RESUMO

OBJECTIVE: The current study provides a proof of concept for an aspect of the trauma and attachment model outlined in Marshall and Frazier (2019), which argues that attachment insecurity is associated with PTSD symptoms via hyperactivating/deactivating coping strategies, especially in the context of high trauma severity. METHOD: 302 participants who had experienced a traumatic event(s) completed a survey. RESULTS: The results showed significant indirect effects between attachment insecurity and PTSD symptoms via hyperactivating/deactivating coping strategies, especially in the context of high trauma severity. In low trauma severity, hyperactivating strategies were not as strongly associated with PTSD symptoms and deactivating strategies not associated with PTSD symptoms. Hyperactivating and deactivating strategies were the mediators for attachment anxiety models and deactivating strategies was the mediator for attachment avoidance models. CONCLUSIONS: This proof of concept for Marshall and Frazier (2019) provides a platform for future research to better understand PTSD symptoms from an attachment framework. Interventions are likely to benefit by assisting people high on attachment avoidance and anxiety to modify their deactivating tendencies following a trauma of high severity and also assisting people high on attachment anxiety to modify their hyperactivating tendencies posttrauma, especially following a high trauma severity.

RESUMO

Limited human studies have directly tested the dissociation between wanting and liking with human substance users, a core tenet of the Incentive Sensitisation Theory (IST). The aim of this study is to test the dissociation between wanting and liking in humans across two commonly used licit substances, alcohol and caffeine. The STRAP-R (Sensitivity To Reinforcement of Addictive and other Primary Rewards) questionnaire was administered to 285 alcohol users (mean age=33.30, SD= 8.83) and 134 coffee users (mean age=33.05, SD=8.10) ranging in their levels of substance use to assess wanting and liking. Findings showed that in high risk alcohol users wanting may drive alcohol consumption more so than liking, compared with low risk alcohol users. However, wanting and liking did not significantly dissociate as alcohol consumption increased. These findings partially support IST. Additionally, IST was not supported in coffee users. It is possible that caffeine functions differently at the neurological level compared with alcohol, perhaps explaining the lack of dissociation emerging in coffee users as caffeine use increased. Nevertheless, the current study makes several contributions to IST research. Future studies should focus on utilising the STRAP-R with a clinically dependent sample to test the dissociation between wanting and liking.

RESUMO

Benzodiazepine-related aggression has received insufficient research attention, in particular little is known about the motivational factors which may contribute to the development of this paradoxical response. The revised Reinforcement Sensitivity Theory provides a theoretical framework from which to understand the relevant underlying motivational processes. The current study aimed to identify the role of approach and avoidance motivational tendencies in the occurrence of benzodiazepine-related aggression. Data regarding benzodiazepine and other substance use, approach and avoidance motivation, and general and physical aggressive behaviour were collected via self-report questionnaires. Participants were a convenience sample (n=204) who reported using benzodiazepines in the previous year. Participants were primarily male (62.7%), aged 18-51 years old. Hierarchical multiple regressions indicated that general and physical aggression were predicted by alprazolam use and Drive, a facet of approach motivation. Overall, lower diazepam use significantly predicted higher levels of general aggression. However, when diazepam-preferring participants were examined in isolation of the larger sample (23.5% of sample), problematic (dependent) diazepam use was associated with greater aggression scores, as was dependence risk for alprazolam-preferring participants (39.7% of sample). The findings highlight the importance of motivational factors and benzodiazepine use patterns in understanding benzodiazepine-related aggression, with implications for violent offender rehabilitation.

RESUMO

An abundance of research has examined craving and affective responses to alcohol; however, minimal emphasis has been placed on the relationship between craving and affective states at specific time points of alcohol consumption. Fifty-nine university students (28 light drinkers, 31 heavy drinkers) completed assessments of craving, and positive and negative affect at baseline (Time 1), immediately following consumption of a standard drink of alcohol (Time 2), and 20 min post consumption (Time 3). In light drinkers, craving was positively correlated with positive affect at all 3 time points. In heavy drinkers, craving was only correlated with positive affect at Time 2. There were no associations between craving and negative affect at any time point in either group. A subsequent profile analysis revealed parallel profiles of craving and positive affect over time in light drinkers, but not heavy drinkers. At 20 min post alcohol consumption, a moderated regression showed that the relationship between craving and positive affect weakened as level of alcohol use increased. These findings suggest that craving is positively associated with positive affect in light drinkers, but as levels of drinking escalate, this association dissipates.

RESUMO

Past research has demonstrated a strong relationship between threat sensitivity and social anxiety; however, the relationship between reward sensitivity and social anxiety is less clear. Further, the role that emotion regulation (ER) may play in the expression of social anxiety disorder (SAD) is rarely considered. The current study tested whether two emotion regulation strategies (emotional suppression and cognitive reappraisal) mediated associations between threat sensitivity and reward sensitivity and social anxiety in a community sample (402 adults, 78% female; Mage=32.49, S.D.age=11.53). Path analyses indicated that low reappraisal mediated the relationship between high threat sensitivity and high social anxiety; and both low reappraisal and high suppression mediated the relationship between low reward sensitivity and high social anxiety. These results highlight the potential role that emotion regulation plays in the relationship between trait motivation and social anxiety.

RESUMO

Although most conceptualizations of social anxiety emphasise that socially anxious individuals are overtly shy, and utilise avoidant behavioural strategies (e.g., risk-aversion, passivity, and submissiveness), there is tentative support for the existence of an approach-motivated subtype, characterised by risk taking and a greater propensity for substance misuse. It is likely that this subtype may help explain the reported co-occurrence of substance misuse and social anxiety. The current study sought to test via latent class analysis whether an approach-motivated social anxiety subtype could be identified within a community sample. A self-report questionnaire was completed by 351 participants (age: 18-74 years). Two distinct social anxiety subgroups were identified: one characterised by prototypical SAD symptomatology (i.e., behavioural inhibition and risk-avoidance), the second by elevated levels of rash impulsiveness, reward sensitivity, risk-taking and co-occurring substance use problems. The current findings provides support for the existence of a distinct approach-motivated social anxiety subtype and indicates that impulsivity may be critical to understanding the comorbid substance use symptomatology of these individuals.

RESUMO

The evidence linking the personality trait of impulsivity and substance misuse is well established. Importantly, impulsivity not only predicts substance misuse problems but has an association with duration in treatment, likelihood of completing treatment and time to relapse. Treatment that focuses on increasing awareness and acceptance of thoughts and emotions may potentially address impulsive behaviour and in this respect improve treatment outcomes for substance misuse. The current paper investigated the relationship between the facet of impulsivity that taps into poor inhibitory control and treatment outcome. In addition, there was a specific focus on ascertaining the impact of an increase in awareness and attentional control measured in 144 adult substance users receiving treatment in a residential therapeutic community. Impulsivity predicted poorer treatment outcome (measured as drug use severity). Increases in awareness and acceptance of emotions and thoughts during treatment were related to better outcome although this was not associated with baseline levels of impulsivity. Clinical and theoretical implications are discussed.

RESUMO

BACKGROUND: Residential drug rehabilitation is often seen as a treatment of last resort for people with severe substance abuse issues. These clients present with more severe symptoms, and frequent psychiatric comorbidities relative to outpatients. Given the complex nature of this client group, a high proportion of clients seeking treatment often do not enter treatment, and of those who do, many exit prematurely. Given the highly social nature of residential drug rehabilitation services, it has been argued that social anxieties might decrease the likelihood of an individual entering treatment, or increase the likelihood of them prematurely exiting treatment. The current paper reports on the protocol of a Randomised Control Trial which examined whether treatment of social anxiety prior to entry to treatment improves entry rates and retention in residential drug rehabilitation. METHOD/DESIGN: A Randomised Control Trial comparing a social skills treatment with a treatment as usual control group was employed. The social skills training program was based on the principles of Cognitive Behaviour Therapy, and was adapted from Ron Rapee's social skills training program. A permutated block randomisation procedure was utilised. Participants are followed up at the completion of the program (or baseline plus six weeks for controls) and at three months following entry into residential rehabilitation (or six months post-baseline for participants who do not enter treatment). DISCUSSION: The current study could potentially have implications for addressing social anxiety within residential drug treatment services in order to improve entry and retention in treatment. The results might suggest that the use of additional screening tools in intake assessments, a focus on coping with social anxieties in support groups for clients waiting to enter treatment, and greater awareness of social anxiety issues is warranted.

RESUMO

BACKGROUND: The repeated pattern of heavy intoxication followed by withdrawal from alcohol (i.e., "binge drinking") has been found to have substantial adverse effects on prefrontal neural systems associated with decision-making and impulse control. Repeated binge drinking has been linked to risky and unplanned sexual behavior; however few studies have examined the role of impulsivity and related cognitive processes in understanding this association. The aim of this study was to examine the relationship between binge drinking, "reflection impulsivity" (deficits in gathering and evaluating information during decision-making), alcohol-related expectancies, and unplanned sexual behavior in a sample of young social drinkers. METHODS: Ninety-two university students completed the alcohol use questionnaire (AUQ) to measure alcohol intake and binge drinking. Two groups (low-binge and high-binge) were generated from the AUQ data. The Information Sampling Task (IST) was used to measure reflection impulsivity; the Alcohol Expectancy Questionnaire (AEQ) for alcohol outcome expectancies; and an unplanned sexual behavior questionnaire, which asked about the number of unplanned sexual events. RESULTS: When compared to the low-binge drinking group, the high-binge drinkers had significantly more unplanned sexual encounters and were impaired on the IST, reflection-impulsivity task. They scored higher on the alcohol expectancy factors of sociability, risk and aggression, negative self-perception, and in particular liquid courage. In a regression analysis, number of unplanned sexual encounters, binge drinking score, and liquid courage were all significantly related. CONCLUSIONS: These results support the role of binge drinking in reduced impulse control and decision-making deficits. The findings indicate that high-binge drinkers demonstrate impairments on an impulse control task similar to that observed in dependent samples and this may be a factor in understanding the negative behavioral consequences associated with excessive alcohol use.

RESUMO

BACKGROUND: Recent work suggests that 2 biologically based traits convey risk for alcohol misuse: reward sensitivity/drive and (rash) impulsiveness. However, the cognitive mechanisms through which these traits convey risk are unclear. This study tested a model predicting that the risk conveyed by reward sensitivity is mediated by a learning bias for the reinforcing outcomes of alcohol consumption (i.e., positive alcohol expectancy). The model also proposed that the risk conveyed by rash impulsiveness (RI) is mediated by drinkers' perceived ability to resist alcohol (i.e., drinking refusal self-efficacy). METHODS: Study 1 tested the model in a sample of young adults (n = 342). Study 2 tested the model in a sample of treatment-seeking substance abusers (n = 121). All participants completed a battery of personality, cognitive, and alcohol use questionnaires and models were tested using structural equation modeling. RESULTS: In both studies, the hypothesized model was found to provide a good fit to the data, and a better fit than alternative models. In both young adults and treatment-seeking individuals, positive alcohol expectancy fully mediated the association between reward sensitivity and hazardous alcohol use. For treatment seekers, drinking refusal self-efficacy fully mediated the association between RI and hazardous drinking. However, there was partial mediation in the young adult sample. Furthermore, neither trait was directly associated with the other cognitive mediator. CONCLUSIONS: The hypothesized model was confirmed on a large sample of young adults and replicated on a sample of treatment-seeking substance abusers. Taken together, these findings shed further light on the mechanisms through which an impulsive temperament may convey risk for alcohol misuse.

RESUMO

High rates of posttraumatic stress disorder (PTSD) have been reported among people seeking treatment for substance use disorders (SUDs), although few studies have examined the relationship between PTSD and substance use in young drug users. This study compared levels of substance use, coping styles, and high-risk triggers for substance use among 66 young adults with SUD, with or without comorbid PTSD. Young people with current SUD-PTSD (n = 36) reported significantly higher levels of substance use in negative situations, as well as emotion-focused coping, compared to the current SUD-only group (n = 30). Severity of PTSD was a significant predictor of negative situational drug use, and emotion-focused coping was found to mediate this relationship. The findings underscore the need for youth substance abuse treatment programs to include coping skills training and management of affect regulation for those individuals with comorbid SUD-PTSD.

RESUMO

The interplay between stable personality characteristics and environmental factors is emphasised in most contemporary approaches to individual differences. This interaction appears to be important in understanding the development of substance use and misuse. Impulsivity related personality traits such as sensation-seeking, novelty seeking, reward-sensitivity and behavioural disinhibition, are strongly linked to adolescent and adult substance use and misuse. The role of anxiety-related traits, in the development of substance misuse is less clear. Nonetheless, anxiety disorders are very common amongst adult substance misusers and almost certainly play a critical role in the maintenance of a substance use disorder and influence treatment effectiveness. The data suggest that personality influences treatment outcomes and yet these individual differences are generally not addressed in treatment. We argue in this review that interventions which are matched to these relevant personality traits may improve treatment outcomes for substance misusers.

RESUMO

This study examined the relationship between personality traits implicated in the drinking literature (i.e., sensation seeking and anxiety) and reactivity to 2 different alcohol cues. The opportunity to consume alcohol was manipulated, and differences in urge and affective reactivity were assessed. Gray's (1987) model of impulsive sensation seeking and anxiety was adopted to investigate relationships between personality and responses to the appetitive (consumption) and aversive (no consumption, nonrewarding) alcohol cues in 40 regular social drinkers. The consumption cue produced increases in appetitive motivation and positive correlations with sensation-seeking traits. The no-consumption cue produced increases in aversive motivation and positive correlations with anxiety-related traits. It was concluded that Gray's model of impulsive sensation seeking and anxiety may provide a useful framework for examining the personality correlates of cue reactivity to different cues.
