Self-reported mobility and instrumental activities of daily living: test-retest reliability and criterion validity

To determine the test-retest reliability and criterion validity of self-reported function in mobility and instrumental activities of daily living (IADL) in older adults, a convenience sample of 70 subjects (72.9 ± 6.6 yr, 34 male) was split into able and disabled groups based on baseline assessment and into consistently able, consistently disabled, and inconsistent based on repeat assessments over 2 weeks. The criterion validities of the self-reported measures of mobility domain and IADL-physical subdomain were assessed with concurrent baseline measures of 4 mobility performances, and that of the self-reported measure of IADL-cognitive subdomain, with the Mini-Mental State Examination. Test-retest reliability was moderate for the mobility, IADL-physical, and IADL-cognitive subdomains (κ = .51-.66). Those who reported being able at baseline also performed better on physical- and cognitive-performance tests. Those with variable performance between test occasions tended to report inconsistently on repeat measures in mobility and IADL-cognitive, suggesting fluctuations in physical and cognitive performance.     

Self- vs proxy-reported mobility using the mobility assessment tool-short form in elderly preoperative patients

Background

Mobility is fundamental to maintenance of an independent lifestyle and can predict clinical outcomes after health events among older individuals. However, certain clinical situations do not accommodate physical or self-assessments. This investigation examines whether proxy-reported assessments of function using the Mobility Assessment Tool-short (MAT-sf) form is a reliable alternative.

Methods

Sixty-six older persons (≥ age 70) and their proxies were enrolled. Proxies rated patients’ mobility using the MAT-sf as did the patients.

Results

The mean age of patients was 78.4 yr. (±6.2); 44% were female and 86% were white. Spouses made up 55% of the proxies, while 39% were children/in-laws. The correlation coefficient between patient and proxy MAT-sf scores was 0.81 (p?<?0.01); a comparison of the slope of the regression line relating patient- and proxy-reported MAT-sf to a line of identity showed disagreement (p?<?0.01), with proxy reports underreporting patient responses by 8.3% in lower mobility patients. The intra-class correlation characterizing agreement between repeated proxy reports 0.81.

Conclusion

Proxy reports of mobility in older patients have good reliability. However, in patients with poor mobility, the proxies tend to report a lower mobility than the patients.

     

Comparison between static maximal force and handbrake pulling force

The measurement of maximum pulling force is important not only for specifying force limit of industrial workers but also for designing controls requiring high force. This paper presents a comparison between maximal static handbrake pulling force (FST) and force exerted during normal handbrake pulling task (FDY). These forces were measured for different handle locations and subject characteristics. Participants were asked to pull a handbrake on an adjustable car mock-up as they would do when parking their own car, then to exert a force as high as possible on the pulled handbrake. Hand pulling forces were measured using a six-axes force sensor. 5 fixed handbrake positions were tested as well as a neutral handbrake position defined by the subject. FST and FDY were significantly correlated. Both were found to be dependent on handbrake position, age and gender. As expected, women and older subjects exerted lower forces. FST was significantly higher than FDY. The ratio FmR (FDY divided by FST) was also analyzed. Women showed higher FmR than men meaning that the task required a higher amount of muscle capability for women. FmR was also influenced by handbrake location. These data will be useful for handbrake design.     

Age-related changes in musculoskeletal function,balance and mobility measures in men aged 30–80 years

Objectives.?This study aimed to establish age-related changes in musculoskeletal function, balance and mobility measures in men.

Design.?An observational, cross-sectional cohort study was undertaken.

Methods.?One hundred six healthy, community-ambulant men (30–80 years) participated in this study. Recruitment of a convenience sample continued until a minimum of 20 men represented each decade between 30 and 80 years. Demographics (age, height, weight), health and current activity level were recorded. Balance and mobility were measured using the timed up and go test, the step test, functional and lateral reach. Reaction time was determined from limits of stability test. Leg muscle strength was measured with a spring gauge (kg), and ankle flexibility was measured using goniometry.

Results.?Balance, mobility and most strength measures were reduced by the 60s while ankle flexibility declined by the 70s (p?<?0.01). Reaction times increased by the 60s (p?<?0.01).

Conclusion.?This study of men demonstrated reduced musculoskeletal function, balance and mobility generally by the 60s. These results provide health professionals with normal performance levels to use as therapeutic goals as well as identify musculoskeletal factors associated with reducing balance and mobility. Hence, these results inform clinicians and policy makers for the establishment of pre-emptive interventions to promote healthier ageing.     

The inter-rater reliability and validity of self-report of risk factors for cumulative trauma disorders within the hand therapist population - a pilot study

OBJECTIVES: This study examined the validity of hand therapists' self-report of cumulative trauma disorder (CTD) risk factors by comparing the self-report to observations performed by the raters. Inter-rater reliability was also analyzed between the raters who observed the hand therapists. STUDY DESIGN: Two raters simultaneously observed each hand therapist during a splinting task at a therapy facility. Following this task, the raters and the hand therapist independently completed an identical assessment tool. Thirteen therapists were observed and a total of six raters observed the therapists. Responses from two categories of the self-assessment, "posture" and "mechanical stress", were compared. Percentage of agreement was calculated by dividing the number of like responses by the total number of possible responses for each category. RESULTS: Overall inter-rater reliability was 72%, significantly above the accepted minimum standard of 60-70%, and validity was 39%, significantly below the accepted minimum. CONCLUSION: The high percentage of inter-rater reliability established consistency and accuracy among the raters in their observations. However, the low percentage of validity should prompt hand therapists to investigate the accuracy of a patient's self-report before relying on it for treatment.     

Who is on the rise in Austria: Wage mobility and mobility risk

In this paper we investigate earnings mobility in Austria from the angle of individual persons. Earnings mobility over time has two aspects: Positional changes and the volatility of earnings over time. Whereas the further is a positive outcome, more volatility as such can be seen as negative. We use Austrian data from tax authorities to find out how population characteristics are related to these two concepts of earnings mobility. Our main results concern initial positions: The higher up you are at the beginning, the more difficult is further positional advancement, moreover, in terms of volatility we see that those in the lowest quantiles of the earnings distribution face the highest volatility of earnings positions over time. *Rudolf Winter-Ebmer is also associated with CEPR, London and IZA, Bonn.     

Ethical indices of income mobility

Ethical indices of income mobility measure the change in welfare resulting from mobility. The concept of mobility we explore consists of a welfare comparison between the actual time path of the income distribution with a hypothetical time path obtained by supposing that starting from the actual first-period distribution, the remaining income receipts exhibit complete immobility.     

Effects of vibration exercise on muscle performance and mobility in an older population

This study was designed to investigate the effects of vibration on muscle performance and mobility in a healthy, untrained, older population. Forty-three participants (23 men, 20 women, 66-85 y old) performed tests of sit-to-stand (STS), 5- and 10-m fast walk, timed up-and-go test, stair mobility, and strength. Participants were randomly assigned to a vibration group, an exercise-withoutvibration group, or a control group. Training consisted of 3 sessions/wk for 2 mo. After training, the vibration and exercise groups showed improved STS (12.4%, 10.2%), 5-m fast walk (3.0%, 3.7%), and knee-extension strength (8.1%, 7.2%) compared with the control (p < 0.05). Even though vibration training improved lower limb strength, it did not appear to have a facilitatory effect on functional-performance tasks compared with the exercise-without-vibration group. Comparable mobility and performance changes between the experimental groups suggest that improvements are linked with greater knee-extension strength and largely attributed to the unloaded squats performed by both exercise groups.     

The Use of the Child Abuse Potential Inventory in the Assessment of Parents involved in Care Proceedings

Assessing for potential physical abuse is a fundamental task for those professionals undertaking assessments of parents involved in care proceedings. One tool developed to help assist in this endeavour is the Child Abuse Potential (CAP) Inventory (Milner, 1980 , 1986 ). The CAP Inventory provides an estimate of parental risk of child abuse and is one of the most widely used psychometric tools by psychologists in child protection settings. This review evaluates the psychometric properties of this measure and provides an overview of its potential uses, as well as its limitations. It concludes that there is evidence to support the validity and reliability of the CAP Inventory for use in care proceedings. Specifically, the review indicates that the CAP Inventory has good levels of reliability and validity (construct, content and concurrent). The only aspect of validity for which there is a lack of evidence is that of predictive validity and this is due to a dearth of prospective studies. Given the above, the practical, clinical and ethical implications for the use of the CAP Inventory in the assessment of parents involved in care proceedings are discussed.

Industrialization, class structure, and social mobility in postwar Japan

This study examines intergenerational class mobility in Japan using cross-national comparisons with Western nations and cross-temporal comparisons of five national surveys conducted in postwar Japan. Cross-national comparisons highlight the similarity in relative mobility pattern between Japan and Western nations and at the same time the Japanese distinctiveness in absolute mobility rates especially regarding the demographic character of the Japanese manual working class. The results of cross-temporal comparisons of mobility pattern report some systematic trends in total mobility, inflow and outflow rates, reflecting the Japanese experience of late but rapid industrialization. The pattern of association between class origin and class destination, however, was stable in postwar Japan. It is therefore the combination of distinctive absolute mobility rates and similar relative mobility rates that characterizes the Japanese mobility pattern in comparison with the Western experience. Furthermore, Japan's distinctive pattern of postwar social mobility is characterized by a combination of rapidly changing absolute mobility rates and comparatively stable relative mobility rates.     

Motives for and barriers to physical activity among older adults with mobility limitations

The purpose of this study was to investigate what older adults with severe, moderate, or no mobility limitation consider motives for and barriers to engaging in physical exercise. Community-dwelling adults (N=645) age 75-81 years completed a questionnaire about their motives for and barriers to physical exercise and answered interview questions on mobility limitation. Those with severely limited mobility more often reported poor health, fear and negative experiences, lack of company, and an unsuitable environment as barriers to exercise than did those with no mobility limitation. They also accentuated disease management as a motive for exercise, whereas those with no or moderate mobility limitation emphasized health promotion and positive experiences related to exercise. Information about differences in motives for and barriers to exercise among people with and without mobility limitation helps tailor support systems that support engagement in physical activity among older adults.     

Reliability and Validity of the IPAQ-L in a Sample of Hong Kong Urban Older Adults: Does Neighborhood of Residence Matter?

This study examined reliability and validity of the Chinese version of the International Physical Activity Questionnaire-Long Form (IPAQ-LC) in Chinese seniors, including moderating effects of neighborhood walkability and socioeconomic status (SES) on reliability and validity. The IPAQ-LC was interviewer-administered (n = 96), accelerometer and 7-day walk-diary data were collected (n = 94), and the IPAC-LC was readministered (N = 92). Acceptable reliability was found for all measures of physical activity (PA) overall and across different types of neighborhood. Participants from highly walkable neighborhoods were more reliable at estimating walking for transport. Participants from low-SES areas were less reliable at estimating leisure-time PA and sitting but more reliable at estimating transport-related walking. IPAQ-LC walking was significantly related to light- but not moderate-intensity accelerometry-based PA. It was moderately to strongly related to a 7-day diary of walking. The data imply slow-paced walking, probably due to age, climate, and terrain. The findings suggest that the IPAQ-LC's reliability and validity are acceptable in Chinese seniors.     

The changing relationship between university education and intergenerational social mobility

This paper examines the intergenerational occupational mobility patterns for five cohorts of male and female university graduates who received degrees between i960 and 1976. After 1964 there is a marked decline in the prospects of both males and females for upward intergenerational mobility. Males still experience more mobility than females in all time periods, although the sex difference appears to be diminishing over time. This pattern reflects worsened mobility prospects for males rather than any improvement for females. Regional comparisons in the 1976 national data identify differences in the distribution of father's occupational prestige across Canada and, therefore, different structural conditions by region for intergenerational occupational mobility.
This paper examines three issues in intergenerational social mobility as measured by occupational achievement. Using new and earlier published data on five cohorts of graduates, we examine the extent to which university education has declined over time as a route to upward intergenerational mobility. Changes in the labour market for graduates are identified as the major reasons for such declines. Second, we examine the extent to which sex differences in intergenerational mobility have diminished over time and the extent to which this is a consequence of worsening mobility prospects for males rather than improving prospects for females. Third, we examine some differences in intergenerational mobility patterns for the five economic regions of Canada.     

Female marital mobility within Northern Ireland and the Republic of Ireland: a log-linear analysis

A series of log-linear models predicting the exchange marital experiences of Irish wives are prevented for the Irish Republic. The best explanatory model is one in which the relationship between a husband's occupational status and that of his father-in-law remains homogeneous across age levels, Women show a marked propensity to marry husbands at a similar occupational status as that of their fathers and long-range upward or downward mobility across the manual/nonmanual divide is unlikely. This tendency towards endogamy is particularly pronounced within the two upper non-manual categories and the manual strata generally the same general model of homogeneous association holds for Northern Ireland across age levels and religious affiliation. In the North, however, more short-range mobility occurs, particularly between the two upper non-manual groups. Despite this the norm for both the Irish Republic and Northern Ireland is marital immobility rather than marital mobility with no evidence of a fundamental trend towards increased marital mobility. Furthermore. The mobility through marriage that did occur does not result in an overall net advantage for women.     

Assessing behavior in children aged 12–24 months using the Strengths and Difficulties Questionnaire

Behavioral and emotional problems in infants and toddlers are common, often persist and put children at risk of later mental health problems. Reliable, efficient, and sensitive tools are needed to identify young children who may benefit from further assessment and support. The Strengths and Difficulties Questionnaire (SDQ), offers a brief, convenient means of screening for early problems, however, it lacks psychometric validation in infants. The aim of this study was to assess the validity and reliability of the SDQ in children aged 12–24 months. Ninety-three participants, with children aged 12–24 months, completed the SDQ and Child Behavior Checklist (CBCL) online. Concurrent validity of the SDQ was assessed through comparison with the CBCL. The results demonstrated that key subscales of the SDQ and CBCL were significantly correlated (r range= −.19 to –.57). Key SDQ subscales showed moderate reliability (Cronbach's alpha range = .38–.79, mean inter-item correlation range = .06–.43). The SDQ shows promising reliability and validity as a measure for rating the behavior of 12–24-months-old children, particularly for externalizing symptoms. Further research is needed to assess its predictive utility.     

The effect of 6 months training on leg power, balance, and functional mobility of independently living adults over 70 years old

Where strength training has been used in conjunction with functional-task training in older people, not only have there been improvements in leg strength but also improved function has been measured (e.g., Skelton & McLaughlin, 1996). Many studies use participants from care homes rather than community dwellers. We investigated changes in leg power, balance, and functional mobility in community-dwelling sedentary men and women over 70 years of age (n = 6 for training group [TR]; n = 10 for control group [CN]). Progressive training took place over 24 weeks using seated and nonseated exercise. For TR, leg power increased 40%, from 108 +/- 40 to 141 +/- 53 W (p < .01); dynamic balance increased 48%, from 22.3 +/- 7.9 to 33.1 +/- 6.1 cm (p < .01; functional reach); and functional mobility increased 12%, from 7.46 +/- 1.32 to 6.54 +/- 1.41 s (p < .05; timed walk). CN showed no significant change. In conclusion, a community-based exercise program led to large improvements in leg-extensor power, dynamic balance, and functional mobility.     

Gender discourses in academic mobility

Despite increasing geographic mobility among academic staff, gendered patterns of involvement in academic mobility have largely escaped scrutiny. Positioned within literatures on internationalization, physical proximity, gender and parenthood in academic mobility and understandings of gender as a process enacted through both discursive and embodied practices, we use discourse analysis based on interviews with academics in New Zealand to examine differences in language that create differing realities with regards to gender and obligations of care in academic mobility decisions. The findings reveal how academic mobility is discursively formulated as ‘essential’ to successful academic careers, with the need for frequent travel justified despite advances in virtual communication technologies. Heteronormative discourses are shown to disrupt and fragment the opportunities female academics have to engage in academic mobility. However, we also uncover ways in which these discourses are resisted, wherein fathers articulate emotional strain associated with academic mobility. The article shows how discourse works to constitute the essentialization of academic mobility, and the uneven gendered practices associated with it, whilst also giving voice to gender inequities in academic mobility from the southern hemisphere.     

Accessibility of sports facilities for persons with reduced mobility and assessment of their motivation for practice

This study aims to create awareness, both within the scientific community and among providers of sports facilities, for individuals with impaired or reduced mobility, promoting the development of technical solutions that allow greater autonomy and social integration of people with disabilities. The purpose of this work is, on the one hand, to evaluate the accessibility of sports facilities for people with reduced mobility and, on the other hand, to investigate why this user group has such low rates of participation in sporting activities. Firstly, using the Portuguese norms and legislation transcribed from European Community directives, a check list was created comprising all the items that sports facilities should abide by in order to provide accessibility and safety to people with reduced mobility. Another questionnaire was designed aimed at this user group, with questions pertaining to their desire and ability to use sports facilities. This questionnaire was distributed in Portugal, in the greater metropolitan area of Porto, to users of Rehabilitation Centres and Physiotherapy Clinics. The results obtained from the check-list showed the compliances and non-compliances of the respective sports facilities, proving that many barriers preventing the participation of people with reduced mobility still exist. Twenty-four people with permanent impairment of the lower extremities (paraplegia) answered the questionnaire pertaining to the desire and ability to perform physical activity. Two individuals (8%) had sporting activities available to them in their area of residence and only five (21%) performed any physical activity. The main reason given for not taking part in any activity was the lack of adapted sports facilities. All the participants felt that taking part in sports is beneficial. The benefits stated were: general well-being and development of the psychomotor component (e.g. coordination, balance, body posture), of physical condition (e.g. strength, resistance, flexibility) and social integration and quality of life. Besides wellbeing, they also mentioned social interaction, a way of occupying their time and an escape from the routine as the main motives for which they would like to take up physical exercise.     

The Phone-FITT: a brief physical activity interview for older adults

The purpose of this study was to develop a brief physical activity interview for older adults (Phone-FITT) and evaluate its test-retest reliability and validity. Summary scores were derived for household, recreational, and total PA. Reliability was evaluated in a convenience sample from a fall-prevention study (N = 43, 79.4 +/- 2.9 years, 51% male), and validity, in a random sample of individuals in older adult exercise programs (N = 48, 77.4 +/- 4.7 years, 25% male). Mean time to complete the Phone-FITT was 10 min for participants sampled from exercise programs. Evaluation of test-retest reliability indicated substantial to almost perfect agreement for all scores, with intraclass correlation coefficients (95% confidence intervals) ranging from .74 (.58-.85) to .88 (.8-.94). For validity, Spearman's rho correlations of Phone-FITT scores with accelerometer counts ranged from .29 (.01-.53) to .57 (.34-.73). Correlations of Phone-FITT recreational scores with age and seconds to complete a self-paced step test ranged from -.29 (-.53 to -.01) to -.45 (-.68 to -.14). This study contributes preliminary evidence of the reliability and validity of the Phone-FITT.     

Education,immigration and occupational mobility: a short-term analysis

The author examines the relationship between education and occupational status for immigrants and natives in the United States by analyzing the short-term occupational mobility of selected members of the 1965-1970 immigrant cohort. The effects of race, ethnicity, age, and family and marital status on this relationship are considered. The relationship between short-term mobility and the emigration of the foreign-born from the United States is also studied (SUMMARY IN FRE, SPA)
