Name-based instructor-student interaction in medical teaching: development and psychometric evaluation of a pilot questionnaire.

PURPOSE: When instructors address students by name, this may be associated with students' engagement and sense of inclusion in higher education. However, name-based instructor-student interaction has rarely been conceptualized as a multidimensional construct, and no psychometrically evaluated instrument is available for medical education. This study developed and psychometrically evaluated a pilot questionnaire assessing students' perceived experiences of being addressed by name in medical teaching contexts. METHODS: Questionnaire development followed a multistep exploratory approach that inc

Translation, cultural adaptation, and validation of the Vietnamese Child Perceptions Questionnaire (CPQ8-10VN) for children aged 8-10 years.

PURPOSE: This study aimed to translate, culturally adapt, and validate the Vietnamese version of the Child Perceptions Questionnaire 8-10 (CPQ8-10VN) for assessing oral health-related quality of life (OHRQoL) in Vietnamese children aged 8-10 years. METHODS: Following forward-backward translation with cognitive pre-testing (n = 15), in this cross-sectional validation study conducted in an elementary school in Hue City, 234 children aged 8-10 years (mean age 9.1 ± 0.8 years; 50% boys) completed the CPQ8-10VN and underwent oral examinations for caries and oral hygiene. A subsample of 37 9-year-o

'Things You Do' and Mental Health in Turkish Adolescents and Adults: Validation of the Turkish Version of Things You Do Questionnaire-15 Item.

This study aimed to examine the reliability and validity of a Turkish version of the Things You Do Questionnaire-15 item (TYDQ-15). Data was collected from three samples. Sample 1 comprised 245 adolescents and adults aged 14 to 47 years (Mage= 16.62, SDage= 2.99), who were recruited to confirm the factor structure of the TYDQ-15 using confirmatory factor analysis (CFA) and item analysis. Sample 2 comprised 552 adolescents and adults aged 14 to 47 years (Mage=22.96, SDage=10.14). Sample 2 completed translated and validated versions of measures of depression (Patient Health Questionnaire-9 Item)

Translation, cross-cultural adaptation, and validation of the Caregiver Indirect and Informal Care Cost Assessment Questionnaire for end-of-life care into Spanish.

OBJECTIVE: This study aims to adapt and validate a Spanish (Argentina) version of the Caregiver Indirect and Informal Care Cost Assessment Questionnaire (CIIQ) to enable the measurement of informal care-related costs in the Argentine context, addressing the current lack of Spanish-language tools for assessing indirect costs. METHOD: The CIIQ was translated, cross-culturally adapted, and validated for the Spanish-Argentine language and culture. Psychometric properties were evaluated in a purposive sample of relatives of patients with advanced chronic disease and limited life expectancy in Arge

Development and Validation of a Measure of Psychological Distress After Spontaneous Coronary Artery Dissection: The Spontaneous Coronary Artery Dissection Distress Inventory.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a highly distressing cause of acute myocardial infarction. No SCAD-specific distress measure currently exists, with researchers relying on generic measures of anxiety, depression, and distress that fail to capture the psychological impacts unique to SCAD. We developed and validated the SCAD Distress Inventory (SDI) to provide a condition-specific distress measure. METHODS: The SDI was developed through a multistep process. First, 48 SCAD-related distress items were generated from focus groups with SCAD survivors (N=30) and relevant

Assessment of childbirth-related post traumatic stress disorder in Australian mothers: Psychometric properties of the City Birth Trauma Scale.

BACKGROUND: The City Birth Trauma Scale (BiTS; Ayers, Wright & Thornton, 2018) is self-report measure of Post-Traumatic Stress Disorder (PTSD) symptoms following childbirth, based on DSM-5 criteria. We report on the first study of the psychometric properties of the BiTS in the Australian population. METHODS: Participants were mothers of infants aged 0-12 months (N = 705), who completed the BiTS and measures of related constructs. Confirmatory factor analysis was performed to assess the factor structure of the BiTS. Examination of the reliability, convergent, divergent and discriminant validit

Probing the clinical and brain structural boundaries of bipolar and major depressive disorder.

Bipolar disorder (BD) and major depressive disorder (MDD) have both common and distinct clinical features, that pose both conceptual challenges in terms of their diagnostic boundaries and practical difficulties in optimizing treatment. Multivariate machine learning techniques offer new avenues for exploring these boundaries based on clinical neuroanatomical features. Brain structural data were obtained at 3 T from a sample of 90 patients with BD, 189 patients with MDD, and 162 healthy individuals. We applied sparse partial least squares discriminant analysis (s-PLS-DA) to identify clinical and…

The Primary Aldosteronism Surgical Outcome Score for the Prediction of Clinical Outcomes After Adrenalectomy for Unilateral Primary Aldosteronism.

OBJECTIVE: To develop a prediction model for clinical outcomes after unilateral adrenalectomy for unilateral primary aldosteronism. SUMMARY BACKGROUND DATA: Unilateral primary aldosteronism is the most common surgically curable form of endocrine hypertension. Surgical resection of the dominant overactive adrenal in unilateral primary aldosteronism results in complete clinical success with resolution of hypertension without antihypertensive medication in less than half of patients with a wide between-center variability. METHODS: A linear discriminant analysis model was built using data of 380…

Chloride sources in urban and rural headwater catchments, central New York.

Road salt used as a deicing agent in winter months has become an emerging contaminant to streams and groundwater. In central New York, road … ioga River, using two independent approaches: (1) chloride to bromide ratios (Cl/Br) and (2) linear discriminant analysis. Ratios of Cl/Br suggest that road salt runoff influence is notable in both branches, but is more significant in the West Branch, consistent with a greater area of urban land. Linear discriminant analysis confirms the results of Cl/Br in the West Br …
