Changing Mindsets About Side Effects of the COVID-19 Vaccination: A Randomized Controlled Trial.

BACKGROUND: Side-effect concerns are a major barrier to vaccination against COVID-19 and other diseases. Identifying cost- and time-efficient interventions to improve vaccine experience and reduce vaccine hesitancy-without withholding information about side effects-is critical. PURPOSE: Determine whether a brief symptom as positive signals mindset intervention can improve vaccine experience and reduce vaccine hesitancy after the COVID-19 vaccination. METHODS: English-speaking adults (18+) were recruited during the 15-min wait period after receiving their second dose of the Pfizer COVID-19 vaccination and were randomly allocated to the symptom as positive signals mindset condition or the treatment as usual control. Participants in the mindset intervention viewed a 3:43-min video explaining how the body responds to vaccinations and how common side effects such as fatigue, sore arm, and fever are signs that the vaccination is helping the body boost immunity. The control group received standard vaccination center information. RESULTS: Mindset participants (N = 260) versus controls (N = 268) reported significantly less worry about symptoms at day 3 [t(506)=2.60, p=.01, d=0.23], fewer symptoms immediately following the vaccine [t(484)=2.75, p=.006, d=0.24], and increased intentions to vaccinate against viruses like COVID-19 in the future [t(514)=-2.57, p=.01, d=0.22]. No significant differences for side-effect frequency at day 3, coping, or impact. CONCLUSIONS: This study supports the use of a brief video aimed at reframing symptoms as positive signals to reduce worry and increase future vaccine intentions.

Side-effect concerns are a major barrier to vaccination against COVID-19 and other diseases. Therefore, the purpose of this study was to determine whether a brief symptom as positive signals mindset intervention could improve vaccine experience and reduce vaccine hesitancy after the COVID-19 vaccination. Participants were recruited during the 15-min wait period after receiving their second dose of the Pfizer COVID-19 vaccination and were randomly allocated to a treatment as usual control condition or to a mindset intervention condition which entailed watching a 3:43-min video explaining how the body responds to vaccinations and how common side effects such as fatigue, sore arm, and fever are signs that the vaccination is helping the body boost immunity. Compared with participants in the control condition, participants in the mindset intervention condition reported significantly less worry about symptoms at day 3, fewer symptoms immediately following the vaccine and increased intentions to vaccinate against viruses like COVID-19 in the future. No significant differences emerged for side-effect frequency at day 3, coping, or impact. These finding provide initial support for cost- and time-efficient interventions to improve vaccine experience and reduce vaccine hesitancy without withholding information about side effects.Keywords: Vaccination ∙ Mindset ∙ COVID-19 ∙ Health Communication ∙ Symptoms.

Changes in mental health problems and suicidal behaviour in students and their associations with COVID-19-related restrictions in Norway: a national repeated cross-sectional analysis.

OBJECTIVE: The COVID-19 pandemic has had a devastating impact on higher education, with the closure of student campuses. The aim of this study was to examine changes and prevalence of mental health problems, suicidal ideation and suicidal behaviour, and their associations with COVID-19-related restrictions. DESIGN, SETTING AND PARTICIPANTS: As part of the SHoT-study in Norway, 62 498 students completed an online questionnaire (65.6% women; response rate of 34.4%) in March 2021. Data were compared with previous waves, conducted in 2018, 2014 and 2010. PRIMARY AND SECONDARY OUTCOME MEASURES: Mental health problems were assessed using the Hopkins Symptoms Checklist. Suicidal ideation, suicide attempts and non-suicidal self-harm (NSSH) were assessed with three items drawn from the Adult Psychiatric Morbidity Survey, and thoughts of NSSH were assessed with one item from the Child and Adolescent Self-Harm in Europe study. RESULTS: There was a significant increase in mental health problems from 2010 to 2021, and especially from 2018 (men: 27%/women: 45%) to 2021 (men: 41%/women: 62%, p <0.001). A similar pattern was also observed for suicidal thoughts. Unlike previous waves, there were large geographical differences in mental health problems in 2021, which mapped onto the different levels of COVID-19 cases and regional COVID-19-related restrictions. There was a significant negative dose-response association between days spent physically on campus and both mental health problems and indicators of suicide risk. We found the fewer days spent on campus in the last 2 weeks, the higher levels of mental health problems during the same time period. There was also an association between days on campus and a higher prevalence of suicidal thoughts, NSSH and suicide attempts in the last year. CONCLUSION: This study demonstrates a sharp increase and disturbing levels of mental health problems and suicide risk among students during the COVID-19 pandemic. Although causal conclusions cannot be drawn, the associations between closure of campuses and mental problems emphasise the importance of having access to campuses for student well-being.
