This is the first study of alcohol-related problems among a Latin American indigenous population using the Alcohol Use Disorders Identification Test (AUDIT). A randomly selected community sample consisting of 3% of the adult population of the tribe completed oral interviews (n = 105 adults, completion rate 86%). The majority of both men (98%) and women (53%) had drunk alcohol at some time in their lives, with 94 and 26% respectively having consumed alcohol within the past 12 months. Using a cut-off score of 8 for the AUDIT, 86.5% of all men and 7.5% of all women were found to be problem drinkers. Focus group discussions revealed that traditional patterns of binge drinking of corn liquor had gradually been replaced by consumption of commercial beer and rum at more frequent intervals and with more negative social consequences. This male population demonstrates one of the highest prevalence rates for problem drinking reported in the world literature. Both the magnitude of problems detected and participants' concerns about them suggest that broad-scale interventions are warranted at the community level.

Studies of alcohol use often depend on self-reported alcohol intake measured by quantity/frequency questionnaires. Previous research has shown that alcohol consumption may be underestimated by this type of retrospective questionnaire. The primary aim of this study was to compare the accuracy of an Alcohol Use Questionnaire (AUQ) with a 4-week diary account, A further aim was to explore patterns of drinking in young social drinkers, with particular attention to binge drinking, which has been suggested as a factor in increasing the risk of alcohol dependency. University students completed the AUQ in the laboratory. They were then asked to keep a record of their alcohol, nicotine and caffeine consumption. over a 4-week period (diary). The questionnaire and the diaries were compared on factors of alcohol intake (units per week) and patterns of drinking behaviour (speed of drinking, number of times being drunk and percentage of times getting drunk when drinking). The two measures (AUQ and diary) were highly correlated on alcohol consumption and the other questions relating to drinking behaviour. However, differences were found between the two measures on alcohol intake, speed of drinking (drinks per hour) and number of times being drunk. Alcohol consumption was underestimated by similar to12% on the questionnaire, and, when the accuracy of estimation of drinking habits was examined, it was found that high drinkers tended to underestimate their drinking behaviour, whereas lower drinkers tended to overestimate. The results suggest that the AUQ can be used with a reasonable degree of confidence, bearing in mind the tendency for high drinkers to underestimate consumption and drinking behaviour. Relationships between 'binge scores', beverage specificity and alcohol consumption support the idea that the criteria for binge drinkers should be based on patterns of drinking rather than alcohol consumption.

We examined patterns of care for 1246 adults treated for bipolar disorder in a large health maintenance organization. Computerized pharmacy and visit data were used to identify patients treated for bipolar disorder. Automated medical records for the following year were used to assess continuity and nosing of treatment with mood stabilizers, laboratory monitoring for adverse effects and therapeutic serum levels, and frequency of follow-up visits. Of our 1246 subjects 83% filled a mood stabilizer prescription during the 1-year study period, and doses were within recommended ranges 80% of the rime. Over 75% of the patients on mood stabilizers had at least one apparent interruption in medication use. Approximately half of the long-term users of mood stabilizers had at least one 7-month period without a recorded blood level and approximately half had a similar period without monitoring for adverse medication effects. Of the 116 subjects discharged from a psychiatric hospitalization 58% had a visit with a psychiatrist or a psychiatric nurse practitioner within 30 days. Of those discontinuing mood stabilizer treatment 68% made a mental health visit within 90 days. Our findings demonstrate the feasibility of using administrative data systems for population-based qualify of care assessment and suggest opportunities for improving the care of bipolar patients.

The Indianapolis-Ibadan Dementia Project compares the rates of dementia at two sites, one in the U.S.A. and one in Nigeria. This paper concentrates on the data management issues in this longitudinal cross-cultural study. Approximately 2500 elderly people were recruited at each site, and continue to be re-assessed every two years. All the data are collected on paper and then entered into a FoxPro relational database. Most of the data management, including data cleaning, is done in Indianapolis. The design of the data collection forms is particularly important in a cross-cultural study, with the questions and the coding of responses clear and simple. Since Nigeria and the U.S.A. have different levels of technological development, the computer hardware and software were chosen to be suitable for use at either site. Exchange visits have been needed to address data management issues and resolve unexpected problems. The data management on cross-cultural studies can be handled successfully, given careful planning.

Longitudinal studies of cognitive function in Alzheimer's disease (AD) patients are powerful tools to better understand the biology and natural history of the disease, but the attributes of the studies that make them valuable also pose special challenges to analysts. A fundamental problem is the accurate measure of time at which cognitive decline begins. Investigators typically use the date of AD diagnosis or the date of enrolment in an AD study. If the rate of cognitive decline is non-linear, variables associated with the time of diagnosis or enrolment might artificially be associated with the rate of decline. Unlike the mixed effects models typically used to analyse cognitive decline, summary measure analyses do not directly compare the rate of decline with time since decline began, and, therefore, are less sensitive to biased measures of time of decline. We simulated trajectories of cognitive decline using the multivariate normal random effect model and tested the ability of the two analytic techniques to discriminate between true and spurious associations. Our analyses suggest summary measure models are less likely to detect spurious associations generated by biased measures of time at which decline begins, and more likely to detect true associations concealed by biased time measurement.

A summary of methods to decrease attrition in longitudinal school-based studies conducted with adolescents beginning junior high schools or middle schools is presented. These include collection of contact information about students, additional days to collect data from absentee students, data collection in new high schools once students graduate from junior high schools or middle schools, sending questionnaires by mail, and conducting telephone or home interviews.
