The effects of self-disclosure and gender on a climate scientist's credibility and likability on social media.

To examine whether different types of disclosure made by climate scientists on social media influence perceived source credibility (i.e. competence, integrity, benevolence) and likability, we conducted a 2 (self-disclosure type: personal vs political) × 3 (proportion of posts including a self-disclosure: 20% vs 50% vs 80%) × 2 (gender identity of scientist: male vs female) between-subjects experiment (N = 734). We found that people liked the scientist more for a personal than political disclosure, rated them as being more competent for a political disclosure, and liked a female scientist more than a male scientist. However, scientist's gender did not moderate the effect of disclosure type or the effect of participants' gender. Our results suggest distinct benefits when scientists deliver different types of messages on social media, although disclosure is unlikely to have substantial effects on lay judgments of scientists' credibility.

Preventive Education Outreach on Social Media: The Quest to Enroll Community Members in a Child Sexual Prevention Workshop.

Social media is a frequently used tool in health promotion efforts although less so for the prevention of child sexual abuse (CSA). This is due, in part, to the lack of standardized branding guides for community-based efforts in how to craft messages related to CSA prevention. This study examined the use of Twitter (now "X") as a means of promoting participation in the adult-focused Stewards of Children CSA prevention workshop, prior to and following the implementation of a standardized branding guide. The exposure, reach, and engagement of the top tweets and top media tweets were examined over 24-months pre- and post-implementation of a five-point branding guide. Engagement was descriptively compared to the number of adults who enrolled in the Stewards of Children workshop. As evidenced by the increase in tweet impressions and the number of adults trained, it is likely the implementation of the branding guide was beneficial in promoting participation in the Stewards of Children workshop. Though participation in a program does not inherently suggest behavior change, getting participants to enroll is a crucial first step. The findings emphasize the potential of using social media to ultimately promote behavior change in the field of CSA prevention and beyond.

Pharmacologic and Non-Pharmacologic Treatments for Chronic Pain Used by Patients with Pain, HIV, and Depression.

The objective of this study was to understand pain treatment utilization, perceived efficacy, and differences in utilization by gender, clinic site, chronicity of pain, pain severity, and depression severity among people living with HIV (PLWH), chronic pain, and elevated depression symptoms. Participants included 187 PLWH at three HIV clinics in the U.S. Overall, 85% of participants reported taking a pain medication. One quarter (25%) reported non-pharmacological professional treatments for pain (e.g., massage, physical therapy), 60% reported mind-body treatments, including exercise, meditation, and yoga, and 62% reported other non-pharmacological self-administered treatments (e.g., heat/cold). Most pain treatments were considered "slightly helpful" or "moderately helpful." Non-pharmacological self-administered treatments were more commonly used among women than men and among individuals with constant vs. intermittent pain. Further research is needed to evaluate the efficacy of the preferred analgesic modalities of PLWH.

A Randomized Trial Comparing Brief Advice and Motivational Interviewing for Persons with HIV-HCV Co-infection Who Drink Alcohol.

Alcohol use contributes to the progression of liver disease in HIV-HCV co-infected persons, but alcohol interventions have never addressed low levels of alcohol use in this population. We enrolled 110 persons consuming at least 4 alcoholic drinks weekly in a clinical trial comparing two active 18-month long interventions, delivered every 3 months by phone, brief advice about drinking versus a motivational intervention. Final assessment was at 24 months. MI had larger reductions in alcohol use days than the BA arm at all follow-up assessments. The treatment by time effect was not significant for days of drinking (p = 0.470), mean drinks per day (p = 0.155), or for the continuous FIB-4 index (p = 0.175). Drinking declined in both conditions from baseline, but given the small sample, we do not have sufficient data to make any conclusion that one treatment is superior to the other.Trial Registry Trial registered at clinicaltrials.gov; Clinical Trial NCT02316184.

Seasonality in diurnal locomotory patterns of adult blacklegged ticks (Acari: Ixodidae).

We continuously recorded the activity of adult and nymphal blacklegged ticks, Ixodes scapularis Say, exposed to diurnal light and temperature cycles in a laboratory test chamber by using a digital camera controlled by an intervalometer. Adult ticks collected and tested in the fall exhibited a bimodal pattern of activity, with peaks shortly after lights on and shortly after lights off, and substantial daytime activity. However, adult ticks collected in the winter and early spring exhibited a unimodal pattern of activity, peaking shortly after lights off, and minimal daytime activity. Nymphs, collected and tested in the summer, exhibited only a unimodal pattern of activity, peaking after lights off. Limited data also are presented for adult ticks exposed to only a temperature cycle or to only a light cycle in the spring. Ticks exposed to a temperature cycle exhibited a unimodal pattern of activity, similar to that exhibited by ticks exposed to both light and temperature cycles at the same time of year, whereas those exposed to a light cycle exhibited a bimodal pattern of activity. Although the difference did not quite reach statistical significance, there is a possibility that temperature is a stronger entraining agent for tick diurnal activity than is light, an unusual situation. The change in diurnal activity pattern from fall to spring suggests that ticks are adjusting their strategy for host finding, possibly in relation to remaining stored food supplies or host activity, and may have practical implications for sampling carried out to track tick populations.
