Outcome Measures

Primary Outcomes (3)

  • Social Functioning utilizing the Social Functioning Scale.

    Between-group magnitude of change in social functioning utilizing the Social Functioning Scale. The Social Functioning Scale (SFS) was constructed specifically to tap areas of social functioning that are crucial to the community maintenance of individuals with schizophrenia. The 7 domains include: social engagement/withdrawal, interpersonal behavior, pro-social activities, recreation, independence-competence, independence-performance, and employment/occupation. The raw scores for each domain are converted to scaled scores, with a mean of 100 and a standard deviation of 15. Higher scores are indicative of greater social functioning.

    At 9 weeks

  • Negative Symptoms utilizing the Positive and Negative Syndrome Scale.

    Between-group magnitude of change in negative symptoms utilizing the Positive and Negative Syndrome Scale. The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia. A rating from 1 to 7 is given to each of the 30 different symptoms. The 7-point rating represents increasing levels of psychopathology: 1= absent, 2=minimal, 3=mild, 4=moderate, 5=moderate severe, 6=severe, and 7=extreme. Of the 30 items included in the PANSS, 7 constitute a Positive Scale, 7 a Negative Scale, and the remaining 16 a General Psychopathology Scale. The scores for these scales are arrived at by summation of ratings across component items. Therefore, the potential ranges are 7 to 49 for the Positive and Negative Scales, and 16 to 112 for the General Psychopathology Scale. Higher scores are indicative of greater symptomatology.

    At 9 weeks

  • Quality of Life utilizing the Abbreviated Quality of Life Scale.

    Between-group magnitude of change in quality of life utilizing the Abbreviated Quality of Life Scale. The Quality of Life Scale (QLS) is a scale commonly used as a measure of functioning in schizophrenia. The Abbreviated QLS (aQLS) includes 7 items representing all four interdependent theoretical constructs of the original 21-item QLS. Behavioral anchors are presented for each item, scored on a 0 (severe impairment) to 6 (high functioning) scale. Higher scores are indicative of greater quality of life.

Experimental Treatment

EXPERIMENTAL

Computerized cognitive training for 18 hours and structured social skills training for 9 hours over a 9 week period.

Other: Computerized Plasticity-Based Adaptive Cognitive TrainingOther: Optimized social skills training

Active Comparator

ACTIVE COMPARATOR

Commercially-available computerized training for 18 hours and 9 hours of unstructured support group sessions over a 9 week period.

Other: Commercially available computerized trainingOther: Unstructured support group sessions

Interventions

Training on computerized exercises that targets social cognition for 2 hours per week.

Experimental Treatment

Training on computerized, casual video games for 2 hours per week.

Active Comparator

Group-video calls with Specialist for 1 hour per week where participants can interact with Specialist individually or as a group. Specialist will provide guidance, support and feedback, and send links and articles about information and topics discussed during the video calls.

Experimental Treatment

Unstructured support group-video calls for 1 hour per week. The Specialist will not engage with participants (eg. providing participants with links to articles and additional support) or provide guidance for the group discussion.
