The purpose of our project was to develop and empirically test a diagnostic instrument which would permit sufficiently reliable differentiation between alcoholics and healthy as well as sick persons and which would also be easy and economical to administer. For this purpose, roughly 250 diagnostically relevant items were selected from the extensive literature on alcoholism and, with a total of 1335 patients (661 of these were alcoholics), were evaluated in three separate phases for their ability to differentiate. The best items were selected on the basis of various statistical criteria and then cross-validated. The result is the Munich Alcoholism Test (MAT) which consists of two complementary parts: a 7-item physicians assessment part and a 24-item self-assessment part. In a cross-validation study on 675 unselected in- and outpatients a validity of r = 0.94 was obtained. The reliability of the self-assessment part was r = 0.84.

Seven patients (0.5%) died after discharge; their data were excluded from the recorded response rate and the figures on which all analytical calculations were based. We have evaluable data for 84.5% of the patients who signed the original written consent on their admission to in-patient treatment. Those who dropped out of therapy are included.

Introduction: Cognitive impairment has been reported in drug-dependent patients under opioid maintenance treatment. Objectives: To compare cognitive functioning in healthy controls and in opioid-dependent patients treated with Buprenorphine, Heroin, or methadone maintenance. Methods: We used the standardized test battery ART-90 to study cognitive function in patients under long-term heroin treatment (n = 20), Bup (n = 22), or Met (n = 24) maintenance treatment and healthy controls (n = 25). Results: Patients receiving heroin performed significantly worse than healthy controls in most domains. Heroin patients performed worse than patients in the other two treatment groups in subtests measuring psychomotor performance under stress conditions and monotony. Conclusions and Scientific Significance: Although a number of limitations must be taken into account, this study provides some preliminary evidence that cognitive function may be more impaired in patients under heroin maintenance treatment than in patients receiving Bup or Met and in healthy controls.

Ziel: Die Erstellung von Leitlinien zur Postakutbehandlung bei Storungen durch Opioide. Methode: Bis einschlieslich 2003 wurden in 7 Datenbanken Literaturrecherchen uber klinische Studien zur Substitution, zur abstinenzorientierten, medikamentosen, psychosozialen und zur forensischen Behandlung gesucht. Die Erstellung der Leitlinien erfolgte nach den Richtlinien des Leitlinienmanuals der Arztlichen Zentralstelle fur Qualitatssicherung (AzQ)und der AWMF sowie entsprechend den Kriterien des Ratings wissenschaftlicher Publikationen des Scottish Intercollegiate Guidelines Network. Ergebnis: Es wurde ein konsentiertes Leitlinien-Kapitel uber »Postakutbehandlung bei Storungen durch Opioide« mit Evidenzeinschatzungen und entsprechenden Empfehlungen erstellt. Schlussfolgerungen: Vorerst formulierte Expertenmeinungen sollten in naher Zukunft unter Wahrung ethischer Grenzen durch Resultate entsprechender Forschungsarbeiten ersetzt werden.

SummaryThis short questionnaire for alcoholics (KFA) has so far been used as an aid for the clinical diagnosis of alcoholism. In the presented empirical study the KFA was tested on its efficiency as an independent diagnostic instrument for the identification of alcoholics. The questionnaire was given to 120 male alcoholics and 80 male controls (nonalcoholic inpatients). Its validity (correlation of test scores by independent criterion) of r=0.81 with a reliability of r=0.94 is fairly high, considering the nature of our control group being inpatients in contrast to the normally used healthy controls. A further improvement of discrimination could be achieved in weighting certain items. On this basis given a cutting score of 6 points the misclassifications in both alcoholics and controls could be reduced to 4%. Allowing this error rate the KFA can be considered a suitable test for the identification of alcoholics.ZusammenfassungDer Kurzfragebogen für Alkoholgefährdete (KFA) wurde bisher als Ergänzung zur klinischen Diagnosestellung angewandt. In der vorliegenden empirisch-statistischen Untersuchung wurde geprüft, ob der KFA sich als eigenständiger Test zur Diagnosestellung von Alkoholismus eignet. Insgesamt wurden 120 männliche Alkoholiker und 80 Kontrollpatienten untersucht. Durch einfache Summenwertbildung der Ja-Antworten erreicht der Fragebogen eine Validität von r=0,81 (Korrelation mit dem Außenkriterium der Diagnose) bei einer Reliabilität von r=0,94, was unter Berücksichtigung der besonderen Kontrollstichprobe (somatisch Kranke im Gegensatz zu sonst üblichen gesunden Kontrollpersonen) relativ hoch erscheint. Eine weitere Verbesserung der Validität und damit Trennfähigkeit des Fragebogens läßt sich durch Gewichtung einiger Items erreichen: Bei einem Trennwert von 6 Punkten ergibt sich eine Fehlklassifikation von 4% bei den Alkoholikern und 4% bei den Nichtalkoholikern. Der KFA erscheint damit bei einer vertretbaren Fehlerrate als Test zur Identifikation von Alkoholikern geeignet.

Fragestellung: Der MATE (Measurements in the Addictions for Triage and Evaluation) ist ein Interview, mit dem relevante Kriterien fur die Behandlungszuweisung und ‑evaluation im Suchtbereich erfasst werden konnen. Ziel dieser Pilotstudie war die Ermittlung der psychometrischen Eigenschaften der deutschen Version des MATE. Gepruft wurden seine Dimensionalitat, Interrater-Reliabilitat, Konstruktvaliditat und die Anwendbarkeit. Methode: Zwischen Juli 2006 und Marz 2007 wurden MATE-Interviews mit 291 alkohol- oder drogenabhangigen Patienten in drei Kliniken mit ambulanter und/oder stationarer Behandlung durchgefuhrt. Die Interviewer waren trainierte Studierende der Psychologie. Im Abstand von maximal 14 Tagen nach dem ersten MATE-Interview fuhrte ein anderer Interviewer entweder ein zweites MATE-Interview (N = 74) oder ein Validierungsinterview (N = 138) durch. Nach jeder Durchfuhrung eines MATE-Interviews beantworteten die Interviewer einen Fragebogen zur Anwendbarkeit des MATE. Ergebnisse: H...

This study examines the relationship between (alcohol specific) self-efficacy expectancies and abstinence from alcohol measured at 3 follow-ups (t1 = 6, t2 = 12 and t3 = 24 months after treatment) in 3 groups of patients with different severity levels of their alcohol dependency. N = 169 patients were included (n = 65 outpatient treatment, n = 51 inpatient short-term and n = 53 inpatient long-term treatment). Self-efficacy was measured using the Alcohol Abstinence Self-Efficacy Scale (AASE). Treatment outcome was defined as complete abstinence from alcohol at time of follow-ups. The AASE differentiates reliably between abstinent and non-abstinent patients in each treatment group at the 3 follow-ups. Abstinent patients had significant higher scores in both of the two subscales confidence and temptation. The strongest relationship between AASE and treatment outcome could be found for subjects in short-term inpatient treatment. The impact of the results for clinical practice is discussed.

Fragestellung: Neben der Behandlungsallokation (Triage) ist eine wesentliche Aufgabe des Instruments Measurements in the Addictions for Triage and Evaluation (MATE) die Anwendung in der Evaluation in Therapieverlauf und Katamnese. In diesem Aufsatz werden daher Anderungssensitivitat und prognostische Validitat des MATE auf den beiden Ebenen der Mittelwerts- wie der individuellen Veranderungen gepruft. Hinzu kommt die Frage der prognostischen Aussagefahigkeit der MATE-Indizes hinsichtlich der Abstinenz. Methodik: Bei einer Teilstichprobe (n=113) aus dem deutschen MATE Projekt wurde der MATE in einer Suchtfachklinik zur Entwohnungsbehandlung fur alkoholabhangige Patienten zu Beginn und am Ende der Behandlung eingesetzt. Auserdem wurden katamnestische Daten einer Routinekatamnese nach einem Jahr erhoben. Fur die Pra-Post-Differenzen der MATE-Scores berechneten wir Cohen’s d sowie das Standardized Response Mean (SRM). Daruber hinaus ermittelten wir die Verteilung individueller Veranderungen anhand der...

The investigation was carried out in a representative sample of subjects of the Federal Republic of Germany, including West Berlin (n = 1952). The subjects were 20--64 years old. The following were investigated: 1. Social and abusive drinking patterns 2. Relations between drinking behavior and sociodemographic data 3. Relations between drinking behavior and subjective feeling. Of the subjects, 47% consumed alcohol daily or several times a week, 6% called themselves teetotallers. Beer was the preferred beverage. The drinking behavior varied among income classes and vocational groups. Of the whole sample, 8% drank regularly whilst working; 25% of the skilled workers did so. Comparing alcohol consumption and subjective feeling, there was a slight association between elevated mood and frequent alcohol consumption. Of the subjects, 4% were identified as alcohol misusers (7% of the males, 1% of the females). Persons at high risk were men living alone (especially widowed and divorced subjects) and persons of medium income. Regular consumers of hard liquor were at higher risk than consumers of beer or wine. The highest percentage of misuse was found among unskilled and skilled workers and among inhabitants of large cities. There was a slight association between high alcohol misuse index and depressive states, subjective complaints, and paranoid attitudes.
