Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This project aims to evaluate the feasibility, acceptability and preliminary efficacy of remotely delivered CAE among patients with schizophrenia (CAE-S).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with schizophrenia will be randomly assigned to receive either CAE-S or eTAU following the baseline assessment. The primary feasibility outcomes will be attendance and patient satisfaction (Aim 1) and change from baseline to 12 weeks in schizophrenia symptoms as measured by the Positive and Negative Symptom Scale (PANSS) (Aim 2). An exploratory evaluation (Aim 3) will examine the posited mechanistic underpinnings of the CAE-S intervention by assessing change from screening to 12 weeks in psychotropic medication adherence as measured by the Tablets Routine Questionnaire (TRQ) and validated by eCAP (objective bottle openings). Secondary measures will include the Clinical Global Impression (CGI), functional status, quality of life and attitudes towards medication.

Customized Adherence Enhancement for Schizophrenia (CAE-S)

CAE is an adjunctive (to standard medication treatment) behavioral intervention delivered virtually (real-time one on one video-conferencing) in 6 individual sessions. All participants will receive content from the 4 currently existing CAE modules delivered over a 6-session series spaced out over approximately 6-10 weeks. The material from the 4 modules will be broken down into predetermined sub-sections and delivered in 6 sessions. The modules themselves are delivered in sections (thematic units within the module) and do not correspond to a specific session. The 4 CAE modules are Psychoeducation, Communication with Providers, Medication Routines, and Substance Use.

Group Type EXPERIMENTAL

Customized Adherence Enhancement for Schizophrenia (CAE-S)

Intervention Type BEHAVIORAL

6-session series spaced out over approximately 6-10 weeks

Enhanced Treatment as Usual (eTAU)

To optimize control intervention rigor, the eTAU participants will view a pre-taped series of 6 videos (based on NAMI or DBSA general wellness guidelines) 1:1 with a therapist who has similar credentials and competency as the CAE mental health clinician. The therapist will view the video with the participant and field questions the patient may have.

Group Type OTHER

Enhanced Treatment as Usual (eTAU)

Intervention Type OTHER

eTAU participants will view a pre-taped series of 6 videos

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Individuals age 18 and older with schizophrenia as confirmed by the Mini International Psychiatric Inventory (MINI)

* Ability to be rated on psychiatric rating scales
* Currently in treatment or scheduled to receive treatment at a Community Mental Health Clinic (CMHC) or other clinical setting able to provide mental health care during and after study participation
* Able to provide written, informed consent to study participation
* Has access to electronic device and internet to complete sessions conducted on videoconferencing platform

Exclusion Criteria

* Prior or current treatment with clozapine (clozapine therapy includes additional medication-related monitoring and clinical visits that may impact medication adherence)
* Medical condition or illness, which in the opinion of the research psychiatrist, would interfere with the patient's ability to participate in the trial
* Physical dependence on substances (alcohol or illicit drugs) likely to lead to withdrawal reaction during the course of the study in the clinical opinion of the treated research psychiatrist
