Community Dwelling Older Adults

A meta-analysis of the efficacy of forgiveness interventions in older adults was conducted. International databases (Medline, PsycINFO, Scopus, Web of Science) were searched for studies published from 1990 to 2020 that attempted to promote forgiveness in older adults. Most intervention studies are group treatments targeted towards community-dwelling older adults. Participants in these studies are mainly women. The intervention objectives and contents vary widely and often criteria are not well-defined. Participants that received forgiveness interventions reported significantly higher levels of forgiveness than participants that did not receive treatment. Additionally, forgiveness interventions resulted in more changes in depression, stress and anger than no intervention conditions. Forgiveness treatment also enhances positive states (satisfaction with life, subjective happiness, and psychological wellbeing). The reported effects are moderate. The specific treatment model (e.g., Enright’s, Worthington’s) and format (e.g., group-based interventions and individually delivered programs) do not differentially predict better outcomes. In conclusion, future intervention studies should include more male participants and utilize a broader range of follow-up periods. Caution must be exercised because of the limited number of studies developed to date; researchers must be cautious when generalizing the results.

AbstractBased on a comprehensive literature review of student feedback intervention studies in schools, this chapter provides an overview of found effects on teachers and teaching. The first part summarizes the self-reported cognitive, affective, and motivational effects of student feedback on teachers, which can subsequently lead to behavioral changes in the classroom. In the second part, the focus is on the extent to which these behavioral changes are perceived by students. For the first time, a meta-analysis of changes in students’ perceptions of teaching was carried out for the 18 existing longitudinal studies for this purpose. A small but significant positive weighted mean effect size of d=0.21 for students’ perceived improvement of teaching quality was found, while more in-depth analyses pointed to a beneficial effect of individual support measures for teachers regarding reflection and subsequent development of teaching. Implications for further research and practical implementation of student feedback in schools are discussed.

Using Data

Greater understanding of the mechanisms (mediators) by which behavioral-change interventions work is critical to developing theory and refining interventions. Although systematic reviews have been advocated as a method for exploring mediators, this is rarely done. One challenge is that intervention researchers typically test only two paths of the mediational model: the effect of the intervention on mediators and on outcomes. The authors addressed this challenge by drawing information not only from intervention studies but also from observational studies that provide data on associations between potential mediators and outcomes. They also reviewed qualitative studies of participants’ perceptions of why and how interventions worked. Using data from intervention ( n = 37) and quantitative observational studies ( n = 55), the authors conducted a meta-analysis of the mediation effects of eight variables. Qualitative findings ( n = 6) contributed to more in-depth explanations for findings. The methods used have potential to contribute to understanding of core mechanisms of behavioral-change interventions.

Reduced Risk

Introduction: Moderate alcohol consumption is associated with a reduced risk of type 2 diabetes, but this relation appears stronger for women than men. The reduced risk of diabetes could be explained by improved insulin sensitivity or glycemic status, but results of intervention studies on this relation are inconsistent. Our aim was to conduct a systematic review and meta-analysis of intervention studies investigating the effect of alcohol consumption on insulin sensitivity and glycemic status. Design: Systematic review and meta-analysis of intervention studies. Data sources: PubMed and Embase were searched until May 2013 using a pre-specified search string. Methods: Intervention studies on the effect of more than 2 weeks alcohol consumption on biological markers of insulin sensitivity or glycemic status were identified and assessed on their quality. Pooled standardized mean differences (SMD) were calculated using either fixed or random effects models. Gender-stratified analyses and sensitivity analyses excluding studies with high doses of alcohol (> 40 g/day). In a meta-regression the influence of dosage and duration of intervention was tested. Results: We included 14 intervention studies in a meta-analysis on 6 glycemic endpoints. Alcohol consumption did not influence insulin sensitivity (SMD=0.06 [-0.13 to 0.26]) or fasting glucose (SMD=0.09 [-0.09 to 0.27]). Alcohol consumption reduced HbA1c (SMD=-0.62 [-1.01 to -0.23], P=0.002) and insulin concentrations (SMD=-0.17 [-0.34 to 0.00] P=0.049) compared with the control group. In women, alcohol consumption reduced fasting insulin (SMD=-0.23 [-0.41 to -0.04], P=0.019) and improved insulin sensitivity (SMD=0.19 [-0.03 to 0.41], P=0.087), but no significant differences were observed among men. Results were similar when only studies with moderate alcohol dosages were analysed and were not influenced by dosage and duration of the intervention. Conclusions: This study showed that moderate alcohol consumption may reduce fasting insulin and improve insulin sensitivity among women, but not among men. These effects may provide an explanation for the relation between alcohol consumption and type 2 diabetes. Furthermore, moderate alcohol consumption may reduce HbA1c levels among both men and women.

ObjectivesTo provide a comprehensive synthesis of informal caregivers’ experiences of caring for a significant other following discharge from cardiac surgery.DesignSystematic integrated review without meta-analysis.Data sourcesA bibliographic search for publications indexed in six databases (Cochrane Library, CINAHL, MEDLINE, EMBASE, AMED and PsycINFO), including a scan of grey literature sources (GreyNet International, Google Scholar, Web of Science, WorldCat and the Clinical Trials Registry) was conducted in October 2018.Eligibility criteria for selecting studiesStudies were included if they described views and perspectives of informal caregivers of cardiac surgery patients (non-intervention studies (qualitative and quantitative)), and the effectiveness of interventions to evaluate support programme for informal caregivers of cardiac surgery patients (intervention studies).ResultsOf the 4912 articles identified in searches, 42 primary research studies were included in a narrative synthesis with 5292 participants, including 3231 (62%) caregivers of whom 2557 (79%) were women. The median sample size across studies was 96 (range 6–734). Three major themes emerged from the qualitative study data: (1) caregiver information needs; (2) caregiver work challenges and (3) caregivers adaption to recovery. Across the observational studies (n=22), similar themes were found. The trend across seven intervention studies focused on caregiver information needs related to patient disease management and symptom monitoring, and support for caregivers to reduce symptoms of emotional distress.ConclusionInformal caregivers want to assist in the care of their significant others after hospital discharge postcardiac surgery. However, caregivers feel insecure and overwhelmed and they lack clear/concise discharge information and follow-up support during the early at-home recovery period. The burden of caregiving has been recognised and reported since the early 1990s, but there remains a limited number of studies that assesses the effectiveness of caregiver interventions.PROSPERO registration numberCRD42018096590.

Food Safety Training

Research has shown that traditional food safety training programs and strategies to promote hand hygiene increases knowledge of the subject. However, very few studies have been conducted to evaluate the impact of food safety training on food handlers' attitudes about good hand hygiene practices. The objective of this meta-analytical study was to assess the extent to which food safety training or intervention strategies increased knowledge of and attitudes about hand hygiene. A systematic review of food safety training articles was conducted. Additional studies were identified from abstracts from food safety conferences and food science education conferences. Search terms included combinations of “food safety,” “food hygiene,” “training,” “education,” “hand washing,” “hand hygiene,” “knowledge,” “attitudes,” “practices,” “behavior,” and “food handlers.” Only before- and after-training approaches and cohort studies with training (intervention group) and without training (control group) in hand hygiene knowledge and including attitudes in food handlers were evaluated. All pooled analyses were based on a random effects model. Meta-analysis values for nine food safety training and intervention studies on hand hygiene knowledge among food handlers were significantly higher than those of the control (without training), with an effect size (Hedges' g) of 1.284 (95% confidence interval [CI] = 0.830 to 1.738). Meta-analysis of five food safety training and intervention studies in which hand hygiene attitudes and self-reported practices were monitored produced a summary effect size of 0.683 (95% CI = 0.523 to 0.843). Food safety training increased knowledge and improved attitudes about hand hygiene practices. Refresher training and long-term reinforcement of good food handling behaviors may also be beneficial for sustaining good hand washing practices.
