现有的测量前列腺癌幸存者性功能的方法主要集中在勃起功能上，没有充分测量性少数男性的经历。开发和心理测量学评估一种新的量表来测量患有前列腺癌的性少数男性的性功能。性少数前列腺癌患者（n = 401）在2019年完成了一系列在线泌尿和性功能测试，其中包括一个新的37项关于前列腺癌治疗后性功能的工具。我们使用验证性因素分析，以确定一个新的规模，包括五个分量表的结构效度：一个四因素模型的所有参与者（n = 401）评估性满意度，性信心，性问题的频率，并在性尿路感染。一个单因素模型完成的参与者谁曾尝试或希望接受肛交（n = 255）进行了评估，在第五分量表：问题接受肛交。为了评估标准的有效性，我们计算了每个性少数和前列腺癌量表（SMACS）子量表和四个相关量表之间的相关性：扩展前列腺癌综合指数-50（EPIC），癌症治疗功能评估-前列腺，简明症状量表-18和国际尿失禁咨询问卷。计算Cronbach α以测量内部一致性（即可靠性）。Cronbach α值范围为0.64 - 0.89。载荷（0.479-0.926）和模型拟合指数较强（近似均方根误差：0.085，标准化均方根残差：0.063，比较拟合指数：0.927，Tucker-Lewis指数：0.907）。对于标准效度，性满意度，性信心，性问题的频率与EPIC功能和困扰评分中度相关（r = 0.50-0.72），性尿失禁与EPIC尿功能和国际尿失禁咨询问卷评分中度相关（0.45-0.56）。SMACS可以被临床医生和研究人员用来综合测量性少数男性的性功能，结合现有的量表。这种新的量表在一个大型的、地理上多样化的性少数癌症幸存者队列中得到了验证，填补了现有性功能指标的一个重要空白。局限性包括缺乏验证样本。SMACS是一个有效和可靠的新尺度，衡量性少数男性的经验，尿失禁的性，有问题的接受肛交，和性痛苦。
Existing measures of sexual functioning in prostate cancer survivors focus primarily on erectile function and do not adequately measure the experiences of sexual minority men. To develop and psychometrically evaluate a new scale to measure sexual functioning among sexual minority men with prostate cancer. Sexual minority prostate cancer patients (n = 401) completed an online battery of urinary and sexual functioning tests in 2019, including a new 37-item instrument about their sexual functioning post-treatment for prostate cancer. We used confirmatory factor analysis to determine the construct validity of a new scale including five subscales: a four-factor model for all participants (n = 401) evaluated Sexual Satisfaction, Sexual Confidence, Frequency of Sexual Problems, and Urinary Incontinence in Sex. A single-factor model completed only by participants who had attempted or desired receptive anal sex (n = 255) was evaluated in the fifth subscale: Problematic Receptive Anal Sex. To evaluate criterion validity, we calculated the intercorrelations between each Sexual Minorities and Prostate Cancer Scale (SMACS) subscale and four related scales: the Expanded Prostate Cancer Index Composite-50 (EPIC), the Functional Assessment of Cancer Therapy-Prostate, the Brief Symptom Inventory-18, and the International Consultation on incontinence questionnaire. Cronbach’s alphas were calculated to measure internal consistency (ie, reliability). Cronbach’s alpha values ranged from 0.64 to 0.89. Loadings (0.479–0.926) and model fit indices were strong (Root Mean Square Error of Approximation: 0.085, Standardized root mean squared residual: 0.063, comparative fit index: 0.927, Tucker-Lewis Index: 0.907). For criterion validity, Sexual Satisfaction, Sexual Confidence, and Frequency of Sexual Problems were moderately correlated with EPIC function and bother scores (r = 0.50–0.72) and Urinary incontinence in sex correlated moderately with EPIC Urinary Function and International Consultation on incontinence questionnaire scores (0.45–0.56). The SMACS can be used by clinicians and researchers to comprehensively measure sexual functioning in sexual minority men, in conjunction with existing scales. This new scale is validated in a large, geographically diverse cohort of sexual minority cancer survivors and fills an important gap in existing measures of sexual functioning. Limitations include a lack of a validation sample. The SMACS is a valid and reliable new scale that measures sexual minority men’s experience of urinary incontinence in sex, problematic receptive anal sex, and sexual distress.
