1 · What the graph read from it

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.

2 · The registry

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

purposeA much higher prevalence of alexithymia has been found in medical students compared with the general population. This study aimed to test the potential mediating effect of psychological capital on the relationship between childhood trauma and alexithymia in Chinese medical students, thereby providing clues for future interventions aimed at dealing with alexithymia in this population.

methodsConvenience cluster sampling was used to recruit 1200 medical students in Chongqing, China. This cross-sectional study utilised the Childhood Trauma Questionnaire Short Form, the Toronto Alexithymia Scale, and the Psychological Capital Questionnaire. A structural equation model with maximum likelihood was used to study the mediating effect presented in the aim, and the significance of the mediating effect was examined by the bootstrap method. Multiple-group invariance analyses were also conducted to confirm the stability of the model.

resultsA total of 1018 were identified to have valid responses with a rate of 84.83%. 38.4% were males, 61.6% were females. The prevalence of alexithymia was 16.5%. Results of structural equation model showed that childhood trauma was positively related to alexithymia, with a standard path coefficient of 0.219 (C.R.=6.644, P<0.001). The partial mediating effect of psychological capital was 0.060 (P<0.001), accounting for 21.51% of the total effect of childhood trauma on alexithymia. Results of bootstrap method showed that the lower and upper bounds of the 95% confidence interval did not contain 0, and the multiple-group invariance analyses showed that the p values of the changes in the degrees of freedom and chi-square value were greater than 0.05, thus confirming the stability of the model.

conclusionChildhood trauma was a direct predictor of alexithymia among Chinese medical students, and the relationship between these two was partially mediated by psychological capital. Therefore, interventions aimed at enhancing psychological capital in this population may be effective at diminishing alexithymia.
