Hostility and cigarette use: a comparison between smokers and nonsmokers in a matched sample of adolescents

Interpretation bias modification for hostility to facilitate smoking cessation in a sample with elevated trait anger: A randomized trial

Problematic anger is linked with multiple adverse smoking outcomes, including cigarette dependence, heavy smoking, and cessation failure. A smoking cessation intervention that directly targets anger and its maintenance factors may increase rates of smoking cessation. We examined the efficacy of an interpretation bias modification for hostility (IBM-H) to facilitate smoking cessation in smokers with elevated trait anger. Participants were 100 daily smokers (mean age = 38, 62% female, 55% white) with elevated anger were randomly assigned to eight computerized sessions of either IBM-H or a health and relaxation video control condition (HRVC). Participants in both conditions attempted to quit at mid-treatment. Measures of hostility, anger, and smoking were administered at pre-, mid-, post-treatment, as well as at up to three-month follow-up. Compared to HRVC, IBM-H led to greater reductions in hostile interpretation bias, both at posttreatment and follow-up. IBM-H also led to statistically significant reductions in hostility only at posttreatment, and trait anger only at three-month follow-up. Both conditions experienced reductions in smoking, although they did not differ in quit success. We discuss these findings in the context of literature on anger and smoking cessation and provide directions for future research.

Child abuse and aggressiveness in individuals diagnosed with schizophrenia in Lebanon

OBJECTIVES

To identify individual and clinical risk factors of aggressiveness, including exposure to different forms of childhood trauma, in a sample of Lebanese patients with schizophrenia.

METHODS

A total of 131 patients diagnosed with schizophrenia participated in this cross-sectional study.

RESULTS

Higher physical (Beta = 0.24, p < 0.001) and sexual (Beta = 0.29, p = 0.003) abuse, alcohol drinking (Beta = 1.46, p = 0.008), having a history of head trauma (Beta = 1.10, p = 0.041), and male gender (Beta = -1.59, p = 0.009) were significantly associated with higher mean aggression scores.

PRACTICAL IMPLICATIONS

Our investigation of the factors linked to aggressiveness in patients with schizophrenia complement those of earlier findings, showing that the relationship between interacting individual and environmental risk factors and later aggressiveness is quite complex, and needs further longitudinal and prospective studies.

Assessment of Greek Smokers' Psychological Characteristics and Empathy While Smoking in Enclosed Public Spaces and Near Nonsmokers

Background Smoking presents a strong association between emotional intelligence and increased anxiety and depression. Empathy is a form of perception where people feel the emotional states of others as their own. The act of smoking expresses indifference to social norms and the health of nonsmokers, which speaks to smokers' psychology. We conducted this study to identify the impact of smoking in psychology, empathy, and smoking behavior and examine the effect of smokers' psychological characteristics and empathy toward smoking in enclosed public spaces and in front of nonsmokers. Methodology A primary, quantitative, synchronous, correlational, and nonexperimental research was accomplished using validated, reliable questionnaires. We used random sampling to acquire the study population consisting of 453 employees of public dining areas, owners of public dining areas, and medical and nonmedical students at the University of Larissa, Greece. Data were collected via self-completed questionnaires on participant demographic information and smoking habits. We used SPSS Statistics for Windows, version 24.0 (IBM Corp., Armonk, NY) to analyze the data with significance set at 5%. We also used independent samples t-test, Mann-Whitney U test, Spearman's coefficient, chi-square test, and factorial analysis of variance with significance set at 5%. Results We found high levels of empathy in smokers with low psychosomatic symptoms. Smoking significantly affected levels of empathy (p<.001), annoyance when they are in a place where smoking is prohibited, someone else smoking (p<.001), recommendations of someone who smokes in a nonsmoking area to quit (p<.001), and hostility (p<.001). There was a statistically significant effect of double interaction sample category and smoking on empathy (p<.001). Smoking more than 15 cigarettes affected the levels of agreement in the perception that nonsmokers around them are bothered when they smoke (p=.004) and anxiety (p=.002). Perceptions about the annoyance of nonsmokers were negatively correlated with interpersonal sensitivity (p=.003), depression (p<.001), anxiety (p=.003), hostility (p<.001), paranoid ideation (p=.005), psychoticism (p=.001), and Global Severity Index (p=.006). Annoyance, when smoking is prohibited, was positively correlated with empathy (p=.001) while negatively correlated with somatization (p=.012) and hostility (p=.013). Smoking in prohibited places was related to somatization (p=.032), hostility (p<.001), and paranoid ideation (p=.001). Conclusions The purpose of this study was to examine the empathy and psychopathological characteristics of smokers in Greece. Smokers presented high levels of hostility and those who smoke more than 15 cigarettes per day indicated higher levels of anxiety than those who smoke less or not at all. Lower levels of empathy appeared in smokers, regardless of occupation. Smokers presented lower levels of annoyance when they are in a place where smoking is prohibited and someone else smokes. Participants with higher somatization, hostility, and lower empathy are less bothered when they are in a place where smoking is prohibited and someone else smokes. These findings could assist the development of communication materials aimed at smokers to help them understand that others nearby do not enjoy their smoking practices, especially in an enclosed area. These findings could also facilitate feasible antismoking laws with an overall goal to reduce smoking in a population.

Cigarette Smoking and Schizophrenia: Etiology, Clinical, Pharmacological, and Treatment Implications

Recent data suggests that the prevalence of smoking in schizophrenia remains high. While reports suggest that smoking increases the risk of developing schizophrenia, the potential causative role of smoking in this relationship needs further investigation. Smokers with schizophrenia are more likely to have more intense positive symptoms and lower cognitive function, but diminished intensity of extrapyramidal side effects than nonsmoking patients with schizophrenia. They were also more likely to exhibit aggressive behaviour compared to nonsmokers, which could suggest higher levels of baseline aggression. The significant cost associated with regular tobacco expenditure can detract from investment in key domains. Large-scale trials have shown that pharmacotherapy for smoking cessation is effective and does not worsen the risk of developing neuropsychiatric symptoms compared to placebo. Electronic cigarette use among schizophrenia patients is high, and there is emerging evidence supportive of its efficacy. Future improvements include large-scale trials assessing the utility, efficacy, and safety of electronic cigarettes in schizophrenia patients.

Psychometric parameters of the subscale of hostility from the Symptom Checklist 90 (SCL-90)

Abstract The present study aimed to know the psychometric parameters of the SCL-90 hostility scale. For this, two studies were traced; In Study 1, 209 students, mean age 16 years (SD = 1.29), who responded to the Scale of Hostility and a sociodemographic questionnaire. The exploratory factorial analysis indicated a unidimensional structure, whose Cronbach’s alpha was.71. In Study 2, we sought to find additional evidence of validity and reliability counting with 212 students with a mean age of 16 years (SD = 1.19). The confirmatory factorial analysis tested the unifactorial structure and pointed to good adjustment indexes; good internal consistency and composite reliability were also observed. In general, the Scale of Hostility provided evidence of satisfactory validity and reliability.

Differential behavioral and molecular alterations upon protracted abstinence from cocaine versus morphine, nicotine, THC and alcohol

Unified theories of addiction are challenged by differing drug-seeking behaviors and neurobiological adaptations across drug classes, particularly for narcotics and psychostimulants. We previously showed that protracted abstinence to opiates leads to despair behavior and social withdrawal in mice, and we identified a transcriptional signature in the extended amygdala that was also present in animals abstinent from nicotine, Δ9-tetrahydrocannabinol (THC) and alcohol. Here we examined whether protracted abstinence to these four drugs would also share common behavioral features, and eventually differ from abstinence to the prototypic psychostimulant cocaine. We found similar reduced social recognition, increased motor stereotypies and increased anxiety with relevant c-fos response alterations in morphine, nicotine, THC and alcohol abstinent mice. Protracted abstinence to cocaine, however, led to strikingly distinct, mostly opposing adaptations at all levels, including behavioral responses, neuronal activation and gene expression. Together, these data further document the existence of common hallmarks for protracted abstinence to opiates, nicotine, THC and alcohol that develop within motivation/emotion brain circuits. In our model, however, these do not apply to cocaine, supporting the notion of unique mechanisms in psychostimulant abuse.

What could keep young people away from alcohol and cigarettes? Findings from the UK Household Longitudinal Study

Background

Adolescents are vulnerable to risky behaviours that are likely to co-occur. We examined whether happiness, awareness of alcohol- or smoking-related harm or the size of friendship networks would be longitudinally associated with young people’s risky behaviours.

Methods

We used available cases (N=1,729) from adolescents aged between 10 and 15 who participated in waves 2 and 3 of the UK Longitudinal Household Study that has annually collected population representative data from 40,000 UK households. The outcome variable was patterns of cigarette and alcohol use among adolescents (1= persistent non-use; 2= ex-use; 3= initiation; 4= persistent use) that we derived by tabulating current alcohol or cigarette use at waves 2 and 3. Explanatory variables were scores on participants’ perception of overall happiness, awareness of harm due to alcohol and cigarette use, and supportive friendship network size, collected at wave 2. Covariates were participants’ sex, age, base level of self-reported health status, reported religious affiliation, and household social position. All estimates were corrected for the complex survey design and non-response. Multinomial logistic regression was used to test assumed associations by taking persistent cigarette and alcohol use as the reference category.

Results

Findings showed higher happiness scores were longitudinally associated with adolescents’ persistent non-use (RRR=1.06, 95% CI=1.01-1.13). Awareness of alcohol or cigarette use-related harm was longitudinally associated with persistent non-use (RRR=1.24, 95% CI 1.15-1.35) as well as initiation of alcohol or cigarette use (RRR=1.21, 95% CI=1.11-1.32).

Conclusion

Joint interventions to promote happiness and harm awareness could help young adolescents from engaging with drinking alcohol or smoking cigarettes.

Matrix metalloproteinases and psychosocial factors in acute coronary syndrome patients

Psychosocial factors have been linked to cardiovascular diseases independently of traditional risk factors. The impact of psychosocial factors on plaque destabilizing factors, such as matrix metalloproteinases (MMPs) has been proposed although scarcely studied.

OBJECTIVE

To evaluate the relationships between hostility, perceived stress and social support with MMPs activity in patients after an Acute Myocardial Infarction (AMI).

METHODS

Blood samples were obtained from 76 patients on admission, post-angioplasty, 24h, 7 days and 3 months after AMI. Hostility, perceived stress and social support were evaluated by validated questionnaires.

RESULTS

Social support was positively correlated with patientś ejection fraction (r=0.453, p=0.009). Patients with higher infarct size presented increased MMP-2 activity at admission (p=0.04). Patients with one diseased vessel had more social support than those with three diseased vessels (p=0.05). The highest values of MMP-2 and MMP-9 activity were observed at the acute event, decreasing, with the lowest activity at 3 months post-AMI (p<0.001). Only in patients with low social support, hostility correlated with MMP-2 activity, from AMI onset (r=0.645, p=0.013), to 7 days post AMI (r=0.557, p=0.038). Hostility explained up to 28% of the variance in MMP-2 activity (R(2)=0.28, p=0.005). Finally, in patients with high hostility, MMP-9 was positively correlated with IL-1β (r=0.468, p=0.02).

CONCLUSIONS

This study adds weight to the idea that two psychosocial factors, namely hostility and social support, acting jointly, may affect MMP-2 activity. Moreover, in hostile patients, there is a link between IL-1β and MMP-9. These findings support the role of psychosocial factors in plaque destabilization and in the inflammatory process in AMI.
