AbstractObjectiveTo assess convergent validity, factorial validity, test–retest reliability and internal consistency of a diet quality food behaviour checklist (FBC) for low-literate, low-income Spanish speakers.DesignParticipants (n 90) completed three dietary recalls, the Spanish-language version of the US Department of Agriculture (USDA) Household Food Security Survey Module (HFSSM) and the Spanish-language FBC. Factor structure was examined using principal component analysis. Spearman correlation coefficients between FBC item responses and nutrient intakes from 24 h recalls were used to estimate convergent validity. Correlation coefficients were also calculated between FBC item responses at two time points in another group of participants (n 71) to examine test–retest reliability. Cronbach's α coefficient was determined for items within each sub-scale.SettingNon-profit community agencies serving low-income clients, migrant farm worker camps and low-income housing sites in four California counties.SubjectsSpanish-speaking women (n 161) who met income eligibility for the SNAP-Ed (Supplemental Nutrition Assistance Program–Education).ResultsFactor analysis resulted in six sub-scales. Responses to nineteen food behaviour items were significantly correlated with hypothesized 24 h recall data (with a maximum correlation of 0·44 for drinking milk and calcium) or the USDA HFSSM (0·42 with the food security item). Coefficients for test–retest reliability ranged from 0·35 to 0·79. Cronbach's α ranged from 0·49 for the diet quality sub-scale to 0·80 for the fruit and vegetable sub-scale.ConclusionsThe twenty-two-item FBC and instruction guide will be used to evaluate USDA community nutrition education interventions with low-literate Spanish speakers. This research contributes to the body of knowledge about this at-risk population in California.

Objectives: This study conducted a linguistic and psychometric evaluation of the Chinese Counseling Competencies Scale-Revised (CCS-R).Methods: The Chinese CCS-R was created from the original English version using a standard forward-backward translation process. The psychometric properties of the Chinese CCS-R were examined in a cohort of 208 counselors-in-training by two independent raters. Fifty-three counselors-in-training were asked to undergo another counseling performance evaluation for the test-retest. The confirmatory factor analysis (CFA) was conducted for the Chinese CCS-R, followed by internal consistency, test-retest reliability, inter-rater reliability, convergent validity, and concurrent validity.Results: The results of the CFA supported the factorial validity of the Chinese CCS-R, with adequate construct replicability. The scale had a McDonald's omega of 0.876, and intraclass correlation coefficients of 0.63 and 0.90 for test-retest reliability and inter-rater reliability, respectively. Significantly positive correlations were observed between the Chinese CCS-R score and scores of performance checklist (Pearson's γ = 0.781), indicating a large convergent validity, and knowledge on drug abuse (Pearson's γ = 0.833), indicating a moderate concurrent validity.Conclusion: The results support that the Chinese CCS-R is a valid and reliable measure of the counseling competencies.Practice implication: The CCS-R provides trainers with a reliable tool to evaluate counseling students' competencies and to facilitate discussions with trainees about their areas for growth.

Abstract Background The main aim of post-mastectomy breast reconstruction is to improve the patient’s quality of life, which makes high-quality and validated patient-reported outcome measurements essential. None of the established instruments include evaluation of donor-site morbidity, such as impact on upper extremity and back function, when a latissimus dorsi (LD) muscle is used; and BREAST-Q LD questionnaire was therefore recently developed for this purpose. The aim of this study was to translate into Swedish and culturally adapt the BREAST-Q LD questionnaire’s two subscales, appearance and function, and perform a psychometric evaluation of the subscales in a Swedish population of patients. Methods This was a cross-sectional study. The questionnaire was translated according to established guidelines. The questionnaires were sent to all patients operated using an LD flap between 2007 and 2017. Internal consistency was assessed using Cronbach’s α. Inter-item correlations and corrected item-total correlations were calculated using the Pearson’s correlation coefficient. Convergent validity was evaluated by comparing the BREAST-Q LD questionnaire to the Western Ontario Osteoarthritis of the Shoulder Index, using the Spearman correlation coefficient. Test–retest reliability was tested with intraclass correlation coefficients (ICCs), and the coefficient of variation and Bland–Altman plots were drawn. Floor and ceiling effects were calculated. Known-group validation was tested by comparing scores from the patients and from normal controls using the Mann–Whitney U-test and by calculating eta squared effect size. Results The questionnaires were sent to 176 eligible patients and 125 responded (71%). The patients had been operated a mean of 6.6 years ago, and most (92%) had previous radiation. Internal consistency was satisfactory for both subscales. The correlation coefficients between questions were r > 0.30 for all items of both scales. The corrected item-total correlation coefficient ranged from 0.62 to 0.90. As hypothesised, the function scale was correlated with the WOOS “Physical symptoms” subscale. Reliability was adequate according to the ICCs. The ceiling effect threshold for the appearance scale was reached and that for the back scale was almost reached. There were significant differences between patients and controls, in the hypothesised direction. Conclusions The results of this study support a good internal consistency, convergent validity, test–retest reliability and known-group validation for the Swedish BREAST-Q LD questionnaire. However, it may be difficult to discriminate between patients with very mild and those with no symptoms using the appearance scale. Trial registration: ClinicalTrials.Gov identifier NCT04526561.

Abstract Objective The NIH Toolbox for Assessment of Neurological and Behavioral Function (NIHTB) was developed under contract from the National Institutes of Health to create a set of easy-to-administer neuropsychological measures, for use across the lifespan (ages 3-85). The NIHTB Cognition Battery (NIHTB-CB) includes two language measures that were developed, calibrated, and normed separately in English and Spanish. This analysis presents the test-retest reliability and construct validity of the Spanish-language picture vocabulary test (S-PVT) and oral reading recognition test (S-ORRT) among adults. Participants and Method Participants were adults age 18-85 who took part in the NIHTB norming study in Spanish (N = 408, Age: M = 44.1, SD = 16.7; Education: M = 10.7, SD = 4.3; 65.0% female). Of these, 48 repeated the battery 1 week later. Both the S-PVT and the S-ORRT were administered using computer adaptive testing and scored using item response theory. Spearman’s correlations were used to evaluate test-retest reliability. Convergent validity was evaluated by correlating S-PVT scores with scores on the Batería-III Woodcock-Muñoz Vocabulario Sobre Dibujos, and by correlating S-ORRT scores with scores on a 48-item version of the Word Accentuation Test. Adjusted Spearman’s correlations and general linear models related scores to age, education, and sex. Results Both the S-PVT (ρ = 0.87, p < .001) and the S-ORRT (ρ = 0.88, p < .001) demonstrated good test-retest reliability. Good convergent validity was found for both the S-PVT (ρ = 0.76, p < .001) and the S-ORRT (ρ = 0.65, p < .001). Scores on the S-PVT were positively related to education (ρ = 0.38, p < .001), and scores on the S-ORRT were negatively related to age (ρ = -0.18, p < .01) and positively related to education (ρ = 0.30, p < .001). Conclusions The Spanish language measures of the NIHTB-CB demonstrated acceptable reliability and validity, suggesting they can be used to measure language ability among Spanish-speaking adults in the United States.

Background There is a high incidence of falls in older adults with knee osteoarthritis (OA). Adequate dynamic balance and mobility reduce the risk of falls; however, there are currently no validated, advanced tests of dynamic balance and mobility for individuals with knee OA. Objective The purpose of this study was to determine the convergent validity, known-groups validity, and test-retest reliability of a dynamic test of balance and mobility, the Community Balance and Mobility Scale (CB&M), in a knee OA population. Design A cross-sectional design was used. Methods Twenty-five individuals aged 50 years and older with medial knee OA and an equal number of healthy controls completed the CB&M and other tests of balance and mobility, including the Berg Balance Scale, the Timed “Up & Go” Test, a test of maximal single-leg stance time, and the 10-Meter Walk Test (self-selected and fast walking speed). Convergent validity of balance tests with the CB&M was assessed using Pearson product moment correlation coefficients, and known-groups validity was assessed using independent t tests. Test-retest reliability of the CB&M was assessed using intraclass correlation coefficients (ICCs) and standard error of measurement (SEM). Results Scores on the CB&M were significantly correlated with all measures of balance and mobility for those with knee OA. There were significant differences in CB&M scores between groups. Scores on the CB&M were highly reliable in people with knee OA (ICC=.95, 95% confidence interval [95% CI]=0.70 to 0.99; SEM=3, 95% CI=2.68 to 4.67). Limitations Few participants had severe knee OA. Conclusions The CB&M displayed moderate convergent validity, excellent known-groups validity, and high test-retest reliability. The CB&M can be used as a valid and reliable tool to assess dynamic balance and mobility deficits in people with knee OA.

Objective: Walking assessment is an important aspect of rehabilitation practice; yet, clinicians have few psychometrically sound options for evaluating walking in highly ambulatory children. The purpose of this study was to evaluate the validity and reliability of two new measures of walking function—the Obstacles and Curb tests—relative to the 10-Meter Walk test and Timed Up and Go test in children with spina bifida or cerebral palsy. Methods: A total of 16 ambulatory children with spina bifida ( n=9) or cerebral palsy ( n=7) (9 boys; mean age 7years, 7months; standard deviation 3years, 4months) and 16 age- and gender-matched typically developing children participated. Children completed the walking tests, at both self-selected and fast speeds, twice. To evaluate discriminative validity, scores were compared between typically developing and spina bifida/cerebral palsy groups. Within the spina bifida/cerebral palsy group, inter-test correlations evaluated convergent validity and intraclass correlation coefficients evaluated within-session test–retest reliability. Results: At fast speeds, all tests showed discriminative validity ( p<0.006 for typically developing and spina bifida/cerebral palsy comparisons) and convergent validity ( rho=0.81–0.90, p⩽0.001, for inter-test correlations). At self-selected speeds, only the Obstacles test discriminated between groups ( p=0.001). Moderately strong correlations ( rho=0.73–0.78, p⩽0.001) were seen between the 10-Meter Walk test, Curb test, and Timed Up and Go test. Intraclass correlation coefficients ranged from 0.81 to 0.97, with higher test–retest reliability for tests performed at fast speeds rather than self-selected speeds. Conclusion: The Obstacles and Curb tests are promising measures for assessing walking in this population. Performing tests at fast walking speeds may improve their validity and test–retest reliability for children with spina bifida/cerebral palsy.

Objective To compare the test-retest reliability and validity of three simple maximal isometric back extensor strength (BES) assessment protocols with different test postures, and to recommend an optimal clinical protocol to quantify BES. Methods Asymptomatic adults, aged over 45 years, were assessed for maximal isometric BES using external fixation of dynamometers, with the subject in standing, prone and sitting positions, respectively. Measurements were repeated at a one-week interval to examine test-retest reliability. Validation was performed by comparing with results obtained from isokinetic dynamometer assessments. Results Out of a total of 60 included participants, intra-class correlation coefficients (ICC) were 0.92, 0.93 and 0.90 in standing, prone and sitting positions, respectively. Correlation analyses revealed acceptable convergent validity in the standing and prone position (r = 0.50 and 0.54, respectively), whereas tests conducted in the sitting position showed a relatively low validity (r = 0.32). Among the three protocols, measurement error was lowest in the prone position. Conclusions Maximal isometric BES assessment in the prone position was shown to be the most reliable and valid protocol, and may be considered the preferred option for assessing BES in clinical practice.

AbstractThe design fluency test (DFT) has been reported to predict successful sports performance of soccer players and has therefore been in the spotlight of sport psychology research. There is, however, a lack of research regarding the psychometric properties of the DFT in elite sports. Thus, the aim of this research was to provide findings of test–retest reliability, practice effects and the diagnostic power of the DFT. Multiple studies of youth and adult elite athletes, as well as nonathlete students, were conducted in applied settings. Test–retest relationship demonstrated poor to acceptable short-term and long-term correlations. Furthermore, significant changes between test and retest were obtained in some variables that differed among samples. The differential value of the DFT was corroborated by significant differences between adolescent students and adolescent elite soccer players. Regarding the prospective value, significant partial correlation coefficients were found between DFT scores and volleyball performance in adult elite players. Although our research partially confirmed previous findings on the differential and prospective power of the DFT, the findings on test–retest reliability indicate that the DFT cannot be recommended for application in sports. The psychometric properties—in particular the findings on test–retest reliability—of the DFT have to be improved before research can be carried out on the application for the selection of team sport athletes and for the prediction of future success in team sports. Further research is needed to develop a scientific instrument for the assessment of game intelligence.

Abstract Background Fluid intelligence deficits affect executive functioning and social behaviors in patients with schizophrenia. To help clinicians manage fluid intelligence deficits, a psychometrically sound measure is needed. The purposes of this study were to examine the test–retest reliability and convergent validity of the Test of Nonverbal Intelligence-Fourth Edition (TONI-4) assessing fluid intelligence in patients with schizophrenia. Methods A total of 103 patients with stable condition were assessed with the TONI-4 twice with a 4-week interval to examine the test–retest reliability. We further used the Montreal Cognitive Assessment (MoCA) and the Tablet-Based Symbol Digit Modalities Test (T-SDMT) to examine the convergent validity of the TONI-4. Results The intra-class correlation coefficient was 0.73 for the TONI-4. The percentages of standard error of measurement and minimal detectable change for the TONI-4 were 5.1 and 14.2%, respectively. The practice effect of the TONI-4 was small (Cohen’s d = − 0.03). Convergent validity showed small to moderate significant correlations between the TONI-4 and the MoCA as well as the T-SDMT (r = 0.35, p = .011 with the T-SDMT and r = 0.61, p < .001 with the MoCA). The results demonstrated that the TONI-4 had good test–retest reliability, limited random measurement error, and a trivial practice effect. The convergent validity of the TONI-4 was good. Conclusions These findings indicate that the TONI-4 has potential to be a reliable and valid assessment of fluid intelligence in patients with schizophrenia.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P &lt; 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Several dexterity tests have been developed, including the Minnesota Rate of Manipulation Test (MRMT) and a new version, the Minnesota Manual Dexterity Test (MMDT). The objectives of the study were: a) to verify the test-retest reliability of the MMDT; b) to compare the MRMT and the MMDT; c) to study the concurrent validity of the MMDT; and d) to establish reference values for elderly people with the MMDT. Two hundred and forty-seven community-living healthy elderly were evaluated with the MMDT, and two other dexterity tests, the Box and Block Test (BBT) and the Purdue Pegboard (PP). Thirty-five of them were evaluated twice with the MMDT and 44 were evaluated with both the MMDT and MRMT. The results show that the test-retest reliability of the MMDT is acceptable to high (intraclass correlation coefficients of 0.79 to 0.87, depending on the subtest) and the validity of the test is demonstrated by significant correlations between the MMDT, the BBT and the PP (0.63 to 0.67). There is a high correlation (0.85 to 0.95) between the MMDT and the MMRT in spite of different results. The reference values will help occupational therapists to differentiate better between real dexterity difficulties and those that may be attributed to normal aging.
