A study of the impact of cigarette advertising on adolescent susceptibility to smoking among 5th-, 8th-, and 12th-grade students in Hempstead and Hitchcock Independent School Districts

This study assessed the impact of cigarette advertising on adolescent susceptibility to smoking in the Hempstead and Hitchcock Independent School Districts. A convenience sample of 217 youths, 10-19 years of age was recruited in the study. Students completed both a paper-and-pencil and a computer-aided questionnaire in April 1996. Adolescents were defined as susceptible to smoking if they could not definitely rule out the possibility of future smoking. For the analysis, an index was devised: a 5-point index of an individual's receptivity to cigarette advertising. The index is determined by the number of positive responses to five survey items (recognizing cigarette brand logos, recognizing cigarette advertisement's pictures, recognizing cigarette brand slogans, evaluating adolescent attitudes toward cigarette advertising, and the degree to which adolescents were exposed to cigarette advertisements). Using logistic regression, we assessed the independent importance of the index in predicting susceptibility to smoking and ever smoking after adjusting for sociodemographic variables, perceived school performance and family composition. Of students surveyed, 54.4% of students appeared to have started the smoking uptake process as measured by susceptibility to smoking. Camel was recognized by the majority of students (88%), followed by Marlboro (41.5%) and Newport (40.1%). The pattern for recognition of the cigarette advertisements was the same as the pattern of market for cigarette. Advertisement featuring the cartoon character Joe Camel was significantly more appealing to adolescents than were advertisements with human models, with animal models, and with text only (p $<$ 0.001). Text only advertisement was significantly less appealing than other types of advertisements. The cigarette advertisement with White models (Marlboro) had significantly higher appeal to White students than to African-American students (p $<$ 0.001). The cigarette advertisement featuring African-American models (Virginia Slims) was significantly more appealing to African-American students than other ethnic groups (p $<$ 0.001). Receptivity to cigarette advertising was to be an important concurrent predictor of past smoking experience and intention to smoke in the future. Adolescents who scored in the fourth quartile of the Index of Receptivity to Cigarette Advertising were 7.54 (95% confidence interval (CI) = 1.92-29.56) times as likely to be susceptible to smoking, and were 4.56 (95% CI = 1.55-13.38) times as likely to have tried smoking, as those who scored in the first quartile of the Index. The findings confirmed the hypothesis that cigarette advertising may be a strong current influence in encouraging adolescents to initiate the smoking uptake process than sociodemographic variables, perceived school performance and family composition. ^

Taxonomy of nursing clinical credibility as described by nurses and physicians

Introduction: Nursing clinical credibility, a complex, abstract concept is rarely mentioned in the clinical setting, but is implicitly understood by nurses and physicians. The concept has neither been defined nor explored, despite its repeated use in literature. A review of the extant literature formed the basis for a concept analysis of nursing clinical credibility, which is currently under review for publication. ^ Methods: Using taxonomic analysis, findings of a descriptive qualitative research study in which registered nurses and physicians identified attributes of nursing clinical credibility as it applied to nurses in direct care roles in a hospital setting, formed the basis for development of taxonomies of nursing clinical credibility. A secondary review of literature was undertaken to verify congruence of the taxonomic domains with the work of previous researchers who studied credibility and source credibility. ^ Results: Three taxonomies of nursing clinical credibility emerged from the taxonomic analysis. Using an inductive approach, two separate taxonomies of nursing clinical credibility emerged; one was developed from the descriptions of nursing clinical credibility by registered nurses, and the other from physicians' descriptions of nursing clinical credibility. A third and final taxonomy reflects commonalities within both taxonomies. Three domains were consistent for both nurses and physicians: trustworthiness, expertise, and caring. The two disciplines differed in categories and emphases within the domains; however, both disciplines focused on the attributes of trustworthiness and caring, although physicians and nurses differed on components of expertise. ^ Discussion: Findings from this study of nursing clinical credibility concur with the work of previous researchers who identified trustworthiness and expertise as attributes of credibility and source credibility. Findings suggest however, that trustworthiness and expertise alone are not sufficient attributes of nursing clinical credibility. Caring emerged as an essential domain of nursing clinical credibility according to both nurses and physicians. ^ Products: Products of this research include a concept analysis, two discipline-specific taxonomies of nursing clinical credibility, a third final taxonomy, and a monograph that describes the development of the final taxonomy of nursing clinical credibility. ^
