While evidence has yet to identify ideal candidates for e-mental health, it is likely that these interventions are an appropriate option for people who have an increased risk of developing mental illness, or who are already experiencing mild to moderate symptoms of mental illness.
There is less evidence for the use of e-mental health interventions with people who have complex or severe mental illness, comorbid personality disorders, substance dependence, or people who have an elevated risk of self-harm or suicide and require urgent clinical management.
