| pubmed-article:21834306 | pubmed:abstractText | Frailty can lead towards serious adverse consequences, such as disability. With regard to prevention valid screening instruments are needed to identify frail older people. The aim was to evaluate and compare the psychometric properties of three screening instruments: the Groningen Frailty Indicator (GFI), the Tilburg Frailty Indicator (TFI) and the Sherbrooke Postal Questionnaire (SPQ). For validation purposes the Groningen Activity Restriction Scale (GARS) was added. | lld:pubmed |
