An Analysis of Drinking Motives in the Maintenance of Co-Occurring Obsessive–Compulsive Symptoms and Alcohol Misuse

Objective: Despite the commonly observed co-occurrence of obsessive–compulsive symptoms (OCS) and substance use in clinical populations, few researchers have examined potential mechanisms which contribute to this relationship. This study assessed the mediating role of drinking motives in the relationship between OCS, alcohol consumption, and its resulting health risks among U.S. adults. Methods: Adult participants (n = 1966; M age = 47.72, SD = 17.91; 76.30% female; 86.10% non-Hispanic White) sourced from Research Match answered an online questionnaire containing measures related to substance use and anxiety-related symptoms. Results: As hypothesized, there was a significant positive indirect path between OCS and both alcohol consumption and risky alcohol use through coping motives. However, there were also small indirect effects of OCS through social motivations for consumption and conformity motivations for risky alcohol use. Conclusions: These results add evidence that coping motives play a role in OCS and alcohol misuse and highlights the need to also consider drinking motives related to social facilitation and conformity in those with co-occurring OCS and alcohol misuse.

Coping motives as a mediator of the relationship between child maltreatment and substance use problems in south African adolescents

BackgroundEvidence suggests that adults with a history of child maltreatment (CM) engage in substance misuse driven by ‘coping motives’: maladaptive beliefs that substances help them cope with negative emotions. However, the specificity of this risk pathway is under-researched in younger and non-Western cohorts. ObjectiveThe present study aimed to determine whether coping motives play a distinct role compared to other motives for substance use in mediating the relationship between CM and problematic alcohol and marijuana use in a sample of South African adolescents. Participants and settingA sample of 688 high school students (M age = 15.03 years; 62.5 % female) in Cape Town, South Africa, completed a cross sectional survey. MethodsParticipants completed self-report measures of CM exposure, motives for using alcohol and marijuana (coping, enhancement, social and conformity), and alcohol and marijuana related problems. Participants who endorsed using alcohol (N = 180) or marijuana (N = 136) were included in analysis. A parallel mediation model was conducted for each substance (alcohol and marijuana, respectively) to assess which motives mediated the relationship between CM exposure and substance-related problems. ResultsCM exposure predicted both alcohol-and marijuana related problems. The relationship between CM exposure and alcohol-related problems was partially mediated by coping motives (p < .001, 95%CI 0.028, 0.115) and, to a lesser extent, conformity motives (p < .01, 95%CI 0.001, 0.041), but not by social motives or enhancement motives. The relationship between CM exposure and marijuana-related problems was partially mediated by coping motives (p < .001, 95%CI 0.004, 0.037), but not by conformity, social or enhancement motives. ConclusionsThe findings support the importance of coping motives as a mediator between CM and problematic substance use across different substances of abuse in South African adolescents, and the role of conformity motives in problematic alcohol use. Future research should explore whether these findings hold across other sociocultural contexts, and the utility of interventions to address coping motives for substance use in adolescence.

Cultural factors in alcohol and other drug use among immigrant youth in Western Australia: A qualitative investigation.

Our aim was to identify the influence of heritage cultural factors and mainstream Australian cultural norms on young culturally and linguistically diverse (CaLD) immigrants' alcohol and other drug (AOD) use attitudes, motives for use, and behaviors. We conducted nine focus groups with 55 youth (aged 16-30; 22 female, 33 male). Participants were from diverse cultural backgrounds including India, Sri Lanka, Ethiopia, Eritrea, Sudan, Hazara-Afghanistan, Burma (Chin and Karen), Malaysia, Singapore, and China. They were first- (80%) and second-generation immigrants to Australia. We constructed three overarching themes: bicultural conflict, freedom versus constraints, and the intersection of gender and culture. Although there were diverse responses, there was widespread recognition of perceived Australian norms around AOD use, particularly drinking alcohol. Our participants reported conformity motives that included fitting in with mainstream Australian culture. Drinking alcohol was also seen as a means for social bonding between immigrant and mainstream youth. Acculturation challenges of reconciling their heritage cultural identity with Australian identity contributed to problematic AOD use. Further research into the prevalence and predictors of AOD-related harm among CaLD youth in Australia is needed to tailor interventions that draw upon immigrant communities' resilience and enhance positive adaptation outcomes.

Understanding daily and momentary drinking motives among transgender and gender diverse adults

Background Transgender and gender diverse (TGD) adults may be at increased risk for alcohol use due to gender minority stress (GMS) and specific drinking motives. Aim The current study evaluated the relations between GMS and resilience, drinking motives, and alcohol outcomes among TGD adults. Methods Twenty-five primarily White TGD adults (7 transgender men, 7 transgender women, and 11 gender diverse) who were 19 years of age or older (mean: 32.60; SD: 10.82), lived in Canada, and drank regularly were prompted to complete surveys multiple times per day indexing drinking motives, GMS and resilience factors, contexts, and alcohol use and craving. Multilevel models examined predictors of each drinking motive and relations between drinking motives and alcohol outcomes at the daily and momentary levels. Results Days with increased GMS corresponded with increased social (p<.05) and conformity motives (p<.01). Days with increased resilience also corresponded with elevated social (p<.01) and conformity (p<.05) motives. Days with higher enhancement and social motives predicted increased alcohol use (ps<.01). All momentary motives were elevated when participants reported higher momentary resilience (p<.001). Significant associations between drinking motives, contexts, and alcohol craving were also evident. Discussion GMS and certain drinking motives may contribute to increased alcohol use and craving among TGD adults. Findings encourage the development of gender-inclusive interventions that address GMS and specific drinking motives to support a reduction in this population’s alcohol use.

Regression tree applications to studying alcohol-related problems among college students.

Machine learning algorithms hold promise for developing precision medicine approaches to addiction treatment yet have been used sparingly to identify predictors of alcohol-related problems. Recursive partitioning, a machine learning algorithm, can identify salient predictors and clinical cut points that can guide treatment. This study aimed to identify predictors and cut points of alcohol-related problems and to examine result stability in two separate, large data sets of college student drinkers (n = 5,090 and 2,808). Four regression trees were grown using the "rpart" package in R. Seventy-one predictors were classified as demographics (e.g., age), alcohol use indicators (e.g., typical quantity/frequency), or psychosocial indicators (e.g., anxiety). Predictors and cut points were extracted and used to manually recreate the tree in the other data set to test result stability. Outcome variables were alcohol-related problems as measured by the Alcohol Use Disorder Identification Test and Brief Young Adult Alcohol Consequences Questionnaire. Coping with depression, conformity motives, binge drinking frequency, typical/heaviest quantity, drunk frequency, serious harm reduction protective behavioral strategies, substance use, and psychosis symptoms best predicted alcohol-related problems across the four trees; coping with depression (cut point range: 1.83-2.17) and binge drinking frequency (cut point range: 1.5-2.5) were the most common splitting variables. Model fit indices suggest relatively stable results accounting for 17%-30% of the variance. Results suggest the nine salient predictors, particularly coping with depression motives scores around 2 and binge drinking frequency around two to three times per month, are important targets to consider when treating alcohol-related problems for college students.

An examination of cannabis use motives among couples with intimate partner violence and alcohol use disorder.

Cannabis use is highly prevalent among individuals with a history of intimate partner violence (IPV) and among people who drink alcohol. Motives for cannabis use are important correlates of consumption and problem severity. However, no research has examined cannabis use motives among couples with IPV. The goals of the study were to examine (1) the associations between a person and their partner's cannabis use motives; and (2) examine the extent to which each partners'cannabis use motives are related to their own and their partner's cannabis consumption. Participants were 100 couples (n = 92 different-sex couples, n = 8 same-sex couples) who reported physical IPV in their current relationship. Certain cannabis motives (coping and conformity) and behaviors (cannabis use frequency, quantity and drug-related problems) were positively associated between intimate partners. One's own higher coping motives were associated with greater frequency of cannabis consumption; higher conformity motives were associated with less quantity of consumption; higher social motives were associated with greater quantity of cannabis consumption; and one's partner's social motives were associated with less quantity of cannabis consumption. DISCUSSIONAND CONCLUSIONS: Findings suggest that couples report similar motives for cannabis use, and that one's own and their partner's motives may differentially influence frequency and quantity of use. This study provides novel information on congruency between cannabis use motives and behaviors between intimate partners, as well as how both an individual and their partner's motives for use can influence an individual's cannabis use behaviors.

Motives for MDMA Use: A Comparative Study with Alcohol and Cannabis

IntroductionWhile research on drug use motives has primarily focused on widely used substances like alcohol, tobacco, and cannabis, understanding the motivations behind MDMA use is crucial for developing targeted therapeutic, preventive, and harm reduction strategies.ObjectivesThe objective of this study is to present the findings of an online survey that evaluates the motives behind the use of 3,4-methylenedioxymethamphetamine (MDMA) and draws comparisons between these motives and those for alcohol and cannabis consumption.Methods Data were collected through an online survey, available in both English and French, with 99 participants. The survey included five sections, including a substance abuse screening test (ASSIST) and the Pahnke-Richards Mystical Experience Questionnaire. The primary focus was on motives for MDMA use, assessed using an adapted version of the Marijuana Motives Measure (MMM), comparing them with alcohol and cannabis motives.Results The most reported motive for MDMA use was enhancement, followed by expansion motives. Social motives were the third most common, while coping motives ranked fourth, and conformity was the least common motive. Comparisons with alcohol and cannabis use motives revealed differences in motives for each substance. MDMA showed a unique pattern of motives.ConclusionsEnhancement emerged as the most prevalent motive for MDMA use, consistent with previous research on MDMA motive use. Expansion motives, which involve altering perceptions and increasing self-awareness, ranked second, reflecting the growing interest in MDMA-assisted therapy for conditions like PTSD. Surprisingly, social motives were less common for MDMA compared to alcohol and cannabis, suggesting unique social dynamics associated with MDMA use. Conformity motives were also less significant for MDMA users, possibly due to the age of initiation and user maturity. Understanding the motives behind MDMA use is essential for designing effective interventions and harm reduction strategies. The distinct motives for MDMA, as compared to alcohol and cannabis, highlight the need for tailored approaches to address its use. Further research should explore the complex interplay of motives, age of initiation, social context, and cultural factors to inform comprehensive strategies related to MDMA use.Disclosure of InterestNone Declared

Substance Use Motives as Mediators of the Associations between Self-Control Constructs and Negative Substance Use Consequences: A Cross-Cultural Examination.

The present study sought to examine three distinct research questions: a) are self-control constructs (i.e., negative/positive urgency, self-regulation, and emotion-regulation) indirectly related to negative alcohol/marijuana consequences via substance use motives, b) to what extent are these indirect effects consistent across differing drugs (i.e., alcohol and marijuana), and c) are these models invariant across gender and countries. Participants were 2,230 college students (mean age=20.28, SD=0.40; 71.1% females) across 7 countries (USA, Canada, Spain, England, Argentina, Uruguay, and South Africa) who consumed alcohol and marijuana in the last month. Two (one for alcohol and one for marijuana) fully saturated path models were conducted, such that indirect paths were examined for each self-control construct and substance use motive on negative consequences (e.g., negative urgency → coping motives → negative consequences) within the same model. Within the comprehensive alcohol model, we found that lower self-regulation and higher negative urgency/suppression were related to more alcohol consequences via higher coping and conformity motives. For marijuana, we found that lower self-regulation and higher negative urgency/suppression were related to more marijuana consequences via higher coping motives (not significant for conformity motives). Unique to marijuana, we did find support for higher expansion motives indirectly linking positive urgency to more negative consequences. These results were invariant across gender groups and only minor differences across countries emerged. Prevention and intervention programs of alcohol and marijuana around university campuses may benefit from targeting self-control related skills in addition to motives to drug use to prevent and reduce negative drug-related consequences.

Drinking motives and alcohol use among undergraduate college students in Hawaiʻi: A cross‐sectional analysis on the moderating effects of ego‐resiliency and social support

AbstractThis study estimated the (1) levels of alcohol use, drinking motives, ego‐resiliency, and social support; (2) effect of drinking motives on alcohol use; and (3) moderating effects of ego‐resiliency and social support. An online survey was conducted among undergraduate college students from a university in Hawaiʻi (n = 172). This study estimated moderating effects of ego‐resiliency and social support between drinking motives and alcohol use using SPSS 26.0 and PROCESS macro version 4.0. Four independent moderation analyses were performed for each drinking motive (social, coping, conformity, and enhancement). About one‐fourth of the sample had drinking problems (AUDIT score ≥ 8). The highest drinking motive was social, followed by enhancement, coping, and conformity motives. Ego‐resiliency significantly moderated the relationship between coping and enhancement motives with alcohol use. Social support did not have a significant moderating effect between drinking motives and alcohol use. The findings suggest that undergraduate college students who drink with coping and enhancement motives may have a reduced risk of drinking problems if they have a high level of ego‐resiliency. Future research and practice need to account for drinking motives and ego‐resiliency when working with college students to prevent and intervene in excessive alcohol use.

Cannabis use amongst students attending an alternative provision in the United Kingdom

ABSTRACT For reasons explored within the paper, adolescents excluded from mainstream education are more likely to use cannabis regularly. Research into the cannabis use (CU) of adolescents excluded from mainstream school in the United Kingdom (UK) is limited and seldom focuses on what students perceive as effective support. In this exploratory study, information from 55 students attending an alternative provision (AP) in the North of England was gathered via electronic survey. Questions were asked about patterns of student CU, motivations for use, perceived impact on mental health and educational outcomes, and effective support. Current users reported CU was motivated by enhancement and coping motives, while conformity motives were less significant than expected. Past users endorsed coping motives less than expected. Support of trusted adults was perceived as the most effective support strategy. Findings are explored in relation to discussions with key staff prior to and after the survey. These reflect previous research into adolescent CU motives, and the positive impact of school connectedness on student CU. Recommendations include early intervention for high-risk youth based on accurate identification of CU motives. Staff should focus on building trusting relationships with students as a platform to support the management of adolescent CU.

Drinking and mental health in middle adulthood: exploring the impact of wellbeing, mental health literacy, and drinking motives on risk of alcohol dependence

Objectives Risky drinking is a concern among UK-based middle-aged adults. We aimed to explore the relationship between risky drinking, drinking motives, wellbeing, and mental health literacy (MHL). Method Cross-sectional analysis of online survey data completed by 193 UK-based adults aged 40–65 who drank alcohol, incorporating the Alcohol Use Disorders Identification Test (AUDIT); Drinking Motives Questionnaire-Revised (DMQ-R); Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS); Mental Health Literacy Scale (MHLS) and demographic questions. Results Coping, enhancement and conformity motives and gender significantly predicted higher AUDIT scores (measuring risky drinking). Enhancement motives were found to mediate the relationship between the self-help component of MHL and AUDIT scores, while coping motives mediated the association between wellbeing and AUDIT scores. Conclusion Findings support research emphasising the influence of drinking motives on risky drinking and highlights how low wellbeing may interact with coping motives to explain risky drinking among middle-aged adults, particularly men. Interventions supporting individuals to understand the relationship between drinking motives and risky drinking, develop adaptive coping strategies, and address the causes of low wellbeing, may be beneficial. However, as the sample was 84% ethnically White, 64% women, 85% educated to at least undergraduate level, and reported a relatively high mean socioeconomic status (6.98 out of 10), the results may not generalise beyond these groups. Future research should use stratified sampling to increase generalisability, as well as exploring whether alcohol-specific, component-specific, or disorder-specific MHL is associated with risky drinking and wellbeing.

The role of perceived parent drinking motives on alcohol use among adolescents with and without childhood attention-deficit/hyperactivity disorder.

Parent history of alcohol-related problems and antisocial behaviors contribute to adolescent alcohol use and are associated with offspring attention-deficit/hyperactivity disorder (ADHD). Youth with ADHD may be susceptible to intergenerational transmission of alcohol-related cognitions, which may model drinking motives that enhance risk for adolescent alcohol use. We examined whether childhood ADHD and parent history of alcohol use disorder, with or without antisociality, were associated with adolescents' perceptions of their parents' drinking motives and whether these perceptions predicted their alcohol use behaviors. Adolescents (N = 199; 56% with ADHD; Mage = 15.73) completed the Drinking Motives Questionnaire regarding perceptions of their parents' drinking motives. Participants subsequently reported their past-year alcohol use behaviors (Mage = 16.95). Parents reported their history of alcohol-related problems and antisocial symptoms. Covariates included adolescent gender (7% girls), race (9% self-identified Black), and parental education and marital status. Perceived parent drinking motives were highest for social and lowest for conformity motives, consistent with adult self-reports in the literature. Parent alcohol use and antisociality history predicted perceptions of parent drinking motives, and child ADHD only predicted perceptions of parent social drinking motives. Perceived parent drinking motives predicted adolescent alcohol use, but only among youth without ADHD. Findings reflect the potential importance of assessing adolescent perceptions of parent drinking motives for adolescents without ADHD and a possible need for supporting parents in communicating about their own alcohol use. Future research should consider alternative strategies (e.g., assessing implicit cognitions) for studying the link between alcohol-related cognitions and behaviors for adolescents with ADHD.

Exploring Drinking Motives and Alcohol Use in College Students: The Moderating Effects of Gender

ABSTRACT This study explored associations between drinking motives and alcohol use and the moderating effects of gender. The data used in this study was collected from a University in Hawai‘i, with a sample size of 172 participants. The key findings of the study are as follows: About 24.4% of the participants had drinking problems, as indicated by an AUDIT score of 8 or higher. Social motives were the highest drinking motives, followed by enhancement, coping, and conformity motives. Coping motives were significantly associated with alcohol use. Gender significantly moderated the association between coping motives and alcohol use. Based on these findings, the study highlights the importance of policies and intervention programs that consider the effects of drinking motives and gender on alcohol use in college students.

The relationship between self-control and internet gaming disorder and problematic social networking site use: the mediation effects of internet use motives.

This study aimed to explore the relationships between problematic social networking site use (PSNSU), Internet Gaming Disorder (IGD), internet use motives, and self-control among university students in China and Japan. Specifically, it investigated the indirect effects of self-control on IGD and PSNSU through various internet use motives, considering gender differences. A sample of 697 university students (465 females; 397 Chinese) was surveyed. Path analysis was conducted separately for male and female users to examine the relationships between self-control, internet use motives, IGD, and PSNSU. The results indicated that self-control had significant indirect effects on IGD through enhancement (β = 0.096**, p = 0.005), social (β = -0.090**, p = 0.007), and conformity (β = -0.117**, p = 0.001) motives, but these effects were observed only in the male group. Self-control also exhibited indirect effects on PSNSU through enhancement, social, coping, and conformity motives, with a greater impact observed on PSNSU than on IGD. Gender differences in mediating effects were identified, with males and females showing distinct patterns. The findings highlight the importance of understanding gender differences and motivational factors in problematic internet use. These insights contribute to a better understanding of how internet use motives influence IGD and PSNSU in different contexts.

Examining engagement effects in an adaptive preventive intervention for college student drinking.

This study determined the characteristics of engagement and whether engagement in an adaptive preventive intervention (API) was associated with reduced binge drinking and alcohol-related consequences. Incoming students were recruited for a sequential multiple assignment randomized trial (SMART; N = 891, 62.4% female, 76.8% non-Hispanic White) with an assessment-only control group. The API occurred during the first semester of college, with outcomes assessed at the end of the semester. The API involved two stages. Stage 1 included universal intervention components (personalized normative feedback [PNF] and self-monitoring). Stage 2 bridged heavy drinkers to access additional resources. We estimated the effect of engagement in Stage 1 only and in the whole API (Stages 1 and 2) among the intervention group, and the effect of the API versus control had all students assigned an API engaged, on alcohol-related outcomes. Precollege binge drinking, intention to pledge a fraternity/sorority, and higher conformity motives were most associated with lower odds of Stage 1 engagement. Action (readiness to change) and PNF engagement were associated with Stage 2 engagement. API engagement was associated with significant reductions in alcohol-related consequences among heavy drinkers. Compared to the control, we estimated the API would reduce the relative increase in alcohol-related consequences from baseline to follow-up by 25%, had all API students engaged. Even partial engagement in each component of the "light-touch" API rendered benefits. Analyses suggested that had all students in the intervention group engaged, the API would significantly reduce the change in alcohol-related consequences over the first semester in college.

The Associations Between Drinking Motives and Alcohol-Related Consequences in Graduate Students from Universities in the United States.

Many college students "mature out" of heavy drinking when they graduate. Yet, those who go onto graduate education report engaging in problematic drinking patterns. Drinking motives are one factor that uniquely predicts problematic drinking patterns in college students. Evidence suggests that these unique associations also generalize to individuals' post-college, specifically between drinking motives and specific alcohol-related consequences. However, no research to date has examined the association between drinking motives and alcohol-related consequences in graduate students. The current study aimed to examine the unique associations between drinking motives, and drinks per week and specific alcohol-related consequences. Participants included 330 graduate students from various universities in the United States, recruited through social media. The majority of participants were White (71.3%), 54.9% female identifying, with a mean age of 26. Results revealed that conformity motives were positively associated with drinks per week, self-control consequences, self-care consequences, risky consequences, academic/occupational consequences, and blackout consequences. Social motives were negatively associated with interpersonal consequences and academic/occupational consequences. Enhancement motives were negatively associated with drinks per week, and positively associated with academic/occupational consequences. However, coping motivation was not associated with any of the outcomes. These findings highlight the need to further understand how drinking motives influence specific types of alcohol-related consequences as these associations change post-college. Results can be used to better inform future prevention and interventions for this population.

PTSD Symptom Severity and Alcohol Use among Firefighters: The Role of Emotion Regulation Difficulties

Objective Heightened rates of posttraumatic stress disorder (PTSD) symptoms and alcohol use have been documented among firefighters. Emotion regulation difficulties (ERD) are clinically relevant to both PTSD and alcohol use. Few studies have examined the role of ERD in the association of PTSD symptoms with alcohol use severity and alcohol use motives among firefighters. Thus, the present investigation examined the indirect effect of PTSD symptom severity on alcohol use severity and alcohol use motives through ERD. Methods The sample was comprised of 685 firefighters (Mage = 38.65, SD = 8.57, 93.6% male) recruited from an urban fire department in the southern U.S. to complete an online survey. Indirect effects were calculated using 10,000 bootstrapped samples. Effects were examined after accounting for years of fire service, occupational stress, trauma load (i.e., number of traumatic event types experienced); in models evaluating alcohol use motives as outcomes, other alcohol use motives (i.e., alternate motives subscales) were included as additional covariates. Results First, ERD explained the association of PTSD symptom severity with alcohol use coping motives (β = .01, SE = .003, 95% CI [.004-.01]). Furthermore, ERD did not significantly account for the association of PTSD symptom severity with alcohol use severity (β = .02, SE = .01, 95% CI [-.004-.04]), alcohol use enhancement motives (β = −.003, SE = .002, 95%CI [-.007-.000]), alcohol use social motives (β = .004, SE = .002, 95% CI [-.000-.01]), or alcohol use conformity motives (β = −.002, SE = .002, 95% CI [-.006-.02]). Conclusions Results demonstrated that, among firefighters, PTSD symptom severity is positively related to alcohol use coping motives through heightened ERD. Clinical implications and future directions are discussed.

Posttraumatic stress and alcohol use among Hispanic/Latina survivors of interpersonal trauma: Associations with anxiety sensitivity and distress tolerance.

Hispanic/Latina students experience elevated rates of binge drinking, interpersonal trauma, and posttraumatic stress disorder (PTSD) symptoms. Research has indicated anxiety sensitivity (AS; i.e., fear of anxiety-related bodily sensations) and distress tolerance (DT; i.e., ability to tolerate negative emotional states) are modifiable psychological mechanisms related to alcohol use and PTSD symptoms. However, a dearth of literature has focused on factors that may account for associations between alcohol use and PTSD among Hispanic/Latina students. The project examined, among 288 Hispanic/Latina college students (Mage = 23.3 years, SD = 5.4) with interpersonal trauma histories, the indirect effects of PTSD symptom severity on (a) alcohol use and (b) alcohol use motives (i.e., coping, conformity, enhancement, social) via DT and AS, evaluated as parallel statistical mediators. Results PTSD symptom severity had an indirect effect on (a) alcohol use severity; (b) conformity motives for alcohol use; and (c) social motives for alcohol use via AS but not DT. PTSD symptom severity was associated with coping-oriented drinking via both AS and DT. This research has the potential to advance culturally-informed literature on factors that may impact co-occurring PTSD symptoms and alcohol use.

Measurement invariance of the Marijuana Motives Measure among men and women using Stop Cannabis App

BackgroundMotives to use cannabis play a central role in the development and maintenance of problematic cannabis use and previous studies stressed sex-related differences on motives to use cannabis. However, motives cannot be validly compared in men and women without first establishing the measurement invariance across sex. Therefore, the aim of the study is to (1) examine for the first time the measurement and structural invariance of the Marijuana Motives Measure (MMM) across sex, and (2) to investigate the motives for cannabis use that best explain problematic use. Methods2951 (41.7% women) users of the “Stop cannabis” smartphone app of which 99.8% reported having used cannabis in the last three months completed an online MMM and ASSIST to assess the severity of their problematic cannabis use. ResultsMultigroup confirmatory factor analyses supported measurement invariance across sex, whereas structural invariance was not confirmed. Indeed, group comparisons indicated that women reported greater coping motives then men whereas men showed greater social motives than women. A multiple linear regression analysis showed that only coping and conformity motives were significantly associated with greater problematic cannabis use, whereas neither sex nor the sex by motives interactions were significantly related to problematic cannabis use. ConclusionsThe MMM appears to function comparably across men and women. Therefore, sex-related comparisons on the questionnaire can be considered valid. Coping and conformity motives may play a central role part in the development of marijuana use problems which may hold implications for intervention development and public policy.

Motives and food craving: Associations with frequency of hyper-palatable food intake among college students

BackgroundCollege food environments provide wide access to hyper-palatable foods (HPF). Palatable eating motives and craving are individual factors that may impact HPF intake. Nevertheless, no study to date has examined the relationship between these factors and frequency of HPF intake in a dormitory all-you-can-eat-style cafeteria meal, a typical college food setting. MethodsCollege students (N = 218) self-reported frequency of HPF intake at a college cafeteria meal and their frequency of HPF intake in the overall diet. Quasipoisson and logistic regression models tested whether palatable eating motives (assessed via the Palatable Eating Motives Scale) and craving (assessed via the Food Craving Inventory) were associated with the rate of HPF intake during the cafeteria meal and excess frequency of HPF intake in the overall diet. ResultsCraving was associated with a 19% higher rate of HPF intake during the cafeteria meal (RR = 1.19; p = .015) and a >2-fold higher likelihood of excess frequency of HPF intake the overall diet (OR = 2.69; p < .001). Coping motive was associated with an 87% higher likelihood of excess frequency of HPF intake in the overall diet (OR = 1.87; p = .002), but not in the cafeteria meal. Reward enhancement, social and conformity motives were not significantly associated with the frequency of HPF intake in either setting. ConclusionsResults highlight the role of craving and coping motive in the frequency of HPF intake among college students. Prevention efforts may consider targeting craving and eating to cope to potentially address frequency of HPF intake among college students.
