Test Retest Reliability

The Synchronised Nutrition and Activity Program for Adults (SNAPA™) was developed to address the need for accurate, reliable, feasible, inexpensive and low-burden methods for assessing specific dietary and physical activity behaviours in adults. Short-term test–retest reliability of SNAPA™ was assessed in forty-four adults (age 41·4 (sd 17·3) years) who completed SNAPA™ twice in 1 day. Concurrent validity against direct dietary observation and combined heart rate and accelerometry was assessed in seventy-seven adults (age 34·4 (sd11·1) years). Test–retest reliability revealed no substantial systematic shifts in mean values of the outcome variables: percentage of food energy from fat (% fat), number of portions of fruit and vegetables (FV) and minutes of moderate-to-vigorous physical activity (MVPA). For lunchtime dietary intake, the mean match rate between food items reported using SNAPA™ and those observed was 81·7 %, with a phantom rate of 5·6 %. Pearson's correlations between SNAPA™ and the reference methods ranged from 0·27 to 0·56 for % fat, FV portions and minutes of MVPA. For % fat and FV intake, there was no fixed or proportional bias, and mean differences between the methods (SNAPA™ − reference) were 5·1 % and 0 portions, respectively. For minutes of MVPA, a fixed bias of − 28 min was revealed when compared with all minutes of MVPA measured by combined heart rate and accelerometry, whereas a proportional bias (slope 1·47) was revealed when compared with minutes carried out in bouts ≥ 10 min. SNAPA™ is a promising tool for measuring specific energy balance behaviours, though further work is required to improve accuracy for physical activity behaviours.

Purpose. To examine psychometric properties of a Commitment to Physical Activity Scale for Adolescents (CPASA). Design. Two test-retest studies and a prospective study, approved by a university institutional review board, were conducted in midwestern U.S. urban areas. Setting. The first test-retest study occurred in four community centers, the second test-retest study took place in a community school, and the prospective study occurred in eight middle schools. Subjects. To measure commitment at baseline and 1 week later, 51 girls in the first test-retest study completed an original 26-item scale, and 91 in the second test-retest study completed a revised 11-item scale. In the prospective study, 503 girls completed the 11-item scale. Measures. Commitment was measured via the CPASA. After completing the CPASA, girls in the prospective study wore ActiGraph GT3X-plus accelerometers that measured light, moderate, and vigorous physical activity (LMVPA) and moderate to vigorous physical activity (MVPA). Analysis. Internal consistency and test-retest reliability were estimated. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to cross-validate the factor structure. Results. For the 11-item CPASA, Cronbach α ranged from .81 to .82, and test-retest reliability was .88. Both EFA and CFA indicated a single factor. The scale was significantly correlated with LMVPA (r = .10) and MVPA (r = .11). Conclusion. The 11-item CPASA demonstrated acceptable reliability and validity with girls.

AbstractThe purpose of this study was to examine the convergent validity and test–retest reliability of the Oxford Physical Activity Questionnaire (OPAQ), a self-administered questionnaire designed to assess the activity patterns of adolescents. The test–retest reliability of the OPAQ was assessed by administering the questionnaire on two occasions separated by 1 week (N = 87, mean age = 13.1 ± .9). Intraclass correlation (ICC) was used to examine the test–retest reliability of the OPAQ. The convergent validity of the OPAQ was evaluated using Caltrac accelerometers worn consecutively for 4 days (N = 51, mean age = 12.6 ± .5). Spearman's rank-order correlation was used to examine the convergent validity of the questionnaire. ICCs ranged from .76 to .91 and reliability was higher for males (r = .89) than females (r = .78). Correlations between self-reported physical activity and Caltrac accelerometer counts were related to vigorous physical activity (r = .33, p = .01) and moderate to vigorous activity (r = .32, p = .02). The OPAQ has excellent test–retest reliability and acceptable validity in comparison to other measures of youth physical activity.

Test Retest Reliability

Background:The Multimedia Activity Recall for Children and Adults (MARCA) is a computerized recall instrument that records use of time during 24 hr the previous day and has been developed to address limitations of current self-report physical activity measures for those in advanced age.Methods:Test–retest reliability and convergent validity of the adult MARCA were assessed in a sample of 45 advanced-age adults (age 84.9SD ±1.62 yr) as a subsample of the Life and Living in Advanced-Age Cohort Study New Zealand (LiLACS NZ). Test–retest methods required participants to recall the previous day’s activity using the MARCA twice within the same day. Convergent validity was assessed against accelerometry.Results:Test–retest reliability was high, with ICCs greater than .99 for moderate to vigorous physical activity (MVPA) and physical activity level (PAL). Compared with accelerometry, the MARCA demonstrated validity comparable to other self-report instruments with Spearman’s coefficients of .34 and .59 for time spent in nonsedentary physical activity and PAL.Conclusion:The MARCA is a valid and reliable self-report tool for physical activity behaviors in advanced-age adults.

Background:The purpose of this study was to determine 1) the test-retest reliability of adult accelerometer-measured physical activity, and 2) how data processing decisions affect physical activity levels and test-retest reliability.Methods:143 people wore the ActiGraph accelerometer for 2 7-day periods, 1 to 4 weeks apart. Five algorithms, varying nonwear criteria (20 vs. 60 min of 0 counts) and minimum wear requirements (6 vs. 10 hrs/day for ≥ 4 days) and a separate algorithm requiring ≥ 3 counts per min and ≥ 2 hours per day, were used to process the accelerometer data.Results:Processing the accelerometer data with different algorithms resulted in different levels of counts per day, sedentary, and moderate-to-vigorous physical activity. Reliability correlations were very good to excellent (ICC = 0.70−0.90) for almost all algorithms and there were no significant differences between physical activity measures at Time 1 and Time 2.Conclusions:This paper presents the first assessment of test-retest reliability of the Actigraph over separate administrations in free-living subjects. The ActiGraph was highly reliable in measuring activity over a 7-day period in natural settings but data were sensitive to the algorithms used to process them.

Abstract Objective Idiopathic inflammatory myopathies (IIM) cause proximal muscle weakness, which affect activities of daily living. Wearable physical activity monitors (PAMs) objectively assess continuous activity with potential clinical usefulness in IIM assessment. We examined the psychometric characteristics for PAM outcomes in IIM. Methods Adult IIM patients were prospectively evaluated (baseline, 3 and 6-months) in an observational study. A waist-worn PAM (ActiGraph GT3X-BT) assessed average step counts/min, peak 1-min cadence, and vector magnitude/min. Validated myositis core set measures (CSM) including manual muscle testing (MMT), physician global disease activity (MD global), patient global disease activity (Pt global), extra-muscular disease activity (Ex-muscular global), HAQ-DI, muscle enzymes, and patient-reported physical function were evaluated. Test-retest reliability, construct validity, and responsiveness were determined for PAM measures and CSM using Pearson correlations and other appropriate analyses. Results 50 adult IIM patients enrolled [mean (SD) age, 53.6 (±14.6); 60% female, 94% Caucasian]. PAM measures showed strong test-retest reliability, moderate-to-strong correlations at baseline with MD global (r=-0.37- -0.48), Pt-global (r=-0.43- -0.61), HAQ-DI (r=-0.47- -0.59) and MMT (r = 0.37–0.52), and strong discriminant validity for categorical MMT and HAQ-DI. Longitudinal association with MD global (r=-0.38- -0.44), MMT (r = 0.50–0.57), HAQ-DI (r=-0.45- -0.55), and functional tests (r = 0.30–0.65) were moderate-to-strong. PAM measures were responsive to MMT improvement (≥10%) and moderate-to-major improvement on ACR/EULAR myositis response criteria. Peak 1-min cadence had the largest effect size and Standardized Response Means (SRMs). Conclusion PAM measures showed promising construct validity, reliability, and longitudinal responsiveness; especially peak 1-min cadence. PAMs provide valid outcome measures for future use in IIM clinical trials.

Fear Avoidance Beliefs Questionnaire

AbstractObjectivesFear-avoidance beliefs questionnaire (FABQ) is a self-report, valid and reliable questionnaire to quantify fear and avoidance beliefs related to physical activity and work. Furthermore, it can be used to predict prolong disability in patients with non-specific neck pain. Although it was originally developed to manage patients with low back pain, it has also been studied in individuals with neck pain. This questionnaire was translated into several languages following reports of potential benefits in patients with neck pain. Recently, Thai neck clinical trials, international multi-centre trials and data sharing are growing throughout the world but no validated Thai version of the FABQ is available for clinical and research uses. Our objectives were to translate and cross-culturally adapt the FABQ into Thai version and evaluate its psychometric properties in Thai patients with non-specific neck pain.MethodsCross-cultural translation and adaptation of the FABQ were conducted according to standard guidelines. A total of 129 participants with non-specific neck pain were invited to complete the Thai versions of the FABQ (FABQ-TH), neck disability index and visual analogue scale for pain intensity. Psychometric evaluation included exploratory factor analysis, internal consistency, test-retest reliability, agreement, and convergent validity. Thirty participants completed the FABQ-TH twice with a 48-h interval between tests to assess the test-retest reliability.ResultsFactor analysis identified four components for the FABQ-TH (66.69% of the total variance). The intraclass correlation coefficient of test-retest reliability was excellent for the total score (0.986), work attitudes (0.995), physical activity attitudes (0.958), physical activity experiences (0.927), and expected recovery (0.984). Cronbach’s alpha for internal consistency was excellent (range 0.87–0.88) for all items. The minimal detectable change of the FABQ-TH was 5.85. The FABQ-TH correlated to its subscales (range 0.470–0.936), indicating the strongest association with work attitude. The weakest correlation was observed between the FABQ-TH and disability (rs=0.206, p=0.01). Missing data and significant floor or ceiling effects were not found.ConclusionsThe Thai version of the FABQ for non-specific neck pain was successfully adapted. It is a valid and reliable instrument to quantify fear and avoidance beliefs among patients with non-specific neck pain who speak and read Thai.

Abstract Background Childhood obesity has increased remarkably in low and middle-income (LMIC) countries. Movement behaviors (physical activity, screen time, and sleep) are crucial in the development of overweight and obesity in young children. Yet, few studies have investigated the relationship between children’s movement behaviors and parenting practices because validated measures for use among families from LMIC are lacking. This study evaluated the psychometric properties of previously validated measures of young children’s physical activity, screen time, and sleep and parenting practices, translated and culturally adapted to Brazilian families. Methods A total of 78 parent-child dyads completed an interviewer-administered survey twice within 7 days. Child physical activity, sedentary time and sleep were concurrently measured using a wrist-worn accelerometer. Internal consistency and test-retest reliability was assessed using McDonald’s Omega and Intraclass Correlation Coefficients (ICC’s). Concurrent validity was evaluated by calculating Spearman correlations between parent reported child behaviors and accelerometer measured behaviors. Results Seventeen of the 19 parenting practices scales exhibited acceptable internal consistency reliability (Ω ≥ 0.70). Test-retest reliability ICC’s were acceptable and ranged from 0.82 - 0.99. Parent reported child physical activity was positively correlated with objectively measured total movement (rho= 0.29 - 0.46, p < .05) and energetic play (rho= 0.29 – 0.40, p < .05). Parent reported child screen time was positively correlated with objectively measured sedentary time; (rho = 0.26, p < .05), and inversely correlated with total movement (rho = - 0.39 – - 0.41, p < .05) and energetic play (rho = - 0.37 – - 0.41, p < .05). Parent reported night-time sleep duration was significantly correlated with accelerometer measured sleep duration on weekdays (rho = 0.29, p < .05), but not weekends. Conclusions Measurement tools to assess children’s movement behaviors and parenting practices, translated and culturally adapted for use in Brazilian families, exhibited acceptable evidence of concurrent validity, internal consistency, and test-retest reliability.

Abstract Background Validation of self-reported tools, such as physical activity (PA) questionnaires, is crucial. The aim of this study was to determine test-retest reliability, internal consistency, and the concurrent, construct, and predictive validity of the short semi-quantitative Physical Activity Unit 7 item Screener (PAU-7S), using accelerometry as the reference measurement. The effect of linear calibration on PAU-7S validity was tested. Methods A randomized sample of 321 healthy children aged 8–16 years (149 boys, 172 girls) from the nationwide representative PASOS study completed the PAU-7S before and after wearing an accelerometer for at least 7 consecutive days. Weight, height, and waist circumference were measured. Cronbach alpha was calculated for internal consistency. Test-retest reliability was determined by intra-class correlation (ICC). Concurrent validity was assessed by ICC and Spearman correlation coefficient between moderate to vigorous PA (MVPA) derived by the PAU-7S and by accelerometer. Concordance between both methods was analyzed by absolute agreement, weighted kappa, and Bland-Altman statistics. Multiple linear regression models were fitted for construct validity and predictive validity was determined by leave-one-out cross-validation. Results The PAU-7S overestimated MVPA by 18%, compared to accelerometers (106.5 ± 77.0 vs 95.2 ± 33.2 min/day, respectively). A Cronbach alpha of 0.76 showed an acceptable internal consistency of the PAU-7S. Test-retest reliability was good (ICC 0.71 p < 0.001). Spearman correlation and ICC coefficients of MVPA derived by the PAU-7S and accelerometers increased from 0.31 to 0.62 and 0.20 to 0.62, respectively, after calibration of the PAU-7S. Between-methods concordance improved from a weighted kappa of 0.24 to 0.50 after calibration. A slight reduction in ICC, from 0.62 to 0.60, yielded good predictive validity. Multiple linear regression models showed an inverse association of MVPA with standardized body mass index (β − 0.162; p < 0.077) and waist to height ratio (β − 0.010; p < 0.014). All validity dimensions were somewhat stronger in boys compared to girls. Conclusion The PAU-7S shows a good test-retest reliability and acceptable internal consistency. All dimensions of validity increased from poor/fair to moderate/good after calibration. The PAU-7S is a valid instrument for measuring MVPA in children and adolescents.
