Abstract Objective: The purpose of this study is the validation of a proposed additional item for the PWI-7 scale for measuring sexual satisfaction as a dimension of Personal Well-being. Methodology: An adaptation of the PWI-7 questionnaire was administered to adult inhabitants of urban areas of Santiago, Chile. Analysis consisted of exposition of descriptive statistics, item-scale correlation, item-item correlation, multiple linear regression with the Overall Life Satisfaction Scale (OLS), moderation analysis and, confirmatory factor analysis. All analyses were divided by gender due to significant differences in sexual satisfaction found in literature reviewed. Results: All items were significantly and positively associated with the PWI. Internal consistency was satisfactory for Cronbach’s alpha (α = 0.884 for males and α = 0.877 for females). After conducting a Confirmatory Factor Analysis using maximum likelihood (ML) as estimator, adequate levels of adjustment were obtained. Discussion: Results indicate that adding a new item on sexual satisfaction might be a contribution for the measurement of life satisfaction. The scale shows adequate internal consistency once the item is added and the new item on sexual satisfaction has a better fit than the one regarding satisfaction with spiritual life. Factor structure was invariant for males and females.

性幸福指数（PWI-Sex）的验证

摘要目的：本研究的目的是验证一项提议的PWI-7量表的附加项目，该量表用于测量性满意度作为个人幸福感的一个维度。方法：对智利圣地亚哥市区的成年居民进行了PWI-7问卷的改编。分析包括描述性统计数据，项目规模相关性，项目-项目相关性，带有总体生活满意度量表（OLS）的多元线性回归，中度分析和确认性因素分析。所有分析均按性别进行了归类，原因是所审查文献中发现的性满意度差异很大。结果：所有项目均与PWI显着正相关。Cronbach's alpha的内部一致性令人满意（男性为α= 0.884，女性为α= 0.877）。在使用最大似然（ML）作为估计量进行确认性因素分析后，获得了足够的调整水平。讨论：结果表明，添加有关性满意度的新项目可能有助于衡量生活满意度。该量表显示，一旦增加了一项内容，内部就具有足够的一致性，而关于性满意度的新项目比对精神生活的满意度更合适。男性和女性的因素结构不变。该量表显示，一旦增加了一项内容，内部就具有足够的一致性，而关于性满意度的新项目比对精神生活的满意度更合适。男性和女性的因素结构不变。该量表显示，一旦增加了一项内容，内部就具有足够的一致性，而关于性满意度的新项目比对精神生活的满意度更合适。男性和女性的因素结构不变。
