RESUMEN

STATEMENT OF THE PROBLEM: Hispanic American adolescents experience high rates of pregnancy with profound consequences. Compared with White teens, Hispanic teens use contraception less frequently and often choose less effective forms of contraception. Access to contraception is a primary barrier to use which contributes to relatively high and disparate rates of pregnancy in Hispanic teens. This integrative review identifies facilitators and barriers of contraception access and use for Hispanic women, 13-17 years of age, living in the U.S. METHODOLOGY: Following the Whittemore and Knafl (2005) methodology and PRISMA guidelines, peer reviewed studies were retrieved from PUBMED, CINAHL and EMBASE. The Mixed Methods Appraisal Tool was used to assess the study quality and thematic analysis was used to categorize barriers and facilitators. FINDINGS: Of 131 studies retrieved, 16 met inclusion criteria. Individual, interpersonal and healthcare provider factors were identified as primary categories of barriers and facilitators with structural issues comprising an additional barrier category. Individual level barriers were disproportionately represented and further categorized into themes: beliefs/misconceptions, dislike of contraception, pregnancy risk perception, lack of knowledge, and lack of control. Barriers related to cultural and religious influences were identified in individual, interpersonal and structural levels. The most frequently reported facilitators were perceived parent comfort discussing sexual health and past experience of pregnancy. DISCUSSION: Limitations in this review may stem from heterogeneity in the acculturation and geography of participants and analysis by a single reviewer. Implications include considering the range of information sources and the influence they have on risk perception and risk mitigation for this population. CONCLUSION & SIGNIFICANCE: Adolescents describe many modifiable influences on contraception access and use. Misperceptions related to contraception, stemming from beliefs and perceptions, can be corrected through increased access to reliable sources of sex education, parental support, and direct access to nurses and healthcare providers. Awareness of these influences can inform further research and intervention development to address these health disparities.

RESUMEN

Kumpfer's resilience framework (KRF) was initially developed from evidence on resilience and its predictors among at-risk youth. This framework has been expanded to guide resilience research in diverse populations facing a variety of stressors. However, KRF's strengths and weaknesses have not been evaluated since its publication. Guided by Walker and Avant's method, an analysis of KRF was conducted drawn from 41 publications. A revised KRF diagram was proposed on the basis of the analysis to improve clarity, consistency, logical structure, and parsimony in the diagram of KRF. Overall, KRF provides a useful, generalizable, and testable theoretical framework for future resilience research.

RESUMEN

Health care organizations have struggled to establish par levels of risk management personnel needed to effectively accomplish risk management functions. This study set out to determine whether a par level staffing model could be established utilizing a nonclinical role to enable the clinical risk manager to focus on key risk management core functions, therefore enhancing risk management department efficacy. Utilizing a model published by Howard and Felton, Trinity Health Insurance and Risk Management Services (IRMS) evaluated risk management staffing according to our core functions and workload and determined recommended risk management staffing levels for our organization. Eighteen Risk Managers from 13 acute care hospitals participated in a 2-week time study documenting time spent and estimated time needed to complete core risk management functions. By quantifying the time needed to complete risk management core functions and evaluating which activity could best be completed by specific roles, we have established both a recommended baseline staffing level of one risk manager FTE per 6650 monthly average adjusted patient days (APD), as well as a work distribution model of 70% clinical and 30% nonclinical split of risk management FTEs for our hospitals. Organizations can similarly evaluate their staffing according to their core functions and workload.

RESUMEN

The way consumers get and seek health information reflects the current information landscape. To gather updated insights on consumer experiences with and attitudes towards direct-to-consumer (DTC) promotion of prescription drugs, we conducted a nationally representative survey of 1,744 US adults using a mail-push-to-web methodology with paper nonresponse follow-up. Results showed high exposure and indifferent attitudes to DTC promotion. Respondents reported DTC promotion has prompted action, particularly searches for more information, increased use of online resources, and some reported that they refused to take or stopped taking a prescription drug because they saw or heard about the drug's side effects.

RESUMEN

BACKGROUND: Current treatments for recurrent glioblastoma offer limited benefit. The authors report the antitumor activity and safety of the anti-programmed death 1 (anti-PD-1) immunotherapy, pembrolizumab, in programmed death ligand 1 (PD-L1)-positive, recurrent glioblastoma. METHODS: Adult patients with PD-L1-positive tumors were enrolled in the recurrent glioblastoma cohort of the multicohort, phase 1b KEYNOTE-028 study (ClinicalTrials.gov identifier, NCT02054806) and received pembrolizumab 10 mg/kg every 2 weeks for up to 2 years. The primary endpoint was investigator-assessed overall response rate according to the Response Evaluation Criteria in Solid Tumors, version 1.1. Archival tumor samples were assessed for PD-L1 expression levels (prospectively) and T-cell-inflamed gene expression profile score (retrospectively). RESULTS: After a median follow-up of 14 months (range, 2-55 months) among the 26 enrolled patients, the overall response rate was 8% (95% CI, 1%-26%). Two partial responses, lasting 8.3 and 22.8 months, occurred. Progression-free survival (median, 2.8 months; 95% CI, 1.9-8.1 months) rate at 6 months was 37.7%, and the overall survival (median, 13.1 months; 95% CI, 8.0-26.6 months) rate at 12 months was 58%. Correlation of therapeutic benefit to level of PD-L1 expression, gene expression profile score, or baseline steroid use could not be established. Treatment-related adverse events occurred in 19 patients (73%), and 5 patients experienced grade 3 or 4 events (there were no grade 5 events). Immune-mediated adverse events and infusion reactions occurred in 7 patients (27%). CONCLUSIONS: Pembrolizumab monotherapy demonstrated durable antitumor activity in a subset of patients with manageable toxicity in this small, signal-finding, recurrent glioblastoma cohort. Future studies evaluating rationally designed pembrolizumab combination regimens may improve outcomes in patients with recurrent glioblastoma.

RESUMEN

This paper seeks to open a dialogue concerning the current trend in hiring non-nurse faculty (NNF) to tenure track positions in schools/colleges of nursing. The evolution of non-nurses as faculty, including a review of contemporary papers in affecting this trend, is offered. Three means of involving non-nurses in advancing our discipline are presented. The impact of the growing trend of NNF is discussed relative to the integrity of our discipline and effects on education. We conclude by suggesting a manner of proceeding and raise questions for furthering dialogue.

RESUMEN

Objective: To describe chemotherapy treatments, associated health care use and costs, and survival for women diagnosed with cervical cancer in the United States.Methods: This was a retrospective cohort study of patients aged ≥65 years, identified in linked Surveillance, Epidemiology, and End Results (SEER) and Medicare databases. Women with a new primary diagnosis of cervical cancer between January 2007 and December 2013 were followed until December 2014. Systemic chemotherapy treatments, health care visits and costs (2016 USD rates), and survival were determined by the line of therapy.Results: Of 1651 women in the analysis, 810 (49.1%) were diagnosed at stages I or II, 411 (24.9%) at stage III, and 430 (26.0%) at stage IV. A total of 225 (13.6%) women received first-line (1L) systemic chemotherapy. Of those who received 1L chemotherapy, 73 (32.4%) received second-line (2L) chemotherapy, and 29 (12.9%) received third-line (3L) chemotherapy. During 1L and 2L chemotherapies, patients averaged 5.9 and 6.5 health care visits per month, respectively, and incurred total mean health care costs per patient per month of $7098 and $8770, respectively. Median survival from the start of 1L and 2L chemotherapy was 14.0 and 10.4 months, respectively.Conclusion: Elderly patients with advanced cervical cancer had a poor prognosis, with a median survival of 14 months or less, and had no standard of care for 2L therapy. Systemic chemotherapies pose a substantial economic burden in the range of $7000 to $9000 per patient per month. These results highlight the high unmet medical need among elderly patients with cervical cancer.

RESUMEN

BACKGROUND: Despite a protracted disease course and multiple available therapies, patients with well-differentiated neuroendocrine tumors (NETs) inevitably experience disease progression. Programmed death-ligand 1 (PD-L1) has been associated with NET progression and prognosis. The multicohort, phase 1 KEYNOTE-028 study (ClinicalTrials.gov identifier NCT02054806) evaluated the activity and safety of the anti-programmed cell death protein 1 immunotherapy pembrolizumab in patients with well-differentiated or moderately-differentiated NETs. METHODS: Patients with PD-L1-positive, locally advanced or metastatic carcinoid or well-differentiated or moderately-differentiated pancreatic NETs (pNETs) were enrolled into separate cohorts and received pembrolizumab at a dose of 10 mg/kg every 2 weeks for up to 2 years. The objective response rate was the primary endpoint (as per Response Evaluation Criteria in Solid Tumors version 1.1, by investigator review). Safety was a secondary endpoint. RESULTS: Of 170 and 106 patients, respectively, who had evaluable samples among those screened for the carcinoid and pNET cohorts, 21% and 25%, respectively, had PD-L1-positive tumors; of these, 25 and 16 patients, respectively, were eligible and treated. The median follow-up was 20 months (range, 2-35 months) and 21 months (range, 5-32 months), respectively. The objective response rate was 12.0% (95% CI, 2.5%-31.2%) and 6.3% (95% CI, 0.2%-30.2%), respectively; 3 partial responses occurred among the carcinoid cohort and 1 among the pNET cohort. The median duration of response in the carcinoid cohort was 9.2 months (range, 6.9-11.1 months), and was not reached in the pNET cohort. No complete responses occurred. Treatment-related adverse events occurred in 68% and 69% of patients, respectively, most often diarrhea (7 patients in the carcinoid cohort and 4 patients in the pNET cohort) and fatigue (6 patients in each cohort). Hypothyroidism was the most common immune-mediated adverse event (5 patients in the carcinoid cohort and 2 patients in the pNET cohort). CONCLUSIONS: Pembrolizumab demonstrated antitumor activity in a subset of patients with NETs and was well-tolerated.

RESUMEN

BACKGROUND: Direct-to-consumer prescription drug advertising is prevalent and affects patient care. Previous research that examined its effect on the patient-provider relationship predates many changes in the advertising and medical landscape that have occurred in the last decade, such as the rise in online promotion and the push for value-based medicine. METHODS: We conducted a nationally representative mail-push-to-web survey of 1744 US adults in 2017 to explore how patients view the effects of direct-to-consumer prescription drug advertising on patient-provider interactions. RESULTS: Most respondents (76%) said they were likely to ask a health care provider about advertised drugs; 26% said they had already done so. Among the 26% of respondents who talked to a health care provider about a specific prescription drug they saw advertised, 16% said they received a prescription for the advertised drug. Few respondents (5%) reported that advertising had caused conflict with a health care provider, 16% said it had caused them to question their provider's advice, and 23% said they were likely to look for a different provider if their provider refused to prescribe a requested brand name drug. DISCUSSION: These results suggest that direct-to-consumer advertising is driving some patients to discuss specific products with their health care providers but that most patients do not believe advertising has a negative influence on the patient-provider interaction itself.

RESUMEN

PURPOSE: The objective of this study was to empirically test a theoretical model to determine the cognitive mechanisms that are associated with adolescent alcohol use and alcohol problems. We posited that alcohol outcome expectancies would affect alcohol-refusal self-efficacy through the drinker self-schema. We also posited that alcohol outcome expectancies and the drinker self-schema would affect alcohol use and problems through alcohol-refusal self-efficacy. METHODS: A survey was administered to 225 adolescents in a public junior high school in Taiwan at two-time points, six months apart. Path analysis was used to determine the mechanisms underlying the alcohol-related cognitive constructs on the alcohol use and alcohol problems separately, controlling for appropriate alcohol-related personal and environmental factors. Indirect effects were estimated using the bootstrapping method. RESULTS: Higher positive alcohol outcome expectancies and lower negative alcohol outcome expectancies predicted higher drinker self-schema scores. Higher positive alcohol outcome expectancies and drinker self-schema scores predicted lower alcohol-refusal self-efficacy. Lower alcohol-refusal self-efficacy was associated with a history of drinking and alcohol problems in the past six months. Effects of alcohol outcome expectancies on alcohol use and alcohol problems were partially mediated through the drinker self-schema and alcohol-refusal self-efficacy. CONCLUSIONS: Findings support the proposed theoretical cognitive mechanisms underlying alcohol use and alcohol problems in a sample of Taiwanese adolescents. Given that alcohol-related cognitive constructs are modifiable, the findings also provide a foundation to suggest that interventions to reduce positive alcohol outcome expectations and prevent the formation of a drinker self-schema may facilitate alcohol-refusal self-efficacy and mitigate drinking behaviors in this adolescent population.

RESUMEN

Interim results from the two-cohort, phase 2 KEYNOTE-100 study (NCT02674061) of 376 patients with previously treated advanced recurrent ovarian cancer (ROC) showed that pembrolizumab monotherapy was associated with an objective response rate (ORR) of 8.0% (95% CI, 5.4-11.2). We present outcomes for the Japanese patients (n = 21) enrolled in KEYNOTE-100. Patients with epithelial ROC had received either 1-3 prior chemotherapy lines and had platinum-free interval or treatment-free interval (PFI; TFI) of 3-12 months (cohort A) or 4-6 prior chemotherapy lines and had PFI/TFI of ≥3 months (cohort B). All patients received pembrolizumab 200 mg every 3 weeks as monotherapy for 2 years or until progression, death, unacceptable toxicity or consent withdrawal. Primary objectives were ORR per RECIST v1.1 for each cohort and higher programmed death ligand-1 (PD-L1) tumor expression. The relationship between PD-L1 expression (measured as combined positive score [CPS]) and ORR was assessed. Twenty-one Japanese patients (cohort A, n = 19; cohort B, n = 2) were treated. The median (range) age was 57 (37-78) years; 19 (90.5%) patients had ECOG status of 0 and 16 (76.2%) patients had stage III-IV disease. ORR was 19.0% (95% CI, 5.4-41.9) and seemed to increase with increasing PD-L1 expression. A total of 13 (61.9%) patients had treatment-related adverse events (TRAE), and 5 (23.8%) had grade 3-4 TRAE. There were no treatment-related deaths in this subpopulation. Pembrolizumab monotherapy was associated with antitumor activity in Japanese patients with ROC, with no new safety signals identified in this subpopulation. The data suggested a trend toward higher PD-L1 expression among some patients with higher ORR.

RESUMEN

PURPOSE: Misperceptions of how the US Food and Drug Administration (FDA) regulates prescription drugs may affect how consumers assess the safety and efficacy of prescription drugs. The study objective was to survey the public on their knowledge of FDA oversight regarding prescription drug approval and advertising. METHODS: In 2017, we conducted a nationally representative mail-push-to-web survey with 1,744 US adults. RESULTS: Although most respondents (86%) knew that FDA approves prescription drugs, we found misperceptions about what that approval means. In addition, few respondents understood FDA oversight of prescription drug advertising, with approximately half of respondents reporting that they did not know whether FDA approved these ads or components of the ads, and several mis-reporting that FDA approves these ads (31%) or components of the ads (22%-41%). CONCLUSIONS: Enhanced collaboration and communication with the public by key stakeholders in this space could increase public understanding of the roles and responsibilities of FDA.

RESUMEN

Disordered eating behaviors are prevalent in Mexican-American college-enrolled women and contribute to compromised physical and psychological health. Although disordered eating behaviors are multi-determined, few studies have examined individual difference factors that contribute to disordered eating behaviors in Mexican women beyond acculturation. Evidence suggests that individual differences in the constellation of identities may be an important factor influencing the disordered eating behaviors. We hypothesized that individual differences in the collection of identities (self-schemas) increases susceptibility to defining oneself as fat (fat self-schema) and contribute to disordered eating behaviors over time in Mexican American college women. A 12-month longitudinal design was used to measure the level of disordered eating behaviors at 5 points over 12 months in 477 Mexican American women. Identity properties (i.e., positive self-schemas, negative self-schemas, fat self-schema) were measured at baseline. Controlling for relevant covariates, latent growth curve models showed that Mexican American women with few positive and many negative self-schemas were more likely to define themselves as fat, which in turn, predicted purging and fasting/restricting behaviors across the year. However, identity properties were not predictive of binge eating and excessive exercise episodes. Interventions focused on development of positive self-schemas that reflect areas of interest and competence and the revision of negative self-schemas may protect against purging and fasting/restricting in Mexican American college-enrolled women.

RESUMEN

Unhealthy eating and weight control behaviors are important but modifiable factors that contribute to obesity in majority and minority populations. Studies suggest that these behaviors are common in Mexican American women, but most studies completed to date have focused on college enrolled Mexican American women. Little is known about body weight concerns, eating and weight control behaviors in low acculturated immigrant Mexican women. This qualitative descriptive study utilized two focus groups with 15 women to identify and describe body weight and shape perceptions, and thoughts and behaviors related to eating and weight control of low acculturated Mexican American living in disadvantaged economic situations. Conventional content analysis was used to analyze data and three main themes were identified: (1) body weight values and concerns, (2) eating and food, and (3) weight loss strategies and consequences. The first two themes shared five subthemes including emotion, health, age, family, and culture. Results suggest Mexican American women experience weight concerns that are in conflict with food/eating values and experiences. This conflict is influenced by cultural, family, and inter/intrapersonal factors and contributes to unhealthy eating and weight control behavior. The transition and assimilation to the United States is complex and dynamic. Thus understanding how the conflict regarding body weight and food influence Mexican American women's health behaviors is important and provides valuable knowledge essential to guide further research and intervention development.

RESUMEN

PURPOSE: Biomarkers that can predict response to anti-programmed cell death 1 (PD-1) therapy across multiple tumor types include a T-cell-inflamed gene-expression profile (GEP), programmed death ligand 1 (PD-L1) expression, and tumor mutational burden (TMB). Associations between these biomarkers and the clinical efficacy of pembrolizumab were evaluated in a clinical trial that encompassed 20 cohorts of patients with advanced solid tumors. METHODS: KEYNOTE-028 ( ClinicalTrials.gov identifier: NCT02054806) is a nonrandomized, phase Ib trial that enrolled 475 patients with PD-L1-positive advanced solid tumors who were treated with pembrolizumab 10 mg/kg every 2 weeks for 2 years or until confirmed disease progression or unacceptable toxicity occurred. The primary end point was objective response rate (ORR; by RECIST v1.1, investigator review). Secondary end points included safety, progression-free survival (PFS), and overall survival (OS). Relationships between T-cell-inflamed GEP, PD-L1 expression, and TMB and antitumor activity were exploratory end points. RESULTS: ORRs (with 95% CIs) ranged from 0% (0.0% to 14.2%) in pancreatic cancer to 33% (15.6% to 55.3%) in small-cell lung cancer. Across cohorts, median (95% CI) PFS ranged from 1.7 months (1.5 to 2.9 months) to 6.8 months (1.9 to 14.1 months) in pancreatic and thyroid cancers, respectively, and median OS from 3.9 months (2.8 to 5.5 months) to 21.1 months (9.1 to 22.4 months) in vulvar and carcinoid tumors, respectively. Higher response rates and longer PFS were demonstrated in tumors with higher T-cell-inflamed GEP, PD-L1 expression, and/or TMB. Correlations of TMB with GEP and PD-L1 were low. Response patterns indicate that patients with tumors that had high levels of both TMB and inflammatory markers (GEP or PD-L1) represent a population with the highest likelihood of response. Safety was similar and consistent with prior pembrolizumab reports. CONCLUSION: A T-cell--inflamed GEP, PD-L1 expression, and TMB predicted response to pembrolizumab in multiple tumor types. These biomarkers (alone/in combination) may help identify patients who have a higher likelihood of response to anti-PD-1 therapies across a broad spectrum of cancers.

RESUMEN

Black and Hispanic populations perceive their skin cancer risk to be low and are less likely to use sun protection strategies. We conducted formative research to understand knowledge, awareness, beliefs, and behaviors among these groups. In 2017, eighteen focus groups were conducted with black and Hispanic respondents(18-44 years) in four US cities. Groups were segmented by participant characteristics associated with elevated or lower risk for skin cancer, by race/ethnicity, gender, and age. A professional moderator followed a semi-structured discussion guide, and focus group transcripts were analyzed using conventional content analysis and NVIVO 11 Software. Most participants perceived themselves to be at low skin cancer risk due to their "darker skin tone" and/or "lack of family history." Skin cancer signs and symptoms were more inconsistently reported by blacks than Hispanics. Few participants reported regular sun protection behaviors. Those who did used sunscreen, wore protective clothing, and had elevated risk based on sun sensitivity or UV exposure. While most participants recalled family discussions (as youth) about sunscreen and sun protection, the understood intent was to warn against "further skin darkening" or to "prevent aging," not to reduce sun burns or skin cancer risk. Tanning bed use was low across all segments, especially among black respondents. Tailored skin cancer prevention campaigns need to address misperceptions about risks and benefits of skin cancer prevention behaviors among black and Hispanic populations. Families, peer groups, and healthcare providers need to be engaged in the creation of educational interventions and messaging efforts that target these populations.

RESUMEN

OBJECTIVES: To assess an intervention derived from self-regulation theory (SRT) to promote well-being for individuals with advanced lung cancer. SAMPLE & SETTING: 45 adults with advanced lung cancer who were receiving chemotherapy at an ambulatory cancer center. METHODS & VARIABLES: Participants were randomized to the intervention group or usual care control group. Feasibility assessment focused on recruitment, retention, design, methods, and fidelity. Outcome measures of quality of life, symptoms, and distress were collected at four time points. The main research variables were symptoms, quality of life, and distress. RESULTS: The participation rate was 79%, and the retention rate was 62%. Participant loss was most often because of progressive disease and occurred early in the study. High fidelity was noted for delivery of the intervention as planned and outcome data collection by telephone. The mean number of interventions delivered was 5.5 of a planned 8. A high level of acceptability was reported for participants completing the intervention. IMPLICATIONS FOR NURSING: Although delivering the SRT-derived intervention with fidelity was possible, feasibility findings do not warrant intervention replication in this population.

RESUMEN

BACKGROUND: Previous studies have reported conflicting results on the relationship between androgen deprivation therapy (ADT) and the risk of depression. We assessed whether ADT is associated with depression in a unique data set of men with recurrent prostate cancer. PATIENTS AND METHODS: We studied a cohort of 656 men in the prospective COMPARE (Comprehensive, Multicenter, Prostate Adenocarcinoma) registry who experienced biochemical recurrence after radiation therapy (RT) only, radical prostatectomy (RP) with or without RT, or ADT with RP or RT. Multivariable logistic regression was used to determine the relationship between the modality of treatment and patient-reported depression. RESULTS: Of 656 men, 44 (6.7%) experienced depression. The prevalence of depression stratified by treatment was 3.2% for RT only, 5.9% for RP with or without RT, and 9.1% for ADT plus RP or RT. Compared with RT-only, ADT plus RP or RT was associated with a significantly increased rate of depression (P = .031) and RP with or without RT was not (P = .195). On multivariate analysis adjusting for age and baseline comorbidities, the receipt of ADT was associated with an increased risk of depression (odds ratio, 3.29; 95% confidence interval, 1.11-9.76; P = .032) compared with RT only. No statistically significant difference was found in the risk of depression for men who received RP with or without RT versus RT only (odds ratio, 2.12; 95% confidence interval, 0.68-6.65; P = .19). CONCLUSION: Men with recurrent prostate cancer who underwent ADT were 3 times more likely to report experiencing depression. Treating physicians should discuss depression as a possible side effect when considering the use of ADT and should screen for depression in men who have received ADT.

RESUMEN

BACKGROUND: Drinking and smoking commonly co-occur in undergraduate students. Although an identity as a drinker is a known predictor of alcohol use and alcohol problems, and early evidence suggests that it also predicts smoking, the role of these behaviors in the development of an identity as a drinker is unknown. In this study, the authors conceptualized a drinker identity as an enduring memory structure referred to as a self-schema and conducted a preliminary investigation of the relationships between early drinking experiences, drinker self-schema, and alcohol and tobacco use in undergraduate students. METHODS: Three-hundred thirty undergraduates who reported current alcohol and tobacco use were recruited for an online survey study. Frequency of alcohol and tobacco use in the past 30 days, drinker self-schema, and early experiences with alcohol were measured. RESULTS: Structural equation modeling showed that parental alcohol problems were associated with early onset of drinking. Early onset of drinking and high school friends' drinking were associated with more alcohol use and alcohol-related problems in high school. Alcohol problems during high school were associated with high drinker self-schema scores, which were associated with high frequency of alcohol and tobacco use during college. The indirect effects through the drinker self-schema were significant. CONCLUSIONS: Although cross-sectional, this preliminary examination supports theoretical predictions that early alcohol experiences may contribute to development of the drinker self-schema, which, as expected, was positively associated with alcohol and tobacco use in college. Longitudinal studies that track the unfolding of drinking behavior and the contextual factors that are associated with it in the development of the drinker self-schema are essential to confirming the theoretical model. If supported, implications for intervention at different developmental stages to prevent early onset of drinking, limit adolescent alcohol use, and modify the development of a drinker self-schema may mitigate undergraduate drinking and smoking.
