Falls Efficacy Scale-International: Exploring psychometric properties with adult day care users

Studies in the Falls Efficacy Scale-International for patients with cervical compressive myelopathy: Reliability, validity, and minimum clinically important difference

CONTEXT

Patients with cervical compressive myelopathy (CCM) often complain of body balance problems, such as fear of falling and bodily unsteadiness. However, no accepted patient-reported outcome measures (PROMs) for this symptomatology exist. The Falls Efficacy Scale-International (FES-I) is one of the most widely used PROMs for evaluating impaired body balance in various clinical fields.

OBJECTIVE

To examine reliability, validity, and minimum clinically important difference (MCID) of the FES-I for the evaluation of impaired body balance in patients with CCM.

METHODS

Patients who underwent surgery for CCM were retrospectively reviewed. The FES-I was administered preoperatively and at 1 year postoperatively. Further, cJOA-LE score (subscore for lower extremities in the Japanese Orthopaedic Association score for cervical myelopathy) and stabilometric data, obtained at the same time points of the FES-I administration, were analyzed. Reliability was examined through internal consistency with Cronbach's alpha. Convergent validity was studied using correlation analysis. The MCID was estimated using anchor- and distribution-based methods.

RESULTS

Overall, 151 patients were included for analysis. Cronbach's alpha coefficient was the acceptable value of 0.97 at both baseline and 1 year postoperatively. As for convergent validity, the FES-I had significant correlations with the cJOA-LE score and stabilometric parameters both at baseline and 1 year postoperatively. The MCID calculated using anchor- and distribution-based methods was 5.5 and 10, respectively.

CONCLUSION

FES-I is a reliable and valid PROM to evaluate body balance problems for the CCM population. The established thresholds of MCID can help clinicians recognize the clinical significance of changes in patient status.

Association between personality traits and concerns about falling among older patients: the mediating role of subjective age

Background

Older patients are at high risk of falling, and regular assessments of their concerns about falling (CaF) are often recommended. The present study aimed to investigate the association between CaF and personality traits among older patients as well as to elucidate the mediating role of subjective age.

Method

A cross-sectional study was conducted among 407 patients aged over 60 years in a tertiary hospital located in Chengdu, Sichuan Province, from March 2023 to May 2023. Predesigned electronic questionnaires were distributed to collect relevant data. Four different models (both crude and adjusted weighted linear regression models) were constructed based on the confounders. Confounders were gradually put into the models to control for bias and to examine the stability of the correlations. Bootstrap sampling was employed to examine the mediating role of subjective age.

Result

According to the fully adjusted model, neuroticism (β = 0.17, 95% CI: 0.02 to 0.31, p for trend = 0.02), extraversion (β = -0.07, 95% CI: -0.15 to 0.001, p for trend = 0.05), and subjective age (β = 2.02, 95% CI: 1.28 to 2.78, p for trend <0.001) were consistently correlated with CaF. Mediating analysis revealed that extraversion was negatively related with CaF both directly and indirectly, via subjective age [23.2% partial effect, bootstrap 95%CI: -0.024(-0.080, -0.000)]. Higher neuroticism was consistently related to older subjective age (β = 0.002, 95% CI: 0.001 to 0.004, p for trend = 0.006), while higher levels of conscientiousness, openness, and extraversion were consistently correlated with younger subjective age(β = -0.002, p for trend = 0.04; β = -0.003, p for trend = 0.003; β = -0.002, p for trend = 0.0, respectively).

Conclusion

Extraversion and neuroticism were significantly correlated with CaF. Moreover, subjective age partially mediated the relationship between extraversion and CaF. Furthermore, subjective age was found to be associated with both CaF and personality traits. These findings highlighted the important roles of personality traits and subjective age in assessments of CaF and in the development of strategies for preventing falls among older patients.

Adding Weight Shift Training to Weight Reduction Decreases the Risk of Falling in Obese Women: A Prospective Randomized Controlled Trial

OBJECTIVE

The aim of this study was to examine the effect of adding weight shift training to a weight loss program on the risk of falling, fear of falling, overall stability, anteroposterior stability, mediolateral stability, and isometric knee torque in young obese women.

DESIGN

A single-blinded, randomized controlled study was performed. Sixty women, 18 to 46 yrs old, were randomly assigned either to the study or the control group. The participants in the study group were given weight-shifting training plus a weight reduction program; the control group received only a weight-reduction program. The interventions were performed for 12 wks. At baseline and after 12 wks of training, the risk of falling, fear of falling, overall stability, anteroposterior stability, mediolateral stability, and isometric knee torque were all examined.

RESULTS

There were statistically significant differences in risk of falling, fear of falling, isometric knee torque, and overall, anteroposterior, and mediolateral stability indices, in favor of the study group, after 3 mos of training ( P < 0.001).

CONCLUSIONS

Weight shift training combined with weight reduction was more beneficial than weight reduction alone in decreasing the risk of falling and fear of falling and improving isometric knee torque and overall, anteroposterior, and mediolateral stability indices. It could be used for treating balance problems and weakness around the knee joint in obese women.

A systematic review and meta-analysis of the measurement properties of concerns-about-falling instruments in older people and people at increased risk of falls

BACKGROUND

The 16-item Falls Efficacy Scale International (FES-I) is widely used to assess concerns-about-falling. Variants include 7-item Short FES-I, 30-item Iconographical Falls Efficacy Scale (Icon FES) and 10-item short Icon FES. No comprehensive systematic review and meta-analysis has been conducted to synthesise evidence regarding the measurement properties of these tools.

OBJECTIVES

To conduct a systematic review and meta-analysis of the measurement properties of four FES-I variants.

METHODS

MEDLINE, Embase, CINAHL Plus, PsycINFO and Web of Science were searched systematically and articles were assessed for eligibility independently. The methodological quality of eligible studies was assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. The quality of measurement properties was assessed using COSMIN criteria for good measurement properties. Where possible, meta-analysis was conducted; otherwise, narrative synthesis was performed. Overall certainty of evidence was rated using a modified Grading of Recommendations, Assessment, Development and Evaluation system approach.

RESULTS

The review included 58 studies investigating measurement properties of the four instruments. There was high-quality evidence to support internal consistency, reliability and construct validity of all instruments. Moderate- to high-certainty evidence suggests one-factor structure of FES-I with two underlying dimensions, one-factor structure of Short FES-I and two-factor structure of Icon FES. There was high-certainty evidence to support the responsiveness of FES-I, with further research needed for the other instruments.

CONCLUSION

There is evidence for excellent measurement properties of all four instruments. We recommend the use of these tools with healthy older people and people at a greater risk of falls due to conditions that might affect mobility and balance.

Relationship between Associated Neuropsychological Factors and Fall Risk Factors in Community-Dwelling Elderly

This study examined whether neuropsychological factors could affect fall risk factors in the community-dwelling elderly via correlation analysis. A total of 393 older adults (76.69 ± 6.01) participated in this study. Cognitive function, depression, fall efficacy, balance confidence, balance, gait, and muscle strength were evaluated, and the correlation between psychological factors and fall risk factors was analyzed. Additionally, a multiple regression analysis was conducted to determine whether or not there was a significant effect between psychological factors and fall risk factors. Analysis showed that the psychological factors examined were all significantly correlated with the fall risk factors. A correlation analysis between cognitive function and fall risk factors showed that the correlation coefficient of the 6-Meter Walk Test was highest; for depression and fall risk factors, the correlation coefficient of gait speed was highest; for fall efficacy and fall risk factors, the correlation coefficient of the 6-Meter Walk Test was highest; and for confidence in balancing and fall risk factors, the correlation coefficient of the 6-Meter Walk Test was highest. This study suggests that psychological factors affect fall risk factors in the community-dwelling elderly, and a multifaceted approach that includes psychological factors would be helpful in providing interventions for falls.

Validation of the short falls efficacy scale-international for Taiwanese community-dwelling older adults: Associations with fall history, physical frailty, and quality of life

The FES-I is widely used to measure the fear of falling. However, studies linking the Chinese version of the FES-I to frailty and quality of life among older adults are still limited. Thus, this study examined the association of the full 16-item FES-I and the 7-item short FES-I with fall history, physical frailty, and quality of life among older Taiwanese adults. A total of 751 community-dwelling older adults in Taipei City participated in this study. Data analyses included logistic and linear regression models. The 16-item and the short FES-I were strongly correlated (Spearman rho = 0.963), and both scales are reliable. The 7-item FES-I was positively associated with fall history and physical frailty and negatively associated with the physical (b = -0.65, p < 0.001) and mental (b = -0.59, p < 0.001) components of health-related quality of life, independent of physical frailty. Thus, the short FES-I can be used to increase the feasibility of health screenings of older adults in Chinese-speaking contexts.

Sex Differences in Subsequent Falls and Falls Risk: A Prospective Cohort Study in Older Adults

BACKGROUND

Sex differences for subsequent falls and falls risk factors in community-dwelling older adults who have fallen are unknown. Our aim was to: (1) compare the number of falls between sexes, (2) identify modifiable falls risk factors, and (3) explore the interaction of sex on falls risk factors in older adults who fall.

METHODS

Four hundred sixty-two community dwellers seeking medical attention after an index fall were recruited from the Vancouver Falls Prevention Clinic and participated in this 12-month prospective cohort study. Ninety-six participants were part of a randomized controlled trial of exercise. Falls were tracked with monthly falls calendars. Demographics, falls risk measures, and the number of subsequent falls were compared between sexes. A principal component analysis (PCA) was employed to reduce the falls risk measures to a smaller set of factors. The PCA factors were used in negative binomial regression models to predict the number of subsequent falls. Age, exposure time (i.e., number of falls monitoring days), and prescribed exercise (yes/no) were used as covariates, and sex (male/female) and PCA factors were used as main effects. The interaction of sex by PCA factor was then included.

RESULTS

Males fell more over 12 months (males: 2.80 ± 6.86 falls; females: 1.25 ± 2.63 falls) than females, and poorer executive function predicted falls in males. Four PCA factors were defined - impaired cognition and mobility, low mood and self-efficacy, mobility resilience, and perceived poor health - each predicted the number of falls. The sex by mobility resilience interaction suggested that mobility resilience was less protective of falls in males.

CONCLUSION

Modifiable risk factors related to cognition, physical function, psychological wellbeing, and health status predicted subsequent falls. In males, better mobility was not as protective of falls compared with females. This may be due to males' poorer executive function, contributing to decreased judgement or slowed decision-making during mobility. These results may inform efficacious sex-specific falls prevention strategies.

An outpatient Tai Chi program: Effects on veterans' functional outcomes

PURPOSE

To evaluate the effectiveness of an evidence-based 12-week Tai Chi course designed to improve balance and physical function in a population of older veterans.

METHODS

Community dwelling veterans of all ages with gait and balance problems were invited to participate in the Tai Chi program. Participants completed the Berg Balance Scale (BBS), the Timed Up and Go (TUG) test, and the Falls Efficacy Scale-International (FES-I) at baseline and again at the end of the program. Descriptive statistics were used to summarize study participants' characteristics. The change from baseline to the end of the 12-week program was calculated for each of the three primary outcome variables (BBS, TUG, FES-I).

RESULTS

Twenty-two veterans, aged 58 years and above, with perceived gait and/or balance issues were enrolled in the program with completion by 11 veterans. Veterans who completed their final assessments showed the BBS, improved significantly (p = 0.004) from baseline to the 12-week assessment. The TUG scores improved by a median of 1.3 s (p = 0.022). There was not a significant change in the FES-I.

CONCLUSIONS

Preliminary findings provide evidence of the effectiveness of a 12-week Tai Chi program to improve functional outcomes for older veterans with mild to moderate gait and balance problems.

Sleep Quality, Anxiety, and Depression Are Associated with Fall Risk Factors in Older Women

Gait, dynamic balance, and functional mobility problems are well-known fall risk factors. Furthermore, sleep disturbances, anxiety, and depression are prevalent among older women. This study aimed to analyze the associations of sleep quality, anxiety, and depression with functional mobility, gait speed, and dynamic balance in community-dwelling postmenopausal women aged ≥ 60 years. A total of 271 women (69.18 ± 5.69 years) participated in this study. Functional mobility (Timed Up-and-Go Test), dynamic balance (3-meter tandem walk test), gait speed (OptoGait® optical detection system), sleep quality (Pittsburgh Sleep Quality Index), and anxiety and depression (Hospital Anxiety and Depression Scale) were assessed. Our results showed that poor sleep efficiency and the use of sleeping medication were related to decreased gait speed (R2 = 0.072). Poor functional mobility was linked to depression and the use of sleeping medication (R2 = 0.159). Additionally, increased symptoms of anxiety and depression were associated with worsened dynamic balance (R2 = 0.127). In conclusion, poorer sleep quality is associated with slower gait speed and reduced functional mobility, which is also related, along with impaired dynamic balance, to higher levels of anxiety and depression.

Impact of Intensive Blood Pressure Therapy on Concern about Falling: Longitudinal Results from the Systolic Blood Pressure Intervention Trial (SPRINT)

OBJECTIVES

Concern about falling is common among older hypertension patients and could impact decisions to intensify blood pressure therapy. Our aim was to determine whether intensive therapy targeting a systolic blood pressure (SBP) of 120 mm Hg is associated with greater changes in concern about falling when compared with standard therapy targeting an SBP of 140 mm Hg.

DESIGN

Subsample analysis of participants randomized to either intensive or standard therapy in the Systolic Blood Pressure Intervention Trial (SPRINT).

SETTING

Approximately 100 outpatient sites.

PARTICIPANTS

A total of 2313 enrollees in SPRINT; participants were all age 50 or older (mean = 69 y) and diagnosed with hypertension.

MEASUREMENTS

Concern about falling was described by the shortened version of the Falls Efficacy Scale International as measured at baseline, 6 months, 1 year, and annually thereafter.

RESULTS

Concern about falling showed a small but significant increase over time among all hypertension patients. No differences were noted, however, among those randomized to intensive vs standard therapy (P = .95). Among participants younger than 75 years, no increase in concern about falling over time was noted, but among participants aged 75 years and older, the mean falls self-efficacy score increased by .3 points per year (P < .0001). No differences were observed between the intensive and standard treatment groups when stratified by age (P = .55).

CONCLUSION

Intensive blood pressure therapy is not associated with increased concern about falling among older hypertension patients healthy enough to participate in SPRINT. J Am Geriatr Soc 68:614-618, 2020.

Psychometric Properties of the Czech Version of the Falls Efficacy Scale-International in Patients with Early-Stage Dementia

Introduction

A fear of falling marks an important psychological factor connected with a reduction in the life space of people with dementia. The Czech version of the Falls Efficacy Scale-International (FES-I) has not been validated in patients with early-stage dementia.

Methods

The tests were administered to 282 patients with early-stage dementia. The test battery included the following: the FES-I, the Short Physical Performance Battery, the Geriatric Depression Scale, the Bristol Activity Daily Living Scale, and the Quality of Life-Alzheimer's Disease Scale. Internal reliability (Cronbach's α and intraclass correlation [ICC]), Pearson's and Spearman's correlations, exploratory factor analysis, and a t test for independent samples were used for statistical analyses.

Results

The Czech version of the FES-I had excellent internal and test-retest reliability (Cronbach's α = 0.98, ICC = 0.90; 95′ CI 0.82–0.94). Factor analysis suggested 2 relevant factors. A significantly higher FES-I score was associated with patients with early-stage dementia who were older (p = 0.003) or female (p = 0.001), lived alone (p = 0.0001), spent >8 h a day alone (p = 0.032), used mobility aids (p < 0.0001), or had severe hearing (p = 0.004) or vision impairment (p < 0.0001) or a lower education (r = −0.16, p = 0.007).

Conclusion

The Czech version of the FES-I had very good reliability and validity and may be useful in future cross-cultural comparisons in research among patients with early-stage dementia.
