Abstract

Establishing stability, defined as observing minimal measurement error in a test-retest assessment, is vital to validating psychometric tools. Correlational methods, such as Pearson product-moment, intraclass, and kappa are tests of association or consistency, whereas stability or reproducibility (regarded here as synonymous) assesses the agreement between test-retest scores. Indexes of reproducibility using the Task and Ego Orientation in Sport Questionnaire (TEOSQ; Duda & Nicholls, 1992) were investigated using correlational (Pearson product-moment, intraclass, and kappa) methods, repeated measures multivariate analysis of variance, and calculating the proportion of agreement within a referent value of +1 as suggested by Nevill, Lane, Kilgour, Bowes, and Whyte (2001). Two hundred thirteen soccer players completed the TEOSQ on two occasions, 1 week apart. Correlation analyses indicated a stronger test-retest correlation for the Ego subscale than the Task subscale. Multivariate analysis of variance indicated stability for ego items but with significant increases in four task items. The proportion of test-retest agreement scores indicated that all ego items reported relatively poor stability statistics with test-retest scores within a range of +1, ranging from 82.7–86.9%. By contrast, all task items showed test-retest difference scores ranging from 92.5–99%, although further analysis indicated that four task subscale items increased significantly. Findings illustrated that correlational methods (Pearson product-moment, intraclass, and kappa) are influenced by the range in scores, and calculating the proportion of agreement of test-retest differences with a referent value of +1 could provide additional insight into the stability of the questionnaire. It is suggested that the item-by-item proportion of agreement method proposed by Nevill et al. (2001) should be used to supplement existing methods and could be especially helpful in identifying rogue items in the initial stages of psychometric questionnaire validation.  相似文献

Research Findings: The Early Education Essentials surveys use teacher and parent perceptions to measure 6 organizational conditions of early childhood education programs, extending and complementing existing measures of early childhood care and education (ECE) quality constructs. This study tests the reliability and concurrent validity of the Early Education Essentials in 81 school- and community-based ECE sites in a large Midwestern city selected using a stratified random sampling method. Using a Rasch item response theory model, scales were created; theory and exploratory factor analyses combined scales into higher level constructs called essentials. Multilevel models took into account individual measurement error to create site-level essential scores and assessed relationships between programs’ essential scores and site-level teacher–child interactions scores and student attendance. Findings suggest that the Early Education Essentials is reliable in multiple ECE settings; it is sensitive to site-level differences; and some, but not all, organizational conditions measured are associated in expected directions with site-level metrics indicative of center-based ECE quality. Practice or Policy: The Early Education Essentials has the potential to provide leaders and practitioners with actionable data about organizational supports that enable ECE practitioners to be more effective in their daily work with children and families.  相似文献

Research Findings: An empirical investigation was conducted to test young Palestinian, Jordanian, Israeli-Palestinian, and Israeli-Jewish children's (N = 433; M = 5.7 years of age) cultural stereotypes and their evaluations of peer intergroup exclusion based upon a number of different factors, including being from a different country and speaking a different language. Children in this study lived in a geographical region that has a history of cultural and religious tension, violence, and extreme intergroup conflict. Our findings reveal that the negative consequences of living with intergroup tension are related to the use of stereotypes. At the same time, the results for moral judgments and evaluations about excluding peers provide positive results about the young children's inclusive views regarding peer interactions. Practice: These findings indicate that practitioners working with young children should focus on inclusion in peer contexts. Curricula, media, and social intervention programs must begin in early childhood before children begin to use stereotypes in peer situations, particularly when children from other cultural and ethnic backgrounds play together.  相似文献

We provide a systematic review of the literature on academic engagement from 2011 onwards, which was the cut-off year of a previous review article published in Research Policy. Academic engagement refers to knowledge-related interactions of academic scientists with external organisations. It includes activities such as collaborative research with industry, contract research, consulting and informal ties. We consolidate what is known about the individual, organisational and institutional antecedents of academic engagement, and its consequences for research, commercialisation, and society at large. Our results suggest that individual characteristics associated with academic engagement include being scientifically productive, senior, male, locally trained, and commercially experienced. Academic engagement is also socially conditioned by peer effects and disciplinary characteristics. In terms of consequences, academic engagement is positively associated with academics’ subsequent scientific productivity. We propose new areas of investigation where evidence remains inconclusive, including individual life cycle effects, the role of organisational contexts and incentives, cross-national comparisons, and the impact of academic engagement on the quality of subsequent research as well as the educational, commercial and society-wide impact.  相似文献

The purpose of this study was to examine age and competitive level differences in the relationship between determinants and level of sport commitment. Gymnasts (N = 304) comprised three age groups (8-11, 11-14.5, and 14.5-18 years) and two competitive levels (Levels 5-6 and 8-10). Multiple regression analyses revealed: (a) perceived costs and social constraints from parents and best friends were the strongest predictors of commitment for the youngest gymnasts, (b) perceived costs, personal investments, and parent social constraints predicted commitment for 11-14.5-year-old gymnasts, and (c) perceived competence and costs predicted commitment for the oldest gymnasts. Competitive level differences also emerged; for Level 5-6 gymnasts, personal investments, perceived costs, coach social support, and social constraints by coach, best friend, and teammates were predictors of commitment. Personal investments and teammate social constraints were significant predictors for Level 8-10 gymnasts. Developmental factors and additional determinants are important to consider in further studies of the sport commitment model.  相似文献

This study examined the relative contributions of phonological awareness, orthographic pattern recognition, and rapid letter naming to fluent word and connected-text reading within a dyslexic sample of 123 children in second and third grades. Participants were assessed on a variety of fluency measures and reading subskills. Correlations and hierarchical multiple regression analyses were carried out to explore these relationships. The results demonstrate that phonological awareness, rapid letter naming, and orthographic pattern recognition contribute to word-reading skills. Furthermore, rapid naming, orthographic pattern recognition, and word reading fluency moderately predict different dimensions of connected-text reading (i.e., rate, accuracy, and comprehension) whereas phonological awareness contributes only to the comprehension dimension of connected-text reading. The findings support the multidimensional nature of fluency in which the whole is more than its parts.  相似文献
