    <textblock>
      The primary objective of this study is to evaluate the efficacy of SocialVille, an online&#xD;
      training program we have recently developed (with support of a Phase I SBIR award) to treat&#xD;
      the social cognition deficits evident in schizophrenia (DSM-IV ICD-9 Code 295.90).&#xD;
&#xD;
      SocialVille is a computerized, browser-playable program suite, designed to target information&#xD;
      processing in the core social cognition domains of deficit in schizophrenia. It can be used&#xD;
      from any internet-connected computer; through a dedicated clinician portal, the treating&#xD;
      clinician can register users to treatment, continuously track and monitor their performance,&#xD;
      and coach users throughout training. The specific aims of the study are:&#xD;
&#xD;
        1. Specific Aim 1: Evaluate the efficacy of SocialVille as a social cognition treatment in&#xD;
           individuals with schizophrenia. We will conduct a large-scale, multi-site, double-blind,&#xD;
           randomized controlled clinical trial of the SocialVille medical device vs. an active&#xD;
           computer games control, which approximates challenge, computer time and interaction with&#xD;
           experimenter. This large trial will be conducted at four sites: University of Minnesota&#xD;
           Medical School (site PI: Dr. Sophia Vinogradov), the Greater Los Angeles VA (Dr. Michael&#xD;
           Green), Rush University (Dr. Christine Hooker), and University of California, Los&#xD;
           Angeles (Drs. Joseph Ventura and Keith Nuechterlein). Study participants will complete&#xD;
           30 hours of training from home. At baseline, mid-way through training and immediately&#xD;
           following training, we will employ a structured assessment battery with a co-primary SC&#xD;
           performance measure and a co-primary functional performance measure, as well as&#xD;
           secondary measures of SC, functional capacity, functional outcome, motivation, and&#xD;
           quality of life.&#xD;
&#xD;
        2. Specific Aim 2: Identify specific populations of treatment responders and&#xD;
           non-responders. We will examine predictors of SC gain based on baseline participant&#xD;
           demographic, symptom level, computer use, SC, and functional measures, as well as on&#xD;
           learning rate and plateau performance measures derived over the course of SocialVille&#xD;
           use to determine if it is possible to identify specific populations that respond very&#xD;
           well to SocialVille use, or those who are unlikely to respond to SocialVille use.&#xD;
&#xD;
        3. Specific Aim 3: Evaluate the effects of training on the relatively distinct low vs.&#xD;
           high-level social cognition constructs. We will separately examine the effects of&#xD;
           training on the independent SC factors of low level social cue detection and high-level&#xD;
           inferential process, correlated with clinical symptoms and functional outcome,&#xD;
           respectively.&#xD;

    <measure>Change in Performance on the UCSD Performance-based Skills Assessment (Co-Primary Composite Measure)</measure>
    <time_frame>At 6 weeks and At 12 weeks</time_frame>
    <description>The a priori co-primary functional measure will be the functional capacity measure of The UCSD Performance-based Skills Assessment (UPSA) - total correct. Higher scores indicate better performance. We have chosen the UPSA since it is a well-validated measure frequently used in cognitive and SC training studies; In addition, it measures functional capacity, which is expected to be affected by SC change. The UPSA is designed to assess skills in five areas (Household Chores, Communication, Finance, Transportation, and Planning Recreational Activities) that reflect general abilities that are important components of independent living. Test-retest reliability ranged from .63-.80 over follow-up periods up to 36 months in patients with schizophrenia. Among patients, the UPSA performance correlated significantly with severity of negative symptoms and of cognitive impairment but not with that of positive or depressive symptoms.</description>

This study is a multi-site, prospective, parallel arm, double-blind, randomized, controlled
      clinical trial to assess the efficacy of an experimental software program targeting social
      cognitive abilities versus a computer-based software control. Both the study and the software
      being investigated meet the criteria of Non-Significant Risk.
The primary objective of this study is to evaluate the efficacy of SocialVille, an online
      training program we have recently developed (with support of a Phase I SBIR award) to treat
      the social cognition deficits evident in schizophrenia (DSM-IV ICD-9 Code 295.90).

      SocialVille is a computerized, browser-playable program suite, designed to target information
      processing in the core social cognition domains of deficit in schizophrenia. It can be used
      from any internet-connected computer; through a dedicated clinician portal, the treating
      clinician can register users to treatment, continuously track and monitor their performance,
      and coach users throughout training. The specific aims of the study are:

        1. Specific Aim 1: Evaluate the efficacy of SocialVille as a social cognition treatment in
           individuals with schizophrenia. We will conduct a large-scale, multi-site, double-blind,
           randomized controlled clinical trial of the SocialVille medical device vs. an active
           computer games control, which approximates challenge, computer time and interaction with
           experimenter. This large trial will be conducted at four sites: University of Minnesota
           Medical School (site PI: Dr. Sophia Vinogradov), the Greater Los Angeles VA (Dr. Michael
           Green), Rush University (Dr. Christine Hooker), and University of California, Los
           Angeles (Drs. Joseph Ventura and Keith Nuechterlein). Study participants will complete
           30 hours of training from home. At baseline, mid-way through training and immediately
           following training, we will employ a structured assessment battery with a co-primary SC
           performance measure and a co-primary functional performance measure, as well as
           secondary measures of SC, functional capacity, functional outcome, motivation, and
           quality of life.

        2. Specific Aim 2: Identify specific populations of treatment responders and
           non-responders. We will examine predictors of SC gain based on baseline participant
           demographic, symptom level, computer use, SC, and functional measures, as well as on
           learning rate and plateau performance measures derived over the course of SocialVille

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.
measure: Motivational systems utilizing Behavioral Inhibition/Behavioral Activation Scale
time frame: At 6 weeks and At 12 weeks
description: Between-group magnitude of change in motivational systems utilizing the Behavioral Inhibition/Behavioral Activation Scale (BIS-BAS) - BAS drive, fun seeking, reward, and BIS scores. The Behavioral Inhibition/Behavioral Activation Scale is a 24-item self-report questionnaire designed to assess the two general motivational systems that underlie behavior and affect, i.e. sensitivity to anticipated punishment or reward. Higher scores indicate greater sensitivity to punishment or reward.
