprising 43 questions about beliefs/concern about recurrence risk and etiology of alcohol addiction and its impact on childbearing decisions, and perceptions of potential utility of genetic counseling for alcohol addiction. We applied primarily descriptive statistics, but also tested the hypotheses that perceiving genetic counseling to be useful would be associated with: 1) increasing importance attributed to genetics in the etiology of alcohol addiction, and 2) greater concern about recurrence of alcohol addiction (in self and/or children). Overall, the 113 participants recognized the multifactorial nature of alcohol addiction but reported a wide range of estimated recurrence risks for first-degree relatives. Overall, 62% perceived genetic counseling for alcohol addiction to be potentially beneficial. Participants were more likely to perceive a benefit from genetic counseling if they were concerned about recurrence for themselves (p = .021) or perceived genetics to be etiologically important in alcohol addiction (p = .024). Future studies are warranted to evaluate the outcomes of genetic counseling for addictions with respect to patient understanding, lifestyle modifications and psychological adaptation.
尽管对包括酒精在内的物质成瘾具有高度遗传性,但尚无关于遗传咨询在这类情况中可能适用性的研究。招募有酒精成瘾个人史和/或家族史的成年人(≥18岁)参与一项基于在线调查的研究,该研究包含43个问题,涉及对酒精成瘾复发风险、病因及其对生育决策的影响的信念/担忧,以及对酒精成瘾遗传咨询潜在效用的看法。我们主要应用描述性统计方法,但也检验了以下假设:认为遗传咨询有用与以下情况相关:1)在酒精成瘾病因中对遗传学重视程度增加,以及2)对酒精成瘾复发(自身和/或子女)更为担忧。总体而言,113名参与者认识到酒精成瘾的多因素性质,但报告的一级亲属复发风险估计范围很广。总体而言,62%的人认为酒精成瘾遗传咨询可能有益。如果参与者担心自身复发(p = 0.021)或认为遗传学在酒精成瘾病因中具有重要意义(p = 0.024),他们更有可能认为遗传咨询有益。有必要开展进一步研究,以评估成瘾遗传咨询在患者理解、生活方式改变和心理适应方面的效果。
