Assessment of the Concurrent Validity of the ICF Core Set to Classify the Physical Health of Community-Dwelling Older Adults in Relation to Self-Rated Health

Abstract

The number of older individuals has grown steadily worldwide. 1 However, this increased longevity does not necessarily mean a healthy life. 1 The older population is more analyze the compromised and problematic categories in the ICF, an impairment index was created for each component. The relationship between self-rated health and the impairment indexes was assessed using the multinomial logistic regression test adjusted for age, sex, schooling, and perception of income sufficiency. Results: A greater likelihood of poor or very poor self-rated health was found in older individuals with the highest impairment index in (b) (odds ratio [OR] = 1.18; P < .001); (s) (OR = 1.11; P ≤ .001); (d) capacity (OR = 1.09; P = .02); and (d) performance (OR = 1.08; p = 0.01). Conclusion:The results suggest that the ICF core set is a valid instrument to assess the physical health of older adults, since it is associated with self-rated health and shows potential for use in clinical practice and scientific research, with universal language regarding functionality and physical health in older adults.
