    • <p>Arnadottir SA, Lundin-Olsson L, Gunnarsdottir ED, Fisher AG. Application of Rasch analysis to examine psychometric aspects of the Activities-Specific Balance Confidence Scale when used in a new cultural context. OBJECTIVE: To investigate by using Rasch analysis the psychometric properties of the Activities-Specific Balance Confidence (ABC) Scale when applied in a new Icelandic context. DESIGN: Cross-sectional, population-based, random selection from the Icelandic National Registry. SETTING: Community-based. PARTICIPANTS: Icelanders (N=183), 65 to 88 years old, and 48% women. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: ABC, an instrument used to evaluate how confident older people are in maintaining balance and remaining steady when moving through the environment. An Icelandic translation of the ABC (ABC-ICE) scale was evaluated by implementing Rasch rating scale analysis to transform ordinal ABC-ICE scores into interval measures and evaluating aspects of validity and reliability of the scale. RESULTS: Participants were not able to differentiate reliably between the 11 rating scale categories of the ABC-ICE. Additionally, 3 items failed to show acceptable goodness of fit to the ABC-ICE rating scale model. By collapsing categories and creating a new 5-category scale, only 1 item misfit. Removing that item resulted in a modified version of ABC-ICE with 5 categories and 15 items. Both item goodness-of-fit statistics and principal components analysis supported unidimensionality of the modified ABC-ICE. The ABC-ICE measures reliably separated the sample into at least 4 statistically distinct strata of balance confidence. Finally, the hierarchical order of item difficulties was consistent with theoretic expectations, and the items were reasonably well targeted to the balance confidence of the persons tested. CONCLUSIONS: Rasch analysis indicated a need to modify the ABC-ICE to improve its psychometric properties. Further studies are needed to determine if similar analyses of other versions of the ABC, including the original one, will yield similar results.</p>

  • Are rural older Icelanders less physically active than those living in urban areas? : a population-based study
  • 2009
  • Ingår i: Scandinavian Journal of Public Health. - 1403-4948 .- 1651-1905. ; 37:4, s. 409-417

    • <p>BACKGROUND: Older people in rural areas have been labelled as physically inactive on the basis of leisure-time physical activity research. However, more research is needed to understand the total physical activity pattern in older adults, considering all domains of physical activity, including leisure, work, and domestic life. AIMS: We hypothesised that: (a) total physical activity would be the same for older people in urban and rural areas; and (b) urban and rural residency, along with gender and age, would be associated with differences in domain-specific physical activities. METHODS: Cross-sectional data were collected in Icelandic rural and urban communities from June through to September 2004. Participants were randomly selected, community-dwelling, 65-88 years old, and comprised 68 rural (40% females) and 118 urban (53% females) adults. The Physical Activity Scale for the Elderly (PASE) was used to obtain a total physical activity score and subscores in leisure, during domestic life, and at work. RESULTS: The total PASE score was not associated with rural vs. urban residency, but males were, in total, more physically active than females, and the 65-74-year-olds were more active than the 75-88-year-olds. In the leisure domain, rural people had lower physical activity scores than urban people. Rural males were, however, most likely of all to be physically active in the work domain. In both urban and rural areas, the majority of the physical activity behaviour occurred in relation to housework, with the rural females receiving the highest scores. CONCLUSIONS: Older Icelanders in rural areas should not be labelled as less physically active than those who live in urban areas. Urban vs. rural living may, however, influence the physical activity patterns among older people, even within a fairly socioeconomically and culturally homogeneous country such as Iceland. This reinforces the need to pay closer attention to the living environment when studying and developing strategies to promote physical activity.</p>

  • Participation frequency and perceived participation restrictions at older age : applying the International Classification of Functioning, Disability and Health (ICF) framework
  • 2011
  • Ingår i: Disability and Rehabilitation. - Informa Healthcare. - 0963-8288 .- 1464-5165. ; 33:23-24, s. 2208-2216

    • <p>Purpose: To identify variables from different components of International Classification of Functioning, Disability and Health (ICF) associated with older people's participation frequency and perceived participation restrictions. Method: Participants (N = 186) were community-living, 65-88 years old and 52% men. The dependent variables, participation frequency (linear regression) and perceived participation restrictions (logistic regression), were measured using The Late-Life Function and Disability Instrument. Independent variables were selected from various ICF components. Results: Higher participation frequency was associated with living in urban rather than rural community (beta = 2.8, p &lt; 0.001), physically active lifestyle (beta = 4.6, p &lt; 0.001) and higher cognitive function (beta = 0.3, p = 0.009). Lower participation frequency was associated with being older (beta = -0.2, p = 0.002) and depressive symptoms (beta = -0.2, p = 0.029). Older adults living in urban areas, having more advanced lower extremities capacity, or that were employed had higher odds of less perceived participation restrictions (adjusted odds ratio [OR] = 5.5, p = 0.001; OR = 1.09, p &lt; 0.001; OR = 3.7, p = 0.011; respectively). In contrast, the odds of less perceived participation restriction decreased as depressive symptoms increased (OR = 0.8, p = 0.011). Conclusions: Our results highlight the importance of capturing and understanding both frequency and restriction aspects of older persons' participation. ICF may be a helpful reference to map factors associated with participation and to study further potentially modifiable influencing factors such as depressive symptoms and advanced lower extremity capacity.</p>
