Nutritional Screening in Community-dwelling Older Adults: A Systematic Literature Review

Abstract: Nutrition screening is a process used to quickly identify those who may be at risk of malnutrition so that a full nutrition assessment and appropriate nutrition intervention can be provided. While many nutrition screening tools have been developed, few have been evaluated for use in older adults in the community setting. The aim of this paper is to determine the most appropriate nutrition screening tool/s, in terms of validity and reliability, for identifying malnutrition risk in older adults living in the community. Electronic databases MEDLINE, PUBMED, CINAHL and the Cochrane Library were searched for nutrition screening tools to identify malnutrition or under-nutrition for adults greater than 65 years living in the community. Ten screening tools were found for use in community-dwelling older adults and subjected to validity and/or reliability testing: Mini Nutritional Assessment-Short Form (MNA-SF), Malnutrition Universal Screening Tool (MUST), Nutrition Screening Initiative (NSI), which includes the DETERMINE Checklist and Level I and II Screen, Australian Nutritional Screening Initiative (ANSI), Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN I and SCREEN II), Short Nutritional Assessment Questionnaire (SNAQ), Simplified Nutritional Appetite Questionnaire (SNAQ), and two unnamed tools. MNA-SF appears to be the most appropriate nutrition screening tool for use in community-dwelling older adults although MUST and SCREEN II also have evidence to support their use. Further research into the acceptability of screening tools focusing on the outcomes of nutrition screening and appropriate nutrition intervention are required.

Workplace-based assessment: raters’ performance theories and constructs

Abstract: Weaknesses in the nature of rater judgments are generally considered to compromise the utility of workplace-based assessment (WBA). In order to gain insight into the underpinnings of rater behaviours, we investigated how raters form impressions of and make judgments on trainee performance. Using theoretical frameworks of social cognition and person perception, we explored raters’ implicit performance theories, use of task-specific performance schemas and the formation of person schemas during WBA. We used think-aloud procedures and verbal protocol analysis to investigate schema-based processing by experienced (N = 18) and inexperienced (N = 16) raters (supervisor-raters in general practice residency training). Qualitative data analysis was used to explore schema content and usage. We quantitatively assessed rater idiosyncrasy in the use of performance schemas and we investigated effects of rater expertise on the use of (task-specific) performance schemas. Raters used different schemas in judging trainee performance. We developed a normative performance theory comprising seventeen inter-related performance dimensions. Levels of rater idiosyncrasy were substantial and unrelated to rater expertise. Experienced raters made significantly more use of task-specific performance schemas compared to inexperienced raters, suggesting more differentiated performance schemas in experienced raters. Most raters started to develop person schemas the moment they began to observe trainee performance. The findings further our understanding of processes underpinning judgment and decision making in WBA. Raters make and justify judgments based on personal theories and performance constructs. Raters’ information processing seems to be affected by differences in rater expertise. The results of this study can help to improve rater training, the design of assessment instruments and decision making in WBA.

Long-term effects of a very low-carbohydrate diet and a low-fat diet on mood and cognitive function.

Abstract: Background Very low-carbohydrate (LC) diets are often used to promote weight loss, but the long-term effects on psychological function remain unknown. Methods A total of 106 overweight and obese participants (mean [SE] age, 50.0 [0.8] years; mean [SE] body mass index [calculated as weight in kilograms divided by height in meters squared], 33.7 [0.4]) were randomly assigned either to an energy-restricted (approximately 1433-1672 kcal [to convert to kilojoules, multiply by 4.186]), planned isocaloric, very low-carbohydrate, high-fat (LC) diet or to a high-carbohydrate, low-fat (LF) diet for 1 year. Changes in body weight, psychological mood and well-being (Profile of Mood States, Beck Depression Inventory, and Spielberger State Anxiety Inventory scores), and cognitive functioning (working memory and speed of processing) were assessed. Results By 1 year, the overall mean (SE) weight loss was 13.7 (1.8) kg, with no significant difference between groups (P = .26). Over the course of the study, there were significant time × diet interactions for Spielberger State Anxiety Inventory, Beck Depression Inventory, and Profile of Mood States scores for total mood disturbance, anger-hostility, confusion-bewilderment, and depression-dejection ( P P Conclusions Over 1 year, there was a favorable effect of an energy-restricted LF diet compared with an isocaloric LC diet on mood state and affect in overweight and obese individuals. Both diets had similar effects on working memory and speed of processing. Trial Registration anzctr.org.au Identifier:12606000203550
