Strengthening through adversity: The hormesis model in developmental psychopathology.

BACKGROUND: Employing a developmental psychopathology framework, we tested the utility of the hormesis model in examining the strengthening of children and youth through limited levels of adversity in relation to internalizing and externalizing outcomes within a brain-by-development context. METHODS: Analyzing data from the Adolescent Brain and Cognitive Development study (N = 11,878), we formed latent factors of threat, deprivation, and unpredictability. We examined linear and nonlinear associations between adversity dimensions and youth psychopathology symptoms and how change of resting-state functional connectivity (rsFC) in the default mode network (DMN) from Time 1 to Time 5 moderates these associations. RESULTS: A cubic association was found between threat and youth internalizing problems; low-to-moderate family conflict levels reduced these problems. Deprivation also displayed a cubic relation with youth externalizing problems, with moderate deprivation levels associated with fewer problems. Unpredictability linearly increased both problem types. Change in DMN rsFC significantly moderated the cubic link between threat levels and internalizing problems, with declining DMN rsFC levels from Time 1 to Time 5 facilitating hormesis. Hormetic effects peaked earlier, emphasizing the importance of sensitive periods and developmental timing of outcomes related to earlier experiences. CONCLUSIONS: Strengthening through limited environmental adversity is crucial for developing human resilience. Understanding this process requires considering both linear and nonlinear adversity-psychopathology associations. Testing individual differences by brain and developmental context will inform preventive intervention programming.

RSA instability in mothers of preschoolers and adolescents is related to observations of supportive parenting behaviors.

Respiratory sinus arrhythmia (RSA; a measure of respiratory modulation of vagal control of heart rate) is a dynamic process. For mothers, RSA functioning has been associated with depressive symptoms and coincides with supportive parenting. However, research has largely focused on RSA suppression (i.e., difference score from rest to stress task). The present study examined depressive symptoms and supportive parenting with RSA instability-a dynamic measure of the magnitude of RSA change across a task. In two samples of mothers (N = 210), one with preschoolers (Study 1: n = 108, Mage = 30.68 years, SD = 6.06, 47.0% Black, 43.0% White) and one with adolescents (Study 2: n = 102, Mage = 35.51, SD = 6.51, 75.2% Black), RSA instability was calculated during an interaction task. In both studies, instrumental supportive parenting behaviors were negatively related to RSA instability. Findings provide preliminary support for RSA instability as an indicator of physiological dysregulation for mothers.

COVID-19-related stress exacerbates the effect of child maltreatment on negative affect via increased identity confusion during adolescence.

INTRODUCTION: Exposure to childhood maltreatment may undermine the crucial developmental task of identity formation in adolescence, placing them at risk for developing negative affect. The current study investigated whether COVID-19-related stress intensified the indirect link between child maltreatment and adolescents' negative affect through identity confusion. METHOD: Using multidimensional assessments of child maltreatment (threat vs. deprivation), the study included a sample of 124 adolescents (Mage = 12.89, SD = 0.79; 52% female) assessed before (January 2018 to March 2020) and during the pandemic (May to October 2020) in Georgia, United States. The majority of the participants were European American (78.8%), followed by African American (11.5%), Hispanic (3.8%), Asian/Pacific Islander (1.0%), and other (4.8%). We used structural equation modeling to test (a) the mediating role of identity confusion in the link between childhood maltreatment and negative affect and (b) whether COVID-19-related stress moderated these indirect effects. Simple slopes and Johnson-Neyman plots were generated to probe regions of significant interaction effects. RESULTS: Threat and deprivation predicted an increase in adolescent identity confusion. Additionally, childhood threat and deprivation were indirectly linked to adolescents' negative affect through increased levels of identity confusion. COVID-19-related stress significantly exacerbated the link between identity confusion and negative affect. CONCLUSION: Identity confusion is a mechanism underlying the link between child maltreatment and the development of negative affect in adolescence. Our results inform prevention and intervention programs that aim to reduce negative affect among adolescents who experience threatening and depriving rearing environments.

Childhood adversity and racial discrimination forecast suicidal and death ideation among emerging adult Black men: A longitudinal analysis.

OBJECTIVES: Disproportionate exposure to childhood adversity and the effects of racial discrimination take a toll on Black American men's mental health. Despite increasing rates of suicidal behaviors and thoughts among young adult, Black American men, few longitudinal studies examine their risk for suicidal and death ideation (SDI). We tested a developmental model linking childhood adversity (experiences of deprivation and threatening experiences) and emerging adult exposure to racial discrimination to increases in SDI and examined a potential mechanism for these effects, negative relational schemas. METHOD: A sample of 504 Black men (Mage = 20.7) from rural Georgia were recruited with respondent-driven sampling and completed a baseline survey. Men participated in two additional follow-up surveys (Mage = 21.9 and Mage = 23.5). Hypotheses were tested using structural equation modeling. RESULTS: Analyses largely supported the proposed model. Childhood adversities were associated directly with reports of SDI. Childhood deprivation indirectly predicted SDI via negative schemas (ß = 0.03, 95% CI [.014, .046]). Racial discrimination also indirectly predicted SDI via negative relational schemas (ß = 0.01, 95% CI [.001, .018]). CONCLUSION: Study results suggest that clinical and preventive interventions for suicidality should target the influence of racism and adverse experiences and the negative relational schemas they induce.

The Influence of Pubertal Development on Early Adolescent Sleep and Changes in Family Functioning.

Pubertal development has been separately linked to adolescents' sleep problems and larger family functioning, but research connecting these inter-related processes remains sparse. This study aimed to examine how pubertal status and tempo were related to early adolescents' sleep and their family functioning. Using longitudinal data from the Adolescent Brain and Cognitive Development study, the study's sample (N = 4682) was 49.2% female, was an average of 9.94 years old at baseline, and was 60.1% white. Analyses in the current study modeled the indirect associations between pubertal change and changes in family conflict via adolescent sleep duration and variability of duration. The results suggested that pubertal status and tempo predicted shorter adolescent sleep durations and greater variability in those durations, which predicted residual increases in family conflict. The findings highlight the role of adolescents' pubertal changes in their sleep and how such changes can negatively affect family functioning.

Child maltreatment and youth suicide risk: A developmental conceptual model and implications for suicide prevention.

Experiences of child abuse and neglect are risk factors for youth suicidal thoughts and behaviors. Accordingly, suicide risk may emerge as a developmental process that is heavily influenced by the rearing environment. We argue that a developmental, theoretical framework is needed to guide future research on child maltreatment and youth (i.e., adolescent and emerging adult) suicide, and to subsequently inform suicide prevention efforts. We propose a developmental model that integrates principles of developmental psychopathology and current theories of suicide to explain the association between child maltreatment and youth suicide risk. This model bears significant implications for future research on child maltreatment and youth suicide risk, and for suicide prevention efforts that target youth with child maltreatment experiences.

Biological sensitivity to context as a dyadic construct: An investigation of child-parent RSA synchrony among low-SES youth.

Parenting behaviors are significantly linked to youths' behavioral adjustment, an association that is moderated by youths' and parents' self-regulation. The biological sensitivity to context theory suggests that respiratory sinus arrhythmia (RSA) indexes youths' varying susceptibility to rearing contexts. However, self-regulation in the family context is increasingly viewed as a process of "coregulation" that is biologically embedded and involves dynamic Parent×Child interactions. No research thus far has examined physiological synchrony as a dyadic biological context that may moderate associations between parenting behaviors and preadolescent adjustment. Using a two-wave sample of 101 low-socioeconomic status (SES) families (children and caretakers; mean age 10.28 years), we employed multilevel modeling to examine dyadic coregulation during a conflict task, indicated by RSA synchrony, as a moderator of the linkages between observed parenting behaviors and preadolescents' internalizing and externalizing problems. Results showed that high dyadic RSA synchrony resulted in a multiplicative association between parenting and youth adjustment. High dyadic synchrony intensified the relations between parenting behaviors and youth behavior problems, such that in the context of high dyadic synchrony, positive and negative parenting behaviors were associated with decreased and increased behavioral problems, respectively. Parent-child dyadic RSA synchrony is discussed as a potential biomarker of biological sensitivity in youth.

In or out of sync? Concordance between parent and adolescent sleep varies by family context.

Evidence suggests significant interrelations among parent and adolescent sleep (i.e., concordance). However, less is known regarding how parent-adolescent sleep concordance varies as a function of the family context. This study examined daily and average concordance between parent and adolescent sleep and explored adverse parenting and family functioning (e.g., cohesion, flexibility) as potential moderators. One hundred and twenty-four adolescents (Mage  = 12.90) and their parents (93% mothers) wore actigraphy watches assessing sleep duration, efficiency, and midpoint across 1 week. Multilevel models indicated daily (within-family) concordance between parent and adolescent sleep duration and midpoint. Average (between-family) concordance was found for sleep midpoint only. Family flexibility was linked with greater daily concordance in sleep duration and midpoint, whereas adverse parenting predicted discordance in average sleep duration and efficiency.

The Protective Role of the Autonomic Nervous System in Intergenerational Cycles of Neglect.

Offspring of parents who experienced childhood neglect are at increased risk for developing internalizing problems. Empirical evidence suggests this link is principally mediated through parenting behavior. However, such intergenerational cycles of adversity are found to be disrupted in many families. Parasympathetic nervous system functioning is well documented to mediate individuals' emotion regulation biologically. Respiratory sinus arrhythmia (RSA) is a validated biomarker for parasympathetic activity. The goal of the current study was to investigate the moderating role of parent RSA reactivity in the effect of parents' childhood neglect on their children's internalizing problems, through parental acceptance. Physiological and survey data were collected from 145 dyads (94% mothers; Youth Mage = 12.9, Youth SDage = 0.85). Results suggest that the effect of parents' childhood neglect on their child's internalizing problems was conditional on parents' RSA reactivity. Specifically, higher levels of parents' neglect were only linked to increased risk for youth internalizing problems if parents exhibited a lack of RSA withdrawal. Further, this moderating effect was found to be mediated through parental acceptance. Findings suggest understanding intergenerational consequences of child maltreatment contexts should include consideration of bioregulatory factors.

Unique and Transdiagnostic Dimensions of Reward Functioning in Attention-Deficit/Hyperactivity Disorder and Alcohol Use Disorder Symptoms.

AIMS: Contemporary theories of attention-deficit/hyperactivity disorder (ADHD) and alcohol use disorder (AUD) emphasize core dysfunctions in reward-related processes and behaviors as pathognomonic characteristics. However, to date, it is unclear which domains of reward functioning are unique to ADHD versus AUD symptom dimensions, and which represent underlying shared correlates. METHODS: The current study employed secondary data analyses from a large community sample of emerging adults (N = 602; 57.3% female) and novel transdiagnostic modeling (i.e. bi-factor confirmatory factor analyses and structural equation modeling) of ADHD, AUD and shared symptom dimensions to identify unique and common reward-related dimensions: environmental suppressors, reward probability, hedonic capacity, proportionate substance-related reinforcement and delay discounting. RESULTS: The presence of environmental suppressors was the only reward-related construct that correlated with the underlying ADHD-AUD shared dimension. The AUD symptom dimension was uniquely associated with proportionate substance-related reinforcement, whereas the ADHD symptom dimension was uniquely associated with limited reward probability. No significant associations were found for delay discounting or hedonic capacity. CONCLUSIONS: These novel findings highlight specific aspects of reward-related functioning in ADHD, AUD and shared symptom dimensions. In so doing, this work meaningfully advances theoretical conceptualizations of these two commonly co-occurring presentations and suggests future directions for research on transdiagnostic correlates. Future longitudinal studies should include clinical samples with diagnoses of AUD and ADHD to further identify underlying correlates over time.

Trajectories of Depressive Symptoms Among Black American Adolescents: Sociocultural, Racism and Familial Predictors.

OBJECTIVE: The development of depressive symptoms often increases in adolescence, and for Black American youth, can result in disproportionately long-lasting and deleterious outcomes. Despite the epidemiological trend, scant research has examined the longitudinal development of heterogeneous patterns of depressive symptoms among Black American youth. Moreover, less is known on the impact of contextual covariates on depressive symptom trajectories among Black American youth. The investigation into within-group differences of depressive symptoms is crucial for culturally informed interventions. METHODS: The sample consisted of 472 Black American youth and their primary caregivers from eight counties in Georgia who provided data at five time points (i.e., youth ages 11 to 15). Hypotheses were tested with latent class growth analysis to investigate multiple trajectories of depressive symptoms, and examine sociocultural and familial covariates of trajectory group, including caregiver depressive symptoms, involved vigilant parenting, racial discrimination experiences, Black pride, and internalized racism. RESULTS: Four-classes of depressive symptoms were identified including stable low (58.4%); high start, decreasing (20%); later onset (13%); and high and increasing (8.5%). Family and race-related predictors differentiated youth's depressive symptom trajectories class and identified warning signs for high-symptomology trajectories. CONCLUSIONS: Findings provide novel insights into developmental patterns of depressive symptoms and the role of contextual and sociocultural factors within a sample of Black American youth. Implications include treatment and prevention recommendations.

Posttraumatic Stress Disorder Symptomatology and Substance Use in an Outpatient Concurrent Disorders Sample.

OBJECTIVE: Posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) present a complex and often severe clinical presentation within a concurrent disorders context. The objective of this study was to examine associations between PTSD symptoms and SUD outcomes to better understand the clinical phenomenon of comorbid PTSD and SUD. Multivariate statistical methods were used to test the hypothesis that elevated PTSD symptoms, both at the level of global severity and specific PTSD symptom clusters, are associated with greater substance use and related problems. METHODS: Data were collected from an intake assessment battery within a specialized concurrent disorders outpatient service in Hamilton, ON. The sample comprised 326 participants (mean age = 37.19, 45.4% female). Structural equation models examined associations between PTSD and alcohol, cannabis, and substance use frequency and problems, controlling for age and sex. Alcohol was ultimately dropped from the model due to non-significant bivariate associations. RESULTS: Higher global PTSD symptomatology was significantly associated with higher cannabis and other substance use frequency and related problems. Analyses using PTSD cluster scores showed higher scores for alterations in arousal were positively associated with cannabis-related problems, drug-related problems, and cannabis and other substance use frequency. Avoidance was significantly associated with cannabis frequency and cannabis-related problems. In general, effect sizes were small in magnitude, accounting for between 9% and 25% of variance. CONCLUSION: Significant cluster-level associations indicate the importance of specific PTSD symptoms (hyperarousal, avoidance) in relation to substance use when identifying therapeutic targets among individuals presenting with comorbid PTSD-SUD. This multivariate approach provides a higher resolution and potentially more clinically informative representation of the complex clinical presentation of PTSD and SUD in a concurrent disorder population and could guide the development of more effective treatment paths.

Firm parenting and youth adjustment: Stress reactivity and dyadic synchrony of respiratory sinus arrhythmia.

Parental behaviors are potent risk and protective factors for youth development of externalizing problems. Firm control is a parenting strategy that is inconsistently linked to youth adjustment, possibly due to variations in individual biological contexts. Growing research shows that dyadic coregulation of the autonomic nervous system (e.g., parent-child physiological synchrony) is a neurobiological mechanism that links parenting to youth adjustment. However, physiological synchrony may be context-dependent (e.g., adaptive in positive interactions, maladaptive in negative interactions). We aimed to test the role of dyadic synchrony in respiratory sinus arrhythmia (RSA) during parent-child conflict as a mediator between parent firm control and youth's externalizing problems. To capture youth's stress reactivity, we also tested how galvanic skin response reactivity (GSR-R) moderated this indirect path. The sample included 101 dyads of low socioeconomic-status at-risk preadolescents and parents. Results indicated that youth higher levels of GSR-R significantly intensified the link between parent firm control and dyadic RSA synchrony during conflict. Dyadic RSA synchrony further predicted youth increased in externalizing problems. Overall, results suggest that when parents employ firm control parenting with highly reactive teens, dyadic RSA synchrony elevates, potentially modeling less optimal coping with conflict for the youth, which is associated with increased externalizing problems.

Childhood maltreatment, psychiatric symptoms, and suicidal thoughts among adolescents receiving substance use treatment services.

INTRODUCTION: Childhood maltreatment experiences are associated with future suicidal thoughts and suicide attempts, yet the roles of specific psychiatric symptoms mediating this relation remain to be clarified. To clarify these relations, we tested a model incorporating multiple forms of childhood maltreatment (sexual abuse, physical punishment, emotional neglect), past year psychiatric disorder symptoms during adolescence (anxiety, mood, and conduct disorders) and recent suicidal thoughts. METHODS: We administered structured interviews to 394 adolescents receiving outpatient substance use treatment services in the Southeastern United States (280 males; Mage = 16.33; SDage = 1.15). Structural equation models (SEMs) were used to evaluate the degree to which relations between childhood maltreatment and suicidal thoughts were mediated by specific past-year psychiatric symptoms. RESULTS: Mood disorder symptoms significantly mediated the relation between neglect/negative home environment and suicidal thoughts. This path of influence did not vary by gender. CONCLUSIONS: Childhood maltreatment and subsequent psychopathology influence suicidal thoughts among adolescents receiving substance use treatment services. The findings of the present study have implications for the adaptation and delivery of substance use treatment services to adolescents to enhance treatment engagement and outcomes.

Daytime sleepiness underlies the link between adverse parenting and youth psychopathology among adolescent girls.

INTRODUCTION: Adverse parenting is associated with sleep problems in adolescence, including sleep quality, inadequate sleep, and daytime sleepiness. Adolescents who experience sleep problems are at greater risk for developing internalizing and externalizing problems. However, research on the intervening role of sleep in the link between adverse parenting and youth psychopathology remains limited. The present study aimed to examine the indirect effects of adverse parenting on youth internalizing and externalizing psychopathology via sleep problems, and to examine the moderating role of gender in associations between parenting and sleep. METHODS: Participants were 101 low-income youth aged 9-12 (52.5% female; 75.2% African-American) and their primary caregivers. Families were from a non-metropolitan region in the Southeastern United States. Data were collected at two time points (T1; Mage = 10.28, SD = 1.2; T2; Mage = 12.08, SD = 1.2). Adverse parenting was measured at T1, youth-reported sleep problems (inadequacy, disturbance) and daytime sleepiness were assessed at T2, and parent-reported internalizing and externalizing symptoms were measured at T2. RESULTS: Daytime sleepiness served as an intervening variable in associations between adverse parenting and internalizing and externalizing problems, but sleep problems did not. This indirect association was moderated by gender, such that the association between adverse parenting and daytime sleepiness only emerged as significant for girls. CONCLUSIONS: These findings suggest that daytime-related sleep behaviors may serve as a mechanism through which harsh or neglectful parenting is related to internalizing and externalizing psychopathology in adolescence, particularly for adolescent girls.

Racism and preparation for bias within African American families.

Objectives: Exposure to racism experienced by caregivers poses a threat to child developmental outcomes. The current study examines the effects of caregiver-experienced racism on the development of internalizing behaviors for African American children during a sensitive period in their development of racial awareness. Two aspects of caregiver-provided ethnic racial socialization (ERS), cultural socialization and preparation for bias, were assessed as moderators. Supported by prior research, cultural socialization was hypothesized to be protective. Given that research on preparation for bias in early childhood is sparse or inconclusive, no directional hypothesis was formulated for the moderation effect of preparation for bias. Method: A community-recruited, low-income sample of 130 African American caregivers and their children (T3 Mage = 6.20, T4 Mage = 7.17) reported on past-year experiences with racism, ERS practices, and child internalizing behaviors. Path analyses were utilized to assess the influence of caregivers' racist experiences and ERS practices on children's first grade internalizing behaviors after controlling for kindergarten levels. Results: Cultural socialization was not a significant protective factor as hypothesized. However, caregivers' past-year experiences with racism predicted more anxious and sad behaviors in children when caregivers reported using more preparation for bias. Conclusions: The effects of caregivers' racism experiences on their 6-year-old children's internalizing behaviors were contingent on their use of preparation for bias socialization. This study adds to the literature on racism and further elucidates the role preparation for discrimination plays in developmental outcomes for young African American children.

Physiological Stress Response Reactivity Mediates the Link Between Emotional Abuse and Youth Internalizing Problems.

Youth who are raised in emotionally abusive families are more likely to have poor mental health outcomes such as depression and anxiety. However, the mechanisms of this association are unclear. The present study utilized a longitudinal sample of low-SES youth (N = 101, MageT1 = 10.24) to examine stress response reactivity (i.e. vagal withdrawal, sympathetic activation, and hypothalamic-pituitary-adrenal [HPA] axis activation) as mediators between emotional abuse and prospective youth internalizing symptoms. Results indicated that blunted HPA reactivity to a laboratory social stress task mediated the association between emotional abuse and youth internalizing symptoms. Emotional abuse was also associated with blunted parasympathetic nervous system activity (i.e. less vagal withdrawal than average). In sum, emotional abuse is a potent risk factor for youth internalizing symptoms, and this link may be mediated via dysregulation in physiological stress response systems. Primary prevention of childhood emotional abuse and secondary prevention programs that target self-regulation skills may reduce rates of youth internalizing symptoms and disorders.

Contextual Adversity and Rural Black Men's Masculinity Ideology During Emerging Adulthood.

Evidence documents the importance of individual differences in masculinity ideology for men's biological, social, and psychological wellbeing. Studies investigating the developmental antecedents of masculinity ideology and how it changes during specific developmental phases, however, are scarce. The present study examined the influence of childhood adversity and socioeconomic instability on Black men's masculinity ideology during emerging adulthood. Specifically, we investigated changes in two types of masculinity ideology: (a) respect-based, which is associated with prosocial outcomes such as hard work, education, and fidelity, and (b) reputation-based, which is related to antisocial outcomes such as sexual prowess, toughness, and authority-defying behavior. Hypotheses were tested using structural equation modeling with three waves of data from 504 Black American men aged 19 to 22 at baseline living in resource-poor communities in the rural South. Results indicated that childhood adversity was associated with elevated socioeconomic instability during emerging adulthood. Childhood adversity and socioeconomic instability were associated with decreases in respect-based masculinity and increases in reputation-based masculinity. Indirect effects were detected whereby childhood adversity was associated with respect-based and reputation-based masculinity indirectly via socioeconomic instability. Taken together, these results suggest that childhood adversity and socioeconomic instability forecast changes in the types of masculinity ideology rural Black men endorse during the emerging adulthood transition.

Latent Profile Analysis of Heavy Episodic Drinking in Emerging Adults: A Reinforcer Pathology Approach.

BACKGROUND: Heavy episodic drinking (HED) is a major public health problem among emerging adults (individuals 18 to 25), but with considerable heterogeneity in concurrent substance use and psychopathology. The current study used latent profile analysis (LPA) to detect discrete subgroups of HED based on alcohol, other drug severity, and concurrent psychopathology. A reinforcer pathology approach was used to understand motivational differences among the latent subgroups. METHODS: Participants were 2 samples of emerging adults reporting regular HED, 1 Canadian (n = 730) and 1 American (n = 602). Indicators for the LPA were validated dimensional self-report assessments of alcohol severity, cannabis severity, other drug severity, nicotine dependence, depression, anxiety, posttraumatic stress disorder, and attention-deficit/hyperactivity disorder. Reinforcer pathology indicators were measures of alcohol demand, proportionate substance-related reinforcement, and discounting of future rewards. RESULTS: The LPA yielded parallel 3-class solutions in both samples. The largest subgroup was characterized by comparatively low substance severity and psychopathology (Low overall severity). The second largest subgroup was characterized by comparatively high alcohol and other drug severity (excluding tobacco) and high levels of psychopathology (Heavy alcohol & high psychiatric severity). The third subgroup exhibited high alcohol, smoking and intermediate levels of other substance use and psychopathology (Heavy alcohol, smoking, & intermediate psychiatric severity). The Heavy alcohol & high psychiatric severity and Heavy alcohol, smoking, & intermediate psychiatric severity subgroups exhibited significantly higher alcohol demand, greater proportionate substance-related reinforcement, and steeper delay discounting. CONCLUSIONS: Parallel latent subgroups of emerging adults engaging in HED were present in both samples, and the high-risk subgroups were significantly differentiated by the reinforcer pathology indicators. These latent profiles may ultimately inform heterogeneity in the longitudinal course of HED in emerging adults.

Psychometric Validation of the Brief Alcohol Social Density Assessment in an Adult Community Sample.

BACKGROUND: Individuals' social networks exert a strong influence on alcohol use, but valid assessment of network drinking behavior is typically lengthy and high in participant burden. The aim of this study was to validate the Brief Alcohol Social Density Assessment (BASDA), an efficient measure of perceived alcohol use within a person's social network, in a sample of adult drinkers from the general community. Specifically, the convergent, criterion-related, incremental validity and internal validity were investigated by examining the BASDA in relation to other established measures of drinking motives, weekly drinking level, and severity of involvement. METHODS: Participants were 903 (56% female) adults who reported drinking in the last year and who completed the BASDA, the Drinking Motives Questionnaire, the Daily Drinking Questionnaire, and the Alcohol Use Disorders Identification Test (AUDIT). RESULTS: Significant positive correlations were found between the BASDA and drinking motives, drinking quantity, and the AUDIT (rs = 0.21 to 0.51, ps < 0.001), providing support for convergent validity. There was a significantly higher BASDA score for those scoring at or above an AUDIT cutoff for hazardous drinking (p < 0.001), providing support for criterion-related validity. Finally, beyond motives and covariates, the BASDA was significantly associated with total AUDIT score (ΔR2  = 0.09, p < 0.001), indicating its additive contribution and providing support for incremental validity. Confirmatory factor analysis revealed excellent fit, and all items significantly loaded onto a single factor (p < 0.0001), providing evidence of internal validity. The resulting alcohol social density latent variable was significantly and robustly associated with drinks per week and AUDIT total score. CONCLUSIONS: These findings provide further support for the BASDA as a valid and efficient measure of social network alcohol density for understanding social influences on alcohol misuse.
