Abstract
Alcohol and marijuana are two of the most widely used substances in the U.S, with rates of alcohol and marijuana co-use increasing in recent years. Despite this increase, little is known about the effects of alcohol and marijuana co-use patterns (e.g., simultaneous, concurrent) on intimate partner aggression (IPA) perpetration. The purpose of the current study was to examine differences in IPA among simultaneous and concurrent alcohol and marijuana use groups and an alcohol-only group. Participants were 496 individuals (57% identifying as a woman) recruited nationally in April 2020 via Qualtrics Research Services who reported being in a current relationship and recently consuming alcohol. Individuals completed an online survey that included demographics, measures of COVID-19 stress, alcohol and marijuana use, and physical and psychological IPA perpetration. Based on survey responses, individuals were categorized as belonging to the alcohol use only group (n = 300), the concurrent alcohol and marijuana use group (n = 129), or the regular simultaneous alcohol and marijuana use group (n = 67). Due to inclusion criteria, there was no marijuana use only group. Individuals with regular simultaneous or concurrent alcohol and marijuana co-use reported more frequent physical and psychological IPA perpetration compared to those who only used alcohol. Neither physical nor psychological IPA perpetration frequency differed between individuals who reported regular simultaneous versus concurrent alcohol and marijuana co-use. Results suggest that alcohol and marijuana co-use in general, and not the specific pattern of use, is associated with an increased likelihood of IPA perpetration.

Abstract
OBJECTIVE Alcohol use is an established risk factor for intimate partner aggression (IPA); however, few studies have considered whether couple drinking episodes increase the short-term likelihood of IPA episodes. The present ecological momentary assessment study considered the temporal effects of alcohol consumption on IPA perpetration and victimization within a sample of community couples at elevated risk of aggression. METHOD Mixed-sex (n = 191), same-sex male (n = 31), and same-sex female (n = 27) cohabiting couples (total N = 249; ages 21-35) made three independent, random reports for 30 consecutive days. Dyadic multilevel modeling was used to examine the impact of each partner's drinking episodes on the occurrence of verbal and physical perpetration and victimization events within the next 4 hr, using the actor-partner interdependence model. RESULTS Actor and partner alcohol use increased the likelihood of conflict and likelihood of conflicts involving verbal perpetration and victimization within the next 4 hr; alcohol effects on physical aggression were weaker. Actor alcohol effects on IPA remained significant after the addition of several control variables; partner effects did not. The absence of Alcohol × Gender interaction effects suggests that alcohol effects on IPA do not depend on actor or partner gender or their combination. CONCLUSIONS There are robust alcohol effects on the occurrence of verbal aggression perpetration and victimization episodes, with weak effects on physical aggression perpetration. Conflicts that include alcohol are not more likely to include aggression; rather, alcohol increases the likelihood of conflict occurring, with a proportion of those involving verbal aggression.

Abstract
The existing literature largely focuses on health risks and other pharmacodynamics of using cannabis, with fewer investigations of other normative psychological effects from consumption among otherwise healthy people. We measured several basic constructs of social psychology corresponding to the concept of prosociality among 146 healthy young adults between 18 and 25 years (M = 18.9, SD = 1.4) with varying detectable levels of tetrahydrocannabinol (THC) in their urine, controlling for participant’s sex, age, ethnicity, and childhood socio-economic status. Compared to THC-free individuals, cannabis users scored higher than non-users on validated measures of Prosocial Behaviors (d = .34, p = .04), the Empathy Quotient (d = .36, p < .01), Moral Harmlessness (d = .76, p < .01) and Moral Fairness (d = .49, p < .01), but exhibited a lower sense of Ingroup Loyalty (d = .33, p = .04). Relative to THC-free, same-sex individuals, female cannabis users scored significantly higher on measurements of Aggression (ds = .65 and .57, ps < .05) and male users scored higher on the Agreeableness dimension of personality (d = .91, p < .01).. Linear associations were found between the recency of last cannabis usage and the Prosocial Behaviors, Empathy Quotient, Moral Harmlessness, Moral Fairness and Agreeableness personality scores (rs from − .24 to .38, ps < .05). The findings suggest cannabis usage is associated with an increased sense of prosociality and prioritization of humanitarian behaviors that declines with time following cannabis consumption. Further research should focus on heterogeneity in the effects of cannabis consumption across users.

Abstract
Intimate partner violence (IPV) is a maladaptive conflict behavior, and IPV is both a precipitant and consequence of drug use problems among couples. It is unknown how drug use problem severity modulates the association between IPV and observed conflict behaviors. As part of a larger clinical trial, a sample of 30 different-sex substance-misusing couples completed self-report questionnaires and participated in a laboratory conflict resolution task. The current exploratory study tested whether drug use severity moderated the association between IPV perpetration and positive and negative conflict resolution behaviors, respectively, while controlling for IPV victimization. The results suggest that among men, drug use severity moderates the association between psychological IPV perpetration and negative conflict behaviors. Men who report more severe IPV display more negative behaviors when their drug use problems are more severe. Among women, drug use severity moderated the effect between psychological IPV perpetration and negative conflict behaviors among women, such that women with lower drug use problem severity displayed more negative conflict behaviors when psychological IPV perpetration was more versus less severe. Drug use severity also moderated the association between physical IPV perpetration and negative and positive conflict behaviors among women. That is, women who reported more severe physical IPV displayed more negative and fewer positive behaviors when their drug use problems were more severe. Results have preliminary implications for targeting conflict resolution strategies differentially in men and women with drug use and a history of IPV perpetration. Future studies should replicate the current findings in larger, more representative samples, and examine the role specific drugs have on the association between IPV and conflict behaviors.

Abstract
"Stealthing" is a form of sexual violence wherein a sexual partner purposefully removes a condom during penetration without the receptive partner's knowledge. Given the role of substance use in sexual violence broadly, we examined demographic and substance use correlates of stealthing perpetration (SP) and victimization (SV) among emerging adults. Participants comprised 2,550 18- to 25-year-olds (M age = 20.8, SD = 2.3), recruited via social media (48% female; 53.9% non-Hispanic White; 46.0% had another racial/ethnic identity; 67.4% heterosexual; 85.3% had some college education). Unadjusted analyses (t tests, χ2 analysis) and adjusted logistic regression analyses examined associations between demographics (age, education, race/ethnicity, sexual orientation) and substance use (binge drinking, marijuana use, other illegal drug use, and prescription drug misuse) with male SP and male and female SV. Five percent of males and 18.9% of females reported SV; 6.1% of males reported SP. In adjusted analyses, significant correlates of SP were: non-Hispanic White race/ethnicity (odds ratio [OR] = 0.39), binge drinking (OR = 1.39), cannabis use (OR = 1.37), and other drug use (OR = 1.43). Significant correlates of male SV were: non-Hispanic White race/ethnicity (OR = 0.28), non-heterosexual orientation (OR = 0.24), binge drinking (OR = 1.49), and other illegal drug use (OR = 1.79). Significant correlates of female SV were: older age (OR = 1.13), non-Hispanic White race/ethnicity (OR = 0.57), binge drinking (OR = 1.28), cannabis use (OR = 1.29), and other drug use (OR = 1.22). Consistent with literature linking alcohol to sexual violence, binge drinking correlated with both SV and SP, with other substance use also playing a role. Data are needed to explore these relationships using longitudinal, event-level assessments to investigate the influence of acute intoxication. Interventions to reduce sexually transmitted infections, unintended pregnancy, and sexual assault should include content on stealthing and substance use.

Do schizotypy features predict cannabis problems in partnered community adults? Addict Behav 2021; 116:106819.

Abstract
Schizotypy and its associated features-negative schizotypy, disorganization, and positive schizotypy-are correlated with increased cannabis use. Yet, it is unclear whether cannabis users with schizotypy are at greater risk of developing cannabis problems. Individuals with elevated schizotypy may be particularly vulnerable to cannabis problems. It is important to understand this association given the unknown harms of chronic cannabis use. Data for these analyses were drawn from a larger investigation of cannabis use in adult romantic relationships. Participants were community adults (N = 366; M Age = 24.6, SD = 3.1) who reported regular use of cannabis. Participants completed baseline surveys measuring cannabis use frequency, problems, and schizotypy. Follow-up assessments of cannabis problems and frequency were completed 4-, 7- and 10-months post-baseline. Multiple regression was used to test the effect of schizotypy-measured using the Schizotypal Personality Questionnaire-Brief (SPQ-B, Raine & Benishay, 1995)-on cannabis use problems controlling for 30-day cannabis use. At baseline, disorganization and positive schizotypy were associated with cannabis use, primarily for women. Results revealed that with cannabis use frequency in the model, the Disorganization subscale of the SPQ-B predicted cannabis problems at baseline and all 3 follow-up assessments. Results are consistent with research suggesting that those exhibiting odd behaviors report more problematic cannabis use. Future research may further this line of inquiry with a focus on longitudinal, reciprocal relationships among schizotypy features, cannabis use, and cannabis problems.

Abstract
Intimate partner violence (IPV) is a pervasive public health problem. Within the U.S., urban emergency department (ED) patients have elevated prevalence of IPV, substance use, and other social problems compared to those in the general household population. Using a social-ecological framework, this cross-sectional study analyzes the extent to which individual, household, and neighborhood factors are associated with the frequency of IPV among a socially disadvantaged sample of urban ED patients. Confidential survey interviews were conducted with 1037 married/partnered study participants (46% male; 50% Hispanic; 29% African American) at a public safety-net hospital. Gender-stratified multilevel Tobit regression models were estimated for frequency of past-year physical IPV (perpetration and victimization) and frequency of severe IPV. Approximately 23% of participants reported IPV. Among men and women, impulsivity, adverse childhood experiences, substance use, and their spouse/partner's hazardous drinking were associated with IPV frequency. Additionally, household food insufficiency, being fired or laid off from their job, perceived neighborhood disorder, and neighborhood demographic characteristics were associated with IPV frequency among women. Similar patterns were observed in models of severe IPV frequency. IPV prevention strategies implemented in urban ED settings should address the individual, household, and neighborhood risk factors that are linked with partner aggression among socially disadvantaged couples.

An ecological momentary assessment study of community couples. Aggress Behav 2020; 46:547-558. [PMID: 32654252 DOI: 10.1002/ab.21915] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Revised: 06/08/2020] [Accepted: 06/23/2020] [Indexed: 11/10/2022]
Abstract
Intimate relationship functioning depends upon the ability to accommodate one's partner and to inhibit retaliatory and aggressive impulses when disagreements arise. However, accommodation and inhibition may be difficult when self-control strength is weak or depleted by prior exertion of self-control. The present study considered whether state self-control depletion prospectively predicts male and female self-reports of anger with partner and arguing with partner. Consistent with the I3 Model (Finkel, 2014, Adv Exp Soc Psychol, 49, 1-104), we also considered whether the association between elevated anger and arguing (i.e., instigation) and partner aggression was stronger when state self-control (i.e., inhibition) was depleted or among people high in negative urgency. In this ecological momentary assessment (EMA) study, heavy drinking married and cohabiting heterosexual couples (N = 191) responded to three randomly signaled reports each day for 30 days. Depletion predicted anger and arguing with partners both cross-sectionally and prospectively for men and women. However, after controlling for prior levels of anger and arguing, these effects were diminished, and supplemental analyses revealed that anger and arguing with partner predicted subsequent depletion. Anger and arguing were strongly associated with concurrent reports of partner aggression perpetration and victimization (verbal and/or physical). However, neither state self-control depletion nor negative urgency moderated these effects. Overall, results suggest a modest impact of depletion on daily couple functioning as well as a potential cyclical effect of arguing on depletion.

Abstract
BACKGROUND AND OBJECTIVES There is a well-established causal link between substance use and intimate partner violence (IPV) perpetration and victimization. However, little is known about the complex emerging relationship between cannabis use and IPV. Because cannabis is the most commonly used drug in the United States and is associated with numerous IPV risk factors such as alcohol use, it is important to examine this relationship in greater detail. METHOD The current exploratory study examined the association between (a) self-reported cannabis use during the past 90 days and (b) Δ9-tetrahydrocannabinol (THC) urine drug screens and IPV perpetration and victimization in a sample of 30 alcohol or drug-misusing community couples (N = 60 individual participants). RESULTS The majority of participants (n = 50 individuals, 83.3%) had concordant cannabis self-reported and urine drug screen results. After accounting for demographic variables and quantity and frequency of alcohol and stimulant use, greater quantity and frequency of cannabis use as well as positive THC urine drug screen results were associated with greater physical IPV victimization, and greater quantity and frequency of cannabis were associated with greater IPV psychological victimization and perpetration, and physical IPV victimization. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Findings emphasize the unique and important role that cannabis plays in the occurrence of IPV among intact couples. Findings also underscore the feasibility and utility of integrating confirmatory biological samples into future studies on this topic in order to advance the science in this area.

Daily patterns of substance use and violence among a high-risk urban emerging adult sample: Results from the Flint Youth Injury Study. Addict Behav 2020; 101:106127. [PMID: 31645000 PMCID: PMC6999833 DOI: 10.1016/j.addbeh.2019.106127] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Revised: 09/04/2019] [Accepted: 09/09/2019] [Indexed: 12/14/2022]
Abstract
OBJECTIVE Interpersonal violence is a significant public health problem, with substance use a key risk factor. Intensive longitudinal methods (ILMs) provide data on daily patterns/relationships between substance use and violence, informing prevention. Prior daily research has not focused on these relationships among urban minority samples. METHODS Within an RCT comparing ILM assessment/schedule methods, 162-participants completed daily IVR (n = 81) or SMS (n = 81) assessments measuring 19 substance use and violence (partner/non-partner) behaviors daily for 90-days. GLMMs characterized between- and within-person predictors of daily violence. RESULTS Participants [48.7%-female; age = 24.4; 62.3%-African-American; 66.7%-public assistance] completed an average of 46.5 daily reports [SD = 26.7]. Across 90-days, alcohol was characterized by episodic weekend use (average = 10 days-of-use, 34.4% drinking-days involved binge-drinking), while marijuana use was continuous (average = 27 days-of-use; 1.7 times/day), with no weekend differences. Among 118-violent conflicts, 52.5% occurred on weekends; 57.6% were with non-partners/peers; 61.0% involved perpetration/57.6% victimization; and 52.5% involved severe violence. For violence conflicts, 27.1% were preceded by alcohol/22.9% preceded by drug use. Between-person predictors of daily violence included retaliatory attitudes (AOR = 3.2) and anxiety (AOR = 1.1). Within-person predictors included weekends (AOR = 1.6), binge drinking (AOR = 1.9), non-medical prescription opioid use (AOR = 3.5) and illicit drug use (AOR = 8.1). CONCLUSION Among a high-risk urban minority sample, we found that higher baseline retaliatory attitudes and anxiety, as well as same-day binge drinking, non-medical prescription opioid use, and illicit drug use were associated with daily violence, likely reflecting both pharmacological and socio-contextual factors. Addressing substance use and retaliatory violence with tailored prevention efforts may aid in decreasing negative interpersonal violence outcomes.

[PMID: 33192691 PMCID: PMC7525024 DOI: 10.3389/fpsyt.2020.567887] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 08/27/2020] [Indexed: 01/07/2023] Open
Abstract
There has been a shift surrounding societal and legal perspectives on cannabis reflecting changing public attitudes towards the perceived safety and social acceptability of cannabis use. With cannabis liberalization internationally, the focus of most cannabis-related harms has been on effects with users themselves. Harm-to-others including injuries from violence have nevertheless been unfortunately largely overlooked. While studies remain heterogeneous, there is meta-analytical evidence pointing towards an association. The aims of this focused review are two-fold: (I) review the evidence from meta-analyses on the association between cannabis and violence; and (II) provide an overview of possible mechanisms relating cannabis use to violence. First, evidence from meta-analytical studies in youths, intimate partners, and individuals with severe mental disorders have shown that there is a global moderate association between cannabis use and violence, which is stronger in the latter more at-risk population. Preliminary data has even highlighted a potential dose-response relationship with larger effects in more frequent users. Although of importance, this subject has remained essentially forgotten as a public health concern. While literature remains inconclusive, data has suggested potential increases in cannabis use following liberalization policies. This may increase violent outcomes if the effect is directly related to the use of cannabis by means of its psychophysiological modifications. However, for the moment, the mechanisms associating cannabis use and violence remain to be clearly resolved. Considering the recency of policy changes on cannabis, further methodologically sound research using longitudinal designs should examine the effects that cannabis use may have on different forms of violence and the trends that emerge, while evaluating the effects of possible confounding factors (e.g. other substance use). In addition, as evidence-based research from meta-analyses have shown that cannabis use is associated with violence, measures must be taken to mitigate the risks.

Abstract
Several theories posit that cannabis and other substances are used to reduce negative affect. This daily report study considered whether variations in positive and negative affect, reported each morning, contributed to the likelihood of cannabis use later that day. We also explored whether levels of positive and negative affect reported immediately after cannabis use improved, relative to that day's morning levels. The sample included 183 men and 183 women representing heterosexual, cannabis-using couples from the community. Participants made independent, daily reports of affect and cannabis use episodes for 30 consecutive days. Using multilevel modeling, we modeled men's and women's use of cannabis on a given day as a function of morning levels of positive, hostile, and anxious affect, accounting for partner cannabis use that day, and mean levels of positive and negative affect. Men and women were more likely to use cannabis on a given day when morning positive affect was lower than typical for the person and when partner used cannabis that day. Neither hostile nor anxious affect contributed to later use of cannabis. Immediately after cannabis use, positive affect increased, and hostile and anxious affect decreased relative to that day's morning levels. The improved affect immediately after use suggests a mechanism of positive reinforcement.

Abstract
Recent research on substance use in committed relationships covers three general areas. First, partners tend to be concordant for substance use, and concordance is at least partially the result of partner influence (or convergence). Second, substance use (particularly discrepant use) predicts relationship outcomes such as lower relationship quality and greater conflict, intimate partner aggression, and risky sex. Concordant use, however, can be protective. Finally, relationship variables, such as conflict, intimate partner aggression, and support for cessation, predict substance use. Recent advances in methodological innovation, such as the use of longitudinal designs and dyadic data, are noted. Although the field has moved in some new directions conceptually, the research in this area is still relatively atheoretical. Suggestions for future research directions are discussed.

Abstract
Although marijuana use has been linked to negative consequences for intimate relationships, an emerging literature suggests that under some circumstances it may have positive consequences. Couples who use substances together report better relationship functioning over time and may experience positive short-term outcomes. Using a sample of 183 heterosexual, frequent marijuana-using couples from the community, reporting over 30 consecutive days, we examined whether marijuana use episodes were associated temporally with reports of couple intimacy experiences within the next two hours. We used multilevel modeling, within an Actor Partner Interdependence Model (APIM) framework, modeling male and female outcomes simultaneously. Consistent with hypotheses, simultaneous marijuana use (male and female partners reported use at the same hour) increased the likelihood of an intimate experience for both men and women. However, we also found positive effects for Actor and Partner solo marijuana use on male and female reports of intimacy events. When analyses were limited to marijuana use episodes in which the respondent reported on presence of partner, we found that positive effects on intimate experiences were limited to marijuana use episodes in which partner was present; use without partner did not influence likelihood of intimacy. The robust positive effects of using marijuana with one's partner on intimacy events may serve to reinforce continued couple use and explain the positive effects of concordant substance use on relationship functioning over time.

Abstract
BACKGROUND Among college students, interpersonal conflict with others is a common, yet stressful negative interpersonal experience. Research suggests that drinking episodes may contribute to the occurrence of conflict. Marijuana use, independently or in conjunction with alcohol, may also influence the likelihood of subsequent conflict. OBJECTIVES We considered the temporal effects of independent and simultaneous alcohol and marijuana use episodes on the occurrence of interpersonal conflict. Use of multilevel modeling allowed us to distinguish the within-person effects of substance use from between-person differences in frequency of use. METHODS Within a sample of 427 college freshman males over 56 days of daily reports, we examined the independent and interactive effects of episodes of alcohol and marijuana on the odds of conflict within the next 1-, 2-, 3-, and 4 hours. RESULTS Multilevel modeling analyses showed that drinking episodes increased the likelihood of conflict occurring within the next 1, 2, 3, and 4 hours. Marijuana had weaker positive effects, significant only within the 2 hour window. There were no alcohol by marijuana interaction effects in any analysis. CONCLUSIONS/IMPORTANCE Both marijuana and alcohol independently increased the likelihood of interpersonal conflict; however, the marijuana effect appeared less robust. As marijuana use becomes more normative and accessible for college students, it is important to understand the extent to which marijuana use results in negative consequences and the contexts under which these effects unfold.

Abstract
Intimate couples with discrepant use of alcohol and other drugs experience poorer relationship functioning relative to couples with concordant use or nonuse. Within a sample of marijuana-using couples, we hypothesized that greater discrepancy in marijuana use frequency between partners would be associated with lower relationship satisfaction and perceived partner responsiveness and with greater conflict, negative interpersonal exchange, and psychological and physical aggression. The Actor Partner Interdependence Model (APIM) allowed us to account for the effects of each partner's marijuana use, as well as the discrepancy between partners' use, on his or her own perceptions of relationship functioning. Using multivariate, two-level models, we considered both between-couple and within-couple effects of partner marijuana discrepancy using 4 waves of data collected over 10 months. The sample consisted of heterosexual community couples (ages 18-30) in which at least one partner reported using marijuana two or more times per week. For several outcome measures, we observed negative within-couple discrepancy effects on reports of relationship functioning: at time points when absolute discrepancy in marijuana use was greater than typical for the couple, relationship functioning was poorer. The pattern was the same regardless of whether it was the male or female partner who used more frequently. There were also some negative between-couple effects associated with more frequent female use. Findings replicate and extend prior research on partner discrepancy by demonstrating the dynamic nature of these effects over time. (PsycINFO Database Record
