Brief summary

Self-directed care (SDC) programs give people with disabilities control over public funds to purchase traditional behavioral health and non-traditional services in order to remain outside of institutional settings. The purpose of this study is to determine the effects of this model on participant outcomes, service costs, and user satisfaction among people with serious mental illness.

Detailed description

Self-directed care (SDC) programs give people with disabilities control over public funds to purchase traditional behavioral health and non-traditional services in order to remain outside of institutional settings. The purpose of this study is to determine the effects of this model on participant outcomes, service costs, and user satisfaction among people with serious mental illness. Adults with serious mental illness served in the Texas public health system will be randomly assigned to SDC versus services as usual and assessed at baseline, 12-month, and 24-month follow-up. Mixed effects random-regression analysis will test for longitudinal changes in outcomes between the two study conditions. Differences in service costs will be analyzed using generalized linear models with negative binomial and zero-inflated negative binomial distribution. Non-traditional expenditures by the SDC participants will be examined descriptively. Service satisfaction in both study conditions will be assessed at one- and two-year follow-up.

Interventions

Traditional and non-traditional behavioral health services are chosen from within and outside the public mental health system

BEHAVIORALServices as usual

Traditional behavioral health services are chosen from along those delivered at the patient's community mental health agency

Intervention model description

Self-directed care is a model of service delivery in which service recipients are allocated a individual budget from which they purchase mental health and other services and material goods needed to help them recover from their mental illness and remain outside of restrictive settings such as hospitals..

Design outcomes

Primary

MeasureTime frameDescription
Recovery From Mental IllnessStudy entry (pre-intervention), 12 months later (midpoint of intervention), & 24 months later (end of intervention)This outcome is measured by the Recovery Assessment Scale (RAS). Recovery is a psychosocial outcome assessed via patient self-ratings on a 41-item scale using a 5-point Likert-Response format ranging from strongly disagree to strongly agree. The minimum value for the RAS is 41 and the maximum is 205, with higher scores indicating a better outcome. Dimensions of recovery include personal confidence and hope, willingness to ask for help, goal and success orientation, reliance on others, and not being dominated by one's residual psychiatric symptoms.

Secondary

MeasureTime frameDescription
Coping MasteryStudy entry (pre-intervention), 12 months later (midpoint of intervention), & 24 months later (end of intervention)Change in subjects' sense of personal control over important life outcomes as measured by the Coping Mastery Scale. Higher values equal better coping mastery. Minimum = 2 and maximum = 49.
Perceived Autonomy SupportStudy entry (pre-intervention), 12 months later (midpoint of intervention), & 24 months later (end of intervention)Perceived support for autonomously motivated change measured by the Learning Climate Questionnaire of Williams & Deci. Measures change in perception that service environment is supportive of autonomy to make decisions and choices. Higher score equals better autonomy support. Minimum = 4 and maximum = 105.
Change in Self-esteemStudy entry (pre-intervention), 12 months later (midpoint of intervention), & 24 months later (end of intervention)Feelings of self-worth and confidence in general abilities as measured by the Rosenberg Self-Esteem Scale . Higher vales equal better self=esteem. Minimum = 10 and maximum = 40.
Number of Participants Enrolled in ClassesStudy entry (pre-intervention), 12 months later (midpoint of intervention), & 24 months later (end of intervention)Change in education participation status as measured by U.S. Department of Education's definition of school enrollment: enrolled in classes requiring registration and fee payment versus not enrolled in classes. Higher value = enrolled in classes. Minimum = 0 and maximum = 1.
Change in Mental Health Service CostFirst 12 months of study participation; Second 12 months of study participation; total 24 months of study participationMental health service cost is measured by the amount of reimbursement for a paid claim from the Texas Department of State Health Services Data Warehouse, It represents the amount of dollars paid for delivery of a discrete behavioral health service. Higher value = higher cost. Minimum = 1 and maximum = 5,493.
Number of Participants With EmploymentStudy entry (pre-intervention), 12 months later (midpoint of intervention), & 24 months later (end of intervention)Change in employment status as measured by Bureau of Labor Statistics definition of paid employment: with paid employment versus without paid employment. Higher value equals with paid employment. Minimum = 0 and maximum = 1.

Participant flow

Recruitment details

Eligible participants ( who were active Texas Department of State Health Services (DSHS) were recruited at community mental health agencies by local research staff between March 2009 and September 2010.

Participants by arm

ArmCount
Self-directed Care
Subjects receive traditional behavioral health and non-traditional services via a self-directed care model in which they develop a person-directed plan and create a budget for the purchase of medically necessary goods and services. Program staff acting as service brokers help them secure needed goods and services from within or outside the public behavioral health provider system. A fiscal intermediary manages financial resources to pay providers and enable the purchase of approved goods.. Self-directed care: Traditional and non-traditional behavioral health services are chosen from within and outside the public mental health system

Services as Usual
Subjects receive traditional behavioral health services as usual via the traditional service delivery system and its network of providers. Services as usual: Traditional behavioral health services are chosen from along those delivered at the patient's community mental health agency
