A confirmatory factor analysis of a revised motives for playing drinking games (MPDG-33) scale among university students in the United States.

AIM: Participating in a drinking game (DG) is common practice among university students and can increase students' risk for heavy drinking. Given the theoretical link between motivations to drink and alcohol use, careful consideration should be given to students' motivations to play DGs. In this study, we examined the factor structure, internal consistency, and concurrent validity of a revised version of the motives for playing drinking games (MPDG) scale, the MPDG-33. METHODS: University students (n = 3345, Mage = 19.77 years, SDage = 1.53; 68.8% = women; 59.6% = White) from 12 U.S. universities completed a confidential online self-report survey that included the MPDG-33 and questions regarding their frequency of DG participation and typical drink consumption while playing DGs. RESULTS: Confirmatory factor analysis indicated the 7-factor model fit the data adequately, and all items had statistically significant factor loadings on their predicted factor. All subscales had adequate to excellent internal consistency and were positively correlated with the frequency of DG participation and the typical number of drinks consumed while playing DGs (though the correlations were small). CONCLUSION: Findings suggest that the MPDG-33 can be reliably used in research and clinical settings to assess U.S. university students' motives for playing DGs.

Alcohol Use Predicts Longer But More Fragmented Sleep: A Daily Diary Study of Alcohol, Sleep, and PTSD in Nurses.

BACKGROUND: Due to the demanding nature of their profession, nurses are at risk of experiencing irregular sleep patterns, substance use, and fatigue. Evidence supports a reciprocal relationship between alcohol use and sleep disturbances; however, no research has examined such a link in a sample of nurses. One factor that may further impact the dynamic between alcohol and sleep patterns is posttraumatic stress disorder (PTSD) symptoms. We investigated the daily bidirectional associations between alcohol use and several sleep domains (i.e., self-report and actigraphy-determined sleep), and moderation by baseline PTSD symptom severity. METHOD: Over a 14-day period, 392 nurses (92% female; 78% White) completed sleep diaries and actigraphy to assess alcohol use and sleep patterns. Within-person bidirectional associations between alcohol and sleep were examined using multilevel models, with symptoms of PTSD as a cross-level moderator. RESULTS: Daily alcohol use (i.e., ≥ 1 alcoholic beverage; 25.76%) was associated with shorter self-reported sleep onset latency (b = -4.21, p = .003) but longer self-reported wake after sleep onset (b = 2.36, p = .009). Additionally, days with any alcohol use were associated with longer self-reported sleep duration (b = 15.60, p = .006) and actigraphy-determined sleep duration (b = 10.06, p = .037). No sleep variables were associated with next-day alcohol use. Bidirectional associations between alcohol consumption and sleep were similar regardless of baseline PTSD symptoms. CONCLUSION: Our results suggested that on days when nurses drank alcohol, they experienced longer but also more fragmented sleep.

Examining the Factor Structure and Correlates of Motives to Drink Before Attending a Virtual Social Event During COVID-19 Among University Students.

Background: Many university students pregame or drink before a social event. Pregaming carries some risk due to its link to heavy drinking. During the COVID-19 pandemic, there was limited access to many drinking venues (e.g., bars/clubs). Moreover, universities shifted to a virtual format and imposed restrictions on in-person gatherings resulting in the reliance on virtual platforms for class instruction, meetings, and social events. The pandemic facilitated changes in students' drinking behaviors, stress levels, and how they maintained social contact with others. Thus, it is conceivable that during an academic pandemic year, students may have engaged in the act of drinking before attending a virtual social event. Objectives: In the present study, we examined the factor structures/item loadings of the Pregaming Motives Measure-Virtual (PGMM-V) among students (N = 283; Mage = 21.38; women = 69.3%; White = 45.4%, Hispanic = 40.8%) from seven universities who completed an online questionnaire (Spring/Summer-2021). Items from the original Pregaming Motives Measure (Bachrach et al., 2012) were modified to reflect motives to drink before attending a virtual social event. Results: We found evidence for a 2-factor structure model of the PGMM-V which includes social/enhancement and social ease/stress. Bivariate correlations indicated that social/enhancement and social ease/stress were (a) positively associated with frequency of drinking and alcohol consumption prior to attending virtual social events, and (b) general drinking motives (social/enhancement/coping) that align with these motives. Conclusions: The PGMM-V is a promising instrument that could be used in future research designed to understand students' pregaming behaviors for virtual social events as the use of such platforms are increasingly relied upon for social engagement.

Effects of anxiety sensitivity on cannabis, alcohol, and nicotine use among adolescents: evaluating pathways through anxiety, withdrawal symptoms, and coping motives.

Anxiety sensitivity (AS) is a promising intervention target due to its relevance to negative health behaviors broadly, and substance use specifically. The aim of the current study was to evaluate the direct and indirect pathways through which elevated AS could relate to recent substance use among a national adolescent sample recruited via social-media. As predicted, AS was indirectly associated with greater likelihood of using alcohol, cigarettes, and electronic nicotine delivery systems in the past-month through anxiety symptoms. Regarding cannabis, AS was directly related to increased likelihood of past-month cannabis use; however, the indirect relation between AS and likelihood of past-month use via anxiety symptoms was not significant. Through chained indirect effects, AS was related positively to past-month alcohol and cannabis use via anxiety symptoms and coping-related motives, and through withdrawal symptoms and coping-related motives. Study findings can be used to generate hypotheses on potential pathways through which AS could prospectively relate to substance use among youth.

Greater adolescent tiredness is related to more emotional arousal during a hyperventilation task: An area under the curve approach.

INTRODUCTION: Approximately 36% of adolescents report sleep problems (Crowley et al., 2018). Understanding the relation between sleep and emotional experience is crucial in understanding the high incidence of mental health concerns during adolescence. The current study sought to expand understanding in the area by testing the hypothesis that baseline tiredness ratings would predict greater emotional arousal and negative valence across the course of emotional response elicited by a voluntary hyperventilation procedure. METHODS: A community sample of 110 youth (10-18 years; 47.8% girls) provided baseline tiredness ratings and ratings of emotional valence and arousal, 2 min before, immediately after, and 3 min after a hyperventilation task. The area under the curve (AUC) was calculated using the repeated measures of valence and arousal, and correlations between the response curves and baseline tiredness were examined. RESULTS AND CONCLUSIONS: Findings indicated baseline tiredness was positively associated with AUC arousal (r = 0.23), but not valence. This suggests daytime tiredness is associated with the degree of emotional arousal elicited by a psychobiological stressor. By extension, adolescents may experience more arousing emotional reactions when tired, and thus the common sleep deprivation observed during this developmental period may increase risk for mental health problems associated with elevated emotional reactivity.

Heterogeneous Patterns of Marijuana Use Motives Using Latent Profile Analysis.

Background: Given that marijuana use is often associated with detrimental physical and mental health problems, research examining motives for its use is critical for effective remedial and preventive treatment. To date, the majority of research on marijuana use motives has used variable-centered analyses, which overlooks potentially meaningful heterogeneous response patterns and the associations of those patterns with other risk/protective factors. Methods: To address this gap, in the current study, we conducted a person-centered analysis (latent profile analysis) to identify subgroups of participants based on endorsed marijuana use motives, and examined the construct validity of the optimal class solution (covariates included sociodemographic (e.g., age), psychiatric (e.g., depression), and marijuana-use indices (e.g., use-frequency, use-related problems). Participants were 898 college students (Mage = 20.93, SDage = 3.10; 68.9% female) who completed an anonymous online survey examining substance use and psychological well-being, were 18 years or older, and endorsed lifetime marijuana use. Data were collected November 2016 through February 2018. Results: Results identified four unique classes of coping, conformity, social, and enhancement marijuana use motives: (a) "Low Motives" (37.6%), (b) "High Conformity" (4.9%), (c) "Low Conformity" (45.8%), and (d) "High Motives" (11.7%). In terms of covariates, higher motive classes tended to report more frequent and problematic use. The two classes uniquely characterized by conformity motives only differed on past-month marijuana use frequency. Conclusions/Importance: The current findings provide evidence that specific classes of motives were not only associated with marijuana use frequency and problems but other risk and protective factors, such as anxiety sensitivity and social support.

Heterogeneity in the Co-occurrence of Substance Use and Posttraumatic Stress Disorder: A Latent Class Analysis Approach.

Objective: Posttraumatic stress disorder (PTSD) often co-occurs with substance use (SU). Although there has been independent research on subgroups of participants based on their PTSD or SU responses, rarely are PTSD-SU typologies examined consistent with a precision medicine approach (and corresponding person-centered statistical approaches). The current study examined the nature and construct validity (covariates of depression, physical aggression, verbal aggression, anger, hostility, reckless and self-destructive behaviors [RSDB]) of the best-fitting latent class solution in categorizing participants based on PTSD (PTSD Checklist for DSM-5) and alcohol/drug use responses (Alcohol Use and Disorders Identification Test Alcohol Consumption Questions, Drug Abuse Screening Test). Methods: The sample included 375 trauma-exposed participants recruited from Amazon's Mechanical Turk online labor market. Results: Latent class analyses indicated an optimal three-class solution (low PTSD/SU, moderate PTSD/drug and high alcohol, and high PTSD/SU). Multinomial logistic regressions indicated that depression (OR = 1.22) and frequency of RSDBs (OR = 1.20) were significant predictors of the moderate PTSD/drug and high alcohol class versus the low PTSD/SU class. Depression (OR = 1.55) and frequency of RSDBs (OR = 1.19) were significant predictors of the high PTSD/SU class versus the low PTSD/SU class. Only depression (OR = 1.27) was a significant predictor of the high PTSD/SU class versus the moderate PTSD/drug and high alcohol class. Conclusions: Results provide construct validity support for three meaningful latent classes with unique relations with depression and RSDBs. These findings improve our understanding of heterogeneous PTSD-SU comorbidity patterns and highlight acknowledgment of such subtyping (subgrouping) in considering differential treatment options, treatment effectiveness, and resource allocation.

Violent interpersonal trauma predicts aggressive thoughts and behaviors towards self and others: findings from the National Comorbidity Survey-Adolescent Supplement.

PURPOSE: The purpose of the current study is to examine the relation between adolescent traumatic event exposure and aggression directed towards the self and others. Theoretical perspectives underscore the particularly pernicious effects of violent traumas intentionally perpetrated by others in terms of negative posttraumatic outcomes. However, a careful comparison of trauma type in relation to aggression has not been done with youth. The current project, therefore, examined differences between youth with a history of violent interpersonal trauma (VIT) compared to those with a non-violent trauma type history in terms of aggressive behavior directed towards others as well as aggressive self-directed thoughts (suicidal ideation). METHOD: The sample was drawn from the National Comorbidity Survey-Replication and consisted of 1928 adolescents (M = 15.4; SD = 1.47 years), each assigned to one of four age- and gender-matched trauma history groups. RESULTS: Consistent with hypotheses, among trauma-exposed youth, those who had experienced or witnessed a VIT (compared to those reporting a non-VIT only) evidenced elevated aggression, even after controlling for a number of theoretically relevant covariates (e.g., gender, age, household income, demographic factors). CONCLUSION: Results indicate that youth with a history of VIT may be at unique risk for experiencing aggression directed towards others and the self compared to those without this specific trauma history. This is important because trauma type is an easily assessed indicator of potentially elevated risk for these types of deleterious outcomes. Findings are situated in a research agenda aimed at continuing to refine our understanding of the link between interpersonal trauma and aggression.

Perceived control of anxiety as a moderator in the relationship between anxiety sensitivity and problematic alcohol use among adolescents.

The current study examined perceived control over anxiety as a moderator in the relationship between AS and (1) alcohol use frequency and (2) binge drinking frequency among 80 community-recruited adolescents (Mage = 15.40; 40% female). Eighty-five percent of adolescents reported consuming an alcohol beverage, while 39.5% reported binge drinking. Results indicated significant interactions between AS and perceived control. More specifically, when perceived control was low, higher anxiety sensitivity was related to increased frequency of alcohol use days, but not with binge drinking days. Alternatively, when perceived control over anxiety was high, elevated anxiety sensitivity was associated with a decreased in binge drinking days, but not with alcohol use days. Findings suggest that influence of perceived control over anxiety may be another important, malleable factor that should be considered in future etiological and intervention-oriented work targeting anxiety sensitivity and alcohol misuse among adolescence.

Dimensions of parenting among mothers and fathers in relation to social anxiety among female adolescents.

Social anxiety is the most common anxiety disorder among youth; theoretical and empirical work suggest specific parenting behaviors may be relevant. However, findings are inconsistent, particularly in terms of maternal as compared to paternal effects. In the current study, we evaluated the indirect effects of perceived psychological control on the relation between anxious rearing behaviors and child social anxiety among 112 community-recruited girls (ages 12-15 years). In addition to self-report, adolescent participants completed a laboratory-based social stress task. In line with hypotheses, results indicated indirect effects of psychological control on the relation between anxious rearing behaviors and child social anxiety in maternal but not paternal models. Findings are discussed in terms of their theoretical and empirical implications for clarifying the role of parental relations in adolescent social anxiety.
