Bidirectional Associations Between Pain and Perceived Stress Among Veterans: Depressive Disorder as a Predisposing Factor.

OBJECTIVE: Military veterans who were injured in combat very often report pain along with co-occurring perceived stress and preexisting depressive disorder. The systems model of pain is a theoretical model suggesting that pain and perceived stress are bidirectionally associated at the within-person level, and associations are heightened among those with depressive disorder. However, the systems model of pain has not been adequately tested. Testing the systems model of pain could illuminate salient treatment targets for combat-injured veterans with pain and co-occurring psychological problems. METHODS: The present study empirically tests the systems model of pain among a sample of combat-injured veterans ( N = 902) surveyed five times during an 18-month period. We used a multigroup, autoregressive latent trajectory with structured residual statistical model to test the within-person associations between pain and perceived stress and determine whether associations differ between veterans with and without a positive screen for depressive disorder. RESULTS: In line with the systems model of pain, pain and perceived stress were bidirectionally associated only among combat-injured veterans with depressive disorder. Among such veterans, perceived stress was positively associated with subsequent pain ( b = 0.12; 95% confidence interval = 0.06-0.17), and pain was positively associated with subsequent perceived stress ( b = 0.44; 95% CI = 0.11-0.77). CONCLUSIONS: Our work highlights the interplay between pain and its psychological correlates among a particularly at-risk population. Clinicians addressing pain and perceived stress among combat-injured veterans should be prepared to identify and address depressive disorder.

Longitudinal associations between insomnia, cannabis use and stress among US veterans.

Insomnia is highly prevalent among military veterans, with rates nearly double that of civilian populations. Insomnia typically co-occurs with other psychological problems, including substance use (e.g. cannabis) and perceived stress. Much of the research focused on insomnia, stress and cannabis use explores cannabis as a sleep aid and a mechanism for stress relief. However, recent theoretical and empirical evidence suggests a dynamic interplay between insomnia, cannabis use and perceived stress, yet few longitudinal studies exist. Using a sample of 1105 post-9/11 veterans assessed over four time points across 12 months, we used latent difference score modelling to examine proportional change between insomnia, perceived stress and cannabis use. Results revealed a complex interplay between all three constructs. In particular, we show that higher prior levels of insomnia are associated with greater increases in perceived stress, and greater prior levels of stress are associated with greater increases in cannabis use. Perhaps more importantly, our results also point to cannabis use as a catalyst for greater increases in both stress and insomnia severity. Our results suggest there may be both benefits and costs of cannabis use among veterans. Specifically, for veterans who experience chronic sleep problems, perceived stress may become overwhelming, and the benefit of stress reduction from increased cannabis use may come at the cost of increasing insomnia symptomology.

Sociodemographic and Behavioral Risk Correlates of PrEP Interest and Use Among Young Adults Experiencing Homelessness in Los Angeles.

Young adults experiencing homelessness (YAEH) are at elevated risk for HIV compared to their stably housed peers. Preexposure prophylaxis (PrEP) is highly effective at preventing HIV infection, yet YAEH have been largely overlooked in PrEP efforts to date despite YAEH reporting high overall interest in PrEP. We assessed individual, social, and structural variables associated with PrEP interest and use among a sample of 195 YAEH (ages 18-25) recruited from drop-in centers across Los Angeles County who met criteria for HIV risk. In the current sample, though most had heard of PrEP (81.0%), the majority were not interested in taking PrEP (68.2%) and only a minority had used/were using PrEP (11.8%). YAEH who identified as sexual and/or gender minority, reported knowing someone who had used PrEP, or recently accessed sexual health services were more likely to have used and/or reported interest in using PrEP. Those who reported more episodes of heavy drinking were less likely to report having used PrEP. Suggestions are provided for better integrating PrEP-related services into existing behavioral and health service programs for YAEH, as well as leveraging peers and fostering positive social norms to reduce PrEP-related stigma and increase interest and use of PrEP among YAEH.

Association of over the counter "hangover remedy" use with alcohol use problems and consumption patterns among young adults.

This cross-sectional study of young adults examined associations of hangover remedy use with alcohol use problems. Results suggest that ever-use of hangover remedy products was positively associated with alcohol use problem score, drinks per typical drinking day, and alcohol use disorder symptom count. Use of hangover remedies among young adults merits further scientific and regulatory attention.

Alcohol use disorder, cannabis use disorder, and eating disorder symptoms among male and female college students.

BACKGROUND AND OBJECTIVES: Eating disorders (EDs) and substance use disorders are prevalent among college students in the United States, with underlying common mechanisms suggesting co-occurrence of these in the student population. As treatment prognosis of EDs improves when they are identified and treated with early intervention, it is essential to understand which substance use behaviors associate with EDs in students. METHODS: Using a sample of 471 college students recruited for a study on high risk drinking (i.e., students needed to pregame regularly to be included), we explored the associations between ED symptomatology and two common substances used in this population: alcohol and cannabis. As most research on EDs focuses on female students only or does not separate out males and females, we examined whether sex assigned at birth moderated the association between ED symptomatology and substance use outcomes. RESULTS: About one-third (32.4%) of the sample screened positive for an ED, with females significantly more likely to screen positive. Males were significantly more likely to screen positive for an alcohol or cannabis use disorder. Screening positive for an ED associated with cannabis use frequency and cannabis use disorder symptoms, but not with alcohol outcomes. Sex moderated the association between ED and cannabis use disorder symptoms, with positive ED screen male students experiencing the highest cannabis use disorder symptoms. DISCUSSION AND CONCLUSIONS: It is necessary to further assess how sex differences in substance use and ED symptomatology inform each other. SCIENTIFIC SIGNIFICANCE: Findings underscore the need to assess and screen for cannabis use disorder among students who screen positive for an ED, and, more specifically, with focused attention on male students with ED symptoms.

Longitudinal associations among experiences of sexual assault, posttraumatic stress disorder symptoms, and heavy drinking in young adults.

Prior research with young adults has demonstrated clear associations between experiences of sexual assault, symptoms of posttraumatic stress disorder (PTSD), and alcohol use, but most studies have been cross-sectional or have not considered multiple theoretical pathways to understand these associations. Using six waves of data from a longitudinal cohort sample of 1,719 young adults, we examined associations among experiences of past-year sexual assault (i.e., rape, unwanted sexual touching, and physical intimidation in a sexual way), PTSD symptoms, and the frequency of binge drinking over time, allowing for the exploration of symptom-induced, interpersonal risk, and substance-induced pathways for male and female participants. For both male, ßs = 2.84 to 6.55, and female participants, ßs = 2.96 to 10.1, higher prior levels of PTSD symptoms were associated with larger increases in binge drinking over time. For female participants, higher prior levels of sexual assault were associated with larger increases in PTSD symptoms over time, ßs = 3.48 to 4.25, whereas for male participants, higher prior levels of past-year binge drinking were associated with decreases in PTSD symptoms over time, ßs = -2.75 to -0.53. Continued efforts are needed to prevent sexual assault among young adults and address PTSD symptoms among those who experience sexual assault. Interventions that target binge drinking are also needed for individuals who experience PTSD symptoms, especially young adults, to address potentially hazardous drinking before problems escalate and become chronic.

Using Latent Profile Analysis to Examine Cannabis Use Contexts: Associations with Use, Consequences, and Protective Behaviors.

OBJECTIVE: College students represent a large portion of the population, and report high rates of cannabis use and related negative outcomes, including interpersonal problems, risky behaviors, or physical dependency. The contexts in which students use cannabis (e.g., at a party, when feeling down or depressed, after a fight with a loved one) likely affect their risk of experiencing consequences. We aimed to discern profiles of cannabis use contexts and compare profiles on use frequency, consequences, and the use of cannabis protective behavioral strategies (PBS). METHOD: College students were surveyed regarding their cannabis use contexts, frequency, consequences, and PBS use (n = 265; female = 72.8%). We used Latent Profile Analysis to identify patterns of cannabis use contexts and auxiliary testing to compare profiles on use frequency, consequences, and PBS use. RESULTS: Our examination revealed three latent profiles of cannabis use. The Social Use Profile was associated with use in predominantly social/uplifting contexts. The Physical & Emotional Pain Profile was also associated with use in these contexts but was defined by additional use in response to pain. The All Contexts Profile was associated with frequent use in all contexts, including those that were least endorsed by the other profiles. Profiles differed in cannabis use frequency, PBS use, and the number of consequences experienced, such that profiles were more likely to be associated with more frequent cannabis use, higher risk of experiencing use-consequences, and using fewer PBS as the number of use contexts increased across the profiles. CONCLUSIONS: The contexts in which people use cannabis are associated with cannabis risk and protection. Prevention and intervention efforts may benefit from considering contexts of cannabis use.

Sexual Violence Victimization and Pregaming Protective Behavioral Strategies Among College Students.

BACKGROUND: Sexual violence is a major public health concern that has a detrimental impact on mental health, physical health, and academic performance. College students represent a population that is at an increased risk of experiencing sexual violence. Alcohol use, and more specifically, heavy drinking during pregaming events, is associated with increased risk of sexual violence. Studies have demonstrated that protective behavioral strategies have effectively reduced heavy drinking and the risk of alcohol-related consequences, including sexual violence victimization. OBJECTIVES: This study aims to examine the association between experiences of sexual violence in college and subsequent use of pregaming protective strategies. RESULTS: Data from 468 college students (67% female, 33% male) were analyzed. Over 42% of participants reported experiencing sexual violence in college. While adjusting for pregaming frequency and sex, results revealed that those who reported experiencing sexual violence in college were significantly less likely to use pregaming protective behavioral strategies compared to those without such experiences. Specifically, survivors of sexual violence were less likely to report using the protective behavioral strategies of minimizing intoxication, as well as behaviors related to safety and familiarity (e.g., using a designated driver after pregaming). CONCLUSIONS: The findings have important implications for interventions aimed at empowering survivors of sexual violence. Future research should focus on understanding survivor's motives and mechanisms to use pregaming protective behavioral strategies to reduce the risk of re-victimization.

An Examination of Pregaming Behavior and Motives among Sexual and Gender Minority College Students.

Introduction: Pregaming is a popular but high-risk drinking behavior common among college students. Although sexual and gender minority (SGM) college students are a vulnerable population with regards to hazardous alcohol use and alcohol consequences, there is currently limited research investigating the pregaming behavior of this group. The present study aimed to (1) examine mean level differences in pregaming behaviors and motives between SGM and non-SGM college students and (2) explore how SGM status was associated with pregaming behaviors and if SGM status moderated the association between motives and pregaming behaviors. Methods: The sample consisted of 485 college student drinkers in the US, with 19% (n = 93) identifying as SGM. All participants completed measures of past 30-day pregaming frequency and quantity (yielding a total pregaming drinks outcome) and drinking consequences experienced on pregaming days. Results: SGM participants consumed significantly fewer pregaming drinks than non-SGM participants, but did not significantly differ on alcohol-related consequences or drinking motives. The pregaming motive of intimate pursuit moderated the association between SGM status and total pregaming drinks, such that non-SGM participants with high intimate pursuit motives drank the heaviest. Conclusions: Our findings suggest that SGM students consume significantly fewer pregaming drinks than their non-SGM counterparts. However, they may be at a similar risk of experiencing pregaming consequences as non-SGM students. SGM students were less susceptible to the effect of intimate pursuit motives on pregaming drink consumption. This study offers support for past research regarding the effects of certain pregaming motives on pregaming drink consumption and consequences.

A Deeper Dive into Young Adults' Experiences with E-Cigarettes, E-Cigarette Cessation, and Transitioning to Cigarette Smoking.

Introduction: E-cigarette use among young adults is prevalent, with some voicing their desire to quit using e-cigarettes but needing support to do so. Young adults who use e-cigarettes are at risk for progressing to smoking combustible cigarettes, placing them at risk for severe health consequences. Limited research exists describing young adults' lived experiences with using e-cigarettes, e-cigarette cessation, and progression to combustible cigarettes. Methods: Between July and August 2022, nine focus groups were conducted with 33 young adults who either (1) currently used e-cigarettes, (2) formerly used e-cigarettes, or (3) transitioned to cigarettes. Transcripts were coded and themes were identified independently by two research team members while a third researcher reviewed the coding and themes. Results: Participants described social influences, stress, and curiosity as primary reasons why they initiated e-cigarette use. The most reported negative experiences or consequences associated with e-cigarettes include the health effects, addiction, and financial costs. Participants who transitioned to cigarettes reported social influences, a desire to reduce or quit using e-cigarettes by replacing them with cigarettes, curiosity, and stress as the primary reasons for this progression to combustible cigarettes. Participants described barriers to quitting e-cigarettes, including social influences, withdrawal, and easy access to e-cigarettes, as well as facilitators of quitting, such as social support, change in environment, and finding healthier ways to manage stress. Conclusions: This qualitative work provides an in-depth look into factors that may be helpful in the development of prevention and intervention programs for both e-cigarette and combustible cigarette use in young individuals.

Associations between service use and behavioral health trajectories among young adults experiencing homelessness.

Purpose: To examine associations of service use (housing, mental health, substance use, education, and employment) with depression and substance use disorder (SUD) trajectories among young adults experiencing homelessness. Method: Secondary data come from 276 young adults who participated in an intervention to reduce substance use and sexual risk behaviors. Participants were recruited from three drop-in centers in Los Angeles County from 2018 to 2020, and completed surveys at baseline, 3-, 6-, 12-, and 24-months post-baseline. Latent growth curve models examined trajectories of depression and SUD; service use in the past three months was used to predict growth trajectories. Results: More frequent use of mental health services (but not other services) at baseline was associated with greater depression symptoms at baseline, linear declines in depression, and a quadratic increase in depression. Service use at baseline was not associated with likelihood of SUD at baseline or changes in SUD over time. Conclusions: Young adults in most need of behavioral services are likely to receive services for mental health, but not SUD. Use of mental health services may reduce depression symptoms over time, but continuing care may be needed to prevent symptom returns. More work is needed to connect young adults with SUD treatment and improve effectiveness of these services.

Childhood adversity, combat experiences, and military sexual trauma: a test and extension of the stress sensitization hypothesis.

BACKGROUND: U.S. veterans report high rates of traumatic experiences and mental health symptomology [e.g. posttraumatic stress disorder (PTSD)]. The stress sensitization hypothesis posits experiences of adversity sensitize individuals to stress reactions which can lead to greater psychiatric problems. We extend this hypothesis by exploring how multiple adversities such as early childhood adversity, combat-related trauma, and military sexual trauma related to heterogeneity in stress over time and, subsequently, greater risk for PTSD. METHODS: 1230 veterans were recruited for an observational, longitudinal study. Veterans responded to questionnaires on PTSD, stress, and traumatic experiences five times over an 18-month study period. We used latent transition analysis to understand how heterogeneity in adverse experiences is related to transition into stress trajectory classes. We also explored how transition patterns related to PTSD symptomology. RESULTS: Across all models, we found support for stress sensitization. In general, combat trauma in combinations with other types of adverse experiences, namely early childhood adversity and military sexual trauma, imposed a greater probability of transitioning into higher risk stress profiles. We also showed differential effects of early childhood and military-specific adversity on PTSD symptomology. CONCLUSION: The present study rigorously integrates both military-specific and early life adversity into analysis on stress sensitivity, and is the first to examine how sensitivity might affect trajectories of stress over time. Our study provides a nuanced, and specific, look at who is risk for sensitization to stress based on previous traumatic experiences as well as what transition patterns are associated with greater PTSD symptomology.

Cigarette Smoking and Depression Among U.S. Veterans: Longitudinal Associations With Posttraumatic Stress Disorder.

INTRODUCTION: Cigarette smoking and depression are associated with morbidity and mortality. Among veterans, approximately 22% are current smokers and 11%-15% have been diagnosed with depression. Although prior research suggests a strong association between smoking and depression among veterans, little research has examined trajectories of smoking and depressive symptoms and their correlates over time in this population. AIMS AND METHODS: Using parallel process growth curve modeling, we examined the longitudinal relationship between smoking and depression and tested whether posttraumatic stress disorder (PTSD) symptoms predict smoking and depression trajectories over 18 months (February 2020-August 2021). Veterans were recruited for an online, longitudinal study and responded to surveys across five-time points (baseline N = 1230; retention = 79.3%-83.3% across waves). RESULTS: Associations indicated that more frequent smoking at baseline was associated with steeper increases in depression symptom severity, and greater depression severity at baseline was associated with a less steep decrease in smoking frequency over time. PTSD was associated with less smoking at time 1 but more frequent smoking at times 3-5 as well as greater depression across all time points. CONCLUSIONS: Findings provide support that the growth trajectories of smoking and depression are linked, and PTSD symptoms are associated with these trajectories among veterans. Addressing these factors simultaneously in veteran treatment centers or through tobacco cessation efforts may be beneficial. IMPLICATIONS: This study offers strong evidence that the growth trajectories of smoking and depression are linked, and PTSD symptoms affect these trajectories among veterans, who represent a largely understudied population despite high rates of substance use and mental health problems. Results of this study strengthen the case for a more integrated treatment approach in which both smoking and mental health concerns are simultaneously addressed, which may yield more beneficial physical health and clinical outcomes for post-9/11 veterans.

Predictors of Functioning and Recovery Among Men and Women Veterans with Schizophrenia.

Gender differences may play a role in functional outcomes for individuals with schizophrenia. To better understand differences, an exploratory secondary analysis was conducted using data from a large, multi-site study of individuals with schizophrenia in treatment at Veterans Affairs medical centers. Participants completed surveys at baseline (n = 801; 734 men, 67 women) to assess demographics, symptoms, social supports, and recovery; and one year (n = 662; 604 men, 58 women) to assess quality of life and functioning. Hierarchical linear regressions examined interactions of baseline factors with functioning and quality of life. Women and men did not differ significantly in baseline social support, psychiatric symptoms, or recovery. Female gender predicted higher occupational functioning, while social functioning in men was inversely related to baseline symptom severity. Being married predicted higher quality of life for women, but not men. These findings may inform gender tailoring of services for schizophrenia.

Eating disorder risk among college sorority and fraternity members within the United States.

Eating disorder (ED) risk is elevated among college populations in the United States. However, current research assessing the relative risk of ED symptomatology within Greek life has been mixed. We aimed to assess whether Greek Life Affiliation (GA) was associated with a greater risk for ED among college students in the United States as measured on the SCOFF questionnaire. Data were extracted from the Healthy Minds Study, which surveyed 44,785 American college students across 79 schools. The survey asked about GA, Greek life housing, and included the SCOFF questionnaire. This study utilized multiple logistic regressions and chi-square analyses (n = 44785) to analyze the data. GA failed to predict ED-risk in both women (aOR = 0.98 [95% CI = 0.90, 1.06]) and men (aOR = 1.07 [95% CI = 0.92, 1.24]). Similarly, among female [aOR = 1.00 [95% CI = 0.46, 2.12]) and male participants (aOR = 1.06 [95% CI = 0.59, 1.98]), sorority/fraternity housing also failed to predict ED-risk. Greek Life Affiliation is not associated with greater ED-risk among US college students.

Associations between depression, stress, and e-cigarette use among OEF/OIF veterans.

The COVID-19 pandemic has had profound mental and behavioral health implications for the general U.S. population. However, little is known regarding outcomes for U.S. veterans, who represent a population with high rates of depression, stress, and e-cigarette use. One month prior to the pandemic-related closures (February 2020), 1230 OEF/OIF veterans (ages 18-40) completed an online baseline survey. Six months later, participants completed a follow-up survey (83% retention rate). Hierarchical negative binomial regressions were used to examine the relationship between baseline depression and past 30-day e-cigarette use at follow-up and whether baseline stress moderated this relationship. Veterans who screened positive for depression or who endorsed higher stress levels reported greater e-cigarette use at follow-up. Stress also moderated the relationship between depression and e-cigarette use, such that regardless of stress levels, a positive depression screen was associated with greater rates of later e-cigarette use. However, for those with a negative depression screen, higher stress levels were associated with greater e-cigarette use relative to lower stress levels. Veterans with pre-pandemic depression and stress may be at highest risk for e-cigarette use. Ongoing assessment and treatment for depression and promoting stress management skills for veterans in e-cigarette use prevention and intervention programs may be valuable.

Substance Use and Mental Health Outcomes from a Text Messaging-Based Intervention for Smoking Cessation Among Young People Experiencing Homelessness.

INTRODUCTION: Cigarette smoking and associated high-risk behaviors are prevalent among youth experiencing homelessness (YEH), making appropriately tailored interventions targeting smoking behavior important for this group. We pilot tested a brief text-messaging intervention (TMI) as an adjunct to standard care for YEH who smoke and found promising preliminary effects of the intervention on smoking cessation. The purpose of the present study was to test the TMI's effect on the secondary outcomes of other substance use (including use of other tobacco/nicotine devices) and mental health symptoms. METHODS: A total of 77 participants completed the pilot randomized controlled trial, with 40 receiving the TMI (174 automated text messages plus a group smoking counseling session and provision of nicotine patches). They completed an assessment at baseline and another three months later that evaluated use of other tobacco/nicotine devices, alcohol, marijuana, and anxiety and depression symptoms. RESULTS: We found that the TMI helped to reduce secondary substance use behaviors and mental health symptoms among the participants; mainly there were medium effects of the intervention on changes in other tobacco/nicotine use, drinking, and anxiety and depression symptoms. The intervention did not have an effect on number of marijuana use days in the past month; however, past 30-day marijuana users who received the intervention benefited by reducing the number of times they used marijuana per day. CONCLUSIONS: In addition to helping reduce cigarette smoking, we found that a TMI for YEH was helpful in improving secondary outcomes, suggesting the promise of the TMI on benefiting YEH even beyond targeted smoking behavior. IMPLICATIONS: This pilot study demonstrates that by targeting cigarette smoking using a text message-based intervention among youth experiencing homelessness, effects may be seen in other areas of functioning such as other substance use and mental health.

Disposable E-Cigarette Use Prevalence, Correlates, and Associations With Previous Tobacco Product Use in Young Adults.

INTRODUCTION: Novel, inexpensive disposable e-cigarettes widely sold in attractive flavors might be exempt from US federal regulations. To inform regulatory and public health priorities, this study examined young adult disposable e-cigarette use uptake among existing tobacco users versus non-users and possible use correlates that could be potential regulatory targets. AIMS AND METHODS: Prospective cohort data were analyzed in 2021. Among baseline (2018-2019) never disposable e-cigarette users (n = 1903; mean [SD]: 19.3 [0.8] years-old), we tested prospective associations of baseline tobacco product use with follow-up (2020) disposable e-cigarette use initiation, followed by stratified analyses distinguishing baseline exclusive and dual e-cigarette/combustible tobacco use. Exploratory cross-sectional associations of tobacco-related correlate with vaping frequency among current disposable users (n = 266) were tested. RESULTS: Follow-up ever disposable e-cigarette use initiation was higher among baseline former (22.1%) and current (50.2%) versus never (6.3%) rechargeable (non-disposable) e-cigarette users. In stratified analyses, follow-up disposable e-cigarette use initiation was 0% in baseline never-vaping exclusive current smokers, higher in baseline never-vaping former smokers versus never users of any tobacco product (18.2% vs. 5.7%; adjusted odds ratio [95% CI] = 3.9 [2.1-7.5]), and higher among baseline current dual users versus never-smoking exclusive current vapers (61.3% vs. 42.2%; adjusted odds ratio [95% CI] = 3.0 [1.5-6.0]). Among follow-up current disposable e-cigarette users (overall prevalence = 10.9%), using ice-flavored (vs. fruit/sweet-flavored) e-cigarettes (adjusted rate ratio [95% CI] = 1.5 [1.0-2.1]) and vaping dependence symptoms (adjusted rate ratio [95% CI] = 2.2 [1.5-3.2]) were cross-sectionally associated with more past-month disposable e-cigarette use days. CONCLUSIONS: Young adult disposable e-cigarette use was of appreciable prevalence, including among tobacco product never users and former smokers. Regulation of disposable e-cigarettes, including ice-flavored products, might benefit young adult health. IMPLICATIONS: Sales of disposable e-cigarette products increased significantly in the United States from 2019 to 2020. These products contain high nicotine concentrations and various flavors that may appeal to young people. This study provides the first evidence that disposable e-cigarette use may be common among young adults, including among tobacco product never users and former smokers. Frequency of disposable e-cigarette use was positively associated with using ice-flavored e-cigarettes and vaping dependence. Regulatory policies and enforcement strategies addressing disposable e-cigarettes merit consideration in young adult health policy and prevention priorities.

Methamphetamine use and disordered eating: a case study of an understudied phenomenon.

PURPOSE: Little is known about co-occurring eating disorder (ED) psychopathology and methamphetamine use. Even less is known about the precise nature of how ED symptom profiles and methamphetamine use interact and influence treatment-related practices. The purpose of this study is to report a case study of a patient with co-occuring ED psychopathology and methamphetamine use. METHOD: We present the case of a White woman in her mid-30s with a long history of body image-related worries and methamphetamine use. She presented for psychiatric assessment initially for methamphetamine addiction and paranoid psychotic symptom treatment, but also reported significant weight and shape concerns. RESULTS: Over the duration of approximately 1 year of treatment, this patient experienced a reduction in her methamphetamine use, but an increased concern around how abstinence may portend weight gain. She reported that a return to methamphetamine use was underpinned by a drive to manage her weight. CONCLUSION: With increasing evidence documenting the elevated co-occurrence of methamphetamine use and ED symptomatology, this case report highlights the potential mechanisms by which these respective psychopathologies may be exacerbate the other, rendering both increased risk of relapse, and body dissatisfaction. LEVEL OF EVIDENCE: Level IV, case study.

Pilot Randomized Clinical Trial of a Text Messaging-Based Intervention for Smoking Cessation Among Young People Experiencing Homelessness.

INTRODUCTION: Smoking rates are alarmingly high among young people experiencing homelessness (YEH), yet there are no evidence-based cessation programs for this population. This paper presents results from a pilot evaluation of a text messaging-based smoking cessation treatment, as an adjunct to brief group cessation counseling, to improve abstinence rates among 18-25-year-old smokers experiencing homelessness. The goal of this study was to estimate effect sizes for a larger trial and it was not powered to detect group differences. AIMS AND METHODS: YEH smokers who had a working cell phone with them at recruitment were randomized to receive a group counseling session, nicotine patches, and written material on quitting (n = 37) or a similar program that also included a 6-week automated text messaging intervention (TMI) to provide ongoing support for quitting (n = 40). Smoking outcomes were evaluated through a 90-day follow-up. RESULTS: Seven-day point prevalence abstinence at 90-day follow-up was higher in the TMI condition than standard condition (17.50% vs. 8.11%, respectively; Cohen's h = .37); however, the 90-day continuous abstinence rate was not statistically different from zero in either condition. Reductions in the number of days smoked in the past 30 days from baseline to follow-up were greater in the TMI condition than the standard condition (-14.24 vs. -8.62, respectively; Cohen's d = .49). CONCLUSIONS: Adding a 6-week TMI support to a brief group counseling and pharmacotherapy protocol holds promise for smoking reduction and abstinence among YEH smokers. Results indicate that further development and evaluation of the TMI in this population is warranted. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03874585. Registered March 14, 2019, https://clinicaltrials.gov/ct2/show/record/NCT03874585. IMPLICATIONS: This is the first study to evaluate the feasibility of using a text messaging-based intervention (TMI) for behavior change with 18-25 year olds experiencing homelessness, and more specifically, the first to test a TMI to provide ongoing support for smoking cessation. Small to medium effect sizes for the TMI are promising in terms of implementing a TMI using participants' own cell phones, as well as the efficacy of this approach as an adjunct to standard care (brief group counseling and pharmacotherapy) for smoking cessation among YEH.
