To verify the psychometric properties of the Brazilian-Portuguese version of the Falls Behavioral (FaB-Brazil) Scale in Parkinson's disease (PD). Participants (n = 96) were assessed by disease-specific, self-report and functional mobility measures. Internal consistency of the FaB-Brazil scale was evaluated using Cronbach's alpha and inter-rater and test–retest reliability using intraclass correlation coefficients (ICC). The standard error of measurement (SEM), minimal detectable change (MDC), ceiling and floor effects, and convergent and discriminative validity were evaluated. Internal consistency was moderate (α = 0.77). Excellent inter-rater (ICC = 0.90; p < 0.001) and test–retest (ICC = 0.91; p < 0.001) reliability were found. The SEM was 0.20 and MDC was 0.38. Ceiling and floor effects were not found. Convergent validity was established by the positive correlations between the FaB-Brazil scale and age, modified Hoehn and Yahr, PD duration, Movement Disorders Society-Unified Parkinson's Disease Rating Scale, Motor Aspects of Experiences of Daily Living, Timed Up & Go and 8-item Parkinson's Disease Questionnaire, and negative correlations between the FaB-Brazil scale and community mobility, Schwab & England, and Activities-specific Balance Confidence scale. Females showed greater protective behaviors than males; recurrent fallers showed greater protective behaviors than non-recurrent fallers (p < 0.05). The FaB-Brazil scale is reliable and valid for assessing people with PD. Fall-related behaviors should be part of the fall risk assessment of community-dwelling people with Parkinson's disease. The Brazilian-Portuguese version of the Fall Behavioral (FaB-Brazil) Scale is reliable and valid for assessing everyday behaviors and actions related to falling in community-dwelling people with Parkinson's disease. The FaB-Brazil scale may be used to tailor individualized fall prevention programs. [ABSTRACT FROM AUTHOR]

To develop and cross-culturally adapt a Brazilian-Portuguese version of the Falls Behavioral Scale (FaB-Brazil) and to verify its psychometric properties. The translation and cross-cultural adaptation process of the scale followed standard guidelines. The FaB-Brazil scale was applied to 93 community-dwelling older people. Cronbach's alpha was calculated to evaluate internal consistency and the intraclass correlation coefficient (ICC) to evaluate interrater and test–retest reliability. The standard error of measurement (SEM), minimal detectable change (MDC), ceiling and floor effects, convergent and discriminative validity were evaluated. A significance level of.05 was set for statistical analyses. Internal consistency was moderate (α = 0.73). An excellent inter-rater (ICC = 0.93; p < 0.001) and a good test–retest (ICC = 0.79; p < 0.001) reliability were found. The SEM was 0.27 and MDC was 0.53. Neither ceiling nor floor effects were found. Convergent validity was established by the positive correlations between the FaB-Brazil scale, age, and functional mobility, and by the negative correlations between the FaB-Brazil scale and balance confidence, community mobility and EuroQol-5D (p < 0.05). No significant differences were found between males and females and between non-fallers and fallers. Our results offer evidence for the reliability and validity of the FaB-Brazil scale for community-dwelling older people. Fall-related behaviors should be part of the fall risk assessment of community-dwelling older people. The Brazilian-Portuguese version of the Falls Behavioral Scale (FaB-Brazil) is reliable and valid for assessing fall-related behaviors in community-dwelling older people. The FaB-Brazil scale may be used to raise awareness about potential fall hazards and to guide fall prevention programs. [ABSTRACT FROM AUTHOR]

Background: Predictors of falls in people with Parkinson's disease (PD) who have not previously fallen are yet to be identified. Objectives: We aimed to identify predictors of all falls and recurrent falls in people with PD who had not fallen in the previous year and to explore the timing of falls in a 12-month follow-up period. Methods: Participants withPD(n = 130) were assessed by disease-specific, self-report and balance measures. Falls were recorded prospectively for 12 months. Univariate and multivariate analyses were performed. Kaplan-Meier survival analysis was used to investigate time to falling. Results: Forty participants (31%) had≥1 fall during follow-up and 21 (16%) had≥2 falls. Disability, reduced balance confidence and greater concern about falling were associated with ≥1 fall in univariate analyses. Additionally, PD duration and severity, freezing of gait and impaired balance were associated with ≥2 falls (p < 0.05). Disability (Schwab and England scale, Odds Ratio [OR] = 0.56 per 10 points increase; 95% confidence interval [CI] 0.39–0.80; p = 0.002) was associated with ≥1 fall in the final multivariate model (area under the receiver operating characteristic curve [AUC] = 0.65; 95% CI 0.55–0.76; p = 0.005). Disability (Unified Parkinson's Disease Rating Scale activities of daily living, OR= 1.20; 95% CI 1.07–1.34; p = 0.001) and levodopa equivalent dose (OR = 1.11 per 100 mg increase; 95% CI 0.95–1.30; p = 0.19) were associated with ≥2 falls in the final multivariate model (AUC= 0.72; 95% CI 0.60–0.84; p = 0.001). Recurrent fallers experienced their first fall earlier than single fallers (p < 0.05). Conclusions: Self-reported disability was the strongest single predictor of all falls and recurrent falls.
