Research indicates that marriage equality legislation is associated with improved mental health outcomes for lesbian, gay, bisexual, transgender, and queer (LGBTQ) people. However, the public debate that often precedes such legislation may exacerbate psychological distress and minority stress. In 2017, the Australian Federal Government conducted a national survey to gauge support for marriage equality. The present study investigated the mental health of a sample of LGBTQ people during and after this survey period. A sample of 2,220 LGBTQ participants completed measures of psychological distress and minority stress during the survey period. Participants were invited for follow-up 1 week, 3 months, and 12 months after the postal survey results were announced. Data were analyzed using linear mixed models to evaluate change in psychological distress and minority stress across time points, and the influence of exposure to the marriage equality debate, sexual identity, and gender identity on psychological distress and minority stress. Reported symptoms of psychological distress and minority stress significantly decreased following the postal survey period. Greater exposure to the marriage equality campaign was associated with greater psychological distress and perceived stigma but not internalized stigma. Sexual and gender identity subgroups significantly differed on outcome variable means. This study documents the longitudinal effects on a minority group of a public vote and the enactment of legislation regarding their human rights. The results suggest the postal survey served as a significant stressor to Australia's LGBTQ community. Implications for policy and clinical practice are discussed.

心理健康，少数群体压力和澳大利亚婚姻法邮政调查：一项纵向研究。

研究表明，婚姻平等立法与改善女同性恋，男同性恋，双性恋，变性者和同性恋者（LGBTQ）的人的心理健康状况相关。但是，经常在此类立法之前进行的公开辩论可能会加剧心理困扰和少数群体的压力。2017年，澳大利亚联邦政府进行了一项全国调查，以评估对婚姻平等的支持。本研究调查了在此调查期间和之后的LGBTQ人群样本的心理健康状况。在调查期内，共有2220名LGBTQ参与者样本完成了心理困扰和少数群体压力的测量。在公布邮政调查结果后的1周，3个月和12个月，邀请参与者进行随访。使用线性混合模型分析数据，以评估各个时间点的心理困扰和少数群体压力的变化，以及婚姻平等辩论，性身份和性别认同的暴露对心理困扰和少数群体压力的影响。在邮政调查期之后，报告的心理困扰和少数群体压力症状显着减少。更大程度地参加婚姻平等运动会带来更大的心理困扰和可耻的污名，而不是内在的污名。性和性别认同亚组的结果变量均值存在显着差异。这项研究记录了公众投票对少数群体的纵向影响以及有关其人权的立法的制定。结果表明，邮政调查是澳大利亚LGBTQ社区的重要压力。讨论了对政策和临床实践的影响。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
