Abstract
Introduction Guilt appeals are widely used as a persuasive approach in various areas of practice. However, the strength and direction of the persuasive effects of guilt appeals are mixed, which could be influenced by theoretical and methodological factors. Method The present study is a comprehensive meta-analysis of 26 studies using a random-effects model to assess the persuasive effects of guilt appeals. In total, 127 effect sizes from seven types of persuasive outcomes (i.e., guilt, attitude, behavior, behavioral intention, non-guilt emotions, motivation, and cognition) were calculated based on 7,512 participants. Results The analysis showed a small effect size of guilt appeals [g = 0.19, 95% CI (0.10, 0.28)]. The effect of guilt appeals was moderated by the theoretical factors related to appraisal and coping of guilt arousal, including attributed responsibility, controllability and stability of the causal factors, the proximity of perceiver-victim relationship, recommendation of reparative behaviors, and different outcome types. The effect was also associated with methods used in different studies. Discussion Overall, the findings demonstrated the persuasive effects of guilt appeals, but theoretical and methodological factors should be considered in the design and testing of guilt appeals. We also discussed the practical implications of the findings.

Entertainment-education to reduce internalized stigma, increase intimate partner status disclosure intentions, and increase antiretroviral medical adherence intentions: A randomized controlled trial targeting black women living with HIV in the Southern U.S. Soc Sci Med 2023; 327:115945.

Abstract
BACKGROUND Black women in the Southern U.S. account for 67% of all new HIV diagnoses across women of all races and ethnicities. In comparison to women of other racial and ethnic identities, Black women disproportionately experience internalized stigma, lower levels of disclosure self-efficacy, and lower rates of medical adherence. The disclosure processes model hypothesizes that persons living with HIV can be disclosure avoidance oriented or disclosure approach oriented. Disclosure avoidance is facilitated by various forms of stigma and negative outcome expectations. While disclosure approach orientation is facilitated by factors such as positive disclosure attitudes and disclosure self-efficacy. Despite the important role of disclosure in ending the HIV epidemic, extant interventions are limited. Recent research suggests entertainment-education (EE) may be an effective intervention for HIV status disclosure. Entertainment-education is a persuasive strategy that consists of intentionally embedding health and social messages into entertaining content. METHODS The present study evaluated the comparative efficacy of the 90 DAYS film for improving internalized HIV stigma, disclosure beliefs, positive disclosure attitudes, disclosure self-efficacy, HIV disclosure intentions, and medical adherence intentions. A randomized controlled trial was employed consisting of 130 Black women living with HIV in the Southern U.S. Participants were recruited primarily via a Qualtrics panel and randomly assigned to either view the 90 DAYS film or a standard of care brochure. RESULTS Results indicated the EE condition significantly outperformed the brochure condition on the following outcomes: disclosure beliefs (p = .046), positive disclosure attitudes (p = .008), disclosure self-efficacy (p = .007), and intentions to disclose to an intimate partner (p = .038). Statistically significant differences were not observed for internalized stigma or medical adherence intentions. CONCLUSION Findings suggest that EE is an effective strategy for improving psychosocial influences of disclosure and disclosure intentions. Theoretical and practical implications of this work are discussed.

Abstract
Previous studies suggest that flood-rich and flood-poor periods are present in many flood peak discharge series around the globe. Understanding the occurrence of these periods and their driving mechanisms is important for reliably estimating future flood probabilities. We propose a method for detecting flood-rich and flood-poor periods in peak-over-threshold series based on scan-statistics and combine it with a flood typology in order to attribute the periods to their flood-generating mechanisms. The method is applied to 164 observed flood series in southern Germany from 1930 to 2018. The results reveal significant flood-rich periods of heavy-rainfall floods, especially in the Danube river basin in the most recent decades. These are consistent with trend analyses from the literature. Additionally, significant flood-poor periods of snowmelt-floods in the immediate past were detected, especially for low-elevation catchments in the alpine foreland and the uplands. The occurrence of flood-rich and flood-poor periods is interpreted in terms of increases in the frequency of heavy rainfall in the alpine foreland and decreases of both soil moisture and snow cover in the midlands.

Abstract
Joking is an important communication behavior that helps people cope with colorectal cancer and colonoscopy screening. However, whether joking serves a beneficial or maladaptive function in the context of colorectal cancer screening remains unknown. The lack of a valid scale impedes our understanding of how joking influences colonoscopy uptake. This study aims to develop and validate the Colonoscopy Joking Scale, a scale of joking behaviors in colonoscopy screening. A sample of Mturk participants aged 50-75 (N = 105) who were not compliant with colonoscopy screening recommendations was recruited to rate items for three joking factors and a measure of colonoscopy screening intentions. Two joking factors (i.e., screening-related and sexual connotation) related to colonoscopy screening and one related to general health were identified in the analysis. The psychometric analysis demonstrated strong convergent, predictive, and discriminant validity. The Colonoscopy Joking Scale will be helpful to understand what joking factor is associated with specific barriers to colonoscopy for different patients so that effective educational and interventional programs can be implemented.

Abstract
Based on the theoretical framework of agency effect, this study examined the role of affect in influencing the effects of chatbot versus human brand representatives in the context of health marketing communication about HPV vaccines. We conducted a 2 (perceived agency: chatbot vs. human) × 3 (affect elicitation: embarrassment, anger, neutral) between-subject lab experiment with 142 participants, who were randomly assigned to interact with either a perceived chatbot or a human representative. Key findings from self-reported and behavioral data highlight the complexity of consumer-chatbot communication. Specifically, participants reported lower interaction satisfaction with the chatbot than with the human representative when anger was evoked. However, participants were more likely to disclose concerns of HPV risks and provide more elaborate answers to the perceived human representative when embarrassment was elicited. Overall, the chatbot performed comparably to the human representative in terms of perceived usefulness and influence over participants' compliance intention in all emotional contexts. The findings complement the Computers as Social Actors paradigm and offer strategic guidelines to capitalize on the relative advantages of chatbot versus human representatives.

Abstract
10564 Background: Cutaneous melanoma is a deadly form of skin cancer. Several studies have shown that early melanoma detection is associated with decreased mortality through self-examination and dermatology full-body skin exams. ABCD rule and the ugly duckling sign (UDS) are used to identify melanomas, but little research has explored the comparative efficacy of these approaches. This investigation compares the effectiveness of different mole identification training strategies and explores the effect of real-time feedback on decision-making. Methods: We developed an online melanoma identification game that tests differences between training types and expert feedback on mole identification. This online RCT tests a 4 (training: ABCD, UDS, both, control) X 3 (feedback: standard, motivational, control) factorial design on melanoma identification, skin cancer beliefs (perceived susceptibility and self-efficacy), and skin cancer prevention intentions. Standard feedback included expert evaluations of moles, whereas motivational feedback added statements grounded in fear appeals theory to encourage skin self-examination. An online research panel service was used to recruit 1025 US adults. Participants were randomly assigned to condition, completed a pretest, participated in the game intervention, and completed a posttest. Gameplay incorporates the same mechanics as Tinder (swipe left on benign moles and swipe right on malignant moles). Results: In total, participants reviewed 48 moles, 12 of which were melanomas. We used two-way ANCOVA for the analysis. ABCD training resulted in significantly higher melanoma identification than the control ( p =.011). Every training type resulted in significantly higher self-efficacy than the control ( p =.007). Additionally, there was a significant main effect of feedback on self-efficacy ( p =.001), where both standard and motivational feedback elicited significantly higher levels of self-efficacy than the control condition. Around 88% of participants intend to conduct skin self-exams and wear sunscreen. Conclusions: Our data suggests that “Whack a Mole” is an efficacious tool for melanoma training. ABCD and UDS training with interactive feedback are important to improve accuracy and ability for melanoma identification.

Abstract
Perceived social norms are routinely observed as positive predictors of indoor tanning. Past research has suggested that messaging interventions target normative perceptions to reduce indoor tanning behavior. Despite this call, little empirical research has investigated the utility of taking a social norms approach in behavioral interventions. The present study addresses this gap by conducting a quasi-experiment (N = 206) assessing the effect of an intervention message correcting normative misperceptions on indoor tanning intentions at different levels of tanning frequency. Results suggest that tailored normative intervention messages can successfully reduce tanning intentions among high-frequency tanners, those who scored at the 75th and 90th percentile of tanning frequency (f2 for interaction = .015). These results provide preliminary empirical evidence to support previous theorizing on the efficacy of social norms interventions among high-frequency indoor tanners.

Abstract
AIM To determine the half life (T1/2), time taken to reach maximum plasma concentration (Tmax) and maximum plasma concentration (Cmax) of thalidomide in sheep following I/V, oral and topical treatment with a single dose of thalidomide. METHOD Three groups of 4-6-month-old ram lambs were treated with thalidomide dissolved in dimethylsulphoxide (DMSO). The first group (n=10) was treated I/V with 100 mg thalidomide in 2 mL DMSO; the second group (n=8) received 400 mg thalidomide in 2 mL DMSO orally, and the third group (n=8) had 400 mg thalidomide in 4 mL DMSO applied topically. Plasma samples were collected up to 36 hours after treatment, snap-frozen at -80°C and analysed for concentrations of thalidomide using high performance liquid chromatography. RESULTS Following I/V administration, T1/2 was 5.0 (SEM 0.4) hours, volume of distribution was 3,372.0 (SEM 244.3) mL/kg and clearance was 487.1 (SEM 46.1) mL/hour.kg. Topical application of 400 mg thalidomide did not increase plasma concentrations. Following oral administration, thalidomide bioavailability was 89%, with T1/2, Tmax, and Cmax being 7.2 (SEM 0.8) hours, 3.0 (SEM 0.4) hours and 1,767.3 (SEM 178.1) ng/mL, respectively. CONCLUSION Topical administration using DMSO as a solvent did not increase concentrations of thalidomide in plasma. The mean pharmacokinetic parameters determined following oral treatment with 400 mg of thalidomide were similar to those reported in humans receiving a single 400 mg oral dose (T1/2 7.3 hours; Tmax 4.3 hours and Cmax 2,820 ng/mL). There is potential for thalidomide to be used as a model for the treatment of chronic inflammatory conditions in sheep, such as Johne's disease, where tumour necrosis factor alpha plays a pathogenic role.
