Stress, hope, and well-being of women caring for family members with Alzheimer's disease.

The article describes a study that tested a midrange model of caregiver stress mediation in women caring for a family member with Alzheimer's disease. The study was grounded in the nursing theory of modeling and role modeling and tested two hypotheses based on theoretically derived propositions. A convenience sample of 88 female caregivers participating in a larger study completed measures of perceived stress, hope, and well-being. Significant correlations among the three variables occurred in the expected directions. Hope was found to mediate the relationship between stress and well-being, providing tentative support for the theoretically proposed linkages.

Explicating middle-range theory through methodological diversity.

Debates about methodological diversity and the most appropriate paradigm for scientific inquiry are still flourishing within the community of nurse scholars. Rather than continuing to debate these controversies, the authors of this article suggest that nurse researchers set aside methodological differences and move to discover the truths that will build the foundational base of nursing practice and, thus advance the discipline. This article discusses the multiple methodological perspectives used to explicate middle-range concepts from the theory and paradigm for nursing, Modeling and Role-Modeling. Each author will demonstrate how combining different approaches and methodologies can be helpful in exploring and validating middle-range concepts.

Theory-testing research: building the science.

Lack of emphasis on the empirical validation of nursing models has hindered the development of nursing science. This article explores issues concerning theory development in nursing and criteria for evaluating theory-testing research. From a comprehensive review of the literature on theory testing, 15 criteria are identified as essential for evaluating theory-testing studies. The criteria are applied to selected research reports, and recommendations for future use of criteria are suggested.

Stress mediation in caregivers of cognitively impaired adults: theoretical model testing.

The purpose of the study was to test a midrange model of caregiver stress mediation based on Modeling and Role-Modeling theory. Perceived support and self-worth were examined to determine if these self-care resources had a mediating effect between stress and well-being in caregivers of cognitively impaired adults. The sample of 117 caregivers completed measures of basic need status, perceived support, self-worth, stress, and well-being. There were significant correlations among the study variables in the expected directions. Resources mediated the relationship between stress and well-being, providing tentative support for theoretically proposed linkages.

Qualitative study of women's reports of family adaptation pattern four years following transition to parenthood.

This prospective qualitative study examined patterns of family adaptation over 4 years following the birth of a first child. Data were collected on 16 first-time mothers during their second trimester of pregnancy, at 4 months, 1 year, and 4 years after the birth of the infant. Both standard measures and an intensive semistructured interview were used to assess change in women's perceptions of marital adaptation and role reorganization. Using a case-study method, data were analyzed for patterns of family adaptation. Interview data showed that marital distress and later family disorganization patterns were related, in part, to the changes in the marital system starting during the early transition to parenthood, suggesting that subjects' negative perceptions of marital satisfaction as early as 4 months postbirth forecasted later family adjustment problems. Socioeconomic stress and substance use was associated with the changes for some of these subjects. Alternative interpretations and future directions for study are discussed.
