iTEST: Introspective Accuracy as a Novel Target for Functioning in Psychotic Disorders (iTEST)

February 24, 2026 updated by: Colin Depp, University of California, San Diego
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

Detailed Description

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

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: iTEST
Behavioral: iTEST
iTEST is a computerized training intervention delivered on a mobile device that is coupled with individual contacts with a therapist/coach. The mobile components train in improving participant's ability to form accurate judgments about their performance and their rate of functional activities. The intervention involves coaching coupled with automated training that is delivered on a mobile device. The automated training involves daily cognitive tests in which the goal for treatment is to improve judgments of accuracy of self-assessment, and coaching is aimed at applying improving metacognitive awareness to every day activities.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Trained Introspective Accuracy
Time Frame: Change from Baseline to 16 week follow up assessment
Introspective accuracy is measured daily basis from baseline to 16 weeks (average of introspective accuracy determined from self-reported estimated correct on the Variable Length List Learning Memory Test; Mobile Electronic Test of Emotion Recognition and actual correct). Each day, participants complete tasks in which the can obtain a number of correct responses in guessing the emotion depicted on a picture of a human face and remembering a list of words provided to them. Participants are then asked to guess how many items correctly identified and introspective accuracy is the absolute value of the difference between the guessed correct and actual correct. This number can range from zero to ten and lower scores reflect better introspective accuracy. There are two measures of introspective accuracy (one from a facial recognition task and the other from a word list task) and these are averaged within each day.
Change from Baseline to 16 week follow up assessment
Untrained Introspective Accuracy on WCST
Time Frame: Change from Baseline to 16 week follow up assessment
The Metacognitive Wisconsin Card Sorting Test (WCST) is a secondary measure of introspective accuracy and involves the completion of the standard neuropsychological task (WCST) with simultaneous questions about the participants judgment of correctness. The primary unit of analysis is the difference between self-assessed correct and actual correct responses. The WCST is a cognitive task that is administered by a trained rater. The scale would be the subtraction from a maximum of 64 correct and a minimum of 0 correct from the total guessed accurate (maximum of 64 or minimum of 0). Therefore the range of raw introspective accuracy scores would be from -64 to 64 and this score is then converted to an absolute value . Better introspective accuracy would be reflected by a score closer to 0.
Change from Baseline to 16 week follow up assessment
Adherence
Time Frame: Cumulative adherence over 16 weeks
Completion of daily mobile prompts divided by the number possible across 16 weeks of training.
Cumulative adherence over 16 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Specific Level of Function Scale (Informant Version)
Time Frame: Change from Baseline Assessment to 16 week follow up Assessment
The Specific Level of Functioning (SLOF) is an informant rated scale of functioning in the community. The measure includes 43 items that address current work, self-care, social and related functional capacities. The summary variable is the higher order functional factor which combines work, independent living, and social functional capacity. Each item is rated on a 1 to 5 scale where the maximum score is 5 and the minimum score is 1. The scale score is the average score rating (range of 1 to 5) with higher scores reflective of better functioning

IPD Plan Description

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

IPD Sharing Time Frame
