Is there a psychopathic element in adolescent drinking? A longitudinal study

While previous studies have examined the relationship between psychopathic traits and alcohol use in adolescents, limited empirical investigations of the longitudinal bidirectional effects of psychopathic traits and alcohol use have been conducted for this age-group. The purpose of the present study was to examine the longitudinal associations among adolescent’s psychopathic traits and their alcohol use, in order to illustrate the directional causal relationship between the two constructs, taking into account demographic effects. Participants were 334 adolescents from Cyprus. The participants responded to self-report questionnaires in two consecutive measurements within a six-month interval. Data were analyzed with cross-lagged structural equation modelling. Results indicated that the Dependence alcohol symptoms in Time 1 were significant predictors of the Interpersonal dimension of psychopathy in T2, and the Behavioural dimension of psychopathy in T1 was a significant predictor of Dependence alcohol symptoms in T2, regardless of previous levels of psychopathy and alcohol use, gender and age effects. Implications for research are discussed.     

Effects of mental workload and caffeine on catecholamines and blood pressure compared to performance variations

Caffeine is characterised as a central nervous system stimulant, also affecting metabolic and cardiovascular functions. A number of studies have demonstrated an effect of caffeine on the excretion of catecholamines and their metabolites. Urinary epinephrine and norepinephrine have been shown to increase after caffeine administration. Similar trends were observed in our study in adrenaline (ADR) and noradrenaline (NORADR) levels and additionally a dose dependent effect of caffeine. The effect of caffeine on cognitive performance, blood pressure, and catecholamines was tested under resting conditions and under mental workload. Each subject performed the test after oral administration of 1 cup and then 3 cups of coffee. Root mean square error (RMSE) for the tracking task was continuously monitored. Blood pressure was also recorded before and after each stage of the experiment. Catecholamines were collected and measured for three different conditions as: at rest, after mental stress alone, after one dose of caffeine under stress, and after triple dose of caffeine under stress. Comparison of the performance of each stage with the resting conditions revealed statistically significant differences between group of smokers/coffee drinkers compared with the other two groups of non-coffee drinkers/non-smokers and non-smokers/coffee drinkers. There was no statistically significant difference between the last two groups. There was an increase of urine adrenaline with 1 cup of coffee and statistically significant increase of urine noradrenaline. Both catecholamines were significantly increased with triple dose of caffeine. Mental workload increased catecholamines. There was a dose dependent effect of caffeine on catecholamines.

The effectiveness of a scientific reasoning intervention for conspiracy theory beliefs

Conspiracy theory (CT) beliefs have become an important policy-relevant research area since the events of the COVID-19 pandemic. Increasing interest has been directed towards strategies that might reduce people's susceptibility to conspiratorial beliefs. In this study, we examined whether encouraging a stronger orientation towards critical scientific appraisal of conspiratorial accounts could reduce CT acceptance. After completing baseline measures of COVID-19 related beliefs and analytical and scientific reasoning abilities, a total of 700 adults were randomly allocated to a control or scientific reasoning manipulation. People assigned to the scientific reasoning condition were found to display significantly lower CT belief endorsement post-intervention as compared to the control group. As well as having implications for the design of future intervention studies, the results of this study encourage a greater focus on specific reasoning skills that may be amenable to a psychoeducation approach, in order to further develop methods to prevent CT beliefs.     

Impact of psychiatric illness upon asthma patients’ health care utilization and illness control. Are all psychiatric comorbidities created equal?

The impact of psychiatric illnesses upon asthma patients' functioning is not well understood. This study examined the impact of psychiatric comorbidity upon illness management in asthma patients using empirically-derived psychiatric comorbidity groups. Participants were a clinic sample of Greek-speaking asthma patients (N = 212) assessed using the Patient Health Questionnaire (PHQ) Somatoform, Depression, Panic Disorder (PD), Other Anxiety Disorder, Eating Disorder (ED) and Alcohol sub-scales. The associations between sub-scales were examined using multiway frequency analysis. The following groups were derived: Somatoform disorder and/or Any Depressive disorder (n = 63), Somatoform disorder and/or Other Anxiety disorder (n = 51), Somatoform disorder and/or Any ED (n = 60), and Any Anxiety group including PD and/or Other Anxiety disorder (n = 24). Across all groups, psychiatric illness was associated with significantly worse asthma control (p < .01). Participants in Any Anxiety group, OR = 4.61, 95% CI [1.90, 11.15], Somatoform and/or Any Depressive disorder, OR = 2.06, 95% CI [1.04, 4.09] and Somatoform and/or Other Anxiety disorder, OR = 2.75, 95% CI [1.35, 5.60] were at higher risk for asthma-related Emergency Room (ER) visits compared to controls. However only Somatoform and/or Any Depressive disorder, OR = 3.67, 95% CI [1.60, 8.72], Somatoform and/or Other Anxiety disorder, OR = 5.50, 95% CI [2.34, 12.74], and Somatoform and/or Any ED, OR = 4.98, 95% CI [2.14, 11.60] group membership were risk factors for asthma-related hospitalizations. Results suggest that while comorbid psychiatric disorders generally negatively impact asthma illness management, different psychiatric comorbidities appear to have disparate effects upon illness management outcomes.     

Studying social cognition in patients with schizophrenia and patients with frontotemporal dementia: theory of mind and the perception of sarcasm

We investigated social cognition and theory of mind in patients with schizophrenia and in patients with frontotemporal dementia in order to elucidate the cognitive mechanisms involved in the breakdown of these skills in psychiatric and neurological patients. Our tasks included videotaped scenarios of social interactions depicting sincere, sarcastic and paradoxical remarks, as well as lies. We found impaired performance of the schizophrenia group on all theory of mind conditions despite their intact understanding of sincere statements. In contrast, the FTD group performed poorly only when they had to rely on paralinguistic cues indicating sarcasm or lies, and not on paradoxical remarks or sarcasm when given additional verbal cues. Our findings suggest that, while current deficits in social and interpersonal functioning in patients with FTD may reflect a decrement in previously acquired skills, similar deficits in patients with schizophrenia may reflect an altogether inadequately learned process.     

Parental attributions and parental involvement

This study examined the existing relation between parental attributions of their child’s achievement, their belief in getting involved in the child’s educational process and their actual behavior regarding this involvement. The participating parents (N = 313) were asked to complete the Parental Attributions Scale and the Parental Involvement Scale. They were also asked to state to what degree they believed that parents in general and they personally as parents should get involved in their children’s educational affairs. Confirmatory factor analysis showed that attributing achievement to internal and controllable factors such as the parent’s own effort influenced positively the strength of the “getting involved” belief. This in turn had a strong effect on actual parental involvement activity.     

Cardiovascular Reactivity During Marital Conflict in Laboratory and Naturalistic Settings: Differential Associations with Relationship and Individual Functioning Across Contexts

Cardiovascular reactivity during spousal conflict is considered to be one of the main pathways for relationship distress to impact physical, mental, and relationship health. However, the magnitude of association between cardiovascular reactivity during laboratory marital conflict and relationship functioning is small and inconsistent given the scope of its importance in theoretical models of intimate relationships. This study tests the possibility that cardiovascular data collected in laboratory settings downwardly bias the magnitude of these associations when compared to measures obtained in naturalistic settings. Ambulatory cardiovascular reactivity data were collected from 20 couples during two relationship conflicts in a research laboratory, two planned relationship conflicts at couples’ homes, and two spontaneous relationship conflicts during couples’ daily lives. Associations between self‐report measures of relationship functioning, individual functioning, and cardiovascular reactivity across settings are tested using multilevel models. Cardiovascular reactivity was significantly larger during planned and spontaneous relationship conflicts in naturalistic settings than during planned relationship conflicts in the laboratory. Similarly, associations with relationship and individual functioning variables were statistically significantly larger for cardiovascular data collected in naturalistic settings than the same data collected in the laboratory. Our findings suggest that cardiovascular reactivity during spousal conflict in naturalistic settings is statistically significantly different from that elicited in laboratory settings both in magnitude and in the pattern of associations with a wide range of inter‐ and intrapersonal variables. These differences in findings across laboratory and naturalistic physiological responses highlight the value of testing physiological phenomena across interaction contexts in romantic relationships.     

Mindfulness,impulsivity, and moral disengagement as parameters of bullying and victimization at school

The aim of the present study was to examine the existing association between mindfulness, impulsivity, moral disengagement, and bullying experiences at school. Longitudinal data were collected in three points in time (T1, T2, T3) with 6 months interval between them. Participants were 558 adolescents attending secondary schools in Cyprus, with their ages ranging from 14 to 17 years (M = 15.3; standard deviation = 0.69). Through structural equation modeling, it was found that mindfulness at T1 had a significant negative effect on both impulsivity and moral disengagement at T2 and these, in turn, had a positive effect on bullying and victimization at T3. Thus, mindfulness had an indirect effect on both bullying and victimization, fully mediated by impulsivity and moral disengagement.
