“…One such factor is fear of falling. Fear of falling is a low confidence in mobility tasks (Tinetti et al, 1990) that may lead to a debilitating anxiety regarding balance ability (Lachman et al, 1998). Fear of falling has now been established to be highly prevalent among the elderly, affecting almost 60% of community dwelling seniors (Brouwer et al, 2001).…”

DEDICATIONI dedicate this thesis to my Poppa, John Joseph Lacey. You have taught me the meaning of dignity.iii ABSTRACTThe effects of postural threat and the potential consequences of obstacle contact on the obstacle negotiation kinematics among younger and older adults were examined. Seventeen older (OA; 7 males, 10 females; mean age, 68.94 ± 4.85) and fifteen younger adults (YA; 5 males, 10 females; mean age, 22.53 ± 2.77) negotiated virtual and real obstacles while walking at a self-determined velocity along a 7.2m walkway under 4 different conditions of postural threat. Postural threat was manipulated by varying the width (0.60m versus 0.15m) and height (floor versus elevated (0.00m versus 0.60m)) of the walkway. Postural threat altered crossing kinematics for all subjects. Specifically, age-related differences emerged with increasing postural threat, however die changes observed among older adults were considerably different from those of younger adults. Additionally, there was an effect for the potential consequences of obstacle contact, however, no age-related differences emerged. These results revealed an effect for postural threat and obstacle characteristics on the negotiation strategies of younger and older adults. Both postural threat and obstacle characteristics elicit conservative crossing kinematics in younger and older adults. Specifically, these findings illustrate age-dependent differences in obstacle negotiation strategies and that postural threat affects older adults differently than younger adults whereas the potential consequences of obstacle contact affects younger and older adults equally. iv ACKNOWLEDGEMENTSWe did it! This thesis would not have been possible without die support of my family and friends. I would like to show my appreciation to everyone who encouraged and stood by me during the creation of this thesis.

“…This is notable because evidence shows older adults having difficulties using response formats with many options. 24,29 An inability to differentiate between adjacent response options leads to respondent bias arising from an increase in subjectivity. 30 Given the current knowledge of the ABC-scale and some of the unanswered questions concerning its applicability among aging individuals with a lower-limb amputation living in the community, the objectives of this study were to: 1) explore shortened response formats for use with the ABC-scale; 2) evaluate the unidimensionality of the scale; 3) evaluate the item difficulty; 4) evaluate the scale for redundancy and content gaps; and 5) evaluate the item standard error of measurement (SEM) and internal consistency reliability.…”

Objective-To explore shortened response formats for use with the Activities-specific Balance Confidence scale and then: 1) evaluate the unidimensionality of the scale; 2) evaluate the item difficulty; 3) evaluate the scale for redundancy and content gaps; and 4) evaluate the item standard error of measurement (SEM) and internal consistency reliability among aging individuals (≥50 years) with a lower-limb amputation living in the community.Design-Secondary analysis of cross-sectional survey and chart review data.Setting-Out-patient amputee clinics, Ontario, Canada.Participants-Four hundred forty eight community living adults, at least 50 years old (mean = 68 years), who have used a prosthesis for at least 6 months for a major unilateral lower limb amputation. Three hundred twenty five (72.5%) were men. Intervention-N/aMain Outcome Measure(s)-Activities-specific Balance Confidence Scale.Results-A 5-option response format outperformed 4-and 6-option formats. Factor analyses confirmed a unidimensional scale. The distance between response options is not the same for all items on the scale, evident by the Partial Credit Model (PCM) having a better fit to the data than the Rating Scale Model. Two items, however, did not fit the PCM within statistical reason. Revising the wording of the two items may resolve the misfit, and improve the construct validity Corresponding author: Dr. William C Miller, Department of Occupational Science and Occupational Therapy, University of British Columbia, T325-2211 Wesbrook Mall, Vancouver, BC V6T 2B5, Tel work: 604-714-4108, Fax: 604-714-4168, bcmiller@telus.net.

Overall, the difficulty of the scale's items is appropriate for use with aging individuals with lower-limb amputation, and is most reliable (Cronbach ∝ = 0.94) for use with individuals with moderately low balance confidence levels.Conclusions-The ABC-scale with a simplified 5-option response format is a valid and reliable measure of balance confidence for use with individuals aging with a lower limb amputation. KeywordsAging; amputation; self-efficacy; rehabilitation; psychometrics; postural balanceFalling and the consequences of falling are important health issues for older individuals with a lower limb amputation. In Canada, the prevalence of falling among community dwelling individuals with a lower-limb amputation is reported to be as high as 52%. 1 Further, the annual incidence of falling among older adults (≥65 years) living in the community is commonly reported to be around 30% to ...
