This research expands the user/nonuser dichotomy commonly used in research on marijuana. By conceptualizing nonusers as homogeneous, vital nuances in susceptibility to risk and protective factors may be overlooked. Research operations tested the predictive validity of a brief measure that divided nonusers into resolute and vulnerable subcategories; determined whether variables that distinguished nonusers and users were more informative when a tripartite classification was used; and with an eye on future prevention, examined variables on which resolute nonusers were similar to vulnerable nonusers or users, and on which they differed from both. A nationally representative sample of respondents (N = 2,111; ages 12-16 years) from the National Survey of Parents and Youth was used in this secondary analysis. Panel data gathered yearly over four rounds included information on intentions and use of marijuana and other illicit substances, along with social, demographic, intrapersonal, and parental variables. The three groups differed significantly on associates' marijuana use, participants' approval of others' use, and cigarette and alcohol use. Resolute nonusers differed from vulnerable nonusers and users alike on religiosity, delinquency (self and friends'), refusal strength, sensation seeking, parental monitoring and warmth, and adult supervision. Results support the utility of distinguishing vulnerable from resolute nonusers, counsel against considering nonusers as a homogeneous group, and provide insight into variables that might prove useful in future prevention efforts. 相似文献
Although peer influence typically has been associated with the promotion of alcohol and drug use among adolescents, a minority of writers has argued that appropriate kinds of peer interactions may work favorably to reduce usage. This empirical study considered two kinds of peer affiliations--formal and informal group participation--and their relationships with use of alcohol and drugs. Findings suggest that ad hoc, informal group participation is related to increased substance use, whereas formal group membership is related to reduced substance use. This article reviews these findings in the context of two theoretical explanations. 相似文献
With an eye toward future primary prevention efforts, this study explores perceptions of inhalant utility among young adolescents in the United States. The study makes use of data gathered via nine focus groups conducted in Tucson, Arizona in 2004 (N = 47, mean age = 13.2 years). Three main themes emerged concerning the perceived utility of inhalant use: (1) Inhalant use as a means of mental escape, (2) Inhalant use as a social tool, and (3) Inhalant use as a parental relations tool. Additionally, participants discussed an interaction hypothesis regarding inhalant use and popularity. Implications for future research are suggested and limitations described. 相似文献
People with depression are likely to process information with a negative bias when confronted with self-relevant information. Accordingly, we feared exposing depressed people to a public service announcement (PSA) addressing the stigma of depression would possibly boomerang and result in less intention to seek help and in increased self-stigma. College students (N?=?271; Mage?=?22.51, SD?=?4.71; 63.1% female; 37.3% White, 31.9% Hispanic, 12.9% Asian, 6.8% multiethnic, 3.4% Black, 7.6% other) were randomly assigned to receive a print ad focused on depression or a nonrelevant comparison ad. A paper-and-pencil survey consisting of the Beck Depression Inventory–II, Self-Stigma of Seeking Help scale, help-seeking intentions, and demographics followed. Regression analysis indicated that viewing a depression ad caused people with greater depressive symptoms to experience greater levels of self-stigma than depressed people exposed to a nonrelevant comparison ad. Bootstrap mediation analysis showed that for individuals who viewed a depression PSA, self-stigma mediated the relationship between depressive symptoms and professional help-seeking intentions. While this current study offers no direct evidence in regard to the utility of current and past depression campaigns, results indicate a definite need for caution when developing materials targeting people with depression to seek help. 相似文献
This research examines the impact of a Spanish language mass media campaign on living organ donation attitudes and behavioral intentions among Spanish dominant Hispanics in Tucson, Arizona. Impact was assessed via a pretest/posttest control group quasiexperimental design with Tucson, Arizona, as the intervention community and Phoenix, Arizona, as the control. Preintervention focus groups provided qualitative data to guide intervention development, while telephone surveys in both communities provided quantitative data to assess campaign impact. Analyses reveal pretest/posttest differences in the intervention community such that posttest intentions regarding living organ donation behaviors increased from pretest. No such differences were observed in the control community. Subsequent analyses revealed differences between respondents in the intervention community exposed to the campaign vs. those in the same community not exposed to the campaign. Exposed respondents reported more positive living organ donation behavioral intentions than nonexposed respondents. Implications for research and practice are discussed. 相似文献
Culturally, people tend to abstain from alcohol intake during the weekdays and wait to consume in greater frequency and quantity during the weekends. The current research sought to empirically justify the days representing weekday versus weekend alcohol consumption. In study 1 (N?=?419), item response theory was applied to a two-parameter (difficulty and discrimination) model that evaluated the days of drinking (frequency) during the typical 7-day week. Item characteristic curves were most similar for Monday, Tuesday, and Wednesday (prototypical weekday) and for Friday and Saturday (prototypical weekend). Thursday and Sunday, however, exhibited item characteristics that bordered the properties of weekday and weekend consumption. In study 2 (N?=?403), confirmatory factor analysis was applied to test six hypothesized measurement structures representing drinks per day (quantity) during the typical week. The measurement model producing the strongest fit indices was a correlated two-factor structure involving separate weekday and weekend factors that permitted Thursday and Sunday to double load on both dimensions. The proper conceptualization and accurate measurement of the days demarcating the normative boundaries of “dry” weekdays and “wet” weekends are imperative to inform research and prevention efforts targeting temporal alcohol intake patterns. 相似文献
Despite research indicating that effective parenting plays an important protective role in adolescent risk behaviors, few
studies have applied theory to examine this link with marijuana use, especially with national data. In the current study (N = 2,141), we hypothesized that parental knowledge (of adolescent activities and whereabouts) and parental warmth are antecedents
of adolescents’ marijuana beliefs—attitudes, subjective norms, and perceived behavioral control—as posited by the Theory of
Planned Behavior (TPB; Ajzen 1991). These three types of beliefs were hypothesized to predict marijuana intention, which in turn was hypothesized to predict
marijuana consumption. Results of confirmatory factor analyses corroborated the psychometric properties of the two-factor
parenting structure as well as the five-factor structure of the TPB. Further, the proposed integrative predictive framework,
estimated with a latent structural equation model, was largely supported. Parental knowledge inversely predicted pro-marijuana
attitudes, subjective norms, and perceived behavioral control; parental warmth inversely predicted pro-marijuana attitudes
and subjective norms, ps < .001. Marijuana intention (p < .001), but not perceived behavioral control, predicted marijuana use 1 year later. In households with high parental knowledge,
parental warmth also was perceived to be high (r = .54, p < .001). Owing to the analysis of nationally representative data, results are generalizable to the United States population
of adolescents 12–18 years of age. 相似文献
Adolescent alcohol use has been linked with a multitude of problems and a trajectory predictive of problematic use in adulthood. Thus, targeting factors that enhance early prevention efforts is vital. The current study highlights variables that mitigate or predict alcohol use and heavy episodic drinking. Using Monitoring the Future (MTF) data, multiple path analytic models revealed links between parental involvement and alcohol abstinence and initiation. Parental involvement predicted enhanced self-esteem and less self-derogation and was negatively associated with peer alcohol norms for each MTF grade sampled, with stronger associations for 8th and 10th graders than 12th graders. For younger groups, self-esteem predicted increased perceptions of alcohol risk and reduced drinking. Self-derogation was associated with peers’ pro-alcohol norms, which was linked to lower risk perceptions, lower personal disapproval of use, and increased drinking. Peer influence had a stronger association with consumption for 8th and 10th graders, whereas 12th graders’ drinking was related to personal factors of alcohol risk perception and disapproval. In all grades, general alcohol use had a strong connection to heavy episodic drinking within the past 2 weeks. Across-grade variations in association of parent, peer, and personal factors suggest the desirability of tailored interventions focused on specific factors for each grade level, with the overall goal of attenuating adolescent alcohol use. 相似文献
Adolescent depression is associated with many negative outcomes, including elevated marijuana use. Although parental influences on adolescent depressive symptoms and marijuana use have been examined independently, their interrelation remains understudied. The current research investigates the hypothesis that lower levels of parental monitoring and warmth are inversely associated with adolescent depressive symptoms and marijuana use. A path analytic approach (N = 12,115) on data from a representative US sample indicated depressive symptoms had an indirect effect on the relationship between parental warmth (p < .001), monitoring (p = .013), and adolescent marijuana use. Exploring relationships grouped by respondents’ age (12–14 and 15–17 years, respectively) revealed minor differences. Depressive symptoms had significant indirect effects on parental warmth and marijuana use (both p < .001) and on parental monitoring and marijuana use (both p < .05). Parental influences appear to play an important role in marijuana use among adolescents with depressive symptoms.
