ABSTRACT

The chapter introduces readers to innovative measurement practices and the wide range of applications of the Rasch model across the human sciences. For many in the human sciences, structural equation modeling (SEM) has become the instrument of choice. For those who are more thoughtfully wedded to SEM, author's advice would be spread over two steps: First, that Rasch analysis should be adopted to guide the construction and quality control of measurement scales for each of the variables that feature in the research. Second, that the interval-level person Rasch measures and their standard errors (SEs) that derive from each of those instruments should be imputed into the SEM software for the calculation of the relationships between those variable measures. The strong Rasch measurement properties of the family strain questionnaire-short form (FSQ-SF) and innovative scale representation mean that nurses and general practitioners can use it to routinely scan for increased strain in the caregivers of their long-term patients.
