The 2018 Annual Report summarizes data contributed to the Center for Collegiate Mental Health (CCMH) during the 2017-2018 academic year, beginning July 1, 2017 and ending on June 30, 2018. De-identified data were contributed by 152 college and university counseling centers, describing 179,964 unique college students seeking mental health treatment, 3,723 clinicians, and over 1,384,712 appointments. Among other highlights, this year's report examined the impact of two counseling center policies on treatment outcomes: (1) EMR Sharing Policy: Levels of access to counseling center EMRs by health center staff (none, partial, or open) were not associated with significant differences in symptom reduction during treatment in counseling center clients.; and (2) Clinical Model Policy: Counseling centers that use a treatment model (e.g., students are assigned to a clinician when an opening exists) produced significantly more symptom reduction, provided a significantly greater dosage of treatment (appointments per student), and offered significantly shorter wait-times between appointments than counseling centers that utilized an absorption model. [Additional support for this research comes from the collaborative efforts of approximately 500 university and college counseling centers and the Penn State University Counseling & Psychological Services.
