Consumer Access, Appraisal, and Application of Services and Information for Dementia (CAAASI-Dem): a validation study.

Objectives: The Consumer Access, Appraisal, and Application of Services and Information for Dementia (CAAASI-Dem) was developed to examine individuals' self-assessed confidence in their ability to access, appraise and use dementia services and information. The CAAASI-Dem is the only tool to date to measure this crucial component of dementia literacy. This study was designed to validate its structural validity.Method: Data was collected from 3277 participants enrolled in an on-line dementia course. The five-factor structure of the CAAASI-Dem, which was derived from a previous exploratory factor analysis, was evaluated using confirmatory factor analysis. Internal reliability, convergent and divergent validity, and known-groups validity were assessed. Results: The five-factor model demonstrated good fit with the observed data with the removal of 2 items and movement of 1 item across the factors. The resultant 24-item five-factor CAAASI-Dem showed very good sub-scale internal reliability and satisfactory convergent and divergent validity. There was good discrimination between groups of participants with different levels of care experience.Conclusion: The results provided evidence for the 24-item CAAASI-Dem as a valid and reliable five-dimensional scale. Limitations of the study are discussed, and recommendations are made for future research and practice.

Measuring consumer access, appraisal and application of services and information for dementia (CAAASI-Dem): a key component of dementia literacy.

BACKGROUND: The ability to locate, navigate and use dementia services and information, either for oneself or in providing care for others, is an essential component of dementia literacy. Despite dementia literacy being understood to be inadequate in many settings, no validated instrument exists to measure these elements. Here we describe the development and preliminary validation of the Consumer Access, Appraisal and Application of Services and Information for Dementia (CAAASI-Dem) tool. METHODS: Items were adapted from existing health literacy tools and guided by discussion posts in the Understanding Dementia Massive Open Online Course (UDMOOC). Following expert review and respondent debriefing, a modified CAAASI-Dem was administered to UDMOOC participants online. On the basis of descriptive statistics, inter-item and item total correlations and qualitative feedback, this was further refined and administered online to a second cohort of UDMOOC participants. Exploratory factor analysis identified underlying factor structure. Items were retained if they had significant factor loadings on one factor only. Each factor required at least three items with significant factor loadings. Internal consistency of factors in the final model was evaluated using Cronbach's alpha coefficients. RESULTS: From a pool of 70 initial items with either a 5-point Likert scale (Not at all confident - Extremely confident; or Strongly agree - Strongly disagree) or a binary scale (Yes - No), 65 items were retained in CAAASI-Dem-V1. Statistical and qualitative analysis of 1412 responses led to a further 34 items being removed and 11 revised to improve clarity. The 31 item CAAASI-Dem-V2 tool was subsequently administered to 3146 participants, one item was removed due to redundancy and EFA resulted in the removal of an additional 4 items and determination of a five factor structure: Evaluation and engagement; Readiness; Social supports; Specific dementia services; and Practical aspects. CONCLUSIONS: The five factors and 26 constituent items in CAAASI-Dem align with functional, critical, and communicative aspects of dementia health literacy from the perspective of the carer. As a screening tool for people living with dementia and their carers, CAAASI-Dem potentially provides a means to determine support needs and may be a key component of the dementia literacy assessment toolbox.

General practitioners attitude and confidence scale for dementia (GPACS-D): confirmatory factor analysis and comparative subscale scores among GPs and supervisors.

BACKGROUND: The attitude of General Practitioner's (GP's) towards dementia and confidence in their clinical abilities impacts on diagnosis rates and management of the condition. The purpose of the present research is to refine and confirm the reliability and validity of the General Practitioner Attitudes and Confidence Scale for Dementia (GPACS-D) as a tool to measure confidence and attitude. METHODS: A sample of 194 GP volunteers attending dementia education workshops were recruited to complete the GPACS-D before and after the workshop. Volunteer respondents comprised both GP Registrars and GP Supervisors. Analyses included Confirmatory Factor Analysis (CFA), measures of internal consistency, Pearson correlations, and a comparison of subscale scores between cohorts (T-Test for independent samples). RESULTS: Findings of the CFA support a 15-item, 3-factor model with four items removed due to poor performance and one item moved between factors. The resultant model exhibited good fit (x2 = 103.88; p = .105; RMSEA = .032; PCLOSE = .915; CFI = .967; TLI = 960), with acceptable internal consistency. Subscales exhibited clear discriminant validity with no underlying relationships between subscales. Finally, total and subscale scores exhibited good discrimination between groups who would be expected to score differently based on experience and level of exposure to dementia. CONCLUSION: The 15-item, 3-subscale GPACS-D is a reliable and valid measure of GP confidence and attitudes toward dementia. The subscales clearly distinguish between groups who might be expected to score differently from each other based on their training or professional experiences. The psychometric properties of the GPACS-D support its use as a research tool.

Development and preliminary psychometric properties of the General Practitioner Attitudes and Confidence Scale (GPACS-D) for dementia.

BACKGROUND: International evidence suggests that dementia is under-diagnosed in the community and that General Practitioners (GPs) are often reluctant to engage to their fullest capability with patients who exhibit cognitive symptoms. This is potentially reflected by a lack of GP knowledge about the syndrome. However, it is also recognised that attitudes and confidence are important in relation to how and to what extent a GP approaches a person with dementia. This research sought to develop a reliable and valid measure of GPs attitudes and confidence towards dementia. METHODS: The General Practitioner Attitudes and Confidence Scale for Dementia (GPACS-D) was developed via a four stage process, including initial content development, pretesting, pilot testing and psychometric evaluation, including Principal Component Analysis (PCA). Participants were recruited for pre-testing (n = 12), test-retest (n = 55), and dementia workshop pre-and post-education evaluation (n = 215). RESULTS: The process of scale development and psychometric evaluation resulted in a 20-item measure of GP attitudes and confidence towards dementia, with 4 items removed due to poor reliability, low sensitivity, or lack of model fit. Among 55 respondents who completed the scale on two occasions with no intervening education, Kappa coefficient scores per item ranged from fair (n = 2, candidates for removal), moderate (n = 5), substantial (n = 15), and almost perfect (n = 2). A test of the sensitivity of item scores to change following dementia education among 215 GPs indicated that, with the exception of one item, all scale responses exhibited significant differences between pre-and post-workshop scores, indicating acceptable sensitivity. With one further item removed due to a low communality score, the final PCA undertaken with the remaining 20 items supports a four-component solution, which accounted for 51.9 % of the total variance. CONCLUSION: The GPACS-D provides a reliable and preliminarily valid measure of GP attitudes and confidence towards dementia. The scales provide useful information for medical educators and researchers who are interested in evaluating and intervening in GP perceptions of the syndrome and their capacity to provide effective care.

Aspects of nursing student placements associated with perceived likelihood of working in residential aged care.

AIMS AND OBJECTIVES: To investigate which aspects of student nurses' experiences of residential aged care facility clinical placements affect perceived likelihood of choosing a career in residential aged care post graduation. BACKGROUND: Poor clinical placement experiences as a student contribute to nurses' reluctance to work in aged care. Various factors have been found to improve the placement experience and influence students' attitudes and employment intentions. Missing from the literature is a quantitative - rather than qualitative - exploration of which attributes of an aged care placement link to perceived likelihood of working in residential aged care post graduation. DESIGN: Supported residential aged care placement programmes were developed for nursing students using an evidence-based best-practice model within an action research framework. Staff formed a mentor group in two facilities. During placement, weekly feedback meetings were held for students and mentors. METHODS: Second-year nursing students (n = 71) participating in a three- or four-week placement programme at two Tasmanian residential aged care facilities (September 2011-May 2013) completed questionnaires on placement experiences. Measures of association (correlation coefficients) were used to assess the effect of a range of variables on the likelihood of working in an aged care facility post graduation. RESULTS: Associations were identified between the likelihood of working in residential aged care post graduation and nurse mentor-student feedback exchange, Teaching and Learning Score and supportiveness of care workers. CONCLUSIONS: This study adds to the literature by providing quantitative evidence that certain aspects of aged care placements influence attitudes to working in these sites post graduation. RELEVANCE TO CLINICAL PRACTICE: To increase interest in working in residential aged care, the teaching and learning environment needs improvement, opportunities should be proffered for mentor-student feedback exchange during placements and care workers need support to mentor effectively.

Bullying and gangs.

BACKGROUND: Although bullying is associated with gangs, questions arise as to whether bullying, as such, takes place within gangs. OBJECTIVE: To provide a critical analysis of bullying as this pertains to youth gangs and especially to violence within gangs, and as applied to the behaviour of individual gang members. STUDY GROUP: Young men between 12 and 25 years of age. METHODS: Review of relevant literature with a view to theorising the nature of the relationship between bullying and violence within a youth gang context. RESULTS: Bullying is associated with the reasons why individuals join gangs and with gang-related behaviour, but the violence within a gang is of a different character than that usually described by the term bullying. CONCLUSION: Bullying has implications for related and/or subsequent types of street violence, but is less relevant for descriptions of violence within a youth gang context as such.

Effect of a dementia education intervention on the confidence and attitudes of general practitioners in Australia: a pretest post-test study.

OBJECTIVES: This study assessed the impact of a Dementia Education Workshop on the confidence and attitudes of general practitioner (GP) registrars (GPR) and GP supervisors (GPS) in relation to the early diagnosis and management of dementia. DESIGN: Pretest post-test research design. SETTING: Continuing medical education in Australia. PARTICIPANTS: 332 GPR and 114 GPS. INTERVENTIONS: Registrars participated in a 3-hour face-to-face workshop while supervisors participated in a 2-hour-modified version designed to assist with the education and supervision of registrars. MAIN OUTCOME MEASURES: The General Practitioners Confidence and Attitude Scale for Dementia was used to assess overall confidence, attitude to care and engagement. A t-test for paired samples was used to identify differences from preworkshop (T1) to postworkshop (T2) for each GP group. A t-test for independent samples was undertaken to ascertain differences between each workshop group. A Cohen's d was calculated to measure the effect size of any difference between T1 and T2 scores. RESULTS: Significant increases in scores were recorded for Confidence in Clinical Abilities, Attitude to Care and Engagement between pretest and post-test periods. GPR exhibited the greatest increase in scores for Confidence in Clinical Abilities and Engagement. CONCLUSIONS: Targeted educational interventions can improve attitude, increase confidence and reduce negative attitudes towards engagement of participating GPs.

Nitrite as regulator of hypoxic signaling in mammalian physiology.

In this review we consider the effects of endogenous and pharmacological levels of nitrite under conditions of hypoxia. In humans, the nitrite anion has long been considered as metastable intermediate in the oxidation of nitric oxide radicals to the stable metabolite nitrate. This oxidation cascade was thought to be irreversible under physiological conditions. However, a growing body of experimental observations attests that the presence of endogenous nitrite regulates a number of signaling events along the physiological and pathophysiological oxygen gradient. Hypoxic signaling events include vasodilation, modulation of mitochondrial respiration, and cytoprotection following ischemic insult. These phenomena are attributed to the reduction of nitrite anions to nitric oxide if local oxygen levels in tissues decrease. Recent research identified a growing list of enzymatic and nonenzymatic pathways for this endogenous reduction of nitrite. Additional direct signaling events not involving free nitric oxide are proposed. We here discuss the mechanisms and properties of these various pathways and the role played by the local concentration of free oxygen in the affected tissue.

Workshops on diagnosis and management of dementia for general practitioners: a pre-post intervention study of dementia knowledge.

OBJECTIVES: To assess improvements in dementia knowledge among general practitioner (GP) registrars and supervisors following their participation in dementia workshops. DESIGN: Pre-post intervention study. SETTING: General practice education in Australia. PARTICIPANTS: 296 GP registrars and 91 GP supervisors. INTERVENTIONS: Registrars participated in a 3-hour face-to-face workshop on diagnosing and managing dementia. Supervisors participated in a 2-hour modified version of the workshop designed to support them in teaching registrars. MAIN OUTCOME MEASURES: The Dementia Knowledge Assessment Scale (DKAS) was used to assess overall dementia knowledge as well as knowledge on four subscales (causes and characteristics; communication and behaviour; care considerations; risks and health promotion). Changes in mean scores and the proportion of participants obtaining a threshold score (90th percentile score preworkshop) were used as measures of improvement. RESULTS: Few registrars and supervisors identified previous experience of formal dementia education. At baseline, mean dementia knowledge scores were 36 for registrars and 37 for supervisors of a total score of 50. Both groups had significantly improved overall dementia knowledge following the workshop with a mean score of 43. Improvements in knowledge were observed for all four DKAS subscales. Between preworkshop and postworkshop periods, there was an increase in the proportion of registrars and supervisors obtaining the threshold score for total DKAS as well as the four subscales. A significantly higher proportion of registrars compared with supervisors obtained the threshold score postworkshop in the areas of causes and characteristics and risks and health promotion. CONCLUSIONS: Prior to the workshop, no differences in overall dementia knowledge were observed between registrars and supervisors. While knowledge improved in all areas for both groups postworkshop, findings from this study suggest the need to include foundational content such as the causes and characteristics of dementia in educational workshops for both trainee and experienced GPs.

Quality clinical placements: The perspectives of undergraduate nursing students and their supervising nurses.

BACKGROUND: Clinical placement for students of nursing is a central component of tertiary nursing programs but continues to be a complex and multifaceted experience for all stakeholders. OBJECTIVES: This paper presents findings from a longitudinal 3-year study across multiple sites within the Australian context investigating the quality of clinical placements. DESIGN: A study using cross-sectional survey. SETTINGS: Acute care, aged care and subacute health care facilities. PARTICIPANTS: A total of 1121 Tasmanian undergraduate nursing students and 932 supervising ward nurses. METHODS: Survey data were collected at completion of practicum from participating undergraduate students and supervising ward nurses across the domains of "welcome and belonging," "competence and confidence: reflections on learning," and "support for learning." In addition, free text comments were sought to further inform understandings of what constitutes quality clinical placements. RESULTS: Overwhelmingly quantitative data demonstrate high-quality clinical placements are provided. Analysis of free text responses indicates further attention to the intersect between the student and the supervising ward nurse is required, including the differing expectations that each holds for the other. While meaningful interpersonal interactions are pivotal for learning, these seemingly concentrated on the relationship between student and their supervisor-the patient/client was not seen to be present. CONCLUSIONS: Meaningful learning occurs within an environment that facilitates mutual respect and shared expectations. The role the patient has in student learning was not made obvious in the results and therefore requires further investigation.

Learning opportunities in a residential aged care facility: the role of supported placements for first-year nursing students.

The residential aged care sector is reportedly a less attractive career choice for nursing students than other sectors. Research shows that students are often fearful of working with residents with dementia when they are inadequately supported on clinical placements by aged care staff. Thirty first-year nursing students attended a 2-week placement in one of two Tasmanian aged care facilities as part of the Wicking Dementia Research and Education Centre Teaching Aged Care Facilities Program, which aims to provide students with a quality aged care placement focusing on dementia palliation. Placement experience and dementia knowledge were evaluated through preplacement and postplacement questionnaires and weekly feedback meetings with mentors and students. Students had more positive attitudes related to aged care and higher dementia knowledge at the end of placement. Students described their interactions with residents with dementia and thought that the placement had increased their capacity to provide quality care to these residents. The findings indicate that residential aged care placements can be productive learning environments for novice nursing students.
