The authors report on the development of a brief dyslexia screening measure based on revising the 65-item Hong Kong Behaviour Checklist of Specific Learning Difficulties in Reading and Writing. Teachers’ ratings of 1063 primary students aged 6–14 years on the behaviour checklist provided data for its psychometric evaluation using traditional measurement and Rasch measurement model analyses. Rasch scaling suggested that the revised 36-item checklist could be regarded as a unidimensional scale that assesses global dyslexic dysfunction, and receiver operating characteristics analysis suggested that a score of 18 could be an optimal cut-off score when it is used as a dyslexia screening measure. The validity of this revised checklist was supported by its substantial and significant correlations with external measures of literacy and cognitive skills. Implications of the findings for the use of adaptive testing to provide an effective procedure for screening are discussed.  相似文献

网络媒体的迅速发展深刻地改变了当代大学生的成长环境,网络媒介素养成为当代大学生必需具备的重要素养。调查发现,认知能力的有限使得大学生难以甄别网络信息真伪,易出现盲目从众、沉溺网络等非理性行为。各高校应通过开设网络信息认知课程、开展网络道德法规教育和营造良好的校园网络文化提升大学生的网络媒介素养。  相似文献

As the perceived credibility and availability of conventional sources of applicant information wanes, employers increasingly use online information to evaluate prospective employees' fit. This qualitative study explores how employers communicatively frame online screening—or cybervetting—to inform fit assessments during personnel selection. Findings suggest that employers legitimize cybervetting by framing the practice as risk work (i.e. due diligence and professional identity work), reputation management, efficient, fun, and transformative. Findings evidence shifting understandings of how fit assessments occur and what constitutes a “good fit” and an ideal worker as employers extend organizational surveillance beyond conventional work roles and contexts. Recommendations include assessing cybervetting's effectiveness at accomplishing risk, reputation, and efficiency goals; complicating singular notions of identity; considering bona fide information environments when developing employment legislation; and expanding training to improve employers' and workers' socio-technical and communicative competencies.  相似文献

In schools, screening is an effective method to identify students at-risk for emotional and behavioural disorders. Several intervention programmes such as Positive Behaviour Interventions and Supports, Response to Intervention, and Multi-tiered Systems of Supports call for the use of psychometrically sound screening instruments. This study investigated diagnostic utility of a brief (10-item) screener, the Emotional and Behavioural Screener (EBS) with a sample 312 Lithuanian students. The Strengths and Difficulties Questionnaire was used as a reference point for the investigation. Diagnostic utility statistics (i.e. overall agreement, misleading negatives, sensitivity, specificity and area under the receiver operating characteristic curve) were used to evaluate the usefulness and validity of the EBS. The results indicate, that majority of the diagnostic utility statistics thresholds were met; however, some gender differences were found. In sum, the EBS appears to be an accurate screener discriminating students not at-risk and at-risk for emotional and behavioural problems. Study limitations, future research directions and implications are discussed.  相似文献

Prevalence data of elder abuse from social and health services only present a tip of the iceberg. A large amount of situations of abuse is left undetected. Professionals often lack knowledge and skills on the topic of abuse. Consequently, this paper focuses on supporting professionals to prevent and assess elder abuse by developing and testing the Risk on Elder Abuse and Mistreatment Instrument (REAMI), using a mixed method design. Quantitative data from a widespread screening among 1920 older clients of home care are analysed with exploratory and confirmatory analysis. In addition, 24 professionals who have used the REAMI have been qualitatively interviewed about their practical experience and critical reflection on the instrument and its use. These interviews were transcribed and content analysed. Findings provide evidence of good internal reliability and internal validity of the REAMI and its three dimensions: 1) risk factors of the older person, 2) risk factors of the environment, 3) signals of abuse and mistreatment. Users report an increase of knowledge and awareness among staff, satisfaction with the possibilities for prevention and the user-friendliness and brevity of the REAMI. However, some users are missing a follow-up protocol: what to do when risks are assessed? In the discussion, the argument is developed that the REAMI can be used to examine risk at elder abuse, although an overarching protocol to support prevention and intervention which embeds the detection instrument is needed.  相似文献
