Indiana University-Purdue University Indianapolis (IUPUI) / Type 2 diabetes, a chronic condition affecting millions, continues to rise in epidemic proportions. Type 2 diabetes, managed through lifestyle changes, affects the entire family. Family caregivers provide vital support to these individuals; however, little research has been conducted surrounding the perceived difficulty or ease of caregiver activity and supportive behaviors. The purpose of this dissertation was to develop and psychometrically test a scale that measures this difficulty or ease of activities and behaviors. This was accomplished through the compilation of three distinct manuscripts. First, an integrative review was conducted to identify what is known regarding needs and concerns of family caregivers of persons with type 2 diabetes; findings revealed a need for more research. Then, based on these recommendations, a qualitative study was conducted that explored the needs and concerns identified by 33 American Indian, African American, and White family caregivers. All these caregivers had similar concerns related to needing general diabetes information, providing support to the family member, and taking care of their own health. Study themes were used to develop items for a new instrument, the Diabetes Caregiver Activity and Support Scale (D-CASS) that was psychometrically tested with 101 American Indian, African American, and White family caregivers of persons with type 2 diabetes. This study used a cross-sectional, descriptive-correlational design and provided evidence of internal consistency reliability (α = .82) and two-week test-retest reliability (intraclass correlation coefficient = .70) for the D-CASS. Criterion-related validity was established using a single-item criterion measuring overall how easy or difficult it was for caregivers to provide care for their loved ones (r = .65, p < .01). Unidimensionality was supported by factor analysis, with loadings ranging from .45 to .70, with 32% of the variance explained by the first factor (eigenvalue = 4.02). Model testing through a series of three hierarchical multiple regressions guided by a conceptual model provided further evidence of construct validity for the D-CASS. This dissertation provided better understanding of needs and concerns of family caregivers of persons with type 2 diabetes and led to the development of a psychometrically sound diabetes-specific instrument for future research.
