People with psychotic disorders experience a high level of functional disability, and a major contributor to this disability is introspective accuracy, which is defined as inaccurate judgements of one's abilities and performance on tasks. Yet, no intervention has directly targeted introspective accuracy for psychotic illnesses. This trial will evaluate a new intervention, called iTEST, that uses mobile devices to train people with psychotic disorders to improve introspective accuracy and, ultimately, functional outcomes

This NIH-supported clinical trial is the first phase of a two phase program, funded by Development of Psychosocial Therapeutic and Preventive Interventions for Mental Disorders, R61/R33. The overarching goal is to evaluate a new blended mobile intervention that is aimed at improving introspective accuracy (IA) in people with psychotic disorders, with the ultimate goal of improving functional outcome. Introspective accuracy is the degree to which one's self-assessment of performance or abilities corresponds with objective data. Recent research indicates that poor IA is an independent predictor of functional disability. Yet, there are currently no treatments that directly target IA. Basic experimental research and other lines of evidence suggest IA is malleable, and that improvement in task-based IA transfers to untrained tasks. This project's premise is that task-based IA training could be delivered in a remote mobile health format and coupled with coaching in applying improved IA to real-world functional behaviors, creating a novel avenue for functional rehabilitation in psychotic disorders. The investigators have developed and completed usability testing of iTEST, a novel blended IA targeted mobile intervention. iTEST integrates graduated drill-and-practice training in IA delivered on a mobile device with personalized coaching in applying IA to everyday compensatory behaviors. In the R61 phase trial here, the investigators will recruit people with psychotic disorders with at least minimal functional impairment. The investigators will conduct an open trial of iTEST, evaluating whether the intervention leads to clinically significant changes in task-based IA along with transfer to an untrained task (target mechanisms). The investigators will also determine the dose of intervention needed to achieve clinically significant improvement in IA targets, by evaluating change at 8, 12, or 16 weeks. The go/no go criteria for this trial are 75% adherence and clinically significant increases in introspective accuracy. A total of 60 persons who are diagnosed with schizophrenia or schizoaffective disorder will be recruited into this trial

Inclusion Criteria:

1. Voluntary informed consent to participate and capacity to consent as measured by the UCSD Brief Assessment of Capacity to Consent (UBACC)
2. Age 18 to 65;
3. DSM-5 diagnosis of schizophrenia or schizoaffective disorder based on a structured diagnostic interview and available medical record review;
4. ≥ 6th grade reading level on the Wide Range Achievement Test-4 Reading subtest (needed to read instructions on device);
5. Stable co-treatments (no hospitalizations or medication class changes in 2 months before enrollment). The investigators will determine symptom and medication stability by best-estimate history with information from medical records;
6. Availability of a clinician (staff member, case manager, other mental health clinician) or close associate (family member, friend) with at least monthly contact who can be their informant
7. Minimum level of functional impairment based on milestones, excluding participants who are full-time employed and financially responsible for their household.

Exclusion Criteria:

1. Greater than moderate disorganization on the Positive and Negative Syndrome Scale (P2-Disorganization item >5)
2. DSM-5 alcohol or substance dependence in past 3 months based on interview
3. Level of care required interferes with outpatient therapy (e.g., hospitalized; severe medical illness); 4) Unable to adequately see or manually manipulate a smartphone.

A condition of funding is that IPD is made available to other researchers through the National Data Archive of the NIMH. The investigative team will deposit and share data in the NIMH National Data Archive and the investigative team has budgeted staff time of 100 hours per year to accomplish the preparation, curation, and uploading of semiannual de-identified data as the study progresses (linked with Global Unique Identifiers) to the online system in collaboration with NIH staff. • The investigative team will develop documents and tools to support this dissemination, in particular for the sharing ecological momentary assessment data which presents data management challenges in its volume and complexity, including within-person aggregation scripts that can be used to analyze the data at the day and week level. IPD that will be shared include all de-identified study data

Data will be made available by September 2025, which is within 6 months of the conclusion of the award. This is consistent with NIMH policy on the timing of data sharing and data will be shared in perpetuity.
