Latent profiles and characteristic networks of second victim experiences among junior nurses: a latent profile analysis and association rule mining study.
Article in BMC nursing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundJunior nurses (clinical experience ≤ 5 years) are prone to increased second victim distress after adverse events, yet the heterogeneity within this population remains poorly understood. This study used a novel combination of latent profile analysis (LPA) and association rule mining (ARM) to identify distinct second victim profiles, investigate factors associated with profile membership, and design corresponding care-bundle prototypes.
methodsA cross-sectional, STROBE-compliant survey of 387 junior nurses with ≥ 1 self-reported adverse event in the previous 12 months was conducted in three Jilin Province hospitals (provincial, municipal, county) between March and September 2025. Validated scales assessed second victim experiences, resilience, social support, coping, and personality, alongside items on adverse-event characteristics, understanding from patients' families, and institutional response. LPA identified latent subgroups; multinomial logistic regression identified factors independently associated with profile membership; ARM (Apriori algorithm) extracted multi-factor co-occurrence rules and characteristic networks.
resultsThree profiles emerged: Low Support-Low Distress (42.12%, n = 163), Moderate Support-Moderate Distress (39.28%, n = 152), Low Support-High Distress (18.60%, n = 72). Moderate Support-Moderate Distress membership was most strongly associated with monthly income < 4,500 CNY (OR = 13.254), reflecting demand-reward mismatch. Low Support-High Distress membership was independently associated with low social support (OR = 7.707), poor resilience (OR = 6.777), and lack of understanding from patients' families (OR = 5.080). For the group with the highest observed distress, ARM isolated a three-element combination, {≥10 night shifts/month + lack of understanding from patients' families + high negative coping} (confidence 0.920, lift 4.945), which may represent a candidate signal requiring validation.
conclusionsJunior nurses' second victim experiences form three heterogeneous profiles. The LPA + ARM combination identified profile-specific multi-factor co-occurrence patterns and supports person-centred early identification. Three care-bundle prototypes (high-distress stabilisation, demand-reward rebalancing, peer-mentor capacity building) provide a preliminary, data-informed framework for tiered support, pending independent validation.
