Segmentation of Mexican-Heritage Immigrants: Acculturation Typology and Language Preference in Health Information Seeking

With the fast growing number of Mexican immigrants in the United States, more attention is needed to understand the relationship between acculturation and language preference in health information seeking. Latent class analysis provides one useful approach to understanding the diversity in sample of Mexican immigrants (N = 238). Based on 13 linguistic, psychological and behavioral indicators for acculturation, four discrete subgroups were characterized: (1) Less acculturated, (2) Moderately acculturated, (3) Highly acculturated, (4) Selectively bicultural. A Chi-square test revealed that three sub-groups were significantly different in language preference when seeking health information. Less acculturated and moderately acculturated groups sought health information in Spanish, whereas the highly acculturated group preferred English for health information. Selectively bicultural group preferred bilingual health information. Implications for health campaign strategies using audience segmentation are discussed

A Longitudinal Study of Parental Anti-Substance-Use Socialization for Early Adolescents’ Substance Use Behaviors

The present study examines the role of communication in shaping norms and behaviors with significant personal and societal consequences. Based on primary socialization theory and the general theory of family communication, parental anti-substance-use socialization processes were hypothesized to influence early adolescents’ substance use norms and behaviors. Using longitudinal data (N =1,059), the results revealed that parent-adolescent prevention communication about substance use in the media and parental anti-substance-use injunctive norms were positively associated with early adolescents’ personal anti-substance-use norms, which, in turn, led to decreases in recent alcohol, cigarette, and marijuana use. It was also found that family expressiveness and structural traditionalism positively related to the hypothesized association between parental socialization processes and early adolescents’ norms and behaviors

Media Literacy and Parent–Adolescent Communication About Alcohol in Media: Effects on Adolescent Alcohol Use

[T]he present study examines the effects of adolescent media literacy and parent-adolescent communication about media portrayals of alcohol use on adolescents\u27 lifetime alcohol use. The focus on alcohol is warranted when evaluating a young adolescent population since alcohol is the substance most commonly used and abused by adolescents (NIDA, 2016).https://digitalcommons.chapman.edu/communication_books/1021/thumbnail.jp

Entertainment-Education Videos as a Persuasive Tool in the Substance Use Prevention Intervention keepin\u27 it REAL

Based on social cognitive theory and narrative engagement theory, the current study examined hypothesized indirect effects of engagement with keepin’ it REAL (kiR) curriculum entertainment–education (E–E) videos on youth alcohol use via youth drug offer refusal efficacy. Students in 7th grade (N = 1,464) at 25 public schools in two Midwestern states were randomly assigned to one of the two versions of the kiR curriculum, the kiR urban version and the kiR rural version. Each version had their own set of five culturally-grounded E–E videos depicting communicative skills to refuse drug offers. Differential effects for engagement components were expected depending on the degree of cultural matching. Pre/post surveys were administered at the beginning and the end of 7th grade. Structural equation modeling analysis resulted in partial support for the research hypotheses. Rural youth receiving the urban curriculum who reported higher interest in the E–E videos were more likely to report having higher refusal efficacy, and in turn, less likely to use alcohol. Rural youth receiving the rural curriculum who identified with the E–E video main characters were more likely to report having higher refusal efficacy, and in turn, less likely to use alcohol. Implications for E–E health promotion are discussed

Designed Cultural Adaptation and Delivery Quality in Rural Substance Use Prevention: An Effectiveness Trial for the Keepin’ it REAL Curriculum

This study examined how cultural adaptation and delivery quality of the school-based intervention keepin’ it REAL (kiR) influenced adolescent substance use. The goal of the study was to compare the effectiveness of the multi-cultural, urban (non-adapted) kiR intervention, a re-grounded (adapted) rural version of the kiR intervention and control condition in a new, rural setting. A total of 39 middle schools in rural communities of two states in the USA were randomly assigned to one of three conditions (i.e., control, non-adapted urban kiR, and adapted rural kiR). Data included adolescent self-reported lifetime substance use and observers’ ratings of delivery quality from video recordings of lessons. Ratings of delivery quality were used to create four comparison groups (i.e., low/high delivery quality in non-adapted/urban kiR condition and low/high quality in adapted/rural kiR condition). Controlling for substance use in the 7th grade, findings compared 9th graders’ (N = 2781) lifetime alcohol, cigarette, marijuana, and chewing tobacco use. Mixed model analyses revealed that rural youth receiving the culturally adapted/rural curriculum reported significantly less cigarette use than rural youth in the control condition regardless of delivery quality. In the non-adapted/urban condition, youth receiving high delivery quality delivery reported less marijuana use than those receiving low delivery quality condition. However, substance use outcomes of youth receiving high and low delivery quality in the non-adapted intervention did not differ significantly from those the control group. Findings support the effectiveness of the culturally adapted/rural keepin’ it REAL curriculum for rural youth

Trends of Parent-Adolescent Drug Talk Styles in Early Adolescence

The present study seeks to understand how parents as prevention agents approach substance use prevention messages during the period of early adolescence. Students (N = 410) in a drug prevention trial completed surveys from 7th to 9th grade. Using longitudinal data, a series of latent transition analyses was conducted to identify major trends of parent–adolescent drug talk styles (i.e., never talked, situated direct, ongoing direct, situated indirect, and ongoing indirect) in control and treatment conditions. Findings demonstrate a developmental trend in drug talk styles toward a situated style of talk as youth transitioned from 7th grade to 9th grade. Findings also show that even though the drug prevention trial did not specifically target parental communication, parents in the treatment condition provide more ongoing substance use prevention messages to their adolescent children than do parents in the control condition. The present study discusses relevant developmental issues, potential intervention effects, and future research directions for communication research in substance use prevention

Parent Prevention Communication Profiles and Adolescent Substance Use: A Latent Profile Analysis and Growth Curve Model

This current study identifies distinct parent prevention communication profiles and examines whether youth with different parental communication profiles have varying substance use trajectories over time. Eleven schools in two rural school districts in the Midwestern United States were selected, and 784 students were surveyed at three time points from the beginning of 7th grade to the end of 8th grade. A series of latent profile analyses were performed to identify discrete profiles/subgroups of substance-specific prevention communication (SSPC). The results revealed a 4-profile model of SSPC: Active-Open, Passive-Open, Active-Silent, and Passive-Silent. A growth curve model revealed different rates of lifetime substance use depending on the youth’s SSPC profile. These findings have implications for parenting interventions and tailoring messages for parents to fit specific SSPC profiles

Understanding confidence in the human papillomavirus vaccine in Japan: a web-based survey of mothers, female adolescents, and healthcare professionals.

Vaccine confidence reflects social, individual, and political factors indicating confidence in vaccines and associated health systems. In Japan, the government ceased proactive recommendation of the human papillomavirus (HPV) vaccine in June 2013, only several months after the recommendation had begun. Seven years later, as of October 2020, the suspension persists and vaccine coverage has precipitously declined, resulting in many young women being continually exposed to the risk of preventable HPV-related diseases. Accordingly, understanding stakeholder opinions on HPV vaccination issues is critical for informing strategies to improve HPV vaccine confidence and acceptance. In October 2019, we performed a nationwide, web-based survey of 1646 mothers of HPV-vaccination-eligible girls, 562 female adolescents aged 15-19 years, and 919 healthcare professionals (HCPs) in Japan. This survey captured key elements of vaccine confidence (i.e., importance, effectiveness, and safety of the HPV vaccine), awareness, and the willingness to receive (in HPV-vaccination-eligible girls) or recommend (in HCPs) the HPV vaccine, and the factors responsible for these decisions. HPV vaccine confidence was generally higher among HCPs than among mothers or female adolescents. Nearly half of all stakeholders were neutral regarding their willingness to receive/recommend the HPV vaccine. The seriousness of cervical cancer and the HPV vaccine's effectiveness or safety were important deciding factors for receiving/recommending the HPV vaccine. Besides these factors, sufficient information and free vaccination were crucial. Our results suggest several factors that could help shape public policy and communication strategies to improve HPV vaccine confidence and acceptance in Japan

Differential Effects of Parental “Drug Talk” Styles and Family Communication Environments on Adolescent Substance Use

The current study examines the relationships among adolescent reports of parent–adolescent drug talk styles, family communication environments (e.g., expressiveness, structural traditionalism, and conflict avoidance), and adolescent substance use. ANCOVAs revealed that the 9th grade adolescents (N = 718) engaged in four styles of “drug talks” with parents (e.g., situated direct, ongoing direct, situated indirect, and ongoing indirect style) and these styles differed in their effect on adolescent substance use. Multiple regression analyses showed that expressiveness and structural traditionalism were negatively related to adolescent substance use, whereas conflict avoidance was positively associated with substance use. When controlling for family communication environments and gender, adolescents with an ongoing indirect style reported the lowest use of substance. The findings suggest implications and future directions for theory and practice

Traffic Optimized Content Precaching Scheme Based on Tolerable Delay Time in Content-Centric Vehicular Networks

The development of smart vehicles such as self-driving cars has resulted in an increased demand for content consumption in vehicles. This demand for content, coupled with the improved quality of the content and the expanding resolution of the display, leads to a significant increase in mobile data traffics with larger sizes in content-centric vehicular networks (CCVNs). Since a single RSU cannot fully provide the larger size contents in its communication coverage due to its limited transmission rate, many studies on precaching contents have been actively conducted. By considering only delay-sensitive contents, previous precaching schemes immediately precache contents in the next continuous RSUs on trajectories of vehicles through paying lots of traffics for reducing delays. However, every application content in CCVNs might generally have a tolerable delay time to vehicles according to its characteristics related to service satisfaction. By considering the tolerable delay time, the already stored content on RSUs reached by vehicles within the tolerable delay time can be exploited to download the content without precaching. As a result, precaching of contents can be reduced and thus the traffics can be also reduced. To address this issue, we thus propose a Traffic Optimized Content Precaching (TOCP) scheme based on the tolerable delay time in CCVNs, which minimizes traffics consumed for delay-tolerant contents and decreases delays for delay-sensitive contents. To do this, we first provide a numerical model to judge the precaching necessity by calculating the content provision possibility. Next, we build a Delay-tolerant content Management Module (DMM) for managing the updated information and design new packet formats for reducing the movements of the large-size contents to achieve the optimization purpose of TOCP. Then, we select Optimal Precaching RSUs (OPRs) by solving our optimization problem by using ILP. Last, we provide a process for allowing only OPRs to participate in the content provision. Through simulation results conducted in various environments, we demonstrate that TOCP minimizes the traffic and caching burden while maintaining high reliability in comparison with the previous schemes
