Not Applicable

Completed

Conditions: Schizophrenia
Schizoaffective Disorder

Interventions: Behavioral: PharmCAT
Behavioral: Med-eMonitor
Behavioral: Treatment as Usual

Registration Number: NCT00406718

Lead Sponsor: The University of Texas Health Science Center at San Antonio

Brief Summary: This study will determine the comparative effectiveness of two systems designed to improve medication adherence in people with schizophrenia.

Detailed Description: Schizophrenia is a severely debilitating mental disorder. People with schizophrenia often experience unusual thoughts or perceptions, decreased pleasure in everyday life, and difficulty functioning in social situations. Antipsychotic medications have been shown to be effective in improving the symptoms of schizophrenia. Poor adherence to medication, however, leads to re-hospitalization, impedes the process of recovery, and contributes to the high costs associated with schizophrenia treatment. Studies have shown that PharmCAT, cognitive adaptive training that specifically targets medication adherence, has been effective in improving adherence and outcomes in people with schizophrenia. The Med-eMonitor™ is a new pill device that is able to alert patients when they should take medication, when they are taking the wrong medication, and when they are taking medication at the wrong time. The device can also record side effect complaints and then send stored information to treatment staff. The capabilities of the Med-eMonitor™ eliminate the need for the weekly home visits that are necessary in the PharmCAT program, and may make treatment more easily available to individuals in remote or rural settings. This study will compare the effectiveness of PharmCAT, the Med-eMonitor™, and standard treatment in improving medication adherence and treatment outcome in people with schizophrenia.

Participants in this study will be randomly assigned to one of the following treatment groups: (1) PharmCAT; (2) the Med-eMonitor™; or (3) standard treatment. Participants in Group 1 will receive weekly home visits from a case manager. These visits will specifically target medication adherence. Participants in Group 2 will use the Med-eMonitor™ device. Data recorded by the device will be sent electronically to study staff. Participants in Group 3 will keep the Med-eMonitor™ device in their homes throughout the study but will not use its medication reminder function. The device will record only when medication is taken. All participants will report to the study site at study entry and Months 4, 7, and 10 for measures of symptoms, functioning, social activities, and relationships.

Arm && Interventions

Group	Intervention	Description
PharmCAT	PharmCAT	Participants will receive PharmCAT in addition to Treatment as usual, Pharm CAT is a psychosocial intervention using environmental supports such as signs, alarms, checklists, and special medication containers to cue and sequence adaptive behavior in the patient's home environment. This treatment specifically targets adherence to medication, medication education, and orientation for patients with schizophrenia. Participants will receive weekly home visits from a case manager.
Med-eMonitor	Med-eMonitor	Participants will receive Med-eMonitor™ in addition to treatment as usual. Participants will use the Med-eMonitor™ device, which is an electronic device that holds up to one month's supply of up to five medications. It is capable of cueing the taking of medication, warning patients when they are taking the wrong medication or taking it at the wrong time, recording side effect complaints, and through modem hookup promptly alerting treatment staff of failures to take medication as prescribed.
Treatment as Usual	Treatment as Usual	Participants will receive standard treatment as usual which is medication management and limited case management provided by the CMHC.

Primary Outcome Measures

Name	Time	Method
Social and Occupational Functioning Assessment Scale (SOFAS) Scores	Measured at Months 4, 7, and 10 months averaged across the treatment period which began 1 month after study baseline and ended at month 10 (total 9 mos of treatment)	Scale from 1-100 rating global social and occupational functioning. Higher scores indicate better functional outcomes
Adherence	Measured at Months 4, 7, and 10 months averaged across the treatment period which began 1 month after study baseline and ended at month 10 (total 9 mos of treatment)	Adherence derived from electronic monitoring. Percentage of medication taken during each preceding 3 month period, averaged across treatment period.

Secondary Outcome Measures

Name	Time	Method
Schizophrenia Symptoms	Measured at Months 4, 7, and 10 months averaged across the treatment period which began 1 month after study baseline and ended at month 10 (total 9 mos of treatment)	Brief Psychiatric Rating Scale (BPRS) expanded version psychosis subscale, mean of items for unusual thought content, auspiciousness, conceptual disorganization, and hallucinations. Higher scores mean greater level of symptomatology. Scores vary from 1 = absent to 7 = severe
