Psychometric properties of the Autonomy over Tobacco Scale in German.

BACKGROUND/AIMS: We investigated the psychometric properties of a German translation of the 12-item Autonomy over Tobacco Scale (AUTOS) among 1,195 eighth-grade students. METHODS: Data for this study were collected as part of the fourth wave of data collection of the Smokefree Class Competition intervention in the Saxony-Anhalt region of Germany. Students from the control arm of the Smokefree Class Competition study who indicated that they had ever smoked 'at least a few puffs' on a cigarette were classified as ever-smokers. They self-completed questionnaires distributed by teachers. RESULTS: AUTOS scores ranged from 0 to 36 with a distribution highly skewed toward lower-response categories. Inter-item correlations ranged from 0.65 to 0.89 (mean = 0.79, SD = 0.06). Composite reliability for the AUTOS was high (Ω = 0.96) and 3 lower-order factors were also reliable (withdrawal: 0.89, psychological dependence: 0.91, cue-induced cravings: 0.87). Concurrent validity was supported by strong relationships between the AUTOS and both lifetime cigarette consumption and current smoking frequency. Youths were 18 times more likely to be current smokers (95% CI = 11.9-27.2, p < 0.001) if they endorsed any AUTOS item. CONCLUSION: The German AUTOS is reliable and valid, and the results are consistent with the English AUTOS for use with adolescents.

Short term patterns of early smoking acquisition.

OBJECTIVE: To describe short term patterns of smoking acquisition exhibited by adolescent smokers. DESIGN: Interview records from the prospective development and assessment of nicotine dependence in youth study were examined retrospectively. Interviews were conducted three times per year over 30 months. SUBJECTS: 164 students in grades 7-9 (ages 12-15 years, 86 girls, 78 boys) who had used cigarettes at least twice. MAIN OUTCOME MEASURES: A continuous timeline of smoking activity, beginning with the subject's first use of tobacco and continuing through follow up, was translated into six patterns--abstinent, sporadic, occasional, daily, escalating, and intermittent. Outcome measures were the proportion of subjects starting/ending in each pattern, and the number of transitions per subject between patterns. RESULTS: There was a general but discontinuous progression from infrequent to more frequent use, with many interspersed periods of not smoking. Escalation to daily smoking was common after the development of dependence symptoms, but was rare among those who did not have symptoms. After the appearance of symptoms, both transitions to heavier daily smoking and attempts at cessation increased. CONCLUSIONS: Movement to heavier, more frequent smoking is generally unidirectional, although many youths attempt to quit one or more times. The appearance of any symptom of dependence altered the subsequent pattern of smoking behaviour. Future investigators might consider using more frequent data points and a continuous timeline to track smoking behaviour.

Sex differences in peer responsiveness to suicide ideation.

Two surveys assessing attitudes toward and beliefs about suicide were conducted with undergraduates. There were 473 participants in Survey I and 692 participants in Survey II. Sex differences were found in participants' receptivity to suicidal individuals, beliefs about the behavior of suicidal peers, attitudes concerning the worth of suicidal people, incidence of adolescent suicide, and morality of suicide. There was no sex difference in participants' own frequency or seriousness of suicide ideation or suicide attempts. Results are discussed in terms of hypotheses concerning traditional socialization of males and females, resulting in sex-role differentiation that may influence attitudes toward and beliefs about suicide.
