Hostility predicts alcohol consumption over a 21-year follow-up in the Gazel cohort

Coping-strategies as a mediator between emotional disorders and problematic alcohol use

BACKGROUND

Epidemiological studies reveal a high prevalence of alcohol use and comorbidity rates with emotional disorders. This study aims to explore the possible mediational effect of stress-coping strategies on the relationship between symptoms of emotional disorders and problematic alcohol use.

METHODS

The sample included 1014 participants (33.82% male, 66.17% female) aged 18 to 75 years (M = 33.0, SD = 15.15). Three mediation analyzes were carried out, for depressive, anxious and somatization symptomatology measured with the LSB-50 in which they acted as an independent variable, the coping strategies of the CSQ as a mediating variable and the problematic alcohol use, measured with AUDIT, as a dependent variable. Additionally, sex, age, educational level, and socioeconomic status were entered as covariates.

RESULTS

In all the models, problematic alcohol use was mediated by Problem-Solving Focus and Open Emotional Expression. However, while in depressive symptoms was a fully mediation, in anxious and somatization symptomatology was partially mediated.

CONCLUSIONS

The similarities found may be due to shared variance between emotional disorders. Interventions focused on Problem-Solving Focus could improve the emotional symptoms and the problematic alcohol use.

Development and evaluation of an online intervention for reducing hostile interpretation bias: A randomized controlled trial

Hostility is a trait-level construct characterized by a generally suspicious and cynical view of other people that results in a tendency to interpret ambiguous social situations in hostile or threatening ways. Cognitive behavioral treatments for hostility have high dropout rates, which may be due to hostile beliefs interfering with treatment engagement. As such, there is a need for an alternative approach to prevent dropout and enhance engagement. The current study therefore developed and tested a 1-session, 40-minute online intervention targeting hostility. It was hypothesized that the hostility intervention would be rated as acceptable as indexed by self-report and completion rates. It was also hypothesized that the hostility intervention would be associated with greater reductions in hostility as compared to a control intervention. Finally, it was hypothesized there would be indirect effects of intervention condition on anger and aggression via changes in hostility. Undergraduates (N = 101) who reported elevated hostility and hazardous alcohol use were randomized to complete either the hostility intervention or a control condition targeting physical health habits. Results showed that individuals randomized to the hostility intervention found the intervention to be highly acceptable and all participants completed the intervention in its entirety. The hostility intervention was associated with significantly faster reductions in hostile interpretations than the control condition with medium to large effects. There were significant indirect effects of intervention condition on month one follow-up anger and aggression via changes in hostile cognitions. This proof-of-concept study provides initial evidence that a brief, single-session intervention may be a promising approach for reducing hostility and its correlates.

Shared and specific associations of substance use disorders on adverse outcomes: A national prospective study

BACKGROUND AND AIMS

Substance use disorders (SUD) frequently co-occur and are associated with numerous adverse outcomes and lower quality of life. The goal of this study was to examine whether the associations of SUD with adverse outcomes occur through a shared liability or are disorder-specific even after taking into account their frequent co-occurrence.

BASIC PROCEDURES

Data were drawn from the National Epidemiological Survey on Alcohol and Related Conditions. The association between nine SUDs assessed at Wave 1 (2001-2002) and a broad range of outcomes (divorce/separation, violence, unemployment, financial crisis, legal problems, problems with a neighbor, friend, or relative, and quality of life) at Wave 2 (2005-2005) were estimated separately and simultaneously using a latent variable model to account for their co-occurrence and identify potential disorder-specific effects.

MAIN FINDINGS

SUD at Wave 1 were associated with increased prevalence of all adverse outcomes at Wave 2 (p < .05). With the exception of nicotine dependence and tranquilizer use disorder, we found no specific associations of any SUD with any adverse outcome. Rather, associations occurred primarily through the latent variable representing the shared effects of the different SUDs.

CONCLUSIONS AND RELEVANCE

Our findings underscore the importance of adopting dimensional approaches to model the co-occurrence of SUD. Because SUD increases the risk of adverse outcomes mainly through a general predisposition representing mechanisms shared across SUD rather than through drug-specific mechanisms, this dimension should be considered as a therapeutic target to substantially advance prevention of adverse outcomes caused by SUD.

Anger, hostility and risk of stroke: a meta-analysis of cohort studies

OBJECTIVE

A growing number of studies have been conducted on the relationship between anger and hostility and the risk of stroke, and their conclusions are not consistent. Accordingly, we performed a meta-analysis to evaluate the relationship between anger and hostility and the risk of stroke.

METHODS

We searched the PubMed and Embase databases for cohort studies, focusing on the relationship between anger and hostility and risk of stroke. Then studies were selected according to the inclusion and exclusion criteria. Study results were pooled using a random effects model.

RESULTS

Ten studies from seven articles involving 52,277 participants were included in this meta-analysis. No significant association was found between anger and hostility level and risk of stroke (hazard ratio 1.08; 95% confidence interval 0.79-1.47). However, a positive association was seen when people with high socioeconomic status were excluded (hazard ratio 1.30; 95% confidence interval 1.06-1.59).

CONCLUSION

A higher level of anger and hostility is not associated with elevated risk of stroke. However, the association is positive among people with lower socioeconomic status.
