Suicide is a major public health problem worldwide with far-reaching effects on families, communities, and societies. Influencing factors range from macro-level interventions like alcohol control policies and suicide prevention programs to individual contributors such as alcohol abuse and domestic violence. This study aimed to examine the relationship between Chile's suicide rate changes from 2002 to 2015 and the Alcohol Act of 2004, a national suicide prevention program implemented in 2007, alcohol abuse, and domestic violence. Assembling a unique longitudinal dataset from Chilean public institutions, the study employed an instrumental variable time-series cross-regional design. Results indicated that the Alcohol Act was not associated with suicide rates, domestic violence exhibited a significant association with increased suicide rates, and the national suicide prevention program was linked to reductions in suicide rates, especially among males. These findings align with research from neighbouring countries, showcasing the efficacy of suicide prevention programs in decreasing suicide rates in Chile. Results highlight the importance of integrating protocols to early-detect domestic violence in suicide prevention programs, as well as the need to further improving alcohol control policies to complement suicide prevention programs., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The meaning ascribed to suicidal behaviours may influence the quality of the care provided to people at risk of suicide. Such a phenomenon has yet to be properly investigated amongst nursing undergraduate students, the aim of this study being to gain an understanding of the meanings of suicidal behaviour for a particular group of nurses. The study, which utilized grounded theory, was conducted in Brazil in 2016-2017 with 30 undergraduate students. The findings indicated that suicidal behaviour, classified according to the individual beliefs and judgements of the participants, presented a significant barrier to the delivery of care and was complex and multifaceted care phenomenon. Participants were often reluctant to discuss the topic, seemingly wanting to distance themselves from the care of persons exhibiting suicidal behaviour, and to avoid professional engagements relating to suicide prevention. Significant work is required in raising both an awareness and knowledge of suicidal behaviour befitting the promotion of tolerance, emotional competency, resilience, and empathy amongst nursing students., (© 2017 Australian College of Mental Health Nurses Inc.)
