According to recent estimates, around 30 million people have taken Direct-to-Consumer DNA ancestry tests, typically marketed as a fun, harmless and exciting process of discovery. These tests estimate a user's ethnic ancestry, also matching users with biological relations on their database. This matching can produce a surprising 'not parent expected' discovery, where a user learns that an assumed parent (typically the father) is not a biological parent. Such news may negatively affect mental health, self-identity and familial relationships, while prompting the utilization of putatively helpful resources by affected individuals. However, there is a lack of research on this topic. Thus, this study aimed to document the psychosocial experience of adults who have learnt that an assumed parent is not a biological parent via a Direct-to-Consumer DNA ancestry test. Specific objectives include investigating and understanding impact on mental health, familial relationships and subsequent resources mobilized.
To meet these objectives, we conducted an inductive qualitative study, allowing for the documentation of common experiences and perspectives. This involved 52 semi-structured interviews with affected individuals, analyzed using thematic analysis.
This resulted in five overlapping themes, namely (i) participants typically described their experience as an extraordinary shock that had a negative impact on their mental health, with some exceptions; (ii) the experience typically led to a severe and troubling disruption of their self-identity, with some exceptions; (iii) the news often ruptured extant familial relationships, especially with the mother, and any experiences with the new biological family were mixed; (iv) participants sought support from a variety of resources including spouses, siblings, and online peer support groups, which were generally considered helpful, with some exceptions; and (v) many participants consulted mental health professionals, who were sometimes considered supportive, but some participants noted that they were ill-equipped to help. Common across these themes were issues of grief, loss and trauma.
This study reveals an expanding, vulnerable, and under-researched population facing unique stressors, that may be at high risk of developing a psychiatric disorder. There is a need for new services and supports for this population including tailored clinical interventions and specific self-care resources.
根据最近的估计,约有3000万人进行了面向消费者的DNA血统检测,这类检测通常被宣传为一个有趣、无害且令人兴奋的探索过程。这些检测会估计用户的种族血统,还会在其数据库中为用户匹配生物学亲属。这种匹配可能会带来令人惊讶的“非父/母预期”发现,即用户得知假定的父母(通常是父亲)并非生物学意义上的父母。此类消息可能会对心理健康、自我认同和家庭关系产生负面影响,同时促使受影响的个体利用一些被认为可能有帮助的资源。然而,关于这一主题的研究尚缺。因此,本研究旨在记录那些通过面向消费者的DNA血统检测得知假定父母并非生物学父母的成年人的心理社会经历。具体目标包括调查和了解对心理健康、家庭关系以及后续所动用资源的影响。
为实现这些目标,我们开展了一项归纳性定性研究,以便记录常见的经历和观点。这涉及对52名受影响个体进行半结构化访谈,并采用主题分析法进行分析。
研究得出了五个相互重叠的主题,即:(i)参与者通常将自己的经历描述为一种非同寻常的冲击,对其心理健康产生了负面影响,但也有一些例外情况;(ii)这种经历通常会导致其自我认同受到严重且令人困扰的干扰,不过也有一些例外;(iii)该消息常常破坏现有的家庭关系,尤其是与母亲的关系,而与新的生物学家庭的任何经历则好坏参半;(iv)参与者从包括配偶、兄弟姐妹以及在线同伴支持小组等各种资源中寻求支持,这些通常被认为是有帮助的,但也有一些例外;(v)许多参与者咨询了心理健康专业人员,他们有时被认为提供了支持,但一些参与者指出他们并不具备足够的能力提供帮助。这些主题中普遍存在悲伤、失落和创伤等问题。
本研究揭示了一个不断扩大、易受伤害且研究不足的人群,他们面临着独特的压力源,可能有患精神疾病的高风险。需要为这一人群提供新的服务和支持,包括量身定制的临床干预措施和特定的自我护理资源。
