Not Applicable

Completed

• Conditions: Schizophrenia; Overweight; Mental Disorders; Obesity
• Interventions: Behavioral: Psychosocial Weight Intervention

• Registration Number: NCT02183844
• Lead Sponsor: University of California, Los Angeles

Brief Summary

It is important that individuals with serious mental illness make informed choices among alternative healthcare treatments based on their preferences. However, at present, individuals' preferences are often not being elicited, nor used to guide which treatments are made available. In this pilot project, the investigators implement and evaluate a computerized method for assessing treatment preferences of individuals with schizophrenia. The investigators use weight management treatments for this initial test of the system. If this assessment method is found to predict treatment use and satisfaction, it can be used to guide implementation of treatments that improve outcomes while meeting individuals' preferences.

Detailed Description

Background/Rationale: It is important that individuals with serious mental illness have access to treatments that meet their preferences, and that they make informed choices among alternative treatments. Too often, preferences are not being routinely elicited, nor used to guide which treatments are made available. Schizophrenia is a serious mental illness that is common and produces substantial disability when poorly treated. National treatment guidelines specify that individuals with schizophrenia should receive evidence-based treatments that improve outcomes. For example, obesity is a pressing problem in this population, a side-effect of commonly used medications, and a cause of cardiovascular disease and premature mortality. There are multiple, different psychosocial interventions for weight management that can lead to reduced weight. None are widely used. If individuals' preferences were routinely assessed, then clinicians and managers would know when to make alternative treatments available.

Objectives: This project implements and evaluates a method for routinely assessing the treatment preferences of individuals with schizophrenia. The objectives are to: 1) develop a computerized, kiosk-based system that delivers education regarding treatment options for weight, uses conjoint analysis to elicit preferences, and meets the cognitive needs of individuals with schizophrenia; 2) study the feasibility and acceptability of implementing this method at a mental health clinic; and, 3) evaluate the extent to which this method predicts use of evidence-based weight services, and satisfaction with services at three months.

Methods: This is a prospective evaluation of preferences, treatment use, and satisfaction in individuals with schizophrenia. 94 individuals are enrolled who are overweight and receiving treatment at a busy, urban mental health clinic. These participants use a kiosk system that provides them with education about treatment options, and assesses their preferences regarding alternative treatments for weight. They are then offered a weekly, intensive, evidence-based psychosocial treatment for weight. Research assessments occur at baseline and 3 months. Treatment preferences are analyzed to determine how they relate to use of weight treatment, and satisfaction with treatment.

Significance: People with serious mental illness could benefit from access to effective treatments. Implementing these treatments would be facilitated by routinely collecting information regarding individuals' preferences. If the assessment method in this study is found to be feasible, acceptable, and accurate, it could be used to support implementation of improved care at clinics, medical centers, and community-based programs.

Arm && Interventions

Group	Intervention	Description
Psychosocial Weight Intervention	Psychosocial Weight Intervention	Weekly group intervention for diet and exercise, designed specifically for individuals with serious mental illness and the cognitive deficits that accompany those illnesses

Primary Outcome Measures

Name	Time	Method
Days until using weight services	3 months	Utilization of the weight services offered. This includes the number of days until starting to use weight services. This is assessed using information regarding attendance at weight services, and by survey administered by interview.
Participant preferences regarding weight services	Baseline	Individuals' preferences are assessed regarding different attributes of weight treatments. These are assessed using computerized conjoint analysis methods.
Satisfaction with the weight services provided	3 months	Satisfaction with the weight services provided. This is assessed using the Client Satisfaction Questionnaire administered by interview.
Number of weight services used	3 months	Utilization of the weight services offered. This includes the number of weight service sessions attended. This is assessed using information regarding attendance at weight services, and by survey administered by interview.

Secondary Outcome Measures

Name	Time	Method
Feasibility and acceptability of implementing preference assessment	Baseline	Feasibility and acceptability of implementing kiosk-based preference assessment at a mental health clinic. This is assessed using project records, surveys, and semi-structured interview questions assessing whether participants and staff find the program and its components to be advantageous, relevant, simple, easy to use, and beneficial.
