Community data concerning drug and alcohol usage patterns was assessed via a unique "personal delivery" system. The system, which can be used for collecting other community data produced a return rate of 45% and was very economical. This system largely overcomes the main drawback of the mailed questionnaire (low return rate) by (1) having questionnaire distributors establish rapport with the subject, (2) personally convincing the subject of the importance of the study, (3) getting a "foot in the door" with a personal commitment from the subject, and (4) giving the subject two different ways to return the questionnaire. Although the stress is on a data collection system, several brief summary tables are included to give an overview of the results that were collected. (Author/BN)
