RESUMEN
OBJECTIVES: This study aimed to examine the psychometric properties of the P4 suicide screener in a multinational sample. The primary goal was to evaluate the reliability and validity of the scale and investigate its convergent validity by analyzing its correlation with depression, anxiety, and substance use. STUDY DESIGN: The study design is a cross-sectional self-report study conducted across 42 countries. METHODS: A cross-sectional, self-report study was conducted in 42 countries, with a total of 82,243 participants included in the final data set. RESULTS: The study provides an overview of suicide ideation rates across 42 countries and confirms the structural validity of the P4 screener. The findings indicated that sexual and gender minority individuals exhibited higher rates of suicidal ideation. The P4 screener showed adequate reliability, convergence, and discriminant validity, and a cutoff score of 1 is recommended to identify individuals at risk of suicidal behavior. CONCLUSIONS: The study supports the reliability and validity of the P4 suicide screener across 42 diverse countries, highlighting the importance of using a cross-cultural suicide risk assessment to standardize the identification of high-risk individuals and tailoring culturally sensitive suicide prevention strategies.

UNLABELLED: This paper outlines the topics that are on the intersection of neuroethics and neuroimaging domain. MATERIALS AND METHODS: An extensive search through Medline bibliographic database was performed for a period of 12 years (1997-2009), using a combination of 3 keywords ("ethics", "neuroethics", "neuroimaging"). The search returned 119 indexed articles, of which 102 were found relevant. The articles were classified in two main categories tackling ethical challenges in basic research (55 papers) and applied clinical research and practice (39 papers). RESULTS AND CONCLUSIONS: For each of the categories, the majority of articles came under one of the following topics--the neural basis of emotion, reasoning and personality (30 papers) and ethics of neuroimaging in disorders of consciousness (15 papers). The appointed topics stand at the very intersection of the neuroethics and neuroimaging domain, evidencing their strong interdependent relationship. Furthermore, the number of topics and corresponding articles has been steadily increasing over the years (minimal in 1997, maximal in 2009). These data are in good acconcordance with other scientific findings. Also, they correspond to the period of progress in the investigated disciplines, giving rise to the fact that future advances in neuroethics are in strong correlation to the advances of neuroimaging technologies.
