Brief summary
This study will determine the effectiveness of various combinations of psychosocial therapy and risperidone treatment in improving work or school performance in people with first-episode schizophrenia.
Detailed description
Schizophrenia is a chronic, severe, and disabling brain disorder. People with schizophrenia often experience hallucinations, delusions, thought disorders, and movement disorders. These symptoms make it difficult to maintain a job, participate in school, and keep up self-care. Proper treatment of first-episode schizophrenia may increase the chances of controlling disease progression on a long-term basis. Antipsychotic medications, such as risperidone, and psychosocial treatments, such as cognitive enhancement training and health behavior training, are common, effective treatments for schizophrenia. This study will determine the effectiveness of various combinations of psychosocial therapy and risperidone treatment in improving work or school performance in people with first-episode schizophrenia. Participants in this open label study will be randomly assigned to receive one of the following four combinations of an antipsychotic medication and a psychosocial treatment: cognitive enhancement training plus oral risperidone; cognitive enhancement training plus long-acting injectable risperidone; health behavior training plus oral risperidone; or health behavior training plus long-acting injectable risperidone. Cognitive enhancement training will entail 2 hours per week of computer-assisted training targeted at improving attention, memory, and problem-solving skills. Additionally, participants will attend a weekly 1-hour group meeting to learn how to apply these skills to work and school situations. Health behavior training will involve 3 hours per week of relaxation training, nutrition education, and physical exercise to enhance wellness. Participants assigned to receive oral risperidone will receive their medication in pill form at the dosage determined to be optimal by the study psychiatrist. Participants assigned to receive injectable risperidone will be given one injection every 2 weeks. Dosages will start at 25 mg per injection and will be adjusted as needed. Treatment will continue for 1 year following dosage stabilization, which typically occurs 2 to 3 months following study entry. For the first 6 months, participants assigned to receive health behavior training will attend study visits once a week and participants assigned to receive cognitive enhancement training will attend study visits once a week. For the final 6 months, all participants will attend study visits twice weekly. At each visit, participants will receive their assigned psychosocial treatment; attend group therapy; meet with a case manager for counseling and assessment of symptoms, work functioning, and social functioning; and meet with a psychiatrist to monitor medication response. Additional cognitive and health behavior measures will be taken every 6 months to assess treatment effectiveness.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) | Measured at baseline and 12 months | Values presented here are the changes in MCCB Overall Composite T scores from baseline to 12 months, with higher values representing better outcome. Raw test scores are used to generate T-scores and then the seven MCCB domains are combined to generate an Overall Composite T score. MCCB Overall Composite T scores have a mean in the general population of 50 with a standard deviation of 10. Thus, a positive change of 5 T scores is an improvement of half a standard deviation. |
| Work/School Functioning (Global Functioning Scale: Role) | Baseline to 6 months | Change in role functioning from baseline to the 6 month point (rated on a scale from 1= Extreme Role Dysfunction to 10 = Superior Role Functioning) is presented here. |
| Average Medication Non-adherence | Averaged over study participation (up to 12 months) | 5-point scale (1 = best adherence, 5= nonadherent) based on pill counts, Medication Event Monitoring System (MEMS) cap readings, plasma assays, and psychiatrist judgements for oral risperidone and timing of injections for long-acting injectable risperidone. Averaged over medication study participation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Retention in Treatment | 12 months | Days after randomization that a participant continued to receive at least the assigned CT or HBT psychosocial treatment. If a participant needed to end the assigned medication condition (RLAI vs. Oral Ris), they continued in the psychosocial treatment so this outcome focused on the days in the assigned psychosocial treatment. Possible range is 1 to 365, with higher being a better outcome. |
| Awareness of Illness, as Assessed by the Scale to Assess Unawareness of Mental Disorder, Revised Version (SUMD-R) | 12 months after randomization | Rating scale based on clinician's interview of patient to determine level of lack of awareness of having a mental disorder. Range is from 1 (Aware) to 5 (Unaware), so lower scores indicate better outcome. |
| Work Behavior Inventory (WBI) Quality of Work/School Performance | Baseline to 1 year | Change in rating on quality of work/school performance based on patient, employer, and/or teacher reports. The Quality of Work rating at baseline was subtracted from the same rating at 12 mos. Higher scores are better outcome. |
| Change in Coping Strategies | Baseline to 12 months | Coping Response Inventory, which rates extent to which active coping strategies were used after a significant stressful life event. Range of possible scores is 1 to 4. Higher scores are better. |
| Change in Motivation for Work/School | Baseline to 12 months | The Work Motivation scale is a factor score from the Work Personality Profile. The Work Personality Profile is a set of ratings based on interviewing the participant. Scores at each occasion can range from 8 to 32, with higher indicating better motivation. Scores reported here are changes from baseline to 12 months, which could range from -24 to 24 with higher being better. |
| Maintenance of Work/School Attendance | 12 months | Modified Work Section of the Social Adjustment Scale (SAS) was used to calculate the total number of weeks in school or competitive work. Range of possible values is 0 to 52, with higher numbers being better outcome. |
| Exacerbation or Relapse of Psychotic Symptoms | Occurence after randomization and until end of study participation (up to 12 mos.) | Dichotomous measure: Presence of any of 3 psychotic relapse or exacerbation categories scored from the Brief Psychiatric Rating Scale (BPRS) occurring after randomization and until end of study participation (up to 12 months post baseline). BPRS was administered every two weeks throughout study participation. |

Outcome results
Average Medication Non-adherence
5-point scale (1 = best adherence, 5= nonadherent) based on pill counts, Medication Event Monitoring System (MEMS) cap readings, plasma assays, and psychiatrist judgements for oral risperidone and timing of injections for long-acting injectable risperidone. Averaged over medication study participation.
Time frame: Averaged over study participation (up to 12 months)
Population: A priori hypothesis was that long-acting injectable risperidone would result in better medication adherence than oral risperidone, so CT and HBT groups were merged within each medication administration condition.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| CT - RLAI | Average Medication Non-adherence | 1.0 units on a 5-point scale | Standard Deviation 0.1 |

Change in Coping Strategies
Coping Response Inventory, which rates extent to which active coping strategies were used after a significant stressful life event. Range of possible scores is 1 to 4. Higher scores are better.
Time frame: Baseline to 12 months
Population: Participants with Coping Response Inventories completed for a comparable stressful life event at baseline and 12 months. This was so rare in practice that this outcome was not feasible to evaluate.
Change in Motivation for Work/School
The Work Motivation scale is a factor score from the Work Personality Profile. The Work Personality Profile is a set of ratings based on interviewing the participant. Scores at each occasion can range from 8 to 32, with higher indicating better motivation. Scores reported here are changes from baseline to 12 months, which could range from -24 to 24 with higher being better.
Time frame: Baseline to 12 months
Population: Participants in school or jobs at baseline and 12 months, which allows change in Work Personality Profile ratings to be assessed.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| CT - RLAI | Change in Motivation for Work/School | 3.7 score on a scale | Standard Deviation 2.3 |
| HBT - RLAI | Change in Motivation for Work/School | 1.2 score on a scale | Standard Deviation 4.6 |
| CT - Oral Ris | Change in Motivation for Work/School | -2.4 score on a scale | Standard Deviation 7.4 |
| HBT - Oral Ris | Change in Motivation for Work/School | -1.9 score on a scale | Standard Deviation 6.5 |
Exacerbation or Relapse of Psychotic Symptoms
Dichotomous measure: Presence of any of 3 psychotic relapse or exacerbation categories scored from the Brief Psychiatric Rating Scale (BPRS) occurring after randomization and until end of study participation (up to 12 months post baseline). BPRS was administered every two weeks throughout study participation.
Time frame: Occurence after randomization and until end of study participation (up to 12 mos.)
Population: A priori hypothesis was that RLAI would lead to fewer psychotic exacerbations/relapses than Oral Ris. No effect of CT vs. HBT was hypothesized, so CT and HBT conditions were merged within each medication administration condition.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| CT - RLAI | Exacerbation or Relapse of Psychotic Symptoms | 2 participants |
| HBT - RLAI | Exacerbation or Relapse of Psychotic Symptoms | 10 participants |
Maintenance of Work/School Attendance
Modified Work Section of the Social Adjustment Scale (SAS) was used to calculate the total number of weeks in school or competitive work. Range of possible values is 0 to 52, with higher numbers being better outcome.
Time frame: 12 months
Population: Participants who were served by the Individual Placement and Support specialist
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| CT - RLAI | Maintenance of Work/School Attendance | 35.4 weeks | Standard Deviation 21.2 |
| HBT - RLAI | Maintenance of Work/School Attendance | 24.4 weeks | Standard Deviation 19.8 |
| CT - Oral Ris | Maintenance of Work/School Attendance | 26.7 weeks | Standard Deviation 20 |
| HBT - Oral Ris | Maintenance of Work/School Attendance | 12.0 weeks | Standard Deviation 12.8 |
Retention in Treatment
Days after randomization that a participant continued to receive at least the assigned CT or HBT psychosocial treatment. If a participant needed to end the assigned medication condition (RLAI vs. Oral Ris), they continued in the psychosocial treatment so this outcome focused on the days in the assigned psychosocial treatment. Possible range is 1 to 365, with higher being a better outcome.
Time frame: 12 months
Population: All participants who received Individual Placement and Support
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| CT - RLAI | Retention in Treatment | 359.7 days | Standard Deviation 8.1 |
| HBT - RLAI | Retention in Treatment | 352.2 days | Standard Deviation 26.9 |
| CT - Oral Ris | Retention in Treatment | 332.4 days | Standard Deviation 38.8 |
| HBT - Oral Ris | Retention in Treatment | 348.3 days | Standard Deviation 28.4 |
Work Behavior Inventory (WBI) Quality of Work/School Performance
Change in rating on quality of work/school performance based on patient, employer, and/or teacher reports. The Quality of Work rating at baseline was subtracted from the same rating at 12 mos. Higher scores are better outcome.
Time frame: Baseline to 1 year
Population: This measure could be rated only for individuals who were in school or working at baseline and at 12 months, so it proved not to be useful due to the infrequent return to school or work by baseline.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| CT - RLAI | Work Behavior Inventory (WBI) Quality of Work/School Performance | -6.5 score on a rating scale | Standard Deviation 31.8 |
| HBT - RLAI | Work Behavior Inventory (WBI) Quality of Work/School Performance | 8.8 score on a rating scale | Standard Deviation 34 |
| CT - Oral Ris | Work Behavior Inventory (WBI) Quality of Work/School Performance | -3.4 score on a rating scale | Standard Deviation 17.4 |
| HBT - Oral Ris | Work Behavior Inventory (WBI) Quality of Work/School Performance | 0.0 score on a rating scale | Standard Deviation 33.9 |
