BESS University/College Student Form
University/College leaders are increasingly concerned about the mental health needs of their students. Students are also aware of their growing mental health needs and look to their universities/colleges to provide support. The BESS University/College Student Form provides a quick, reliable and confidential way for counselling centres and student health services to screen large numbers of students.
Campus-wide mental health checks using the BESS provide valuable information for addressing individual student needs and for planning prevention and wellbeing promotion activities across the entire campus.
