The Maternal and Partner Sex During Pregnancy Scales (MSP/PSP) are self-report measures of expectant couples' attitudes towards sex during pregnancy.
This study aimed to examine dyadic non-independence of MSP/PSP scores in a sample of expectant couples, while providing an evaluation of factor structure, validity, and reliability of the Portuguese versions of the MSP/PSP. The association between partners' attitudes and frequency of sexual behaviors was also examined.
A total of 189 expectant couples completed a survey that included a sociodemographic questionnaire, the MSP/PSP, frequency of sexual behaviors, as well as validated measures of attitudes to sex, sexual function, sexual satisfaction, depression, and perceived social support.
Dyadic interdependence was tested via Pearson correlation between MSP/PSP scores; between-dyads variability was tested via intraclass correlation of the unconditional model including only MSP/PSP scores using a multi-level model. Associations between attitudes and sexual behavior were tested using regression analysis (between-dyads outcomes) or APIM (mixed outcomes). Factor structure, internal consistency, and validity (convergent, discriminant, and concurrent) of the Portuguese versions of the scales were assessed.
MSP/PSP scores were interdependent within-dyads. Male partners presented significantly more positive attitudes towards sex during pregnancy than pregnant women. Attitudes were linked to indices of sexual well-being for both partners (sexual functioning, sexual satisfaction) and, for both partners, more positive attitudes were associated with higher frequencies of most partnered sexual behaviors. The Portuguese MSP/PSP scales showed good factor structure, and good to excellent indices of reliability and validity.
The Portuguese MSP/PSP is adequate for use in couples. The scales can be used to screen partners with negative attitudes towards sex during pregnancy and evaluate how these attitudes relate to intra- and inter-individual sexual well-being during pregnancy.
STRENGTHS & LIMITATIONS: A strength of this study is the inclusion of both expectant partners and the use of dyadic analysis. Couples who participated in the study were all in mixed-gender/sex relationships, although this was not defined as an inclusion criterion. Future studies should use the MSP/PSP in more diverse samples in order to further determine how the scale performs for couples with different characteristics.
Scores in the MSP/PSP are interdependent between mixed-sex/gender expectant couple members. More positive attitudes towards sex during pregnancy are linked to higher frequencies of partnered sexual behaviors and to both partners' greater sexual well-being.

母婴性孕期量表（MSP/PSP）是一种自我报告的工具，用于评估准父母对孕期性行为的态度。
本研究旨在考察准父母样本中 MSP/PSP 评分的对偶非独立性，同时评估葡萄牙语版 MSP/PSP 的因子结构、效度和信度。还检验了伴侣之间的态度和性行为频率之间的关联。
共有 189 对准父母完成了一项调查，其中包括一份社会人口学问卷、MSP/PSP、性行为频率，以及性态度、性功能、性满意度、抑郁和感知社会支持的验证性测量。
MSP/PSP 评分在对偶内呈相关性；通过仅包含 MSP/PSP 评分的无条件模型的多水平模型测试对偶间变异性的内类相关。使用回归分析（对偶间结果）或 APIM（混合结果）检验态度与性行为之间的关联。评估了葡萄牙语版量表的因子结构、内部一致性和效度（收敛、区分和同时）。
MSP/PSP 评分在混合性别/性别的准父母成员之间是相互依存的。对孕期性行为的态度越积极，与伴侣的性行为频率越高，与伴侣的性健康指数越高（性功能、性满意度），对孕期性行为的态度越积极。Tavares Inês M.、Heiman Julia R.、Rosen Natalie O.、等人。葡萄牙语版母婴性孕期量表（MSP/PSP）的验证：评估对偶相互依存关系及与性行为的关联。J 性医学 Rev 2021;18:789-799。
