编制运动员社会支持量表（SSQA），检验其信效度和科学性，实现社会支持的定量化评定，为运动员成长成才所需社会支持提供科学依据。运用量表编制的理论与方法形成运动员社会支持预调研量表，对460名运动员实施预调研。通过探索性因素分析形成正式测试量表，对1 056名运动员实施调研，采用验证性因素分析和信效度检验形成正式量表。结果：SSQA包含24个题项，分属教练支持、家庭支持、同伴支持、组织支持、政策舆论支持5个维度，累积解释变异量为68.419%；验证性因素分析表明量表拟合指数理想；SSQA内部一致性系数达0.908，重测系数为0.843，各维度Cronbach α系数和重测系数均达0.7以上；SSQA与效标量表相关系数为0.478，每个题项在各自维度中的负荷量均接近或大于0.6，在其他维度中的负荷量皆小于0.4。验证表明：SSQA具有良好的信度和效度，可以作为运动员社会支持测量的规范量表。  相似文献   

Snap-N-Send: A valid and reliable method for assessing the energy intake of elite adolescent athletes

To ensure that elite adolescent athletes meet their unique training, growth and maturation demands, it is imperative to have access to valid measures of energy intake. Contemporary methods demand close attention-to-detail, meaning that athletes often do not fully adhere to real-time protocols. This study represents the first investigation of a real-time dietary assessment designed using a comprehensive behaviour change framework (COM-B). In a crossover design, 12 elite adolescent male rugby players recorded their energy intake via an estimated food diary (est-FD) and photography-based mobile assessment (‘Snap-n-Send’), combined with a 24-h dietary recall interview. Two 4-day assessment periods were divided into three separate recording environments: 96?h free-living and researcher-observed; 72?h free-living and 10?h researcher-observed. Assessment periods were one month apart. All foods and beverages were provided and weighed by the research team to quantify actual intakes. ‘Snap-n-Send’ reported a small mean bias for under-reporting across 96?h (?0.75?MJ?day^?1; 95% confidence interval [CI] for bias?=??5.7% to ?2.2%, p?<?.001), 72?h (?0.76?MJ?day^?1; 95% CI for bias?=??5.6% to ?2.1%, p?=?.004) and 10?h (?0.72?MJ?day^?1; 95% CI for bias?=??8.1% to ?0.1%; p?=?.067) environments. The est-FD reported a moderate mean bias for under-reporting across 96?h (?2.89?MJ?day^?1; 95% CI for bias?=??17.9% to ?10.2%; p?<?.001), 72?h (?2.88?MJ?day^?1; 95% CI for bias?=??17.9% to ?10.1%; p?<?.001) and 10?h (?2.52?MJ?day^?1;?26.1% to ?5.3%; p?=?.023) environments. Results evidence the ability of ‘Snap-n-Send’ to accurately assess the diet of elite adolescent athletes, signalling the exciting promise of this comprehensive and theoretical behavioural approach within valid dietary assessment.  相似文献   

Measuring preservice teacher self-efficacy in music and visual arts: Validation of an amended science teacher efficacy belief instrument     

《Teaching and Teacher Education》2017

The Science Teacher Efficacy Belief Instrument has been a widely reported measure of teachers' personal efficacy and outcome efficacy beliefs. This pilot study examined if the instrument could be amended for use in The Arts learning area. A small cohort of 110 Graduate Diploma of Education preservice teachers participated in the pilot. Factor structures were examined through confirmatory factor analyses. The model displaying best fit consisted of six items measuring outcome expectancy and 10 items related to teaching efficacy. Measuring self-efficacy is important as many teachers who teach the Arts in Australia and internationally are not subject specialist teachers.  相似文献   

There Is More to Educational Measurement Than Measuring: The Importance of Embracing Purpose Pluralism          下载免费PDF全文

Paul E. Newton 《Educational Measurement》2017,36(2):5-15

The dominant narrative for assessment design seems to reflect a strong, albeit largely implicit undercurrent of purpose purism, which idealizes the principle that assessment design should be driven by a single assessment purpose. With a particular focus on achievement assessments, the present article questions the tenability of purpose purism, explaining how critical decisions—concerning whether to assess, how to specify an assessment construct, and many other design characteristics—require the coordination of multiple perspectives on assessment purposes. It argues the case for purpose pluralism—which idealizes the principle that assessment design should be driven by a multiplicity of assessment purposes simultaneously—not as an occasional, unavoidable concession, but as an organizing principle. The point of explicitly distinguishing between perspectives is to help assessment designers to establish a full complement of design requirements, representing a full range of stakeholder voices; as well as to manage more effectively the trade‐offs and compromises that inevitably arise.  相似文献

How specific is specific self-efficacy? A construct validity study using Rasch measurement models     

《Studies in Educational Evaluation》2017

Self-efficacy is an important and much used construct in psychology and social science studies. The validity of the measurements used is not always sufficiently evaluated. The aim was to evaluate the psychometric properties of the Danish translation of the self-efficacy subscale of The Motivated Strategies for Learning Questionnaire (MSLQ-SE) within a higher education context. Rasch measurement models were employed focusing on measurement invariance and dimensionality. Results with one students sample showed the MSLQ-SE to be not one, but two separate unidimensional subscales, measuring specific academic learning self-efficacy (SAL-SE) and specific academic exam self-efficacy (SAE-SE), each scale being measurement invariant relative to age, Gender, admission method and specific course targeted. Furthermore, significant and relevant differences between the SAL-SE and SAE-SE scores dependent on university and admission method were found, and these results were replicated with two further samples. The SAL-SE and SAE-SE scales hold promise for more detailed studies of student self-efficacy.  相似文献   

Measuring procrastination: Psychometric properties of the Norwegian versions of the Irrational Procrastination Scale (IPS) and the Pure Procrastination Scale (PPS)     

Frode Svartdal 《Scandinavian Journal of Educational Research》2017,61(1):18-30

Procrastination has been defined in different ways. Two instruments—the Irrational Procrastination Scale (IPS) and the Pure Procrastination Scale (PPS)—focus on a core problem in procrastination—the irrational delay of intended behavior. The present paper examined the psychometric properties of the Norwegian translations of these scales. In five samples with students as well as non-students (aggregated n?=?1045), standard psychometric properties of the instruments were assessed and their factor structures were compared in replication analyses. In addition, correlations between the instruments as well as other instruments (i.e., the Susceptibility to Temptation Scale and the Satisfaction with Life Scale) were examined to determine convergent and divergent validity. Overall, the results indicated that both IPS and PPS are suitable for use as measures of procrastination.  相似文献
