Levels and factors derived from the Health Action Process Approach of behavioral intentions to take up COVID-19 vaccination: A random population-based study.

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
objectivesCOVID-19 vaccination needs a high population coverage to achieve herd immunity. We investigated prevalence of three scenarios of intention of free COVID-19 vaccination involving: 1) 80% effectiveness and rare and mild side effects (Scenario 1), 2) 50% effectiveness and rare and mild side effect RMSE (Scenario 2), and 3) immediate vaccination (Scenario 3), and their associated factors derived from the pre-intentional motivational phase of the Health Action Process Approach (HAPA).
methodsA random population-based telephone survey interviewed 450 Chinese adults in the general population (September 16-30, 2020). The four HAPA constructs included a) risk perception scale, b) overall scale/four subscales of positive outcome expectancy of COVID-19 vaccination, c) overall scale/three subscales of negative outcome expectancy of COVID-19 vaccination, and d) the overall scale/two subscales of self-efficacy of COVID-19 vaccination.
resultsThe prevalence of intention of COVID-19 vaccination under Scenarios 1 to 3 was 38.0%, 11.1%, and 13.1%, respectively. Logistic regression analyses adjusted for background factors showed that 1) the associations between risk perception and the three scenarios of intention were non-significant; 2) the overall scale/four subscales of positive outcome expectancy were in general positively associated with two scenarios of intention (80% effectiveness and immediate vaccination); 3) the overall scale/three subscales of negative outcome expectancy were in general negatively associated with all three scenarios of intention; 4) the overall scale/two subscales of self-efficacy were only positively associated with the intention that involved 80% effectiveness. When all the four overall scales were entered into an adjusted model, positive and negative outcome expectancy, but not risk perception and self-efficacy, were independently associated with the three scenarios.
conclusionsIn this study population, the prevalence of intention of COVID-19 vaccination was very low and might not result in population protection. Health promotion should modify outcome expectancies to increase intention of COVID-19 vaccination.
