Readiness for mental health treatment and for changing alcohol use in patients with comorbid psychiatric and alcohol disorders: are they congruent?

Project INTEGRATE: An integrative study of brief alcohol interventions for college students

This article provides an overview of a study that synthesizes multiple, independently collected alcohol intervention studies for college students into a single, multisite longitudinal data set. This research embraced innovative analytic strategies (i.e., integrative data analysis or meta-analysis using individual participant-level data), with the overall goal of answering research questions that are difficult to address in individual studies such as moderation analysis, while providing a built-in replication for the reported efficacy of brief motivational interventions for college students. Data were pooled across 24 intervention studies, of which 21 included a comparison or control condition and all included one or more treatment conditions. This yielded a sample of 12,630 participants (42% men; 58% first-year or incoming students). The majority of the sample identified as White (74%), with 12% Asian, 7% Hispanic, 2% Black, and 5% other/mixed ethnic groups. Participants were assessed 2 or more times from baseline up to 12 months, with varying assessment schedules across studies. This article describes how we combined individual participant-level data from multiple studies, and discusses the steps taken to develop commensurate measures across studies via harmonization and newly developed Markov chain Monte Carlo (MCMC) algorithms for 2-parameter logistic item response theory models and a generalized partial credit model. This innovative approach has intriguing promises, but significant barriers exist. To lower the barriers, there is a need to increase overlap in measures and timing of follow-up assessments across studies, better define treatment and control groups, and improve transparency and documentation in future single intervention studies.

Changes in motivation for treatment in precontemplating dually diagnosed patients receiving assertive community treatment

In a population of dually diagnosed patients receiving assertive community treatment we used the theoretical framework of the transtheoretical model to establish (a) the proportions and characteristics of patients who were not motivated for treatment for psychiatric symptoms and substance use, (b) the proportion of patients who moved towards behavioral change after about 1 year, and examine how this change was related with clinical outcome; and (c) the sequence of change processes. Chi square tests and T tests were used to compare the patient characteristics and outcomes of patients who remained in precontemplation with those who progressed. During follow-up, 47 % of the patients came out of the precontemplation phase for treatment of psychiatric symptoms and 38 % for substance use behavior. Those who remained in precontemplation benefited less from treatment. Of those who did move forward, most appeared to become motivated for psychiatric treatment before becoming motivated to reduce substance use.

Risk factors for drinking among HIV-positive African American adults: the depression-gender interaction

BACKGROUND

Alcohol misuse disproportionately affects people living with HIV. People who struggle with alcohol are also likely to be concurrently struggling with depression. Although there is evidence linking depression to HIV, depression to alcohol, and alcohol to HIV, there is limited research that simultaneously examines the interlocking associations between all three factors.

OBJECTIVE

To investigate the interaction between depression symptomatology and gender on alcohol misuse, while controlling for motivation to reduce drinking, among HIV-positive African Americans. This population was examined because of their increased for developing alcohol dependence.

METHODS

Data analysis was conducted on baseline survey data of HIV-positive African American adults (N = 88) who drink and were enrolled in the Project PLUS (Positive Living through Understanding and Support) intervention to examine the correlates (i.e., gender, motivation, depression) of drinking in the past 30 days.

RESULTS

Hierarchical linear regression analysis showed a significant interaction between gender and depression to predict total drinks reported (R(2) = .56, p < .001). While depression was the sole predictor of drinking for men and suppressed the role of motivation, the reverse was true for women; depression was not a significant predictor after controlling for motivation to reduce drinking.

CONCLUSION

African American men and women living with HIV have different risk factors for recent drinking.

SCIENTIFIC SIGNIFICANCE

Understanding the link between depression, gender, and motivation to reduce drinking for HIV-positive adults with alcohol problems is crucial for the development of gender and culturally relevant treatments.

Readiness to change drinking behavior in female college students

OBJECTIVE

Motivational interviewing (MI) therapies are effective in reducing high-risk drinking in college populations. Although research supports efficacy of MI prevention strategies in reducing alcohol use, there are little data examining readiness to change (RTC), the underlying theoretical model of MI interventions. The purpose of the present study was to explore RTC variability and drinking behavior and whether MI increases RTC in an intervention group compared with controls.

METHOD

Two-hundred eighty-five first-year female college students participated in the study. Present analyses focused on those students who consumed alcohol in the month before the study (n = 182). RTC was measured using the Readiness to Change Ruler.

RESULTS

Analyses were conducted using hierarchical linear modeling. There was significant variability in RTC: 71.86% of variance in RTC was between-person differences, and 28.14% was within-person differences. Higher RTC was associated with lower intentions to drink and future drinking behavior. However, in weeks in which students drank more, they experienced a decrease in RTC. Based on the significant cross-level interaction, the intervention group had significantly higher RTC than controls.

CONCLUSIONS

These results provided partial support for our hypotheses. The overall theoretical construct of RTC varies both across and within individuals. These results also offer support for the utility of MI-based prevention strategies in increasing RTC within individuals. However, we did not consistently find that these changes related to drinking changes. Findings provide support for both the construct of RTC and utility of MI interventions in changing these beliefs in female college students.

Motivation and the stages of change among individuals with severe mental illness and substance abuse disorders

A complicating factor affecting the treatment of individuals with coexisting substance use problems and serious mental illness is their motivation for change and how these interacting, chronic conditions affect the entire process of intentional behavior change. This selective review explores conceptual and assessment issues related to readiness to modify substance use and readiness to initiate behaviors helpful for managing mental illness in the search for a better understanding of patient motivation for change. The recent but limited research on motivation and stages of change among dually diagnosed patients indicates that these individuals appear to access and use an intentional behavior change process. However, it is not completely clear how this process works and what precise adaptations are needed to assess and to access motivation to change to encourage sustained behavior change in this population. Nevertheless, motivation and readiness to change are important dimensions that need to be addressed in treatment and research with dually diagnosed populations.

Assessment of motivation to change substance use in dually-diagnosed schizophrenia patients

Assessment of motivation to change substance use can be helpful in evaluating treatment readiness and outcome. However, the utility of self-report measures of motivation with schizophrenia patients is questionable. In the current study patients with schizophrenia and either concurrent cocaine dependence or remitted dependence completed the University of Rhode Island Change Assessment-Maryland (URICA-M), a self-report inventory that assesses motivation, and an analogous cartoon instrument at baseline and 6-months follow-up. Results demonstrate that the cartoon readiness to change score was related to increased treatment utilization and decreased substance use; results were not as favorable for the URICA-M. Findings suggest that the cartoon measure may be a suitable alternative to assess motivation to change substance use with cognitively impaired patients.

Intention to utilize formal help in a sample with alcohol problems: a prospective study

BACKGROUND

Studies investigating factors of treatment entry have predominantly focussed on persons that have already taken an initial step in the process of help-seeking. With particular emphasis on intention to utilize help, this study aims to detect predictors for alcohol-related help-seeking among a non-help-utilizing sample.

METHODS

Using 312 individuals with diverse alcohol problems (dependence, abuse, at-risk drinking), intention to utilize help was assessed in addition to evidence based predictors for utilization of help (e.g. severity of alcohol problem, prior help-seeking).

RESULTS

In addition to prior utilization of help (OR=9.76, CI: 4.60-20.74) and adverse consequences from drinking (OR=1.13, CI: 1.02-1.25), intention to utilize help (OR=4.84, CI: 2.04-11.51) was a central predictor for help-seeking. Among individuals who had not obtained prior help, individuals intending to seek help were 8.7 times more likely to utilize help than those not intending to seek help (CI: 1.05-72.2).

CONCLUSIONS

In the past, intention to utilize help has been neglected from models investigating treatment entry. This study's findings show that intention is a central factor for utilization of alcohol-specific formal help. Consequently, brief interventions focusing on enhancing motivation are expected to improve early help-seeking among general hospital patients with diverse alcohol problems.
