BACKGROUND: Motivational interviewing has been shown to be broadly usable in a scientific setting in the management of behavioural problems and diseases. However, data concerning implementation and aspects regarding the use of motivational interviewing in general practice is missing. AIM: To evaluate GPs' conception of motivational interviewing in terms of methods, adherence to and aspects of its use in general practice after a course. STUDY DESIGN: In a randomised controlled trial concerning intensive treatment of newly diagnosed patients with type 2 diabetes detected by screening, the GPs were randomised to a course in motivational interviewing or not. The study also included a third group of GPs outside the randomised controlled trial, who had 2 years previously received a similar course in motivational interviewing. SETTING: General practice in Denmark. METHOD: The intervention consisted of a 1.5-day residential course in motivational interviewing with 0.5-day follow-ups, twice during the first year. Questionnaire data from GPs were obtained. RESULTS: We obtained a 100% response-rate from the GPs in all three groups. The GPs trained in motivational interviewing adhered statistically significantly more to the methods than did the control group. More than 95% of the GPs receiving the course stated that they had used the specific methods in general practice. CONCLUSION: A course in motivational interviewing seems to influence GPs professional behaviour. Based on self-reported questionnaires, this study shows that the GPs after a course in motivational interviewing seemed to change their professional behaviour in daily practice using motivational interviewing compared with the control group. GPs evaluated motivational interviewing to be more effective than 'traditional advice giving'. Furthermore, GPs stated that the method was not more time consuming than 'traditional advice giving'.

BACKGROUND: Motivational Interviewing is a well-known, scientifically tested method of counselling clients developed by Miller and Rollnick and viewed as a useful intervention strategy in the treatment of lifestyle problems and disease. AIM: To evaluate the effectiveness of motivational interviewing in different areas of disease and to identify factors shaping outcomes. DESIGN OF STUDY: A systematic review and meta-analysis of randomised controlled trials using motivational interviewing as the intervention. METHOD: After selection criteria a systematic literature search in 16 databases produced 72 randomised controlled trials the first of which was published in 1991. A quality assessment was made with a validated scale. A meta-analysis was performed as a generic inverse variance meta-analysis. RESULTS: Meta-analysis showed a significant effect (95% confidence interval) for motivational interviewing for combined effect estimates for body mass index, total blood cholesterol, systolic blood pressure, blood alcohol concentration and standard ethanol content, while combined effect estimates for cigarettes per day and for HbA(1c) were not significant. Motivational interviewing had a significant and clinically relevant effect in approximately three out of four studies, with an equal effect on physiological (72%) and psychological (75%) diseases. Psychologists and physicians obtained an effect in approximately 80% of the studies, while other healthcare providers obtained an effect in 46% of the studies. When using motivational interviewing in brief encounters of 15 minutes, 64% of the studies showed an effect. More than one encounter with the patient ensures the effectiveness of motivational interviewing. CONCLUSION: Motivational interviewing in a scientific setting outperforms traditional advice giving in the treatment of a broad range of behavioural problems and diseases. Large-scale studies are now needed to prove that motivational interviewing can be implemented into daily clinical work in primary and secondary health care.
OBJECTIVE: To develop a simple self-administered questionnaire identifying individuals with undiagnosed diabetes with a sensitivity of 75% and minimizing the high-risk group needing subsequent testing. RESEARCH DESIGN AND METHODS: A population-based sample (Inter99 study) of 6,784 individuals aged 30-60 years completed a questionnaire on diabetes-related symptoms and risk factors. The participants underwent an oral glucose tolerance test. The risk score was derived from the first half and validated on the second half of the study population. External validation was performed based on the Danish Anglo-Danish-Dutch Study of Intensive Treatment in People with Screen Detected Diabetes in Primary Care (ADDITION) pilot study. The risk score was developed by stepwise backward multiple logistic regression. RESULTS: The final risk score included age, sex, BMI, known hypertension, physical activity at leisure time, and family history of diabetes, items independently and significantly (P<0.05) associated with the presence of previously undiagnosed diabetes. The area under the receiver operating curve was 0.804 (95% CI 0.765-0.838) for the first half of the Inter99 population, 0.761 (0.720-0.803) for the second half of the Inter99 population, and 0.803 (0.721-0.876) for the ADDITION pilot study. The sensitivity, specificity, and percentage that needed subsequent testing were 76, 72, and 29%, respectively. The false-negative individuals in the risk score had a lower absolute risk of ischemic heart disease compared with the true-positive individuals (11.3 vs. 20.4%; P<0.0001). CONCLUSIONS: We developed a questionnaire to be used in a stepwise screening strategy for type 2 diabetes, decreasing the numbers of subsequent tests and thereby possibly minimizing the economical and personal costs of the screening strategy.
OBJECTIVES: This study aims to describe the use of routine screening for diabetic eye complications in a large population based cohort of type 2 diabetic patients in the County of Vejle, Denmark. Furthermore, it aims to identify characteristics of patients and general practitioners related to the frequency of eye examinations. METHODS: The type 2 diabetic population alive and resident in the County of Vejle on 1st January 1997. Data concerning eye examinations were collected from public data files for the period of January 1993 to December 1997. RESULTS: In a population of 4438 type 2 diabetic patients, 46% had had one annual eye examination in 1997 and 26% had not had a single eye examination within the last five years. Patient characteristics related to an eye examination included: treatment with insulin or oral hypoglycaemic agents, females and long duration of diabetes. The number of diabetic patients who had had an eye examination varied substantially between the general practices. The characteristics of general practitioners were not related to this variation. CONCLUSIONS: The results of this study indicate a great need for quality improvement of ophthalmologic service in diabetes care. To achieve this improvement, more focus should be given to cooperation between the general practitioners and the ophthalmologists.
