RESUMO
There is evidence for intergenerational transmission of substance use and disorder. However, it is unclear whether separation from a parent with substance use disorder (SUD) moderates intergenerational transmission, and no studies have tested this question across three generations. In a three-generation study of families oversampled for familial SUD, we tested whether separation between father (G1; first generation) and child (G2; second generation) moderated the effect of G1 father SUDs on G2 child SUDs. We also tested whether separation between father (G2) and child (G3; third generation) moderated the effect of G2 SUDs on G3 drinking. Finally, we tested whether G1-G2 or G2-G3 separation moderated the mediated effect of G1 SUDs on G3 drinking through G2 SUDs. G1 father-G2 child separation moderated intergenerational transmission. In families with G1-G2 separation, there were no significant effects of father SUD on G2 SUD or G3 drinking. However, in nonseparated families, greater G1 father SUDs predicted heightened G2 SUDs and G3 grandchild drinking. In nonseparated families, G1 father SUDs significantly predicted G2 SUDs, which predicted G3 drinking. However, G2-G3 separation predicted heightened G3 drinking regardless of G2 and G1 SUDs. Parental separation may introduce risk for SUDs and drinking among youth with lower familial risk.

Background: Simultaneous alcohol and cannabis use is associated with negative outcomes, yet little is known about what motivates the decision of simultaneous use. One possibility is that early-episode subjective effects motivate simultaneous use to complement or replace the first substance's effects. The current study used a hypothetical decision-making task to test this hypothesis. Objectives: College students (N = 486) were presented eight scenarios characterized by alcohol/cannabis subjective effects (i.e., high/low arousal positive [e.g., excited, relaxed], high/low arousal negative [e.g., aggressive, dizzy]) and asked their likelihood of simultaneously using the other substance per scenario. Multilevel modeling tested whether subjective effect scenarios predicted a higher likelihood of simultaneous use and whether ordering moderated this association. Results: Task-based simultaneous use likelihood was associated with self-reported simultaneous use, showing task validity. Scenarios characterized by high/low arousal positive effects were associated with higher likelihood of simultaneous use, whereas high/low arousal negative scenarios were associated with lower likelihood. Alcohol vs. cannabis-first scenarios were associated with higher likelihood of simultaneous use, and significant interactions were observed for high/low arousal positive and high arousal negative effects. High arousal positive scenarios were associated with higher likelihood of simultaneous use when cannabis was used first, low arousal positive scenarios with higher likelihood when alcohol was used first, and high arousal negative scenarios with lower likelihood when cannabis was used first. Conclusions: Beginning-of-episode subjective substance effects may be a promising event-level predictor of simultaneous use, and just-in-time interventions may benefit from targeting the ordering and subjective experiences of alcohol and cannabis use.

Research suggests that parental substance use disorder is associated with adolescent drinking indirectly through negative urgency, a form of impulsivity that is particularly associated with high-risk drinking. Moreover, childhood mechanisms of risk may play a role in this developmental chain such that childhood temperament and parenting may be mechanisms through which parental substance use disorder is associated with adolescent negative urgency and drinking behavior. Therefore, the current study tested whether parental substance use disorder was indirectly associated with adolescent drinking frequency through childhood temperament (i.e., "dysregulated irritability") and adolescent negative urgency, and whether relations differed by levels of maternal support and consistency of discipline. Data come from a multigenerational, longitudinal study of familial substance use disorder (N = 276, Mage in childhood = 6.28 (SD = 1.16), Mage in adolescence = 15.86 (SD = 1.56), 45.3% female). Findings indicated that parental substance use disorder indirectly predicted adolescent drinking through both childhood dysregulated irritability and adolescent negative urgency (mediated pathways). This indirect relation was stronger at higher vs. lower levels of maternal support but did not vary by maternal consistency of discipline. Parental substance use disorder also indirectly predicted adolescent drinking separately through childhood dysregulated irritability and negative urgency. Findings thus suggest that childhood dysregulated irritability may be an early marker of risk toward high-risk personality traits and behavior in adolescence that are associated with having a parental history of substance use disorder. Findings also suggest that increased maternal support may only be helpful in buffering risk for those with low levels of dysregulated irritability. Prevention efforts focused on childhood emotion regulation and emotion-based action may be useful in preventing adolescent risk behavior.

The aim of the present study was to conduct a preliminary investigation of the associations between facets of impulsivity and alcohol outcomes through motives for drinking responsibly described by self-determination theory among college students. Participants (N=2,808) were part of a multisite investigation of college student drinking across 10 universities in 8 states in the U.S. who reported past-month drinking. Results of a structural equation model testing all possible indirect associations simultaneously indicated that one-third (20 out of 60) of the indirect associations were statistically significant (p<.01). Facets with higher scores representing higher impulsivity (negative/positive urgency) were negatively associated with more internalized motives (autonomous motivation and introjected regulation) and positively associated with less internalized motives (external regulation and amotivation) for drinking responsibly. Facets with higher scores representing lower impulsivity (perseverance and premeditation) demonstrated opposite patterns of associations with motives for drinking responsibly. In turn, more internalized motives were related to higher frequency of protective behavioral strategies use, lower alcohol use severity, and fewer negative alcohol-related consequences; less internalized motives demonstrated an opposite pattern of associations with these alcohol outcomes. The present findings should be replicated using experimental and longitudinal studies for appropriately testing mediation but offer support for a novel hypothesis for motivational pathways from impulsivity to alcohol outcomes that may provide insight into intervention targets.
RESUMO
OBJECTIVE: Reductions in substance involvement into adulthood are thought to represent a normative maturing out of substance use. However, patterns and predictors of maturing out of alcohol and cannabis co-use remain largely unstudied. Therefore, the current study tested developmental trajectories of alcohol and cannabis use from late adolescence into adulthood and whether late adolescent personality traits predicted trajectory class membership. METHODS: Data come from a longitudinal study of family history of alcohol disorder (N = 458). Age bands were created to model trajectories of drinking quantity, negative alcohol consequences, and cannabis use frequency from late adolescence (age 18-22) to young adulthood (age 23-28) and adulthood (age 29-36). Participants reported on their sensation seeking, conscientiousness, and neuroticism during late adolescence and their typical drinking quantity, negative alcohol consequences, and cannabis use frequency at each age band. RESULTS: Three trajectory classes were derived from an initial Parallel Process Growth Mixture Model: (1) low-risk maturing out of alcohol-only use, (2) high-risk maturing out of co-use, and (3) high-risk switchers who increased their cannabis use into adulthood. Late adolescent sensation seeking was associated with higher odds of being in both co-use trajectories, whereas a lack of conscientiousness was associated with higher odds of being a co-use switcher. CONCLUSIONS: We identified heterogeneity in trajectories of co-use, which suggests that a lack of maturing out of alcohol involvement may be accompanied by increased cannabis use. Moreover, late adolescent personality traits may predispose individuals toward riskier developmental trajectories of substance use into adulthood.

OBJECTIVE: Naltrexone is an effective treatment for heavy drinking among young adults. Laboratory-based studies have shown that naltrexone dampens the subjective response to alcohol and craving. However, few studies have tested naltrexone's dynamic, within-person effects on subjective response and craving among young adults in natural drinking environments. METHODS: Using daily diary data from a randomized, placebo-controlled study of naltrexone's efficacy in young adults, we examined the between-person effects of treatment condition (i.e., naltrexone vs. placebo) and medication dosage (i.e., daily, targeted, and daily + targeted) on the subjective response to alcohol and craving on drinking days. Multilevel mediation models predicted subjective response and craving from treatment condition (between-person) and medication dosage (within-person), accounting for drinking levels. All effects were disaggregated within and between persons. RESULTS: At the between-person level, naltrexone directly blunted intense subjective effects (i.e., "impaired", "drunk") and indirectly blunted subjective effects through reduced drinking. Naltrexone was not associated with craving. Between-person effects were not significant after alpha correction, but their effect sizes (bs = 0.14 to 0.17) exceeded the smallest effect size of interest. At the within-person level, taking two (vs. 1) pills was associated with heavier drinking, and taking one (vs. 0) pill was associated with lighter drinking, and lighter drinking was associated with a lower subjective response and craving. Treatment condition did not moderate the within-person effects of dosing on outcomes. CONCLUSIONS: Our findings suggest that the direct between-person effect of naltrexone was largest on intense subjective responses, blunting feelings of being "drunk" and "impaired". Future research using momentary (rather than daily) assessments could confirm and extend these findings.

AIMS: Alcohol expectancies are directly linked to alcohol misuse and indirectly linked to negative consequences via use. Likewise, willingness to experience negative consequences imparts direct risk for negative consequences and may represent an important individual difference when predicting risky alcohol use. To date, no studies have examined how willingness to experience consequences may moderate relations between expectancies and alcohol use in the prediction of negative consequences. It is possible that those who expect appetitive effects and are high in willingness may discount the severity of negative consequences and drink more to realize positive expectations. Alternatively, those who expect aversive alcohol-related effects and are high in willingness may drink more to overcome negative experiences. METHODS: The current study tested these hypotheses in a sample of undergraduate students (N = 657) from a larger study focused on alcohol and cannabis co-use. RESULTS: Findings suggested that high-arousal positive expectancies (e.g. sociable, lively, talkative) function as a risk factor for negative consequences indirectly through heavier drinking, whereas low-arousal positive (e.g. mellow, relaxed) expectancies served as an indirect protective factor against negative consequences through lighter drinking. Willingness to experience negative consequences had direct and indirect effects on negative consequences through drinking but did not interact with alcohol expectancies. CONCLUSIONS: The present study demonstrates the utility of assessing the full range of alcohol expectancies and behavioral willingness in continued research into the dynamic nature of antecedents to alcohol misuse and negative consequences.

Theory suggests that behavioral undercontrol mediates the effect of parental substance disorder on offspring substance use, but no studies have tested multidimensional impulsive personality traits as mechanisms of risk. Adolescents (N = 392; 48% female) from a multigenerational study of familial alcohol disorder self-reported impulsive personality traits via the UPPS-P (Mage = 16.09; Range = 13-19) and alcohol/cannabis frequency one year later. The UPPS-P assesses negative and positive urgency (i.e., rash action in a negative or positive mood state), lack of premeditation (i.e., lack of planning/forethought), lack of perseverance (i.e., inability to finish tedious/boring tasks), and sensation seeking (i.e., thrill seeking/risk taking). Parent substance disorder was assessed via diagnostic interviews. Two-part hurdle models tested predictors of any substance use (i.e., binary part) and frequency of use (i.e., continuous part). Parent substance disorder was indirectly associated with any alcohol/cannabis use (binary part) and higher cannabis frequency (continuous part) through negative urgency. Parental substance disorder was associated with higher alcohol frequency through a lack of premeditation. Sensation seeking was associated with any alcohol/cannabis use but unrelated to parental substance disorder. Despite indirect effects, strong effects of parental substance disorder on substance use remained. The findings are discussed in terms of theory and public health implications.

BACKGROUND: Alcohol consistently impairs response inhibition in the laboratory, and alcohol impairment of response inhibition may lead to excess consumption or increases in intoxicated risk behavior, both of which contribute to risk for alcohol-related problems. To our knowledge, no prior studies have examined relations between alcohol impairment of response inhibition and either impaired control over alcohol (i.e., inability to adhere to predetermined drinking limits) or real-world alcohol-related problems. The current study addressed this gap in the literature. METHODS: Young adult social drinkers (N = 215, 76% male) participated in a between-subjects, placebo-controlled alcohol challenge study and completed self-reports approximately 2 weeks later. Multilevel models were used to examine the hypothesis that alcohol impairment of response inhibition would indirectly lead to alcohol-related problems through impaired control over alcohol use. RESULTS: Greater alcohol-induced impairment of response inhibition and impaired control over alcohol use were both significant predictors of alcohol-related problems. However, greater alcohol-induced response inhibition was not a significant predictor of impaired control over alcohol use. CONCLUSIONS: To our knowledge, this is the first study demonstrating relationships between alcohol impairment of response inhibition and real-world alcohol-related problems and the first to address relationships between alcohol impairment of response inhibition and impaired control over alcohol use. These results suggest that impaired control over alcohol use may result from deficits in the trait ability to control behavior rather than deficits in alcohol-induced response inhibition. Regardless, results suggest that alcohol impairment of response inhibition and impaired control over alcohol are both worthwhile intervention targets.

BACKGROUND: Parental drinking and parent alcohol use disorder (AUD) are known predictors of adolescent positive alcohol expectancies, but their link to negative expectancies is unclear. Research suggests that parent drinking may indirectly predict adolescent expectancies through exposure to parental drinking events. However, exposure to parent negative alcohol consequences may be more relevant to adolescents' expectancies. The present study tested the mediating effect of parent observable negative alcohol consequences in the association between parent AUD and adolescent expectancies. METHODS: This study used parent and adolescent data from the Adult and Family Development Project. A total of 581 adolescents reported on their alcohol expectancies across 2 waves of data, and their parents reported on potentially observable alcohol-related negative consequences during the first wave. Past-year and lifetime parent AUD were assessed with diagnostic interviews across 6 waves of data. RESULTS: Mothers' observable consequences mediated the effect of her past-year AUD on adolescent negative expectancies in adolescence, but this effect did not hold at a 1.5-year follow-up. Mothers' lifetime AUD was the only prospective predictor of later adolescent negative expectancies. No father drinking variables predicted expectancies, and all models were invariant across child biological sex. Finally, older adolescent age prospectively predicted higher positive expectancies, whereas the adolescents' own drinking predicted lower negative expectancies. CONCLUSIONS: These findings, in line with other recent studies, suggest that exposure to mothers' negative experiences with alcohol may counterintuitively normalize negative alcohol effects. This may paradoxically increase risk for adolescents rather than buffering the effects of a family history of parental AUD.

Parenting during early adolescence is key in protecting adolescents against substance use initiation and patterned use. Parental alcohol use disorder is a robust risk factor for maladaptive parenting and adolescent alcohol use. However, it is unclear what effect parent prescription opioid misuse has on parenting and adolescent alcohol use. Associations were examined among parent alcohol use disorder, prescription opioid misuse, and parent knowledge of adolescent activities in early adolescence and their prediction of adolescent alcohol use approximately five years later. The current sample consisted of mothers (N = 457) and fathers (N = 368) drawn from a large longitudinal sample (The Adult and Family Development Project: AFDP). The average age was 11.68 in early adolescence and 16.22 in adolescence and 47% of adolescents were female. Parent knowledge was tested as a mediator of the effects of parent alcohol disorder and parent opioid misuse on adolescence alcohol use. This model was examined separately in mothers and fathers. For mothers, alcohol use disorder and prescription opioid misuse both predicted adolescent alcohol use indirectly via parent knowledge. Mothers' alcohol use disorder also directly predicted adolescent alcohol use. For fathers, no direct or indirect effects of alcohol use disorder or prescription opioid misuse were detected although a covariate effect of illicit drug use on parent knowledge emerged. The results are discussed with regards to the processes that may explain how alcohol disorder or prescription opioid misuse affect mothers' knowledge and increase risk for adolescent alcohol use.

Heavier drinking and depression are common mental health concerns in the USA, yet few studies have sought to understand transdiagnostic risk factors for both. Two health-focused risk factors are impulsive personality traits and sleep duration, but research typically separates the two, precluding additive and interactive relations. The current study sought to test a theoretical model where risk conferred from impulsive traits is heightened when individuals have reduced sleep. Public-access data from the National Longitudinal Study on Adolescent to Adult Health (Add Health) were used to test study hypotheses. Participants reported on impulsive traits (i.e., lack of premeditation, sensation seeking), sleep duration, depression, and drinking across three waves spanning adolescence, emerging adulthood, and adulthood. Multilevel models distinguished risk processes at the between- vs. within-person level. At the between-person level, sensation seeking predicted drinking whereas premeditation predicted depression. Additionally, within-person deviations in both traits were associated with drinking, whereas within-person deviations in premeditation were associated with depression. Sleep duration was protective against outcomes at both levels. However, main effects were qualified by interactions at both levels, such that having below average sleep duration heightened the effects of premeditation at the between-person level, whereas within-person decreases in sleep heightened the effects of sensation seeking at the within-person level. Findings support a theoretical model where poor sleep exacerbates risk conferred from impulsive traits. Risk conferred from impulsive traits diverged based upon level of analysis, suggesting that global and just-in-time interventions may benefit from targeting specific impulsive traits as well as sleep.
RESUMO
OBJECTIVE: Decades of research has found support for the motivational model of alcohol use at the between-person level, yet research on event-level drinking motives is in its nascent stage. Similarly, drinking context has been largely ignored in studies of day-level motives. Therefore, the present study sought to test whether drinking context mediates the relation between affect and motivation on drinking outcomes at both day and person levels. METHOD: Emerging adults who drank in solitary and social settings (N = 107; 61.2% female) completed 21 days ecological momentary assessments. Affect was assessed during morning/afternoon reports; drinking motives were assessed during afternoon reports; and past-night drinking context, drinking quantity, and negative consequences were assessed during next morning reports. Two-level multilevel structural equation models tested whether within-person and between-person levels of predrinking affect were indirectly associated with negative consequences through predrinking motives, drinking context (social vs. solitary), and drinking quantity. RESULTS: At the day and person levels, positive affect was associated with higher social and enhancement motives. At the day level, positive affect indirectly predicted consequences through social motives, social (vs. solitary) drinking, and drinking quantity, whereas positive affect indirectly predicted consequences through enhancement motives and drinking quantity above and beyond context. At the day and person levels, negative affect was associated with coping motives, but coping was not associated with context, drinking quantity, nor consequences. CONCLUSIONS: Findings suggest that positive affect was linked to drinking outcomes through motives (enhancement and social) and contexts (social), whereas negative affect was not. Findings suggest that positively valenced drinking motives may be an important just-in-time intervention target. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVE: The theory of aversive transmission posits that children of parents who have an alcohol use disorder (AUD) may abstain or limit their own alcohol use because they believe themselves to be at risk of developing problems with alcohol. The present study examined relationships among parental AUD, perceived parental AUD, perceived risk for AUD, addiction avoidance reasons for limiting alcohol use, and alcohol use using a random intercept cross-lagged panel model. METHOD: Participants (N = 805; 48% female; 28% Latinx) were from a longitudinal study investigating intergenerational transmission of AUD. Parental AUD, perceived parental AUD, perceived risk for AUD, addiction avoidance reasons for limiting alcohol use, and alcohol use (quantity, frequency, and frequency of heavy drinking) were measured every 5 years from late adolescence (Mage = 20) to adulthood (Mage = 32). Random intercept cross-lagged panel models tested whether there were stable between-person relations or time-varying within-person relations among these variables. RESULTS: At the between-person level, perceived parental AUD predicted greater addiction avoidance reasons for limiting alcohol use and greater perceived risk. Those with greater addiction avoidance reasons for limiting alcohol use were less likely to use any alcohol and drank less frequently. Parental AUD was associated with higher levels of alcohol use as well as perceived risk. No consistent cross-lagged paths were found at the within-person level. CONCLUSIONS: Study findings were at the between-person level rather than the within-person level. Future work on aversive transmission is needed to better understand this subgroup of children of parents with AUD. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

BACKGROUND: Impulsive personality traits are strong, consistent risk factors for heavy drinking, and modern theories suggest that impulsive traits may also confer risk for internalizing symptoms. However, it remains unclear which specific impulsive traits are linked with heavy drinking versus internalizing symptoms, and whether heavy drinking and internalizing symptoms are mechanisms of risk for negative alcohol consequences in impulsive individuals. METHOD: Data are from a longitudinal study of young adults (N = 448, Mage = 22.27, 43.5 % female) assessed at baseline (T1), 6 months (T2), and one year later (T3). Longitudinal path models tested whether T1 impulsive traits (i.e., lack of premeditation, lack of perseverance, sensation seeking, positive urgency, negative urgency) were indirectly associated with T3 negative alcohol consequences through heavy T2 drinking and T2 internalizing symptoms (i.e., depression, anxiety, stress). Separate models were tested for positive and negative urgency given strong correlations between these measures. RESULTS: Across models, T1 lack of premeditation indirectly predicted more T3 negative alcohol consequences through heavy T2 drinking. When tested separately, T1 negative urgency indirectly predicted more T3 negative consequences through higher T2 stress and depressive (but not anxiety) symptoms, and T1 positive urgency predicted higher T2 anxiety symptoms, but T2 anxiety was unrelated to T3 negative consequences. Across models, T1 sensation seeking indirectly predicted less T3 negative consequences through decreased T2 depression. CONCLUSIONS: Distinct impulsive traits prospectively predicted heavy drinking and internalizing symptoms, both of which conferred risk for negative alcohol consequences. Findings underscore the importance of targeted interventions based on personality and suggest that decreases in drinking may be more effective prevention for those who lack premeditation, whereas decreases in internalizing, particularly depression/stress, may be critical for those high in negative urgency.

OBJECTIVE: Negative reinforcement models suggest that negative affect should predict event-level substance use, however, supporting daily-life evidence is lacking. One reason may be an emphasis in ecological momentary assessment (EMA) research on use behavior, which is subject to contextual and societal constraints that other substance outcomes, such as craving, may not be subject to. Therefore, the present study tested momentary, within-person reciprocal relations among negative affect and craving for alcohol and cannabis in daily life. METHOD: Adults (N = 48) completed 60 days of EMA, consisting of four daily reports spanning 7 a.m.-11 p.m. assessing current negative affect and alcohol/cannabis craving. Preregistered analyses used dynamic structural equation modeling to test whether (a) within-person increases in negative affect co-occurred with within-person increases in alcohol and cannabis craving, and (b) within-person increases in negative affect predicted later within-person increases in craving (and vice versa), and (c) relations differed by substance use frequency. RESULTS: Within-person increases in negative affect were contemporaneously associated with within-person increases in alcohol and cannabis craving. However, increases in negative affect did not prospectively predict increases in craving, and within-person increases in craving did not prospectively predict within-person increases in negative affect. Within-person relations were not moderated by substance use frequency. CONCLUSIONS: Negative affect and craving were associated in community adults. However, results advance a growing body of EMA work suggesting that the association of daily-life negative affect and substance use is, at best, not straightforward. Careful attention is needed to better translate existing negative reinforcement theory to the realities of daily life. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Emerging adult alcohol and cannabis co-use is on the rise and enacts risk for alcohol misuse/alcohol use disorder (AUD). However, few studies have differentiated whether levels of cannabis use (rather than any cannabis use) moderate between-person risk. Considering low-frequency co-users may use both substances via substitution, low-risk/frequency co-use may not enact the same risk for AUD as higher risk co-use. The present study sought to test this assertion. Public access data on emerging adults from the National Study on Drug Use and Health were used (2002-2019; N = 231,681). Participants reported on their past year alcohol use, cannabis use, as well as AUD symptoms. Regression models tested whether levels of cannabis use frequency moderated the association between alcohol use frequency and AUD symptom counts. A significant interaction of cannabis use frequency by alcohol use frequency predicting AUD symptoms was detected. Individuals who co-used alcohol and cannabis reported more AUD symptoms than those who only used alcohol at the same frequency or less. However, co-use was associated with lower AUD symptom counts than alcohol-only use at higher frequency. Findings suggest that all co-users (and alcohol-only users) are not necessarily created equal, and that relations among co-use and risk for AUD symptoms are complex. Rather than a dichotomy of co-users versus alcohol-only users, between-group risk may depend on frequency of both alcohol and cannabis use.

Models of personality suggest that adolescent substance use may be associated with adolescent impulsive traits as well as changes in impulsive traits from adolescence into emerging adulthood. However, little research has focused on how adolescent alcohol and cannabis co-use, an increasingly popular and risky substance use pattern, may relate to adolescent impulsive traits as well as changes in impulsive traits from adolescence to emerging adulthood. Therefore, the current study tested patterns of adolescent co-use and their links with adolescent impulsive traits and changes in impulsive traits into emerging adulthood. Data come from the Add Health study and encompassed two timepoints spanning adolescence (age 13-18) and emerging adulthood (age 19-25). A combination of latent profile analysis, mean comparisons, and latent difference scores were estimated. Results suggested that four profiles of co-users and alcohol-only users emerged, and profiles differed in levels of adolescent personality and prospective personality change. Importantly, frequent adolescent co-users had higher levels of adolescent sensation seeking and impulsivity, but also reported the steepest decline in both traits into emerging adulthood. Findings are discussed in terms of personality theory and public health implications.
RESUMO
BACKGROUND: The Acquired Preparedness Model (APM) posits that highly impulsive individuals develop stronger positive alcohol expectancies, which in turn predicts heavier drinking. However, most acquired preparedness studies have focused solely on between-person relations, despite the theory suggesting that there are potential developmental-specific within-person relations. Thus, the current study tested the APM from late adolescence into adulthood, while disaggregating within- from between-person relations. METHODS: Data come from a multigenerational study of familial alcohol use disorder (N=653) spanning three waves 5 years apart. Participants reported their lack of conscientiousness, sensation seeking, positive alcohol expectancies, and binge drinking at each wave. First, missing data techniques were used to create a "ghost timepoint," allowing the specification of four developmental-specific timepoints representing late adolescence (age 18 to 20), emerging adulthood (age 21 to 25), young adulthood (age 26 to 29), and adulthood (age 30 to 39). Second, a Random-Intercept Cross-Lagged Panel Model tested between-person and within-person relations among variables. RESULTS: At the between-person level, lower conscientiousness and sensation seeking were correlated with higher positive expectancies, and positive expectancies were correlated with more binge drinking. There were no within-person prospective relations among conscientiousness, sensation seeking, and positive expectancies. However, within-person increases in lack of conscientiousness during late adolescence predicted within-person increases in emerging adult binge drinking, and within-person increases in late adolescent and emerging adult binge drinking predicted within-person increases in lack of conscientiousness during emerging and young adulthood, respectively. Similarly, within-person increases in late adolescent and young adult sensation seeking predicted within-person increases in binge drinking during emerging adulthood and adulthood, respectively. Binge drinking did not reciprocally predict sensation seeking. CONCLUSIONS: Findings suggest that acquired preparedness effects may be between persons rather than within persons. However, several within-person developmental-specific relations among conscientiousness, sensation seeking, and binge drinking were observed, outside of expectancies. Findings are discussed in terms of theory and prevention.
RESUMO
Day-level drinking motives are associated with intensity of drinking and occurrence of negative consequences. However, little is known about how day-level drinking motives relate to alcohol craving, an approach-oriented motivational state proximal to continued drinking. This study tested whether day-level (and between-person) drinking motives were associated with craving during drinking episodes and whether this effect varied by drinking-induced changes in negative/positive affect (PA). Emerging adults (N = 114) took part in up to two waves of 21-day ecological momentary assessments. Participants reported positive/negative affect (NA) prior to and during drinking episodes, drinking motives at beginning of episodes, and craving during all drink reports. Analyses tested whether day-level and between-person (aggregated) drinking motives were associated with heightened craving and whether any effects on craving were moderated by drinking-induced changes in affect. A significant interaction emerged for day-level coping by negative affect, such that higher-than-average coping was associated with less drinking-induced craving when negative affect decreased relative to predrinking levels. However, interactions of between-person coping by negative and positive affect also emerged, such that higher person-level coping was associated with more drinking-induced craving when negative affect and positive affect increased. Day-level and between-person conformity motives by negative affect interactions were also detected, such that higher day-level and between-person conformity motives were associated with more drinking-induced craving when negative affect decreased. Relations between day-level motivation and craving may be sensitive to changes in negative/positive affect while drinking. Future research is needed to differentiate mechanisms through which person-level versus day-level motives relate to craving. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
