    The effect of alcohol intoxication on witness memory and performance has been the subject of research for some time, however, whether intoxication affects facial composite construction has not been investigated. Intoxication was predicted to adversely affect facial composite construction. Thirty-two participants were allocated to one of four beverage conditions consisting of factorial combinations of alcohol or placebo at face encoding, and later construction. Participants viewed a video of a target person and constructed a composite of this target the following day. The resulting images were presented as a full face composite, or a part face consisting of either internal or external facial features to a second sample of participants who provided likeness ratings as a measure of facial composite quality. Intoxication at face encoding had a detrimental impact on the quality of facial composites produced the following day, suggesting that alcohol impaired the encoding of the target faces. The common finding that external compared to internal features are more accurately represented was demonstrated, even following alcohol at encoding. This finding was moderated by alcohol and target face gender such that alcohol at face encoding resulted in reduced likeness of external features for male composite faces only. Moderate alcohol intoxication impairs the quality of facial composites, adding to existing literature demonstrating little effect of alcohol on line-up studies. The impact of intoxication on face perception mechanisms, and the apparent narrowing of processing to external face areas such as hair, is discussed in the context of alcohol myopia theory

    <p>Abstract</p> <p>Background</p> <p>In healthcare, a gap exists between what is known from research and what is practiced. Understanding this gap depends upon our ability to robustly measure research utilization.</p> <p>Objectives</p> <p>The objectives of this systematic review were: to identify self-report measures of research utilization used in healthcare, and to assess the psychometric properties (acceptability, reliability, and validity) of these measures.</p> <p>Methods</p> <p>We conducted a systematic review of literature reporting use or development of self-report research utilization measures. Our search included: multiple databases, ancestry searches, and a hand search. Acceptability was assessed by examining time to complete the measure and missing data rates. Our approach to reliability and validity assessment followed that outlined in the <it>Standards for Educational and Psychological Testing</it>.</p> <p>Results</p> <p>Of 42,770 titles screened, 97 original studies (108 articles) were included in this review. The 97 studies reported on the use or development of 60 unique self-report research utilization measures. Seven of the measures were assessed in more than one study. Study samples consisted of healthcare providers (92 studies) and healthcare decision makers (5 studies). No studies reported data on acceptability of the measures. Reliability was reported in 32 (33%) of the studies, representing 13 of the 60 measures. Internal consistency (Cronbach's Alpha) reliability was reported in 31 studies; values exceeded 0.70 in 29 studies. Test-retest reliability was reported in 3 studies with Pearson's <it>r </it>coefficients > 0.80. No validity information was reported for 12 of the 60 measures. The remaining 48 measures were classified into a three-level validity hierarchy according to the number of validity sources reported in 50% or more of the studies using the measure. Level one measures (n = 6) reported evidence from any three (out of four possible) <it>Standards </it>validity sources (which, in the case of single item measures, was all applicable validity sources). Level two measures (n = 16) had evidence from any two validity sources, and level three measures (n = 26) from only one validity source.</p> <p>Conclusions</p> <p>This review reveals significant underdevelopment in the measurement of research utilization. Substantial methodological advances with respect to construct clarity, use of research utilization and related theory, use of measurement theory, and psychometric assessment are required. Also needed are improved reporting practices and the adoption of a more contemporary view of validity (<it>i.e.</it>, the <it>Standards</it>) in future research utilization measurement studies.</p

    Background: Elderly migrants who do not speak the official language of their host country have increased due to extensive international migration, and will further increase in the future. This entails major challenges to ensure good communication and avoid communication barriers that can be overcome by the use of adequate interpreter services. To our knowledge, there are no previous investigations on interpreting practices in multilingual elderly healthcare from different healthcare professionals perspectives. This study examines issues concerning communication and healthcare through a particular focus on interpretation between health professionals and patients of different ethnic and linguistic backgrounds. The central aim of the project is to explore interpretation practices in multilingual elderly healthcare. Methods: A purposive sample of 33 healthcare professionals with experience of using interpreters in community multilingual elderly healthcare. Data were collected between October 2013 and March 2014 by 18 individual and four focus group interviews and analysed with qualitative content analysis. Results: The main results showed that interpreting practice in multilingual elderly healthcare was closely linked to institutional, interpersonal and individual levels. On the organizational level, however, guidelines for arranging the use of interpreters at workplaces were lacking. Professional interpreters were used on predictable occasions planned long in advance, and bilingual healthcare staff and family members acting as interpreters were used at short notice in everyday caring situations on unpredictable occasions. The professional interpreter was perceived as a person who should interpret spoken language word-for-word and who should translate written information. Furthermore, the use of a professional interpreter was not adapted to the context of multilingual elderly healthcare. Conclusion: This study found that interpreter practice in multilingual elderly healthcare is embedded in the organizational environment and closely related to the individuals language skills, cultural beliefs and socio-economic factors. In order to formulate interpreter practice in the context of multilingual elderly healthcare it is important to consider organizational framework and cultural competence, cultural health knowledge, beliefs and customs.Funding Agencies|Vetenskapsradet (The Swedish Research Council), Sweden [521-2013-2533]</p
