Tradução e adaptação semântica do Questionário de Controle Atencional para o Contexto Brasileiro

A capacidade de controlar a atenção é uma tarefa complexa que demanda diferentes processos mentais. O presente estudo teve como objetivo traduzir e adaptar o Questionário de Controle Atencional para o Brasil. A pesquisa foi realizada com a ajuda de dois painéis multidisciplinares: um formado por profissionais de Psicologia Experimental e Neurociências responsáveis por auxiliar nas adaptações semânticas, e outro de especialistas em Psicologia da Atenção responsáveis por julgar os itens em três aspectos: clareza, coerência e compatibilidade semântica. O Coeficiente de Validade de Conteúdo foi utilizado para avaliar os itens a partir dos escores desses juízes. Dentre os 20 itens, apenas três não se mantiveram acima do critério de 0,80: itens 3, 16 e 20. Os resultados foram discutidos considerando os problemas enfrentados na adaptação do instrumento. Concluiu-se que o Questionário de Controle Atencional foi traduzido adequadamente e apresenta equivalência semântica com seu original estadunidense.

Stigma in mothers of deaf children.

A deaf child creates a feeling of stigma in many hearing parents. Stigma in mothers can have a negative impact on a child's treatment and rehabilitation process. Therefore, this study was conducted to evaluate the extent of stigma in mothers with deaf children. This descriptive, cross-sectional study was conducted in 2013 among 90 mothers with deaf children. The data-collection instrument included the stigma scale in the mothers of children with disabilities. The reliability and validity of the instrument were confirmed through content validity and Cronbach's alpha coefficient (α=86%), respectively. Data were analyzed using SPSS-15 software. Results showed that most mothers suffer from stigma due to having a deaf child. The mean stigma score was 96.48 ±27.72. In total, 24.4% of mothers reported that they had received strange and mocking looks; 72.2% regarded child deafness as a sign of divine retribution; and 33.3% felt ashamed of their child's deafness. There was an inverse relationship between the mother's level of education and mean stigma scores (P<0.033). The stigma score was higher in mothers who were living independently of their relatives (P<0.029). The mean stigma score in mothers of children with a cochlear implant was lower than that of mothers of children with earphones (86.70 vs. 99.64), and this difference tended towards significance (P=0.057). This study showed that half of all mothers with deaf children were scorned and felt ashamed of having a deaf child in the family because of the stigma. The majority of mothers with deaf children felt stigmatized, and only their education and residency status affected this issue. The mothers of cochlear-implanted children perceived less stigma. Due to the various social and psychological problems caused by hearing impairment, it is necessary to consider the emotional health and psychological state of the mothers in addition to rehabilitation programs and standard services for the children themselves.

Estimación de la Validez de Contenido en una Escala de Valoración del Grado de Violencia de Género Soportado en Adolescentes [Estimate of the Content Validity on a Scale to Assess Gender Violence Rating Supported in Adolescents

This research aims for two achievements; the creation of some tool for the measurement of the domestic violence that teenage girls tolerate and the study of the efficacy of ratings of this instrument. Therefore, we have started from all dimensions that conform the concept of domestic violence: physical, psychological, social and sexual violence. On the other hand, in order to calculate the efficiency of the ratings, we have employed Aiken’s V content validity coefficient, Lawshe’s validity content ratio and Osterlind’s item-objective congruence index. The results let us conclude that such coefficients are suitable to determine this kind of validity, for it offers values which are able to be statistically matched depending on the size of the sample of selected judges. It has also been designed a 21 item instrument with very good content validity values in order to measure the degree of domestic violence tolerated by teenagers.

Tradução e adaptação cultural da Management of Aggression And Violence Attitude Scale – MAVAS – em enfermeiros brasileiros

This study translated and culturally adapted the Management of Aggression and Violence Attitude Scale - MAVAS - for use in Brazil (BR). The methodology followed the international guidelines for the cultural adaptation of psychometric scales: conceptual equivalence, semantic equivalence, items equivalence, and operational equivalence. A group of judges performed a content validity analysis that resulted in a 23-item scale divided into four factors with satisfactory content validity coefficients (CVCs) for the following parameters: clarity of language (CL; 0.88), practical relevance (PR; 0.91), and theoretical relevance (TR; 0.92). The data were collected in Londrina, state of Paraná, BR in 2011. The MAVAS was translated and culturally adapted for use in BR, and the MAVAS-BR exhibited satisfactory content validity. Future studies concerning the MAVAS-BR are suggested, including the evaluation of psychometric qualities, such as its construct validity and reliability.

Comparing the psychometric properties of the pediatric outcomes data collection instrument and the Activities Scales for Kids

The aim of this study was to review and evaluate the psychometric properties of two general musculoskeletal outcome measures focusing on pediatric physical disability, namely, the Pediatric Outcomes Data Collection Instrument (PODCI) and the Activities Scales for Kids (ASK). Although this review reveals the psychometric superiority of ASK to PODCI, further research should confirm the psychometric properties of both the instruments. A number of psychometric issues need to be further addressed. Specifically, future studies should examine additional types of reliability and validity, for example, content, construct, criterion, and discriminant with more sophisticated statistical analyses, for example, Aiken's item content validity coefficient and confirmatory factor analysis. Until these issues are addressed, researchers should be cautious utilizing these instruments in children with musculoskeletal problems in a clinical setting.

Key words: Diabetes; Chinese version of FSFI; Reliability; Validity

Sustainable rangeland management: Pastoralists' attitudes toward integrated programs in Iran

The goal of this survey study was to understand pastoralist attitudes toward sustainable integrated rangeland management (SIRM) in Tehran province, Iran. Using multi-stage stratified random sampling, 1280 pastoralists participated in the study. Data were collected using a researcher-made questionnaire. A panel of experts approved the content validity and Cronbach's alpha coefficient was used to test the reliability of the questionnaire. Results revealed that most of the pastoralists held a positive attitude toward teamwork and collaborative behavior. Moreover, regression analysis indicated that education level, attitudes toward other pastoralists, teamwork and collaboration with administrative officials, significantly affected pastoralist attitudes toward SIRM. Furthermore, path analysis showed that attitudes to other pastoralists indirectly affects attitudes toward SIRM and collaboration with administrative officials. This study concluded that if sustainable rangeland management is a goal, human factors should be considered as a key element.

Sources of stress for nurses in neonatal intensive care units of East azerbaijan province, iran.

Stress is one of the main factors affecting one's efficiency as well as staff health and quality of nursing services. Neonatal intensive care units (NICUs) can be stressful environments for nurses, infants and families as well. Since there is no evidence in this regard in Iran, the present study aimed to determine stress levels related to care delivering in NICU from the viewpoint of nurses in NICUs of East Azerbaijan Province, Iran during 2011. This was a descriptive study including a purposive sample of 110 nurses working in NICUs of hospitals in East Azerbaijan Province. The data collection tool was a self-report questionnaire. The validity and reliability of the questionnaire were assessed by content validity and Cronbach's alpha coefficient (α = 0.84). According to factor analysis, the stressors included environmental and nurse and human factors. Stress sources in total and separately in each category were reported as moderate. The mean and 95% confidence interval of the factors in the categories were 2.75 (0.84); 2.59-2.91 and 3.21 (0.72); 3.07-3.35, respectively. Therefore, human factors caused significantly higher levels of stress compared to environmental factors (p < 0.05). Stressors involved in NICU nursing include environmental and human factors. Planning to remove or reduce their impact can improve the quality of nursing services in intensive care units and, thus, decrease the adverse effects of stress on workers.

Patient Satisfaction With Anesthesia Care in Taiwan: Development and Validation of a Pilot Version of a Psychometric Questionnaire

To date, no pilot questionnaire of perioperative anesthetic care has been developed based on psychometric methodology in Taiwan. We describe the development and qualitative and quantitative validation of a pilot version of a psychometric questionnaire designed to measure patient satisfaction with perioperative anesthetic care in Taiwan. A rigorous protocol was followed and involved expert consultation, literature review, development of the interview guide, semi-structured in-depth interviews, pretest and application of Aiken's two quantitative methods to determine the content validity coefficient (V value) and homogeneity reliability coefficient (H value) of each item, and the questionnaire as a whole, to ensure the pilot questionnaire showed high-content validity and reliable homogeneity. Our final pilot questionnaire contained six dimensions with 32 items; five of the domains were similar to those reported in the literature. One dimension entitled anesthesia-related sequelae was new. The V values for the 32 items ranged from 0.80 to 0.97 (p < 0.01) and the mean value (V) of the questionnaire as a whole was 0.90 (p < 0.01). The H values ranged from 0.55 to 0.88 (p < 0.01) and the mean H value (H) of the questionnaire as a whole was 0.71 (p < 0.01). We have developed a valid and reliable pilot questionnaire to measure patient satisfaction with perioperative anesthetic care in Taiwan. The final version of the pilot questionnaire is a 32-item instrument with six dimensions, one of which, anesthesia-related sequelae, is new.

HOW VALID ARE SCHOOL EXAMINATIONS? AN EXPLORATION INTO CONTENT VALIDITY

Summary. It is generally accepted that quantification of content validity is not possible. In this paper, a proposal is made by which a content validity coefficient, Ccv can be calculated. An example of the use of the coefficient is given, demonstrating that different question combinations in a CSE biology examination in which a choice of questions was given gave different levels of content validity. The coefficient was used to demonstrate that deficiencies in validity in the examination are due more often to inadequate sampling of the educational objectives which the examination might be expected to test rather than to inadequate sampling of the subject matter.

Content Validity and Reliability of Single Items or Questionnaires

Procedures for computing content validity ( V) and consistency re liability ( R) coefficients and determining the statistical significance of these coefficients are described. These procedures, which employ the multinomial probability distribution for small samples and nor mal curve probability estimates for large samples, can be used in a variety of situations where judgments of the content validity of items or questionnaires are made on ordinal rating scales. Computing for mulas for determining the statistical significance of V and R for large samples of raters and any number of rating categories are given. A computer program has been written to determine the right- tail probabilities associated with values of V and R obtained from ratings by N raters using c rating categories.

Ravens Progressive Matrices (1938): normative data on male narcotic addicts.

The Ravens Progressive Matrices (RPM), a test of intellectual ability, was administered to 396 male narcotic users. Norms are given, and concepts basic to the validity and reliability of the RPM tested. Significant shifts were found in item order in sets A, B, C, and D. Differences were not considered crucial for each set, which was progressively more difficult than the preceding set; thus the total structure of the test was supported by the sample. The discriminative power of most items ranged from good to excellent. In investigating properties of distractors, answer four was chosen significantly more often than other alternatives as the wrong answer in sets C, D and E identifying the possible operation of a positional distractor. Test-retest reliability, content and concurrent validity coefficients were of the order of .8. Correlation of formal education with RPM was of the order of .2. Previously available normative data on patient samples ae extended and use of the RPM as a measure of intellectual performance relatively free from language and cultural bias is supported.
