Evaluation of the Drug Use Disorders Identification Test (DUDIT) in Criminal Justice and Detoxification Settings and in a Swedish Population Sample

Psychometric properties of the 11-item self-report Drug Use Disorders Identification Test (DUDIT) were evaluated in a sample of heavy drug users from prison, probation, and inpatient detoxification settings, and in a general Swedish population sample. In the drug user sample, the DUDIT predicted drug dependence with a sensitivity of 90% for both DSM-4 and ICD-10 and a respective specificity of 78 and 88%. Reliability according to Cronbach’s α coefficient was 0.80. In the population sample, 3.1% scored positive on the DUDIT; T-score values are suggested. The DUDIT screens effectively for drug-related problems in clinically selected groups and may prove useful in the context of public health surveys.

A Test of the Validity of the Motivational Interviewing Treatment Integrity Code

To evaluate the Swedish version of the Motivational Interviewing Treatment Code (MITI), MITI coding was applied to tape‐recorded counseling sessions. Construct validity was assessed using factor analysis on 120 MITI‐coded sessions. Discriminant validity was assessed by comparing MITI coding of motivational interviewing (MI) sessions with information‐ and advice‐giving sessions as well as by comparing MI‐trained practitioners with untrained practitioners. A principal‐axis factoring analysis yielded some evidence for MITI construct validity. MITI differentiated between practitioners with different levels of MI training as well as between MI practitioners and advice‐giving counselors, thus supporting discriminant validity. MITI may be used as a training tool together with supervision to confirm and enhance MI practice in clinical settings. MITI can also serve as a tool for evaluating MI integrity in clinical research.

Coding Counsellor Behaviour in Motivational Interviewing Sessions: Inter‐Rater Reliability for the Swedish Motivational Interviewing Treatment Integrity Code (MITI)

The aim of this study was to evaluate inter‐rater reliability when using the Swedish version of the Motivational Interviewing Treatment Code (MITI) as an adjunct to MI training, clinical practice and research. Coders were trained to use the MITI for scoring taped sessions. The 4‐month basic training had a duration of 39 hours. Following training, 60 audio‐taped live interviews were randomly assigned for MITI coding. Mean intra‐class correlation (ICC) coefficients were calculated for 7 coders across all pairs of coders. Cronbachs alpha was calculated to estimate the covariance between each pair across their common interviews. Six months later, a second inter‐rater reliability test was performed, when 5 coders coded the same 15 randomly selected tapes. At the second reliability testing the mean ICC was 0.81 and the mean Cronbachs alpha was 0.96. However, the ICC varied for different sub‐variables of the MITI, ranging from 0.42 empathy to 0.79 for number of Closed questions. In conclusion, MITI shows promising potential to be a reliable tool to confirm and enhance MI training as well as practice in clinical settings and in evaluating MI integrity in clinical MI research. However, coder assessment of empathy and MI‐spirit, “global” variables, requires further refinement.

Alcohol habits in Sweden during 1997–2005 measured with the AUDIT

This study aimed to describe changes in Swedish alcohol habits during a period of “harmonization” with European Union alcohol policy. Three random samples collected during the years 1997 (n=997), 2001 (n=893) and 2005 (n=914) were compared. Alcohol habits and hazardous consumption was measured with the AUDIT (Alcohol Use Disorders Identification Test) distributed to the respondents by post. Results were somewhat diverse, but significant changes in alcohol habits occurred among two subgroups of the population: for women and the age group between 28 and 60 years, AUDIT scores peaked in 2001. The results are discussed in relation to the changes made in Swedish alcohol policy during the investigation period.

Validation of the Alcohol Use Disorders Identification Test and the Drug Use Disorders Identification Test in a Swedish sample of suspected offenders with signs of mental health problems: Results from the Mental Disorder, Substance Abuse and Crime study

Substance abuse is common among offenders. One method widely used for the detection of substance abuse is screening. This study explored the concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT) screening tools in relation to (a) substance abuse and dependency diagnoses and (b) three problem severity domains of the sixth version of the Addiction Severity Index in a sample of 181 suspected offenders with signs of mental health problems. The screening tools showed moderate to high accuracy for identification of dependency diagnoses. The AUDIT was associated with alcohol problem severity, whereas the DUDIT was associated with drug and legal problem severity. Administering the screening tools in the current population yields valid results. However, the suggested cutoff scores should be applied with caution due to the discrepancy between present and previous findings.

Internet-based assessment and self-monitoring of problematic alcohol and drug use

A Swedish web-based service (www.escreen.se) offers self-assessment and self-monitoring of alcohol and drug use via on-line screening with the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT) as well as in-depth risk assessment using extended versions of both tests (Alcohol-E and DUDIT-E). Users receive individualized feedback concerning their alcohol and drug consumption and can follow their alcohol and drug use over time in personal diagrams and by writing in an electronic diary. This study describes user characteristics, service utilization patterns, and psychometric test properties for 2361 individuals who created a valid account over 20 months starting in February 2007. Problematic alcohol use according to AUDIT criteria was indicated for 67.4%, while 46.0% met DUDIT criteria for problematic drug use. Men and women accessed the service equally, with a mean age of 23 years. Internal consistency reliability figures were 0.90 for 1846 first-time AUDIT users and 0.97 for 1211 first-time DUDIT users; among 213 second-time AUDIT users reliability was 0.93, and 0.96 for 97 second-time DUDIT users. Internet-based alcohol and drug monitoring could function as a self-help tool or as a complement to substance abuse treatment.

Population screening of risky alcohol and drug use via Internet and Interactive Voice Response (IVR) : A feasibility and psychometric study in a random sample

BACKGROUND The wide accessibility of computer-based technologies like the Internet and Interactive Voice Response (IVR) systems raises the question of whether population survey data could be collected more easily and cheaply compared to using paper questionnaires. In the area of possibly stigmatized behaviors such as problematic alcohol and drug use, the question extends to whether the prevalence of such behaviors in the general population could be surveyed without compromising the quality of the data. AIMS This study compares Internet and IVR versions of the AUDIT and DUDIT with respect to: (1) response rate, (2) problematic alcohol and drug use and (3) reliability. METHOD 5000 individuals, randomly selected from the Swedish general population, were contacted via postal mail and invited to complete the AUDIT and DUDIT questionnaires via Internet or IVR. In total, 1861 (37.8%) participated in the study, 1089 via Internet and 772 via IVR. RESULTS The Internet administration mode yielded a higher response rate (38.1%) compared to the IVR mode (33.9%). When respondents were given a choice between Internet and IVR, a higher response rate resulted (43.2-46.6%). Problematic alcohol and drug use occurred among 21.1% and 2.8% of the sample, respectively, with no significant differences by administration mode. Both the AUDIT and DUDIT exhibited satisfactory reliability across administration modes, Cronbachs α 0.76/0.86. CONCLUSIONS Data quality does not deteriorate with computerized administration methods for the AUDIT and DUDIT in population studies but paper questionnaires should also be made available to respondents in order to maximize response rates.

Alcohol Habits in Sweden during 1997–2009 with Particular Focus on 2005 and 2009, Assessed with the AUDIT: A Repeated Cross-Sectional Study

Aim: This study aimed to survey the changes in alcohol habits during a period with the European Union legal practices. Methods: Alcohol habits in Sweden were surveyed in the general Swedish population at four timepoints, in 1997, 2001, 2005 and 2009, using the 10-item AUDIT questionnaire. Design: Four separate randomly drawn cross-sectional samples of 1,250 individuals were surveyed at each timepoint. Results: An average of 70% of the sampled individuals responded to the AUDIT questionnaire. Men had higher total AUDIT scores than women in 2005 and 2009, but scores increased among women 61–71 years old and decreased among men 61–71 years old. Younger men and women 17–27 years old decreased their AUDIT-C consumption scores by almost 20% between 2005 and 2009. An analysis of problem drinkers (+8 for men/+6 for women) indicated that a larger proportion of elderly women drank moderately in 2009 compared with 2005, but fewer elderly women drank hazardously. Conclusions: Earlier increases in drinking levels between 1997 and 2001 may reflect a latent high demand that was restricted by low availability. When availability due to European Union harmonization increased, alcohol consumption followed suit. After a period of adaptation, alcohol consumption appears to have stabilized.

Single-Session Motivational Interviewing for Drug Detoxification Inpatients: Effects on Self-Efficacy, Stages of Change and Substance Use

Thirty-five inpatients at a Stockholm hospital drug user detoxification unit received single-session Motivational Interviewing (MI) between 2006 and 2008. At baseline and after 3 months, they were compared to a semirandomized control group of 52 patients with treatment as usual. In the MI group, self-efficacy increased regarding abstention in connection with positive feelings, appreciation of positive drug effects increased, and participants tended to transition toward preparation/action stages of change. Despite implementation challenges, the study demonstrates the feasibility and effectiveness of single-session MI delivery in the inpatient drug detoxification setting and suggests paths for future research on delivery of single-session MI.
