Review
A child's diet is an important determinant of growth and development. Because of this, the accurate assessment of dietary intake in young children remains a challenge. A systematic search of studies validating FFQ methodologies in children 12 to 36 months of age was completed. English-language articles published until March 2016 were searched using three electronic databases (MEDLINE, EMBASE and CINAHL). Quality assessment of the identified studies was carried out using The Reduced Summary Score and EURopean micronutrient RECommendations Aligned (EURRECA) scoring system. Seventeen studies were included and categorised according to whether they reflected long-term (≥7 d) or short-term (<7 d) intake, or used a biomarker. A total score for each micronutrient was calculated from the mean of the correlation coefficients weighted by the study quality score. At least three validation studies per micronutrient were required for inclusion. Fifteen studies (83 %) that considered validity of the FFQ in assessing nutrient intakes had quality scores from 2·5 to 6·0. Of those, ten (67 %) studies found FFQ to have good correlations in assessing dietary intake (>0·4). Of the nutrients with three or more studies available, FFQ validated using a reference method reflecting short-term intake had a good weighted correlation for Ca (0·51), and acceptable weighted correlations for vitamin C (0·31) and Fe (0·33). Semi-quantitative FFQ were shown to be valid and reproducible when estimating dietary intakes at a group level, and are an acceptable instruments for estimating intakes of Ca, vitamin C and Fe in children 12 to 36 months of age.

BACKGROUND
Visual vertigo (VV), triggered by environmental or dynamic visual stimuli and repetitive visual patterns, can affect daily life activities. The Visual Vertigo Analogue Scale (VVAS) is a valid and reliable self-administered questionnaire to assess VV, which has been culturally adapted to the Argentine population but has not been validated.
OBJECTIVE
To validate the Argentine version of VVAS (VVAS-A) by confirming its psychometric properties in patients with vestibular disorders.
METHODS
Vestibular patients (n = 82) completed the VVAS-A and the Dizziness Handicap Inventory Argentine version (DHI-A) during their initial visit and one week later. The VVAS-A's internal consistency, test retest reliability, ceiling and floor effects, and construct validity were determined. Test-retest data (n = 71) was used to calculate reliability using the intraclass correlation coefficient (ICC 2.1).
RESULTS
A ceiling effect was observed in 12 patients (14.6%). Internal consistency was acceptable (Cronbach's alpha: 0.91). The reliability was r = 0.764 [CI 95%: 0.7 -0.86]). Correlations were observed between the VVAS-A and the total DHI-A score (rho = 0.571), the DHI-A physical subscale (rho: 0.578), and DHI-A functional and emotional subscales of the DHI-A (rho: 0.537 and 0.387, respectively).
CONCLUSION
The VVA-A is a valid, reliable tool to evaluate VV in patients with vestibular disorders.

The psychometric properties of a 14-item bidimensional Mathematics Anxiety Scale-Revised (MAS-R) were empirically cross-validated with two independent samples consisting of 647 secondary school students. An exploratory factor analysis on the scale yielded strong construct validity with a clear two-factor structure. The results from a confirmatory factor analysis indicated an excellent model-fit (χ(2) = 98.32, df = 62; normed fit index = .92, comparative fit index = .97; root mean square error of approximation = .04). The internal consistency (.85), test-retest reliability (.71), interfactor correlation (.26, p < .001), and positive discrimination power indicated that MAS-R is a psychometrically reliable and valid instrument for measuring mathematics anxiety. Math anxiety, as measured by MAS-R, correlated negatively with student achievement scores (r = -.38), suggesting that MAS-R may be a useful tool for classroom teachers and other educational personnel tasked with identifying students at risk of reduced math achievement because of anxiety.

Journal of Attention Disorders Dec 2022The current study aimed to validate the utility of previously established validity indicators derived from MOXO-d-CPT's continuous performance test.
BACKGROUND
The current study aimed to validate the utility of previously established validity indicators derived from MOXO-d-CPT's continuous performance test.
METHOD
Healthy simulators feigned impairment after searching online for relevant information, an ecologically valid coaching condition ( = 39). They were compared to ADHD patients ( = 36) and healthy controls ( = 38).
RESULTS
Simulators performed significantly worse than ADHD patients in all MOXO-d-CPT indices, as well as a scale that integrates their contributions (feigned ADHD scale). Three indices (attention, hyperactivity, and impulsivity) and the latter scale exhibited adequate discriminative capacity. Higher education was associated with an exaggerated impairment among simulators, easing their detection.
CONCLUSION
Similarity between the current study and a previous study which examned the utlity of the MOXO-d-CPT validity indicators, increases our confidence in the efficacy of the latters embedded validity indicators. Though the findings provide initial validation of these validity indicators, generalizing beyond highly functioning participants necessitates further research.

Ambulatory care sensitive conditions (ACSC) can be avoided through effective care in the ambulatory setting. Patients are the most qualified individuals to express the social and individual contexts of their own experience. Thus, understanding why potentially preventable hospitalizations occur is important to develop patient-centred policies or interventions that may reduce them. This study aims to develop and validate a questionnaire to capture the patients' perspective on the causes of the hospitalizations for ACSC. The development of a new questionnaire involved four phases: a literature review, face validity, pre-test, and validation. We conducted a three-step face validity verification to confirm the relevance of the identified determinants and to collect determinants not previously identified by interviewing healthcare providers, representatives of patients' associations, and patients. Determinants were identified through the literature review predominantly in the "Healthcare Access", "Disease self-management", and "Social Support" domains. The validated resulting questionnaire comprises 25 questions, distributed by two dimensions (individual/contextual) covering seven domains and 20 determinants of ACSC hospitalization. Currently, there are no validated instruments as comprehensive and easy to use as the one described in this paper. This questionnaire should provide a base for further language/context validations.

We have attempted to reproduce a biologically-constrained point-neuron model of CA1 pyramidal cells. The original models, developed for the Brian simulator, captured the frequency-current profiles of both strongly and weakly adapting cells. As part of the present study, we reproduced the model for different simulators, namely Brian2 and NEURON. The reproductions were attempted independent of the original Brian implementation, relying solely on the published article. The different implementations were quantitatively validated, to evaluate how well they mirror the original model. Additional tests were developed and packaged into a test suite, that helped further characterize and compare various aspects of these models, beyond the scope of the original study. Overall, we were able to reproduce the core features of the model, but observed certain unaccountable discrepancies. We demonstrate an approach for undertaking these evaluations, using the SciUnit framework, that allows for such quantitative validations of scientific models, to verify their accurate replication and/or reproductions. All resources employed and developed in our study have been publicly shared the EBRAINS Live Papers platform.

Revista Brasileira de Enfermagem 2022To construct and validate three clinical scenarios for training dependent persons' informal caregivers.
OBJECTIVE
To construct and validate three clinical scenarios for training dependent persons' informal caregivers.
METHODS
Methodological study, conducted between January and August 2021, in a municipality in the northwest of the state of Paraná. It was developed in two stages: construction of scenarios; and content validation by experts (n = 12). To estimate the degree of agreement between the experts, the content validity index was used, and 80% was considered an acceptable rate of agreement.
RESULTS
The simulation scenarios proved appropriate, obtaining an average value of 91.6%. However, some adjustments were made in their organization pertaining clarity in the wording of guidelines, as suggested by the expert validators.
CONCLUSIONS
The construction and validation of the clinical scenarios proved to be adequate and relevant for use in the training of informal caregivers of dependent persons.

A long-established approach, Confirmatory Factor Analysis (CFA) is used to validate measurement models of latent constructs. Employing CFA can be useful for assessing the validity and reliability of such models. The study adapted previous instruments and modified them to suit the current setting. The new measurement model is termed NENA-q. Exploratory factor analysis (EFA) revealed the instruments of the NENA-q model formed a construct of the second order with four dimensions, namely organizational contribution (OC), academic institution contribution (AIC), personality traits (PT), and newly employed nurses' adaptation (NENA). Researchers administered the questionnaires to a sample of 496 newly employed nurses working in hospitals under the Ministry of Health (MOH) for the confirmation of the extracted dimensions. The study performed a two-step CFA procedure to validate NENA-q since the model involves higher-order constructs. The first step was individual CFA, while the second step was pooled CFA. The validation procedure through confirmatory factor analysis (CFA) found the model achieved the threshold of construct validity through fitness index assessment. The model also achieved convergent validity when all average variance extracted (AVE) exceeded the threshold value of greater than 0.5. The assessment of the composite reliability (CR) value indicates all CR values exceeded the threshold value of 0.6, which indicates the construct achieved composite reliability. Overall, the NENA-q model consisting of the OC construct, AIC construct, PT construct, and NENA construct for CFA has met the fitness indexes and passed the measurements of the AVE, CR, and normality test. Once the measurement models have been validated through CFA procedure, the researcher can assemble these constructs into structural model and estimate the required parameter through structural equation modelling (SEM) procedure.

Cyberbullying is a global and growing phenomenon, which affects the wellbeing of millions of adolescents around the world including Chinese adolescents. However, there is a lack of valid and reliable measures of cyberbullying behaviours in Chinese. To address this research gap, this study aims to adapt and validate a well-known, reliable and validated instrument: the European Cyberbullying Intervention Project Questionnaire (ECIPQ) among Chinese adolescents. A 14-item (seven for cyber aggression and seven for cyber victimisation) of the Chinese version of ECIPQ was developed based on its relevance and appropriateness to the Chinese culture. After its cultural and linguistic adaptation, the measure was norm with a sample of Chinese adolescents. A total sample of 452 adolescents was randomly split into two evenly subsamples for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The EFA results indicated that the Chinese version of ECIPQ had a good convergent validity and satisfactory discriminant validity, and a two-factor model was identified. CFA results showed a good fit of the measurement model in assessing cyber aggression and cyber victimisation. This adapted Chinese version of ECIPQ can be used to facilitate future research on cyberbullying screening, and that research may in turn promote proactive screening and better coordination of community responses for victims as well as perpetrators. Future comparative studies may use the validated scale to assess the prevalence of cyberbullying and the results of interventions to reduce cyberbullying among Chinese adolescents.
