Turkish UCLA PTSD-RI-5: Validation and the Role of Symptom Severity in Functional Impairment.
Article in International journal of methods in psychiatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06077474 (Validation and Reliability of the Turkish Version of the UCLA Posttraumatic Stress Disorder), which is not on this 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.

Abstract
objectivesThis study translated the UCLA PTSD Reaction Index for DSM-5 into Turkish (PTSD-RI-5-TR), evaluated its psychometric properties, and examined whether PTSD symptom severity predicts functional impairment in Turkish adolescents aged 11-17.
methodsA total of 157 trauma-exposed adolescents from a tertiary Child and Adolescent Psychiatry Clinic participated. Internal consistency and test-retest reliability were evaluated. Construct validity was examined via confirmatory factor analysis (CFA) of a five-factor model. Convergent, divergent, criterion, and known-groups validity were tested. ROC analysis assessed diagnostic accuracy. Binary logistic regression was used to evaluate the impact of scores on four functional domains.
resultsPTSD-RI-5-TR showed good internal consistency and test-retest reliability (acceptable for Category C). CFA indicated excellent fit (CMIN/DF, CFI, TLI, RMSEA) and good fit (GFI, NFI). Scores correlated strongly with NSESSS-PTSD and moderately with DES-B. PTSD diagnoses were associated with significantly higher scores. ROC analysis yielded an AUC = 0.909, sensitivity = 86.4%, specificity = 84.1% with an optimal cutoff score of 49.5. In total score models, each one-point increase predicted impairment in developmental progression (OR = 1.097), home (OR = 1.084), peer (OR = 1.071), and school functioning (OR = 1.063). In symptom cluster models, negative mood/cognition (D) most strongly predicted peer (OR = 1.205) and developmental impairment (OR = 1.155); avoidance (C) predicted home impairment (OR = 1.250); arousal/reactivity (E) predicted home (OR = 1.144) and school impairment (OR = 1.131); intrusion (B) showed no independent effect.
conclusionPTSD-RI-5-TR is a reliable, valid tool for assessing PTSD in Turkish adolescents. Higher total PTSD scores and higher scores in the C, D, and E symptom clusters may indicate a greater likelihood of functional impairment.
