Abstract(s)

The recognition of warning signs by peers is a key strategy for suicide prevention. However, there are no tools to assess the knowledge of adolescents about these signs. This study aims to develop a Warning Signs Recognition for Suicidal Acts Inventory (WSSAI) and study the respective psychometric characteristics. The sample comprised 512 high-school adolescents (59% female) with a mean age 16.78 years. Exploratory and confirmatory factor analyzes, along with theoretical criteria, led to a three-factor solution (23 items) that assesses behavioral, verbal and isolation warning signs. The WSSAI presented quite satisfactory reliability and validity characteristics.
