The use of smokeless tobacco products is increasing among teenagers and young adults in the United States. Community health professionals play a vital role in educating the public about these products, and in this regard the dental hygienist is of critical importance. This study evaluated the knowledge and attitudes towards smokeless tobacco among a representative sample of dental hygiene students in the United States. The dental hygiene schools were divided into six geographical regions and a total of 34 schools and 722 students participated. Seniors were found to score significantly higher than non-seniors both in knowledge and attitude. Furthermore, some significant differences in attitude were discovered between regions. In general, students scored poorly on both knowledge and attitude despite reporting having received classroom instruction on smokeless tobacco.

The purpose of this study was to assess the effectiveness of the Denton County Safety Education Program. Subjects were 117 driving-while-intoxicated offenders who completed this alcohol reeducation program between June 1975 to June 1976. Questionnaires were used as evaluative measures. Data were analyzed in three steps: 1) two two-way ANOVAs with one repeated measure; 2) two Pearson product moment correlations; and 3) a Fisher's Z test. Conclusions of the investigation were that (1) both problem and non-problem drinkers benefited from the program; (2) change of attitude was an important factor in reducing recidivism; and (3) the program was successful in meeting its goals as a means of influencing drinking and driving behavior.
