Risk Identification in Perinatal Health Care Settings via Technology-Based Recruitment Methods: Comparative Study.

BACKGROUND: Digital screening and intervention tools have shown promise in the identification and reduction of substance use in health care settings. However, research in this area is impeded by challenges in integrating recruitment efforts into ongoing clinical workflows or staffing multiple study clinics with full-time research assistants, as well as by the underreporting of substance use. OBJECTIVE: The aim of the study is to evaluate pragmatic methods for facilitating study recruitment in health care settings by examining recruitment rates and participant characteristics using in-person-based versus flyer approaches. METHODS: This study compared recruitment rates at a Women's Health clinic in the Midwest under 2 different recruitment strategies: in person versus via a flyer with a QR code. We also examined the disclosure of substance use and risk screener positivity for the 2 strategies. We also obtained information about the current use of technology and willingness to use it for study participation. RESULTS: A greater percentage of patients recruited in person participated than those recruited via flyers (57/63, 91% vs 64/377, 17%). However, the final number recruited in each group was roughly equal (n=57 vs n=64). Additionally, participants recruited via flyers were more likely to screen positive for alcohol use risk on the Tolerance, Annoyed, Cut Down, Eye-Opener alcohol screen than those recruited at the clinic (24/64, 38% vs 11/57, 19%; χ21=4.9; P=.03). Participants recruited via flyers were also more likely to screen positive for drug use risk on the Wayne Indirect Drug Use Screener than those recruited at the clinic (20/64, 31% vs 9/57, 16%; χ21=4.0; P=.05). Furthermore, of the 121 pregnant women, 117 (96.7%) reported owning a smartphone, 111 (91.7%) had an SMS text message plan on their phone, and 94 (77.7%) reported being willing to receive SMS text messages or participate in a study if sent a link to their phone. CONCLUSIONS: The distribution of flyers with a QR code by medical staff appears to be an efficient and cost-effective method of recruitment that also facilitates disclosure while reducing the impact on clinic workflows. This method of recruitment can be useful for data collection at multiple locations and lead to larger samples across and between health systems. Participant recruitment via technology in perinatal health care appears to facilitate disclosure, particularly when participants can learn about the research and complete screening using their own device at a place and time convenient for them. Pregnant women in an urban Midwestern hospital had access to and were comfortable using technology.

Risk, Emotional Support, Child Abuse Potential, and Parenting During the First Year of the COVID-19 Pandemic.

The COVID-19 pandemic and associated mitigation efforts created stress that threatened parent and child well-being. Conditions that increase stress within families heighten the likelihood of child abuse, but social support can mitigate the impact. This short-term investigation considered whether cumulative risk, COVID-19 specific risk, and emotional support (one aspect of social support), were associated with child abuse potential during the pandemic. Additionally, we investigated whether emotional support moderated the association between COVID-19 specific risk and child abuse potential, and associations between child abuse potential and emotionally positive and emotionally negative parenting. Participants included 89 parents, from a metropolitan area with a large number of economically distressed families, who completed online questionnaires. COVID-19 specific risk and emotional support each explained additional variance in child abuse potential beyond cumulative risk, but emotional support did not moderate the association between COVID-19 specific risk and child abuse potential. Consistent with expectations, child abuse potential was negatively associated with emotionally positive parenting and positively associated with emotionally negative parenting practices. Results highlight the importance of addressing both risks and supports at multiple levels for parents during times of stress.

Participant Satisfaction with Computer-Delivered Intervention Components and Its Relation to Alcohol Outcomes.

BACKGROUND: Few computer-delivered brief intervention (CDBI) studies have evaluated participant satisfaction with individual elements of the intervention, or whether participant satisfaction impacts intervention outcomes. Purpose: This factorial trial examined whether subjective reactions to a CDBI for heavy drinking (1) varied depending on the presence versus absence of an animated narrator, a spoken voice, empathic reflections, and motivational interviewing (MI) strategies and (2) were associated with drinking outcomes at 3-month follow-up. Methods: Participants were 352 heavy drinking university students. All participants were randomly assigned to one of 16 versions of a CDBI. After finishing the CDBI, participants completed measures of intervention likability and perceived empathy. Alcohol use outcomes were assessed at 3-month follow-up. Results: CDBI characteristics had minimal effects on participant ratings of likeability and perceived empathy. However, higher likeability ratings were associated with decreases in alcohol use outcomes over the 3-month assessment period. Conclusions: Results indicate that subjective reactions to CDBIs can have important effects on alcohol use outcomes.

Testing the efficacy of motivational strategies, empathic reflections, and lifelike features in a computerized intervention for alcohol use: A factorial trial.

Although computer delivered brief interventions (CDBIs) have been effective in reducing alcohol use, few studies have examined which components of CDBIs are most associated with drinking reductions. The current factorial trial deconstructed a brief alcohol intervention into component parts to identify main and interaction effects on drinking outcomes. Participants (N = 352) were randomly assigned to 1 of 16 possible combinations of four dichotomous (present vs. absent) CDBI components for which theoretical and empirical support was available: empathic reflections, motivational strategies, a spoken voice, and an animated narrator. We measured main and interaction effects of these components on the primary outcome of self-reported mean drinks per day at 1- and 3-month follow-up, as well as on secondary outcomes, including binge drinking, intentions to reduce drinking, and alcohol consequences. Participants reduced drinking across all alcohol use indices over the 3-month assessment period. These effects were stronger for participants who were exposed to motivational strategies, F = 7.7, p < .001. Empathic reflections, use of a spoken voice, and use of an animated narrator were not associated with reductions in alcohol use, either as main effects or in interaction with other factors. Results suggest that CDBIs using motivational strategies are effective in reducing alcohol use. However, empathic reflections and lifelike characteristics (e.g., narrator, voice) may operate differently in CDBIs than they do in person-delivered interventions. More research is needed to better understand how these (or other factors) may influence efficacy. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Accuracy of five self-report screening instruments for substance use in pregnancy.

BACKGROUND AND AIMS: The accuracy of current screening instruments for identification of substance use in pregnancy is unclear, particularly given methodological shortcomings in existing research. This diagnostic accuracy study compared five existing instruments for ability to identify illicit drug, opioid and alcohol use, under privacy expectations consistent with applied practice and using a gold standard incorporating toxicological analysis. DESIGN: Prospective cross-sectional screening accuracy study. SETTING: Three sites encompassing four prenatal care clinics in the United States. PARTICIPANTS: Convenience sample of 1220 racially, ethnically and socio-economically diverse pregnant women aged 18 years and over. MEASUREMENTS: In Phase I, participants completed the five screening instruments in counterbalanced order. Instruments included the Substance Use Risk Profile-Pregnancy (SURP-P), CRAFFT (acronym for five-item screener with items related to car, relax, alone, forget, friends and trouble), 5Ps (parents, peers, partner, pregnancy, past), Wayne Indirect Drug Use Screener (WIDUS) and the National Institute on Drug Abuse (NIDA) Quick Screen. In Phase II, participants provided a urine sample and completed a calendar recall-based interview regarding substance use. These screeners were tested, using receiver operating characteristic (ROC) analysis and accuracy statistics, against a reference standard consisting of substance use in three classes (illicit drugs, opioids and alcohol), considered positive if use was evident via 30-day calendar recall or urine analysis. FINDINGS: Three hundred and fifteen of 1220 participants (26.3%) met reference standard criteria for positivity. The single-item screening questions from the NIDA Quick Screen showed high specificity (0.99) for all substances, but very poor sensitivity (0.10-0.27). The 5Ps showed high sensitivity (0.80-0.88) but low specificity (0.35-0.37). The CRAFFT, SURP-P and 5Ps had the highest area under the curve (AUC) for alcohol (0.67, 0.66 and 0.62, respectively), and the WIDUS had the highest AUC for illicit drugs and opioids (0.70 and 0.69, respectively). Performance of all instruments varied significantly with race, site and economic status. CONCLUSIONS: Of five screening instruments for substance use in pregnancy tested (Substance Use Risk Profile-Pregnancy (SURP-P), CRAFFT, 5Ps, Wayne Indirect Drug Use Screener (WIDUS) and the National Institute on Drug Abuse (Quick Screen), none showed both high sensitivity and high specificity, and area under the curve was low for nearly all measures.

Mobile Health Interventions: Exploring the Use of Common Relationship Factors.

The use of mobile health (mHealth) interventions has risen dramatically over the past two decades. It is important to consider mHealth intervention research within the broader therapy outcome literature. Among other key findings, this broader literature suggests that common relationship factors such as empathy, positive regard, and genuineness may play a critical role in therapy effectiveness. These findings raise intriguing questions for mobile interventions. For example, can mobile interventions incorporate aspects of common factors to augment their efficacy? Will the absence of relationship-based common factors make mobile interventions less effective? This viewpoint paper addresses these questions as well as related issues such as how to operationalize relationship qualities in the context of a mobile intervention and whether common relationship factors apply to computers or computerized narrators. The paper concludes by outlining a future research agenda guided by theory and empirical studies.

Feasibility and Acceptability of e-Screening and Brief Intervention and Tailored Text Messaging for Marijuana Use in Pregnancy.

Background: There are at present no evidence-based interventions for marijuana use during pregnancy, despite it being by far the most commonly used illicit drug during pregnancy. Lack of treatment-seeking, combined with implementation challenges, has limited the extent to which at-risk women receive interventions of any kind. This study sought to evaluate the feasibility and acceptability of two high-reach technology-based interventions: electronic screening and brief intervention (e-SBI) and tailored text messaging, delivered either alone or in combination. Materials and Methods: In this exploratory feasibility trial, pregnant women seeking prenatal care services and scoring positive for marijuana use risk (n = 45) were randomly assigned to e-SBI, text messaging, or e-SBI plus text messaging. We examined completion rates and acceptability ratings as a function of intervention condition and participant characteristics. Results: All participants assigned to receive the e-SBI (n = 30) were able to complete it during the in-clinic baseline session. Participants assigned to text messaging (n = 30) received a median of 24 text messages before giving birth; 6 of 30 (20%) chose to end text messages before giving birth. Acceptability ratings for the e-SBI were high, with most being above 4.4 on a 5-point scale (e.g., for ease of use, respectfulness, and helpfulness). Acceptability ratings for some aspects of the texting intervention were also high (e.g., for ease of understanding and respectfulness). Participants in the combined e-SBI plus texting condition chose to stop messages at a rate of 13.3% (2 of 15), versus 26.7% (4 of 15) in the texting-only condition (p = 0.37). Conclusions: These two high-reach intervention elements showed strong feasibility and modest to high acceptability. Future efforts evaluating efficacy are warranted, and should specifically examine the possibility that combining text messaging with a brief intervention may promote retention.

Computer-delivered indirect screening and brief intervention for drug use in the perinatal period: A randomized trial.

BACKGROUND: Under-reporting of drug use in the perinatal period is well-documented, and significantly limits the reach of proactive intervention approaches. The Wayne Indirect Drug Use Screener (WIDUS) focuses on correlates of drug use rather than use itself. This trial tested a computer-delivered, brief intervention designed for use with indirect screen-positive cases, seeking to motivate reductions in drug use without presuming its presence. METHODS: Randomized clinical trial with 500 WIDUS-positive postpartum women recruited between August 14, 2012 and November 19, 2014. Participants were randomly assigned to either a time control condition or a single-session, tailored, indirect brief intervention. The primary outcome was days of drug use over the 6-month follow-up period; secondary outcomes included urine and hair analyses results at 3- and 6-month follow-up. All outcomes were measured by blinded evaluators. RESULTS: Of the 500 participants (252 intervention and 248 control), 36.1% of participants acknowledged drug use in the 3 months prior to pregnancy, but 89% tested positive at the 6-month follow-up. Participants rated the intervention as easy to use (4.9/5) and helpful (4.4/5). Analyses revealed no between-group differences in drug use (52% in the intervention group, vs. 53% among controls; OR 1.03). Exploratory analyses also showed that intervention effects were not moderated by baseline severity, WIDUS score, or readiness to change. CONCLUSIONS: The present trial showed no evidence of efficacy for an indirect, single-session, computer-delivered, brief intervention designed as a complement to indirect screening. More direct approaches that still do not presume active drug use may be possible and appropriate.

Utility of Commercial Ethyl Glucuronide (EtG) and Ethyl Sulfate (EtS) Testing for Detection of Lighter Drinking Among Women of Childbearing Years.

OBJECTIVE: Even moderate alcohol consumption during pregnancy can pose risks to the fetus, making reliable and consistent detection of drinking in pregnancy critical. Ethyl glucuronide (EtG) and ethyl sulfate (EtS) have shown some ability to detect lower levels of drinking, but the sensitivity of commercial EtG/EtS testing to lower levels of drinking among women of childbearing age is unknown. This study sought to determine the ability of an EtG/EtS algorithm, as well as EtG alone, to detect alcohol consumption in women of childbearing age using commercial testing and cutoffs. METHOD: Ten women (ages 21-39 years of age) were administered one, two, or three standard drinks in separate sessions. Urinary EtG/EtS was measured at baseline and again at five timed intervals for 72 hours following each session. Samples from the first five participants used a commercial algorithm in which a positive test was EtG > 100 ng/ml and EtS > 25 ng/ml; samples from the next five participants were considered positive if only EtG was >100 ng/ml. RESULTS: All samples were positive at the 12-hour follow-up. By 24 hours, sensitivity for one standard drink was poor for the combined EtG/EtS assay as well as for EtG alone (20% detection) and modest for two standard drinks (40% detection). There were no positive EtG results after 36 hours. CONCLUSIONS: The EtG/EtS cutoffs used in the present study, which are representative of those used by commercial laboratories, were not sensitive enough to reliably detect light to moderate drinking beyond a 12-hour window among women of childbearing age.

Electronic Brief Intervention and Text Messaging for Marijuana Use During Pregnancy: Initial Acceptability of Patients and Providers.

BACKGROUND: Marijuana is the most widely used illicit substance during pregnancy. Technology-delivered brief interventions and text messaging have shown promise in general and pregnant samples but have not yet been applied to marijuana use in pregnancy. OBJECTIVE: The objective of the study was to evaluate, among pregnant women and prenatal care providers, the acceptability of an electronic brief intervention and text messaging plan for marijuana use in pregnancy. METHODS: Participants included patients (n=10) and medical staff (n=12) from an urban prenatal clinic. Patient-participants were recruited directly during a prenatal care visit. Those who were eligible reviewed the interventions individually and provided quantitative and qualitative feedback regarding software acceptability and helpfulness during a one-on-one interview with research staff. Provider-participants took part in focus groups in which the intervention materials were reviewed and discussed. Qualitative and focus group feedback was transcribed, coded manually, and classified by category and theme. RESULTS: Patient-participants provided high ratings for satisfaction, with mean ratings for respectfulness, interest, ease of use, and helpfulness ranging between 4.4 and 4.7 on a 5-point Likert scale. Of the 10 participants, 5 reported that they preferred working with the program versus their doctor, and 9 of 10 said the intervention made them more likely to reduce their marijuana use. Provider-participants received the program favorably, stating the information presented was both relevant and important for their patient population. CONCLUSIONS: The findings support the acceptability of electronic brief intervention and text messaging for marijuana use during pregnancy. This, combined with their ease of use and low barrier to initiation, suggests that further evaluation in a randomized trial is appropriate.

Effects of narrator empathy in a computer delivered brief intervention for alcohol use.

Computer-delivered, brief interventions (CDBIs) have been an increasingly popular way to treat alcohol use disorders; however, very few studies have examined which characteristics of CDBIs maximize intervention effectiveness. The literature has consistently demonstrated that therapist empathy is associated with reduced substance use in in-person therapy; however, it is unclear whether this principle applies to CDBIs. Therefore, the study aimed to examine whether the presence of an empathic narrator increased intentions to reduce heavy drinking in a CDBI. Results suggest that the presence of empathy increases motivation to reduce drinking, and makes participants feel more supported and less criticized.

An Ecodevelopmental Exploration of Mediators Between Maltreatment in Childhood and Drug use During Pregnancy.

Child maltreatment is associated with increased risk of substance abuse in adulthood. However, prior investigations have not examined substance use specifically in pregnancy, and have relied on self-report of substance use. The present study addresses these gaps via secondary analysis of 295 primarily low-income, Black postpartum women who agreed to complete a brief questionnaire and subsequently provided urine and hair samples. A clear relationship emerged between self-reported maltreatment and positive toxicology (with drug use present in 37.2% of maltreated participants and 17.1% of non-maltreated participants; p < .001). Depression and violence exposure were positively associated with maltreatment and with drug use. The combined effect of violence exposure and depression mediated the association between maltreatment and drug use during pregnancy (the bootstrapped 95% confidence interval of total indirect effect ranged from .17-.86). This investigation is the first to show an association between childhood maltreatment and toxicological evidence of drug use in pregnancy.

A randomised trial of a computer-delivered screening and brief intervention for postpartum alcohol use.

INTRODUCTION AND AIMS: Most women cut down or quit alcohol use during pregnancy, but return to pre-pregnancy levels of use after giving birth. Universal screening and brief intervention for alcohol use has shown promise, but has proven challenging to implement and has rarely been evaluated with postpartum women. This trial evaluated a single 20-min, electronic screening and brief intervention (e-SBI) for alcohol use among postpartum women. DESIGN AND METHODS: In this parallel group randomised trial, 123 postpartum, low-income, primarily African-American women meeting criteria for unhealthy alcohol use were randomly assigned to either a tailored e-SBI (n = 61) or a time-matched control condition (n = 62), with follow-up at 3 and 6 months. Hypotheses predicted that 7-day point-prevalence abstinence and drinking days would favour the e-SBI condition. RESULTS: No group differences were significant. Blinded follow-up evaluation revealed 7-day point prevalence of 75% for the e-SBI condition versus 82% for control at 3 months (odds ratio = 1.6) and 72% versus 73%, respectively, at 6 months. Drinking days in the past 90 and mean number of drinks per week also showed no significant differences. DISCUSSION AND CONCLUSIONS: This pilot trial failed to support a single-session e-SBI for alcohol use among postpartum women, although findings at the 3-month time point suggested that greater power might confirm transient effects of the e-SBI. As efficacy is likely to vary with e-SBI content and approach, future research should leverage technology's reproducibility and modularity to isolate key components.

Commercial Ethyl Glucuronide (EtG) and Ethyl Sulfate (EtS) Testing is Not Vulnerable to Incidental Alcohol Exposure in Pregnant Women.

BACKGROUND: Ethyl Glucoronide (EtG) and Ethyl Sulfate (EtS) have shown promise as biomarkers for alcohol and may be sensitive enough for use with pregnant women in whom even low-level alcohol use is important. However, there have been reports of over-sensitivity of EtG and EtS to incidental exposure to sources such as alcohol-based hand sanitizer. Further, few studies have evaluated these biomarkers among pregnant women, in whom the dynamics of these metabolites may differ. OBJECTIVES: This study evaluated whether commercial EtG-EtS testing was vulnerable to high levels of environmental exposure to alcohol in pregnant women. METHODS: Two separate samples of five nurses-one pregnant and the other postpartum, all of whom reported high levels of alcohol-based hand sanitizer use-provided urine samples before and 4-8 hours after rinsing with alcohol-based mouthwash and using hand sanitizer. The five pregnant nurses provided urine samples before, during, and after an 8-hour nursing shift, during which they repeatedly cleansed with alcohol-based hand sanitizer (mean 33.8 uses). The five postpartum nurses used hand sanitizer repeatedly between baseline and follow-up urine samples. RESULTS: No urine samples were positive for EtG-EtS at baseline or follow-up, despite use of mouthwash and-in the pregnant sample-heavy use of hand sanitizer (mean of 33.8 uses) throughout the 8-hour shift. CONCLUSIONS/IMPORTANCE: Current, commercially available EtG-EtS testing does not appear vulnerable to even heavy exposure to incidental sources of alcohol among pregnant and postpartum women.

Computer-Delivered Screening and Brief Intervention for Alcohol Use in Pregnancy: A Pilot Randomized Trial.

BACKGROUND: Although screening and brief intervention (SBI) for unhealthy alcohol use has demonstrated efficacy in some trials, its implementation has been limited. Technology-delivered approaches are a promising alternative, particularly during pregnancy when the importance of alcohol use is amplified. The present trial evaluated the feasibility and acceptability of an interactive, empathic, video-enhanced, and computer-delivered SBI (e-SBI) plus 3 tailored mailings, and estimated intervention effects. METHODS: We recruited 48 pregnant women who screened positive for alcohol risk at an urban prenatal care clinic. Participants were randomly assigned to the e-SBI plus mailings or to a control session on infant nutrition, and were re-evaluated during their postpartum hospitalization. The primary outcome was 90-day period prevalence abstinence as measured by timeline follow-back interview. RESULTS: Participants rated the intervention as easy to use and helpful (4.7 to 5.0 on a 5-point scale). Blinded follow-up evaluation at childbirth revealed medium-size intervention effects on 90-day period prevalence abstinence (OR = 3.4); similarly, intervention effects on a combined healthy pregnancy outcome variable (live birth, normal birthweight, and no neonatal intensive care unit stay) were also of moderate magnitude in favor of e-SBI participants (OR = 3.3). As expected in this intentionally underpowered pilot trial, these effects were nonsignificant (p = 0.19 and 0.09, respectively). CONCLUSIONS: This pilot trial demonstrated the acceptability and preliminary efficacy of e-SBI plus tailored mailings for alcohol use in pregnancy. These findings mirror the promising results of other trials using a similar approach and should be confirmed in a fully powered trial.

Acceptability of a computerized brief intervention for alcohol among abstinent but at-risk pregnant women.

BACKGROUND: Limitations in time and training have hindered widespread implementation of alcohol-based interventions in prenatal clinics. Also, despite the possibility of underreporting or relapse, many at-risk women report that they quit drinking after pregnancy confirmation so that interventions focusing on current drinking may seem unnecessary. The Computerized Brief Intervention for Alcohol Use in Pregnancy (C-BIAP) was designed to (a) be implemented via a handheld device in prenatal clinics, and (b) use a modified brief intervention strategy with women who screen at-risk but report no current drinking. METHODS: The authors administered the C-BIAP to 18 T-ACE (Tolerance, Annoyance, Cut Down, and Eye Opener)-positive pregnant African American women who provided quantitative and qualitative feedback. RESULTS: The C-BIAP received high ratings of acceptability; qualitative feedback was also positive overall and suggested good acceptance of abstinence themes. CONCLUSIONS: Technology may be a feasible and acceptable method for brief intervention delivery with pregnant women who do not report current drinking.

A randomized study of the effect of anonymity, quasi-anonymity, and Certificates of Confidentiality on postpartum women's disclosure of sensitive information.

BACKGROUND: Under-reporting of substance use and other sensitive information is a substantial threat to internal study validity, particularly during the perinatal period. Anonymous approaches are associated with greater disclosure but are incompatible with longitudinal follow-up. Alternative approaches include use of a U.S. Federal Certificate of Confidentiality (CoC) and quasi-anonymous methods, in which there is no link between name and data. However, the relative effect of these procedures on disclosure is unknown. This randomized study was designed to evaluate the effects of consent condition (anonymous, quasi-anonymous, CoC, and traditional confidentiality) on disclosure of sensitive information among postpartum women. METHODS: Participants were 200 postpartum, primarily African-American women who were randomly assigned to one of the four consent conditions and completed a brief computer-delivered assessment of alcohol and drug use, sexual risk, intimate partner violence, and emotional distress. RESULTS: Participants in the anonymous and quasi-anonymous conditions disclosed significantly more sensitive information than those in the traditional consent condition. In contrast, no advantage in overall disclosure was observed for the CoC condition. This result was largely consistent across specific content areas with the exception of emotional distress, disclosure of which was unrelated to consent condition. CONCLUSIONS: Although use of a CoC has limited impact on disclosure, the quasi-anonymous method may increase disclosure to a similar extent as full anonymity. Quasi-anonymous approaches should be considered when under-reporting is likely, a context in which the disadvantages of this approach must be balanced against its advantages.

Computer-delivered screening and brief intervention (e-SBI) for postpartum drug use: a randomized trial.

Electronic screening and brief intervention (e-SBI) approaches for substance use have shown early promise. This trial was designed to replicate previous findings from a single 20-minute e-SBI for drug use among postpartum women. A total of 143 postpartum, primarily low-income African-American women meeting criteria for drug use, were randomly assigned to either a tailored e-SBI or a time-matched control condition. Blinded follow-up evaluation 3- and 6-months following childbirth revealed strong effects for confirmed illicit drug use abstinence at the 3-month observation (OR=3.3, p=.01), as did hair analysis at 6months (OR=4.8, p=.018). Additional primary outcomes suggested small to moderate effect sizes in favor of the e-SBI, but did not reach significance. This result replicates previous findings but fails to show durable effects. Assessment reactivity, e-SBI design, and possible extension of e-SBI via tailored messaging all merit careful consideration.

Prevalence and Perceived Financial Costs of Marijuana versus Tobacco use among Urban Low-Income Pregnant Women.

OBJECTIVE: To examine the relative prevalence of marijuana and tobacco use among low-income post-partum women, using self-report, urine, and hair testing data; and to further explore perceptions of the substances among postpartum women by evaluating perceived risk and monetary cost of prenatal marijuana versus tobacco use. METHODS: Data from two studies were available for a total of 100 (Study 1) and 50 (Study 2) low-income, primarily African-American post-partum women. Study 1 participants completed brief self-report measures of substance use as well as urine and hair samples; study 2 participants completed a brief opinion survey regarding the risks and monetary costs of prenatal marijuana use. RESULTS: In Study 1, the self-reported prevalence of any tobacco or marijuana use in the past three months was 17% and 11%, respectively. However, objectively-defined marijuana use was more prevalent than self-reported tobacco use: 14% tested positive for marijuana by urinalysis, and 28% by hair analysis. Study 2 participants were more likely to believe that there is a safe level of marijuana use during pregnancy, and nearly half believed that using marijuana during pregnancy was less expensive than smoking cigarettes. CONCLUSION: Marijuana use may be as or more prevalent than tobacco use among low-income, African-American pregnant women. These findings may in part be attributable to perceptions of roughly equivalent cost and the lack of a clear public health message regarding prenatal marijuana use, combined with growing pro-marijuana advocacy. A broader public health response to address prenatal marijuana use, along with other substances of abuse, is needed.

A randomized trial of the effects of anonymity and quasi anonymity on disclosure of child maltreatment-related outcomes among postpartum women.

Anonymity may facilitate disclosure of maltreatment-related variables among parents, particularly in the perinatal period. This study was conducted in order to (a) confirm the effect of anonymity on commonly used measures in the field of child maltreatment; (b) examine the extent to which quasi anonymity (in which identifying information is collected but not linked to research data) can also facilitate disclosure on maltreatment-related measures; and (c) examine potential explanatory mechanisms of any association between level of anonymity and disclosure. This study further sought to evaluate these associations in the perinatal period, a crucial point for intervention that is also a time when rates of disclosure may be particularly low. A total of 150 postpartum, primarily African American women were randomly assigned to conditions involving traditional confidentiality, quasi anonymity, or full anonymity. Overall, disclosure on maltreatment-related measures was more than twice as likely for participants in the anonymous condition; quasi anonymity resulted in similar but somewhat smaller increases in disclosure. Anonymous methods may be greatly underutilized in child maltreatment research, and quasianonymous methods show promise as an alternative for longitudinal designs.
