Background. Considering the lack of valid and reliable food frequency questionnaires (FFQs) for nutritional epidemiological studies in China, it is necessary to develop an effective one for assessing nutrient intake among preschool children. The aim of this study was to evaluate the validity and reliability of newly developed FFQs for assessing food and nutrient intakes among preschool children in Northwest China. Methods. Semiquantitative 67-item FFQs were developed and validated. In total, 326 children (aged 2–6 years) were recruited from three different cities in Northwest China. All subjects were asked to complete the FFQs twice with a six-month interval period for test-retest reliability. Apart from the FFQs, a 3-day food record (3-DFR) was also carried out to evaluate the validity of the FFQs. Results. There was no significant difference in the nutrient intakes of preschool children between the two FFQs ( P > 0.05 ), and these two FFQs demonstrated a positive correlation ( P < 0.05 ). Spearman’s coefficient correlation values ranged from 0.222 (“Selenium”) to 0.832 (“Energy”). The intraclass correlation coefficient values ranged from 0.282 (“Selenium”) to 0.882 (“Energy”). With regards to the validity of FFQs, nutrient intakes from FFQs were greater than 3DR dietary recalls ( P < 0.05 ). After adjusting for total energy and intraindividual variation, all nutrient intakes showed a positive correlation ( P < 0.05 ), and these correlations became stronger. According to the quartiles of nutrient intakes, the exact agreement between the FFQs and 3DR dietary recalls ranged between 40% (“Selenium”) and 70% (“Energy”), and grossly misclassified was low (12.5%). Conclusions. The findings of this study indicate that the designed FFQs exhibit good test-retest reliability and moderate relative validity. Hence, the FFQs can serve as an important tool for the large-scale assessment of food and nutrient intakes among preschool children (in the mentioned areas of China).

Abstract Objective The aim of this study was to investigate the validity and reliability of the Patient Dignity Inventory (PDI) in the Turkish society, which was developed to evaluate dignity-related distress in palliative care patients. Methods One hundred and twenty-seven adults with advanced cancer hospitalized in several clinics of two university hospitals were included in the study. The patients whose Palliative Performance Scale score was at least 40% were recruited to study. The data were collected with a patient demographic form, the Turkish version of Hospital Anxiety and Depression Scale (HADS-TR), and the Turkish version of the PDI (PDI-TR). The PDI-TR was finalized and back-translated after translating into Turkish and obtaining 10 expert opinions. Exploratory and confirmatory factor analysis, internal consistency, concurrent validity, and test–retest reliability analysis were performed. Results The Cronbach's α coefficient of PDI-TR was 0.94. Factor analysis resulted in a five-factor solution, and all items were loaded on factors. Factors were labeled as symptom distress, existential distress, self-confidence, dependency, and supportive care needs and accounted for 68.70% of the overall variance. The model's normed fit index, comparative fit index, and X2/SD were found between acceptable range (0.90, 0.93, and 2.64, respectively). A positive and strong correlation was found between subdimension scores of HADS-TR and the total score of PDI-TR (r = 0.70 for anxiety subdimension; r = 0.73 for depression subdimension). The test–retest reliability was conducted with 32 patients within the sample two weeks after the first application, and no significant difference was found between the two application scores as the result of paired-sample t-test (p > 0.05). An intraclass correlation coefficient of test–retest reliability was r = 0.855. Significance of results PDI-TR was found to be a valid and reliable tool in palliative care patients in Turkish society.

Test Retest Reliability

Objective: To estimate validity and reliability of WTP questionnaire which WTP value can be taken as an indication of the monetary value of health gains, which may carry information regarding the appropriate height of the cost-effectiveness threshold.Methods: Three hundred respondents, in Yogyakarta province, Indonesia, were interviewed during June 2017. We examine a value of WTP associated with the following scenarios: 1) improving moderate condition; 2) extending life during terminal illness, and 3) lifesaving. The interview ascertained maximum hypothetical WTP for one QALY using a dichotomous bidding format with an open-ended final question, along with questions about the socio-economic factors. Concerning validity, the WTP of the 3 versions of hypothetical scenarios were compared as known-group validity and analysis of the sensitivity and specificity was performed. Test-retest reliability and alpha Cronbach were employed to measure internal consistency.Results: Analysis generally confirmed the validity and reliability of the WTP hypothetical scenarios. In terms of known group validity, there was significant difference across two scenarios (treatment v. s lifesaving), but no significant difference between mean WTP for treatment and terminal illness was found. Mean WTP for terminal illness (38 Million IDR) and lifesaving scenario (16 Million IDR) was significantly higher than that of treatment scenario (14 Million IDR). The WTP instrument showed good convergent validity (r=0.784), when comparing correlation between WTP value and utility score. Estimation of scenario’s sensitivity and specificity in deriving expected WTP were 70.33 % and 38.98 %, respectively. The positive and negative predictive values were 64 % and 46 %. The test-retest reliability of WTP values indices excellent stability and reliability of the instrument with Spearman’s rank correlation coefficient of 0.816 (p<0.001)Conclusion: This study demonstrated that the WTP instrument is feasible and relatively reliable for measuring the WTP values in Indonesia. For wider application of the instrument, its validity should be investigated further. Meanwhile, adoption of WTP as an empirical evidence of societal values is encouraged.

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.

Objective: The aim of this project was to develop the Arabic CAPT (A-CAPT), a Standard Arabic version of the CHEAR auditory perception test (CAPT) that assesses consonant perception ability in children. Method: This closed-set test was evaluated with normal-hearing children aged 5 to 11 years. Development and validation of the speech materials were accomplished in two experimental phases. Twenty-six children participated in phase I, where the test materials were piloted to ensure that the selected words were age appropriate and that the form of Arabic used was familiar to the children. Sixteen children participated in phase II where test–retest reliability, age effects, and critical differences were measured. A computerized implementation was used to present stimuli and collect responses. Children selected one of four response options displayed on a screen for each trial. Results: Two lists of 32 words were developed with two levels of difficulty, easy and hard. Assessment of test–retest reliability for the final version of the lists showed a strong agreement. A within-subject ANOVA showed no significant difference between test and retest sessions. Performance improved with increasing age. Critical difference values were similar to the British English version of the CAPT. Conclusions: The A-CAPT is an appropriate speech perception test for assessing Arabic-speaking children as young as 5 years old. This test can reliably assess consonant perception ability and monitor changes over time or after an intervention.

Background: Undernutrition among schoolchildren is a prevalent public health problem which may be due to inadequate energy and nutrient intakes associated with low dietary diversity. Objective: This study assessed dietary diversity scores (DDS), energy and nutrient intakes of schoolchildren (6-15 years), and risks factors of DDS and determined if energy and nutrient intakes were dependent on dietary diversity. Methods: The study involved a 2-stage random sampling of 90 schoolchildren. Dietary diversity and nutrient intake data were obtained through a 3-day weighed food intake. Analysis of variance, t test, and χ2 with Cochran-Mantel-Haenszel test were used to determine relationships among and between variables; P < .05 was reported as significant. Results: Few (22.2%) had high DDS with no significant difference ( P > .05) between age groups and sex. Children from male headed households were more likely to have medium DDS (odds ratio [OR] = 3.231; 95% confidence interval [CI] = 1.037-10.070) than those from female headed households ( P < .05). Low nutrient intakes were observed among 85.6% for niacin, 76.7% for calcium, 72.2% for riboflavin, 54.4% for protein, 32.2% for thiamine, and 15.6% for vitamin C. Among boys, prevalence of inadequate riboflavin intake was significantly ( P < .05) higher among 6- to 9-year-olds. Among girls, prevalence of inadequate vitamin A intake was significantly ( P < .01) higher among 10 to 15-year-olds. Children with adequate intakes of iron (OR = 0.744, 95% CI = 0.653-0.847) and thiamine (OR = 5.651, 95% CI = 1.214-26.310) were more likely to have high DDS. Conclusion: The schoolchildren had low energy and nutrient intakes. Iron and thiamine, intakes were dependent on DDS.

Abstract Background Physical inactivity is a global phenomenon in European welfare countries. Proper monitoring is essential to measure the physical activity level of the population. Methods In the Hungarian cohort of the European Physical Activity and Sport Monitoring System (EUPASMOS) project, our participants (N = 598) completed sociodemographic questions and the International Physical Activity Questionnaire – short form (IPAQ-SF) survey. The validity and reliability of the subjective measurement tool were examined, IPAQ-SF outcomes were contrasted against triaxial RM42 accelerometer wore for 7 consecutive days. Results The IPAQ-SF showed moderate internal consistency (Cronbach Alpha = 0.647). The concurrent validity of the IPAQ-SF to triaxial accelerometer indicated a significant weak-to-moderate correlation (R = 0.111–0.338, p = 0.042; p < 0.001). The test-retest reliability showed a significant correlation between two measurements (R = 0.788–0.981, p < 0.001). Conclusion The Hungarian version of the IPAQ-SF had excellent test-retest reliability, but low-to-fair concurrent validity for moderate and vigorous physical activity, walking and sitting time, as compared to the objective criterion measure among Hungarian adults.

Abstract BackgroundChildbirth Experience Questionnaire (CEQ) was developed in Sweden to assess the childbirth experience in multiple dimensions. It has been translated and validated in English, Spanish, Chinese and Persian with the aim to evaluate childbirth experience reliably. This study aimed to validate the Finnish version of the questionnaire, CEQ-FI.MethodsPrimiparous women who had given birth in Tampere University Hospital between January and May 2019 were included in the study. Women planning a cesarean delivery, delivering preterm, or women whose children were transferred to neonatal care were excluded. Eligible 450 women were mailed the questionnaire one month postpartum, and those who completed the questionnaire were mailed it again six weeks postpartum. Test-retest reliability was evaluated by computing kappa coefficients for the two responses. Background data was collected from patient records and used to perform known-groups validation. Internal consistency was assessed by calculating Cronbach’s alpha.ResultsOne hundred seventy-five women returned the questionnaire. Internal consistency and test-retest reliability were good. Women with known risk factors for a negative childbirth experience scored lower in the questionnaire, as expected.ConclusionCEQ-FI is a valid and reliable instrument in measuring childbirth experience also among Finnish-speaking women.

ObjectiveThe objective of this study was to validate the computerized Symbol Digit Modalities Test (c-SDMT) in a Swiss pediatric cohort, in comparing the Swiss sample to the Canadian norms. Secondly, we evaluated sex effects, age-effects, and test–retest reliability of the c-SDMT in comparison to values obtained for the paper and pencil version of the Symbol Digit Modalities Test (SDMT).MethodsThis longitudinal observational study was conducted in a single-center setting at the University Children’s Hospital of Bern. Our cohort consisted of 86 children (45 male and 41 female) aged from 8 to 16 years. The cohort included both healthy participants (n = 38) and patients (n = 48) hospitalized for a non-neurological disease. Forty eight participants were assessed during two testing sessions with the SDMT and the c-SDMT.ResultsTest–retest reliability was high in both tests (SDMT: ICC = 0.89, c-SDMT: ICC = 0.90). A reliable change index was calculated for the SDMT (RCIp = −3.18, 14.01) and the c-SDMT (RCIp = −5.45, 1.46) corrected for practice effects. While a significant age effect on information processing speed was observed, no such effect was found for sex. When data on the c-SDMT performance of the Swiss cohort was compared with that from a Canadian cohort, no significant difference was found for the mean time per trial in any age group. Norm values for age groups between 8 and 16 years in the Swiss cohort were established.ConclusionNorms for the c-SDMT between the Swiss and the Canadian cohort were comparable. The c-SDMT is a valid alternative to the SDMT. It is a feasible and easy to administer bedside tool due to high reliability and the lack of motor demands.

Purpose The purpose of this article was to describe the validity and reliability of the Fun and Social Engagement Evaluation (FUSE) developed to evaluate and measure social engagement displayed by nursing home residents during Bingocize. The FUSE combines health care worker observation and a resident self-report measure to produce a score that represents a resident's total engagement. Method To describe validity, trained health care workers who implement Bingocize were surveyed about the items on the FUSE. Visual inspection of bar graphs of responses to survey questions were used to determine content validity. To assess reliability of the FUSE, nursing home residents were evaluated by trained research assistants. Test–retest reliability of the participant scores 1 week apart was determined with the bivariate correlation (Pearson product–moment correlation coefficient). Results For validity, the majority of survey respondents indicated that the behaviors were representative of nursing home residents during Bingocize. For reliability, there was moderate–strong test–retest reliability over 1 week ( r = .60). Interrater reliability between two raters observing eight participants across two sessions was significant, κ = .68 (95% CI [.504,.848]), p < .0001. Conclusion Results offer evidence that the FUSE is a valid and reliable method for determining social engagement during Bingocize.

Test Retest Reliability

The factor structure, the concurrent validity, and test–retest reliability of the Czech translation of the Gifted Rating Scales-School Form [GRS-S; Pfeiffer, S. I., & Jarosewich, T. (2003). GRS (gifted rating scales) - manual. Pearson] were evaluated. Ten alternative models were tested. Four models were found to exhibit acceptable fit and interpretability. The factor structure was comparable for both parent ( n = 277) and teacher raters ( n = 137). High correlations between the factors suggest that raters might be subject to a halo effect. Ratings made by teachers show a closer relationship with criteria (WJ IE II COG, CFT 20-R, and TIM3–5) than ratings made by parents. Test–retest reliability of teacher rating (with median 93 days) was quite high for all GRS-S subscales ( r = .84–.87).
