Development of Coercion Assessment Scale (CAS)
In this study, the investigators seek to further develop the CAS as a comprehensive, reliable, and valid instrument for measuring coercion to participate in research among adult substance abusing offender populations.
|Study Design:||Observational Model: Case-Only
Time Perspective: Cross-Sectional
|Official Title:||Improving Ethics in Research: Development of the Coercion Assessment Scale|
- Expand Scope of CAS Measure [ Time Frame: Months 9-30 ] [ Designated as safety issue: No ]To expand the scope of the CAS so that it can reliably and validly measure perceived coercion to enter research studies in a wide-range of substance abusing offender populations. The content domain will be expanded to include pressures experienced by individuals who have been arrested but not adjudicated (i.e., drug court clients), offenders who have been adjudicated but are not currently incarcerated (i.e., parolees/probationers) and offenders who are currently incarcerated.
- Ensuring CAS Use with Substance Abusing Offenders [ Time Frame: Months 9-30 ] [ Designated as safety issue: No ]To finalize the development of the CAS by ensuring that the instrument is appropriate for use with substance abusing offenders. Items on the instrument will be evaluated to ensure that they are correctly worded and that their intended meaning is accurately conveyed to participants.
- Evaluate Psychometric Properties of CAS [ Time Frame: Months 9-30 ] [ Designated as safety issue: No ]To evaluate the psychometric properties of the CAS to ensure that it is a reliable and valid measure of perceived coercion to participate in research. The psychometric evaluation will include an examination of test-retest reliability, internal consistency and factor structure, and convergent and discriminant validity.

There are no separate groups. All subjects are being asked to complete the CAS measure.
All clients will be asked to complete the CAS instrument.
First, the investigators wish to widen the scope of the CAS so that it can reliably and validly measure perceived coercion. The content domain will be expanded to included pressures experienced by a range of individuals involved in the criminal justice system. Second, the investigators will finalize the CAS by ensuring that the instrument is appropriate for use with substance abusing offenders. A final goal of the study examines the psychometric properties of the instrument. This evaluation will include an examination of test-retest reliability, internal consistency and factor structure, and convergent and discriminant validity.
This study will be carried out in three distinct phases to satisfy the goals detailed above. The purpose of Phase 1 is to add to the already existing content of the CAS. In this phase, focus groups will be conducted with clients (i.e., substance abusing offenders) and professionals (i.e., treatment and criminal justice staff and stakeholders) in several different criminal justice. The goal of these groups will be to identify additional sources of coercion that substance abusing offenders may experience related to participation in research. The purpose of Phase 2 is to finalize and ensure the appropriateness of the instrument. In this phase, the investigators will conduct a protocol analysis with 30 drug court clients. The interviewer will read each item aloud to participants, and participants will provide their response. After completing each item, they will be interviewed about how they arrived at their decision. The purpose of Phase 3 is to evaluate the psychometric properties of the CAS. A total of 200 substance abusing offenders participating in an ongoing NIDA-funded study (i.e., the "host study") will receive TRI's manualized written informed consent procedure as part of their participation in the host study. Following consent, research staff will administer study assessments to all consented participants. Additionally, a random sample of 50 clients will be selected to complete a retest interview, scheduled three to five days following the initial interview to assess the extent to which responses vary between the two administrations.
