Acute, Chronic, and Everyday Physical Pain in Borderline Personality Disorder.

PURPOSE OF REVIEW: Physical pain is an underrecognized area of dysregulation among those with borderline personality disorder (BPD). Disturbances are observed within the experience of acute, chronic, and everyday physical pain experiences for people with BPD. We aimed to synthesize research findings on multiple areas of dysregulation in BPD in order to highlight potential mechanisms underlying the association between BPD and physical pain dysregulation. RECENT FINDINGS: Potential biological mechanisms include altered neural responses to painful stimuli within cognitive-affective regions of the brain, as well as potentially low basal levels of endogenous opioids. Emotion dysregulation broadly mediates dysregulation of physical pain. Certain psychological experiences may attenuate acute physical pain, such as dissociation, whereas others, such as negative affect, may exacerbate it. Social challenges between patients with BPD and healthcare providers may hinder appropriate treatment of chronic pain. Dysregulated physical pain is common in BPD and important in shaping health outcomes including elevated BPD symptoms, chronic pain conditions, and risk for problematic substance use.

Modeling momentary reciprocal associations between negative affect and craving for alcohol and cannabis using dynamic structural equation modeling.

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).

Trait impulsivity moderates rate of alcohol consumption in daily life.

INTRODUCTION: Rate of alcohol consumption, the speed with which people drink, has been linked to a range of outcomes, including alcohol use disorder symptoms and increased positive affect. However, minimal work has identified who is most likely to drink at elevated rates. Impulsivity is associated with increased attention to positive reinforcers specifically (e.g., positive affect). We therefore examined whether people higher in trait impulsivity engage in faster consumption during drinking episodes. METHODS: Participants were current drinkers (N = 113; 54 people with borderline personality disorder [BPD], a disorder that involves elevated impulsivity, and 59 community people) who completed a 21-day ecological momentary assessment (EMA) protocol. Multilevel models of drinking episodes (Nobservations = 3,444) examined whether self-reported trait impulsivity, measured at baseline, was associated with faster rise in estimated blood alcohol concentration (eBAC) at each follow-up period. RESULTS: All UPPS sub-scales were associated with faster rise in eBAC across a drinking episode. In a multivariate model including all sub-scales as simultaneous predictors, sensation seeking and (lack of) perseverance were independently positively associated with rate of consumption. Additional analyses indicated that greater negative urgency and sensation seeking were associated with faster rises in eBAC in participants with BPD, relative to community comparisons. CONCLUSION: In a sample that captured a wide spectrum of impulsivity, greater impulsivity was associated with drinking alcohol at a faster rate. People higher in sensation seeking and (lack of) perseverance may be prone to drink at faster rates out of a desire to maximize the hedonic effects of alcohol. PUBLIC SIGNIFICANCE STATEMENT: This study finds that people who are more impulsive tend to drink alcohol faster, putting them at greater risk for negative consequences. This may explain, in part, why impulsivity is linked to experiencing alcohol-related problems.

The Co-occurrence of Personality Disorders and Substance Use Disorders.

PURPOSE OF REVIEW: Despite significant negative outcomes, the co-occurrence of personality disorders (PDs) and substance use disorders (SUDs) continues to be underrecognized, and the mechanisms contributing to this co-occurrence remain unclear. This review summarizes recent work on PD-SUD co-occurrence, with a focus on borderline and antisocial PDs, general substance use patterns among those with PDs, and the association of personality traits with SUDs. RECENT FINDINGS: The prevalence of co-occurring PD-SUD is generally high, with estimates ranging depending on the type of PD and SUD, the population assessed, and the sampling methods and measures used. Current theoretical explanations for co-occurrence include shared etiology and predisposition models, with research highlighting the importance of transactional processes. Potential underlying mechanisms include personality traits and transdiagnostic characteristics. Recent research has increased focus on substances besides alcohol, dimensional models of personality pathology, and transactional explanations of co-occurrence, but more research is needed to disentangle the nuanced PD-SUD relationship.

Family History and Alcohol Use Outcomes: Examining Transmission of Risk through Impulsivity and the Moderating Role of Organized Sports Participation.

BACKGROUND: College students are at risk for alcohol misuse and those who participate in organized sports are at even higher risk. Family history of alcohol problems (FH) and impulsivity are well-documented risk factors for alcohol use outcomes, but no research has examined the role of organized sports participation in moderating these associations. This study examined the associations between FH, alcohol consumption and alcohol use disorder (AUD) symptoms, the role of UPPS-P (Urgency, Premeditation, Perseverance, Sensation Seeking, Positive Urgency impulsive behavior scale) impulsivity dimensions in mediating the association between FH and alcohol use outcomes, and whether these associations vary by students' organized sports participation. METHOD: Participants (N = 3,959, 64.7% female, 51.8% White; Mean age = 18.48 years, SD = .40) were recruited from a large, public university and completed an online survey in the fall and spring semesters of their first year in college. Path analyses were conducted in Mplus. RESULTS: FH was associated with higher levels of alcohol consumption and more AUD symptoms. Lack of premeditation, lack of perseverance, and negative urgency partially mediated the associations between FH and alcohol consumption and AUD symptoms. The association between negative urgency and AUD symptoms was stronger for organized sports participants. CONCLUSIONS: Impulsivity dimensions are risk factors for both alcohol consumption and AUD symptoms and serve as important pathways for the transmission of risk between generations. Prevention and intervention efforts aimed at reducing problematic alcohol use should target impulsivity generally, and particularly negative urgency among college students who participate in organized sports.

A longitudinal examination of relations between competitive athletic participation, drinking norms, impulsivity, and sensation seeking and binge drinking throughout college.

OBJECTIVE: College athletes are a high-risk group for heavy drinking and related risky behaviors and consequences. However, most prior work examining drinking behavior in college athletes has been cross-sectional. Drinking norms predict drinking among athletes, but other potential risk factors, including personality traits have received limited attention. METHOD: Using data from a large sample (n = 2,245) of college students, we examined athletic participation, high-risk personality traits (i.e., impulsivity, sensation seeking), and perceptions of peer drinking behavior (descriptive and injunctive norms) as predictors of binge drinking from prior to college entry through 2 years postcollege. Negative binomial latent growth models were used to examine these predictors of patterns of drinking across the college years. RESULTS: Binge drinking increased through the first 3 years of college before leveling off and decreasing postcollege. Controlling for significant effects of sensation seeking and perceptions of peer attitudes and drinking behaviors, athletic participation at T1 was associated with greater binge drinking at matriculation and greater athletic participation was associated with greater risk across the college years. Normative perceptions and sensation seeking also predicted concurrent drinking in Year 4 of college and impulsivity emerged as an additional predictor. Sensation seeking emerged as a significant predictor of greater postcollege binge drinking. Athletic participation in Year 4 of college indicated no significant risk for greater binge drinking during Year 4 or following graduation. CONCLUSIONS: Early participation in competitive athletics was associated with risk for binge drinking, even when accounting for several social and personality factors. Future studies using momentary assessment may be fruitful for identifying within-subject pathways of risk, including athlete specific factors.
