Differential Performance of Social Communication Questionnaire Items in African American/Black vs. White Children.

Screening for autism spectrum disorder (ASD) is an essential early step in the identification process and inaccurate screening may lead to significant delays in the onset of treatment. Past research has highlighted discrepancies in the performance of ASD screening tools such as the Social Communication Questionnaire (SCQ) among certain racial and ethnic groups. The current study explored the functioning of the SCQ among African American/Black and White respondents based on item level performance on the measure. Differential Item Functioning (DIF) analyses showed that 16 (41%) items of the SCQ functioned differently for African American/Black respondents when compared to White respondents. Implications, such as the potential for delayed diagnosis and treatment, and the influence on downstream outcomes, are discussed.

A comparison of costs of two forms of educator professional development in Wyoming: Traditional conference vs. project ECHO.

Educator professional development (PD) is essential for improving student outcomes (Guskey, 1986, 2002). However, logistical challenges with traditional in-person conferences can detract from the reach of educator PD (Corcoran, 1995; Johnston, 1994; Shaffer & McNinch, 1997; Stephens, 1991). Project ECHO is a model of PD that utilizes videoconferencing technology to provide training to educators in rural or underserved areas through didactic presentations and case-based learning (Arora et al., 2007; Root-Elledge et al., 2018) while eliminating some of the challenges faced by traditional conferences. However, cost comparisons between ECHO and various forms of PD have not previously been considered. The current study utilizes an in-depth cost comparison to examine PD delivered by ECHO relative to traditional conferences. Findings suggest that ECHO is more affordable for funders and attendees overall. ECHO for Education may, therefore, be a useful tool in delivering PD to educators in rural and remote communities.

Visual Juxtapositions as Exemplars in Messages Promoting Healthy Dietary Behavior.

While health communicators often study strategic health messages, investigations of how visual message elements complement or inhibit persuasive efforts are sparse in the literature. Visual juxtapositions, which refer to one visual presentation featuring two images placed next to each other, are one such visual element. In the context of improving public communication efforts related to promoting healthy dietary choices, we use visual persuasion theory and exemplification theory to test whether different visual juxtapositions influence message recipients' expectations to share message content and reduce their consumption of unhealthy products (i.e., sugary drinks and salty foods). We carried out two studies, each a two-wave, longitudinal randomized experiment, to test for direct effects and assess the potential for indirect or delayed associations of visual persuasion appeals using visual juxtapositions. We consistently observed that a similarity visual juxtaposition evoked higher levels of surprise and expectations to share message content than a comparison juxtaposition or control condition immediately following message exposure; however, visual juxtapositions had no direct effects on unhealthy consumption expectations immediately following exposure or one-week following exposure. Levels of surprise were associated with both intended outcomes in the short-term (increased message sharing expectations) and unintended outcomes in the longer-term (increased consumption expectations). Overall, the study offers insights into the effects and associations of visual juxtapositions on message processing and persuasion outcomes, as well as raises questions about how to apply visual persuasion concepts and improve theorizing related to visual persuasion in health communication contexts.

Loving the Group That Denies You First: Social Identity Effects of Ostracism Before Inclusion.

Ostracism is an aversive situation that occurs frequently in everyday life; however, few empirical studies have investigated multiple experiences of inclusion or ostracism from the same group. The prior work in this area has also not evaluated the influence of subsequent inclusion and ostracism on identification with the group, perceptions of the group, or group member behaviors. Across three experiments, the current study investigated the impact of subsequent inclusion and ostracism on an individual's fundamental needs, identification with the group, perceptions of the group, and risk taking to benefit the group. It was hypothesized that participants who were ostracized and then included would show significant increases in group identification, positive group perceptions, and risk taking to benefit the group. Support for these hypotheses was found. Results are discussed regarding the impact of subsequent experiences of ostracism and inclusion on the individual and his or her relationship with the group.

Gambling and the Reasoned Action Model: Predicting Past Behavior, Intentions, and Future Behavior.

Gambling is a serious concern for society because it is highly addictive and is associated with a myriad of negative outcomes. The current study applied the Reasoned Action Model (RAM) to understand and predict gambling intentions and behavior. Although prior studies have taken a reasoned action approach to understand gambling, no prior study has fully applied the RAM or used the RAM to predict future gambling. Across two studies the RAM was used to predict intentions to gamble, past gambling behavior, and future gambling behavior. In study 1 the model significantly predicted intentions and past behavior in both a college student and Amazon Mechanical Turk sample. In study 2 the model predicted future gambling behavior, measured 2 weeks after initial measurement of the RAM constructs. This study stands as the first to show the utility of the RAM in predicting future gambling behavior. Across both studies, attitudes and perceived normative pressure were the strongest predictors of intentions to gamble. These findings provide increased understanding of gambling and inform the development of gambling interventions based on the RAM.
