Perceived social support and self-stigma as factors of COVID-19 booster vaccination behavior and intention via cognitive coping and emotion regulation among people infected with COVID-19 in Hong Kong.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIt is imperative to promote behavior/intention of taking up booster COVID-19 vaccination (BI-BV) among people who have ever contracted COVID-19 (PECC). The aims were to investigate the prevalence of BI-BV and its associations with perceived social support. Guided by the stress coping theory, we tested mediators between perceived social support and BI-BV via self-stigma, active coping, and maladaptive emotion regulation (rumination and catastrophizing).
methodsA random population-based telephone survey was conducted among adult PECC having completed the primary series of COVID-19 vaccination prior to the diagnosis; 230 participants were interviewed from June to August 2022 during the fifth (last) major outbreak in Hong Kong. The associations between the independent variables and BI-BV were tested by logistic regression analysis. A structural equation model (SEM) tested the indirect effects of the latent variables of self-stigma, active coping, and maladaptive emotion regulation between the latent variable of perceived social support and BI-BV.
resultsThe prevalence of BI-BV was 62.2%. It was associated with age, marital status, full-time employment, and chronic disease status. The logistic regression analysis found that BI-BV was positively associated with perceived social support (ORc = 1.31, 95% CI: 1.12- 1.54), active coping (ORc = 1.40, 95% CI: 1.10- 1.79), rumination (ORc = 1.75, 95% CI: 1.13- 2.70), and catastrophizing (ORc = 3.12, 95% CI: 1.49- 6.51) and negatively associated with self-stigma (ORc = 0.80, 95% CI: 0.72- 0.88). In the SEM analysis, the positive association between perceived social support and BI-BV was fully mediated: 1) via self-stigma (β = 0.07, 95% CI: 0.03- 0.14), 2) via active coping (β = 0.06, 95% CI: 0.02- 0.12), and 3) via self-stigma and then active coping (β = 0.01, 95% CI: 0.002- 0.04). Two of these indirect paths involved active coping. The indirect paths involving maladaptive emotion regulation were all non-significant.
conclusionsPerceived social support was associated with BI-BV, and was mediated via self-stigma, active coping, and serially self-stigma then active coping but not emotion maladaptation. The data supported the stress cognitive coping model in explaining the association between perceived social support and BI-BV. Interventions promoting BI-BV may consider modifying the observed significant factors. Future longitudinal studies are warranted to confirm the findings.
