Improving 24-month abstinence and employment outcomes for substance-dependent women receiving temporary assistance for needy families with intensive case management.

OBJECTIVE: We examined abstinence rates among substance-dependent women receiving Temporary Assistance for Needy Families (TANF) in intensive case management (ICM) over 24 months and whether ICM yielded significantly better employment outcomes compared with a screen-and-refer program (i.e., usual care). METHODS: Substance-dependent (n = 302) and non-substance dependent (n = 150) TANF applicants in Essex County, New Jersey, were recruited. We randomly assigned substance-dependent women to ICM or usual care. We interviewed all women at 3, 9, 15, and 24 months. RESULTS: Abstinence rates were higher for the ICM group than for the usual care group through 24 months of follow-up (odds ratio [OR] = 2.11; 95% confidence interval [CI] = 1.36, 3.29). A statistically significant interaction between time and group on number of days employed indicated that the rate of improvement over time in employment was greater for the ICM group than for the usual care group (incidence rate ratio = 1.03; 95% CI = 1.02, 1.04). Additionally, there were greater odds of being employed full time for those in the ICM group (OR = 1.68; 95% CI = 1.12, 2.51). CONCLUSIONS: ICM is a promising intervention for managing substance dependence among women receiving TANF and for improving employment rates among this vulnerable population.

Testing mechanisms of action for intensive case management.

AIM: This study identified factors that predict, mediate or moderate the effects of intensive case management (ICM) on longer-term drug abstinence outcomes in women on welfare. DESIGN: In a parent study women were assigned randomly to usual care (UC) or intensive case management (ICM). Treatment was provided for 12 weeks and follow-up continued for 15 months after study intake. A set of hypothesized mediators was assessed at month 3 and a rigorous four-step mediational model was tested using outcomes in months 4-15. PARTICIPANTS: Participants were 302 drug-dependent women applying and eligible for federal welfare and not currently in drug abuse treatment. Interventions ICM provided intensive treatment engagement including voucher incentives for treatment attendance and case management services; UC provided primarily referral to community treatment programs. MEASUREMENT: Substance use outcomes were assessed using the time-line follow-back interview and confirmed using biological and collateral measures. FINDINGS: Participants in ICM had more case manager contacts, better treatment engagement and more self-help attendance than did those in UC. Each of these variables predicted, and was shown to be a mediator of outcome, but case management contact was an especially robust mediator. Further, ICM effects were strongest for those who attended treatment least. Contrary to prediction, greater psychopathology and environmental stressors did not predict worse outcomes. CONCLUSIONS: Findings suggest that case management is an active intervention that may both facilitate and substitute for formal drug abuse treatment.

Effectiveness of intensive case management for substance-dependent women receiving temporary assistance for needy families.

OBJECTIVE: We tested the effectiveness of a long-term coordinated care strategy--intensive case management (ICM)--compared with usual care (UC) among a group of substance-dependent women receiving Temporary Assistance for Needy Families (TANF). METHODS: Substance-dependent women on TANF (N=302) were recruited from welfare offices. They were assessed and randomly assigned to ICM or UC; follow-up was at 3, 9, and 15 months. UC consisted of a health assessment at the welfare office and a referral to substance abuse treatment and TANF services. ICM clients received ICM services in addition to UC services. RESULTS: ICM clients had significantly higher levels of substance abuse treatment initiation, engagement, and retention compared with UC clients. In some cases, ICM treatment attendance rates were double those of UC rates. Additionally, almost twice as many ICM clients were abstinent at the 15 month follow-up compared with UC clients (P<.0025). CONCLUSIONS: ICM is a promising intervention for managing the chronic nature of substance dependence among women receiving TANF. Future research should refine long-term care strategies-such as ICM-that address the chronic nature of substance dependence among low-income populations.

Development of the OCDS--revised: a measure of alcohol and drug urges with outpatient substance abuse clients.

Urges to use substances is an important construct in understanding the maintenance of substance use as well as relapse. There is a need to evaluate single instruments measuring global urges to use substances (including alcohol). The Obsessive Compulsive Drinking Scale (OCDS; R. F. Anton, D. H. Moak, & P. Latham, 1995) was revised and tested as a single measure of urges to use substances. Participants were 252 adults entering outpatient substance abuse treatment. Results suggest that the revised scale (OCDS-R) primarily assesses 1 global factor for urges to use substances. In addition, strong support was found for the reliability and concurrent validity of the OCDS-R, although results for its predictive validity were mixed. The OCDS-R is a brief, psychometrically sound self-report instrument that has applicability within clinical and research settings.

Assessing consequences of substance use: psychometric properties of the inventory of drug use consequences.

Negative consequences are an important component of the substance use change process, yet no standardized measure exists to assess consequences of use. This study evaluated the psychometric properties of the Inventory of Drug Use Consequences, a self-report measure assessing drinking and drug use consequences. Participants (N=252) were assessed at entry into outpatient substance abuse treatment. Items loaded strongly on 1 factor, and internal consistency of the total scale was high. Fifteen items with the highest correlations with the total scale were chosen to represent the construct. The shortened measure exhibited good internal consistency, convergent and discriminant validity, and detected change over time and may be the measure of substance use consequences that is lacking in the field.

Examining mechanisms of action in 12-Step community outpatient treatment.

Twelve-step theory hypothesizes that changes in specific cognitions and behaviors, including adoption of disease model beliefs and involvement in self-help programs, lead to symptom reduction. We examined the role of self-help affiliation in treatment outcome using causal chain analysis. Baseline, end-treatment and follow-up self-help affiliation and substance use were assessed in 252 drug and alcohol abusers attending a community program. Participants were randomly assigned to one of three cognitive-behavioral or 12-Step oriented individual counseling conditions. Participants also were assigned, based on problem severity, to one of three treatment settings (partial hospitalization; intensive outpatient; standard outpatient) that varied according to intensity of additional 12-Step programming. Repeated-measures ANOVA indicated that self-help affiliation increased overall during treatment, particularly in the 12-Step counseling condition (versus cognitive-behavioral), and the partial hospitalization setting (versus standard outpatient). Multiple regression indicated that self-help affiliation was negatively associated with substance use 6 months post-treatment, and that this was not moderated by condition. Self-help affiliation predicted outcome most strongly in the partial hospitalization setting and not at all in outpatient; however, this effect was accounted for by participants' initial problem severity: high-severity patients had poorer outcomes if they failed to increase self-help affiliation, relative to those who increased affiliation and to low-severity patients regardless of affiliation. Results indicate that, in this community-based program, self-help affiliation increased as a function of exposure to 12-Step oriented treatment programming, and significantly predicted better outcome among patients with high levels of problem severity. Implications for future treatment process and dissemination research are discussed.

Health-related quality of life for adults participating in outpatient substance abuse treatment.

Interest exists in assessing health-related quality of life as one aspect of treatment effectiveness with substance abuse clients. The SF-36 Health Survey is a self-report measure assessing subjective health status along physical and mental health dimensions. Subjects were 252 adults in an outpatient, randomized clinical trial for substance abuse treatment. Subjects reported significantly more impairments in functioning when compared to U.S. population norms, but differences disappeared after three months of treatment. There was little support that quality of life functioning was significantly related to substance use during treatment. Results highlight the importance of using the SF-36 to facilitate treatment planning.

Motivational subtypes and continuous measures of readiness for change: concurrent and predictive validity.

This study compared the concurrent and predictive validity of motivational subtypes versus a continuous measure of readiness for change as measured by the University of Rhode Island Change Assessment Scale (URICA; E. A. McConnaughy, J. O. Prochaska, & W. F. Velicer, 1983) in 252 individuals participating in a substance abuse treatment study (38% female; mean age = 36). Hierachical cluster analysis identified a 2-cluster solution. Consistent with previous research, both the motivational subtypes and the continuous readiness measure exhibited good concurrent validity with both baseline characteristics and change process variables. Neither readiness-for-change measure predicted end treatment outcomes. Measures of readiness for change based on the URICA exhibit limited clinical utility, because they are not able to predict future behavior.

Barriers to employability among substance dependent and nonsubstance-affected women on federal welfare: implications for program design.

OBJECTIVE: This study examined barriers to employability among women meeting criteria for a substance dependence disorder who were identified by routine screening conducted in welfare offices. The characteristics of these women were compared to other women on welfare who did not have a substance use disorder. METHOD: A sample of 214 substance dependent women on federal welfare were recruited to participate in a substance use disorders welfare demonstration project. An additional 69 nonsubstance-affected women on welfare served as a comparison sample. All participants were assessed in welfare settings through a standardized battery of measures. RESULTS: Substance dependent women reported moderate to severe substance use problems. They also reported significantly higher rates than the women with no substance use disorder of other barriers such as domestic violence, mental health problems, legal problems, child welfare investigations and fewer job skills. CONCLUSIONS: Findings raise questions about the likely effectiveness of existing welfare reform services in addressing the needs of substance dependent women.

Examining mechanisms of action in 12-step treatment: the role of 12-step cognitions.

OBJECTIVE: Twelve-step treatment appears to be modestly effective in treating alcohol and cocaine dependence, but little is known about its mechanisms of action. The primary aim of this study was to examine the hypothesized mechanism of action of 12-step cognitions. In addition, the psychometric properties of a measure used to assess 12-step cognitions were tested. METHOD: The psychometric properties of a measure to assess 12-step cognitions were examined in a sample of individuals (N = 370, 61% male) seeking inpatient (n = 118) or outpatient (n = 252) 12-step-oriented community treatment. Additional analyses of data from the inpatient sample examined changes in cognitions from entry to discharge and 12-month follow-up. The univariate and multivariate relationship of cognitions at discharge, and substance use outcomes across the 12-month follow-up were also examined in the inpatient sample. RESULTS: The measure of 12-step cognitions demonstrated good internal consistency. Findings supported some, but not all, of the hypothesized active ingredients of 12-step treatment. Cognitive processes common to many treatment-approaches significantly mediated outcomes, whereas processes unique to the 12-step approach (e.g., spirituality) did not. Overall, some 12-step cognitions at discharge were good predictors of outcome, explaining as much variance in outcome as illness severity factors (e.g., dependence severity). CONCLUSIONS: Results provided greater support for 12-step treatment theory than those reported in prior studies. At the same time, findings suggest that diverse treatment approaches may operate through a common set of active ingredients.
