Using a sample of 45 women, this study compared the effectiveness of a previously studied (Mintz, Balzer, Zhao, & Bush, 2012) bibliotherapy intervention (Mintz, 2009), a similar self-help book (Hall, 2004), and a wait-list control (WLC) group. To examine intervention effectiveness, between and within group standardized effect sizes (interpreted with Cohen's, 1988 benchmarks .20 = small, .50 = medium, .80+ = large) and their confidence limits are used. In comparison to the WLC group, both interventions yielded large between-group posttest effect sizes on a measure of sexual desire. Additionally, large between-group posttest effect sizes were found for sexual satisfaction and lubrication among those reading the Mintz book. When examining within-group pretest to posttest effect sizes, medium to large effects were found for desire, lubrication, and orgasm for both books and for satisfaction and arousal for those reading the Mintz book. When directly comparing the books, all between-group posttest effect sizes were likely obtained by chance. It is concluded that both books are equally effective in terms of the outcome of desire, but whether or not there is differential efficacy in terms of other domains of sexual functioning is equivocal. Tentative evidence is provided for the longer term effectiveness of both books in enhancing desire. Arguing for applying criteria for empirically supported treatments to self-help, results are purported to establish the Mintz book as probably efficacious and to comprise a first step in this designation for the Hall book.
本研究以45名女性为样本，比较了之前一项研究（明茨、巴尔泽、赵和布什，2012年）中的阅读疗法干预措施（明茨，2009年）、一本类似的自助书籍（霍尔，2004年）以及一个等待名单对照组（WLC）的效果。为检验干预效果，使用了组间和组内标准化效应量（根据科恩1988年的标准进行解释，.20为小效应，.50为中等效应，.80及以上为大效应）及其置信区间。与等待名单对照组相比，两种干预措施在性欲测量上均产生了较大的组间后测效应量。此外，阅读明茨书籍的人群在性满意度和润滑方面也发现了较大的组间后测效应量。在检验组内前测到后测的效应量时，两本书在性欲、润滑和性高潮方面均发现了中等至较大的效应，而阅读明茨书籍的人群在满意度和性唤起方面也有此类效应。当直接比较这两本书时，所有组间后测效应量可能是偶然获得的。研究得出结论，就性欲结果而言，两本书同样有效，但在性功能的其他领域是否存在差异疗效尚不清楚。初步证据表明两本书在增强性欲方面具有长期有效性。主张将实证支持治疗的标准应用于自助，据称结果确立了明茨的书可能有效，并构成了将霍尔的书指定为可能有效的第一步。
