Đào GJ, et al. - Among people with mental disorders, substance use disorders, and comorbid disorders, researchers compared use of mental health services (ie, access, number of professionals accessed, helpfulness of services received, and number of hours of services received). Study participants were respondents to the 2012 Canadian Community Health Survey-Mental Health (N = 25,133). In the level of helpfulness perceived for interventions or in time spent in professional consultation, no significant differences were found when comparing the substance use disorders and mental disorders groups vs the comorbid group. Those with concurrent disorders had a higher likelihood of accessing mental health services vs those with mental or substance use disorders alone. The overall level of access to health care was low and results of this research show numerous treatment gaps, particularly in those with substance use disorders. Steps should be taken to improve access to therapy.
