Interpersonal psychological needs as mediators linking abusive supervision and concurrent suicidal ideation: mediation analysis using parallel-process latent growth models based on a diary 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
backgroundGiven the frequent suicides among graduate students resulting from strained student-teacher relationships, we delved into the concurrent influence of abusive supervision on suicidal ideation among graduate students. Furthermore, we examined the potential mediating roles of the evolving trajectories of interpersonal psychological needs (thwarted belongingness and perceived burdensomeness) in this complex relationship.
methodsA diary study was conducted, involving 105 graduate students who had reported experiencing abusive supervision. Participants completed self-report surveys at twelve time points, assessing perceptions of daily abusive supervision, thwarted belongingness, perceived burdensomeness, as well as the presence of suicidal ideation. The study yielded 1,074 valid responses for analysis.
resultsEmploying a parallel-process latent growth model, we found that suicidal ideation exhibited parallel development with with abusive supervision, in both initial level (β = 0.714, p < 0.001) and growth rate (β = 0.618, p < 0.001). To investigate the underlying mechanisms, the latent growth curve mediation models were adopted to examine the potential mediating roles of interpersonal psychological needs. Specifically, initial levels of thwarted belongingness (β = 0.240, p < 0.001) and perceived burdensomeness (β = 0.362, p < 0.001) mediated the relationship between the initial levels of abusive supervision and suicidal ideation. However, only the growth rate of perceived burdensomeness showed marginal mediation (β = 0.027, p = 0.069) in the relationship between the growth rates abusive supervision and suicidal ideation.
conclusionDaily abusive supervision significantly predicts concurrent suicidal ideation and this association is mediated by perceived burdensomeness. These findings highlight the importance of both fostering positive and supportive supervisory relationships, and addressing unmet interpersonal psychological needs to prevent and mitigate the adverse mental health consequences of abusive supervision.
