Many Americans fail to get life-saving vaccines each year, and the availability of a vaccine for COVID-19 makes the challenge of encouraging vaccination more urgent than ever. We present a large field experiment (N = 47,306) testing 19 nudges delivered to patients via text message and designed to boost adoption of the influenza vaccine. Our findings suggest that text messages sent prior to a primary care visit can boost vaccination rates by an average of 5%. Overall, interventions performed better when they were 1) framed as reminders to get flu shots that were already reserved for the patient and 2) congruent with the sort of communications patients expected to receive from their healthcare provider (i.e., not surprising, casual, or interactive). The best-performing intervention in our study reminded patients twice to get their flu shot at their upcoming doctor’s appointment and indicated it was reserved for them. This successful script could be used as a template for campaigns to encourage the adoption of life-saving vaccines, including against COVID-19.

Family communication is a known protective factor for minor children's psychological health following the death of a parent, but there is little research describing communication within such families specifically from the perspective of the children. The purpose of this study was therefore to explore communication in parentally bereaved families from the perspective of the children and surviving parent. Methods: Interviews with four parents and four children from four families were analyzed using inductive content analysis. Interviews took place in the family's home or at the research center based on the family's wishes 4-14 months after a parent had died. Interviews had an open approach and were based on an interview guide. Each interview was between 60 and 120 min long. Results: Four categories emerged which were related to family members' experiences of family communication while adjusting to their new circumstances as bereaved: the importance of open and honest communication in the family; new challenges in the family which affect communication; communicating the need for help; and talking about and remembering the deceased parent. Conclusions: This study illuminates the connection between family communication and adjustments to new circumstances following the death of a parent. The results suggest that the relationship between family adjustment and communication may be circular whereby the family's ability to adjust to their new circumstances is affected by how the family communicates. Similarly, family communication may be affected by the family's coping strategies and ability to adjust to their new circumstances.

Parentally bereaved children and adolescents are at risk of developing psychological health problems. Evidence for a correlation between communication and broad measures of psychological health exists in other populations. The aim of this study was to examine associations between family communication and specific aspects of psychological health for children and adolescents following a parent’s death from cancer using parent-proxy and adolescent self-reports. Parent-proxy reports for children and adolescents, and adolescent self-reports for Parent–Adolescent Communication, Strengths and Difficulties Questionnaire, and Prolonged Grief-13 child were analyzed using descriptive statistics and Spearman’s correlation. Parents rated communication as moderate in quality and reported good psychological health for children and adolescents. Adolescent self-reports indicated low-quality communication with their parent and poor psychological health. Significant associations between Parent–Adolescent Communication subscales and Strengths and Difficulties Questionnaire subscales were found for each group. Prolonged grief was associated with emotional problems but not communication for all three groups.

Purpose To evaluate if nudges delivered by text message prior to an upcoming primary care visit can increase influenza vaccination rates. Design Randomized, controlled trial. Setting Two health systems in the Northeastern US between September 2020 and March 2021. Subjects 74,811 adults. Interventions Patients in the 19 intervention arms received 1-2 text messages in the 3 days preceding their appointment that varied in their format, interactivity, and content. Measures Influenza vaccination. Analysis Intention-to-treat. Results Participants had a mean (SD) age of 50.7 (16.2) years; 55.8% (41,771) were female, 70.6% (52,826) were White, and 19.0% (14,222) were Black. Among the interventions, 5 of 19 (26.3%) had a significantly greater vaccination rate than control. On average, the 19 interventions increased vaccination relative to control by 1.8 percentage points or 6.1% ( P = .005). The top performing text message described the vaccine to the patient as “reserved for you” and led to a 3.1 percentage point increase (95% CI, 1.3 to 4.9; P < .001) in vaccination relative to control. Three of the top five performing messages described the vaccine as “reserved for you.” None of the interventions performed worse than control. Conclusions Text messages encouraging vaccination and delivered prior to an upcoming appointment significantly increased influenza vaccination rates and could be a scalable approach to increase vaccination more broadly.
