Motivations for marijuana use: use and associated negative consequences.

Marijuana use has increased significantly among adolescents and young adults. It is important for prevention scientists to understand youth motivations for marijuana use in order to refine and/or create intervention to limit harm. The current study surveyed 114 marijuana using college students (67% women; 78% White) on their motivations for using marijuana, frequency of use and associated negative consequences, and theoretical and empirical influences on motivations and use. Results indicated that students most frequently endorsed enjoyment, sleep, and low-risk motivations for use. Variables associated with the Theory of Planned Behavior and Strain Theory were associated with a variety of motivations for use. Motivations, perceived behavioral control regarding marijuana, and parental active tracking were associated with frequency of use, while negative consequences were predicted by frequency of use and attitudes regarding marijuana. Researchers seeking to develop programs to prevent marijuana-related harm may benefit from focusing on the differential motivations for use observed.

First- and second-hand consequences of alcohol in college: Differential associations with later alcohol use.

INTRODUCTION: College students are at increased risk of experiencing a variety of consequences as result of their own as well as others' alcohol consumption. The current study examined the differential associations between both first-hand consequences (resulting from one's own drinking) and second-hand consequences (resulting in victimization as a result of others' drinking) and subsequent alcohol consumption across the first year of college. METHOD: First year students (n = 253) from a large northeastern U.S. university were randomly selected to participate and surveyed at the end of the first semester of college (time 1) and during the first semester of the second year of college (time 2). RESULTS: Results showed a significant, positive relationship between first-hand consequences and subsequent weekend drinking (ß = .16, p < .05) and heavy episodic drinking (ß = .49, p < .01), after controlling for individual and friend drinking. A negative association between second-hand consequences and later heavy episodic drinking was also observed (ß = -.16, p < .05). DISCUSSION AND CONCLUSIONS: The findings provided partial support for both a positive association hypothesis and a negative association hypothesis. The importance of personal alcohol consumption and peers' drinking in relation to first- and second-hand consequences are discussed.

Parental Knowledge is a Contextual Amplifier of Associations of Pubertal Maturation and Substance Use.

Earlier pubertal development and less parental knowledge have been linked to more substance use during adolescence. The present study examines interactions between pubertal timing and tempo and parental knowledge (children's disclosure, parental control, and parental solicitation) for adolescent substance initiation. Data are from a northeastern US-based cohort-sequential study examining 1023 youth (52 % female) semiannually for up to 6 assessments (ages 10.5-19 years). The findings supported the hypothesis that lower knowledge is a contextual amplifier of early timing-substance use associations in girls and later timing/slower tempo-substance use associations in boys, though results varied based on source of knowledge. The findings suggest that prevention efforts may have the greatest impact when targeting families of early developing girls, and later developing boys, and that incorporating a focus on specific sources of knowledge depending on the pubertal maturation profile of the adolescent may prove valuable in prevention/intervention efforts.

Parent-Child Discrepancies in Reports of Parental Monitoring and Their Relationship to Adolescent Alcohol-Related Behaviors.

Discrepancies between parents and adolescents regarding parenting behaviors have been hypothesized to represent a deficit in the parent-child relationship and may represent unique risk factors for poor developmental outcomes. The current study examined the predictive utility of multiple methods for characterizing discrepancies in parents' and adolescents' reports of parental monitoring on youth alcohol use behaviors in order to inform future study design and predictive modeling. Data for the current study came from a prospective investigation of alcohol initiation and progression. The analyzed sample consisted of 606 adolescents (6th-8th grade; 54 % female) and their parents were surveyed at baseline, with youth followed up 12 months later. A series of hierarchical logistic regressions were performed for each monitoring-related construct examined (parental knowledge, parental control, parental solicitation, and child disclosure). The results showed that adolescents' reports were more closely related to outcomes than parents' reports, while greater discrepancies were frequently found to be uniquely associated with greater likelihood of alcohol use behaviors. Implications for future work incorporating parents' and adolescents' reports are discussed.

Optimizing timing and dosage: does parent type moderate the effects of variations of a parent-based intervention to reduce college student drinking?

Research on parent-based interventions (PBIs) to reduce college student drinking has explored the optimal timing of delivery and dosage. The present study extended this work by examining the effectiveness of three different PBI conditions on student drinking outcomes as a function of parenting types and students' pre-college drinking patterns. Four hypotheses were evaluated (early intervention, increased dosage, invariant, and treatment matching risk). A random sample of 1,900 college students and their parents was randomized to four conditions: (1) pre-college matriculation, (2) pre-college matriculation plus booster, (3) post-college matriculation, or (4) control, and was assessed at baseline (summer prior to college) and 5-month follow-up. Baseline parent type was assessed using latent profile analysis (positive, pro-alcohol, positive, anti-alcohol, negative mother, and negative father). Student drinking patterns were classified at baseline and follow-up and included: non-drinker, weekend light drinker, weekend heavy episodic drinker, and heavy drinker. Consistent with the treatment matching risk hypothesis, results indicated parent type moderated the effects of intervention condition such that receiving the intervention prior to college was associated with lower likelihood of being in a higher-risk drinking pattern at follow-up for students with positive, anti-alcohol, or negative father parent types. The findings are discussed with respect to optimal delivery and dosage of parent-based interventions for college student drinking.

Active tracking measures: Providing targets for youth alcohol use and health behavior interventions.

This study seeks to use examine the utility of recently published, developmentally informed measures of parental active tracking for work on youth health behaviors. Information on parental active tracking and health behaviors were collected in six independent survey studies (n's = 157-408). A series of empirical questions regarding parental active tracking were examined. The recently published measures of parental active tracking in high school and college were shown to have sufficient internal consistency, to be well described by single latent factors, to be empirically distinct from helicopter parenting, to be inconsistently linked with youth risk behaviors, and to demonstrate closer linkages with youth substance use when accounting for parental motivations for tracking. The measures of parental active tracking employed provide face valid, psychometrically sound, and empirically supported indices for use examining parental influences during adolescence and young adulthood.

Moderation of a parent-based intervention on transitions in drinking: examining the role of normative perceptions and attitudes among high- and low-risk first-year college students.

BACKGROUND: Parent-based interventions (PBIs) are an effective strategy to reduce problematic drinking among first-year college students. The current study examined the extent to which student-based characteristics, derived from the Theory of Planned Behavior, moderated 3 PBI conditions: (i) prior to college matriculation (PCM); (ii) PCM with a booster during the fall semester; and (iii) after college matriculation. The moderator variables included injunctive and descriptive peer norms about alcohol use and attitudes toward alcohol use. METHODS: Using data from a randomized control trial delivered to 1,900 incoming college students, we examined differential treatment effects within 4 types of baseline student drinkers: (i) nondrinkers; (ii) weekend light drinkers (WLD); (iii) weekend heavy episodic drinkers; and (iv) heavy drinkers. The outcome variable was based on the transitions in drinking that occurred between the summer prior to college enrollment and the end of the first fall semester and distinguished between students who transitioned to 1 of the 2 risky drinking classes. RESULTS: The results indicated that injunctive norms (but not descriptive norms or attitudes) moderated the differential effects of the PBI with strongest effects for students whose parents received the booster. Differential effects also depended on baseline drinking class and were most pronounced among WLDs who were deemed "high-risk" in terms of injunctive peer norms. CONCLUSIONS: Parental influence can remain strong for young adults who are transitioning to college environments, even among students with relatively high peer influence to drink alcohol. Thus, the PBI represents an effective tool to prevent escalation of alcohol use during the first year of college, when risk is highest and patterns of alcohol use are established.

Associations between reasons to attend and late-high school dropout.

This study addressed (1) whether there were unique profiles of student self-reported reasons for attending school among 10(th) graders, (2) whether these profiles were differentially associated with late high-school dropout, and (3) whether parent characteristics differed across profiles. Using data from the Educational Longitudinal Study of 2002 (N = 15,362), five latent classes were found. The first class (49%) reported intrinsic, identified/introjected, and external motivations for attending school. The second class (32%) attended for identified/introjected and external reasons, while the third class (11%) reported intrinsic and identified/introjected reasons. The final two classes reported only identified/introjected (5%) or external (4%) motivations. Individuals in the identified/introjected and external classes were at greatest risk of dropping out between 10(th) and 12(th) grade. A host of parenting characteristics differed across class, with students in the intrinsic-identified/introjected-external class displaying the most favorable pattern of results. Implications for dropout prevention and academic promotion programs are discussed.

Perceptions of control and disordered eating behaviors during college transitions.

ObjectivesDisordered eating behaviors are prevalent among college-age individuals. Issues of control (e.g., perceptions of control; desire for control) are often salient for these individuals. Concerns regarding control can be exacerbated during transitions. The current study examined the extent to which disordered eating behaviors in college were predicted by locus of control, desire for control, and their interaction. We also explored whether these associations might be impacted by student life transitions (e.g., into/out of college). Participants and methods: A sample of 156 college students (72% women) was surveyed. Results: Both locus of and desire for control were predictive of disordered eating, but hypothesized moderations among locus of control, desire for control, and life transitions were primarily not supported. Conclusions: Issues surrounding perceptions of control are important for disordered eating treatments or prevention programs, while more research is needed on the role life transitions may play in exacerbating risk.

Parental active tracking measures and health behaviors during high school and college.

Objective: This study developed and tested new measures of youth perceptions of parental active efforts to track their activities during adolescence and college. Participants and Methods: Between March and October 2016, a sample of 314 college students aged 18-25 completed a survey including their perceptions of their parent's active tracking efforts during high school and college. Items were then analyzed, and internally consistent measures were derived. Results: The new measures demonstrated significant convergent validity with the three sources of parental knowledge constructs (parental solicitation, parental control, and youth disclosure). Greater perceived parental active tracking efforts during adolescence and in college were associated with better health behaviors in both time periods. Conclusions: The newly derived measures represent appropriate and predictive indices of parental tracking behaviors during adolescence and college, designed specifically with these populations in mind, to be used in pre-intervention and intervention work with parents.

Parenting, health, and use of medications among college youth: The PHARMACY survey study.

Prescription medication misuse represents a major public health concern, with high rates of negative consequences observed among youth. The current study examines the potential roles parents can play in mitigating youth prescription-related harm, with a particular focus on opioid and antibiotic safety. A sample of 167 students from a mid-sized college in the Northeast U.S. were surveyed on their prescription medication knowledge, comfort, and behaviors and perceptions of their parents' behaviors. Results showed that parenting behaviors like targeted discussions on prescription medication safety (e.g., proper disposal of excess medication) were associated with greater medication-related comfort, which, in turn, was associated with safer prescription medication behaviors.

Profiles of family routines during adolescence associated with profiles of health behaviors in young adulthood.

This study examined associations between profiles of family routines in early adolescence and profiles of health behaviors during young adulthood. In a sample of 4565 individuals, latent transition analysis indicated individuals in a family characterized by low involvement in adolescence were most likely, across classes, to demonstrate a profile characterized by substance use in young adulthood. The high-involvement class during adolescence was least likely to be a substance user but was relatively likely to be in the poor diet and exercise class during young adulthood. Results highlight the utility of examining complex family influences on health using person-centered methods.

Reasons to have sex, personal goals, and sexual behavior during the transition to college.

Emerging adults (M = 18.99 years, SD = .50) completed cross-sectional questionnaires (N = 943) and targeted follow-up telephone surveys (N = 202) across the transition to college. Gender, personal goals (dating, friendship, academic), and past sexual behavior were examined as predictors of reasons to have and not to have sex. Men rated Self-focused reasons to have sex as more important; women rated Partner-focused reasons to have sex and Ethical reasons not to have sex as more important. Importance of Pregnancy/STD reasons not to have sex did not differ by gender. Before college entrance, sexual history and personal goals predicted endorsement of reasons for/against sex. Personal goals predicted first intercourse during freshman year. Limitations of the study include the single university sample and use of closed-ended self-report measures. Personal goals and reasons for/against sex are associated with sexual behavior and should be addressed in programs designed to promote sexual health among emerging adult college students.

Trajectories and correlates of reasons for abstaining or limiting drinking during adolescence.

INTRODUCTION: Our aim was to enhance understanding of the trajectory of reasons for abstaining and limiting drinking (RALD) over the course of adolescence and how RALD levels or trajectories may differ based on lifetime experience with alcohol and/or gender. METHODS: Participants were 1023 middle school students (52% female) who completed online surveys at baseline and five follow-ups over a 3-year period, assessing lifetime sip and full drink of alcohol and RALD. Hierarchical linear models were used to estimate change over time in total RALD and RALD subscales (upbringing, performance/control). Between-person (gender and drinking status) correlates of average RALD and change in RALD over time were considered. RESULTS: RALD total and subscale scores significantly decreased over time (ages 10.5-16.5). Drinking experience in both milestones (sip, full drink) was found to be a significant moderator of change in RALD over time; decline was fastest among adolescents reporting lifetime experience with drinking. Boys reported lower RALD, though the pace of change in RALD across time did not differ by gender. CONCLUSIONS: This was the first study to report prospective changes in the cognitive domain of RALD among young adolescents. That change over time in RALD is moderated by drinking experience suggests an increased risk among those with earlier drinking experience. Findings highlight the importance of considering sipping, not just consumption of a full drink, as a pivotal developmental milestone. Prevention efforts that target RALD are implicated and parent-based intervention strategies may be beneficial.

Trajectories of alcohol use and consequences in college women with and without depressed mood.

College students with depressed mood face heightened risk for experiencing drinking-related negative consequences. However, few studies have examined prospective patterns of alcohol consequences among depressed students. In the present investigation, we assessed how first-year college women's trajectories of heavy episodic drinking (HED) and alcohol consequences differed as a function of depressed mood at college entry. Participants were 233 heavy drinking incoming first-year college females (61% White) at a mid-sized West Coast University. Participants completed an online baseline survey, attended a single brief group intervention session, and completed 1- and 6-month post-intervention follow-up surveys. Depressed mood, alcohol consumption, and alcohol consequences were assessed at each time point. We employed latent growth curve analyses. Females with depressed mood, versus without depressed mood, experienced greater levels of alcohol consequences overall, particularly during transitions to college. However, contrary to hypotheses, participants with depressed mood (vs. without) exhibited significantly steeper declining trends in consequences, controlling for treatment condition, age, race, and ethnicity, and despite stable drinking levels, depressed mood, and use of protective behaviors over time. Potential explanations and suggestions for future research are discussed.

Contextual influences on early drinking: Characteristics of drinking and nondrinking days.

Research characterizing the adolescent drinking context is limited, often relies on samples of current drinkers reporting on recent/last or typical drinking experiences, and provides little information about the context of very early use. The present study uses repeated monthly assessments to describe the context of drinking days and matched nondrinking days to determine the unique risk associated with different drinking-related characteristics. Additionally, we used latent class analysis to empirically identify key configurations of drinking-related characteristics and both family- and nonfamily-related environmental characteristics (social context, physical location, source of alcohol). Data included 688 days (344 drinking days, 344 nondrinking days) from 164 middle-school students enrolled in a prospective study on drinking initiation and progression (62% female; 26% non-White, 11% Hispanic). Results supported 4 patterns: (a) heavier drinking occurring in a peer context, lighter drinking occurring in (b) a family context or (c) a peer context, and (d) drinking alcohol obtained at home without permission. Latent classes varied as a function of gender, age, peer norms, and parenting behaviors as well as alcohol type and perceived alcohol availability. Findings indicated that highly endorsed contexts were not necessarily the riskiest ones, and simply targeting an oft-reported source of alcohol, physical location, or social context may not be an effective strategy for reducing underage drinking. Additionally, although greater monitoring and anticipated parent reaction to drinking are typically protective against adolescent drinking, we found they were associated with parent-sanctioned drinking, suggesting the role of parenting practices must be considered in the context of drinking pattern.

Trajectories of Adolescent Alcohol Use in the Year Following a Brief Alcohol Intervention.

OBJECTIVE: Brief interventions have become increasingly popular for youth who engage in problematic drinking behavior. The purpose of this study was to examine the alcohol use trajectories of adolescents over a 12-month period following the receipt of a brief intervention. METHOD: The current sample came from two independent studies and consisted of 206 adolescents (ages 13-19; 52% male) recruited through an emergency department or community institution (e.g., courts, schools). Timeline followback methods were used at four points over 1 year to obtain daily estimates of alcohol use behaviors, with daily data then aggregated at the monthly level to examine trajectories of total drinks consumed and maximum drinks on one occasion. Using latent growth curve analysis, we expected a general pattern of increasing use over time, with lower use during the month immediately following completion of the intervention. RESULTS: Models with random intercepts, random linear slopes, and fixed quadratic trends provided good fit to the data for both total drinks and maximum drinks. For each outcome, there was an immediate decrease and then a gradual increase up to the 3- and 6-month assessments, with decreases seen in the months following assessments. Older age, White race, non-Hispanic ethnicity, and greater prior substance use were associated with greater initial levels of use and growth over time. CONCLUSIONS: Interindividual differences were observed in alcohol use trajectories over time for high-risk adolescents following an alcohol use intervention. Subsequent research may demonstrate more uniform and permanent modification of trajectories by incorporating intervention-related materials into follow-up contacts.

Prevalence and correlates of sipping alcohol in a prospective middle school sample.

Research documents an association between early use of alcohol and adverse outcomes. Most studies on drinking initiation exclude sipping or confound sips with consumption of a full drink. However, even a few sips of alcohol can constitute a meaningful experience for naïve drinkers. Prior research with this project indicated that sipping before middle school predicted subsequent adverse outcomes (at high-school entry), even controlling for child externalizing and sensation seeking and parent alcohol use. The present study extends our prior work by examining the correlates of early sipping and sipping onset. The sample was comprised of 1,023 6th, 7th, and 8th graders (52% female; 24% non-White, and 12% Hispanic). Participants completed Web-based surveys on 5 occasions over the course of 2 years. The prevalence of sipping at Wave 1 was 37%, with 29% of never-sippers initiating sipping within 2 years. Sipping was associated with stronger alcohol-related cognitions and low school engagement as well as contextual influences in the peer, sibling, and parent domains. Sipping onset among never-sippers was prospectively predicted by sensation seeking and problem behavior as well as parental and sibling influences. More important, mere availability of alcohol was a strong correlate both concurrently and prospectively. Further analyses demonstrated that youth who sipped alcohol with parental permission had a lower profile of risk and healthier relationships with parents as compared with youth who reported unsanctioned sipping. Findings point to the importance of considering fine-grained early drinking behavior and call for further attention to sipping in research on initiation of alcohol use.
