Gianfranchi E, Tagliabue M, Vidotto G. Personality Traits and Beliefs About Peers' On-Road Behaviors as Predictors of Adolescents' Moped-Riding Profiles. Front Psychol 2018; 9:2483. [PMID: 30581406 PMCID: PMC6293198 DOI: 10.3389/fpsyg.2018.02483] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Accepted: 11/22/2018] [Indexed: 11/13/2022] Open
Abstract
Several efforts aimed at discriminating between different degrees of on-road risky attitudes have been devoted to the identification of personality profiles among young drivers. However, the results are often inconsistent because of the limits of self-report measures. To overcome these limits, we tried to identify different profiles based on our study participants’ driving performances in a virtual environment and to look for psychological predictors of inclusion in one of three profiles. One-hundred and fourteen inexperienced adolescents were involved in this study, which included two experimental sessions. During the first, before riding along five virtual courses on a moped simulator, participants’ sensation seeking, locus of control, aggressiveness and beliefs about their peers’ on-road behaviors were measured by means of self-report tools. During the second session, the participants drove the simulator along six courses that were different from those faced in the first session. A cluster analysis was run on a wide number of indexes extracted from the participants’ performances to detect different riding profiles. Three profiles emerged (Imprudent, Prudent and Insecure), with specific riding patterns. The profiles also differed in terms of riding safety, assessed by means of the scores automatically given by the simulator to the participants’ performances. Reporting an external locus of control, underestimating peers’ on-road risky behaviors and showing less concern for fate among the possible causes of crashes are predictors that increase the risk of being included in the Imprudent profile. Low levels of dangerous thrill seeking predict inclusion in the Prudent profile, whereas high rates of self-reported anger play a role in discriminating the Insecure riders from the other profiles. The study indicates that it is possible to identify riding profiles with different degrees of on-road safety among inexperienced adolescents by means of simulated road environments. Moreover, inclusion in these profiles is predicted by different patterns of personality variables and beliefs. Further research is needed to verify the validity of these conclusions in real road conditions.

Matrix metalloproteinases and psychosocial factors in acute coronary syndrome patients. Psychoneuroendocrinology 2016; 63:102-8.

Abstract
UNLABELLED 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.

Abstract
BACKGROUND Various studies have implicated psychosocial variables (e.g., hostility) in risk of dangerous driving and traffic accidents. However, whether these variables are related to more basic neurobiological factors, and whether such associations have implications for the modification of psychosocial risk factors in the context of driving, have not been examined in depth. This study examined the relationship between hemispheric preference (HP), hostility and self-reported dangerous driving, and the ability to affect driving anger via hemisphere activating cognitive exercises (HACE). METHODS In Study 1, 254 Turkish students completed questionnaires of hostility, HP and driving behavior. In Study 2, we conducted a "proof of concept" experimental study, and tested effects of left, right and neutral HACE on driving anger, by exposing N=650 Turkish students to written scenarios including either logical (left hemisphere), visuo-spatial (right hemisphere) or "mild doses" of both types of contents (control). RESULTS In Study 1, left-HP was associated with higher hostility and with more dangerous driving, and hostility mediated the relationship between L-HP and reported driving behavior. In Study 2, only right-HACE led to immediate significant reductions in self-reported driving anger. CONCLUSIONS Left-HP is related to hostility and to dangerous driving, and it may be possible to partly reduce driving anger by right-HACE. Future studies must replicate these findings with objective measures, more enduring interventions and longer follow-ups.

Abstract
This study was aimed at investigating the relationship between trait forgivingness, general anger, hostility, driving anger, and self-reported aggressive driving committed by the driver him/herself ("self" scale) and perceiving him/herself as an object of other drivers' aggressive acts ("other" scale). The Slovak version of questionnaires was administrated to a sample of 612 Slovak and Czech drivers. First, the factor structure of the Driver Anger Indicators Scale (DAIS) was investigated. Factor analyses of the self and other parts of the DAIS resulted in two factors, which were named as aggressive warnings and hostile aggression and revenge. Next, the results showed that from all dependent variables (scales of the DAIS), self-reported aggressive warnings (self) on the road were predicted best by chosen person-related factors. The path model for aggressive warnings (self) suggested that trait forgivingness and general anger were fully mediated by driving anger whereas hostility proved to be a unique predictor of aggressive behavior in traffic. Driving anger was found to be the best predictor of perceptions that other drivers behave aggressively.

Abstract
OBJECTIVES To date, limited and inconsistent evidence exists regarding racial discrimination and risk of cardiovascular disease (CVD). METHODS Cross-sectional observational study of 1005 US-born non-Hispanic black (n = 504) and white (n = 501) participants age 35-64 randomly selected from community health centers in Boston, MA (2008-2010; 82.4% response rate), using 3 racial discrimination measures: explicit self-report; implicit association test (IAT, a time reaction test for self and group as target vs. perpetrator of discrimination); and structural (Jim Crow status of state of birth, i.e. legal racial discrimination prior 1964). RESULTS Black and white participants both had adverse cardiovascular and socioeconomic profiles, with black participants most highly exposed to racial discrimination. Positive crude associations among black participants occurred for Jim Crow birthplace and hypertension (odds ratio (OR) 1.92, 95% confidence interval (CI) 1.28, 2.89) and for explicit self-report and the Framingham 10 year CVD risk score (beta = 0.04; 95% CI 0.01, 0.07); among white participants, only negative crude associations existed (for IAT for self, for lower systolic blood pressure (SBP; beta = -4.86; 95% CI -9.08, -0.64) and lower Framingham CVD score (beta = -0.36, 95% CI -0.63, -0.08)). All of these associations were attenuated and all but the white IAT-Framingham risk score association were rendered null in analyses that controlled for lifetime socioeconomic position and additional covariates. Controlling for racial discrimination, socioeconomic position, and other covariates did not attenuate the crude black excess risk for SBP and hypertension and left unaffected the null excess risk for the Framingham CVD score. CONCLUSION Despite worse exposures among the black participants, racial discrimination and socioeconomic position were not associated, in multivariable analyses, with risk of CVD. We interpret results in relation to constrained variability of exposures and outcomes and discuss implications for valid research on social determinants of health.

Abstract
BACKGROUND To date, research on racial discrimination and health typically has employed explicit self-report measures, despite their potentially being affected by what people are able and willing to say. We accordingly employed an Implicit Association Test (IAT) for racial discrimination, first developed and used in two recent published studies, and measured associations of the explicit and implicit discrimination measures with each other, socioeconomic and psychosocial variables, and smoking. METHODOLOGY/PRINCIPAL FINDINGS Among the 504 black and 501 white US-born participants, age 35-64, randomly recruited in 2008-2010 from 4 community health centers in Boston, MA, black participants were over 1.5 times more likely (p<0.05) to be worse off economically (e.g., for poverty and low education) and have higher social desirability scores (43.8 vs. 28.2); their explicit discrimination exposure was also 2.5 to 3.7 times higher (p<0.05) depending on the measure used, with over 60% reporting exposure in 3 or more domains and within the last year. Higher IAT scores for target vs. perpetrator of discrimination occurred for the black versus white participants: for "black person vs. white person": 0.26 vs. 0.13; and for "me vs. them": 0.24 vs. 0.19. In both groups, only low non-significant correlations existed between the implicit and explicit discrimination measures; social desirability was significantly associated with the explicit but not implicit measures. Although neither the explicit nor implicit discrimination measures were associated with odds of being a current smoker, the excess risk for black participants (controlling for age and gender) rose in models that also controlled for the racial discrimination and psychosocial variables; additional control for socioeconomic position sharply reduced and rendered the association null. CONCLUSIONS Implicit and explicit measures of racial discrimination are not equivalent and both warrant use in research on racial discrimination and health, along with data on socioeconomic position and social desirability.

Abstract
This study examined the impact of breathing awareness meditation (BAM), life skills (LS) training, and health education (HE) interventions on self-reported hostility and 24-hour ambulatory blood pressure (ABP) in 121 African American (AA) ninth graders at increased risk for development of essential hypertension. They were randomly assigned to BAM, LS, or HE and engaged in intervention sessions during health class for 3 months. Before, after, and 3 months following intervention cessation, self-reported hostility and 24-hour ABP were measured. Results indicated that between pre- and postintervention, BAM participants displayed significant reductions in self-reported hostility and 24-hour systolic ABP. Reductions in hostility were significantly related to reductions in 24-hour systolic ABP. Between postintervention and follow-up, participants receiving LS showed a significant reduction in hostility but not in 24-hour ABP. Significant changes were not found for the HE group in 24-hour ABP or self-reported hostility, but these change scores were significantly correlated. The implications of the findings are discussed with regard to behavioral stress reduction programs for the physical and emotional health of AAs.

Abstract
OBJECTIVES A previously shown relation between psychological factors and the occurrence of flu has not been tested in elderly people, who are at the greatest risk of mortality from flu complications. This study examined whether psychological factors predict the occurrence of influenza-like symptoms (ILS) in elderly residents. DESIGN A prospective correlation design was used. METHOD Our sample included 70 elderly residents of a sheltered home (mean age 83.0 years) who were vaccinated against influenza and assessed for background, biomedical factors (e.g. number of illnesses) and psychological factors (e.g. hostility, depression, life-events, and social support). The occurrence of ILS during 2 subsequent winter months was evaluated by a nurse blind to patients' psychological data, according to explicit valid criteria and physicians' notes. RESULTS Seventeen patients (24.3%) developed ILS. Number of medications, little physical activity, hostility, depression, and little social support significantly predicted ILS. In a multivariate analysis, only number of drugs (relative risk, RR: 1.54; 95% confidence interval, CI: 1.06-2.22) and hostility (RR = 1.18; 95% CI: 1.00-1.38) significantly and independently predicted occurrence of ILS. CONCLUSIONS Psychological factors (particularly hostility) predict occurrence of ILS in an elderly sample. Possible behavioural and immunological mechanisms linking hostility to development of ILS are discussed. These findings add to the literature on psychological factors and flu, and may have implications for the prediction and prevention of flu in elderly people.

Abstract
BACKGROUND Depression and anger/aggression-related traits are thought to promote coronary disease, at least in part, through their associations with stress-related cardiovascular processes. It is unclear whether the effects of these factors on cardiovascular reactivity (CVR) are redundant, additive, or synergistic. PURPOSE The main goal of this study was to examine the independent and interactive effects of depressive symptoms and anger/aggression-related traits in promoting CVR. METHODS Participants were 63 healthy females who completed the Beck Depression Inventory and Buss-Perry Aggression Questionnaire and performed a stressful speaking task. Systolic and diastolic blood pressure (SBP and DBP) and heart rate were recorded. RESULTS Significant interaction effects indicated that depressive symptoms were positively associated with SBP and DBP reactivity among women high in verbal aggression but not among those low in verbal aggression. CONCLUSIONS Depressive symptoms and verbal aggression may interact to promote exaggerated blood pressure responses to stressors, a possible marker for mechanisms that contribute to heart disease.

Abstract
This article describes the reliability and validity of the Spanish-language version of the Chronic Illness Resources Survey (CIRS-Spanish), an instrument used to tailor and evaluate behaviorally focused chronic disease self-management interventions. Forty Spanish-speaking adults with 1 or more chronic conditions completed the CIRSSpanish on 2 occasions, separated by 2 weeks. They also completed a series of 5 other measures to evaluate criterion, convergent validity, and divergent validity. The 22-item CIRS-Spanish demonstrated reasonable levels of reliability and validity similar to the previously validated English-language version and was easily understood by patients. The CIRS-Spanish is a reliable and valid instrument for measurement of multilevel support for chronic illness management in low-income, Spanish-speaking patients with a variety of chronic conditions.

Abstract
OBJECTIVE Sedation is frequently required in critically ill, mechanically ventilated patients. Sedation and analgesia requirements may vary substantially among patients. This study examined whether psychological factors predict amount of sedation requirements beyond the effects of other biomedical parameters. METHODS This study used a prospective correlative design in an eight-bed medical intensive care unit at a tertiary university hospital. Fifty-five adult patients requiring mechanical ventilation were included. We evaluated by questionnaires three psychological factors of patients--hostility, anxiety and desire for control (DC)--as completed by patients' relatives at entry to the intensive care unit. Daily doses of sedatives required were monitored. The primary outcome measurement was midazolam dose expressed in mg/kg/h. RESULTS There was a statistically significant correlation between psychological factors and midazolam dose (mg/kg/h): r values = 0.40 for anxiety, 0.43 for hostility, and 0.46 for DC. Age and pulmonary edema were inversely related to midazolam requirements, whereas smoking, chronic obstructive pulmonary disease, fentanyl dose, and therapeutic intervention scoring system were positively correlated with midazolam doses. In a multiple regression, DC accounted for an additional and significant 5.4% of the variance in midazolam after controlling statistically for the effects of the significant background and biomedical predictors. In the final regression equation, DC and fentanyl were the only significant factors associated with higher sedation requirement. CONCLUSION Premorbid psychological profile independently predicts sedation requirement in critically ill, mechanically ventilated patients. Early identification of such a profile may help in sedation management and patient care. The possible mechanisms and clinical implications are discussed.

Abstract
OBJECTIVE This study examined relationships between tourists' agreeableness and openness to experience (AOE) and rates of coronary heart disease (CHD) mortality in an international context. METHODS AOE was obtained from the "Expedia Tourist Survey" (2002), which asked tourist office staff in 17 places around the world to nominate the two countries with the "best" and two with the "worst" tourists. AOE reflected tourists' behaviour, politeness, interest in other countries' language and foods, and spending money. Rates of CHD mortality were obtained for 22 of the countries, from published epidemiological studies. RESULTS Controlling for alcohol consumption and national health budget, countries with low AOE had higher rates of CHD mortality than countries with high AOE. This was found in both men and women. CONCLUSIONS AOE may be a risk factor of CHD mortality, a concept that is the antonym of hostility. If replicated with standardized AOE measures, these findings may have relevance to preventing CHD mortality.

ACCIDENT; ANALYSIS AND PREVENTION 2004; 36:795-800. [PMID: 15203356 DOI: 10.1016/j.aap.2003.07.004] [Citation(s) in RCA: 31] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2002] [Revised: 05/28/2003] [Accepted: 07/30/2003] [Indexed: 05/24/2023]
Abstract
Prior research has shown that those with alcohol problems have significantly elevated rates of traffic events (i.e. traffic violations and collisions) than licensed drivers from the general population and that treatment is associated with reductions in alcohol-related collisions. However, very little research exists on traffic events and the impact of treatment for cannabis or cocaine clients. The objectives of this research are: (1) to determine whether clients in treatment for a primary problem of alcohol, cannabis or cocaine have significantly elevated rates of traffic events than a matched control group of licensed drivers; and (2) to assess whether a significant reduction in traffic events occurs after treatment for each client group compared to a control group. Driver records of patients admitted to substance abuse treatment in 1994 for a primary problem of alcohol (n = 117), cannabis (n = 80) or cocaine (n = 169) were accessed from the Ministry of Transportation for Ontario, Canada. A comparison group of 504 licensed drivers frequency matched by age, sex and place of residence, was also randomly selected. Data was collapsed into two 6-year time periods: 1988-1993 (i.e. before treatment) and 1995-2000 (i.e. after treatment). Six repeated measures analysis of variance tests were conducted where traffic violations and collisions of three treatment groups (i.e. alcohol, cannabis or cocaine) and a control group were compared before and after treatment. All three treatment groups had significantly more traffic violations than the control group and no significant interactions between time period and group membership were found. For collisions, there was a significant interaction between the alcohol and control groups and between the cocaine and control groups. The average number of collisions for the alcohol and cocaine groups decreased after completing treatment, whereas the number for the control group was stable over the same time periods. Neither the interaction term nor the between group effect was significant in the comparison of the cannabis and control groups. When rates of collisions were calculated based on the period that each driver had a valid license, the interaction term was still significant for the comparison of the alcohol and control groups but not for the cocaine and control groups. The results contribute to existing literature by demonstrating that cocaine and cannabis clients have a higher risk of traffic violations than matched controls and that reductions in collision risk was found after treatment for the alcohol and cocaine groups. More research is needed to better understand the reasons for the higher risk of traffic events and to determine reasons for declines.

Abstract
The purpose of this paper is to review the results and limitations of studies of injury risks associated with cannabis and cocaine use. Three types of fatal and non-fatal injuries are considered: injuries due to collisions, intentional injuries and injuries in general. Four types of studies were reviewed: (I) laboratory studies, (II) descriptive and analytic epidemiological studies on the prevalence of cannabis or cocaine use through drug testing of those injured, (III) studies of non-clinical samples, and (IV) studies of clinical samples of drug users. The research that utilized drug tests showed similar proportions testing positive for cannabis in fatal and non-fatal injury groups, and for collisions, violence and injuries in general. By contrast, large differences in the average proportions testing positive for cocaine were found among these same injury groups. For example, 28.7% of people with intentional injuries (primarily homicides) tested positive for cocaine, while 4.5% of injured drivers tested positive. Studies of non-clinical samples have shown that both cannabis and cocaine use are related to intentional injuries and injuries in general. Results indicate higher risk for all types of injuries among cannabis and cocaine clients in treatment. Strengths and limitations of the different types of studies are discussed. More rigorous studies are needed which should focus on ruling out alternative explanations for relationships between drug use and injuries.

Abstract
Since quality of life (QOL) of hemodialysis (HD) patients is low and frequently difficult to improve by medical therapy, it is important to identify psychosocial correlates and life-domains important for HD patients' QOL. Our hypothesis was that psychosocial factors reflecting appraisal, external and internal resources/impediments correlate with QOL and compensate for adverse effects of disease-related variables on QOL. Forty-eight chronic HD-patients identified and rank-ordered life-domains important for QOL and rated their level of satisfaction with those domains. This was performed using a slightly modified version of the Self-Evaluated Individualized QOL (SEiQOL) Scale. Psychosocial factors included perceived-control (PC), social-support and hostility. Demographic and disease-related factors included age, gender, cardiovascular disease (CVD), diabetes, hematocrit, albumin and C-reactive protein. QOL was significantly correlated with PC (r = 0.65) and social-support (r = 0.38), and inversely correlated with hostility (r = -0.31), diabetes and hypoalbuminemia (all at least p < 0.05). PC mediated effects of certain variables (e.g., albumin, gender, hostility) and moderated effects of little social-support and hypoalbuminemia on QOL. Patients' most important QOL domains were health, with which satisfaction was lowest, followed by family, with which satisfaction was highest. Pending replication with larger samples, assessment and enhancement of PC may improve HD patients' QOL.

Abstract
Recent research demonstrates the importance of inflammatory parameters in the etiology and prognosis of the acute coronary syndrome (ACS). This study explored relations between psychological factors and immunological parameters routinely measured among ACS patients. Forty-two ACS patients completed questionnaires assessing perceived-control, emotional support, hostility, and life-events 2-4 days after hospitalization. Data on total leukocytes and percentages (%) of monocytes, %neutrophils, and %lymphocytes upon admission to hospital were collected from computerized medical charts as well as various biomedical information and risk-factors (e.g., diagnosis, left-ventricle-LV functioning, smoking, and hypertension). Of all significant biomedical variables, LV-function and arrival-time correlated uniquely with total leukocytes. Controlling for LV-function and arrival-time, hostility and life-events positively correlated with %monocytes, and perceived-control and emotional-support inversely correlated with %monocytes. Emotional-support was positively correlated and life-events were negatively correlated with %neutrophils. Macrophages play a pivotal role in plaque instability, the trigger of an ACS. This initiating role, and our finding of a relationship between recruitment of monocytes and a poor psychosocial profile, predictive of ACS, are consistent with a PNI component in the pathophysiology of ACS.

Abstract
This study tested the relationship between psychosocial factors and incidence of Familial Mediterranean Fever (FMF) attacks. Forty-five children with FMF were studied retrospectively. Parents assessed their child's hostility, perceived-control, illness-behavior encouragement (IBE), family dysfunction, and reported number of attacks during the last 12 months. Hostility was positively correlated with number of attacks, especially in children below age 10 and in girls. Family dysfunction was positively correlated with attacks in girls and in children at or above age 10. IBE was inversely correlated with attacks in older children. In children below age 10, number of siblings was positively correlated with attacks, and negatively correlated with attacks in the older group. Psychosocial factors explained 27% of the variability in attacks, after controlling for age and number of siblings, with hostility remaining the only significant predictor of attacks. These findings, if replicated in a prospective study, may guide interventions for preventing FMF attacks.

Abstract
BACKGROUND Psychological factors including hostility, depression and stress have been associated with severity of coronary artery disease (CAD). However, few studies have examined interactions between such factors and typical CAD risk factors. Investigating interactive effects simulates their co-occurrence and complex effects in illness, as well as helping to identify groups of patients at greatest risk of morbidity. This study examined the interactive effects of hostility, hopelessness and daily hassles with family history of CAD in relation to CAD severity. DESIGN Correlation design. METHODS Seventy-three patients were assessed for hostility, hopelessness and daily hassles before undergoing coronary artery angiography. Severity of CAD was assessed by a cardiologist who was blind to patients' psychological data, with a scale considering type and proximity of occluded artery: the Ilia-score. RESULTS Hostility significantly interacted with family history in relation to CAD severity. Hostility was positively correlated with CAD severity when family history was positive (r = 0.43, P< 0.05), but not when family history was absent (r = -0.10, NS). No other interaction effects were found. Interestingly, patients with family history of CAD had significantly lower hostility scores (14.4) compared to patients without such history (19.2; P= 0.002). No background or typical-risk factor correlated with CAD severity. CONCLUSION Hostility synergistically interacted with family history of CAD in relation to CAD severity. The mechanisms of this interaction need to be explored in future studies. Hostility-reduction interventions provided to high-hostile patients with a genetic predisposition to CAD may be relevant for primary and secondary CAD prevention.
