Estimation of the predictive power of the model in mixed‐effects meta‐regression: A simulation study
José Antonio López‐López Fulgencio Marín‐Martínez Julio Sánchez‐Meca Wim Van den Noortgate Wolfgang Viechtbauer 《The British journal of mathematical and statistical psychology》2014,67(1):30-48
Several methods are available to estimate the total and residual amount of heterogeneity in meta‐analysis, leading to different alternatives when estimating the predictive power in mixed‐effects meta‐regression models using the formula proposed by Raudenbush (1994, 2009). In this paper, a simulation study was conducted to compare the performance of seven estimators of these parameters under various realistic scenarios in psychology and related fields. Our results suggest that the number of studies (k) exerts the most important influence on the accuracy of the results, and that precise estimates of the heterogeneity variances and the model predictive power can only be expected with at least 20 and 40 studies, respectively. Increases in the average within‐study sample size () also improved the results for all estimators. Some differences among the accuracy of the estimators were observed, especially under adverse (small k and ) conditions, while the results for the different methods tended to convergence for more optimal scenarios. 相似文献

In order to explore the role of the main psycholinguistic variables on visual word recognition, several mega-studies have been conducted in English in recent years. Nevertheless, because the effects of these variables depend on the regularity of the orthographic system, studies must also be done in other languages with different characteristics. The goal of this work was to conduct a lexical decision study in Spanish, a language with a shallow orthography and a high number of words. The influence of psycholinguistic variables on latencies corresponding to 2,765 words was assessed by means of linear mixed-effects modeling. The results show that some variables, such as frequency or age of acquisition, have significant effects on reaction times regardless of the type of words used. Other variables, such as orthographic neighborhood or imageability, were significant only in specific groups of words. Our results highlight the importance of taking into account the peculiarities of each spelling system in the development of reading models. 相似文献

This study analyzes the differences in job satisfaction of older European people (aged 50-64), with or without disabilities, who are employed in either the public or the private sector. Using the data taken from the Survey of Health, Ageing and Retirement in Europe (SHARE) for the years 2004, 2007 and 2011, job satisfaction equations are estimated for workers from both the public and private sectors, with panel data techniques that include variables related to the worker's degree of disability (nondisabled, non-limited disabled, and limited disabled), among others. The results show that the disabled workers who are limited in their everyday activities are less satisfied in both the public and private sectors than those who are non-disabled and non-limited. In addition, the levels of job satisfaction for non-limited disabled people are higher than their non-disabled counterparts but only in the public sector. From a point of view of public policies, it is necessary to design and undertake measures and actions that would contribute to improving the levels of job satisfaction of older workers with disabilities, especially among those who are limited in their everyday activities. 相似文献

Academic self-handicapping is a very popular subject of research in educational psychology, in which a growing number of related findings are reported. However, apart from a recent meta-analysis (Schwinger et al. in J Educ Psychol 106(3):744–761, 2014), the last comprehensive review of the subject was published 17 years ago (Urdan and Midgley in Educ Psychol Rev 13(2):115–138, 2001). This paper integrates relevant findings accumulated since then, which are discussed in a coherent interpretive framework. The first part of the paper discusses the definition and theoretical grounds of academic self-handicapping, then its manifestations in an academic context are enumerated. The second part of the study focuses on the self-protective function of stereotypes based on self-handicapping as well as on the impressions self-handicapping students may make on others at school. A summary of the contributions of goal orientation theory is provided in relation to self-handicapping, and the effects of various goal orientations and goal structures on academic performance are analysed. Based on an analysis of interactions between self-handicapping and academic performance, the authors argue for the importance of prevention and suggest possible ways to prevent self-handicapping. In conclusion, measurement issues of academic self-handicapping and the methodological paradox inherent in questionnaire measures are discussed. 相似文献
