Self-administered physical activity questionnaires for the elderly: a systematic review of measurement properties

Psychometric Validation of the German Version of the Rapid Assessment of Physical Activity (RAPA): A Secondary Analysis of Cross-Sectional Survey Data

Background and Aims

Regular physical activity holds numerous health benefits for older people, yet the majority of older people do not meet the World Health Organization's physical activity recommendations. Brief physical activity screening tools can support healthcare professionals in identifying patients who would benefit from physical activity promotion and counselling. The Rapid Assessment of Physical Activity (RAPA) questionnaire is a validated brief physical activity screening tool designed for clinical practice.

Methods

We conducted a psychometric validation of a new German translation of the RAPA by performing a secondary analysis of survey data from 234 former cardiac rehabilitation patients (mean [SD] age 69 ± 11 years, 23% female) in Austria. For psychometric validation, we used the following survey measures: the new German version of the RAPA, two customized questions about physical activity behavior, one customized question about perceived health self-management, and the German version of the EuroQol health-related quality of life questionnaire. We performed Spearman's correlations to assess the relationship between the German RAPA and the other measures (i.e., physical activity behavior, self-management of health and health-related quality of life).

Results

Aerobic physical activity level according to the RAPA correlated significantly with weekly frequency (Spearman's rho = 0.31, 95% CI [0.18, 0.43], p < .001) and volume of PA (rho = 0.34, 95% CI [0.21, 0.45], p < .001), as well as perceived health self-management and five out of six dimensions of the EuroQol questionnaire.

Conclusion

Our data demonstrate convergent validity and contribute to the psychometric validation of the new German version of the RAPA. These initial findings lend themselves to future dedicated psychometric validation studies of the German RAPA (against gold-standard physical activity questionnaires or direct physical activity measures) to further explore the potential of this tool for use in German-speaking geriatrics healthcare.

Relationship between physical activities and mental health in older people: a bibliometric analysis

Objective

To summarize the general situation and focal points of research on the physical activity and mental health of older people over the past 15 years and provide references for future research.

Methods

Literature published between January 1, 2009, and December 31, 2023, was retrieved from the Web of Science core database. A bibliometric visualization analysis of countries/regions, institutions, authors, keywords, and references was conducted using CiteSpace6.1.R6.

Results

A total of 4,329 articles were included, and the annual number of articles published over the past 15 years showed an upward trend. The articles were primarily from 65 countries/regions and 626 institutions. The most represented country and institution were the USA and the University of Pittsburgh, respectively. Among the authors identified, Schuch and Callow were the most influential. The research focuses on four areas: the psychological effects of physical activity in older people; physical activity intervention approaches to the mental health of older people; physical activity and mental health assessment questionnaires; and the impact of physical activity on multidimensional aging. Research frontiers involve emerging topics such as the assessment and intervention of mental health in older people and the relationship between their physical activity and cognitive function.

Conclusion

This study conducted a comprehensive, objective, and visual analysis of publications and revealed the status of relevant studies, trending topics, and trends concerning the physical activity and mental health of older people from 2009 to 2023. We hope that this work will help researchers identify new perspectives on potential collaborators, important topics, and research frontiers.

Home-based aerobic exercise feasibility in oxaliplatin-receiving newly-diagnosed cancer survivors

PURPOSE

Physical activity (PA) is beneficial but difficult to maintain during chemotherapy. This pilot RCT explored the feasibility of the MI-Walk intervention-an 8-week motivational enhancement therapy- and home-based brisk walking intervention-among gastrointestinal (GI) cancer survivors receiving chemotherapy.

METHODS

Sixty stage II-IV GI cancer survivors were recruited from 5 sites at their second infusion visit. Participants were randomized to receive PA education alone or the MI-Walk intervention: motivational enhancement therapy consisting of 3 motivational interviewing and self-efficacy-enhancing counseling sessions, a Fitbit Charge 2, exercise diaries, telephone follow-up, scripted motivational email messages, and optional weekly walking groups.

RESULTS

The enrollment and completion rates were 62% and 90%, respectively. The MI-Walk participants (n = 29; mean age = 56.79, SD = 11.72; 97% white; 79% male) reported a baseline moderate-vigorous PA duration of 250.93 (SD = 636.52) min/wk. The mean MI-Walk Intervention acceptability score was 50.32 (SD = 12.02) on a scale of 14-70. Mean Fitbit and counseling helpfulness scores on a 5-point scale were 3.67 (SD = 1.43) and 3.44 (SD = 1.36), respectively. Participants' Fitbit moderate-vigorous PA 8-week averages ranged from 0 to 716.88 min/wk; 64% of participants adhered to ≥127 min/wk. Several characteristics (e.g., age, comorbidity, PA level, employment status, BMI, education level, gender, symptoms) were associated with enrollment, attrition, and intervention acceptability and adherence (p < 0.05).

CONCLUSION

Enrollment and retention were adequate. The Fitbit and counseling were the most helpful. Acceptability and adherence varied based on participant characteristics; therefore, intervention tailoring and further research among cancer survivors less physically active at baseline and most in need of complex exercise intervention are needed.

Physical activity during COVID-19 in people with systemic sclerosis: A Scleroderma Patient-centred Intervention Network COVID-19 Cohort longitudinal study

Introduction/Objective

People with systemic sclerosis (SSc) face barriers to physical activity. Few studies have described physical activity in SSc, and none have explored physical activity longitudinally during COVID-19. We evaluated physical activity from April 2020 to March 2022 among people with SSc.

Methods

The Scleroderma Patient-centred Intervention Network (SPIN) COVID-19 Cohort was launched in April 2020 and included participants from the ongoing SPIN Cohort plus external enrolees. Participants completed measures bi-weekly through July 2020, then every 4 weeks afterwards (28 assessments). Physical activity was assessed via the self-reported International Physical Activity Questionnaire-Elderly. Analyses included estimated means with 95% confidence intervals for physical activity across assessments. Missing data were imputed for main analyses. Sensitivity analyses included evaluating only participants who completed >90% of items for >21 of 28 possible assessments ('completers') and stratified analyses by sex, age, country and SSc subtype.

Results

A total of 800 people with SSc enrolled. Mean age was 55.6 (standard deviation (SD) = 12.6) years. Physical activity significantly decreased from April 2020 to March 2021 (standardized mean difference (SMD) = -0.17, 95% confidence interval (CI) = -0.26 to -0.07) and was stable from March 2021 to March 2022 (SMD = -0.05, 95% CI = -0.15 to 0.05). Results were similar for completers and subgroups. The proportion of participants who met World Health Organization minimum physical activity recommendations of at least 150 min of moderate-to-vigorous activity per week ranged from 63% to 82% across assessments.

Conclusion

Physical activity decreased by a relatively small amount, on average, across the pandemic. Most participants met recommended physical activity levels.

The Chinese version of the general benefit finding scale (GBFS): Psychometric properties in a sample of college students

BACKGROUND

Benefit finding has become a central construct in the evolution of positive psychology and attracted attention in recent literature. This study aimed to translate and validate the General Benefit Finding Scale (GBFS) in Chinese college students.

METHODS

Forward- and back-translation of the GBFS was followed by the assessment of semantic equivalence and content validity. A sample of 589 college students was recruited in China to conduct reliability and validity analysis. The construct validity was assessed using exploratory (EFA) and confirmatory factor analysis (CFA). Concurrent validity was assessed using Pearson's correlation coefficients of the GBFS with the Perceived Stress Scale (PSS) and World Health Organization-Five Well-Being (WHO-5). Internal consistency and two-week test-retest reliability were also evaluated.

RESULTS

The content validity index for each item ranged from 0.83 to 1.00. EFA revealed a six-factor model, which exhibited acceptable goodness of fit in CFA (standardized root mean square residual = 0.031, root mean square error of approximation = 0.059, goodness-of-fit index = 0.860, comparative fit index = 0.904, Tucker-Lewis index = 0.890, chi-squared/degree of freedom = 2.07). The concurrent validity of the GBFS was supported by its statistically significant correlations with PSS (r = -0.271, p<0.001) and WHO-5 (r = 0.354, p<0.001). Moreover, the internal consistency for the overall scale was satisfactory, with Cronbach's α coefficient of 0.93 and McDonald's omega reliability of 0.94. The test-retest reliability was 0.82.

CONCLUSIONS

Although the Chinese version of GBFS was examined in a homogeneous convenience sample of college students, it provides a reliable and valid instrument for assessing benefit finding in the Chinese context.

Validity, reliability, and readability of single-item and short physical activity questionnaires for use in surveillance: A systematic review

BACKGROUND

Accurate and fast measurement of physical activity is important for surveillance. Even though many physical activity questionnaires (PAQ) are currently used in research, it is unclear which of them is the most reliable, valid, and easy to use. This systematic review aimed to identify existing brief PAQs, describe and compare their measurement properties, and assess their level of readability.

METHODS

We performed a systematic review based on the PRISMA statement. Literature searches were conducted in six scientific databases. Articles were included if they evaluated validity and/or reliability of brief (i.e., with a maximum of three questions) physical activity or exercise questionnaires intended for healthy adults. Due to the heterogeneity of studies, data were summarized narratively. The level of readability was calculated according to the Flesch-Kincaid formula.

RESULTS

In total, 35 articles published in English or Spanish were included, evaluating 32 distinct brief PAQs. The studies indicated moderate to good levels of reliability for the PAQs. However, the majority of results showed weak validity when validated against device-based measurements and demonstrated weak to moderate validity when validated against other PAQs. Most of the assessed PAQs met the criterion of being "short," allowing respondents to complete them in less than one minute either by themselves or with an interviewer. However, only 17 questionnaires had a readability level that indicates that the PAQ is easy to understand for the majority of the population.

CONCLUSIONS

This review identified a variety of brief PAQs, but most of them were evaluated in only a single study. Validity and reliability of short and long questionnaires are found to be at a comparable level, short PAQs can be recommended for use in surveillance systems. However, the methods used to assess measurement properties varied widely across studies, limiting the comparability between different PAQs and making it challenging to identify a single tool as the most suitable. None of the evaluated brief PAQs allowed for the measurement of whether a person fulfills current WHO physical activity guidelines. Future development or adaptation of PAQs should prioritize readability as an important factor to enhance their usability.

Simplified Chinese adaptation of the Yale Physical Activity Survey: reliability and validity measurement in mainland China elderly women

Objective

To verify the reliability and validity of the simplified Chinese version of the Yale Physical Activity Survey (YPAS) scale in the measurement of physical activity of elderly women in mainland China to provide a new standardized scale for evaluating the level of physical activity.

Methods

Twenty-one healthy elderly women completed all the research procedures. The participants completed the questions on the YPAS and wore an Omegawave Sport Technology®System diagnostic system that recorded maximum oxygen uptake and the adaptation index of the energy metabolism system. The reliability of the YPAS was evaluated based on the consistency of the two measurements (pre-test and post-test), and its validity was verified based on the relevant indicators in the Omegawave diagnostic system. Descriptive statistics, intraclass correlation coefficient and Pearson correlation analysis were used. The significance level was set at p < 0.05.

Results

In terms of reliability, the Pearson correlation coefficient and ICC of the total physical activity time of YPAS (r = 0.917, ICC = 0.897) was high. In terms of total calories, the Pearson correlation coefficient and ICC of the two test results was high (r = 0.958, ICC = 0.934). On the YPAS total index, the Pearson correlation coefficient and ICC of the two test was high (r = 0.930, ICC = 0.920). In terms of validity, there was a moderate correlation between the energy metabolism system adaptation index and the YPAS-total time (r = 0.472) and a moderate correlation with total calories (r = 0.472). There was a high correlation between the YPAS-total index and the maximum oxygen uptake (r = 0.782).

Conclusion

The simplified Chinese version of the YPAS can measure the level of physical activity and energy metabolism of elderly women in mainland China. It is a reliable tool for measuring the physical activity of the elderly.

Associations between socioeconomic status and physical activity among older adults: cross-sectional results from the OUTDOOR ACTIVE study

BACKGROUND

Regular physical activity (PA) is an important strategy for healthy ageing. Socioeconomic status was found to be a key determinant of PA, however, evidence on associations between socioeconomic status and PA among older adults is limited. The aim of this study was to contribute to research on the associations of socioeconomic status and PA among older adults by including self-reported and objectively measured PA data. Furthermore, we examined the self-reported PA data more closely by looking at the activities separately.

METHODS

Cross-sectional data of 1507 participants (52.5% female) of the OUTDOOR ACTIVE study between 65 and 75 years, residing in Bremen, Germany, were included in the analyses. Self-reported PA was assessed via questionnaire and comprised all organised and non-organised activities. For analyses, mean hours per week of total and moderate to vigorous PA, and mean metabolic equivalents per week were used. Objectively measured PA was assessed using accelerometers over seven consecutive days. Socioeconomic status was included as an additive social class index containing education, income, and occupation. To test for associations between PA and socioeconomic status, linear regressions were carried out.

RESULTS

Self-reported PA showed significant negative associations with socioeconomic status for both men and women. Objectively measured PA was positively associated with socioeconomic status, which was significant in men but not in women. When examining physical activities separately, time spent on housework, gardening, biking, and walking decreased with increasing socioeconomic status. Women in the second SES quintile and men in the third quintile reported the most, and women in the first quintile and men in the fifth quintile the least hours per week spent on exercise.

CONCLUSIONS

The results of this study contributed to the existing research gap on the associations of socioeconomic status and PA among older adults. Moreover, we provided information on both self-reported and objectively measured PA, and showed the discrepancies in the two methods' results. These findings can help to develop PA promotion interventions targeting specific socioeconomic status groups and to develop accurate, valid, and reliable self-reported and objective measurements of PA for older adults.

Questionnaires measuring movement behaviours in adults and older adults: Content description and measurement properties. A systematic review

Background

Sleep, sedentary behaviour and physical activity are constituent parts of a 24h period and there are several questionnaires to measure these movement behaviours, the objective was to systematically review the literature on content and measurement properties of self- and proxy-reported questionnaires measuring movement behaviours in adults and older adults.

Methods

The databases PubMed, CINAHL, PsycINFO and SPORTDiscus were systematically searched until April 2021. Articles were included if: the questionnaires were design for adults and older adults; the sample size for validity studies had at least 50 participants; at least, both validity and test-retest reliability results of questionnaire that were developed specifically to measure the amount of sleep, sedentary behaviour or physical activity, or their combination were reported; and articles had to be written in English, Spanish, French, Portuguese, German, Italian or Chinese.

Findings and conclusions

Data extraction, results, studies’ quality, and risk of bias were evaluated using the Consensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. Fifty-five articles were included in this review, describing 60 questionnaires. None of the questionnaires showed adequate criterion validity and adequate reliability, simultaneously; 68.3% showed adequate content validity. The risk of bias for criterion validity and reliability were very low in 72.2% and 23.6% of the studies, respectively. Existing questionnaires have insufficient measurement properties and frequent methodologic limitations, and none was developed considering the 24h movement behaviour paradigm. The lack of valid and reliable questionnaires assessing 24h movement behaviours in an integrated way, precludes accurate monitoring and surveillance systems of 24h movement behaviours.

Psychometric Properties of the Turkish Adaptation of the Yale Physical Activity Survey

This study aimed to examine the convergent validity and test–retest reliability of the Turkish version of the Yale Physical Activity Survey (YPAS-TR). Eighty-one volunteer older adults were included in the study. Test–retest reliability was evaluated using the intraclass correlation coefficient. Correlation coefficients between YPAS-TR and Physical Activity Scale for the Elderly (PASE), Short Form-36, and Short Physical Performance Battery were examined for convergent validity. Acceptable intraclass correlation coefficient values were reached for YPAS-TR energy expenditure, total physical activity time and summary, vigorous, leisurely walking, moving, standing, and sitting indices (intraclass correlation coefficient = .96–.99). There was a moderate correlation between energy expenditure and total physical activity time with PASE (leisure time activities), PASE (household activities), and PASE (total) (r = .478, r = .468, r = .570, r = .406, r = .490, r = .550, respectively, p < .001). Also, a weak correlation was found between summary and leisurely walking index with PASE (household activities), standing index with PASE (leisure time activities), and PASE (total) (r = .285, p = .010; r = .257, p = .021; r = .238, p = .033; r = .283, p = .010; respectively). The results of the study suggest that the YPAS-TR is a valid and reliable measurement tool that can be used to assess the physical activity patterns of Turkish older adults.

Age-Related Decline in Physical Activity Level in the Healthy Older Japanese Population

The Dietary Reference Intakes 2020 divided the older population into those aged 65-74 y and those over 75 y old. However, physical activity level in each age group was not specified. This study examined age-related differences in physical activity level among healthy Japanese older people, and the effect of lifestyles on these differences. In total, 70 people (22 men, 48 women) aged 65-85 y old participated in this study. Total energy expenditure was measured using the doubly labeled water method, and basal metabolic rate using expired gas concentration and volume. The Physical Activity Scale for the Elderly and a triaxial accelerometer were used to assess physical activities. Physical activity level was significantly higher among 65-74 y old (median 1.86) than those over 75 y old (1.76). However, the Physical Activity Scale for the Elderly did not show any significant differences between the age groups. The duration of physical activity with 3.0-5.9 metabolic equivalents was longer for both locomotive and household activities among 65-74 y old than those over 75 y old. Younger participants walked a median of 6,364 steps a day, compared with 4,419 steps for older people. The 65-74 y old participants involved in paid work or who habitually exercised, and those over 75 y old taking more than 40 min a day of moderate to vigorous physical activity, and walking more than the median level for their sex and age group had significantly higher physical activity levels.

Test-retest reliability of physical activity questionnaires in Parkinson's disease

BACKGROUND

People with Parkinson's disease are less physically active than controls. It is important to promote physical activity, which can be assessed using different methods. Subjective measures include physical activity questionnaires, which are easy and cheap to administer in clinical practice. Knowledge of the psychometric properties of physical activity questionnaires for people with Parkinson's disease is limited. The aim of this study was to evaluate the test-retest reliability of physical activity questionnaires in individuals with Parkinson's disease without cognitive impairment.

METHODS

Forty-nine individuals with Parkinson's disease without cognitive impairment participated in a test-retest reliability study. At two outpatient visits 8 days apart, the participants completed comprehensive questionnaires and single-item questions: International Physical Activity Questionnaire-Short Form (IPAQ-SF), Physical Activity Scale for the Elderly (PASE), Saltin-Grimby Physical Activity Level Scale (SGPALS) and Health on Equal Terms (HOET). Test-retest reliability was evaluated using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), limits of agreement, weighted kappa or the Svensson method.

RESULTS

Several of the physical activity questionnaires had relatively low test-retest reliability, including the comprehensive questionnaires (IPAQ-SF and PASE). Total physical activity according to IPAQ-SF had an ICC value of 0.46 (95% confidence interval [CI], 0.21-0.66) and SEM was 2891 MET-min/week. The PASE total score had an ICC value of 0.66 (95% CI, 0.46-0.79), whereas the SEM was 30 points. The single-item scales of SGPALS-past six months (SGPALS-6 m) and HOET question 1 (HOET-q1) with longer time frames (6 or 12 months, respectively) showed better results. Weighted kappa values were 0.64 (95% CI, 0.45-0.83) for SGPALS-6 m and 0.60 (95% CI, 0.39-0.80) for HOET-q1, whereas the single-item questions with a shorter recall period had kappa values < 0.40.

CONCLUSIONS

Single-item questions with a longer time frame (6 or 12 months) for physical activity were shown to be more reliable than multi-item questionnaires such as the IPAQ-SF and PASE in individuals with Parkinson's disease without cognitive impairments. There is a need to develop a core outcome set to measure physical activity in people with Parkinson's disease, and there might be a need to develop new physical activity questionnaires.

Pragmatic Evaluation of Older Adults' Physical Activity in Scale-Up Studies: Is the Single-Item Measure a Reasonable Option?

Convergent validity and responsiveness to change of the single-item physical activity measure were assessed in adults aged 60 years and older, at baseline (n = 205) and 6 months (n = 177) of a health promotion program, Choose to Move. Spearman correlations were used to examine associations between physical activity as measured by the single-item measure and the Community Health Activities Model Program for Seniors (CHAMPS) questionnaire at baseline and for 6-month change in all participants and for sex and age (60-74 years, and ≥75 years) subgroups. Effect size assessed responsiveness to change in physical activity for both tools. Baseline physical activity by the single-item measure correlated moderately with physical activity by the CHAMPS questionnaire in all participants and subgroups. Correlations were weaker for change in physical activity. Effect size for physical activity change was larger for the single-item measure than for the CHAMPS questionnaire. The single-item measure is a valid, pragmatic tool for use in intervention and scale-up studies with older adults.

Validity and Test-Retest Reliability of a Thai Stroke Physical Activity Questionnaire

BACKGROUND AND OBJECTIVES

This study evaluated the validity and reliability of the Stroke Physical Activity Questionnaire (SPAQ), a Thai self-report questionnaire for assessing physical activity (PA) in participants with chronic stroke.

METHODS

The validity of the SPAQ was tested by correlating PA data from the SPAQ with data obtained from a waist worn accelerometer which participants wore for seven days. The participants completed the SPAQ twice, one week apart and test-retest reliability was calculated using intraclass correlation coefficient.

RESULTS

Forty-one participants, at least 3 months post-stroke (24 men and 17 women) were enrolled. The average age was 55.3 years (SD 11.9). Correlation coefficients of 0.58 and 0.57 were found between SPAQ and the accelerometer data for moderate PA and moderate to vigorous PA (MVPA), respectively. There was no significant correlation between light PA determined from SPAQ and accelerometer. The intraclass correlation coefficients were 0.56, 0.91 and 0.90 for light, moderate PA and MVPA, respectively.

CONCLUSIONS

The validity of the SPAQ for moderate and MVPA was acceptable and the test-retest reliability of the SPAQ was excellent. This suggests the SPAQ is a useful tool for assessing moderate PA and MVPA among chronic stroke participants. However, it cannot be used to quantify light PA.

Evaluation of a Health-Management Course for Recently Settled Immigrants

This study aims to evaluate an intervention, consisting of nine weeks of health-management course, combined with social and working life orientation and language instruction for recently settled immigrants in Sweden. One hundred one participants in the intervention groups and 48 participants in the control group participated. The intervention consisted of a health management course combined with social and working life orientation and the control group participated in the regular local authority program for social and working life orientation. Measurement instruments were health-related quality of life (HRQoL) and registration of work rate. Several participants in the groups were in work, primarily in subsidized employment, after six months. Recently settled men were employed to a greater extent than the women, where poorer physical and mental health could be observed among women in this study. Participants in the intervention and the control groups had maintained HRQoL from pre-intervention to six months post-intervention. More studies investigating the participants experiences of the health-managing course but also more homogenous measurements in studies for recently settled immigrants are needed.

Mitochondria-DNA copy-number and incident venous thromboembolism among middle-aged women: a population-based cohort study

Venous thromboembolism (VTE) is the third most common cardiovascular disease. Low amount of mitochondrial DNA copy number (mtDNA-CN) has been associated with arterial cardiovascular disease (CVD) and reflects mitochondrial dysfunctions. However, whether mtDNA-CN is associated with VTE has not been determined. To examine the association between mtDNA-CN and incident VTE among middle-aged women. 6917 women aged 50-64 years, followed for 20 years in the Women's Health In the Lund Area (WHILA) study. DNA samples for mtDNA quantification were available from 2521 women. Quantification of mtDNA-CN was performed using a well-optimized droplet digital PCR method. After exclusions of women with anticoagulant treatment, women living in nursing homes, and women who were diagnosed with cancer, stroke, VTE, or coronary heart disease at baseline, a cohort of 2117 women remained for analysis. Cox regression was used to analyze the relationship between mtDNA-CN and time to VTE (hazard ratio = HR). In total, 87 women were diagnosed with VTE during follow-up, corresponding to an incidence rate of 2.8 per 1000 person-years. Neither crude nor adjusted HR for mtDNA-CN were significantly associated with incident VTE. A sensitivity analysis with inclusion of excluded women did not change the results. MtDNA-CN was not significantly associated with VTE. The present study suggests that mtDNA-CN, reflecting mitochondrial dysfunction, should not be considered a biomarker that plays a major role for developing VTE. However, due to limited study size we may not exclude minor associations.

The Maugeri daily activity profile: a tool to assess physical activity in patients with chronic obstructive pulmonary disease

Patients with chronic obstructive pulmonary disease (COPD) report reduced physical activity (PA). There are only few tools available to assess PA and sedentary behavior in these patients, and none of them aims to differentiate between sedentary and active patterns. The aim of the study was to evaluate an easy tool to profile daily activity time in a cohort of patients with COPD, compared to healthy subjects; the study was set at the Istituti Clinici Scientifici Maugeri (ICS), IRCCS of Tradate and Lumezzane, Italy, and at the Ente Ospedaliero Cantonale Novaggio, Switzerland (Italian Speaking). The populations were inpatients with COPD, healthy subjects. The items of the Maugeri Daily Activity (MaDA) profile were chosen based on literature, interviews with patients and health professionals. Time spent during sleep (ST), when awake (AT), active (ACT) or in sedentary behavior (SET) were recorded. Lung function tests, arterial blood gases, the modified Medical Research Council (mMRC), the six-minute walking distance test (6MWD), the COPD Assessment Test (CAT), and the body-mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index were also assessed in patients. Sixty patients with COPD and 60 healthy controls filled in the questionnaire. As compared to controls, patients showed longer AT and SET. Active time of patients was significantly correlated with mMRC, CAT, Bode Index and 6MWD, but not with demographics, anthropometrics or stages of disease. Using this tool, we found that patients with COPD spent longer time awake and in sedentary behavior. The MaDA may be useful to evaluate PA in patients with COPD.

Effect of mindfulness on physical activity in primary healthcare patients: a randomised controlled trial pilot study

Abstract

Increased physical activity can have health benefits among inactive individuals. In Sweden, the healthcare system uses physical activity on prescription (PAP) to motivate patients to increase their physical activity level. Mindfulness may further heighten the internal motivation to engage in physical activity. However, previous research has not demonstrated clear evidence of such an association.

Aim

Examine the feasibility of the study design as a preparation for a full-scale study, and examine the differences, between three interventions, in change over time in physical activity levels and in related variables.

Method

Comparison between three different interventions in an ordinary primary health care setting: PAP, mindfulness, and a combination of PAP and mindfulness. Physical activity was measured with self-report and ACTi Graph GT1X activity monitor. Statistical analysis was performed with a mixed-effect model to account for repeated observations and estimate differences both within groups and between groups at 3- and 6-months follow-up.

Results

Between September 2016 and December 2018, a total of 88 participants were randomised into three groups. The total dropout rate was 20.4%, the attendance rate to the mindfulness courses (52% > 6 times) and the web-based mindfulness training (8% > 800 min) was low according to the stated feasibility criteria. Eleven participants were excluded from analysis due to low activity monitor wear time. Neither the activity monitor data nor self-reported physical activity showed any significant differences between the groups.

Conclusion

The study design needs adjustment for the mindfulness intervention design before a fully scaled study can be conducted. A combination of PAP and mindfulness may increase physical activity and self-rated health more than PAP or mindfulness alone.

Current Evidence of Measurement Properties of Physical Activity Questionnaires for Older Adults: An Updated Systematic Review

BACKGROUND

Questionnaires provide valuable information about physical activity (PA) behaviors in older adults. Until now, no firm recommendations for the most qualified questionnaires for older adults have been provided.

OBJECTIVES

This review is an update of a previous systematic review, published in 2010, and aims to summarize, appraise and compare the measurement properties of all available self-administered questionnaires assessing PA in older adults.

METHODS

We included the articles evaluated in the previous review and conducted a new search in PubMed, Embase, and SPORTDiscus from September 2008 to December 2019, using the following inclusion criteria (1) the purpose of the study was to evaluate at least one measurement property (reliability, measurement error, hypothesis testing for construct validity, responsiveness) of a self-administered questionnaire; (2) the questionnaire intended to measure PA; (3) the questionnaire covered at least one domain of PA; (4) the study was performed in the general, healthy population of older adults; (5) the mean age of the study population was > 55 years; and (6) the article was published in English. Based on the Quality Assessment of Physical Activity Questionnaires (QAPAQ) checklist, we evaluated the quality and results of the studies. The content validity of all included questionnaires was also evaluated using the reviewers' rating. The quality of the body of evidence was evaluated for the overall construct of each questionnaire (e.g., total PA), moderate-to-vigorous physical activity (MVPA) and walking using a modified Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

In total, 56 articles on 40 different questionnaires (14 from the previous review and 26 from the update) were included. Reliability was assessed for 22, measurement error for four and hypotheses testing for construct validity for 38 different questionnaires. Evidence for responsiveness was available for one questionnaire. For many questionnaires, only one measurement property was assessed in only a single study. Sufficient content validity was considered for 22 questionnaires. All questionnaires displayed large measurement errors. Only versions of two questionnaires showed both sufficient reliability and hypotheses testing for construct validity, namely the Physical Activity Scale for the Elderly (PASE; English version, Turkish version) for the assessment of total PA, and the Physical Activity and Sedentary Behavior Questionnaire (PASB-Q; English version) for the assessment of MVPA. The quality of evidence for these results ranged from very low to high.

CONCLUSIONS

Until more high-quality evidence is available, we recommend the PASE for measuring total PA and the PASB-Q for measuring MVPA in older adults. However, they are not equally qualified among different languages. Future studies on the most promising questionnaires should cover all relevant measurement properties. We recommend using and improving existing PA questionnaires-instead of developing new ones-and considering the strengths and weaknesses of each PA measurement instrument for a particular purpose.

Actividad física y calidad de vida relacionada con la salud en una comunidad académica

Objetivo. Explorar las diferencias entre los niveles de actividad física (AF) ‒ligero, moderado y vigoroso‒, en función a la Calidad de Vida Relacionada con la Salud (CvRS). Método. 269 participantes (M = 25.3, DE = 1.5) entre estudiantes, docentes y administrativos de una comunidad académica de Pereira, Colombia. La AF se evaluó con el International Physical Activity Questionnaire (IPAQ) y la CvRS con el Cuestionario de Salud SF-36. Resultados. Quienes reportaron tener un nivel de AF moderado mostraron significativamente mejor vitalidad, salud mental y salud en general (p < 0.05). Mientras que aquellos con nivel de AF vigoroso promediaron más alto en salud general. Los niveles de AF moderado y vigoroso, en comparación con el ligero, presentaron mayor puntaje en la salud general y mental (p < 0.05). Conclusión. Este estudio aportó evidencia a favor de la hipótesis del vínculo entre AF y CvRS; además, reveló que aquellos con niveles de AF moderado y vigoroso presentan mejor CvRS en dimensiones de función social, vitalidad y salud general y mental. Futuros estudios deberían enfocarse en diferenciar los niveles de AF que mejor favorecen la CvRS, principalmente, en población escolar.

Measuring the association of objective and perceived neighborhood environment with physical activity in older adults: challenges and implications from a systematic review

BACKGROUND

A supportive environment is a key factor in addressing the issue of health among older adults. There is already sufficient evidence that objective and self-reported measures of the neighborhood environment should be taken into account as crucial components of active aging, as they have been shown to influence physical activity; particularly in people aged 60+. Thus, both could inform policies and practices that promote successful aging in place. An increasing number of studies meanwhile consider these exposures in analyzing their impact on physical activity in the elderly. However, there is a wide variety of definitions, measurements and methodological approaches, which complicates the process of obtaining comparable estimates of the effects and pooled results. The aim of this review was to identify and summarize these differences in order to emphasize methodological implications for future reviews and meta analyzes in this field and, thus, to create a sound basis for synthesized evidence.

METHODS

A systematic literature search across eight databases was conducted to identify peer-reviewed articles examining the association of objective and perceived measures of the neighborhood environment and objectively measured or self-reported physical activity in adults aged ≥ 60 years. Two authors independently screened the articles according to predefined eligibility criteria, extracted data, and assessed study quality. A qualitative synthesis of the findings is provided.

RESULTS

Of the 2967 records retrieved, 35 studies met the inclusion criteria. Five categories of methodological approaches, numerous measurement instruments to assess the neighborhood environment and physical activity, as well as several clusters of definitions of neighborhood, were identified.

CONCLUSIONS

The strength of evidence of the associations of specific categories of environmental attributes with physical activity varies across measurement types of the outcome and exposures as well as the physical activity domain observed and the operationalization of neighborhood. The latter being of great importance for the targeted age group. In the light of this, future reviews should consider these variations and stratify their summaries according to the different approaches, measures and definitions. Further, underlying mechanisms should be explored.

Cross-cultural modifications and measurement properties of the CHAMPS questionnaire among Chinese older adults

Background/objective

The Community Health Activities Model Program for Seniors questionnaires (CHAMPS-Q) is one of the most extensively used instruments in assessing physical activity among older adults. However, no study had translated the CHAMPS-Q into Chinese, and no evaluations were made on the psychometric properties of the CHAMPS-Q among the Chinese population. Considering cultural differences in perceptions of language, cultural context and living habits, this study was of necessary to 1) translate and cross-culturally adapt the original CHAMPS-Q, and 2) examine the test-retest reliability and construct/predictive validity of the Chinese version of the CHAMPS-Q.

Methods

The English CHAMPS-Q was first translated into Chinese, synthesized, back-translated, and revised by an expert committee according to the pre-test results. The Chinese CHAMPS-Q was then assessed in a cross-sectional study consisting of 101 apparently healthy older adults. Test-retest reliability test was conducted with 7 days apart. The construct validity of the Chinese CHAMPS-Q was tested against accelerometer data, and the predictive validity was assessed against physical fitness as measured by the Senior Fitness Test.

Results

The Chinese CHAMPS-Q has moderate to excellent test-retest reliability (ICC = 0.72-.96, p < .05). Energy expenditure and duration in PA significantly correlated with all accelerometry outcomes (ρ = 0.22-.31, p < .05). All the outcomes from the CHAMPS-Q showed significant correlations with upper body muscle strength (ρ = 0.22-.34, p < .05).

Conclusion

The Chinese CHAMPS-Q has excellent test-retest reliability and acceptable construct and predictive validity in assessing the physical activity of Chinese older adults.

•

Cultural differences exist in physical activity habits between western and oriental older adults.

•

Cultural adaptions are necessary for the popularization of physical activity measurements.

•

Not only frequency and duration but also energy expenditures have significant meaning to physical activity evaluation.

•

The Chinese CHAMPS-Q is a reliable and valid instrument for assessing the physical activity of older adults.

Assessing physical activity and function in patients with chronic kidney disease: a narrative review

Physical activity potentially improves health outcomes in patients with chronic kidney disease (CKD) and recipients of kidney transplants. Although studies have demonstrated the beneficial effects of physical activity and exercise for primary and secondary prevention of non-communicable diseases, evidence for kidney patients is limited. To enlarge this evidence, valid assessment of physical activity and exercise is essential. Furthermore, CKD is associated with a decline in physical function, which may result in severe disabilities and dependencies. Assessment of physical function may help clinicians to monitor disease progression and frailty in patients receiving dialysis. The attention on physical function and physical activity has grown and new devices have been developed and (commercially) launched on the market. Therefore the aims of this review were to summarize different measures of physical function and physical activity, provide an update on measurement instruments and discuss options for easy-to-use measurement instruments for day-to-day use by CKD patients. This review demonstrates that large variation exists in the different strategies to assess physical function and activity in clinical practice and research settings. To choose the best available method, accuracy, content, preferable outcome, necessary expertise, resources and time are important issues to consider.

Physical activity in patients with cancer: self-report versus accelerometer assessments

PURPOSE

The level of daily physical activity in patients with cancer is frequently assessed by questionnaires, such as the Physical Activity Scale for the Elderly (PASE). Objective assessments, with for example accelerometers, may be a good alternative. The aim of this study was to investigate the agreement between the PASE questionnaire and accelerometer-assessed physical activity in a large group of patients with different types of cancer.

METHODS

Baseline accelerometer and PASE questionnaire data of 403 participants from the REACT (Resistance and Endurance Exercise After Chemotherapy, n = 227), the EXIST (Exercise Intervention After Stem-Cell Transplantation, n = 74), and NET-QUBIC (NEtherlands QUality of Life And Biomedical Cohort Studies In Cancer, n = 102) studies were available for the current analyses. Physical activity was assessed by the PASE questionnaire (total score) and accelerometers (total minutes per day > 100 counts). Linear mixed models regression analysis was used to assess the agreement between the PASE questionnaire and accelerometer-assessed physical activity.

RESULTS

The mean (SD) PASE score was 95.9 (75.1) points and mean (SD) time in physical activity measured with the accelerometer was 256.6 (78.8) min per day. The agreement between the PASE score and the accelerometer data was significant, but poor (standardized regression coefficient (B) = 0.36, 95%CI = 0.27; 0.44, p < 0.01).

CONCLUSION

Agreement between the PASE questionnaire and accelerometer-assessed physical activity was poor. The poor agreement indicates that they measure different physical activity constructs and cannot be used interchangeably to assess the level of daily physical activity in patients with cancer.

Device-measured sedentary behavior and physical activity in older adults differ by demographic and health-related factors

Background

Our aim was to describe and explore older adults' device-measured sedentary behavior and physical activity (PA) pattern by sex, age, education, marital status, body mass index, and physical function; and to assess agreement regarding fulfillment of PA recommendations, i.e. 150 min/week of moderate-to-vigorous intensity PA (MVPA), between device-measured and self-reported PA.

Method

We included 656 older adults (64% women), aged 66, 81-87 or ≥ 90 years from a Swedish population-based cohort study. The activPAL3 accelerometer provided information on sedentary behavior (sedentary time, sedentary bouts, sit-to-stand transitions) and PA. Stepping ≥100 steps/min was considered MVPA; standing and stepping < 100 steps/min were considered light-intensity PA (LPA). Self-reported PA was compared with min/week in MVPA and steps/day.

Results

On average, 60% of wear time was spent sedentary, 36% in LPA, and 4% in MVPA. Relative to men, women, had significantly (p < 0.05) more sit-to-stand transitions, spent 33 min/day less sedentary and 27 min/day more in LPA, and were more likely to report meeting PA recommendations, but showed no difference in steps/day, MVPA, or sedentary bout duration. Older age was associated with more sedentary time, lower MVPA and fewer steps/day. The prevalence of meeting PA recommendations was 59% device-measured and 88% by self-report with limited agreement between methods (Cohen's Kappa = 0.21, Spearman's rho = 0.28). Age differences were much more pronounced with objective measures than by self-report.

Conclusions

We found significant sex differences in sedentary behavior and time in LPA in older adults, but not in MVPA, in contrast to previous findings. Sedentary time increased with age, with small differences in accumulation pattern. MVPA time was lower with older age, obesity, and poor physical function. A majority of the participants > 80 years did not meet the PA recommendations. Given the strong relationships between sedentary behavior, PA and health in older adults, programs are needed to address these behaviors. Agreement between device-measured and self-reported fulfillment of PA recommendations was limited. Device-based measurement adds value to PA studies, providing richer and different data than self-report.

Do we have to reduce the recall period? Validity of a daily physical activity questionnaire (PAQ24) in young active adults

Background

Combining the strengths of physical activity (PA) diaries and questionnaires may be needed to improve the unsatisfying measurement quality of existing PA questionnaires. This study investigated the construct validity of a short PA questionnaire (Physical Activity Questionnaire for 24 h [PAQ24]) with a recall period of one day.

Methods

In this cross-sectional study, participants completed the PAQ24 on seven consecutive days while wearing an accelerometer (GENEActiv). Thereafter, the Global Physical Activity Questionnaire (GPAQ) was completed. Spearman correlation coefficients and Bland-Altman analysis were used to assess construct validity.

Results

Overall, 50 active adults (11 women, mean age = 25.1 ± 2.5) participated. Relative agreements between Total PA of PAQ24 and accelerometer were 0.37 ≤ ρ ≤ 0.72 for each day with satisfying agreement on five out of seven days. Weekly relative agreement for Total PA was moderate (ρ = 0.44). Relative agreements between PAQ24 and GPAQ were ρ = 0.43 for Total PA. Daily and weekly absolute agreements were poor indicated by wide limits of agreement.

Conclusions

In contrast to weekly Total PA, the majority of daily results of the PAQ24 showed satisfying construct validity. A short recall period may improve the measurement quality of PA questionnaires, but measurement errors and the costs of multiple administrations must be considered in future studies.

Effect of Acute Physical Exercise on Executive Functions and Emotional Recognition: Analysis of Moderate to High Intensity in Young Adults

Physical exercise (PE) is associated with cognitive changes and brain function. However, it is required to clarify the effect of PE in different intensities, population groups conditions and the EF duration over different cognitive domains. Besides, no studies are known to have evaluated the contextual emotional recognition. Therefore, we studied the effect of acute PE of moderate intensities up to higher ones to the executive functions and the contextual emotional recognition. The participants were evaluated and classified in two experiments according to the IPAQ short form self-report and control measures. In both experiments, the groups were randomized, controlled, and exposed to one session of indoor cycling through intervals of high measure intensity (75–85% HRmax). Experiment 1 comprised young adults who were physically active (PA) and healthy, apparently (n = 54, M_age = 20.7, SD = 2.5). Experiment 2 involved young adults who were physically inactive (IP) and healthy, apparently (n = 36, M_age = 21.6, SD = 1.8). The duration was the only factor that varied: 45 min for PA and 30 min for PI. The executive functions were evaluated by the Stroop, TMT A/B, and verbal fluency, and the emotional recognition through a task that includes body and facial emotions in context, simultaneously. The analysis of factorial mixed ANOVA showed effects on the right choices of the indoor cycling groups in the PA, and the time response in PI. Also, other effects were observed in the controlled groups. TMT-A/B measures showed changes in the pre-test–post-test measures for both experiments. Verbal fluency performance favored the control group in both experiments. Meanwhile, the emotional recognition showed an effect of the PE in error-reduction and enhanced the scores in the right choices of body emotions. These results suggest that the EF with intensities favored cognitive processes such as inhibitory control and emotional recognition in context. We took into account the importance of high-complexity tasks design that avoid a ceiling effect. This study is the first on reporting a positive effect of PE over the emotional contextual recognition. Important clinical and educational implications are presented implications which highlight the modulatory role of EF with moderate to high intensities.

The Physical Activity Questionnaire for the Elderly (PAQE): A Polish Adaptation

The aim of the study is to assess the reliability and validity of the Polish adaptation of the Physical Activity Questionnaire for the Elderly (PAQE-PL). One hundred and four older adults (75 women and 29 men) aged 65 to 89 (mean 72.2 ± 5.7 years) participated in the study. The test–retest procedure was used to evaluate the reliability of the PAQE-PL. Validity was assessed by comparing the results of the PAQE-PL with the measurements from an accelerometer (ActiGraph wGT3X+) and two questionnaires: the Polish version of the Community Healthy Activities Model Program for Seniors (CHAMPS-PL) and the Polish version of the Yale Physical Activity Survey (YPAS-PL). All test–retest interclass correlation coefficients (ICCs) were significant (ranged from 0.64 to 0.92). The long-term stability showed significant ICCs (ranged from 0.38 to 0.87) for all participants. In regard to validity, the obtained correlation coefficients were relatively low but statistically significant for all participants between the PAQE-PL scores and energy expenditure (r ranging from 0.25 to 0.26) measured by the accelerometer. The PAQE-PL correlated with almost all CHAMPS-PL indices, YPAS-PL energy expenditure, and total physical activity time. The results suggest that the adaptation of the PAQE-PL is an acceptable tool to estimate the physical activity level among older adults in the Polish population. We recommend the cautious and well-thought-out use of the PAQE-PL with a population of older women.

Self-Report Tools for Assessing Physical Activity in Community-Living Older Adults with Multiple Chronic Conditions: A Systematic Review of Psychometric Properties and Feasibility

Identifier l'outil d'autodéclaration de l'activité physique (AP) le plus adapté pour l'évaluation de l'AP chez les personnes âgées vivant dans la communauté qui sont atteintes de multiples maladies chroniques (MMC). L'AP peut avoir une influence positive sur la santé physique et psychologique de cette population. Bien qu'il existe des outils d'auto-évaluation de l'AP, les propriétés psychométriques et la faisabilité de l'utilisation de ces outils chez les personnes âgées avec MMC sont peu connues. Une revue systématique des études publiées entre 2000 et 2018 portant sur les propriétés psychométriques et la faisabilité de 18 outils d'auto-évaluation élaborés pour les personnes âgées vivant en communauté (≥ 65 ans) a été réalisée en vue de déterminer leur pertinence pour les personnes âgées atteintes de MMC. L'évaluation des données disponibles sur les propriétés psychométriques et la faisabilité des 18 outils d'auto-évaluation de l'activité physique a permis d'établir que l'Échelle d'évaluation de l'activité physique chez les personnes âgées (Physical Activity Assessment Scale for the Elderly; PASE) est l'outil d'auto-évaluation le plus adapté, qui devrait être recommandé pour la population de personnes âgées avec MMC.

The purpose of this study was to identify the self-report physical activity (PA) tool best suited for assessment of PA in community-dwelling older adults with multiple chronic conditions (MCC). PA can positively influence physical and psychological health in this population. Although self-report PA tools exist, little is known about the psychometric properties and feasibility of using these tools in older adults with MCC. A systematic literature review from 2000 to 2018 was conducted of studies reporting on the psychometric properties and feasibility of 18 self-report PA tools for community-dwelling older adults (≥ 65 years) to determine the suitability of these tools for use in older adults with MCC. Based on an assessment of the available evidence for the psychometric properties and feasibility of 18 different self-report PA tools, the Physical Activity Assessment Scale for the Elderly (PASE) is recommended as the best-suited self-report PA tool for older adults with MCC.

Meeting international aerobic physical activity guidelines is associated with enhanced cardiovagal baroreflex sensitivity in healthy older adults

PURPOSE

Cardiovagal baroreflex sensitivity (cvBRS) reflects the efficiency of modulating heart rate in response to changes in systolic blood pressure. International guidelines recommend that older adults achieve at least 150 min of moderate-vigorous physical activity per week. We tested the hypothesis that older adults who achieve these guidelines will exhibit greater cardiovagal baroreflex sensitivity versus those who do not.

METHODS

A cross-sectional comparison of older adults who did (active, 66 ± 5 years, 251 ± 79 min/week; n = 19) and who did not (inactive, 68 ± 7 years, 89 ± 32 min/week; n = 17) meet the activity guidelines. Beat-by-beat R-R intervals (electrocardiography) and systolic blood pressure (finger photoplethysmography) were recorded. Spontaneous cardiovagal baroreflex sensitivity was assessed using the sequence technique from 10 min of resting supine data. Cardiovagal baroreflex function was also measured during early phase II and phase IV of the Valsalva maneuver. Peak oxygen uptake was determined during maximal cycle ergometry. Moderate-vigorous intensity physical activity and time spent sedentary were assessed over 5 days using the PiezoRx and activPAL, respectively.

RESULTS

Groups had similar peak oxygen uptake (active 25 ± 9 vs. inactive 22 ± 6 ml/kg/min; p = 0.218) and sedentary time (active 529 ± 60 vs. inactive 568 ± 88 min/day; p = 0.130). However, the active group had greater (all, p < 0.019) cvBRS at rest (9.1 ± 2.7 vs. 5.0 ± 1.9 ms/mmHg), during phase II (8.2 ± 3.8 vs. 5.4 ± 2.1 ms/mmHg), and during phase IV (9.9 ± 3.8 vs. 5.6 ± 1.6 ms/mmHg). In the pooled sample, moderate-vigorous physical activity was positively correlated (all, p < 0.015) with spontaneous (R = 0.427), phase II (R = 0.447), and phase IV cvBRS (R = 0.629).

CONCLUSIONS

Independent of aerobic fitness and sedentary time, meeting activity guidelines was associated with superior cardiovagal baroreflex sensitivity at rest and during the Valsalva maneuver in older adults.

Development of the Korean Global Physical Activity Questionnaire: reliability and validity study

The goal of this study was to develop a Korean version of the Global Physical Activity Questionnaire (K-GPAQ) and to examine its reliability and validity. The English version of the GPAQ was translated to the Korean language (K-GPAQ) via forward-backward translation. Reliability of the K-GPAQ was evaluated using a one-week interval test-retest method with 115 individuals. Criterion-related validity of the K-GPAQ was examined with 199 participants using accelerometers. Cohen's kappa and Spearman's correlation coefficients were used to measure test-retest reliability and validity, respectively. A Bland-Altman analysis was used to assess agreement between physical activity (PA) levels measured via K-GPAQ and the accelerometer. Coefficients for the reliability of the K-GPAQ showed moderate agreement for recreational PA and slight agreement for work-related PA (Cohen's kappa: 0.60-0.67 for recreational PA and 0.30-0.38 for work-related PA and Spearman's rho: 0.27-0.47 for work-related PA and 0.53-0.70 for recreational PA). Criterion validity of the total amount of PA, as measured by the K-GPAQ and the accelerometer, showed a weak but significant correlation (r = 0.34, p < 0.01). The K-GPAQ is a reliable and valid questionnaire to measure PA although K-GPAQ overestimated PA levels.

Development and Preliminary Validation of a Stroke Physical Activity Questionnaire

Objective

The aim of the current study was to develop and then to determine preliminary validity of a physical activity questionnaire specifically designed for ambulatory, chronic stroke patients.

Methods

This cross-sectional study recruited 92 chronic stroke patients. In Phase I, the SPAQ was developed and its content validity index (CVI) determined. In Phase II, we examined (1) the concurrent validity of SPAQ vs. the International Physical Activity Questionnaire-Short Form (IPAQ-SF); (2) the convergent validity of SPAQ vs. the Functional Ambulation Category (FAC), vs. the six-minute walk test (6-MWT), vs. the timed up and go test (TUGT), vs. the Motricity Index, vs. the National Institutes of Health Stroke Scale (NIHSS), and vs. the Modified Rankin Scale (MRS); and (3) the discriminant validity of the SPAQ vs. the Montreal Cognitive Assessment (MoCA). The concurrent validity and convergent and divergent validity were analysed using Spearman's rank correlation coefficient. The agreement between the SPAQ and IPAQ-SF was assessed using the Kappa statistic.

Results

The SPAQ has 12 items in 3 main components which covers low (7 items), moderate (3 items), and vigorous (2 items) physical activity. The SPAQ had a CVI of 0.93. Spearman's correlation coefficient (r_s) for SPAQ vs. IPAQ-SF was 0.53 (p < 0.001). The SPAQ yielded substantial agreement with the IPAQ-SF (Kappa = 0.65). For convergent validity, the SPAQ had a moderate correlation with the 6-MWT, MI, NIHSS, FAC, TUGT, and MRS (p < 0.05). For discriminant validity, the SPAQ was not correlated with the MoCA (r_s = 0.061, p = 0.68).

Conclusion

The SPAQ can be used to practically assess physical activity in chronic stroke patients, and it has acceptable psychometric properties which are comparable to other standard physical activity questionnaires. Future work should determine the validity of the SPAQ using an objective device such as an accelerometer.

Polish Adaptation of the Yale Physical Activity Survey: Measurement Properties

The aim of this study was to assess the measurement properties of a Polish adaptation of the Yale Physical Activity Survey (YPAS-PL). The Polish cultural adaptation of the YPAS was administered to a group of 104 people aged 65 to 89 years (mean age 72 ± 5). To assess the reliability of the YPAS-PL, a test-retest procedure was applied. Validity was assessed by comparing the results of the YPAS-PL with accelerometery (ActiGraph wGT3X+). The indicators based on the YPAS-PL activities checklist were characterized by high repeatability and had better reliability values than the YPAS-PL activity dimension indices (energy expenditure interclass correlation coefficient (ICC) = 0.81, total time physical activity ICC = 0.86). We noted a significant positive relationship between energy expenditure measured by an accelerometer and the YPAS-PL (r = 0.23). We can conclude that the YPAS-PL is an adequate tool for assessing energy expenditure related to physical activity in a Polish population of older adults. We also recommend the cautious and well thought-out use of the YPAS-PL activity dimension indices (summary, vigorous, leisurely walking, moving, standing, and sitting indexes).

Activities of daily living in older community-dwelling persons: a systematic review of psychometric properties of instruments

BACKGROUND

Activities of daily living (ADL) are often used as predictors of health and function in older persons. This systematic review is part of a series initiated by the European Network for Action on Ageing and Physical Activity (EUNAAPA).

AIM

To assess psychometric properties of ADL instruments for use in older populations.

METHODS

Electronic databases (Medline, EMBASE, AMED, Psycinfo, CINAHL) were searched, using MeSH terms and relevant keywords. Studies, published in English, were included if they evaluated one or more psychometric properties of ADL instruments in community-dwelling older persons aged 60 years and older. Combination scales with IADL were excluded. This systematic review adhered to a pre-specified protocol regarding reliability, validity, and responsiveness.

RESULTS

In total, 140 articles describing more than 50 different ADL instruments were included. Ten instruments which were applied in minimally three different articles of good quality (clear descriptions and adequate design according to the protocol), were evaluated for reliability, validity and responsiveness; each received a summary score. The four instruments with the highest scores were the Functional Autonomy Measurement System (SMAF), 5-items Katz list (although content and wording are often inconsistent across studies), Functional Independence and Difficulty Scale (FIDS) and the Barthel Index.

DISCUSSION

Critical reflection is essential to avoid unnecessary modifications and use of instruments that have not been documented to be valid or reliable.

CONCLUSION

Based on this systematic review, we recommend the SMAF, 5-item Katz, FIDS and Barthel index as ADL measures for research and care practice in older populations.

Use of Physical Activity Questionnaires in People With Dementia: A Scoping Review

Physical activity questionnaires are an important means to assess habitual physical activity. It remains unclear what questionnaires are used and whether they are appropriate for people with dementia who have impaired information recall but are also often largely sedentary. This scoping review aimed to identify and quantify the use of physical activity questionnaires within a dementia population. Eighteen studies met the inclusion criteria for this review. The majority of studies used questionnaires that were validated for use within an older adult population (e.g., Modified Baecke Questionnaire for the Elderly), though none had specifically been validated for use in people with dementia. Interestingly, just over half of the studies (N = 10, 55.6%) adapted the questionnaires from the original validated version by allowing a proxy to provide input to the responses. Future research needs to robustly validate the use of proxy-report measures of physical activity in people with dementia.

Validity and Reliability of the Polish Adaptation of the CHAMPS Physical Activity Questionnaire

The aim of the study was to investigate the reliability and construct validity of the Polish adaptation of the Community Health Activities Model Program for Seniors (CHAMPS) physical activity questionnaire among the elderly. The sample included 104 volunteers, 75 women (age = 71.0 ± 5.0 years) and 29 men (age = 75.1 ± 6.6 years). To assess the reliability of the Polish version of the CHAMPS physical activity questionnaire, measurements were conducted by one-week test-retest. The construct validity of the CHAMPS physical activity questionnaire was evaluated using accelerometers. Criterion validation was verified by self-reported measurements (health self-assessment, life satisfaction, and wellbeing) and body composition analysis. Intraclass correlation coefficients of the one-week test-retest ranged from 0.79 to 0.85. Significant Pearson's correlations were found between caloric expenditure measured by accelerometer and CHAMPS caloric expenditure in all listed physical activities (r = 0.33) and caloric expenditure in at least moderate intensity physical activities (r = 0.37) of the CHAMPS physical activity questionnaire. Moderate and greater intensity physical activities of CHAMPS measure were significantly related to total bone mass, health self-assessment, life satisfaction as a whole, and personal wellbeing (r ranged from 0.26 to 0.34). The findings of the study allow us to conclude that the Polish version of the CHAMPS physical activity questionnaire has acceptable reliability and validity to assess physical activity of older adults.

Physical Activity Questionnaires for Pregnancy: A Systematic Review of Measurement Properties

Background

In order to assess physical activity (PA) during pregnancy, it is important to choose the instrument with the best measurement properties.

Objectives

To systematically summarize, appraise, and compare the measurement properties of all self-administered questionnaires assessing PA in pregnancy.

Methods

We searched PubMed, Embase, and SPORTDiscus with the following inclusion criteria: (i) the study reported at least one measurement property (reliability, criterion validity, construct validity, responsiveness) of a self-administered questionnaire; (ii) the questionnaire intended to measure PA; (iii) the questionnaire was evaluated in healthy pregnant women; and (iv) the study was published in English. We evaluated results, quality of individual studies, and quality of evidence using a standardized checklist (Quality Assessment of Physical Activity Questionnaires [QAPAQ]) and the GRADE (Grading of Recommendation, Assessment, Development, and Evaluation) approach.

Results

Seventeen articles, reporting 18 studies of 11 different PA questionnaires (17 versions), were included. Most questionnaire versions showed insufficient measurement properties. Only the French and Turkish versions of the Pregnancy Physical Activity Questionnaire (PPAQ) showed both sufficient reliability and construct validity. However, all versions of the PPAQ pooled together showed insufficient construct validity. The quality of individual studies was usually high for reliability but varied considerably for construct validity. Overall, the quality of evidence was very low to moderate.

Conclusions

We recommend the PPAQ to assess PA in pregnancy, although the pooled results revealed insufficient construct validity. The lack of appropriate standards in data collection and processing criteria for objective devices in measuring PA during pregnancy attenuates the quality of evidence. Therefore, research on the validity of comparison instruments in pregnancy followed by consensus on validation reference criteria and standards of PA measurement is needed.

Comparison of psychometric properties between recall methods of interview-based physical activity questionnaires: a systematic review

BACKGROUND

This systematic review examined the methodological quality of studies and assessed the psychometric qualities of interview-administered Past-week and Usual-week Physical Activity Questionnaires (PAQs). Pubmed and Embase were used to retrieve data sources.

METHODS

The studies were selected using the following eligibility criteria: 1) psychometric properties of PAQs were assessed in adults; 2) the PAQs either consisted of recall periods of usual 7-days (Usual-week PAQs) within the past 12 months or during the past 7-days (Past-week PAQs); and 3) PAQs were interview-administered. The COSMIN taxonomy was utilised to critically appraise study quality and a previously established psychometric criteria employed to evaluate the overall psychometric qualities.

RESULTS

Following screening, 42 studies were examined to determine the psychometric properties of 20 PAQs, with the majority of studies demonstrating good to excellent ratings for methodological quality. For convergent validity (i.e., the relationship between PAQs and other measures), similar overall associations were found between Past-week PAQs and Usual-week PAQs. However, PAQs were more strongly associated with direct measures of physical activity (e.g., accelerometer) than indirect measures of physical activity (i.e., physical fitness), irrespective of recall methods. Very few psychometric properties were examined for each PAQ, with the majority exhibiting poor ratings in psychometric quality. Only a few interview-administered PAQs exhibited positive ratings for a single psychometric property, although the other properties were either rated as poor or questionable, demonstrating the limitations of current PAQs.

CONCLUSION

Accordingly, further research is necessary to explore a greater number of psychometric properties, or to develop new PAQs by addressing the psychometric limitations identified in the current review.

Methods for evaluating effects of unloader knee braces on joint health: a review

The paper aims to provide a state-of-the-art review of methods for evaluating the effectiveness and effect of unloader knee braces on the knee joint and discuss their limitations and future directions. Unloader braces are prescribed as a non-pharmacological conservative treatment option for patients with medial knee osteoarthritis to provide relief in terms of pain reduction, returning to regular physical activities, and enhancing the quality of life. Methods used to evaluate and monitor the effectiveness of these devices on patients' health are categorized into three broad categories (perception-, biochemical-, and morphology-based), depending upon the process and tools used. The main focus of these methods is on the short-term clinical outcome (pain or unloading efficiency). There is a significant technical, research, and clinical literature gap in understanding the short- and long-term consequences of these braces on the tissues in the knee joint, including the cartilage and ligaments. Future research directions may complement existing methods with advanced quantitative imaging (morphological, biochemical, and molecular) and numerical simulation are discussed as they offer potential in assessing long-term and post-bracing effects on the knee joint.

The joint contribution of physical activity, insomnia symptoms, and smoking to the cost of short-term sickness absence

Physical inactivity has been associated with both insomnia symptoms and smoking. Further, they are all independently associated with increased sickness absence (SA) from work. However, joint contribution of either physical activity (PA) with insomnia symptoms or with smoking to SA and, especially, their direct cost for the employer is poorly understood. Therefore, we aimed to examine these joint associations with short-term (<15 days) SA cost. The Helsinki Health Study is a cohort of midlife employees of the City of Helsinki, Finland (baseline n = 8960, response rate 67%). During 2000-2002, the participants were mailed a survey questionnaire that gathered information on health behavior and sociodemographic characteristics. SA, salary, and time of employment were followed up through the employer's personnel register between 2002 and 2016 for those with a written consent to the use of their register data (78% of the participants). Individual salary data were used to calculate the direct cost of short-term SA. Data were analyzed with a two-part model. Inactive participants with frequent insomnia symptoms had 2526€ (95% CI 1736€-3915€) higher cost of short-term SA than vigorously active participants without insomnia symptoms. Furthermore, inactive smokers had 4166€ (95% CI 2737€-5595€) higher cost for the employer over the follow-up than vigorously active non-smokers. In conclusion, this study showed that PA and insomnia symptoms as well as PA and smoking are jointly associated with short-term SA cost. The results emphasize encouraging employers to improve work environments so that they promote active lifestyle, good sleep, and non-smoking in order to reduce the cost of SA.

Achilles tendon structure is negatively correlated with body mass index, but not influenced by statin use: A cross-sectional study using ultrasound tissue characterization

Introduction

Statins are widely used to inhibit cholesterol production in the liver among people with hypercholesterolemia. A recent epidemiological study in the UK has shown that statin use (unlike elevated BMI) is not associated with an increased risk of Achilles tendon rupture. However, because of laboratory reports suggesting a negative influence of statins on tenocyte metabolism, we decided to directly compare the Achilles tendon structure (cross-sectional area and longitudinal collagen organization) in regular statin users compared to non-users.

Methods

We conducted ultrasound tissue characterization (UTC) of the Achilles tendon in statin users and a comparison group of similar age and gender. Statin users and control participants were recruited from May 10 2015 to February 17 2017 through a cardiovascular health centre and from the general community. Cross-sectional area of the Achilles tendon and longitudinal collagen organization (% type I echoes) were assessed using quantitative ultrasound tissue characterization by a blinded observer at a predetermined location (2 cm proximal to the calcaneus).

Results

Sixty-six individuals who were either taking statins for at least one year (ST, n = 33) or a comparison group who had never taken statins (CG, n = 33) were included in the study. The Achilles tendon cross-sectional area (ST 59.7 (13) mm², CG 59.9 (8.5) mm²) and proportion of echo-type I patterns [ST 70 (10)%, CG 74 (13)%] were equivalent in the two groups. In contrast, there was a negative correlation between BMI (r_s = -0.25, p = 0.042) and type I echo values. Obese individuals demonstrated a significantly lower percentage of type I echoes (62 (11)%) than individuals of normal body mass index (73 (10)% p<0.05).

Conclusion

These findings demonstrate that there is no evidence of a negative statin influence on Achilles tendon structure. Given earlier reports that the risk of Achilles injury is equivalent in statin users and non-users, weightbearing exercise may be prescribed without placing the Achilles tendon at a higher risk of injury than among the general population. The results of this study are consistent with the known negative effects of elevated BMI on tendon structure, suggesting that an assessment of the Achilles tendons prior to prescribing weightbearing exercise may be prudent in obese individuals.

Validation of two short questionnaires assessing physical activity in colorectal cancer patients

Background

In order to investigate the impact of adherence to recommendations of physical activity and sedentary time on health outcomes in clinical trials, there is a need for feasible tools such as questionnaires that can give representative estimates of these measures. The primary aim of the present study was to validate two such questionnaires and their ability to estimate adherence to the recommendations of physical activity defined as moderate-to- vigorous physical activity or moderate physical activity of at least 150 min/week in colorectal cancer patients. Secondarily, self-reported sedentary time from the HUNT-PAQ was also evaluated.

Methods

Participants from 'The Norwegian dietary guidelines and colorectal cancer survival-study’ (CRC-NORDIET study) completed two short questionnaires; the NORDIET-FFQ (n = 78) and the HUNT-PAQ (n = 77). The physical activity monitor SenseWear Armband Mini was used as the reference method during seven consecutive days.

Results

The NORDIET-FFQ provided better estimates of time in moderate-to- vigorous physical activity and moderate physical activity than the HUNT-PAQ. The NORDIET-FFQ was unable to rank individual time in moderate-to- vigorous physical activity and moderate physical activity (Spearman’s rho = 0.08, p = 0.509 and Spearman’s rho rho = 0.01, p = 0.402, respectively). All intensities were under-reported by the HUNT-PAQ, but ranking of individual time in moderate physical activity and sedentary time were acceptable among women only (Spearman’s rho = 0.37, p = 0.027 and Spearman’s rho = 0.36, p = 0.035, respectively). The HUNT-PAQ correctly classified 71% of those not meeting the recommendations (sensitivity), and the NORDIET-FFQ correctly classified 63% of those who met the recommendations (specificity). About 67% and 33% reported to meet the recommendation of moderate-to- vigorous physical activity with the NORDIET-FFQ and HUNT-PAQ, respectively, whereas 55% actually met the moderate-to- vigorous physical activity according to the SenseWear Armband Mini.

Conclusions

The NORDIET-FFQ provided better specificity and better estimates of PA than the HUNT-PAQ. The HUNT-PAQ provided better sensitivity, and provided better ranking of PA and sedentary time among women than NORDIET-FFQ. It is important to be aware of the limitations documented in the present study.

Trial registration

The study is registered on the National Institutes of Health Clinical Trials (Identifier: NCT01570010). Registered 4 April 2012.

The multiple sclerosis work difficulties questionnaire: translation and cross-cultural adaptation to Turkish and assessment of validity and reliability

Purpose: To linguistically and culturally adapt the Multiple Sclerosis Work Difficulties Questionnaire-23 (MSWDQ-23) for use in Turkey, and to examine its reliability and validity. Methods: Following standard forward-back translation of the MSWDQ-23, it was administered to 124 people with multiple sclerosis (MS). Validity was evaluated using related outcome measures including those related to employment status and expectations, disability level, fatigue, walking, and quality of life. Randomly selected participants were asked to complete the MSWDQ-23 again to assess test-retest reliability. Results: Confirmatory factor analysis on the MSWDQ-23 demonstrated a good fit for the data, and the internal consistency of each subscale was excellent. The test-retest reliability for the total score, psychological/cognitive barriers, physical barriers, and external barriers subscales were high. The MSWDQ-23 and its subscales were positively correlated with the employment, disability level, walking, and fatigue outcome measures. Conclusions: This study suggests that the Turkish version of MSWDQ-23 has high reliability and adequate validity, and it can be used to determine the difficulties faced by people with multiple sclerosis in workplace. Moreover, the study provides evidence about the test-retest reliability of the questionnaire. Implications for rehabilitation Multiple sclerosis affects young people of working age. Understanding work-related problems is crucial to enhance people with multiple sclerosis likelihood of maintaining their job. The Multiple Sclerosis Work Difficulties Questionnaire-23 (MSWDQ-23) is a valid and reliable measure of perceived workplace difficulties in people with multiple sclerosis: we presented its validation to Turkish. Professionals working in the field of vocational rehabilitation may benefit from using the MSWDQ-23 to predict the current work outcomes and future employment expectations.

Routine Assessment and Promotion of Physical Activity in Healthcare Settings: A Scientific Statement From the American Heart Association

Physical inactivity is one of the most prevalent major health risk factors, with 8 in 10 US adults not meeting aerobic and muscle-strengthening guidelines, and is associated with a high burden of cardiovascular disease. Improving and maintaining recommended levels of physical activity leads to reductions in metabolic, hemodynamic, functional, body composition, and epigenetic risk factors for noncommunicable chronic diseases. Physical activity also has a significant role, in many cases comparable or superior to drug interventions, in the prevention and management of >40 conditions such as diabetes mellitus, cancer, cardiovascular disease, obesity, depression, Alzheimer disease, and arthritis. Whereas most of the modifiable cardiovascular disease risk factors included in the American Heart Association’s My Life Check - Life’s Simple 7 are evaluated routinely in clinical practice (glucose and lipid profiles, blood pressure, obesity, and smoking), physical activity is typically not assessed. The purpose of this statement is to provide a comprehensive review of the evidence on the feasibility, validity, and effectiveness of assessing and promoting physical activity in healthcare settings for adult patients. It also adds concrete recommendations for healthcare systems, clinical and community care providers, fitness professionals, the technology industry, and other stakeholders in order to catalyze increased adoption of physical activity assessment and promotion in healthcare settings and to contribute to meeting the American Heart Association’s 2020 Impact Goals.

A systematic literature review of reviews on techniques for physical activity measurement in adults: a DEDIPAC study

The links between increased participation in Physical Activity (PA) and improvements in health are well established. As this body of evidence has grown, so too has the search for measures of PA with high levels of methodological effectiveness (i.e. validity, reliability and responsiveness to change). The aim of this “review of reviews” was to provide a comprehensive overview of the methodological effectiveness of currently employed measures of PA, to aid researchers in their selection of an appropriate tool. A total of 63 review articles were included in this review, and the original articles cited by these reviews were included in order to extract detailed information on methodological effectiveness.

Self-report measures of PA have been most frequently examined for methodological effectiveness, with highly variable findings identified across a broad range of behaviours. The evidence-base for the methodological effectiveness of objective monitors, particularly accelerometers/activity monitors, is increasing, with lower levels of variability observed for validity and reliability when compared to subjective measures. Unfortunately, responsiveness to change across all measures and behaviours remains under-researched, with limited information available.

Other criteria beyond methodological effectiveness often influence tool selection, including cost and feasibility. However, researchers must be aware of the methodological effectiveness of any measure selected for use when examining PA. Although no “perfect” tool for the examination of PA in adults exists, it is suggested that researchers aim to incorporate appropriate objective measures, specific to the behaviours of interests, when examining PA in free-living environments.
