Validity and reliability of the Turkish version of the revised illness perception questionnaire for oral health (IPQ-R-OH) in patients with dental caries.
Article in BMC oral health, 2025. 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
backgroundDental caries is a common oral disease with significant implications for oral health. To develop effective interventions, assessing oral health perceptions in the Turkish population is essential. Despite this, there is currently no validated Turkish version of the Revised Illness Perception Questionnaire for Oral Health (IPQ-R-OH). The purpose of this study is to perform validity and reliability analyses on the Turkish version of the IPQ-R-OH.
methodsA cross-sectional design was employed, and data were collected between September and November 2022 at the Faculty of Dentistry, Recep Tayyip Erdogan University. Participants aged 18-65 were recruited using a convenience sampling method. Individuals who were literate, systemically healthy, and not pregnant or lactating were included. Following a standardized clinical oral examination based on WHO criteria, eligible participants completed a structured questionnaire that included socio-demographic and clinical variables along with the IPQ-R-OH.
resultsA total of 440 participants (54.8% women; mean age = 31.1 years) were included in the analysis. Exploratory factor analysis (EFA) led to the removal of six items, resulting in a 30-item, seven-factor structure explaining 59.5% of the total variance. Internal consistency coefficients (Cronbach's alpha) ranged from 0.58 to 0.86 across the factors. Confirmatory factor analysis (CFA) supported the construct validity of the revised model, with acceptable fit indices (RMSEA = 0.060, NFI = 0.900, CFI = 0.901, and χ²/df = 2.573).
conclusionsThe translated version of IPQ-R-OH was found to be valid and reliable for the Turkish population. The Turkish version of IPQ-R-OH is appropriate for patients with dental caries to evaluate their perceptions of the disease, their expectations from treatment, and their psychometric properties.
