Psychometric properties of the German version of the Fear of Falling Questionnaire-revised (FFQ-R) in a sample of older adults after hip or pelvic fracture.

BACKGROUND: Identifying patients with maladaptive fear of falling (FOF) is important in the rehabilitation phase after serious fall. The 6-item Fear of Falling Questionnaire-revised (FFQ-R) was seen as promising measurement instrument as it evaluates FOF in a broader way than the one-item-question and independent of physical activities. AIM: The purpose of the analysis was to evaluate the psychometric properties of the translated German FFQ-R. METHODS: Back-translation method was applied. Confirmatory factor analysis (CFA) with diagonally weighted least square estimation was used to verify the two-factor structure. Data were collected during inpatient rehabilitation from hip and pelvic fracture patients [age 84.3 ± 6.2, Mini-Mental State Examination (MMSE) scores > 23] participating in an RCT (N = 112) and a cross-sectional survey (N = 40). RESULTS: Internal consistency was 0.78 (Cronbach´s alpha). No floor or ceiling effects were found. Discriminatory power on item level was moderate to good (r = 0.43-0.65). CFA revealed a good model fit and confirmed the two-factor structure. The German FFQ-R was moderately correlated (r = 0.51) with the Short Falls Efficacy Scale-International (Short FES-I) used as a proxy measure for FOF. Missing rates up to 9% for specific items were because some individuals, independent of cognitive level or age, had problems to rate items with conditional statements on possible negative consequences of a fall. CONCLUSIONS: Results demonstrated moderate to good psychometric properties similar to the original English version in a comparable sample of fracture patients.

German version of the outcome expectations for exercise scale-2 : Psychometric properties in geriatric patients after hip or pelvic fractures with fear of falling.

OBJECTIVE: Physical exercise is associated with many health benefits. Especially for older adults it is challenging to achieve an appropriate adherence to exercise programs. The outcome expectations for exercise scale 2 (OEE-2) is a 13-item self-report questionnaire to assess negative and positive exercise outcome expectations in older adults. The aim of this study was to translate the OEE­2 into German and to assess the psychometric properties of this version. METHODS: The OEE­2 was translated from English into German including a forward and backward translation process. Psychometric properties were assessed in 115 patients with hip/pelvic fractures (76% female, mean age 82.5 years) and fear of falling during geriatric inpatient rehabilitation. RESULTS: Principal component analyses could confirm a two-factor solution (positive/negative OEE) that explained 58% of the total variance, with an overall internal reliability of α = 0.89. Cronbach's α for the 9­item positive OEE subscale was 0.89, for the 4­item negative OEE subscale 0.79. The two subscales were correlated with rs = 0.49. Correlations of the OEE total score were highest with the perceived ability to manage falls, prefracture leisure time activities and prior training history (rs = 0.35-0.41). CONCLUSION: These results revealed good internal reliability and construct validity of the German version of the OEE­2. The instrument is valid for measuring physical exercise outcome expectations in older, German-speaking patients with hip or pelvic fractures and fear of falling.

Multifactorial intervention for hip and pelvic fracture patients with mild to moderate cognitive impairment: study protocol of a dual-centre randomised controlled trial (OF-CARE).

BACKGROUND: A hip or pelvic fracture is a major fall-related injury which often causes a decline in mobility performance and physical activity. Over 40% of patients with hip fracture have cognitive impairment or dementia and poorer rehabilitation outcomes than those without cognitive impairment. In this subgroup, there is a lack of evidence on the best practices supporting recovery. The main aim of this study is to investigate the effects of a transitional care intervention after inpatient rehabilitation on physical activity and functional performance in this group of cognitively impaired patients. METHODS/DESIGN: This dual-centre, randomised controlled trial compares a multifactorial intervention with usual care as control condition. Two hundred and forty community-dwellers (≥ 65 years) with a hip or pelvic fracture and mild to moderate cognitive impairment (MMSE 17-26) are recruited at the end of inpatient rehabilitation. The four-month intervention consists of (a) an individually tailored, progressive home exercise program and physical activity promotion delivered by professional instructors and lay instructors (two home visits per week) and (b) a long-term care counselling approach addressing unmet care needs, pleasurable activities, and caregiver issues if needed. Primary outcome parameters are physical activity, measured as daily walking duration with an accelerometer-based activity monitor (activPAL™) over 72 h, and functional performance, assessed with Short Physical Performance Battery sum scores. Secondary outcome parameters are fear of falling, fall related self-efficacy, falls, quality of life, depression and activity of daily living. Data are collected at the end of rehabilitation, before the intervention at the patient's home (baseline), after four months (post-intervention), and seven months (follow-up). In addition to completer and intent-to-treat analyses of outcomes, economic data and incremental cost-effectiveness are analysed. DISCUSSION: Existing service models of volunteer services and legal counselling provided by care counsellors were considered when developing the intervention protocol. Therefore, it should be feasible to translate and deliver the intervention into real-world practice if it has been demonstrated to be effective.

Transition from inpatient rehabilitation to the home environment in cognitively impaired older persons after hip fracture.

OBJECTIVE: To investigate short-term changes in clinical characteristics in the transition period between geriatric inpatient rehabilitation and independent living at home in older patients with hip/pelvic fracture and cognitive impairment. DESIGN: Longitudinal observational study. SUBJECTS: A total of 127 multi-morbid, older patients with hip/pelvic fracture and cognitive impairment. METHODS: Physical performance, fall-related self-efficacy, fear of falling, depressive symptoms, quality of life, and pain were assessed before discharge from geriatric inpatient rehabilitation and at home. RESULTS: During the transition period (median 18.5 days; interquartile range 14-25 days), 25 participants dropped out due to admission to a nursing home (n = 11), withdrawal of consent (n = 8), death (n = 2), severe disease (n = 2), or other reasons (n = 2). Physical performance improved (p ≤ 0.001), while fall-related self-efficacy (p = 0.040) and fear of falling (p = 0.004) deteriorated. Depressive symptoms, quality of life, and pain did not change. Improvement in physical performance was associated with lower age, lower baseline physical performance, less baseline fear of falling, and living alone. CONCLUSION: While significant improvements in physical performance indicate a high potential for further enhancements in the majority of participants following inpatient rehabilitation, a considerable subgroup dropped out, partly indicating a negative trajectory in this vulnerable patient group. Sustained physical training or promotion of activity at home may further support rehabilitation in patients with hip/pelvic fracture and cognitive impairment.
