Extensive media coverage and potential controversy about COVID-19 vaccination during the pandemic may have affected people's general attitudes towards vaccination. We sought to describe key psychological antecedents related to vaccination and assess how these vary temporally in relationship to the pandemic and availability of COVID-19 vaccination. As part of an ongoing online study, we recruited a national (U.S.) sample of young gay, bisexual and other men who have sex with men (N = 1,227) between October 2019 and June 2021, and assessed the "4Cs" (antecedents of vaccination; range = 1–5). Overall, men had high levels of confidence (trust in vaccines; M = 4.13), calculation (deliberation; M = 3.97) and collective responsibility (protecting others; M = 4.05) and low levels of complacency (not perceiving disease risk; M = 1.72). In multivariable analyses, confidence and collective responsibility varied relative to the pandemic phase/vaccine availability, reflecting greater hesitancy during later stages of the pandemic. Antecedents also varied by demographic characteristics. Findings suggest negative effects of the COVID-19 pandemic on key antecedents of general vaccination and identify potential targets for interventions. [ABSTRACT FROM AUTHOR]

Objectives: Publicity on incidents of electronic nicotine delivery systems (ENDS) exploding or catching fire may influence smokers' risk perceptions and decisions about using ENDS for quitting smoking. We examined combustible cigarette smokers' perceptions of the possibility of injury from exploding ENDS and the relationship of those perceptions to ENDS use, perceived risk relative to smoking, and perceived costs and benefits of ENDS use. Methods: We used data from the 2017 Tobacco Products and Risk Perceptions Survey of a national probability sample of US adults, conducted online in August and September 2017. The analytic sample consisted of 1181 current combustible cigarette smokers aware of ENDS. Results: Among combustible cigarette smokers aware of ENDS, a medium/high perceived risk of injury from exploding ENDS was associated with lower odds of current ENDS use (adjusted odds ratio [aOR] = 0.50; 95% confidence interval [CI], 0.30-0.86; P =.01), perceiving ENDS to be at least as harmful as cigarettes (aOR = 3.22; 95% CI, 2.11-4.93; P <.001), and feeling that the negatives of ENDS use outweighed the positives (aOR = 3.50; 95% CI, 2.00-6.14; P <.001). Conclusions: Product standards, improved product labeling, and education about how to properly use, charge, and store ENDS can help protect consumers from injury. Communication efforts should seek to fully inform combustible cigarette smokers about both the absolute health risks of ENDS, including risk of explosions, and their relative risks compared with those of cigarette smoking.

Background older people coping with the impacts of living with multimorbidity are at increased risk of developing a depressive disorder. Objective this article reports the 24-month results of a randomised controlled trial of an internet-delivered cognitive behaviour therapy, which aimed to test whether depressive disorders could be prevented in this population. Participants community-based participants aged 65 years and over, who had two or more chronic physical health conditions and were assessed as having no current depressive disorder. Methods in total, 302 participants were randomised to an 8-week, five-lesson, internet-delivered intervention program (n  = 150) or treatment as usual (TAU, n  = 152). The primary outcomes were cases of depressive disorder, assessed post-intervention and at 3-month intervals throughout the trial, and depressive symptoms, assessed at pre-intervention, post-intervention, 6, 12 and 24 months following the intervention. Results there were significantly fewer cases of depressive disorder in the intervention group (n  = 23, 15%) compared with the TAU group (n  = 41, 27%) during the 24 months after the intervention (χ2(1, N  = 302) = 6.13, P  = 0.013, odds ratio = 0.490 [95% confidence interval: 0.277, 0.867]), representing a 44% reduction in cases of depressive disorder. No differences were found on depressive symptoms at 24-month follow-up. Internet-delivered cognitive behaviour therapy had high engagement and acceptability. Conclusions the results provide support that depressive disorders can be prevented in older people with multimorbidity through participation in internet-delivered cognitive behaviour therapy. With access to internet-delivered interventions in clinical care settings increasing, this has implications for older patient care where multimorbidity is extremely common. [ABSTRACT FROM AUTHOR]
