Which is a protective factor in suicide risk assessment?

• A. Access to a firearm
• B. Substance use
• C. Severe mental illness
• D. Strong social support network

Answer: (D)

Strong social support networks act as a protective factor because they provide connection, emotional support, and practical help that buffer against crisis. When someone has trusted people to lean on—family, friends, coworkers, faith or community groups—they’re more likely to talk about suicidal thoughts, seek help, and adhere to treatment. This sense of belonging reduces isolation, fosters coping skills, and creates opportunities for early intervention, all of which lower the chance of a suicide attempt or its lethality.

In contrast, access to lethal means, such as a firearm, increases risk because it makes impulsive crises more deadly and reduces the time for intervention. Substance use heightens risk by impairing judgment, increasing impulsivity, and worsening mood or despair. Severe mental illness is itself a significant risk factor due to symptoms like hopelessness, impaired functioning, and treatment barriers, though protective factors like a solid support system can mitigate some of that risk.

So the strongest protective factor among these choices is a robust social support network, because it directly enhances connection, encourages help-seeking, and provides ongoing resources during difficult times.
