Adult Integrated Mental Health Services

What is Adult Integrated Mental Health Services?

AIMHS is an outpatient community mental health program that is part of Lakeridge Health. It is an integration of the former Interact and Adult Outpatient programs. We are located at the Whitby Mall. Services are offered during business hours, with the exception of limited evening groups.

What's New?

  • We have moved to a centralized intake process.
  • New group programs are expected to include psychoeducation for early bipolar disorder, stage 1 trauma treatment, mindfulness-based self-compassion, and dialectical behaviour therapy skills.

What We Offer:

We provide time-limited psychoeducation, treatment, and psychotherapy to adults over age 18. We offer a variety of treatment options, including:

  • Structured psychoeducation groups;
  • Group therapies that draw on evidence-based concepts from Cognitive Behavioural Therapy, Dialectical Behaviour Therapy, and/or transdiagnostic and skills-based approaches; and
  • Group programs that are more process-oriented, in which topics are generated by the group and the group leader(s) facilitate feedback about what is happening in the “here and now”.

What We Do Not Offer:

  • Crisis or case management services
  • Assessment for the purpose of addressing insurance, employment, or legal claims

Exclusionary Criteria:

  • Active psychosis or mania
  • Substance use or dependence that may impede the treatment process
  • Significant language, literacy, memory, or cognitive impairment(s)
  • Developmental/intellectual disability
  • Active involvement in multiple psychological treatments
  • Active involvement with ECT and/or recent course of ECT

How We Work:

  • AIMHS accepts thoroughly completed referrals via fax at (905) 434-7716. Incomplete referrals will be returned.
  • The intake clinician will review the referrals. Clients who may be suitable for service are screened by telephone. Clients are then reviewed by the AIMHS team to assess for suitability and readiness for AIMHS treatment.
  • If clients are accepted for intake, they are invited to attend at least 3 intake and orientation sessions, which may be offered in a group.
  • At the end of the intake group, clients are given feedback about their current difficulties and what might be most helpful at this time. Clients may be encouraged to pursue other community resources, particularly if they are not in a position to work on clinical goals at this time.
  • If services are offered, a collaborative plan is developed and the client will be matched with the AIMHS service that best meets their current needs.
