Objectives Raue and Sirey proposed a theoretical treatment engagement model for older adults outlining steps from identifying mental health problems, referral to specialty care, and involvement in treatment. Using this model as a guide, the current study aimed to explore patient perspectives of their experience in the process of referral and first meeting with geriatric mental health services. Furthermore, the current study aimed to identify opportunities to enhance patient engagement in these beginning steps of the treatment engagement process. Method Thirteen geriatric outpatients (7 psychology, 6 psychiatry) presenting with concerns of anxiety, depression, and/or stress were interviewed. Interviews were analyzed using the framework method. Results Themes emerged as suggested by Raue and Sirey’s model, including attitudes toward treatment (e.g. stigma), treatment expectations, and treatment preferences. In addition, new themes emerged related to modifiable individual factors (the patient as a passive recipient of care, mental health literacy, and ageism) as well as social influences on treatment engagement. Participants primarily noted opportunities for psychoeducation as a potential treatment engagement intervention to implement within the current referral system. Conclusions This is the first study to examine the applicability of Raue and Sirey’s theoretical engagement model in a clinical sample. Findings both support and expand the model and offer several recommendations for improving treatment engagement for older patients.
