Do school based anti-smoking campaigns delivered by oral health therapists work?

BACKGROUND: The dental profession has a pivotal role in cancer prevention. In Queensland, oral health therapists (OHTs) are in a unique position to provide quality smoking cessation programmes and intervention strategies to young adolescents through the school based oral health services they provide. METHODS: This study undertook a smoking cessation and prevention programme targeted to female high school students in a dental setting. An oral health therapist delivered an anti-smoking message and educated adolescents of the health-risk effects of smoking. RESULTS: A total of 1217 female students were recruited with 621 (51%) in the intervention group and 596 (49%) in the control group. There was a significant improvement in the knowledge of both systemic and oral health effects of smoking in the intervention group (p < 0.04). The results of the study demonstrated that the dental setting is an effective avenue for educating young individuals on smoking related conditions. CONCLUSIONS: A smoking cessation and prevention programme targeted to female high school students in a dental setting provides a novel means of delivering an anti-smoking message and educating adolescents of the health-risk effects of smoking.

Use of the Booklet Category Test to assess abstract concept formation in schizophrenic disorders.

The relationship of concept formation abilities to the presence or absence of delusions in schizophrenic disorders was investigated. Twenty-six schizophrenic patients and 14 normal individuals were administered a short form of the Booklet Category Test (BCT). Patients were grouped into those with and without delusions. It was hypothesized that the delusional group would perform significantly better on the BCT (obtain lower error scores) than the nondelusional group. Normal and delusional groups obtained significantly lower BCT error scores than the nondelusional group, even when differences in IQ scores were statistically partialled out. The two schizophrenic groups also differed significantly on BCT error scores with the delusional group performing better than the nondelusional group.

Psychometric properties of Russell's short form of the Booklet Category Test.

Russell's short form of the Booklet Category Test was administered to 26 diagnosed schizophrenic patients and 14 normal individuals along with a test of premorbid intelligence. IQ correlated significantly (inversely) with errors and in particular with Subtests 3, 4, and 6. Age related directly to errors, especially for Subtests 3, 4, and 5. The mean Cronbach coefficient alpha was .71, indicating moderate item homogeneity across subtests. In sum, the shortened form appears to be an efficient and effective measure of concept formation among schizophrenic individuals.
