Previous research indicates that men are affected when their female partners have breast cancer. However, little is known about what predicts men's psychological well-being in this context. The current investigation involved couples in which the woman had early stage breast cancer and explored the degree to which men's positive and negative well-being was related to women's well-being, women's physical symptoms, relationship functioning, and relationship duration. The findings indicate that all of these factors play a role and interact in predicting men's well-being. In particular, when women have a high level of physical symptoms, the typical associations between men's well-being with women's well-being and relationship adjustment no longer persist. Implications for working with couples addressing health problems are provided.  相似文献

Abstract. The strong Rayleigh property is a new and robust negative dependence property that implies negative association; in fact it implies conditional negative association closed under external fields (CNA+). Suppose that and are two families of 0‐1 random variables that satisfy the strong Rayleigh property and let . We show that {Zi} conditioned on is also strongly Rayleigh; this turns out to be an easy consequence of the results on preservation of stability of polynomials of Borcea & Brändén (Invent. Math., 177, 2009, 521–569). This entails that a number of important π ps sampling algorithms, including Sampford sampling and Pareto sampling, are CNA+. As a consequence, statistics based on such samples automatically satisfy a version of the Central Limit Theorem for triangular arrays.  相似文献
