Assessing interpersonal violence involvement in psychiatric patients: exploratory findings on the Interpersonal Violence Questionnaire (IVIQ).
Article in BMC psychiatry, 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
backgroundDespite the high rates of both violence victimization and perpetration in people experiencing mental illness, standardized screening tools in research and for routine psychiatric assessment are lacking, underscoring the need for feasible, standardized assessment approaches.
methodsA sample of adult psychiatric in- and out-patients at six German hospitals was surveyed, using the Interpersonal Violence Questionnaire (IVIQ), a 26-item self-report checklist assessing experiences of physical violence, sexual violence, and threats, both as victimization and perpetration, across the past 12 months and lifetime. Exploratory analyses included prevalence estimates, scoring characteristics, floor effects, inter-item associations, temporal stability, and associations with social desirability.
resultsIn 479 patients, lifetime sexual victimization and 12-month violence threat, as well as being pushed, were most frequent. IVIQ sum scores showed strong floor effects. Reports of victimization and perpetration frequently co-occurred; descriptive inter-item correlations were low to moderate. Temporal consistency varied across items, with lower stability for low-prevalence behaviors. Higher social desirability predicted lower 12-month perpetration reporting.
conclusionsThe IVIQ may provide a feasible, structured self-report approach for routine assessment of interpersonal violence involvement in psychiatric populations. Different scoring approaches may support descriptive assessment of cumulative burden and distinct forms of interpersonal violence involvement. Future versions should broaden the assessment of psychological violence. Associations between social desirability and reporting underline the importance of sensitive implementation, trauma-informed assessment practices, and cautious interpretation of self-reported violence experiences.
