Mobile applications for encouraging blood donation: A systematic review and case study.

Objectives: Given the current shortage of blood donors in the USA, researchers have tried to identify different strategies to attract more young people and spread the voice of donors' needs. Methods: A systematic literature review is conducted to investigate the current mobile applications used to track, attract, and retain donors. We also provide some preliminary results of a pilot study, based on a cross-sectional survey of 952 participants (aged 18 to 39), about the willingness of donors to use mobile apps as tools for encouraging blood donation. The data is collected using a 20-item questionnaire, which includes four constructs of the Theory of Planned Behavior to assess the respondents' willingness to donate blood. A range of statistical techniques, including univariate analysis, multivariate analysis, and structural equation modeling, were utilized to analyze the collected data. Results: The 37 research articles, selected after applying several exclusion criteria, are classified into five main categories. The majority of the research (44.1%) is about using mobile apps to find blood donors and blood centers, followed by publications on using mobile apps to encourage blood donation (26.4%) and to recruit blood donors (14.7%). The remaining studies are about retaining blood donors (8.8%) and using mobile apps for scheduling donations (5.8%). Our pilot case study suggests that 73% of participants have favorable perceptions toward a blood donation mobile app. Conclusions: Many efforts have been undertaken to employ mobile apps to make blood donations more convenient and create communities around donating blood. The case study findings suggest a high level of readiness of using mobile apps for blood donation among the younger generation.

Patterns in older adults' perceived chronic stressor types and cognitive functioning trajectories: Are perceived chronic stressors always bad?

PURPOSE: Previous studies have linked levels of perceived chronic stress to older adults' cognitive functioning, but few have focused on the impact of chronic stressor types. Thus, this study aimed to (1) identify patterns of chronic stressor types and (2) examine the effects of these patterns on cognitive functioning trajectories among older adults. METHODS: Two longitudinal studies were conducted separately to test the study aims and ensure replicability across samples and time points. Both used three timepoints (Study 1: 2006, 2008, and 2010, n = 6974; Study 2: 2012, 2014, and 2016, n = 6604) collected from older Americans in the Health and Retirement Study. Participants did not overlap between the two studies. Latent class analyses were conducted to identify chronic stressor-type patterns. Latent growth curve models were used to test the effects of chronic stressor-type patterns on cognitive functioning trajectories. RESULTS: Three latent classes of stressor types were identified in both studies: egocentric (4.56%; 5.85%), nonegocentric (8.58%; 10.03%), and low stressor (86.86%; 84.12%). In both studies, compared to the low stressor class, the egocentric stressor class had significantly lower initial cognitive scores (B = -0.72, ρ < 0.001; B = -0.46, ρ < 0.05), while the nonegocentric stressor class did not have significantly different initial scores, with covariates controlled. Additionally, in Study 1, the nonegocentric stressor class had significantly slower cognitive decline rates than the low stressor class (B = 0.11, ρ < 0.05). CONCLUSIONS: Findings suggested that nonegocentric stressors are an important stressor source in late adulthood but are less detrimental to cognitive functioning than egocentric stressors. Health management interventions may reduce older adults' cognitive health disparities caused by self-health and financial stressors. More support, including financial subsidies, caregiver stress management training, or support groups, should be provided to older caregivers, especially those with few resources.

The Contribution of Psychological Resilience and Job Meaningfulness to Well-being of Working Cancer Survivors.

BACKGROUND: Although studies suggest that cancer survivors face workplace obstacles, to date there has been little empirical research regarding the personal and environmental factors that can help cancer survivors adjust to work. The purpose of this study was to examine how working survivors' resilience and job meaningfulness were related to their well-being outcomes, including lower cancer-related intrusive thoughts, fatigue, and presenteeism. METHODS: We recruited 200 full-time employed cancer survivors from online participant panels using Qualtrics. Participants responded to an online survey that measured their resilience, job meaningfulness, job-related psychological distress, and well-being outcomes. We conducted descriptive statistical analysis, confirmatory factor analysis, and moderated mediated analysis to examine the psychological process in which resilience and job meaning are associated with cancer survivors' mental health and work outcomes. Findings: The relationship between cancer survivors' resilience and their well-being outcomes depended on job meaningfulness. For survivors whose jobs were not highly meaningful, their resilience was related to reduced job-related psychological distress, which, in turn, was related to lower intrusive thoughts, fatigue, and presenteeism. For survivors with highly meaningful jobs, they did not need to rely on resilience to protect them from workplace psychological distress and other negative outcomes. Conclusion/Application to Practice: It is important for working cancer survivors to develop resilience, especially when they do not perceive their work as highly meaningful. Successful resilience-building interventions can buffer the negative impact of low job meaningfulness and help working survivors achieve better outcomes. In addition, organizations can actively help enrich survivors' jobs to increase perceived meaningfulness.

A pilot study of expressive writing intervention among Chinese-speaking breast cancer survivors.

OBJECTIVE: Little attention has been focused on Asian American breast cancer survivor's psychological needs. No outcome-based psychosocial interventions have been reported to target at this population. Expressive writing interventions have been previously shown to improve health outcomes among non-Hispanic White breast cancer populations. This pilot study aimed to test the cultural sensitivity, feasibility, and potential health benefits of an expressive writing intervention among Chinese-speaking breast cancer survivors. METHODS: Participants (N = 19) were asked to write about their deepest thoughts and feelings, their coping efforts, and positive thoughts and feelings regarding their experience with breast cancer each week for 3 weeks. Health outcomes were assessed at baseline, 3, and 6 months after the intervention. A Community-Based Participatory Research Approach (CBPR) is used. RESULTS: Expressive writing was associated with medium and large effect sizes (η(p)² = 0.066∼0.208) in improving multiple health outcomes (quality of life, fatigue, posttraumatic stress, intrusive thoughts, and positive affect) at follow-ups. Participants perceived the study to be valuable. The study yielded high compliance and completion rates. CONCLUSION: Expressive writing is associated with long-term improvement of health outcomes among Chinese breast cancer survivors and has the potential to be utilized as a support strategy for minority cancer survivors. In addition, CBPR is valuable in improving feasibility and cultural sensitivity of the intervention in understudied populations. Future studies employing randomized, controlled trial designs are warranted.
