The longitudinal impact of a family-based communication intervention on observational and self-reports of sexual communication

Hadley, Wendy; Lansing, Amy; Barker, David H; Brown, Larry K; Hunter, Heather; Donenberg, Geri; DiClemente, Ralph J
Parents can play a vital role in shaping teenagers' sexual attitudes, behavior, and contraceptive use through communication, however, less is known about how to modify parent-adolescent communication among youth with mental health problems. The impact of a family-based sexual risk prevention intervention on both observational and self-report of parent adolescent sexual communication was examined at 12-months among adolescents with mental health problems. Of the 721 parent- adolescent dyads recruited for the study, 167 videotapes of sexual discussions between parents and adolescent were coded for the family-based intervention and 191 videotapes for the active comparison. Longitudinal analyses examined differences between conditions (family-based vs. comparison) in self-reported and observed parent-adolescent sexual discussions and also examined the impact of gender on intervention response. More parent I-statements, healthier parent Body-Language, and fewer adolescent Negative Vocalizations were detected for family-based intervention participants 12 months after participating in the brief intervention (11 hours of total intervention time) relative to those in the comparison condition. Parents in the family-based intervention also self-reported better sexual communication at 12-months. The current study provides supporting evidence that a relatively brief family-based intervention was successful at addressing parent-adolescent sexual communication among a mental health sample.

Willingness to pay for an Ebola vaccine during the 2014-2016 ebola outbreak in West Africa: Results from a U.S. National sample

Painter, Julia E; von Fricken, Michael E; Viana de O Mesquita, Suyane; DiClemente, Ralph J
The 2014-2016 Ebola virus outbreak in West Africa led to advances in the development of vaccines against Ebola. This study examined factors associated with willingness to pay for an Ebola vaccine among a U.S. national sample during the recent Ebola outbreak. From April 30-May 8, 2015, a national survey was conducted using the GfK Group's KnowlegePanel®. Main outcome measures included willingness to pay at least $1; more than $50; and more than $100 for an Ebola vaccine. Analyses were conducted using weighted multivariable logistic regression. Among participants (N = 1,447), 583 (40.3%) would not pay for an Ebola vaccine; 864 (59.7%) would pay at least $1. Among those willing to pay at least $1: 570 (66.0%) would pay $1-50; 174 (20.1%) would pay $51-100; and 120 (13.9%) would pay more than $100. Willingness to pay at least $1 for an Ebola vaccine was associated with international travel; interest in getting an Ebola vaccine; and beliefs that the U.S. government should spend money to control Ebola and assume worldwide leadership in confronting emerging epidemics. Willingness to pay more than $50 was associated with similar variables. Willingness to pay more than $100 was associated with international travel; interest in getting an Ebola vaccine; information seeking; and beliefs that the U.S. government should assume worldwide leadership in confronting emerging epidemics. International travel and interest in an Ebola vaccine were key predictors of willingness to pay across all price points. Understanding willingness to pay for vaccines against emerging infectious diseases remains critical.

The MEDIA model: An innovative method for digitizing and training community members to facilitate an HIV prevention intervention

Renfro, Tiffaney; Johnson, Erin; Lambert, Danielle N; Wingood, Gina; DiClemente, Ralph J
As human immunodeficiency virus (HIV) continues to disproportionately affect African American women, practitioners remain committed to developing innovative strategies to reduce HIV prevalence. These strategies include training community organizations, such as churches, and utilizing digital media to make intervention dissemination more sustainable. This article describes one such effort to train lay community members within predominantly Black churches in Atlanta, GA, to implement an HIV prevention intervention. Lay educators were trained by translating a face-to-face Training of Facilitators (TOF) to a digital platform using the MEDIA (Motivate-Engage-Digitize-Implement-Assess) model. Formative evaluations, consultation with experts in the digital platform of choice, and the experience of two P4 for Women Master Trainers informed our translation. The model guided the translation process as our research team worked alongside topical experts and a production company to develop storyboards for core curriculum activities, which were later scripted and filmed with mock participants. A user guide, toolkit, and program website were also developed as supplemental materials to accompany the video training. Lessons learned from this study indicate future attempts at digitizing TOFs should keep in mind that digitization can be a time-consuming process, pilot testing in the new format is necessary even for a previously tested intervention, and the structure provided by facilitators in face-to-face training must be embedded into the format of digitized trainings.

A model for rigorously applying the Exploration, Preparation, Implementation, Sustainment (EPIS) framework in the design and measurement of a large scale collaborative multi-site study

BACKGROUND:This paper describes the means by which a United States National Institute on Drug Abuse (NIDA)-funded cooperative, Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS), utilized an established implementation science framework in conducting a multi-site, multi-research center implementation intervention initiative. The initiative aimed to bolster the ability of juvenile justice agencies to address unmet client needs related to substance use while enhancing inter-organizational relationships between juvenile justice and local behavioral health partners. METHODS:The EPIS (Exploration, Preparation, Implementation, Sustainment) framework was selected and utilized as the guiding model from inception through project completion; including the mapping of implementation strategies to EPIS stages, articulation of research questions, and selection, content, and timing of measurement protocols. Among other key developments, the project led to a reconceptualization of its governing implementation science framework into cyclical form as the EPIS Wheel. The EPIS Wheel is more consistent with rapid-cycle testing principles and permits researchers to track both progressive and recursive movement through EPIS. Moreover, because this randomized controlled trial was predicated on a bundled strategy method, JJ-TRIALS was designed to rigorously test progress through the EPIS stages as promoted by facilitation of data-driven decision making principles. The project extended EPIS by (1) elucidating the role and nature of recursive activity in promoting change (yielding the circular EPIS Wheel), (2) by expanding the applicability of the EPIS framework beyond a single evidence-based practice (EBP) to address varying process improvement efforts (representing varying EBPs), and (3) by disentangling outcome measures of progression through EPIS stages from the a priori established study timeline. DISCUSSION/CONCLUSIONS:The utilization of EPIS in JJ-TRIALS provides a model for practical and applied use of implementation frameworks in real-world settings that span outer service system and inner organizational contexts in improving care for vulnerable populations.

HIV and symptoms of depression are independently associated with impaired glucocorticoid signaling

Bekhbat, Mandakh; Mehta, C Christina; Kelly, Sean D; Vester, Aimee; Ofotokun, Ighovwerha; Felger, Jennifer; Wingood, Gina; Anastos, Kathryn; Gustafson, Deborah R; Kassaye, Seble; Milam, Joel; Aouizerat, Bradley; Weber, Kathleen; Golub, Elizabeth T; Moore, Michelle Floris; Diclemente, Ralph; Fischl, Margaret; Kempf, Mirjam-Colette; Maki, Pauline; Neigh, Gretchen N
Chronic inflammation caused by HIV infection may lead to deficient glucocorticoid (GC) signaling predisposing people living with HIV to depression and other psychiatric disorders linked to GC resistance. We hypothesized that comorbid HIV and depressive symptoms in women would synergistically associate with deficits in GC signaling. This cross-sectional study used samples obtained from the Women's Interagency HIV Study (WIHS). The Centers for Epidemiological Studies (CES-D) was used to define depression in four groups of women from the Women's Interagency HIV Study (WIHS): 1) HIV-negative, non-depressed (n = 37); 2) HIV-negative, depressed (n = 34); 3) HIV-positive, non-depressed (n = 38); and 4) HIV-positive, depressed (n = 38). To assess changes in GC signaling from peripheral blood mononuclear cells (PBMCs), we examined baseline and dexamethasone (Dex)-stimulated changes in the expression of the GC receptor (GR, gene: Nr3c1) and its negative regulator Fkbp5 via quantitative RT-PCR. GR sensitivity was evaluated in vitro by assessing the Dex inhibition of lipopolysaccharide (LPS)-stimulated IL-6 and TNF-α levels. Depressive symptoms and HIV serostatus were independently associated with elevated baseline expression of Fkbp5 and Nr3c1. Depressive symptoms, but not HIV status, was independently associated with reduced LPS-induced release of IL-6. Counter to predictions, there was no interactive association of depressive symptoms and HIV on any outcome. Comorbid depressive symptoms with HIV infection were associated with a gene expression and cytokine profile similar to that of healthy control women, a finding that may indicate further disruptions in disease adaptation.

Theory-Based Analysis of Interest in an HIV Vaccine for Reasons Indicative of Risk Compensation Among African American Women

Painter, Julia E; Temple, Brandie S; Woods, Laura A; Cwiak, Carrie; Haddad, Lisa B; Mulligan, Mark J; DiClemente, Ralph J
Licensure of an HIV vaccine could reduce or eliminate HIV among vulnerable populations. However, vaccine effectiveness could be undermined by risk compensation (RC), defined by an increase in risky behavior due to a belief that the vaccine will confer protection. Interest in an HIV vaccine for reasons indicative of RC may serve as an indicator of actual RC in a postlicensure era. This study assessed factors associated with interest in an HIV vaccine for reasons indicative of RC among African American women aged 18 to 55 years, recruited from a hospital-based family planning clinic in Atlanta, Georgia ( N = 321). Data were collected using audio-computer-assisted surveys. Survey items were guided by risk homeostasis theory and social cognitive theory. Multivariable logistic regression was used to assess determinants of interest in an HIV vaccine for reasons indicative of RC. Thirty-eight percent of the sample expressed interest in an HIV vaccine for at least one reason indicative of RC. In the final model, interest in an HIV vaccine for reasons indicative of RC was positively associated with higher impulsivity, perceived benefits of sexual risk behaviors, and perceived benefits of HIV vaccination; it was negatively associated with having at least some college education, positive future orientation, and self-efficacy for sex refusal. Results suggest that demographic, personality, and theory-based psychosocial factors are salient to wanting an HIV vaccine for reasons indicative of RC, and underscore the need for risk-reduction counseling alongside vaccination during the eventual rollout of an HIV vaccine.
