Passive behaviors (PB) are manifested by reductions in cognition, decreased ability to experience or display emotions, and fewer interactions with the environment, and are experienced by 61-88% of nursing home residents with dementia. The purpose of this study was to evaluate the reliability and validity of a new instrument, the Observational Form of the Passivity in Dementia Scale (O-PDS) which was configured for rating videotaped data using the computerized software program, the Noldus Observer 4.o. Twenty-eight videotaped observations of 20 minute time and event samples of 5 female nursing home residents (Mean age 85, mean MMSE 9.62) were coded by 3 trained raters blinded to the study hypotheses. Chronbach's alpha for the overall instrument was .71 indicating adequate internal consistency reliability. Correlations among the five subscales of the instrument were positive and ranged from .05 to .58. Three of the 10 correlations were under .15 indicating discriminant validity for the subscales. Although all 5 subscales reflect passivity, they indicate different aspects of the phenomenon. Distinctiveness of subscales was also suggested by differences in the means on the 5 subscales (range 18.3 to 75.7). Higher levels of percent time passive were present on thinking, emotions, and activities subscales than on interacting with people and the environment. The overall level of percent time passive (51%)and the relative overall scores on subscales tended to be stable across events and times. These preliminary results suggest that the instrument can capture passivity in time and event videotaped data and that further studies with larger samples and additional tests of reliability and validity are warranted.
