Brief Summary:
The investigators propose a cluster randomized effectiveness trial comparing Cognitive Adaptation Training (CAT; a psychosocial treatment using environmental supports such as signs, alarms, pill containers, checklists, technology and the organization of belongings established in a person's home or work environment to bypass the cognitive and motivational difficulties associated with schizophrenia ) to existing community treatment (CT) for individuals with schizophrenia in 8 community mental health centers across multiple states including 400 participants. Mechanisms of action will be examined. Participants will be assessed at baseline and 6 and 12 months on measures of functional and community outcome, medication adherence, symptoms, habit formation and automaticity, cognition and motivation.

Schizophrenia Schizoaffective Disorder Behavioral: Cognitive Adaptation Training Behavioral: Community Treatment Not Applicable

Detailed Description:
Schizophrenia remains one of the most disabling conditions world-wide with an economic burden that exceeded $155 billion dollars in fiscal year 2013 alone. Despite existing medication and community treatment, many individuals with this diagnosis continue to have poor outcomes and struggle toward recovery. CAT is a psychosocial treatment using environmental supports such as signs, alarms, pill containers, checklists, technology and the organization of belongings established in a person's home or work environment to bypass the cognitive and motivational difficulties associated with schizophrenia, and support habits for functional behavior to promote recovery. In a series of efficacy studies, CAT improved social and occupational functioning, symptoms, and adherence to medication, and reduced rates of readmission. The investigators propose a cluster randomized effectiveness trial comparing Cognitive Adaptation Training (CAT) to existing community treatment (CT) for individuals with schizophrenia in 8 community mental health centers across multiple states including 400 participants. This would be the first large-scale effectiveness study of CAT for improving functional outcomes for those with schizophrenia seen in community mental health centers (CMHCs) where the majority of those with schizophrenia are followed for outpatient care and to study the purported mechanisms of action based on an integrated theoretical model. Participants will be assessed at baseline and 6 and 12 months on measures of functional and community outcome, medication adherence, symptoms, habit formation and automaticity, cognition and motivation. CAT treatment will be weekly for 6 months, biweekly for 3 months and monthly for the remainder of the trial. Purported mechanisms of action for CAT including bypassing impairments in cognitive function to improve functional outcome and bypassing motivational impairments to create automatic habits to improve functional outcome will be examined.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in Social and Occupational Functioning Scale Scores [ Time Frame: baseline, 6 months, 12 months ]
    A rating from 0-100 reflecting global level of Social and Occupational functioning; Higher scores indicate better functioning.


Secondary Outcome Measures :
  1. Change in Daily activity [ Time Frame: baseline, 6 months, 12 months ]
    Negative Symptom Assessment item 14 assessing typical daily behavior using a structured interview with behavioral anchor points. Scale is rated 1 to 6 with higher scores indicating lower levels of engagement in daily activity (i.e. more severe apathy)

  2. Change in Multnomah Community Ability Scale mean score [ Time Frame: baseline, 6 months, 12 months ]
    Assessment of community functioning on a 17 -item scale with domains assessing interference with functioning, adjustment to living, social competence and behavioral problems. Items are averaged to produce a mean score. Items are each rated on a scale from 1-5 with higher scores reflecting better community functioning.

  3. Change in Adherence Estimate Score [ Time Frame: baseline, 6 months, 12 months ]
    A 3 item scale assessing variables associated with adherence. Items are rated based upon self report about the importance of taking medication, worry about medication and financial burden of medication on a scale from agree completely to disagree completely. Each answer is assigned points based on an algorithm and added producing a total score. Higher scores indicate a higher risk for adherence and a lower probability of adherence. Scores range for 0 to 100.

  4. Change in Negative Symptom Assessment-16 Mean Score [ Time Frame: baseline, 6 months, 12 months ]
    Assesses 16 negative symptoms in the domains of communication, emotion/affect, social activity, motivation and psychomotor activity on a scale from 1-6. Items are added and divided by 16 to produce a mean score. A global score is also produced based upon clinical judgement following the interview Higher scores reflect higher levels of negative symptoms.

  5. Change in the Expanded Version Brief Psychiatric Rating Scale (BPRS)-total score [ Time Frame: baseline, 6 months, 12 months ]
    24 item scale assessing multiple dimensions of psychopathology including positive symptoms; negative symptoms, anxiety/depression, and activation on a series of 7 point scales. Higher scores reflect higher levels of symptoms.


Other Outcome Measures:
  1. Change in Effort Expenditure for Rewards Task (EEfRT) Probability Difference score [ Time Frame: baseline, 6 months, 12 months ]
    computerized task of effort put forth to win various amounts of money under various levels of probability. The probability difference score equals the percent of hard choices in the high probability condition minus the percent of hard choices in the low probability condition. Higher scores indicate more frequent choices of hard tasks at the high versus low probability level. individuals who answer the same way on all tasks are eliminated (estimate 1%)

  2. Change in global score of Brief Assessment of Cognition (BACS) App [ Time Frame: baseline, 6 months, 12 months ]
    Ipad delivered version of BACS assessing memory, attention, executive function and psychomotor speed. Standard scores are generated and summed to create a global cognition score with higher scores indicating better levels of cognitive function.
