The current study examined the efficacy of a 1 month future time perspective modification intervention over a 1 month and 6 months period. Participants (N = 92) with elevated scores on measures of depressive symptoms or suicidal ideation were assigned to either the intervention condition or a no-intervention control condition. A repeated-measures manova revealed that those in the time perspective modification intervention condition showed significant reductions in psychache and hopelessness at 1 month, relative to those in the control condition. Repeated-measures manovas did not reveal significantly greater changes in depressive symptoms, suicidal ideation, or future time perspective. No results at 6 months were found to be significant. These results suggest that a future time perspective modification intervention can reduce important predictors of suicidality, although the sustainability of these gains and their relation to suicide is unclear. / Thesis (Master, Psychology) -- Queen's University, 2011-08-29 13:29:07.463

<p>Population growth and increasing life standards contributed to a high demand for food worldwide. Simultaneously, there is growing evidence that more food is being lost or wasted through the different stages of the supply chain. In the developed world, including the United States, consumer waste often constitutes more than 60% of all food losses. </p> This dissertation explores the problem of consumer waste from three different perspectives. In the first essay, a game-theoretic model of a direct interaction between consumers and a retailer with monopoly power is developed to capture the effects of dynamic pricing on the transfer of perishable inventory to consumers. The retailer chooses its optimal price taking into account both retailer and consumer preservation. As long as the retailer’s inventory is well preserved, its price will be low inducing consumers to stockpile and waste more food. Consumers may also waste more if their own preservation level is relatively high. The second essay focuses on governmental policies aimed at reducing consumer waste, such as a tax and a subsidy. Using microeconomic analysis, closed-form solutions for a social-optimal food waste tax and subsidy are derived. The government may impose this tax to increase the cost of waste disposal for households while using tax revenue to sponsor food preservation efforts. It is shown that the tax might not be an effective instrument if the responsiveness of food waste to this tax is low. Finally, the third essay investigates the impact of a nutrition education program on school-cafeteria waste. This program was implemented to promote the health benefits of consuming fruits and vegetables among elementary school children. Comparing food waste data in the treatment and control groups, we found no statistically significant evidence of either increased selection or consumption of fruits and vegetables in the treatment group.

Children in care (e.g., foster care) are at risk of a variety of negative developmental outcomes. Of particular concern are their often poor academic outcomes. Indeed, children in care often have below grade-level performance on math and reading, increased rates of school drop out, and learning disabilities. Despite these difficulties, relatively little research has been conducted to try to ameliorate the problem. The present thesis, consisting of three independent randomized controlled trials (RCTs), sought to address the need for improved educational outcomes for children in care. The first RCT was an evaluation of a one-on-one tutoring program, TutorBright. Children in care were randomized to either a tutoring group or a waitlist control group and assessed on their math and reading skills, as well as on other educationally relevant domains (executive functioning, behaviour, and caregiver involvement in school-related activities), pre and post test. ANCOVA via multiple regression revealed that the children in care that had received tutoring, compared to the waitlist control group, made significantly greater gains in reading comprehension (Hedges’ g = 0.34), reading fluency (g = 0.16), and math calculation (g = 0.39). Moreover, executive functioning and self-reported symptoms of PTSD (for older children) were significant moderators of the effects of tutoring. No significant spill-over effects of tutoring were found. The second RCT, building upon previous RCTs by Flynn et al. (2012) and Harper and Schmidt (2016), evaluated whether a shorter version (i.e., 15 weeks) of a one-on-one Direct Instruction tutoring program, Teach Your Children Well (TYCW), was as effective as a longer version of TYCW (i.e., 25 weeks) on improving the math and reading skills for children in care. ANCOVA via multiple regression did not reveal any significant group differences in academic performance for any of the WJ-III subtests. Collapsing across the two intervention conditions, follow-up paired samples t-tests revealed significant improvement in Letter-Word Identification (Cohen’s d = 0.22), Reading Fluency (d = 0.36), Calculation (d = 0.38), Math Fluency (d = 0.47), Applied Problems (d = 0.30), and Broad Reading (d = 0.30) and Broad Math (d = 0.40) composite scores, suggesting that the 15-week and 25-week TYCW programs were equally effective in improving math and reading skills. Moreover, an attribute-treatment interaction analysis revealed that children with higher executive functioning benefited more from the shorter tutoring dosage for Calculation. The third RCT was a small pilot study that aimed to assess whether working-memory training (WMT) can enhance: 1) working memory capacity, in the short and longer term (i.e., immediately following the completion of WMT and 6-months later), 2) symptoms of Attention Deficit Hyperactivity Disorder (i.e., inattention, hyperactivity, and executive functioning) in the short and longer term, and, 3) math and reading skills at 6-months post WMT. The findings from this study suggested that WMT can improve verbal working memory (g = 0.35) as well as visuo-spatial short-term memory (g = 1.10) in the shorter term but not in the longer term. Moreover, WMT did not have a significant impact on improving symptoms of ADHD or math and reading skills. Together, the results of this dissertation indicate that the math and reading skills of children in care can be improved via tutoring. The findings highlight the importance of providing children in care with effective academic supports in order to help them reach their full potential.

Yes / Introduction A key priority for the UK National Health Service and patients is to ensure that medicines are used safely and effectively. However, medication changes are not always optimally communicated and implemented when patients transfer from hospital into community settings. Heart failure is a common reason for admission to hospital. Patients with heart failure have a high burden of morbidity, mortality and complex pharmacotherapeutic regimens. The Improving the Safety and Continuity Of Medicines management at Transitions of care programme comprises a cluster randomised controlled trial which will test the effectiveness of a complex behavioural intervention aimed at improving medications management at the interface between hospitals discharge and community care. We will conduct a rigorous process evaluation to inform interpretation of the trial findings, inform implementation of the intervention on a wider scale and aid dissemination of the intervention. Methods and analysis The process evaluation will be conducted in six purposively selected intervention sites (ie, hospital trusts and associated community pharmacies) using a mixed-methods design. Fidelity and barriers/enablers of implementation of the Medicines at Transitions Intervention (MaTI) will be explored using observation, interviews (20 patients, 40 healthcare professionals), surveys and routine trial data collection on adherence to MaTI. A parallel mixed analysis will be applied. Qualitative data will be thematically analysed using Framework analysis and survey data will be analysed descriptively. Data will be synthesised, triangulated and mapped to the Consolidated Framework for Implementation Research where appropriate. The process evaluation commenced on June 2018 and is due to end on February 2021. Ethics and dissemination Approved by Research Ethics Committee and the UK Health Research Authority REC: 18/YH/0017/IRAS: 231 431. Findings will be disseminated via academic and policy conferences, peer-reviewed publications and social media. Trial registration number ISRCTN66212970.

Background In patients with diabetes mellitus (DM) or chronic kidney disease (CKD), established cardiovascular disease (CVD) is associated with an increased risk of recurrent events and poor outcome. Ischemic stroke after an acute myocardial infarction (AMI) is a devastating event that carries high risks of decreased patient independence and death. Among patients with DM or CKD, the risk of an ischemic stroke within a year following an AMI is not known. Improved risk factor control is required to reduce the likelihood of CVD recurrence. Guidelines recommend target lipid profile and blood pressure values; however, data show that these targets are often not met. Therefore, there remains an urgent need for improved cardiovascular secondary preventive follow- up. Aims The aims of the present studies were to define trends in the incidence and predictors of ischemic stroke after an AMI in patients with DM or CKD. Furthermore to assess whether secondary preventive follow-up with nurse-based telephone follow-up including medication titration after CVD improves risk factor values in patients with DM or CKD and to investigate if this method performs better than usual care to implement a new treatment guideline in diabetic patients. Methods To assess the risk of post-AMI ischemic stroke, patient data were obtained from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS-HIA). In separate studies, we compared a total of 173 233 AMI patients with and without DM, and 118 434 AMI patients with and without CKD. Within the nurse-based age-independent intervention to limit evolution of disease (NAILED) trial, we investigated a nurse-based cardiovascular secondary preventive follow-up protocol. Patients with acute coronary syndrome, stroke, or transient ischemic attack were randomized to receive either nurse-based telephone follow-up (intervention) or usual care (control). Low-density lipoprotein (LDL-C) levels and blood pressure (BP) were measured at 1 month (baseline) and 12 months post- discharge. Intervention patients with above-target baseline values received medication titration to achieve treatment goals, while the measurements for control patients were forwarded to their general practitioners for assessment. We calculated the changes in LDL-C level and BP between baseline and 12 months post-discharge, and compared  these changes between 225 intervention patients and 215 control patients with concurrent DM or CKD. During the course of the NAILED trial, new secondary preventive guidelines for DM patients were released, including a new LDL-C target value. To assess adherence to the new guidelines within the NAILED trial, we compared LDL-C levels in the 101 intervention patients and 100 control patients with DM. Results Ischemic stroke after AMI The rates of ischemic stroke within one-year after admission for an AMI decreased over time, from 7.1% in 1998–2000 to 4.7% in 2007–2008 among DM patients, and from 4.2% to 3.7% during the same time periods for non-diabetic patients. Lower stroke risk was associated with percutaneous coronary intervention (PCI) and initiation of secondary preventive treatments in-hospital. In-hospital ischemic stroke occurred in 2.3% of CKD patients and 1.2% of non-CKD patients, with no change in these incidences over time. The rates of one-year post- discharge ischemic stroke decreased between 2003–2004 and 2009–2010 from 4.1% to 2.5% among CKD patients, and from 2.0% to 1.3% among non-CKD patients. Lower rates of post-discharge stroke were associated with PCI and statins. Cardiovascular secondary preventive follow-up Among DM and CKD patients with above-target baseline values in the NAILED trial, the median LDL-C value at 12 months was 2.2 versus 3.0 mmol/L (p&lt;0.001) and median systolic BP was 140 versus 145 mmHg (p=0.26) for intervention and control patients, respectively. Before the guideline change, 96% of the intervention and 70% of the control patients reached the target LDL-C value (p&lt;0.001). After the guideline change, the corresponding respective proportions were 65% and 36% (p&lt;0.001). Conclusion Ischemic stroke is a fairly common post-AMI complication among patients with DM and CKD. This risk of stroke has decreased during recent years, possibly due to the increased use of evidence-based therapies. Compared with usual care, cardiovascular secondary prevention including nurse-based telephone follow-up improved LDL-C values at 12 months after discharge in patients with DM or CVD, and led to more efficient implementation of new secondary preventive guidelines.

Infertility is a frequently occurring chronic health condition, which often persists throughout the reproductive years. Heightened anxiety symptoms often are comorbid with infertility diagnoses. Women experiencing infertility, and particularly those with anxiety symptoms, characterize an emerging population that deserves special attention. However, women experiencing infertility have identified barriers to seeking psychotherapy (e.g., fears of being dismissed from fertility treatment and/or stigmatized). Consequently, women diagnosed with infertility need a psychotherapy that not only can reduce these symptoms, but can also be private and convenient. The current study translated an empirically tested in-person mind/body protocol into an internet-based intervention to suit the needs of this population. Seventy-one women were randomly assigned to the intervention or a wait-list control. At the close of the study, only three participants had completed the intervention. At mid-assessment, relative to the wait-list group, the intervention group had a lower level of depressive symptoms and, for those with elevated anxiety symptoms at baseline, a lower level of anxiety symptoms. The findings suggest that even a partially completed internet-based intervention can reduce the anxiety and depressive symptoms of women with a diagnosis of infertility.

Leadership is important to quality improvement initiatives in healthcare. However, few studies have evaluated leadership interventions to enhance nurses’ use of guideline recommendations in the field of knowledge translation. Purpose: To develop and evaluate an intervention designed to operationalize a leadership strategy composed of relations, change, and task-orientated leadership behaviours, and to examine its influence on nurses’ use of guideline recommendations in home-care nursing. Design: Sequential mixed methods pilot study with post-only cluster randomized controlled trial. Methods Phase I: Intervention Development 1. A participatory approach was used at a community healthcare organization with 23 units across the province of Ontario, Canada. The guideline selected was developed by the Registered Nurses’ Association of Ontario for the assessment and management of foot ulcers for people with diabetes. 2. Integrative literature review, qualitative interviews, and baseline chart audits were conducted. 3. Four units were randomized to control or experimental groups. 4. Clinical and management leadership teams participated in a 12-week intervention consisting of printed materials, interactive workshop, and teleconferences. Participants received summarized chart audit data, identified priority indicators for change, and created a team leadership action plan to address barriers and influence guideline use. Phase II: Evaluation 5. Chart audits compared differences in nursing process and patient outcomes. Primary outcome: eight-item nursing assessment score. 6. Qualitative interviews evaluated the intervention and leadership behaviours. Results: No significant difference was found in the primary outcome. A significant difference was observed in nurses’ documentation of five priority indicators chosen by the experimental groups (p=.02). Gaps in care included: 53%, 76%, and 94% of patients not assessed for ulcer depth, foot circulation, or neuropathy (respectively); 75% and 93% did not receive wound debridement or hydrogel dressings. Receiving data to identify priority indicators for change and developing a leadership action plan were reported as useful to guideline implementation. The experimental group described using more relations-oriented leadership behaviours conducting audit and feedback, and sending reminders. Conclusion: Findings from this pilot study suggest that leadership is a team process involving relations, change, and task-oriented behaviours enacted by managers and clinical leaders. A leadership model is proposed as a beginning taxonomy to inform future leadership intervention studies.
