Cross-cultural adaptation and validation of the PRISMA-7 scale for European Portuguese

Abstract

Background. Frailty is an age-associated biological syndrome and a predictor of multimorbidity outcomes, whose early recognition allows for the identification of those older patients at risk. The PRISMA-7 scale allows for the identification of frail older people. Objectives. To make a cross-cultural adaptation and validation of the PRISMA-7 to the European spoken Portuguese language. Material and methods. Cross-cultural adaptation by translation of the PRISMA-7 scale into European Portuguese, debriefing and back-translation to English. Application for intra-observer reliability assessment and validation by simultaneous and concurrent application of the Katz scale. Results. Cronbach's alpha coefficient was of 0.420 and 0.409 after a re-test. Spearman's Rank Order Correlation of 0.969 in the re-test operation in a sample of 64 older people (35 female). More than 3 affirmative answers were found for older people (p < 0.001), for a higher number of self-reported drugs taken, (p = 0.001), self-reported years of education (p = 0.001), higher values for those with less years of studies were found in the validation of the translated PRISMA-7 scale, in a purposive sample of 127 older people, 72 (56.7%) female. No differences were found between gender (p = 0.414) and for number of self-reported diseases (p = 0.258). A Spearman correlation of ρ = 0.477 (p < 0.001) between the total of the two scales was found. Discussion. This comprehensive tool enables health care providers to discuss and architect more effective and efficient measures for these patients' care, regardless of gender, socio-demographic factors, number of self-reported drugs taken and diseases. Conclusions. The PRISMA-7 scale is now recommended to identify frail older people in the Portuguese community.

Predictors of frailty in older people users of Primary Health Care

“…However, other studies carried out in the community report higher values (25)(26) . Compared to studies carried out in Portugal, the prevalence of frail older people in the work on screen was lower (11)(12) . Duarte's (13) results are the closest to those reported in this study, probably because he used the same adapted version of the FP.…”

“…Additionally, a systematic review of population studies (n=11 studies) showed that FS is prevalent and is associated with a decrease in the survival of older people (10) . In Portugal, data on the prevalence of FS in the community, in different studies, ranged between 34.5% and 36.5% (11)(12)(13) .…”

Multidimensional Frailty and Lifestyles of Community-Dwelling Older Portuguese Adults

“…Frailty is common among older adults. In Portugal, data concerning the prevalence of frailty among community-dwelling people, in different studies, ranged from 15.6% to 54.8%, varying according to the screening instrument used [ 3 , 4 , 5 , 6 ]. This condition deteriorates not only the functional and cognitive capacity of older adults [ 7 ], but also the quality of life of older adults themselves and their families, caregivers, and society, hence it represents a public health priority that requires an early intervention [ 2 ].…”
