VALIDATION OF THE INTERNATIONAL 7-ITEM FALLS EFFICACY SCALE IN PORTUGUESE COMMUNITY-DWELLING OLDER ADULTSObjective to determine the psychometric properties of the international 7-item Falls Efficacy Scale.
Method a psychometric study. Convenience sample consisting of 170 older adults living in the Madeira Autonomous Region, Portugal. A two-part instrument was used (sociodemographic characterization and the Falls Efficacy Scale-International-Portugal). The starting point was the translation and transcultural adaptation already carried out for the Falls Efficacy Scale - International (16 items). Construct validity (factorial analysis and discriminant validity) and the reliability (Cronbach's α) of the 7-item scale were evaluated. Previous authorization was obtained from the Ethics Commission and from the people involved.
Results in the exploratory factorial analysis, the International 7-item Falls Efficacy Scale presents an explained variance of 65.8%. The Spearman's correlation between the score obtained based on the 7 items and the score obtained based on the 16 items is significant and very strong (r=0.987, p<0.0001). Internal consistency was 0.958.
Conclusion the validity and reliability study of the International 7-item Falls Efficacy Scale revealed that it is an adequate scale for the evaluation of the fear of falling in the community-dwelling older adults.
