What is one key risk factor for suicide identified in the SAD PERSONS scale?

The key risk factor for suicide identified in the SAD PERSONS scale is the age range of 15-34 and 65+. This scale is specifically designed to assess suicide risk based on various factors, and this particular age range highlights two critical periods in a person's life when they may be more vulnerable to suicidal thoughts and behaviors.

Young adults, typically aged 15-34, often face transitional life challenges such as educational pressures, relationship issues, and identity formation. Similarly, older adults aged 65 and above may encounter significant life changes, including retirement, loss of loved ones, and physical health deterioration, making them susceptible to feelings of hopelessness or despair. This understanding helps healthcare professionals identify individuals who may need additional support or intervention based on their age-related risk factors.

While marital status, employment status, and presence of children can also influence suicide risk, the specific age ranges provided in the correct answer serve as critical indicators used in the SAD PERSONS scale for assessing potential suicide risk.
