The OIQ instrument was field tested in 400 nursing homes in Missouri and Wisconsin by registered nurses. After extensive testing, the Observable Indicators of Nursing Home Care Quality Instrument has been reduced to 30 reliable and discriminating items that have a conceptually coherent hierarchical factor structure that describes nursing home care quality. The factors are communication, care delivery, grooming, odor, environment-basic, environment-access and environmenthomelike.
The OIQ instrument as a whole shows acceptable interrater and test-retest reliabilities, and strong internal consistency. Scale subscales show acceptable reliability. Generalizability Theory analyses revealed that dependability of scores can be improved by including a second site observer, or by revisiting a site. There is little additional benefit from increasing observers or visits beyond two.
Construct validity analyses revealed an association between survey citations and nearly every subscale as well as the total score of the OIQ instrument. The nursing home version of the instrument has the ranges of each factor in addition to the total ranges so that the scores can be interpreted. The instrument can be used in quality improvement programs in nursing homes.Download Instrument PDF
