Objective: In June 2022, the U.S. Supreme Court removed federal abortion protections, giving individual states the authority to enact abortion regulations. Since that ruling, many states have enacted abortion bans; however, several of these states allow "rape exceptions," theoretically providing rape victims who become pregnant access to abortion services. Notably, alcohol use by the rape victim and perpetrator is common. In this brief report, we describe findings from research on alcohol-involved rape that have the potential to impact the utility of rape exceptions.

Method: In this synthesis of the research literature pertaining to alcohol-involved rape victimization and perpetration, we focus on key concepts detailed in extant research likely relevant to accessing abortion services through rape exceptions.

Results: Victim alcohol intoxication may limit the use of rape exceptions to abortion bans by delaying rape acknowledgment, increasing victim blame, undermining victim credibility, and deterring rape reporting. Commensurately, perpetrator alcohol intoxication may increase the need for victims to access abortion services by reducing perpetrator condom use during rape and increasing other sexually aggressive acts such as nonconsensual condom removal.

Conclusions: Research evidence suggests that alcohol-involved rape incidents present critical obstacles to utilizing statutory rape exceptions to banned abortion services beyond challenges that non-alcohol-involved rape survivors are also likely to experience. Rape survivors from oppressed communities (e.g., people of color, gender minorities, and/or sexual minorities) may be disproportionately impacted. Empirical investigations specifically examining how substance use during rape impacts reproductive health care accessibility are paramount for informing health care providers, law enforcement, legal practitioners, and policymakers.

Objective: Medications for opioid use disorder (OUD or MOUD) treatment combining pharmacotherapy with psychosocial support are effective for managing OUD. However, treatment engagement remains a challenge, with retention rates ∼30%-50%. Although social connection has been identified as important to recovery, it remains unclear whether and how social factors can bolster participation in treatment.

Method: Individuals receiving MOUD at three outpatient treatment programs (N = 82) and healthy community controls (N = 62) completed validated measures assessing social connection including (a) size, diversity, and embeddedness of social networks; (b) perceived social support and criticism within familial relationships; and (c) subjective social status. For those receiving MOUD, we also examined how aspects of social connection related to opioid (re)use and treatment engagement (medication adherence, group, and individual meeting attendance) assessed over ∼8 weeks/person.

Results: Compared to controls, individuals receiving MOUD had smaller and less diverse and embedded social networks (Cohen's d > 0.4), and despite similar levels of perceived social support (d = 0.02), reported higher levels of social criticism (d = 0.6) and lower subjective social status (d = 0.5). Within the MOUD group, higher social network indices correlated specifically with higher therapeutic group attendance (Rs > 0.30), but not medication adherence, while higher levels of perceived criticism correlated with more frequent opioid use (R = 0.23). Results were mostly robust to control for sociodemographic variables, psychological distress/COVID-19, and treatment duration, but differed by MOUD type/program.

Conclusions: These findings highlight the potential importance of assessing an individual's social capital, promoting positive social connection, and continuing to assess the implementation and value of psychosocial support in MOUD treatment.

Objective: The main reasons women in the general population seek abortion are financial, timing, and partner-related reasons. While women with opioid use disorder (OUD) appear to use abortion services more than women in the general population, reasons for abortion in this group have not been examined to our knowledge.

Method: Female patients aged 18-50 years in OUD treatment at 22 randomly selected facilities in Michigan were surveyed. The survey included items assessing reproductive health history. Women who reported having one or more abortions were asked to think back to that time and their reasons for choosing abortion. Twenty potential reasons and a write-in option were offered; women could endorse as many as applied.

Results: Of 260 women surveyed, 84 reported having an abortion. Of these, most (77.4%) reported multiple reasons for having an abortion. The most common reasons for having an abortion were not having money to take care of a baby (54.8%), feeling too young to have a child and not feeling ready to be a mother (both 42.9%), not loving the father and other partner-related concerns (25.0%-32.1%), and having concerns about the effects of their drug use (28.6%). No combination of reasons for abortion emerged as more prevalent than any other.

Conclusions: Like women in the general population, women in treatment for OUD had not only abortions because of financial, timing, and partner-related reasons but also concerns about the effects of their drug use. These results underscore the multiple and often interrelated reasons that lead women to seek abortion. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Predicting which young people are likely to use tobacco in the future is critical for prevention and intervention. Although measures for assessing susceptibility to using tobacco have fulfilled this goal for decades, there is almost no standard for the number of items that should be administered, or which items should be administered for which products. This study explored whether brief but psychometrically sound versions of commonly used susceptibility measures can adequately capture the construct relative to longer measures.

Method: A sample of young people (N = 451; M_age = 16.5 years; 64% females; 65% White) completed 33 susceptibility items, which are designed to assess susceptibility to use different types of tobacco products (cigarette, smokeless tobacco, vaping products, and little cigars/cigarillos) of various flavors (tobacco, menthol, and sweet).

Results: Analysis of these 33 items indicated that asking about the likelihood of using each tobacco product class when a best friend offers it (four items in all) captures 98.5% of information that is captured using the longer set of items; asking the best friend question for each product by each flavor category (11 items in all) captures 99.7% of the information.

Conclusions: Depending on research needs, tobacco use susceptibility can be measured with little loss of information by administering a limited set of items assessing the likelihood that a young person will use a tobacco product if a friend offers it for any product-flavor combination.

Objective: Past research has highlighted that sexual minority youth (SMY) are at particular risk for heightened substance use compared to their heterosexual peers; however, few studies have investigated the associations between resilience factors and substance use among SMY. In the present preregistered study, we examined the associations among three different forms of resilience factors (i.e., general social support, lesbian, gay, bisexual, transgender, and queer (LGBTQ)-identity affirmation, LGBTQ community involvement) and alcohol, nicotine, and cannabis use, as well as on positive and negative affect.

Method: SMY (n = 82, ages 15-19, 56.1% cisgender women, 84.4% White) completed a baseline assessment then a 30-day ecological momentary assessment study. Multilevel regression models evaluated within-day and between-person associations between resilience factors and odds of substance use (alcohol, nicotine, cannabis), substance use quantity on use days (alcohol, cannabis), positive affect, and negative affect.

Results: On the day level, general social support was associated with greater positive affect, lesser negative affect, and greater drinks on drinking days. LGBTQ-identity affirmation was associated with greater positive affect, lesser negative affect, and greater odds of nicotine use. LGBTQ community involvement was associated with greater positive affect.

Conclusions: These results highlight the nuanced ways that resilience may engender more positive affect and reduce negative affect while simultaneously promoting substance use. Future research disentangling the mechanisms connecting resilience and substance use among SMY is necessary. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Alcohol and cannabis are often perceived as pain-relieving. However, minimal work has examined whether people use and co-use these substances following pain in daily life.

Method: Forty-six adults reporting weekly use of alcohol and/or cannabis completed a 60-day ecological momentary assessment protocol, answering at least four daily reports on their alcohol and cannabis use and pain (n_assessments = 10,769 over 2,656 days). We examined whether self-reported pain so far that day (cumulative-average pain) was associated with subsequent alcohol and cannabis use and same-occasion co-use. Models also addressed whether associations differed for initiating versus continuing a use episode. Hypotheses were preregistered.

Results: A multinomial multilevel model found that cumulative-average pain was associated with a greater likelihood of same-occasion co-use in the continuation phase but not the initiation phase, compared to no use (OR = 1.48,95% CI [1.06, 2.06], p = .023) and alcohol use (OR = 1.52, CI [1.03, 2.26], p = .037). Cumulative-average pain was largely not associated with alcohol-only and cannabis-only use. After alcohol use, greater pain was associated with cannabis use (OR = 1.37, CI [1.11, 1.70], p = .004), but not the reverse. Secondary analyses found greater previous-occasion (not cumulative) pain was associated with initiation of alcohol use and number of drinks, and initiation and continuation of cannabis use, but not number of cannabis hits.

Conclusions: Although not all hypotheses were supported, pain was associated with subsequent substance use in this sample engaged in regular substance use and not recruited for chronic pain. Cumulative pain may be particularly related to alcohol-cannabis same-occasion co-use, which may increase the risk of substance use-related problems over time.

Objective: Early pubertal timing is a risk factor for substance use during adolescence. Fewer studies investigated whether early pubertal timing continues to predict substance use in late adolescence and adulthood, suggesting that long-term effects of pubertal timing vary across substances and by biological sex. Finally, existing studies on pubertal timing and substance use in adulthood involved predominantly White samples. Thus, this longitudinal study examined the concurrent and long-term effects of pubertal timing on alcohol, cigarette, and cannabis use together with sex differences in predominantly Black youth from the United States.

Method: The sample included 603 youth (52% male, 80% Black) who were interviewed in early adolescence (mean age: 13.2), late adolescence (mean age: 17.6), and young adulthood (mean age: 27.7). During early adolescence, youth self-reported their physical maturation based on Tanner scores, which were adjusted for age and used as indicators of pubertal timing. Youth self-reported their substance use at each time point.

Results: Early pubertal timing was associated with higher odds of alcohol use during early adolescence but did not predict alcohol use during late adolescence or adulthood. While early pubertal timing did not predict cigarette use at any time point, early pubertal timing predicted greater odds for cannabis use during early adolescence and higher rates of cannabis use in adulthood. Moreover, early pubertal timing predicted greater risk for couse of alcohol, cigarettes, and cannabis in adulthood. No effects differed by sex.

Conclusions: These findings suggest that links between pubertal timing and substance use vary across substances and developmental periods. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
