• We're in this together: Promoting health equity, diversity, and inclusion in tobacco research for sexual and gender minority populations. Nicotine & tobacco research : official journal of the Society for Research on Nicotine and Tobacco Dermody, S. S., Heffner, J. L., Hinds, J. T., McQuoid, J., Quisenberry, A. J., Tan, A. S., Vogel, E. A. 2020

  Abstract

  Sexual and gender minority (SGM) individuals have higher tobacco use prevalence and consequently higher burden of tobacco-caused diseases including cancer and cardiovascular disease compared with their heterosexual or cisgender counterparts. Yet, there is a critical gap in research focused on measuring SGM tobacco-related health disparities and addressing unmet needs of SGM individuals in the context of nicotine and tobacco research. In this commentary, we summarize recommendations discussed during a preconference workshop focused on challenges and opportunities in conducting SGM tobacco control research at the 2019 Society for Research on Nicotine and Tobacco Annual Meeting. Specifically, we recommend defining and measuring SGM identity in all nicotine and tobacco research routinely, using novel methods to engage a demographically diverse sample of the SGM population, and eliciting SGM community voices in tobacco control research. Addressing these critical research gaps will enable the scientific community to generate the data to fully understand and support SGM individuals in tobacco use prevention and cessation.

• Effects of Social Media on Adolescents' Willingness and Intention to Use E-Cigarettes: An Experimental Investigation. Nicotine & tobacco research : official journal of the Society for Research on Nicotine and Tobacco Vogel, E. A., Ramo, D. E., Rubinstein, M. L., Delucchi, K. L., Darrow, S., Costello, C., Prochaska, J. J. 2020

  Abstract

  This study examined effects of experimentally manipulated social media exposure on adolescents' willingness and intention to use e-cigarettes.Participants were 135 adolescents age 13-18 (52.6% female, M age=15.3) in California. Participants viewed 6 social media posts online in a 2 (post source: peer or advertisement) X 2 (e-cigarette content exposure: heavy or light) between-subjects design. Analyses were weighted to population benchmarks. We examined adolescents' beliefs, willingness, and intention to use e-cigarettes in association with social media use intensity in daily life and with experimentally manipulated exposure to social media posts that varied by source (peer or advertisement) and content (e-cigarette heavy or light).Greater social media use in daily life was associated with greater willingness and intention to use e-cigarettes and more positive attitudes, greater perceived norms, and lower perceived danger of e-cigarette use (all p-values<.01). In tests of the experimental exposures, heavy (versus light) e-cigarette content resulted in greater intention (p=.049) to use e-cigarettes and more positive attitudes (p=.019). Viewing advertisements (versus peer-generated posts) resulted in greater willingness and intention (p-values<.01) to use e-cigarettes, more positive attitudes (p=.003), and greater norm perceptions (p=.009). The interaction effect of post source by post content was not significant for any of the outcomes (all p-values>0.529).Greater social media use and heavier exposure to advertisements and e-cigarette content in social media posts are associated with a greater risk for e-cigarette use among adolescents. Regulatory action is needed to prohibit sponsored e-cigarette content on social media platforms used by youth.

• Strategies to improve treatment utilization for substance use disorders: A systematic review of intervention studies. Drug and alcohol dependence Vogel, E. A., Ly, K., Ramo, D. E., Satterfield, J. 2020; 212: 108065

  Abstract

  Many people who need specialty treatment for substance use disorders (SUDs) do not receive it. Clinical interventions could increase treatment utilization but are not routinely used. This systematic review aimed to describe clinical interventions that may increase SUD specialty treatment utilization (i.e., treatment initiation, attendance, meaningful engagement) and to determine which intervention(s) most consistently increase treatment utilization.We conducted a systematic review of clinical intervention studies (published in English between 2000 and 2017) reporting outcomes relevant to specialty SUD treatment utilization. Outcomes were treatment initiation, attendance, and meaningful engagement. Risk of bias was assessed using Cochrane guidelines and randomized controlled trials (RCTs) with bias scores < 3 were included in a synthesis of results. Proportions of positive to negative utilization outcomes were calculated for each low-bias RCT; studies with 50% positive outcomes or more were considered "majority-positive". Studies were categorized by theory-based approach.Twenty-three RCTs had low risk of bias and were synthesized. Among intervention types with two or more studies, cognitive-behavioral (100% majority-positive) and coordinated care (67% majority-positive) interventions were most likely to increase treatment initiation, while 12-step promotion interventions were most likely to increase treatment attendance (50% majority-positive). One study (12-step promotion) measured meaningful engagement, with majority-positive outcomes.A systematic review and narrative synthesis of clinical interventions promoting specialty SUD treatment utilization provided preliminary evidence that cognitive-behavioral and coordinated care interventions may increase treatment initiation, while 12-step promotion interventions may promote treatment attendance. More quality studies and greater consistency in treatment utilization measurement are needed.

• Prevalence of Electronic Cigarette Dependence Among Youth and Its Association With Future Use. JAMA network open Vogel, E. A., Cho, J., McConnell, R. S., Barrington-Trimis, J. L., Leventhal, A. M. 2020; 3 (2): e1921513

  Abstract

  Understanding the prevalence and symptoms of electronic cigarette (e-cigarette) dependence and its association with future e-cigarette use among youth may help to guide pediatric clinical services and health policy.To examine the cross-sectional prevalence and symptom presentation of e-cigarette dependence and to determine whether e-cigarette dependence is associated with subsequent e-cigarette use patterns 6 months later among youth with baseline past-year e-cigarette use.This prospective cohort study used baseline and 6-month follow-up surveys among students in the 12th grade during the 2016 to 2017 school year who reported any past-year e-cigarette use. Surveys were conducted on site in 10 high schools in Los Angeles, California. Data were analyzed from March 2019 to December 2019.Self-reported checklist of 10 tobacco product dependence symptoms reflecting loss of control over use, craving or urge, or withdrawal symptoms while abstinent, completed at baseline and administered separately for e-cigarettes and combustible cigarettes. Reporting 1 or more symptoms indicated a positive screen for dependence. Vaping continuation, defined as any past 6-month vaping, and past 30-day nicotine vaping days (range, 0-30), sessions per vaping day (range, 0-20), and puffs per session (range, 0-20) at 6-month follow-up were assessed.Among 3168 twelfth-grade students who completed the baseline survey, 444 youths (mean [SD] age, 17.48 [0.39] years; 217 [48.9%] female) reported past-year e-cigarette use. Among these, 52 youths (11.7%) reported at least 1 e-cigarette dependence symptom. Among youth who reported past-year dual e-cigarette and combustible cigarette use, combustible cigarette dependence, reported by 43 youths (29.7%), was more prevalent than e-cigarette dependence, which was reported by 24 youths (16.4%). The most common symptoms, craving, urge, and need to use, and least common symptoms, abstinence-related concentration and emotional problems, were similar in both combustible and e-cigarette dependence. The prevalence of e-cigarette dependence was higher among youth who reported vaping in the past month than among those who did not (41 youths [17.6%] vs 11 youths [5.2%]; P < .001) and among youth who used e-cigarettes with nicotine than among those who used e-cigarettes without nicotine (42 youths [15.2%] vs 10 youths [6.0%]; P = .004). After adjusting for baseline vaping and e-cigarette dependence risk propensity scores, baseline e-cigarette dependence symptom status was associated with vaping continuation (adjusted odds ratio, 2.30 [95% CI, 1.07-4.94]; P = .02) and past 30-day number of nicotine vaping days (adjusted rate ratio, 2.17 [95% CI, 1.44-3.28]; P < .001), vaping sessions per day (adjusted rate ratio, 2.41 [95% CI, 1.52-3.83]; P < .001), and puffs per session (adjusted rate ratio, 1.70 [95% CI, 1.09-2.66]; P = .02) at 6-month follow-up.These findings suggest that e-cigarette dependence may be an expression of tobacco use disorder associated with future use persistence and escalation among youth. Electronic cigarette dependence may be a behavioral health consequence of adolescent vaping that warrants consideration in pediatric patient care and public health policy.

• Adolescents' E-Cigarette Use: Increases in Frequency, Dependence, and Nicotine Exposure Over 12Months. The Journal of adolescent health : official publication of the Society for Adolescent Medicine Vogel, E. A., Prochaska, J. J., Ramo, D. E., Andres, J., Rubinstein, M. L. 2019; 64 (6): 770–75

  Abstract

  PURPOSE: This study examined changes in e-cigarette and dual-use frequency, levels of nicotine exposure and e-cigarette dependence, and device and e-liquid preferences over 12months.METHODS: Adolescents (N= 173, aged 13-18 years) who reported past-month e-cigarette use and at least 10 lifetime uses were recruited from the San Francisco Bay Area. The sample was 75.1% male, 54.9% non-Hispanic White, mean age 16.6years (standard deviation= 1.2); 26.6% reported past-month cigarette smoking at baseline (i.e., dual use). At baseline, 6-month, and 12-month follow-up, participants provided saliva samples for cotinine testing and self-reported e-cigarette use frequency, dependence, past-month smoking, product preference, and flavor preference.RESULTS: Most (80.3%) were still using e-cigarettes at 12 months, and daily use increased from 14.5% to 29.8%. Model testing indicated an overall increase from baseline to 12months in frequency of e-cigarette use (F(2, 166)= 5.69, p= .004), dependence (F(2, 164)= 5.49, p= .005), and cotinine levels (F(2, 103)= 4.40, p= .038). Among those reporting only e-cigarette use at baseline, 28.8% reported combustible cigarette use during follow-up. Among those reporting dual use at baseline, 57.1% were still dual using at 12 months, 31.4% reported e-cigarette use only, and none abstained from both products. Higher nicotine delivering e-cigarette devices (i.e., Juul, mods) became more popular over time, whereas flavor preferences (i.e., fruit, mint/menthol, and candy) remained stable.CONCLUSIONS: Adolescents' e-cigarette use persisted over a 12-month period with significant increases in frequency of use, nicotine exposure, and e-cigarette dependence. Transitions from single to dual and dual to single nicotine product use were observed in approximately one in three users over the study period.

• Development and acceptability testing of a Facebook smoking cessation intervention for sexual and gender minority young adults. Internet interventions Vogel, E. A., Belohlavek, A., Prochaska, J. J., Ramo, D. E. 2019; 15: 87–92

  Abstract

  This study tested engagement in and acceptability of a digital smoking cessation intervention designed for young adults and tailored to sexual and gender minority (SGM) individuals. The intervention included 90 Facebook posts delivered in private groups tailored to readiness to quit smoking (Ready to quit in 30 days/Not Ready; 180 posts total; 101 posts SGM-tailored by content/image). Acceptability was evaluated over 30 days (3 posts/day). Participants' (N = 27) open-ended feedback was coded and tallied; posts with significant negative feedback were flagged for change. Flags and comment volume were examined by SGM tailoring (versus not tailored) and content category (motivational interviewing, experiential strategies, behavioral strategies, relevant topics). Engagement and acceptability were high. All participants reported viewing at least half of the posts, and the majority reported viewing all 90 posts (M comments per participant = 51.74). The majority of participants agreed or strongly agreed with statements about the intervention's helpfulness and clarity. Posts received an average of 8.08 comments (SD = 2.58), with 59 posts (32.8%) flagged for change. Posts engaged comments and were found to be acceptable at comparable levels regardless of SGM tailoring and content category (all p-values > .189). SGM young adult smokers were highly engaged in an SGM-tailored smoking cessation intervention on Facebook and rated the intervention positively. Both tailored and non-tailored Facebook posts in a variety of content areas were generally well-received by SGM young adults, an underserved population with high rates of smoking.

• Smoking Cessation Intervention Trial Outcomes for Sexual and Gender Minority Young Adults HEALTH PSYCHOLOGY Vogel, E. A., Thrul, J., Humfleet, G. L., Delucchi, K. L., Ramo, D. E. 2019; 38 (1): 12–20

  Abstract

  Sexual and gender minority (SGM) individuals are more likely to smoke than are non-SGM individuals. It is unclear whether smoking cessation interventions for young adults are effective in the SGM population. The purpose of this study was to compare smoking cessation, other health risk behaviors, and intervention usability between SGM and non-SGM young adult smokers participating in a digital smoking cessation intervention trial.Young adult smokers (N = 500; 135 SGM) were assigned to a 90-day Facebook smoking cessation intervention (treatment) or referred to Smokefree.gov (control). Intervention participants were assigned to private Facebook groups tailored to their readiness to quit smoking. Participants reported their smoking status and other health risk behaviors at baseline, 3, 6, and 12 months. Usability of the intervention (i.e., perceptions of the intervention and treatment engagement) was assessed in the intervention group at 3 months.Smoking cessation and intervention usability did not significantly differ between SGM participants and non-SGM participants. A greater proportion of SGM participants were at high risk for physical inactivity over the 12-month follow-up period (odds ratio [OR] = 1.55, p = .005).SGM and non-SGM young adult smokers did not differ in their smoking cessation rates, perceptions of, or engagement in a digital intervention. Health risk behavior patterns were mostly similar; however, the disparity in physical activity between SGM and non-SGM smokers widened over time. Tailored interventions for SGM young adult smokers could increase focus on SGM experiences that can underlie multiple health risk behaviors, such as discrimination and the normativity of smoking.

• The Put It Out Project (POP) Facebook Intervention for Young Sexual and Gender Minority Smokers: Outcomes of a Pilot Randomized Controlled Trial. Nicotine & tobacco research : official journal of the Society for Research on Nicotine and Tobacco Vogel, E. A., Ramo, D. E., Meacham, M. C., Prochaska, J. J., Delucchi, K. L., Humfleet, G. L. 2019

  Abstract

  This trial investigated whether a Facebook smoking cessation intervention culturally tailored to young sexual and gender minority (SGM) smokers (versus non-tailored) would increase smoking abstinence.Participants were 165 SGM young adult U.S. smokers (age 18-25) recruited from Facebook in April 2018 and randomized to an SGM-tailored (POP; N=84) or non-tailored (TSP-SGM; N=81) intervention. Interventions delivered weekly live counseling sessions and 90 daily Facebook posts to participants in Facebook groups. Primary analyses compared POP and TSP-SGM on biochemically verified smoking abstinence (yes/no; primary outcome), self-reported 7-day point prevalence abstinence (yes/no), reduction in cigarettes per week by 50+% from baseline (yes/no), making a quit attempt during treatment (yes/no), and stage of change (precontemplation/contemplation vs. preparation/action). Supplemental analyses compared POP to two historical control groups.POP participants were more likely than TSP-SGM participants to report smoking abstinence at 3 (23.8% vs. 12.3%; OR=2.50; p=.03) and 6 months (34.5% vs. 12.3%; OR=4.06; p<.001) and reduction in smoking at 3 months (52.4% vs. 39.5%; OR=2.11; p=.03). Biochemically verified smoking abstinence did not significantly differ between POP and TSP-SGM at 3 (OR=2.00; p=.33) or 6 months (OR=3.12; p=.08), potentially due to challenges with remote biochemical verification. In supplemental analyses, POP participants were more likely to report abstinence at 3 (OR=6.82, p=.01) and 6 (OR=2.75, p=.03) months and reduced smoking at 3 months (OR=2.72, p=.01) than participants who received a referral to Smokefree.gov.This pilot study provides preliminary support for the effectiveness of a Facebook smoking cessation intervention tailored to SGM young adults.Sexual and gender minority (SGM) individuals have disproportionately high smoking prevalence. It is unclear whether smoking cessation interventions culturally tailored to the SGM community are more effective than non-tailored interventions. This pilot trial found preliminary evidence that an SGM-tailored Facebook smoking cessation intervention increased reported abstinence from smoking, compared to a non-tailored intervention.

• Multiple Health Risk Behaviors in Young Adult Smokers: Stages of Change and Stability over Time. Annals of behavioral medicine : a publication of the Society of Behavioral Medicine Ramo, D. E., Thrul, J., Vogel, E. A., Delucchi, K., Prochaska, J. J. 2019

  Abstract

  Health risk behaviors (HRBs) are common, yet not well understood in young adult smokers.We examined HRB profiles over 12 months in young adult smokers participating in a Facebook smoking cessation intervention clinical trial.Participants (N = 500; age M = 20.9 years; 54.6% women) were recruited online and randomized to receive either a 3-month Facebook smoking cessation intervention or referral to Smokefree.gov (control). A Health Risk Assessment determined risk for 10 behaviors at baseline and 3, 6, and 12 months. Latent class analysis (LCA) and latent transition analysis (LTA) were used to identify patterns of HRBs and changes over time.At baseline, participants reported an average of 5.4 (standard deviation [SD] = 1.7) risk behaviors, including smoking (100%), high-fat diet (84.8%), poor sleep hygiene (71.6%), and low fruit and vegetable intake (69.4%). A 3-class model fit the data best at baseline and all follow-up time points: low risk (28.8% at baseline) with low likelihood of risk on all behaviors except smoking, substance use risk (14.0% at baseline) characterized by heavy episodic drinking, cannabis use, and other illicit drug use, and metabolic risk (57.2% at baseline), with a high percentage of members at risk for a low fruit and vegetable intake, high-fat diet, inactivity, stress, and poor sleep hygiene. Classes were very stable at 3, 6, and 12 months, with few participants transitioning between classes.Most young adult smokers engaged in multiple risk behaviors, with meaningful clustering of behaviors, and demonstrated stability over a year's time. In addition to smoking, targets for intervention are co-occurring substance use and metabolic risk behaviors.NCT02207036.

• Associations between marijuana use and tobacco cessation outcomes in young adults JOURNAL OF SUBSTANCE ABUSE TREATMENT Vogel, E. A., Rubinstein, M. L., Prochaska, J. J., Ramo, D. E. 2018; 94: 69–73

  Abstract

  Marijuana and tobacco co-use is common among young adults, and findings are mixed regarding the association between marijuana use and smoking cessation outcomes. This study examined the longitudinal relationships between marijuana use and smoking cessation outcomes among young adults (aged 18-25 years; N = 500) enrolled in a 3-month smoking cessation intervention on Facebook. At baseline and 3, 6, and 12 months, participants reported their marijuana use and their smoking behaviors (seven-day point prevalence abstinence from smoking, cigarettes per day, quit attempts) and readiness to quit. Longitudinal analyses controlled for experimental condition and adjusted for baseline stage of change, baseline average cigarettes per day, sex, alcohol use, and age participants began smoking regularly. Use of marijuana by young adult smokers was associated with a lower likelihood of reduced smoking (OR = 0.71, 95% CI [0.51, 0.98], p = .036) and a lower likelihood of abstaining from smoking (OR = 0.56, 95% CI [0.35, 0.90], p = .017) in the past seven days, as assessed over 12 months of follow-up. Use of marijuana was not significantly associated with perceptions of or engagement in the smoking cessation intervention, stage of change for quitting smoking, or tobacco quit attempts (all p's > 0.08). Study findings indicate that while marijuana use is unrelated to motivation to quit tobacco and engage in cessation interventions, marijuana use is associated with less success in reducing and abstaining from tobacco. Additional support and targeted tobacco cessation strategies to address challenges associated with marijuana co-use may be needed.

• Prevalence and correlates of adolescents' e-cigarette use frequency and dependence DRUG AND ALCOHOL DEPENDENCE Vogel, E. A., Ramo, D. E., Rubinstein, M. L. 2018; 188: 109–12

  Abstract

  Understanding predictors of e-cigarette use among adolescents in the context of wide availability and extreme popularity of these products is important for prevention and treatment. This study identifies correlates of e-cigarette use frequency and dependence among adolescent users.Adolescent e-cigarette users (N = 173) were recruited from the San Francisco Bay Area. Participants reported demographic and psychosocial characteristics, e-cigarette use behaviors, and cigarette use. Bivariate relationships between potential correlates were examined, and correlates significant at p < .10 were included in full models predicting frequency and dependence.In the full models, frequent use was associated with receiving one's first e-cigarette from a family member rather than a friend (r = -0.23, p < .001) or a store ( = -0.13, p = .037), using nicotine in all e-cigarettes versus some e-cigarettes (r = -0.17, p = .007) or unknown nicotine use (r = -0.15, p = .014), using a customizable device versus a Juul (r = -0.22, p < .001), vape pen (r = -0.20, p = .002), or other/unknown device (r = -0.16, p = .009), and friends' e-cigarette use (r = 0.20, p = .002). Dependence was associated with younger age of first use (r = -0.18, p = .012), friends' use (r = 0.18, p = .01), and recent cigarette use (r = 0.17, p = .019).When assessing problematic e-cigarette use among adolescents, it is important to consider social factors (e.g., friends' and family members' e-cigarette use), device type, and dual use with cigarettes.

• The Application of Persuasion Theory to Placebo Effects NEUROBIOLOGY OF THE PLACEBO EFFECT, PT I Geers, A. L., Brinol, P., Vogel, E. A., Aspiras, O., Caplandies, F. C., Petty, R. E., Colloca, L. 2018; 138: 113–36

  Abstract

  Placebo effects, or positive outcomes resulting from expectations about a treatment, are powerful components of modern medical care. In this chapter, we suggest that our understanding of placebo effects may benefit from more explicitly connecting this phenomenon to the existing empirical psychological literature on persuasion. Persuasion typically involves an attempt to bring about a change in beliefs or attitudes as a result of providing information on a topic. We begin by providing a brief overview of the psychological literature on placebo effects. We then point to connections between this literature and research on persuasive communication. Although some links have been made, these initial connections have predominantly relied on classic theories of persuasion rather than on more contemporary and comprehensive models. Next, we describe a modern theory of persuasion that may facilitate the study of placebo effects and analyze two issues pertinent to the literature on placebo effects from the lens of this model. Specifically, we consider how and when characteristics of a practitioner (e.g., variables such as perceptions of a practitioner's confidence or competence) can influence the magnitude of placebo effects, and how modern persuasion theory can help in understanding the durability of placebo effects over time. We conclude that examining placebo effects as an outcome of persuasive communication would be a fruitful line of future research.

• "Transformation Tuesday": Temporal context and post valence influence the provision of social support on social media JOURNAL OF SOCIAL PSYCHOLOGY Vogel, E. A., Rose, J. P., Crane, C. 2018; 158 (4): 446–59

  Abstract

  Social network sites (SNSs) such as Facebook have become integral in the development and maintenance of interpersonal relationships. Users of SNSs seek social support and validation, often using posts that illustrate how they have changed over time. The purpose of the present research is to examine how the valence and temporal context of an SNS post affect the likelihood of other users providing social support. Participants viewed hypothetical SNS posts and reported their intentions to provide social support to the users. Results revealed that participants were more likely to provide social support for posts that were positive and included temporal context (i.e., depicted improvement over time; Study 1). Furthermore, this research suggests that visual representations of change over time are needed to elicit social support (Study 2). Results are discussed in terms of their practical implications for SNS users and theoretical implications for the literature on social support and social media.

• Experiencing is believing: prior experience moderates the impact of self-based and socially-based cues in the context of blood donation JOURNAL OF BEHAVIORAL MEDICINE Roberts, L., Rose, J. P., Vogel, E. A. 2017; 40 (6): 998–1010

  Abstract

  Two studies explored how self-based cues (i.e., self-efficacy), socially-based cues (i.e., perceived social norms), and prior blood donation experience differentially influence behavioral intentions. In Study 1, undergraduate students (N = 766) completed an online study that evaluated prior experiences, self-efficacy, perceived norms, and behavioral intentions in the context of blood donation. In Study 2, a community sample (N = 199) from a clinic waiting room completed similar measures. Across both studies, having high self-efficacy was a necessary and sufficient antecedent to high intentions, regardless of norm perception for donors. For non-donors, however, high self-efficacy was necessary but not sufficient; non-donors' intentions were higher when giving blood was perceived to be normative, but far lower when it was not. When self-efficacy was low, the effects of experience and norms did not exert meaningful effects and donation intentions were quite low. These results demonstrate that the impact of self-based and socially-based cues on behavioral intentions may differ as a function of experience. The findings can inform public health initiatives and enhance the accuracy of theoretical models by directly examining experience as a moderator.
