Validation of factor structures of the Drinking Motives Questionnaire among the Czech young and adult general population

BackgroundAlcohol use is one of the leading public health concerns in the Czech Republic. Drinking motives play a vital role in both initiation and subsequent alcohol use. A revised version of the self-report Drinking Motives Questionnaire (DMQ-R) has been proposed to assess these motives. The present study aims to validate the DMQ-R in the Czech general population.MethodsA total sample of 1,784 Czech participants completed a national survey. For the analysis, only a sub-sample of the past 12 months alcohol users was used: N = 1,123; 52.8% male; mean (SD) age = 40.2 (13.3). Drinking motives were assessed by the adopted Czech version of the DMQ-R. Both confirmatory (CFA) and exploratory factor analysis (EFA) were conducted to examine the factorial structure of the instrument. The age of the participant was additionally considered in the analysis (15–24 years as opposed to 25–64 years).ResultsThe CFA supported the four-factor model in the 25–64 age group. The analysis supported the construct validity of the Social, Conformity, and Coping factors. The Enhancement factor retained only two items and was found to refer more to a domain of ‘Pleasant Feeling’. For the 15–24 age group, the hypothesised four-factor structure was not corroborated.ConclusionsThe Czech version of the DMQ-R was found to be a reliable measurement tool of the Social, Conformity, and Coping motives. Future research should investigate the dimensionality of the instrument items presumed to correspond to the Enhancement motives. This should be conducted particularly among adolescents and young adults aged 15–24 years, where administering the DMQ-R with a large enough sample is also needed.

Associations between alcohol consumption and empathy in a non-clinical sample: drinking motives as a moderator

People consume alcohol for multiple reasons. Negative motives are often associated with alcohol-related problems. These problems might be explained by negative effects of high alcohol consumption on empathy. Past studies have associated alcohol use disorder (AUD) with reduced cognitive and affective empathy. Few studies have focused on non-clinical samples and considered behavioral empathy. We examined the links between alcohol consumption and multiple aspects of empathy, and if these links were moderated by negative drinking motives. We collected online data of 520 unselected individuals. All completed the AUD Identification Test (AUDIT) and a Drinking Motives Questionnaire. Affective and cognitive empathy were assessed using the Empathy Quotient. Behavioral empathy was assessed by asking participants how likely they would help the person in each of 24 scenarios involving pain. Helping others in pain was positively predicted by affective and cognitive empathy. Higher AUDIT scores were associated with helping others less, particularly among participants who scored higher on drinking to cope with negative affect. People who drink more and do so to cope with negative affect appear to have less behavioral empathy. This supports the view that negative drinking motives contribute to AUD risk.

Drinking to cope as a mediator of the relationship between stress and alcohol outcomes

Relationships between stress and alcohol consumption, alcohol dependence, and alcohol harms as mediated by drinking to cope and moderated by gender and education were investigated. Australian participants completed online surveys during 2020 (T1: n = 589, M age = 51.3, 67.7% female; T2: n = 493; T3: n = 487; T4: n = 311). Participants completed the Depression Anxiety and Stress Scales stress subscale, the Drinking Motives Questionnaire for Adults ‘Drinking to cope’ subscale, and the Alcohol Use Disorders Identification Test. T1 drinking to cope mediated the relationship between T1 stress and alcohol consumption at all time points (R 2 T1 = 0.24, R 2 T2 = 0.17, R 2 T3 = 0.21, R 2 T4 = 0.11). T4 drinking to cope mediated the relationship between T1 stress and T4 alcohol consumption (R 2 T1 = 0.15). Furthermore, a stronger effect was found for men in the relationship between T1 stress and T4 alcohol consumption as mediated by T4 drinking to cope (R 2 T4 = .18). No other relationships were found. Overall, drinking to cope appears to explain some of the increase in alcohol consumption across time due to stress and patterns of drinking to cope with stress appear to develop more strongly over time for men.

Drinking motives, personality traits and life stressors-identifying pathways to harmful alcohol use in adolescence using a panel network approach.

Models of alcohol use risk suggest that drinking motives represent the most proximal risk factors on which more distal factors converge. However, little is known about how distinct risk factors influence each other and alcohol use on different temporal scales (within a given moment versus over time). We aimed to estimate the dynamic associations of distal (personality and life stressors) and proximal (drinking motives) risk factors, and their relationship to alcohol use in adolescence and early adulthood using a novel graphical vector autoregressive (GVAR) panel network approach. We estimated panel networks on data from the IMAGEN study, a longitudinal European cohort study following adolescents across three waves (aged 16, 19 and 22 years). Our sample consisted of 1829 adolescents (51% females) who reported alcohol use on at least one assessment wave. Risk factors included personality traits (NEO-FFI: neuroticism, extraversion, openness, agreeableness and conscientiousness; SURPS: impulsivity and sensation-seeking), stressful life events (LEQ: sum scores of stressful life events), and drinking motives [drinking motives questionnaire (DMQ): social, enhancement, conformity, coping anxiety and coping depression]. We assessed alcohol use [alcohol use disorders identification test (AUDIT): quantity and frequency] and alcohol-related problems (AUDIT: related problems). Within a given moment, social [partial correlation (pcor) = 0.17] and enhancement motives (pcor = 0.15) co-occurred most strongly with drinking quantity and frequency, while coping depression motives (pcor = 0.13), openness (pcor = 0.05) and impulsivity (pcor = 0.09) were related to alcohol-related problems. The temporal network showed no predictive associations between distal risk factors and drinking motives. Social motives (beta = 0.21), previous alcohol use (beta = 0.11) and openness (beta = 0.10) predicted alcohol-related problems over time (all P < 0.01). Heavy and frequent alcohol use, along with social drinking motives, appear to be key targets for preventing the development of alcohol-related problems throughout late adolescence. We found no evidence for personality traits and life stressors predisposing towards distinct drinking motives over time.

Why do adults drink alcohol? Development and validation of a Drinking Motives Questionnaire for adults.

The Drinking Motives Questionnaire-Revised (DMQ-R; Cooper, 1994) is frequently used to assess adult drinking motives despite being designed for younger drinkers. This study aimed to develop and validate a Drinking Motives Questionnaire for Adults (DMQ-A). A convenience sample of 1,617 adults (25-65-year-olds; Mage = 51.4, SD = 10.8; 67% female) and 145 young-adults (18-24-year-olds; Mage = 20.8, SD = 2.0; 72% female) who reported drinking at least monthly were asked how often they consumed alcohol due to 53 drinking motives. Using item endorsement and exploratory factor analysis on half of the split sample of adults, 20 items were selected for the DMQ-A. The DMQ-A was found to have social, coping, confidence, taste, and enhancement dimensions. The DMQ-R conformity dimension was replaced by one of drinking for confidence and a novel drinking for taste dimension was identified. The second half of the split sample was used to demonstrate the DMQ-A's adequate model fit (CFI = 0.93), good internal consistency (α = .81-.90) and 6-month test-retest reliability (r = .65-.74), correlation with corresponding DMQ-R dimensions (r = .90-.96), and better model fit for adults than young-adults (ΔCFI = .03). The DMQ-A also demonstrated higher endorsement for each of its dimensions and better model fit than the DMQ-R among adults (ΔCFI = .05). Like the DMQ-R, DMQ-A coping and enhancement dimensions correlated with alcohol consumption and harmful drinking (r = .19-.42). The DMQ-A is a promising tool for future research or clinical application involving adult alcohol use. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Hazardous alcohol use, drinking motives and COVID-19-related anxiety in college students

Objective This study examined the associations of anxiety and drinking motives with hazardous and binge alcohol use among young adults. Participants We recruited young adults (N = 182, mean age 25) between November 2020 and December 2020. Methods Linear regressions were used to evaluate relationships among hazardous alcohol use (US Alcohol Use Disorders Identification Test-C [USAUDIT-C]), binge drinking (Alcohol Intake Questionnaire [AIQ]), PROMIS-Anxiety, COVID-19 related anxiety (CAS), and the drinking to cope with depression and anxiety subscales of the Modified Drinking Motives Questionnaire. Results Sixty-two percent of participants reported hazardous drinking (USAUDIT-C score > 4). PROMIS Anxiety and CAS scores were 63.7 and 1.0, respectively. Scores were positively associated with drinking patterns. However, the drinking to cope with depression motive significantly mediated these associations. Conclusions After the onset of the pandemic, hazardous and binge drinking patterns among young adults were associated with drinking to cope with depression rather than anxiety.

Increased alcohol use to cope with COVID-19-related anxiety one year into the coronavirus pandemic.

Background: An increase in drinking to cope with anxiety provoked by the coronavirus was observed during the first few months of the COVID-19 pandemic. Objective: In the present study, we examined the role of drinking motives in the anxiety-alcohol link one year into the pandemic. Methods: Using a cross-sectional design, we collected data between April and May 2021: 678 participants located in Romania or the Netherlands completed an online survey on alcohol consumption in the past month (assessed using a simple quantity-frequency measure), change in drinking during the past year (assessed using a single item asking whether there had been an increase, decrease or no change), drinking motives (assessed using the Revised Drinking Motives Questionnaire), drinking-related problems (assessed using the Alcohol Use Disorder Identification Test), and COVID-19-related anxiety (assessed using the Coronavirus Anxiety Scale). Results: Compared to before the pandemic, while 42% of participants had decreased their alcohol consumption, 15% reported an increase. Participants with clinically relevant COVID-19-related anxiety (11%) were more likely to drink to cope with negative affect, enhance positive affect, and conform to others. The association between COVID-19-related anxiety and drinking-related problems was specifically moderated by drinking to cope, such that the anxiety-alcohol link was stronger in participants who endorsed this drinking motive more. Conclusion: Drinking is a maladaptive coping strategy for individuals with high levels of COVID-19-related anxiety. These individuals might benefit from interventions involving the learning of healthier skills to deal with the ongoing pandemic.

The direct effect of drinking to cope on alcohol problems is not mediated by alcohol consumption: Invariance across gender and countries

BackgroundDrinking to cope with negative affect confers a direct risk of alcohol problems independently of greater alcohol consumption (i.e., confers susceptibility to the alcohol harm paradox). However, it remains unclear whether this risk is common across gender and countries. MethodsThe current study applied path analysis to two cross-sectional samples of 18–25-year-old undergraduate hazardous drinking students recruited from the UK (Study 1; N = 873) and internationally (Study 2; N = 4064 recruited in Argentina, Canada, South Africa, Spain, Uruguay, USA, and England). The Drinking Motives Questionnaire (DMQ) measured drinking to cope with negative affect and drinking to enhance positive affect (i.e., enhancement motives). The Alcohol Use Disorders Identification Test (AUDIT) measured alcohol consumption and problems. ResultsIn both studies, drinking to cope with negative affect had a direct effect on alcohol problems (S1: β = 0.259, SE = 0.031, p <.001; S2: β = 0.255, SE = 0.017, p <.001), and only a negligible proportion of this effect was mediated by alcohol consumption (S1: 2.58 %, p =.550; S2: 0.79 %, p=.538). By contrast, drinking to enhance positive affect had a smaller direct effect on alcohol problems (S1: β = 0.000, SE = 0.033, p =.989; S2: β = 0.044, SE = 0.017, p =.009), and a substantial proportion of this effect was mediated by greater alcohol consumption (S1: 99.76 %, p <.001; S2: 60.36 %, p <.001). Crucially, in both studies, the direct effect of drinking to cope on alcohol problems was invariant across gender and countries. ConclusionsThese findings suggest that individuals who endorse drinking to cope with negative affect are uniquely susceptible to the alcohol harm paradox, that is, greater alcohol problems which cannot be explained by greater alcohol consumption, and this susceptibility is common across gender and countries.

Gender-specific characteristics of alcohol use in community-dwelling older adults in Belgium

ABSTRACT Objectives Gender has been identified as an important social determinant for health. This study investigates gender-specific characteristics for alcohol use (AU) among community-dwelling older adults. Methods This is a retrospective cross-sectional study in 1.406 community-dwelling older adults. We used standardized questionnaires to collect self-reported data on alcohol use behavior, mental health, drinking motives and resilience by using, respectively, the Alcohol Use Identification Test (AUDIT), the Brief Symptom Inventory (BSI), the Drinking Motives Questionnaire (DMQ), and the Connor-Davidson Resilience Scale (CD-RISC). Multiple linear regression was used to identify the joint contribution of those factors on AU. Hierarchical regression was used to investigate the influence of the interaction between gender and those factors on AU. Results Linear regression analyses showed different associations with AU in men and women. Hierarchical regression analyses showed that gender presented a two-way interaction effect with enhancement and anxiety variables related to AU. Conclusions Different characteristics were found as predictors for AU among older men and women. Clinical implications Clinicians and health-care providers should be aware of these differences in order to provide tailored screening and intervention programs to reduce AU in older adults.

Drinking to cope as a mechanism between sleep problems and heavy episodic drinking among trauma survivors.

Objective: Women who have experienced trauma report high rates of heavy episodic drinking (HED) and sleep problems. Prior work suggests that poor sleep exacerbates heavy alcohol use; however, potential mechanisms for this association are unclear. Consistent with the self-medication model, one possibility may be that women with a history of trauma are drinking at increased rates in order to cope with the affective consequences of poor sleep. To examine this possibility, the current study tested the role of drinking to cope motives as a mediator of prospective associations between sleep problems and HED among women who have experienced trauma. Method: Community women reporting a history of trauma (N = 414, Mage = 21.8, 59.9% White, 36.2% Black) completed self-report measures at baseline and 4 month and 8 month follow-ups. Measures of trauma exposure (Life Events Checklist [LEC]) and sleep problems (Cohen-Hoberman Inventory of Physical Symptoms-Revised [CHIPS-R]) were taken from baseline, drinking motives (Revised Drinking Motives Questionnaire) at 4 months, and HED at 8 months. Results: Findings supported an indirect association between sleep problems and later HED through increased drinking to cope motives (b = .05, 95% CI [.018, .108], β = .05). Conclusion: As hypothesized, drinking to cope accounted for associations between sleep problems and later HED. Findings underscore the potential value in addressing drinking to cope motives as a means of reducing HED, particularly among women with a history of trauma who are sleeping poorly.

Consequences, Motives, and Expectancies of Consumption as Predictors of Binge Drinking in University Women.

The increasing presence of women, especially university women, in risky alcohol consumption such as Binge Drinking (BD), which is associated with gender-specific biopsychosocial problems, makes it necessary to analyze the variables underlying BD in order to adjust possible interventions more in line with their reality. The motives and expectancies of this pattern of consumption, as well as the consequences derived from it, are some of the variables that are shown to have the greatest weight in the prediction of BD. In the present study we analyze, on the one hand, the performance of these variables among college women with alcohol use, and on the other hand, which of these variables allow us to classify BD. A total of 501 female university consumers of alcohol (mean age 19.02 years) were assessed. Specifically, they completed a self-report of alcohol consumption (77.1% engage in BD), the Expectancy Questionnaire (EQ), the Drinking Motives Questionnaire (DMQ-R) and the Alcohol Consumption Consequences Evaluation (ACCE). BD female students scored significantly higher on these instruments, except for compliance motives. The logistic regression analysis carried out to estimate the probability of performing BD using the social and conformity motives, the ACCE and positive expectancies correctly estimated (χ28 = 9.149, p < 0.33) 88.6% of the cases and explained 26.2% of the BD. Thus, young women with a level of consequences classified as high risk (>25 in ACCE) have a 3.55-fold increase in the probability of having BD, compared to women classified as low risk by the ACCE. On the other hand, women classified as moderate risk by the ACCE have a 4.77-fold increase in the probability of having BD. In the case of social motives and positive expectancies, their increase multiplies by 1.165 and 1.024, respectively, the probability of having BD. The results of this study highlight the importance of adapting preventive measures to the consequences experienced by BD university students, especially in relation to the social motives and positive expectancies that modulate decision-making when engaging in this pattern of consumption.

Validity and usefulness of the short form of the Drinking Motives Questionnaire Revised (DMQ-R SF) among patients with schizophrenia

ObjectiveDrinking motives are considered to be major predictors of alcohol consumption and alcohol-related problems. However, these motives have been poorly investigated in patients with schizophrenia. The aim of the present study among patients with schizophrenia was twofold: 1) assess the validity of the short form of the Drinking Motives Questionnaire-Revised (DMQ-R SF); and 2) investigate the relationship between drinking motives and comorbid alcohol use disorder (AUD). MethodA total of 179 patients with schizophrenia were approached to participate in the study. DSM-5 criteria were used to identify patients with comorbid AUD (AUD+; n = 42) and non-abstainers patients without comorbid AUD (AUD-; n = 71). ResultsA confirmatory factor analysis conducted on items of the DMQ-R SF for the whole sample revealed adequate goodness-of-fit values, while internal consistency indices were globally satisfactory. Group comparisons revealed higher use of alcohol and other substances, as well as stronger drinking motives among AUD + patients, while groups were comparable concerning clinical features of schizophrenia, including psychotic symptom dimensions and severity. Regression analysis showed that the Alcohol Use Disorder Identification Test score was significantly associated with two internal drinking motives: enhancement and coping. ConclusionsFindings suggest that the DMQ-R SF is a reliable tool for assessing drinking motives among patients with schizophrenia. Enhancement and coping motives seem to play a major role in comorbid AUD among these patients. Community-based and clinical treatment programs should take the drinking motives of dual-diagnosis patients into consideration, in order to improve their outcomes.

Assessing The Validity Of A Culturally Modified Drinking Motives Questionnaire For Use In Aboriginal Communities.

Introduction: Alcohol related harms disproportionately affect Aboriginal people in Australia. Motives to drink have been identified as the most proximal factor to alcohol consumption. Objectives: The aim of this study is to assess the validity of a culturally modified Drinking Motives Questionnaire-Revised (DMQ-R) (Cooper, 1994) with Aboriginal participants. Design: The study was cross sectional, utilising data collected via face-to-face surveys with a sample of adult Aboriginal participants. Participants: A convenience sample of 135 Aboriginal men (n=41) and women (n=94) from the Pilbara Region of Western Australia, who had consumed alcohol in the preceding 12 months. Outcome Measures: The Culturally modified DMQ-R (CDMQ-R) developed in consultation with Aboriginal community researchers and a local Aboriginal Community Reference Group was the primary outcome measure for this study. Results: Confirmatory Factor Analysis indicated the four-factor model of drinking motives as measured by a culturally modified DMQ-R was valid for use with Aboriginal people of the Pilbara region. Conclusions: While most items loaded on the factor solution as hypothesised, there were some minor discrepancies which suggest further modification may be needed. In addition, the reduction of the original five-point scale to a three-point scale created statistical challenges. Future research might seek to further refine the DMQ-R for this population and determine an appropriate method for expanding the response scale incorporating advice from Aboriginal people.

Reward drinking and naltrexone treatment response among young adult heavy drinkers.

Theory-driven, exploratory study to: (i) identify a reward drinking phenotype in young adults; (ii) evaluate this phenotype as a predictor of naltrexone response; and (iii) examine mechanisms of naltrexone in reward drinkers. Secondary analysis of a randomized controlled trial. USA. A total of 128 young adult (ages 18-25) heavy drinkers. Naltrexone versus placebo. Daily surveys assessed affect, urge, drinking, and context. The Drinking Motives Questionnaire was used to identify phenotypes based on reward (enhancement motives) and relief (coping motives) drinking. We identified three profiles: "Low reward/Low relief" (14.1%; low enhancement/low coping motives); "Reward drinkers" (62.2%; high enhancement/low coping motives); and "High reward/High relief" (22.7%; high enhancement/high coping motives). Among reward drinkers (versus low profile), naltrexone significantly reduced percent days drinking to intoxication (blood alcohol concentration [BAC] ≥0.08) (PDI) (d = 0.56; 95% CI [0.17, 0.96]) and percent high intensity drinking days (PHID) (8/10 drinks for women/men) (d = 0.32; 95% CI [0.01, 0.68]). Among the high reward/high relief profile drinkers (versus low profile), naltrexone reduced PHID (d = 0.69; 95% CI [0.02, 1.50]). Using profile-informed cutoffs and observed scores (for clinical applicability): (i) among cutoff-derived reward drinkers, we found a medium-to-large (d = 0.66; 95% CI [0.24, 1.16]) and small effect (d = 0.28; 95% CI [0.04, 0.72]) of naltrexone in reducing PDI and PHID, respectively; and (ii) among the cutoff-derived high reward/high relief subgroup, we found a medium-to-large effect (d = 0.63; 95% CI [0.05, 1.1]) of naltrexone in reducing PHID. Among reward drinkers (not other profiles), naltrexone reduced drinking on days a drinking event occurred by weakening the within-day association between positive affect and urges (P < 0.05). Naltrexone has pronounced effects in reducing risky drinking among young adult reward drinkers (high reward/low relief) by reducing urges on days when individuals have higher positive affect and are exposed to a drinking event. Naltrexone also appears to reduce risky drinking among young adult high reward/high relief drinkers, but not via the same mechanism.

Association of the Fatty Acid Amide Hydrolase C385A Polymorphism With Alcohol Use Severity and Coping Motives in Heavy‐Drinking Youth

Reduced function of fatty acid amide hydrolase, the catabolic enzyme for the endocannabinoid anandamide, can be inherited through a functional genetic polymorphism (FAAH rs324420, C385A, P129T). The minor (A) allele has been associated with reduced FAAH enzyme activity and increased risk for substance use disorders in adults. Whether this inherited difference in endocannabinoid metabolism relates to alcohol use disorder etiology and patterns of alcohol use in youth is unknown. To examine this question, heavy-drinking youth (n=302; mean age=19.74±1.18) were genotyped for FAAH C385A. All subjects completed a comprehensive interview assessing alcohol use patterns including the Timeline Follow-back Method, Alcohol Use Disorders Identification Test (AUDIT), and Drinking Motives Questionnaire. Analyses of Covariance (ANCOVAs) were conducted to assess differences in drinking patterns and drinking motives between genotype groups, and mediation analyses investigated whether drinking motives accounted for indirect associations of genotype with alcohol use severity. Youth with the FAAH minor allele (AC or AA genotype) reported significantly more drinking days (p=0.045), significantly more frequent heavy episodic drinking (p=0.003), and significantly higher alcohol-related problems and consumption patterns (AUDIT score p=0.045, AUDIT-C score p=0.02). Mediation analyses showed that the association of FAAH C385A with drinking outcomes was mediated by coping motives. These findings extend previous studies by suggesting that reduced endocannabinoid metabolism may be related to heavier use of alcohol in youth, prior to the onset of chronic drinking problems. Furthermore, differences in negative reinforcement-related drinking could account in part for this association.

Why do patients with chronic hepatitis C drink alcohol? An examination of pain, depression and drinking motives.

Alcohol consumption in the setting of chronic HCV is associated with accelerated progression towards cirrhosis, increased risk of hepatocellular carcinoma and higher mortality. This analysis contextualizes how sociodemographic factors, chronic pain and depression relate to the motivations of individuals with chronic HCV to consume alcohol. We conducted a secondary analysis of baseline data from the Hep ART trial of behavioural interventions on alcohol use among patients with HCV. Alcohol consumption was measured using the Drinking Motives Questionnaire and a novel 6-item measure of pain-related drinking motives. Statistical analyses performed included ANOVA for bivariate analyses and multivariable ordinary least-squares linear regression. At study baseline, 181 participants had an average age of 55years; the majority (66.7%) reported beyond-minor pain; and a third (37%) met criteria for depression; drinking motives were higher for individuals with beyond-minor pain (means 9.9 vs. 4.6, p<.001) and who met criteria for depression (means 10.9 vs. 6.4, p<.001) when using the pain-related drinking motives items. Average pain(coef=1.0410067141<.001) was significantly associated with increased motives to drink to relieve pain in the full baseline model specification controlling for all covariates using ordinary at least squares; depression (coef=7.06; 95% CI 1.32, 12.81; p=.016) was significantly associated with increased non-pain-related motives to drink. From baseline to 3-month follow-up, compared to participants who had mean average pain scores among the sample, motives to drink to relieve pain decreased in participants who had higher average pain scores (coef=-0.30; 95% CI -0.59, -0.01; p=.40). Physical pain and depression are associated with increased motives to consume alcohol. Patients with chronic liver disease should be screened for chronic pain and depression and, if present, referred to pain specialists or co-managed in partnership with pain specialists in hepatology clinics.

Daily relationships between posttraumatic stress symptoms, drinking motives, and alcohol consumption in trauma-exposed sexual minority women.

Objective: Sexual minority women (SMW) evidence elevated rates of trauma exposure, posttraumatic stress (PTS), and alcohol consumption. Self-medication models of drinking suggest that individuals may drink to cope with symptoms of PTS, but this possibility remains untested among SMW. Method: The current study used data from drinking days collected via daily diary assessments from 81 trauma-exposed SMW. Participants were mostly White (72.8%) and ranged in age from 18 to 25 (M = 23.8). Participants were followed over 2 14-consecutive-day measurement bursts (720 person-days reported). Analyses were conducted to examine whether coping drinking motives (vs. social, enhancement, and conformity drinking motives), as assessed by an adapted Drinking Motives Questionnaire, mediated the daily level relationship between PTS symptoms (assessed by the PTSD Checklist) and the number of standard drinks per drinking day. Results: Results from multilevel structural equation models indicated that day-to-day fluctuations in PTS symptoms, as well as average levels of PTS symptoms, were associated with increased coping drinking motives. Coping drinking motives, but not other drinking motives, mediated within-person associations between PTS and drinking, such that daily fluctuations in PTS symptoms were associated with stronger-than-normal coping drinking motives, which in turn predicted more drinks per drinking day. Conclusions: Results highlight the importance of coping drinking motives and suggest that alternative coping strategies may help trauma-exposed SMW to manage heightened PTS symptoms without increasing their alcohol consumption.

The Emerging Adult Reasons for Substance Use (EARS): Preliminary Support for Multidimensionality, Validity and Reliability

Introduction: Substance use peaks during the transition to adulthood, beckoning additional research on its developmental influences. This article reports initial findings on the validity and reliability of the Emerging Adult Reasons for Substance use (EARS), a new measure of substance use motives based on Arnett’s (2000) proposed emerging adult dimensions. Method: Content experts in emerging adulthood theory generated EARS items and collected data from a large online sample. We completed exploratory (EFA) and confirmatory factor analyses (CFA) on split halves of the total sample (n = 750). Then, we tested for invariance across genders and age cohorts, as well as examined cross-correlations with the Inventory of Dimensions of Emerging Adulthood (IDEA), Drinking Motives Questionnaire (DMQ-Revised), and measures of substance use. Results: The EFA identified three internally consistent factors: Normative Expectancy, Developmental Strain, and Subjective Invulnerability. Confirmatory factor analyses supported the three factor model, but fit indices were slightly below published standards (RSMEA = .82, CFI = .85, TLI = .83, SRMR = .07). For Normative Expectancy and Developmental Strain, intercepts varied across age cohorts, with higher intercepts for emerging relative to older adults. The patterns of correlations generally supported the construct validity of the EARS subscales. Conclusion: The EARS is reliable and valid, and appears to measure developmentally specific motives for substance use. Additional studies may further validate this promising instrument.

Modified Drinking Motives Questionnaire–Revised: Psychometric Validation in a Psychiatric Sample of Young Adults with Predominantly Polysubstance Use

IntroductionMeasures of motives for alcohol use provide an important avenue for understanding underlying psychological reasons that drive substance use and predict distinct patterns of use. The Modified Drinking Motives Questionnaire–Revised (MDMQ-R; Grant, Stewart, O'Connor, Blackwell, Conrod, 2007) measures five drinking motives: social, enhancement, conformity, coping-with-anxiety, and coping-with-depression. The MDMQ-R and its predecessors have previously been validated only in non-clinical normative samples. PurposeTherefore, the present study aimed to validate the factor structure and internal consistency of the MDMQ-R in a diverse psychiatric sample of substance-using young adults that presented with either exclusive alcohol use or polysubstance use. MethodParticipants were 255 substance-using young adults (18–26 years; M = 21.17) admitted to the young adult partial hospitalization treatment program at a private psychiatric hospital (62% female; 78% White; 43% students). ResultsA confirmatory factor analysis revealed that items loaded on their respective latent factors (ps < 0.01; loadings between 0.50 and 0.90; reliabilities between 0.80 and 0.94). However, goodness of fit statistics were not reflective of model fit found in Grant et al. (2007) in the overall sample, as well as in alcohol-only and polysubstance-using samples. DiscussionResults suggest that the factor structure of the MDMQ-R did not replicate in the present sample. Potential explanations and future directions are discussed in light of the results, including generalizability and clinical utility.
