DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n6p629 Declarative Tactical Knowledge Tests are presented as important evaluation tools for the teaching-learning-training process regulation. This study aimed to establish the content validity of scenes of the Declarative Tactical Knowledge Test in Volleyball – DTKT:Vb. Five male coaches of the Brazilian Volleyball team who worked with male athletes participated as judges, being responsible for training formation categories up to 21 years, experts in the sport, with minimum ten years of experience. The judges evaluated 212 scenes containing extremity attack (n=55), central attack (n=33), setting (n=68) and block (n=60) situations and used a 1-5 point likert scale to assign a score to the scene according to requisites image clarity, practical relevance and item representativity. The Content Validity Coefficient (CVC) was used to determine the CVC for each scene and the instrument as a whole, with cutoff point of 0.80. The results demonstrated that “image clarity” (CVC=0.92), “practical relevance” (CVC=0.96) and “item representativity” criteria (CVC=0.96) showed satisfactory levels. After calculating CVC, the ecological validity of scenes was determined, which consists of the selection of scenes where there was convergence among decision made by judges and decision made by athletes. Thus, from 212 scenes initially prepared, 66 have been validated. Scenes validated using CVC enabled the evaluation of the Declarative Tactical Knowledge, assisting in the planning of teaching-learning-training processes of male volleyball athletes.

The validation of this questionnaire is an important tool for analyzing the knowledge and skills of coaches, as well as a better understanding of their practice context. Therefore, the aim of the present study was to establish the content validity of the Coaches’ Knowledge and Competence Questionnaire (CKCQ). Five specialists with doctorate degree for at least 10 years, academic experience and periodicity of publications with the theme in national and international journals participated in the validation process. Specialists evaluated 38 items of the questionnaire and assigned a score on a 1-5 point likert scale for each item in the language clarity, practical pertinence and theoretical relevance criteria. The content validity coefficient (CVC) was used to determine the CVCI of items and the CVCt of the total instrument of each criterion, adopting cutoff point of 0.81. The approximate results found for language clarity (0.92), practical pertinence (0.99) and theoretical relevance (0.98) presented values considered almost perfect and appropriate for validation. The content validation of the CKCQ is an important alternative for the evaluation of the knowledge and competences of sports coaches.

Objective To develop and validate the content of an instrument for assessing the motivation for weight loss in adolescents with overweight and obesity. Methods The development and validation of the instrument were conducted in five stages, for which two systematic reviews were conducted. The first one, for the identification of questionnaires assessing the motivation for weight loss, included six studies and contributed to the selection of the domains for the instrument. The second one, conducted to identify the motivations for weight loss in adolescents with overweight and/or obesity, included six studies and contributed to the selection of 17 motivations included in the initial version of the instrument. The motivations most commonly identified were: having better health, improving my appearance, improving my self-esteem and avoiding bullying. The content validity was confirmed by a committee of 12 experts from the areas of nutrition, endocrinology, psychology, and physical education. Based on these evaluations, the content validity index was calculated. Only the items with a content validity index >0.80 for practical relevance were held in the instrument. Results Five of the 17 motivations included in the initial version of the instrument were excluded because they had content validity index <0.80 for practical relevance. Of the 12 items held in the instrument, five were revised by experts in order to standardize wording and make the language more appropriate for adolescents. Experts categorized the items into the health, personal satisfaction, appearance and social domains. Conclusions This is the first instrument assessing the motivation for weight loss in adolescents with overweight and obesity in Brazil. The content validity evaluation by the panel of experts provided more practical relevance, as well as contributed to a better presentation of the items. Further psychometric testing is needed to determine reliability and construct validity of the instrument.

Abstract The main objective of this study was to establish content validity evidences in the Motor Coordination Test with Ball (MCTB). Four Ph.D. professors and former sports coaches with academic experience in the motor coordination area took part of the validation process as experts. The experts assessed four motor tasks and graded using the Likert scale from one to five for criteria of clarity of language, practice relevance, and theoretical relevance. The content validity coefficient (CVC) has been used to determine the CVCc of each task and the CVCt for the instrument as a whole, adopting as a cutoff CVCc .70 and CVCt .80. The results showed good agreement among experts concerning “clarity of language” (CVC= .89), “practice relevance” (CVC= .81), and theoretical relevance (CVC= .86). For “practice relevance” of images and videos of task execution, there has been observed CVCt of .86 and CVCt of .95, respectively. When requested the order of relevance of coordination pressures, the agreement among experts presented the existence of at least four coordination pressures in each one of the tasks and, out of these, at least two had a higher relevance. After the calculation of the CVC, ecological validity was determined for the MCTB, accrediting it as an instrument for the assessment of motor coordination with ball in the context of sports games.

The purpose of this paper was to adapt and validate the Sport-Multidimensional Perfectionism Scale-2 (SMPS-2) for the Brazilian population using a three-step approach. For content validity, four participants translated the SMPS-2 to Portuguese and six experts adapted the content. Construct validity sample was tested with 395 athletes from a set of individual and team sports. Temporal validity was evaluated with an independent sample of 80 athletes with two data collections. Data analysis was conducted through Content Validity Coefficient (CVC), Cronbach's alpha, Composite Reliability (CR) and Exploratory (EFA) and Confirmatory (CFA) analyses. Results showed that the Portuguese version contained clear and relevant questions (CVC > .80) and good internal consistency (α > .70/CR > .70); EFA model revealed a four factor solution with 24 items as more satisfying while CFA confirmed the SMPS-2 model with 24 items was adequate. Multi-group analysis showed partial gender invariance. Temporal stability was achieved in all 24 items of the scale (ICC > .75). We concluded that the SMPS-2 is a valid measure for the assessment of perfectionism of the Brazilian sport context.

Neuroimaging and neuropsychological methods have contributed much toward an understanding of the information processing systems of the human brain in the last few decades, but to what extent do cognitive neuroscientific findings represent and generalize to the inter- and intra-brain dynamics engaged in adapting to naturalistic situations? If it is not marked, and experimental designs lack ecological validity, then this stands to potentially impact the practical applications of a paradigm. In no other domain is this more important to acknowledge than in human clinical neuroimaging research, wherein reduced ecological validity could mean a loss in clinical utility. One way to improve the generalizability and representativeness of findings is to adopt a more “real-world” approach to the development and selection of experimental designs and neuroimaging techniques to investigate the clinically-relevant phenomena of interest. For example, some relatively recent developments to neuroimaging techniques such as functional near-infrared spectroscopy (fNIRS) make it possible to create experimental designs using naturalistic tasks that would otherwise not be possible within the confines of a conventional laboratory. Mental health, cognitive interventions, and the present challenges to investigating the brain during treatment are discussed, as well as how the ecological use of fNIRS might be helpful in bridging the explanatory gaps to understanding the cultivation of mental health.

La Radio Cognitiva (CR) es el paradigma que permite optimizar la eficiencia del espectro radio eléctrico a través de una gestión dinámica basado en el sensado, decisión, compartición y movilidad espectral, siendo la toma de decisiones la encargada de la selección del mejor/mejores canales para la transmisión de los datos de los nodos cognitivos (SUs), dependiendo de la calidad de servicio solicitada (Best Effort (BE) o Real Time (RT)). La literatura existente plantea implícitamente la utilización de una estrategia reactiva para la selección de dichas bandas; no obstante, ello implica que las solicitudes de los SUs solo se procesarán una vez arriben a la estación base (BS) de la red cognitiva, generando retrasos adicionales en el envío de los datos. En el presente artículo se plantea el uso de la estrategía proactiva planteada en [1], pretendiendo con ello que el procesamiento de las solicitudes de asignación de espectro para los SUs se realice de manera más rápida o eficiente (tiempo menor de procesamiento en la estación base (BS)), con ello optimizando la etapa de decisión espectral en CR.  Los resultados demuestran que el sistema proactivo reduce el tiempo de asignación de canales a los SUs sin degradar la comunicación del PU.

This research is part of the standardization of the Students' Coping Strategy Scale (SCSS). This study aims to reveal the content validity, empirical validity, and reliability of the SCSS. The non-test instrument consisting of 42 statements from three dimensions: problem-focused coping, emotion-focused coping, and seeking social support. Content validity analysis was carried out by experts to obtain Gregory's content validity coefficient, while the empirical validity and reliability analysis by empirically testing the instrument on 211 respondents and analyzed using the Rasch model approach. The results show that Gregory's content validity coefficient is 0.714, so it needs improvement on some items that are considered unsuitable. Empirical validity analysis using WINSTEPS software shows that three items do not fit the model. The reliability coefficient of the SCSS is 0.99. Thus, the remaining 39 items are appropriate to be used to measure students' coping strategies.
