Latent growth modeling allows social behavioral researchers to investigate within-person change and between-person differences in within-person change. Typically, conventional latent growth curve models are applied to continuous variables, where the residuals are assumed to be normally distributed, whereas categorical variables (i.e., binary and ordinal variables), which do not hold to normal distribution assumptions, have been rarely used. This article describes the latent growth curve model wi

Although television medical dramas have been popular for a long time and have delivered health- and medical-related information to audiences, few studies have focused on audience's view. This study explores motives for and consequences of viewing medical dramas from the uses and gratifications (U&G) perspective. A survey identified college students' motives toward medical drama viewing and the relationship of the motives with individuals' health information orientation, audience activity (select

This study examines whether the characteristics of those who share news articles on social media influence the hostile media effect. In an experiment, participants read a news article shared by 1 of 4 Twitter users, 2 (Republican vs. Democrat) × 2 (21 vs. 503,000 followers). Consistent with the hostile media effect, both Republicans and Democrats believed that a news article shared by a Twitter user from an opposing political party was more biased than one shared by a Twitter user from the same

Pinecones from Pinus koraiensis Siebold & Zucc . (Pinaceae), which have historically been treated as an undesired waste by‐product in the processing of seeds, have recently been shown to contain ingredients with potent biological activities, such as polyphenols exhibiting antitumor activity. With this study, we seek to broaden our understanding of antitumor compounds contained in these pinecones beyond just polyphenols. We found that the water extract of P. koraiensis pinecones exhibits sign

This study examines the relative efficacy of citizen science recruitment messages appealing to four motivations that were derived from previous research on motives for participation in citizen-science projects. We report on an experiment (N=36,513) that compared the response to email messages designed to appeal to these four motives for participation. We found that the messages appealing to the possibility of contributing to science and learning about science attracted more attention than did on

The current study examines how a personal health story on a blog can influence individuals' perceived social norms, adopting the notion that social norms are "group identity-based codes of conduct". For that, we tested the effects of story framing and personal experience on perceived similarity, which interacts with social media metrics in forming perceived social norms. In an online experiment, college students (<i>N</i> = 220) were recruited to read a blogger's story in either a gain-frame (th

Abstract Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, Mage (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3

INTRODUCTION: The pervasive use of technology has raised concerns about its association with adolescent mental health, including internalizing symptoms. Existing studies have not always had consistent findings. Longitudinal research with diverse subgroups is needed. METHODS: This study examines the relationship between screen-based sedentary (SBS) behaviors and internalizing symptoms among 370 Hispanic adolescents living in Miami, Florida- United States, who were followed for 2 ½ years and asses

Several theories, including disposition-based theories, depend on moral judgments about narrative characters’ actions to describe how audiences understand characters in media narratives. However, more needs to be known about how moral judgments about characters’ actions are made and affective dispositions toward characters are formed and change as a story unfolds. There is evidence that the intentionality underlying a character’s actions is an important judgment that audiences use to understand

This study tests whether gain- and loss-framed messages about establishing obesity-reducing policies have different persuasive effects on Republicans and Democrats. In a randomized between-subject experiment, participants (N = 384) read a message emphasizing either benefits to a society by establishing policies aimed to reduce obesity (i.e., gain-framed message) or costs to a society that fails to establish those policies (i.e., loss-framed message). Results indicated that Democrats perceived th
