Factor structure of the geriatric institutional assessment profile's professional issues scales.

The Geriatric Institutional Assessment Profile (GIAP) is a self-administered survey of hospital nurses, designed to assess a hospital's readiness to implement geriatric programs. A sample of 2,211 direct care RNs in 24 hospitals was randomly split in half to analyze the Geriatric Professional Issues scales of the GIAP, using one sample for exploratory factor analysis and one for confirmatory factor analysis. An exploratory factor analysis of the six Geriatric Professional Issue scales (staff disagreement, staff/family/patient disagreement, use of geriatric services, perceived legal vulnerability, perceived upsetting behaviors, and burden of upsetting behaviors) demonstrated very good internal consistency both as a whole (Cronbach's alpha coefficient = 0.90) and as individual factors (0.94, 0.91, 0.92, 0.89, 0.85, and 0.81, respectively). The six factors were validated in a half randomly selected sample, with a root-mean-square error of approximation fit index of 0.07 and the normed and non-normed fit indices both 0.8, all indicating adequate fit of the six-factor model.
