Do patient intervention ratings predict alcohol-related consequences?

Little is known about treatment process for behavior change for brief interventions. Patient ratings of treatment process during a patient-centered brief intervention for alcohol were used to predict post-treatment alcohol use and consequences. We use data from a randomized clinical trial that compared the effects of BI (1 session) to BI and booster (BIB, 2 sessions) to reduce harmful drinking and alcohol consequences. Subjects were n=167 (BI) and n=82 (BIB). Five of the 12 ratings were rated significantly higher by those in the BIB condition compared to BI. The only predictor of reduced alcohol consequences at 12-months was higher ratings of, "I have obtained some new understanding," for BIB participants (t=-2.50, p<.05). Patient perspectives on treatment may have a role in patient outcomes and should be explored as a dimension of treatment process.

Can the short index of problems (SIP) be improved? Validity and reliability of the three-month SIP in an emergency department sample.

OBJECTIVE: Although the Short Index of Problems (SIP) is often used, little is known about the psychometric properties of the SIP in special populations. The present study seeks to determine the following: (1) whether it is possible to substitute items to enhance the psychometric properties of the SIP and (2) whether the SIP, or improved scale, is as sensitive as the Drinker Inventory of Consequences (DrInC) to assess intervention effectiveness. METHOD: The sample consisted of 404 injured patients who were treated in the Emergency Department (ED) of a major teaching hospital that serves southern New England. Three approaches were used to guide development of the 3-month SIP-R, the potential alternative to the SIP. Cronbach's alpha assessed intrascale reliability; hierarchical multiple regression assessed construct validity; performance of the scales assessing intervention change were compared to the total 3-month DrInC as a function of intervention using analysis of covariance (ANCOVA). RESULTS: There was no evidence that changing the current SIP items will significantly improve performance. The 3-month SIP performed as well as the 3-month DrInC-2R in predicting 12-month DrInC scores and in determining intervention change at 12 months. Of the 45 DrInC items, 31 also predicted a difference across intervention groups. CONCLUSIONS: These results suggest there is no advantage to changing the current SIP items. The 3-month SIP is a psychometrically sound measure for assessing consequences of alcohol consumption in an ED sample and is almost as sensitive to intervention change as the full DrInC.

Research fundamentals: follow-up of subjects in clinical trials: addressing subject attrition.

Many published clinical trials have less than adequate follow-up. When conducting a clinical trial, researchers attempt to minimize data loss; however, some data may not be collected, particularly when subjects are lost to follow-up. Careful planning of research protocols, including comprehensive initial data collection, identification of locators, flexible scheduling, systematic subject tracking, monitoring subject loss, and systematically approaching problem cases can ensure high follow-up rates. This article presents a compendium of techniques and procedures that researchers can use to enhance follow-up and address attrition in their studies. Finally, this article outlines statistical techniques that can be used to address the effects of missing data, particularly when patients are lost to follow-up.

Marijuana use and prior injury among injured problem drinkers.

OBJECTIVES: The purpose of this paper is to better understand marijuana use among injured problem drinkers in the emergency department (ED). The specific objectives are: 1) to assess the prevalence of marijuana use; 2) to identify factors associated with marijuana use; 3) to determine whether prior injury is associated with marijuana use; and 4) to determine whether marijuana-using problem drinkers want to change behaviors. METHODS: The authors conducted a post-hoc analysis on data obtained prospectively. Subjects had injury and problem drinking: either measurable alcohol level (blood alcohol concentration, BAC), report of drinking, or an Alcohol Use Disorders Identification Test (AUDIT) score of > or =8. The study was conducted on weekend nights; 3,776 injured ED patients were screened, 383 refused, 578 were enrolled, and 433 had complete data. RESULTS: Of the 433 subjects, 48.3% reported using marijuana in the three months prior. Marijuana-using problem drinkers had more hazardous drinking, higher AUDIT scores (14.0 vs. 11.4, p < 0.001), and higher risk-taking scores (12.4 vs. 10.1, p < 0.001). More used other drugs (69.7% vs. 30.3%, p < 0.001). In regression analyses, marijuana use remained an independent predictor of prior injury (OR = 2.16, 95% CI = 1.25 to 3.75), particularly prior alcohol-related (OR = 2.26, 95% CI = 1.45 to 3.53) and motor-vehicle-related (OR = 1.69, 95% CI = 1.03 to 2.79) injury. Readiness-to-change scores were similar (4.14 vs. 4.22, p = 0.21) between users and nonusers. CONCLUSIONS: Marijuana use among injured problem drinkers is prevalent. Their risk of prior injury is increased. Counseling for alcohol and injury should address marijuana use.

Treatment completion in a brief motivational intervention in the emergency department: the effect of multiple interventions and therapists' behavior.

BACKGROUND: The aim of this study was to identify therapist behaviors during a brief motivational intervention (BMI) given to injured emergency department patients that predicted participant return for a second BMI session and 12-month alcohol-related outcomes. METHOD: This was a secondary data analysis of a randomized controlled trial (n = 539) previously demonstrating that random assignment to a BMI and booster session resulted in a significant reduction of 12-month post-intervention alcohol-related injuries and negative consequences relative to standard care. RESULTS: Participants who actually received 2 BMI sessions had significantly less alcohol-related negative consequences than those who received only 1 BMI session. Therapists who reported a higher focus on emotional support and low focus on participant drinking behaviors during the initial BMI session were more likely to have assigned participants return for the second BMI session. CONCLUSION: The results of these secondary analyses show that compliance with a 2-session therapeutic intervention (BIB) predicted fewer negative alcohol-related consequences, and that therapists' supportive emotional emphasis during the first BMI session was important in predicting participants returning for the second MI session.
