Field test results are reported for the Observable Indicators of Nursing Home Care Quality Instrument-Assisted Living Version, an instrument designed to measure the quality of care in assisted living facilities after a brief 30-minute walk-through. The OIQ-AL was tested in 207 assisted-living facilities in two states using classical test theory, generalizability theory, and exploratory factor analysis. The 34-item scale has a coherent six-factor structure that conceptually describes the multidimensional concept of care quality in assisted living. The six factors can be logically clustered into process (Homelike and Caring, 21 items) and structure (Access and Choice; Lighting; Plants and Pets; Outdoor Spaces) subscales and for a total quality score. Classical test theory results indicate most subscales and the total quality score from the OIQ-AL have acceptable interrater, test-retest, and strong internal consistency reliabilities. Generalizability theory analyses reveal that dependability of scores from the instrument are strong, particularly by

Scoring guidelines based on the total sample of observations (N = 358) help guide those who want to use the measure to interpret both subscale and total scores. Content validity was supported by two expert panels of people experienced in the assisted-living field, and a content validity index calculated for the first version of the scale is high (3.43 on a four-point scale). The OIQ-AL gives reliable and valid scores for researchers, and may be useful for consumers, providers, and others interested in measuring quality of care in assisted-living facilities.Keywords assisted living; residential care; nursing homes; quality of care; generalizability theory; reliability and validityThe number of assisted living facilities in the United States increased rapidly during the 1990s with an estimated 33,000 facilities caring for approximately 800,000 residents (NCAL, 2001). While the concept of assisted living is not new, having its roots in congregant housing in the 1960s (Pruchno & Rose, 2000), today's assisted-living facilities provide housing and supportive services with some capacity to meet both scheduled and unscheduled health care needs of an older and more frail adult population (Allen, 1999;Brummett, 1997). Today's assisted-living facilities also emphasize the social model of care rather than the medical model of care. Frail older adults and their families are attracted to homelike environments that do not resemble hospitals or traditional nursing homes and that stress independence, autonomy, and continuation of prior lifestyles.Quality of care or life has been only minimally addressed in the slowly growing body of research literature related to assisted-living facilities.
