We examined whether dispositional optimism relates to change in global quality of life (QOL) as a function of either chronological age or years to impending death. We used a sample of 2,096 deceased postmenopausal women from the Women's Health Initiative clinical trials who were enrolled in the 2005-2010 Extension Study and for whom at least 1…

In this paper we suggest a way to measure the well-being of society based upon our own development of the Social Quality model. The Social Quality model has the advantage of being sociologically grounded as a measure of the well-being of society and the individuals within it. We test our model of Social Quality against life satisfaction as an…

There is ample evidence that children born to poorer families do not succeed at the same rate as children born to the middle class. On average, low-income children lag behind on almost every cognitive, behavioral, emotional, and health measure. These gaps start early--some of the newest research suggests that cognitive gaps are detectable in…

Introduction: The adult population is increasingly experiencing one or more chronic illnesses and living with such conditions longer. The Chronic Disease Self-Management Program (CDSMP) helps participants cope with chronic disease-related symptomatology and improve their health-related quality of life. Nevertheless, the long-term effectiveness of…

There is considerable debate in the area of individual quality of life research regarding the factor structure of the QOL construct that is focused on the number and composition of QOL factors and domains, and its hierarchical nature. The main goal of this study involve testing by means of confirmatory factor analyses five models that have been…

The purpose of this study was to employ complexity theory as a theoretical framework and technology to facilitate the development of a life-long learning model for non-working time in the interdependent homes for adults with Autism Spectrum Disorders (ASD). A "Shining Star Sustainable Action Project" of the ROC Foundation for Autistic…

Most computerized adaptive tests (CAT) have been studied under the framework of unidimensional item response theory. However, many psychological variables are multidimensional and might benefit from using a multidimensional approach to CAT. In addition, a number of psychological variables (e.g., quality of life, depression) can be conceptualized…

This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

Bifactor and second-order factor models are two alternative approaches for representing general constructs comprised of several highly related domains. Bifactor and second-order models were compared using a quality of life data set (N = 403). The bifactor model identified three, rather than the hypothesized four, domain specific factors beyond the…

Purpose: To describe the development of a model for estimating the effects of tobacco use upon Quality Adjusted Life Years (QALYs) and to estimate the impact of tobacco use on health outcomes for the United States (US) population using the model. Method: We obtained estimates of tobacco consumption from 6 years of the National Health Interview…

The majority of body image measures have largely been developed with younger female samples. Before these measures can be applied to men, and to middle-aged and older women, and used to make gender and age comparisons, they must exhibit adequate cross-group measurement invariance. This study examined the age and gender cross-group measurement…

Increasing demands on academic work have resulted in many academics working long hours and expressing dissatisfaction with their working life. These concerns have led to a number of faculties and universities adopting workload allocation models to improve satisfaction and better manage workloads. This paper reports on a study which examined the…

This paper examines the role that comparative analysis and global policy studies can play in explaining the human condition in the contemporary world. It investigates economic well-being, one dimension of the human condition, and examines some of the attributes that represent it and some of the forces that affect it in villages, social groupings,…

Recent projects on international instrument development have produced a wide array of health indicators that may be used for cross-cultural field-testing, however more information on their cross-cultural performance in relation to health determinants is necessary. The current study approaches one step for international conceptual validation by…

Explaining the use of overlay methodology in the assessment of rural social service this paper describes a technique of visual juxtaposition wherein information is matched with geographic location. To ascertain whether senior citizen centers are located in areas of client concentration, for example, this model superimposes the location of senior…
