Tracking and Locating Itinerant Subjects With a Rechargeable Incentive Card: Results of a Randomized Trial.

BACKGROUND: High attrition among research participants undermines the validity and generalizability of field research. This study contrasted two incentivizing methods--money orders (MOs) or rechargeable incentive cards (RICs)--with regard to rates of participants' study engagement and follow-up contact over a 6-month period. METHODS: Substance abusers (N = 303) in Los Angeles, California were recruited and randomized to either an MO (control) or RIC (experimental) condition. All participants were asked to call the researchers at the beginning of each calendar month for the ensuing 5 months to update their locator information, even if nothing had changed. Each call resulted in a $10 payment, issued immediately via the RIC system or by MO by mail. Research staff located and interviewed all participants at Month 6. Contact logs assessed level of effort required to locate participants and conduct follow-up interviews. RESULTS: Relative to controls, RIC participants, especially those with low ability to defer gratification, initiated more monthly calls. Six-month follow-up rates did not differ between RIC (75%) and controls (79%), though the RIC condition was associated with an average staff time savings of 39.8 minutes per study participant. DISCUSSION: For longitudinal public health research involving itinerant study participants, the RIC method produces a modest benefit in study engagement and reduced staff time devoted to participant tracking and payments. However, the overall cost-effectiveness of this approach will depend on the pricing model of the card-issuing vendor (which in turns depends on the scale of the project, with per-unit costs falling for larger projects).

Effectiveness of Using Incentives to Improve Parolee Admission and Attendance in Community Addiction Treatment.

This study is a randomized effectiveness trial of the use of incentives to improve treatment utilization among parolees in community treatment. In prison, Admission phase parolees were randomized to Admission Incentive (N=31) or Education (N=29). Attendance phase parolees entering community treatment were randomized to Attendance Incentive (N=104) or Education (N=98). There was no main effect for incentives in either study phase. Neither admission to community treatment (Incentive 60%, Education 64%; p =.74), nor intervention completion (Incentive 22%; Education 27%; p =.46) appeared to be impacted. Time-in-treatment was predicted by age, first arrest age, and type of parole status (Cox regression p<.05), but not by treatment group. Providing incentives did not increase the likelihood that parolees enrolled in or stayed in community treatment. In light of this finding, criminal justice practitioners who are considering incentives to increase admission or retention should be aware that they may not produce the desired outcomes.

An Experimental Comparison of Telepsychiatry and Conventional Psychiatry for Parolees.

OBJECTIVE: Many offenders treated for psychiatric disorders while incarcerated are paroled to counties where psychiatric care is limited, leading some correctional departments to offer psychiatric treatment via videoconferencing ("telepsychiatry"). However, the effectiveness of telepsychiatry for offenders with psychiatric disorders has not been rigorously evaluated. METHODS: In this randomized field experiment, the authors compared the effectiveness of telepsychiatry and in-person psychiatric sessions (treatment as usual) among 71 parolees receiving outpatient psychiatric treatment over a six-month period. Satisfaction with treatment, therapeutic alliance, medication adherence, and psychological functioning were measured. Follow-up data were collected from 60 of the 71 (85%) patients (N=20, telepsychiatry; N=40, control condition). RESULTS: Findings revealed high satisfaction with telepsychiatry overall and no significant group differences in medication adherence or psychological functioning. However, telepsychiatry patients reported lower levels of therapeutic alliance at follow-up. CONCLUSIONS: Telepsychiatry appeared to be an acceptable and effective approach for providing psychiatric care for this population.
