With the growing older population, ensuring effective, accessible nutritional support within primary care as a first line of medical care is becoming increasingly important. Nutritional counselling is a promising approach to enhancing health outcomes and independence among older adults. However, a stronger evidence base is needed to assess its true effect and inform clinical decisions. Additionally, food insecurity remains an under-recognised issue in this population and is often overlooked in primary care settings. This highlights the need for simple, practical methods to identify those at risk. This study aimed to assess the effectiveness of nutritional intervention provided to older people and determine which nutrients may indicate food insecurity in primary care settings in Tehran.

The study will be conducted in two phases. The first phase is a prospective cohort study (single cohort). The second phase is a cross-sectional study on older people who refer to primary care settings affiliated with the Tehran University of Medical Sciences. In the first phase, the effectiveness of nutritional interventions – including counselling and diet – is evaluated based on anthropometric indicators (weight, waist circumference, calf circumference, arm circumference and waist-to-height ratio), blood pressure and scores from the Mini Nutritional Assessment, health-related quality of life, dietary intake and physical activity. Assessments will be evaluated prospectively at the beginning of the study, after 3 months, and at the end of the study. In the second phase of the cross-sectional study, by examining dietary intake and food insecurity, we will identify the specific nutrient or food group that serves as an indicator of food insecurity in the diet of older individuals. Intakes below 50% and 75% of the recommended daily allowance will be analysed. Through sensitivity and specificity analysis, we will identify which nutrient or food group is strongly associated with food insecurity in older people.

This study received approval from the Medical Ethics Committee of Tehran University of Medical Sciences, Tehran, Iran (IR.TUMS.MEDICINE.REC.1402.474). Study findings will be disseminated through peer-reviewed journal articles, presentations at national and international conferences and meetings with the Iranian Ministry of Health, facility and community stakeholders.

Child-to-parent violence (CPV) has received limited attention in scientific literature, but due to a recent increase in reported cases, it has become a subject of investigation. The reliability and validity of the Child-to-Parent Violence Questionnaire (CPV-Q), in separate mother and father versions, have not yet been studied in Iran. This study aimed to assess the psychometric properties of the Persian CPV-Q.

This research employed a cross-sectional design to evaluate the Persian CPV-Q’s psychometric properties. The process included translation (using backward-forward method), face validity (via impact score calculation), content validity (using content validity ratio (CVR) and content validity index (CVI)), construct validity (through exploratory and confirmatory factor analyses (CFA)) and reliability assessment (via test–retest, coefficient α, coefficient and intraclass correlation coefficient (ICC)).

The study was conducted at the Faculties of Tabriz University of Medical Sciences.

A total of 500 qualified students from Tabriz University of Medical Sciences were recruited using cluster random sampling. These participants completed the Persian CPV-Q.

Face validity was confirmed, with impact scores exceeding 1.5 for all items. Content validity was strong, with CVR=0.92 and CVI=0.89. Exploratory factor analysis revealed four factors related to violence frequency and two factors regarding reasons for violence, consistent with the original questionnaire, covering 19 and 8 items, respectively. Total variance explained was 0.30 and 0.39 for the mother’s version and 0.33 and 0.43 for the father’s version in frequency and reason sections. The Kaiser-Meyer-Olkin test confirmed sample adequacy (

The Persian CPV-Q demonstrates adequate validity and reliability for assessing the prevalence and causes of CPV in Iranian society.

Primary care nurses (PCNs) are the second largest workforce in primary care and play a critical role in facilitating access to coordinated care and reducing health disparities. There is renewed interest in team-based primary care as a solution for health workforce challenges. Some team models enable PCNs (ie, nurse practitioners, registered nurses, licensed/registered practical nurses) to leverage one another’s expertise to work to optimal scope; the extent to which this happens depends on multiple context-dependent factors. We will conduct an umbrella review to synthesise and compare international knowledge syntheses focused on scope of practice enactment (ie., roles and activities) of PCNs in primary care.

We will conduct the umbrella review according to the Joanna Briggs Institute methodology, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) guidelines, and using the Nursing Care Organization Framework as guidance. We will search a wide range of scientific electronic databases and grey literature sources, and consider articles published in English and French by the Organization for Economic Cooperation and Development and designated key partner countries for inclusion, with no publication date limits. Two independent reviewers will screen titles, abstracts and full-text articles, and any disagreements will be resolved through discussion or by a third reviewer. We will use the Risk of Bias Assessment Tool for Systematic Reviews to assess the quality and risk of bias in the included systematic and scoping reviews.

Results will be presented in a PRISMA Scoping Review flow diagram. We will synthesise data from included studies in a detailed literature review table and develop visual aids to communicate the shared and unique roles and activities of PCN scope of practice. We will disseminate the results of the review through peer-reviewed publications and conferences related to this field. Ethics approval is not required.
