Structural equation modeling of the effect of childhood trauma on premenstrual syndrome: the mediating role of rumination in adolescent girls.

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
Premenstrual syndrome (PMS) is a common adolescent disorder characterized by emotional, behavioral, and physical symptoms that impair quality of life. Psychological factors, particularly childhood trauma, may influence PMS severity. This study examined the associations between childhood trauma and PMS, with rumination as a potential mediating variable, using structural equation modeling (SEM). A descriptive-analytical SEM design was conducted with 384 high school girls in Saqqez, Iran (2023-2024), selected via multistage cluster sampling. Data were collected using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), Ruminative Responses Scale (RRS), and Premenstrual Symptoms Screening Tool (PSST). Analyses were performed in AMOS 26. Childhood trauma had significant direct effects on PMS (β = 0.52, p < 0.001) and rumination (β = 0.48, p < 0.001). Rumination directly influenced PMS (β = 0.42, p < 0.001) and mediated the relationship between trauma and PMS (indirect β = 0.20, p < 0.001). The model demonstrated acceptable fit indices. Childhood trauma and rumination are key contributors to PMS severity in adolescent girls. Early detection of these factors and development of targeted psychological interventions are crucial for promoting mental health in this population.
