OBJECTIVE: To validate a novel assessment of inpatient physical activity. DESIGN:
Prospective cohort study for the evaluation of a novel questionnaire for physical
activity in geriatric inpatients. SETTING: German geriatric inpatient
rehabilitation unit. PARTICIPANTS: Patients (N=96; 67 [72%] women; median age,
81y) with a variety of main underlying diagnoses, including musculoskeletal
diseases, hip fracture, cardiovascular diseases, stroke, and others.
INTERVENTIONS: Not applicable. MAIN : Ceiling and floor effects
and administration time were measured. For criterion-related concurrent validity
(convergent and discriminative), the Physical Activity in Inpatient
Rehabilitation Assessment (PAIR) was administered in parallel to self-rated,
proxy-rated, and performance-based measures of physical function at admission.
Measurements were repeated at discharge and 4-month follow-up in the home
environment, including a standard physical activity questionnaire to determine
predictive validity. Spearman correlation coefficients were calculated to
describe associations between parameters. Sensitivity to change was estimated
using standardized response means (SRMs). RESULTS: Administration time of the
PAIR ranged from less than 1 to 4 minutes. Ceiling effects occurred mainly at
discharge (5%-14%), and floor effects (5%-11%), at admission. There were no
missing values. Associations between convergent and predictive validity measures
and functional measures (r=.43-.53, r=.49-.54, respectively) were clearly better
when cognition was intact. Discriminative validity expressed as effect sizes
ranged from .27 to 1.44. The SRM to describe sensitivity to change was .65 for
the total score. CONCLUSIONS: The PAIR is the first validated questionnaire to
assess physical activity in geriatric inpatients. It is practical and its
validity and sensitivity to change are similar to existing physical activity
questionnaires for community-dwelling older persons.
