Summary
Ten narrative studies involving family histories of 262 children of gay fathers and lesbian mothers were evaluated statistically in response to Morrison's (2007) concerns about Cameron's (2006) research that had involved three narrative studies. Despite numerous attempts to bias the results in favour of the null hypothesis and allowing for up to 20 (of 63, 32%) coding errors, Cameron's (2006) hypothesis that gay and lesbian parents would be more likely to have gay, lesbian, bisexual or unsure (of sexual orientation) sons and daughters was confirmed. Percentages of children of gay and lesbian parents who adopted non-heterosexual identities ranged between 16% and 57%, with odds ratios of 1.7 to 12.1, depending on the mix of child and parent genders. Daughters of lesbian mothers were most likely (33% to 57%; odds ratios from 4.5 to 12.1) to report non-heterosexual identities. Data from ethnographic sources and from previous studies on gay and lesbian parenting were re-examined and found to support the hypothesis that social and parental influences may influence the expression of non-heterosexual identities and/or behaviour. Thus, evidence is presented from three different sources, contrary to most previous scientific opinion, even most previous scientific consensus, that suggests intergenerational transfer of sexual orientation can occur at statistically significant and substantial rates, especially for female parents or female children. In some analyses for sons, intergenerational transfer was not significant. Further research is needed with respect to pathways by which intergenerational transfer of sexual orientation may occur. The results confirm an evolving tendency among scholars to cite the possibility of some degree of intergenerational crossover of sexual orientation.
摘要
進行了對262位男同性戀父親和女同性戀母親子女的十項敘事研究進行統計評估，以回應對Morrison（2007）對Cameron（2006）研究的擔憂，該研究涉及三項敘事研究。儘管多次嘗試使結果偏向於零假設並允許多達 20 個（共 63 個，佔 32%）編碼錯誤，但證實了Cameron（2006）的假設，即同性戀父母更有可能擁有同性戀、女同性戀、雙性戀或不確定（性取向）的兒子和女兒。同性戀父母子女中採用非異性戀身份的比例介於16％至57％之間，具體數據取決於子女和父母性別的組合，相應的勝算比為1.7至12.1。女同性戀母親的女兒最有可能（33％至57％；勝算比從4.5至12.1）報告非異性戀身份。對同性戀父母養育子女的民族志資料和以前的研究進行了重新檢視，並發現支持一個假設，即社會和父母的影響可能會影響非異性戀身份和/或行為的表達。因此，從三個不同的來源提供了證據，與大多數先前的科學觀點，甚至先前的科學共識相反，這表明性取向的代際傳遞可能以統計上顯著且重要的比率發生，尤其是對於女性父母或女性子女。對於兒子的一些分析中，代際傳遞並不顯著。需要進一步研究性取向的代際傳遞途徑。研究結果證實了在學者們之間出現了一種趨勢，即認為性取向在不同世代間可能存在某種程度的互相影響。
