Bidirectional predictive modeling of narcissists' social exclusion and their hostile interpretations: a deep learning-based exploration of cognitive mechanisms.

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
This study aimed to clarify the interaction mechanism among hostile interpretation, narcissistic personality traits, and social exclusion/acceptance situations, address the limitation of traditional linear analysis, construct an accurate "trait-situation-cognition" prediction model (Hostile Interpretation & Bidirectional Prediction Network, HIBPN), and verify the intervention effect of self-affirmation on social exclusion. Two sequential experiments were designed: Experiment 1 enrolled undergraduate and postgraduate students, divided them by narcissistic traits into dominant narcissism, implicit narcissism, and neutral control groups, manipulated situations via Cyberball 5.0, quantified hostile interpretation biases, and validated situational effectiveness to provide modeling data. Experiment 2 selected implicit narcissists from Experiment 1, randomly assigning them to the self-affirmation intervention group (completing a value- and trait-oriented self-affirmation task) and control group (completing a neutral task). Consistent manipulation and tools with Experiment 1 were used to verify the intervention effect. The model integrated situational variables and narcissistic traits, establishing a closed-loop "antecedent-social exclusion-cognition" system and a bidirectional inference structure (the forward chain predicts social exclusion probability, and the reverse chain deduces the path of hostile interpretation bias). Results: In Experiment 1, under the 1:9 training-test set ratio, the predictive efficacies of the model's two paths reached 69.9 and 83.2%, confirming significant interactions among the three variables; narcissistic traits accounted for 33.55 and 75.73% of the weights, serving as the core driving variable. In Experiment 2, preventive self-affirmation prior to social exclusion significantly reduced implicit narcissists' hostile interpretation bias, with their subjectively predicted social acceptance rate 5.56% higher than that of the control group. This study reveals the dynamic interaction mechanism via HIBPN, providing a new cognitive prediction framework, and confirms the intervention value of preventive self-affirmation, offering a feasible approach to maintaining mental health.
