ABSTRACT

The Multifactorial Memory Questionnaire (MMQ) is a participant-reported measure of memory satisfaction, ability, and strategy use. Initially validated with healthy older adults, it has since been used in many different populations and settings for a variety of purposes. We conducted a systematic review and meta-analysis of the measurement properties of the MMQ across multiple, diverse studies. Methods: The study was designed using the Consensus-Based Standards for the Selection of Health Measurement Instruments and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We calculated aggregate statistics and evaluated the methodological quality of 29 studies retrieved from PsycINFO, MEDLINE, EMBASE, and Web of Science. Results: Analyses revealed high-quality evidence for internal consistency, stability, measurement error, convergent validity, and known-groups validity of the three MMQ scales. There was moderate-quality evidence for responsiveness and structural validity, with some studies identifying separate factors for internal and external memory strategy use. Measurement properties were similar across languages, participant samples, and study designs. Conclusions: The MMQ is a valid, reliable, and responsive measure across diverse settings and populations. Future research is needed to determine whether more detailed information can be obtained from the scales, specifically, internal versus external strategy use.  相似文献

The purpose is to identify the motivations and barriers to physical activity (PA) among the three largest ethnic groups in Hawaii (Hawaiians/part-Hawaiians, Japanese, and Filipinos). University of Hawai'i students (N = 32, aged 18+) self-identified as one of those ethnicities participated in focus groups. There are more common themes than ethnic-specific variations in factors influencing PA. PA is understood as exercise among all groups; leisure time PA like running and surfing are common activities. Results were more similar among Hawaiian and Japanese than with Filipino participants. The findings offer an opportunity for improving cross-cultural and culture-specific PA interventions for those ethnicities.  相似文献

Abstract

To take someone's ideas seriously enough to question them is a significant form of respect. It builds communities where controversy stimulates thought instead of enmity; what the clash of ideas leads not to victory for one party but to new questions and news answers for everyone.

To resolve the impasse between skeptic, idealist and positivist as to whether or not historical inquiry can be objective, an affirmative answer is argued by exposing, clarifying and challenging the common presupposition: the thesis of scientific value neutrality. The argument applies a more explicit version of the Braithwaite— Churchman‐Rudner position to history and thus challenges the prevalent claim that history, unlike the law, has but one goal, the establishment of truth about the past. The important yet neglected residual issue concerns what ‘objectivity’ means when inquiry (historical or scientific) is construed as a goal‐directed activity controlled by epistemic and pragmatic utilities.  相似文献

Allies are frequently studied from the viewpoint of dominant group members. Three studies took a different perspective by investigating how people of color perceive both White allies and allies of color. Study 1 used content analysis of qualitative data from 80 people of color to describe eight major themes of ally perception. With samples of 182 and 195 people of color, Studies 2 and 3 employed exploratory and confirmatory factor analysis to identify two subscales, informed action and affirmation, based on the themes. Both independent and paired samples t tests showed that people of color rating a White ally versus an ally of color perceived significantly less willingness to engage racial issues. Findings are discussed in relation to existing allies research.  相似文献

Law enforcement personnel regularly present suspects to eyewitnesses using showups. In this study, we examined the impact of the presence of stolen property on live showup identification performance. Two hundred seventy university students were exposed to a simulated theft. During the subsequent showup, we manipulated the presence of the target and stolen property. Binary logistic regression analyses indicated that both factors independently predicted the accuracy of identification decisions. Participants were more accurate when the target was in the showup and when the stolen property was present during the identification. Consistent with the item, context, and ensemble theory of recognition, the presence of stolen property led to an increase in sensitivity, suggesting ensemble formation. Future research on showups should continue to examine contextual variables that may lead to changes in sensitivity or criterion shift. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Improving human systems integration through technologically advanced training and performance aids has become increasingly important to military transformation. Measures of improved cognitive and coordination processes arising from the employment of transformational tools are necessary to guide the refinement and future development of such technologies. In this article, we describe a cognitive load theory approach to developing a combinatory measure of individual workload and team performance following an experimental intervention involving training and a decision support system. We discuss how indicators of what we term team cognitive efficiency can improve assessing the effectiveness of transformational processes and technologies.  相似文献

Abstract

Thirty-two patients with panic disorder, with or without agoraphobic limitations, were treated with alprazolam (mean dose 3.5 mg/d) plus brief behavioral guidance in an open study during eight weeks. The sample had a notorious severity in the frequency of panics and phobic avoidance but was only mildly depressed. Before starting treatment the presence of demoralized mood and extensive avoidance were significant indicators of clinical severity, whereas the presence of dizziness as a relevant somatic complaint was not related to higher severity. After eight weeks of treatment a clinical improvement equal to or exceeding 80% of change was obtained in all cases (29) who completed treatment. Ninety-two percent of the patients were panic free at the end of treatment. There were significant reductions in all the scales with comparable declines in the subgroups formed according to the presence or absence of agoraphobic avoidance and demoralization. The data suggested that moderate doses of alprazolam could be a quick and effective treatment for panic-agoraphobic patients in the short term. The behavioral guidance probably helped in reducing agoraphobic avoidance and in obtaining global good effectiveness although this awaits controlled tests. Finally, the similarity in the response to treatment regardless of the presence of extensive avoidance or demoralized mood argues in favor of not considering the different variants of panic-agoraphobic syndrome differently, at least in samples with similar severity to the present one.  相似文献
