Spiritual well-being is a recognized predictor of health-related quality of life in palliative patients. No research in Croatia has yet addressed this field. This study, the first of its kind in Croatia, validated a Croatian translation of the EORTC QLQ-SWB32 measure of spiritual well-being with curative Croatian oncology patients and assessed its use and value. The study was conducted between July 2019 and January 2020 at the Department of Radiotherapy and Oncology, University Hospital Rijeka, with 143 cancer patients, using the linguistically validated Croatian version of the measure. All patients found the measure acceptable. Confirmatory factor analysis aligned with the structure found in previous studies. Cronbach’s alpha confirmed internal consistency. Female participants scored higher on the RSG (Relationship with Someone or Something Greater), RG (Relationship with God), and EX (Existential) scales, and on Global-SWB. Patients with breast and gynecological tumors scored higher on RG. Older patients scored lower on RSG, RG and EX. Retirees and those with below-average incomes scored lower on EX. Participants who identified as having no religion scored lower on RSG. Stage I cancer patients scored higher on RG. The Croatian version of the EORTC QLQ-SWB32 is an acceptable, valid, and reliable measure of SWB for Croatian cancer patients.

Oral health during pregnancy is a critical factor in preventing caries in both mothers and children. Croatia currently lacks validated psychometric instruments for reliably as-sessing knowledge, attitudes, and oral hygiene practices in the general population. This study aimed to develop and validate a comprehensive instrument for this purpose in Cro-atia and internationally. Following Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines, an initial item pool was generated through literature review and expert consultation. The study was conducted from May 2024 to February 2025 in primary healthcare settings across Primorje-Gorski Kotar County (PGC). The validation study included 319 pregnant women. Exploratory factor analysis (EFA) revealed a six-factor structure with acceptable to strong factor loadings (ranging from 0.423 to 0.984). The instrument showed acceptable to good internal consistency (Cronbach’s α = 0.61–0.87) and excellent test–retest reliability (Pearson r = 0.993). Results indicated that knowledge about oral health was independent of attitudes and practices during pregnancy, while regression analysis suggested that pregnant women's behaviors are influenced by complex factors beyond those captured in the initial study model. This newly developed and validated questionnaire is a reliable public health tool for systematic data collection, supporting targeted educational interventions to prevent caries and pro-mote oral health among pregnant women.

Oral health during pregnancy is a critical factor in preventing caries in both mothers and children. Croatia currently lacks validated psychometric instruments for reliably assessing knowledge, attitudes, and oral hygiene practices in the general population. This study aimed to develop and provide initial psychometric evidence for a comprehensive instrument for this purpose in Croatia, with potential relevance for future cross-cultural adaptation.

Results indicated that knowledge about oral health was independent of attitudes and practices during pregnancy. Regression analyses were exploratory and did not provide evidence of predictive validity at this stage, suggesting that additional contextual and psychosocial factors should be considered in future modelling. The present study provides initial psychometric evidence supporting the proposed structure and reliability of the instrument; however, further confirmatory and longitudinal validation studies are required before broader implementation and generalization can be fully justified.
