The degree of PADL dependence is markedly lower than in the study of geriatric female inmates carried out by a designer of the instrument.
The findings revealed that PADL score was much more frequently--and strongly--correlated with other variables examined in the study than were chronological age or any other background factors such as race or length of time spent in prison.
Because of its correlation with a diverse set of variables in this study, PADL proved to be a useful tool to distinguish a subgroup of aged inmates with multiple concurrent needs.
PADL is a simple means to assess function and could serve as an index of multiple impairments.
For example, PADL measures require the rater to categorize independent functioning in broad, global areas such as "dressing," but do not acknowledge assistance the caregiver may provide to maintain independent functioning in a person with CI (e.
In a similar study, Kiyak, Teri, and Borson compared self-reports by healthy elders and elders with CI with those of their family caregivers and reported more discrepancies in agreement about PADLs and IADLs: Older persons who had severe cognitive loss rated themselves as more independent than their caregivers.
TABLE 4--Multiple Regression of Depression Category on PADL, IADL and Social Functioning Summary Scores: Adjusted Mean Scores at 12 Months Postfracture(a)
NOTE: PADL = physical activities of daily living; IADL = instrumental activities of daily living.
All PADL, IADL, and social function items that made up summary scores were analyzed individually to examine whether particular types of activities were affected.
Participants who were persistently depressed had lower cognitive and prefracture PADL and social function than those who were not depressed (Table 6).
