Abstract Background A patient’s readiness for discharge can be assessed from the perspectives of the clinician, patient, and family. Criterion-based assessment by the clinician is the most commonly reported method, but there is no ecologically valid method available to assess readiness for discharge while in the hospital. The Virtual Reality Functional Capacity Assessment Tool (VRFCAT) is a novel game-based program, that provides a sequence of objectives related to activities involved in a multi-level shopping task. The aim of the present study was (1) to examine the feasibility of administering the VRFCAT in a population of very low functioning patients with chronic schizophrenia, (2) to relate the performance of the study patients to standardized VRFCAT performance data of higher functioning patients (Keefe et al. 2016), (3) to assess the concurrent validity of the VRFCAT in this population, and (4) to correlate the performance measures to measures of community adjustment 4 weeks after hospital discharge. Methods The VRFCAT was administered after informed consent to inpatients with DSM 5 diagnosis of chronic schizophrenia, who were eligible for discharge from a long-term inpatient psychiatric facility. Independent variables included the VRFCAT time to completion (adjusted total time), number of errors on 12 VRFCAT objectives, and the number of times that an individual failed to complete a task (forced progression). The SLOF, the UPSA-B and the PSP were completed for concurrent validity. Patients were followed for one month after their discharge to assess the level of their community adjustment as measured by the SLOF, the UPSA-B and the PSP. Results Of the 80 subjects enrolled, a total of 72 subjects had evaluable data with a mean age of 41.23 years (SD = 10.11). 55.56% of subjects also had an axis I substance use diagnosis. The mean level of education was 9.89 (SD = 2.69) and 56.94% of patients had a history of incarceration. When compared to higher functioning patients’, participants performed 2.5 standard deviations below the mean for the adjusted total time (Mean T Score = 24.89, SD = 16.56), total errors (T = 24.11, SD = 22.69), and 2 SDs below the mean for total forced progressions (T = 29.56, SD = 14.311). VRFCAT test-retest reliability showed unchanged mean T scores: total time (T Score = 23.11, SD = 16.23), total errors (T = 23.56, SD = 22.00). Pearson correlations at baseline for 4 of 12 VRFCAT objectives with concurrent SLOF Activities (Pay fo
