Reliability and validity of three questionnaires measuring context-specific sedentary behaviour and associated correlates in adolescents, adults and older adults

BACKGROUND: Reliable and valid measures of total sedentary time, context-specific sedentary behaviour (SB) and its potential correlates are useful for the development of future interventions. The purpose was to examine test-retest reliability and criterion validity of three newly developed questionnaires on total sedentary time, context-specific SB and its potential correlates in adolescents, adults and older adults. METHODS: Reliability and validity was tested in six different samples of Flemish (Belgium) residents. For the reliability study, 20 adolescents, 22 adults and 20 older adults filled out the age-specific SB questionnaire twice. Test-retest reliability was analysed using Kappa coefficients, Intraclass Correlation Coefficients and/or percentage agreement, separately for the three age groups. For the validity study, data were retrieved from 62 adolescents, 33 adults and 33 older adults, with activPAL as criterion measure. Spearman correlations and Bland-Altman plots (or non-parametric approach) were used to analyse criterion validity, separately for the three age groups and for weekday, weekend day and average day. RESULTS: The test-retest reliability for self-reported total sedentary time indicated following values: ICC = 0.37-0.67 in adolescents; ICC = 0.73-0.77 in adults; ICC = 0.68-0.80 in older adults. Item-specific reliability results (e.g. context-specific SB and its potential correlates) showed good-to-excellent reliability in 67.94%, 68.90% and 66.38% of the items in adolescents, adults and older adults respectively. All items belonging to sedentary-related equipment and simultaneous SB showed good reliability. The sections of the questionnaire with lowest reliability were: context-specific SB (adolescents), potential correlates of computer use (adults) and potential correlates of motorized transport (older adults). Spearman correlations between self-reported total sedentary time and the activPAL were different for each age group: rho = 0.02-0.42 (adolescents), rho = 0.06-0.52 (adults), rho = 0.38-0.50 (older adults). Participants over-reported total sedentary time (except for weekend day in older adults) compared to the activPAL, for weekday, weekend day and average day respectively by +57.05%, +46.29%, +53.34% in adolescents; +40.40%, +19.15%, +32.89% in adults; +10.10%, -6.24%, +4.11% in older adults. CONCLUSIONS: The questionnaires showed acceptable test-retest reliability and criterion validity. However, over-reporting of total SB was noticeable in adolescents and adults. Nevertheless, these questionnaires will be useful in getting context-specific information on SB

How Evidence-Based Are the Recommendations in Evidence-Based Guidelines?

From an analysis of cardiovascular risk-management recommendations in guidelines produced by pan-national panels, McAlister and colleagues concluded that fewer than half were based on high-quality evidence

Student consultancy projects playbook: learning outcomes and a framework for teaching practice in an international entrepreneurial context

Consultancy projects as an action learning method have become an integral part of management education at many business schools and universities. As an opportunity to apply management knowledge in practice, they have been proven to be a valuable experience when designed and executed adeptly by academics. Based on our activities and reflection as academics, and interviews with students and companies participating in five consultancy projects, this paper proposes a framework to execute student consultancy projects in the context of international entrepreneurship. Working with small, new, and innovative companies at a foreign location seeking to internationalise, the framework highlights the learning outcomes to be achieved by students along the consultancy process. Such outcomes may be cognitive including the integration of previous knowledge with practical insights, affective such as an appreciation of other’s views, and behavioural including the development of transferable communication and management skills. Additionally, the framework provides a guideline for the necessary teaching practice for managerial learning to take place. While the project’s team and client problem are critical, knowledgeable supervisors are needed especially at the beginning, while the level of intervention needs to be adjusted throughout the process

Patient participation in nursing bedside handover: a systematic mixed-methods review

Background: Numerous reviews of nursing handover have been undertaken, but none have focused on the patients’ role. Objectives: To explore how patient participation in nursing shift-to-shift bedside handover can be enacted. Design: Systematic mixed-methods review. Data sources: Three search strategies were undertaken in July-August 2016: database searching, backwards citation searching and forward citation searching. To be included, papers had to either be research or quality improvement (QI) projects focusing on the patient role. Fifty-four articles were retrieved, including 21 studies and 25 QI projects. Review methods: Screening, data extraction and quality appraisal was undertaken systematically by two reviewers. Research studies and QI projects were synthesised separately using thematic synthesis, then the results of this synthesis were combined using a mixed-method synthesis table. Results: Segregated synthesis of research of patients’ perceptions revealed two contrasting categories; (1) patient-centred handover and (2) nurse-centred handover. Segregated synthesis of research of nurses’ perceptions included three categories: (1) viewing the patient as an information resource; (2) dealing with confidential and sensitive information; and (3) enabling patient participation. The segregated synthesis of QI projects included two categories: (1) nurse barrier to enacting patient participation in bedside handover; and (2) involving patients in beside handover. Once segregated findings were configured, we discovered that the patients’ role in bedside handover involves contributing clinical information related to their care or progress, which may affect patient safety. Barriers relate to nurses’ concerns for the consequences of encouraging patient participation, worries for sharing confidential and sensitive information and feeling hesitant in changing their handover methods. The way nurses approach patients, and how patient-centred they are, constitute further potential barriers. Strategies to improve patient participation in handover include training nurses, making handovers predictable for patients and involving both patients and nurses throughout the change process. Conclusions: Using research and QI projects allowed diverse findings to expand each other and identify gaps between research and heuristic knowledge. Our review showed the tension between standardising handovers and making them predictable for patient participation, while promoting tailored and flexible handovers. Further investigation of this issue is required, to understand how to train nurses and ensure patients’ viewpoint is captured. Many barriers and strategies identified QI projects were from the nurse perspective, thus caution interpreting results is required. We recommend steps be taken in the future to ensure improved quality of QI projects

Regulation of Septin Dynamics by the Saccharomyces cerevisiae Lysine Acetyltransferase NuA4

In the budding yeast Saccharomyces cerevisiae, the lysine acetyltransferase NuA4 has been linked to a host of cellular processes through the acetylation of histone and non-histone targets. To discover proteins regulated by NuA4-dependent acetylation, we performed genome-wide synthetic dosage lethal screens to identify genes whose overexpression is toxic to non-essential NuA4 deletion mutants. The resulting genetic network identified a novel link between NuA4 and septin proteins, a group of highly conserved GTP-binding proteins that function in cytokinesis. We show that acetyltransferase-deficient NuA4 mutants have defects in septin collar formation resulting in the development of elongated buds through the Swe1-dependent morphogenesis checkpoint. We have discovered multiple sites of acetylation on four of the five yeast mitotic septins, Cdc3, Cdc10, Cdc12 and Shs1, and determined that NuA4 can acetylate three of the four in vitro. In vivo we find that acetylation levels of both Shs1 and Cdc10 are reduced in a catalytically inactive esa1 mutant. Finally, we determine that cells expressing a Shs1 protein with decreased acetylation in vivo have defects in septin localization that are similar to those observed in NuA4 mutants. These findings provide the first evidence that yeast septin proteins are acetylated and that NuA4 impacts septin dynamics
