Trifactor Models for Multiple-Ratings Data

In this study we extend and assess the trifactor model for multiple-ratings data in which two different raters give independent scores for the same responses (e.g., in the GRE essay or to subset of PISA constructed-responses). The trifactor model was extended to incorporate a cross-classified data structure (e.g., items and raters) instead of a strictly hierarchical structure. we present a set of simulations to reflect the incompleteness and imbalance in real-world assessments. The effects of the rate of missingness in the data and of ignoring differences among raters are investigated using two sets of simulations. The use of the trifactor model is also illustrated with empirical data analysis using a well-known international large-scale assessment.     

A comparison of mental health literacy,attitudes, and help-seeking intentions among domestic and international tertiary students

Limited research has examined distress or help-seeking knowledge and attitudes among international students. The aim of this study was to examine psychological distress, mental health literacy (MHL), and help-seeking attitudes and intentions among a sample of domestic and international tertiary students. The sample comprised 357 domestic and international tertiary students. Participants completed an online questionnaire package, with measures relating to distress, MHL, help-seeking attitudes, and help-seeking intentions. International student status was predictive of lower scores on MHL, help-seeking attitudes, and help-seeking intentions for suicidal ideation. Student group was not predictive of help-seeking intentions for emotional problems or psychological distress, but international students had lower help-seeking intentions for suicidal ideation. Educational interventions targeting MHL and help-seeking attitudes and intentions among international students may be required to improve help-seeking behaviours.     

Experiential avoidance and aversive visual images: response delays and event-related potentials on a simple matching task

In Experiment 1, participants high (n=15) or low in avoidance (n=14), as measured by the Acceptance and Action Questionnaire, completed a simple matching task that required them to choose whether or not to look at an aversive visual image. Only the high-avoidance participants took longer to emit a correct response that produced an aversive rather than a neutral picture. Additionally, the high-avoiders reported greater levels of anxiety following the experiment even though they rated the aversive images as less unpleasant and less emotionally arousing than their low-avoidant counterparts. In Experiment 2, three groups, representing high-, mid- and low-avoidance (n=6 in each) repeated the matching task with the additional recording of event-related potentials (ERPs). The findings of Experiment 1 were replicated in terms of reaction times and subjective ratings. The ERPs confirmed that the participants attended to the content of the images and differentiated between the aversive and neutral image types. The ERPs also showed significantly greater negativity for electrodes over the left hemisphere relative to the midline for only the high-experiential avoidance (EA) group. Given the left hemisphere dominance for language, the data suggest that the high-EA group engaged in verbal strategies to regulate their emotional responses.     

Balancing Ethical Principles in Emergency Medicine Research

This paper attempts to provide a broader view into the ethical issues surrounding the field of emergency medicine (EM) research. It starts from defining bioethically relevant features of EM and presents this field in the context of different models of health care provider–patient relationship. The paper also provides a short overview of the “post-Nuremberg” evolution of the main international research ethics guidelines relevant to EM research which demonstrates a tendency of liberalization of research on incapable persons. This tendency culminates with the exceptions to informed consent for EM research which is supposed to be balanced by other research ethics principles, especially a careful rationing of risks and benefits. This finally brings us towards a critical analysis of the minimal risk standard which is one of the main fundamental safeguards in EM research. An earlier version of this paper was presented at The 7th International Conference on Bioethics on “The Ethics of Research in Emergency Medicine”, held on June 2, 2006, Warsaw, Poland.

MAX EITINGON'S RISE AND DECLINE: THE BERLIN YEARS

Max Eitingon's main achievement was the foundation of the Berlin psychoanalytic Poliklinik that served both as an outpatient center and a training institute. Another area of his responsibility was the Verlag, the International Psychoanalytic Press. By 1926, he occupied several leading positions, including presidency of the International Psychoanalytical Association and editorship of the major psychoanalytic journal of the time. The basis of his power was his personal relationship with Freud, as well as his monetary wealth, which he put into the service of the Freudian cause. By 1932, he had suffered an overall setback, however, with the Berlin Institute losing its best teachers, the Verlag barely escaping bankruptcy, and the journal's editorship returning to Vienna.     

Metacognition and low achievement in mathematics: The effect of training in the use of metacognitive skills to solve mathematical word problems

The central question underlying this study was whether metacognition training could enhance the two metacognition components—knowledge and skills—and the mathematical problem-solving capacities of normal children in grade 3. We also investigated whether metacognitive training had a differential effect according to the children's mathematics level. A total of 48 participants took part in this study, divided into an experimental and a control group, each subdivided into a lower and a normal achievers group. The training programme took an interactive approach in accordance with Schraw's (1998 Schraw, G. 1998. Promoting general metacognitive awareness. Instructional Science, 26: 113–125. [Crossref], [Web of Science ®] , [Google Scholar]) recommendation and was carried out over five training sessions. Results indicated that children in the training group had significantly higher post-test metacognitive knowledge, metacognitive skills, and mathematical problem-solving scores. In addition, metacognitive training was particularly beneficial to the low achievers. Thus metacognitive training enabled the low achievers to make progress and solve the same number of problems on the post-test as the normal achievers solved on the pre-test.     

Elaborate reflections on a simple manifesto

In an earlier article (^{McFall, 1991}), I urged clinical psychologists to work toward the goal of integrating science and practice and proposed the adoption of a principle and two corollaries aimed at achieving this goal. In general, I argued that all aspects of clinical psychology must be guided by the highest scientific and ethical standards, that clinical practice be limited to empirically supported procedures, and that clinical training be devoted to producing clinical scientists. In the present article, I elaborate and defend these points by offering reflections on a number of submitted questions provoked by the earlier article. I address four major issues: the philosophical foundations for a scientific epistemology, the implications of this epistemology for clinical practice, the implications for clinical training, and the likely impact of adopting this epistemology on the field of clinical psychology.     

Coalitional Capacities and Environmental Strategies to Prevent Underage Drinking

Coalitions are the most common platform for implementing community-level environmental strategies (ES), such as media, policy, or enforcement for substance use prevention. The current study examines the associations between two types of coalition capacity (general and innovation-specific) and ES implementation efforts and outputs within 14 intervention communities over a three-year period. Efforts refer to the amount of energy exerted to implement an ES while outputs refer to the materials produced through these efforts. Quantitative measures of capacity were provided by coalition key informants and expert-raters. Additionally, Training and Technical Assistance (TTA) provided proactively to improve the implementation of ES was also examined. Greater general capacity, as rated by a coalition informant, was associated with more ES policy effort. Both expert-rated general and innovation-specific capacity, however, were associated with greater ES outputs. Study results also found that community coalitions that endorsed weaker mobilization, structure and task leadership, (measures of general capacity), utilized more TTA compared to those who perceived their coalition as having greater capacity. Moreover, communities that utilized more TTA resources reported a greater number of successful policy changes. The study supports the need to consider both general and innovation-specific capacity for ES implementation and offers promising preliminary findings regarding the role of TTA for improving coalitions’ capacity to facilitate policy change.
