          Abstract

          Background

          Fear of falling and associated avoidance of activity are common among older people and may have negative consequences in terms of functional decline, quality of life and institutionalisation. We evaluated the effects of a cognitive behavioural group intervention to reduce fear of falling and associated avoidance of activity among older persons. This intervention showed favourable effects on fear of falling, avoidance of activity, daily activity, and several secondary outcomes. The aim of the present study is to assess the feasibility of this cognitive behavioural group intervention for participants and facilitators.

          Methods

          The intervention consisted of eight weekly group sessions lasting two hours each and a booster session after six months. Self-administered questionnaires, registration forms and interviews were used to collect data from participants (n = 168) and facilitators (n = 6) on the extent to which the intervention was performed according to protocol, participant attendance, participant adherence, and participants' and facilitators' opinion of the intervention. Quantitative data from the questionnaires and registration forms were analysed by means of descriptive statistics. Qualitative data were categorised based on matching contents of the answers.

          Results

          Facilitators reported no major protocol deviations. Twenty-six percent of the participants withdrew before the start of the programme. Of the persons who started the programme, 84% actually completed it. The participants reported their adherence as good, but facilitators had a less favourable opinion of this. The majority of participants still reported substantial benefits from the programme after six and twelve months of follow-up (71% and 61% respectively). Both participants and facilitators provided suggestions for improvement of the intervention.

          Conclusion

          Results of this study show that the current cognitive behavioural group intervention is feasible for both participants and facilitators and fits in well with regular care. Minor refinement of the intervention, however, is warranted to further improve intervention effectiveness and efficiency. Based on these positive findings, we recommend implementing a refined version of this effective and feasible intervention in regular care.

          Risk factors for falls among elderly persons living in the community.

          To study risk factors for falling, we conducted a one-year prospective investigation, using a sample of 336 persons at least 75 years of age who were living in the community. All subjects underwent detailed clinical evaluation, including standardized measures of mental status, strength, reflexes, balance, and gait; in addition, we inspected their homes for environmental hazards. Falls and their circumstances were identified during bimonthly telephone calls. During one year of follow-up, 108 subjects (32 percent) fell at least once; 24 percent of those who fell had serious injuries and 6 percent had fractures. Predisposing factors for falls were identified in linear-logistic models. The adjusted odds ratio for sedative use was 28.3; for cognitive impairment, 5.0; for disability of the lower extremities, 3.8; for palmomental reflex, 3.0; for abnormalities of balance and gait, 1.9; and for foot problems, 1.8; the lower bounds of the 95 percent confidence intervals were 1 or more for all variables. The risk of falling increased linearly with the number of risk factors, from 8 percent with none to 78 percent with four or more risk factors (P less than 0.0001). About 10 percent of the falls occurred during acute illness, 5 percent during hazardous activity, and 44 percent in the presence of environmental hazards. We conclude that falls among older persons living in the community are common and that a simple clinical assessment can identify the elderly persons who are at the greatest risk of falling.

            Falls efficacy as a measure of fear of falling.

            We developed the Falls Efficacy Scale (FES), an instrument to measure fear of falling, based on the operational definition of this fear as "low perceived self-efficacy at avoiding falls during essential, nonhazardous activities of daily living." The reliability and validity of the FES were assessed in two samples of community-living elderly persons. The FES showed good test-retest reliability (Pearson's correlation 0.71). Subjects who reported avoiding activities because of fear of falling had higher FES scores, representing lower self-efficacy or confidence, than subjects not reporting fear of falling. The independent predictors of FES score were usual walking pace (a measure of physical ability), anxiety, and depression. The FES appears to be a reliable and valid method for measuring fear of falling. This instrument may be useful in assessing the independent contribution of fear of falling to functional decline among elderly people.

              Fear of falling and fall-related efficacy in relationship to functioning among community-living elders.

              The relationships of fear of falling and fall-related efficacy with measures of basic and instrumental activities of daily living (ADL-IADL) and physical and social functioning were evaluated in a cohort of community-living elderly persons. Sociodemographic, medical, psychological, and physical performance (e.g., gait speed, timed hand function) measures were administered, during an in-home assessment, to a probability sample of 1,103 residents of New Haven, Connecticut, who were > or = 72 years of age. Falls and injuries in the past year, fear of falling, and responses to the Falls Efficacy Scale were also ascertained. The three dependent variables included a 10-item ADL-IADL scale, an 8-item social activity scale, and a scale of relative physical activity level. Among cohort members, 57% denied fear of falling whereas 24% acknowledged fear but denied effect on activity; 19% acknowledged avoiding activities because of fear of falling. Twenty-four percent of recent fallers vs 15% of nonfallers acknowledged this activity restriction (chi 2 = 13.1; p < .001). Mean fall-related efficacy score among the cohort was 84.9 (SD 20.5), 79.8 (SD 23.4), and 88.1 (SD 17.9) among fallers and nonfallers, respectively (p < or = .0001). Fall-related efficacy proved a potent independent correlate of ADL-IADL (partial correlation = .265, p < .001); physical (partial correlation = .234, p < .001); and social (partial correlation = .088, p < .01), functioning in multiple regression models after adjusting for sociodemographic, medical, psychological, and physical performance covariates as well as history of recent falls and injuries. Fear of falling was only marginally related (p = .05) with ADL-IADL functioning and was not associated with higher level physical or social functioning. The strong independent association between self-efficacy and function found in this study suggests that clinical programs in areas such as prevention, geriatric evaluation and management, and rehabilitation should attempt simultaneously to improve physical skills and confidence. Available knowledge of the factors influencing efficacy should guide the development of these efficacy-building programs.
