Serial mediation pathways linking attachment security to loneliness: the role of self-disclosure quality and perceived social support among college students.

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
Background: Loneliness among college students has reached epidemic proportions, yet the specific behavioral and environmental mechanisms through which attachment security protects against loneliness remain unclear. While previous research has focused on how attachment insecurity contributes to loneliness, less attention has been paid to understanding the protective pathways of attachment security. This study examined a serial mediation model in which self-disclosure quality and perceived social support sequentially mediate the attachment security-loneliness relationship. Methods: A cross-sectional survey of 1,098 Chinese college students (M_age = 20.15, SD = 1.28; 82.9% female) assessed attachment security (closeness dimension), self-disclosure quality (depth and honesty composite), perceived social support, and loneliness using validated instruments. Serial mediation analysis was conducted using PROCESS Model 6 with bootstrap confidence intervals. Results: The model explained 43.2% of loneliness variance. Three significant indirect pathways emerged: perceived social support alone (B = -0.433, 69.5% of total indirect effect), complete serial mediation through self-disclosure quality and perceived social support (B = -0.110, 16.9%), and self-disclosure quality alone (B = -0.084, 13.6%). All hypothesized relationships were supported, with perceived social support serving as the dominant protective mechanism. Conclusion: Perceived social support represents the primary pathway linking attachment security to reduced loneliness, while behavioral mechanisms through self-disclosure quality provide secondary protection. These findings advance understanding of attachment security's protective mechanisms and suggest that interventions should prioritize enhancing students' capacity to recognize and utilize available social resources, with supplementary focus on developing high-quality disclosure behaviors.
