Drinking motives, personality traits and life stressors-identifying pathways to harmful alcohol use in adolescence using a panel network approach

BACKGROUND AND AIMS

Models of alcohol use risk suggest that drinking motives represent the most proximal risk factors on which more distal factors converge. However, little is known about how distinct risk factors influence each other and alcohol use on different temporal scales (within a given moment versus over time). We aimed to estimate the dynamic associations of distal (personality and life stressors) and proximal (drinking motives) risk factors, and their relationship to alcohol use in adolescence and early adulthood using a novel graphical vector autoregressive (GVAR) panel network approach.

DESIGN, SETTING AND CASES

We estimated panel networks on data from the IMAGEN study, a longitudinal European cohort study following adolescents across three waves (aged 16, 19 and 22 years). Our sample consisted of 1829 adolescents (51% females) who reported alcohol use on at least one assessment wave.

MEASUREMENTS

Risk factors included personality traits (NEO-FFI: neuroticism, extraversion, openness, agreeableness and conscientiousness; SURPS: impulsivity and sensation-seeking), stressful life events (LEQ: sum scores of stressful life events), and drinking motives [drinking motives questionnaire (DMQ): social, enhancement, conformity, coping anxiety and coping depression]. We assessed alcohol use [alcohol use disorders identification test (AUDIT): quantity and frequency] and alcohol-related problems (AUDIT: related problems).

FINDINGS

Within a given moment, social [partial correlation (pcor) = 0.17] and enhancement motives (pcor = 0.15) co-occurred most strongly with drinking quantity and frequency, while coping depression motives (pcor = 0.13), openness (pcor = 0.05) and impulsivity (pcor = 0.09) were related to alcohol-related problems. The temporal network showed no predictive associations between distal risk factors and drinking motives. Social motives (beta = 0.21), previous alcohol use (beta = 0.11) and openness (beta = 0.10) predicted alcohol-related problems over time (all P < 0.01).

CONCLUSIONS

Heavy and frequent alcohol use, along with social drinking motives, appear to be key targets for preventing the development of alcohol-related problems throughout late adolescence. We found no evidence for personality traits and life stressors predisposing towards distinct drinking motives over time.

Self-Control Measurement Methodologies: An Integrative Approach

The study of self-control occurs in many different types of experimental settings using a wide range of methodologies. In addition, measures of self-control vary in their procedures and operational definitions from simple questionnaires to complex scenarios where individuals must choose to act or not. The present summary draws on trends within the literature using widely accepted measures of self-control. The measures are organized based on established paradigms in the literature and focus on three categories: executive functioning tasks, delay of gratification tasks, and subjective-report surveys. We also include an "additional measures" category to capture measures that do not readily fit in these three categories. Finally, we discuss recent approaches to the scientific exploration of self-control and integrate the categories of measures used here within these approaches. This integration incorporates a wide range of research paradigms and provides direction for future studies.

Distinct profiles of psychological and neuropsychological functions underlying goal-directed pursuit in schizophrenia

OBJECTIVES

Several components are known to underlie goal-directed pursuit, including executive, motivational and volitional functions. These were explored in schizophrenia spectrum disorders in order to identify subgroups with distinct profiles.

METHODS

Multiple executive, motivational and volitional tests were administered to a sample of outpatients with schizophrenia spectrum diagnoses (n = 59) and controls (n = 63). Research questions included whether distinct profiles exist and whether some functions are impacted disproportionately. These questions were addressed via cluster analysis and profile analysis, respectively.

RESULTS

Some such functions were significantly altered in schizophrenia while others were unaffected. Two distinct profiles emerged, one characterized by energizing deficits, reduced reward sensitivity and few subjective complaints; while another was characterized by markedly increased punishment sensitivity, intact reward sensitivity and substantial subjective reporting of avolitional symptoms and boredom susceptibility.

CONCLUSION

These findings highlight the importance of considering distinct patterns of strengths and deficits in functions governing goal-directed pursuit in schizophrenia that demarcate identifiable subtypes. These distinctions have implications for treatment, assessment and research.

The Association Between Neuroticism and Problematic Social Networking Sites Use: The Role of Fear of Missing out and Self-Control

Problematic use of social networking sites (SNS) has a negative impact on mental health. It has been found that people who score high on neuroticism are especially vulnerable towards engaging with SNS in a problematic way but it is not clear which psychological mechanisms explain this relationship. We addressed this issue by examining the mediating role of fear of missing out and self-control in the relationship between neuroticism and problematic SNS use. For this purpose, we conducted a cross-sectional study (n = 151, 69.5% female, Mage = 26.23, SD = 7.52) and tested for parallel mediation using structural equation modelling. Neuroticism was found to be predictive of increased levels of problematic SNS use. Moreover, neuroticism was associated with both increased levels of fear of missing out and decreased levels of self-control. However, only fear of missing out was found to robustly mediate the relationship between neuroticism and problematic use of SNS. These findings suggest that fear of missing out could be an intervention target to prevent people scoring high on neuroticism from engaging in problematic SNS use.

Exploring the Roles of Dispositional Mindfulness and Cognitive Reappraisal in the Relationship Between Neuroticism and Depression Among Postgraduate Students in China

Objectives: Previous studies revealed a positive association between neuroticism and depression. This study further extended the previous findings by exploring the psychological processes underlying this association among Chinese postgraduates. Guided by theoretical models and empirical research, we proposed a multiple mediation and moderated mediation model to investigate the roles of dispositional mindfulness and cognitive reappraisal in the relationship between neuroticism and depression.

Methods: Using the NEO Five-Factor Inventory, Beck Depression Inventory, Mindfulness Attention Awareness Scale, and Emotion Regulation Questionnaire, 1103 first-year postgraduates at a comprehensive university in China were surveyed. Path analysis was adopted to test the models.

Results: The results showed that dispositional mindfulness mediated the association between neuroticism and depression. Further, this mediating effect was moderated by cognitive reappraisal, with this effect being stronger in individuals with low engagement in cognitive reappraisal.

Conclusion: The results support interrelations among neuroticism, depression, dispositional mindfulness, and cognitive reappraisal as moderated mediation rather than multiple mediation. The results enhance our understanding of psychological mechanisms between neuroticism and depression and provide suggestions for interventions to prevent or reduce depression in highly neurotic postgraduates.

The Impact of Baseline Mindfulness Scores on Mindfulness-Based Intervention Outcomes: Toward Personalized Mental Health Interventions

A growing body of evidence has portrayed mindfulness as a useful tool for dealing with a broad range of psychological problems and disorders. This has created the impression that mindfulness-based interventions (MBIs) can be used to treat nearly all psychological difficulties, in all cases. Nonetheless, little research has been done on how individual differences may contribute to intervention outcomes. The goal of this study was to evaluate the role of baseline mindfulness on participants’ outcomes by examining three prior Randomized Controlled Trials that addressed the impact of MBIs on mental health and mindfulness measures. The participants were 164 people, aged between 12 and 45, from both clinical and non-clinical samples. Our findings indicate that at least two thirds of the change produced by these interventions in terms of mindfulness scores can be predicted by the baseline scores of the same variables. We also found that many trajectories are not only strongly influenced by the initial status of the participants, but also by the intervention performed, as attested to by the significant interactions found. These results stress the need to continue doing research in a way that considers the diversity of participants’ trajectories, increasing the room for intervention improvements aligned with a more personalized health care model.

Mindfulness and Voluntary Work Behavior: Further Support for an Affect Mediation Model

Mindfulness, defined in terms of greater attention and awareness concerning present experience, seems to have a number of psychological benefits, but very little of this research has focused on possible benefits within the workplace. Even so, mindfulness appears to buffer against stress and negative affect, which often predispose employees to deviant behaviors. Conversely, mindful employees may be more engaged with their jobs, which could support organizational citizenship. Two studies (total N = 418) pursued these ideas. In Study 1, part-time employees who were higher in dispositional mindfulness were less prone to job negative affect, which in turn predicted lower levels of workplace deviance. In Study 2, more mindful full-time employees were more engaged, and less stressed, and these variables mediated a portion of the relationship between mindfulness and organizational citizenship. Collectively, the two studies link mindfulness to both traditional forms of voluntary work behavior while highlighting mediational pathways.

How personal characteristics impact phishing susceptibility: The mediating role of mail processing

In the phishing email literature, recent researchers have given much attention to individual differences in phishing susceptibility from the perspective of the Big Five personality traits. Although the effectiveness and advantages of the phishing susceptibility measures in the signal detection theory (SDT) framework have been verified, the cognitive mechanisms that lead to individual differences in these measures remain unknown. The current study proposed and examined a theoretical path model to explore how the Big Five personality traits, related knowledge and experience and the cognitive processing of emails (i.e., mail elaboration) influence users' susceptibility to phishing emails. A sample of 414 Chinese participants completed the 44-item Big Five Personality Inventory (BFI-44), Mail Elaboration Scale (MES), Web Experience Questionnaire, Experience with Electronic Mail Scale, Knowledge and Technical Background Test and a demographic questionnaire. The phishing susceptibility measures were calculated after the participants finished an email legitimacy task in a role-playing scenario. The results showed that the general profile of the "victim personality" included low conscientiousness, low openness and high neuroticism, and Internet experience and computer and web knowledge played an important role. All of these factors have significant indirect effects on phishing susceptibility by influencing mail elaboration. Moreover, the probabilities of checking for further information or deleting the email reflect the sensitivity of email judgment. These findings reveal the mediating role of cognitive processing between individual factors and phishing susceptibility. The theoretical implications of this study for the phishing susceptibility literature and its applications to phishing risk interventions or training programs are discussed.

Personality states mediate the effect of a mindfulness intervention on employees’ work outcomes: A randomized controlled trial

In the last decade, organizational researchers have increasingly recognized the value of studying personality states at work. This line of research has to date mainly focused on outcomes of and situational antecedents of personality state change at work. In this study, we draw on social cognitive theory of self-regulation and the social investment principle to test if a structured intervention can bring about changes in employees’ personality states at work. Specifically, we investigate the effect of a four-week low-dose mindfulness intervention delivered via a mobile application on employees’ personality state change in a multi-group experiment with a passive and an active control group. Employees ( N = 162), either practicing mindfulness, doing brain training exercises, or not receiving any treatment were tracked in a diary study across a period of four weeks. Results of growth curve analyses showed that compared to the control groups, the mindfulness intervention led to significantly more increases in employees’ daily mindfulness, emotional stability and agreeableness across the four-week period. Furthermore, daily agreeableness and emotional stability mediated the effect of the intervention on daily job satisfaction and performance. No intervention effects were found for daily openness, conscientiousness, and extraversion. Implications are discussed for research and practice.

Predictors of Initial Status and Change in Self-Control During the College Transition

Although self-control tends to increase through late adolescence, there are individual differences in patterns of growth. Latent growth modeling was used to investigate change in self-control across students' first year of college (N = 569, M _age = 18.03; 70.3% female; 89.6% White), and whether attachment to parents predicted this change when controlling for personality and demographic variables. Self-control decreased linearly across five assessments, with significant heterogeneity in intercepts and slopes. Personality was associated with initial self-control, and greater avoidant attachment to mothers and openness to experience predicted greater declines. Overall, self-control changes across late adolescence, and attachment and personality explain individual differences in that change, indicating potential intervention targets during emerging adulthood.

Associations of Five Facets of Mindfulness With Self-Regulation in College Students

Mindfulness has been associated with positive mental health functioning across a range of constructs, including self-regulation. Most of this research, however, has investigated mindfulness as a unidimensional domain. Few studies have examined the relationships between specific facets of mindfulness and particular dimensions of self-regulation, including delay of gratification and emotion regulation, despite relevance for mindfulness-based interventions. Two hundred and seventy-eight undergraduate college student participants completed a series of questionnaires examining dispositional mindfulness, difficulties with emotion regulation, and delay of gratification skills. Linear regressions investigated the associations between five facets of mindfulness and each of the two components of self-regulation. Findings revealed that describing, acting with awareness, nonjudging, and nonreacting mindfulness facets were negatively associated with difficulties with emotion regulation, and that observing, acting with awareness, and nonjudging mindfulness facets were positively associated with delay of gratification skills, after accounting for the effects of the other mindfulness subscales. These preliminary findings may have important clinical relevance, as greater self-regulation has critical implications for social, emotional, and academic functioning.

Can mindfulness overcome the effects of workplace ostracism on job performance?

With a basis in the transactional theory of stress and coping, this study investigates the relationship between employees' exposure to workplace ostracism and their job performance, while also considering the mediating role of acquiescence silence and the moderating role of mindfulness. Multisource, three-wave data from employees and their peers in Pakistani organizations reveal that ostracism in the workplace hinders job performance because employees passively withhold relevant ideas about their work due to feelings of acquiescence. The mediating role of acquiescence silence is mitigated if employees can draw from their mindfulness trait. This study accordingly identifies a key mechanism - the passive withholding of pertinent ideas, based on submission - by which workplace ostracism hampers job performance, and it reveals how this process might be contained by encouraging employees' receptive attention and awareness focused on present experiences.

Neuroticism as mental noise: Evidence from a continuous tracking task

OBJECTIVE

Prominent theories of Neuroticism emphasize its potential link to threat- or punishment-sensitivity processes. Even in the absence of external threats, though, Neuroticism may predispose people to a sort of "mental noise," or cognitive instability, that creates problems for ongoing efforts after control. If this is the case, cognitive views of Neuroticism might be needed to complement the primarily emotion-related views that currently exist.

METHOD

In a four study program of research (total N = 541), momentary forms of monitoring and control were assessed using variants of a continuous tracking task.

RESULTS

As hypothesized, the dimension of Neuroticism was consistently linked to performance deficits, regardless of whether aversive sounds were present or not (Studies 1-3), and the relevant deficits also predicted daily levels of negative affect (Study 4).

CONCLUSIONS

The results support the idea that momentary self-regulation is noisier in the context of higher levels of Neuroticism.

The association of self-regulation, habit, and mindfulness with texting while driving

The saturation of mobile phones throughout Australia has led to some individuals being unable to regulate their use within situations that are inappropriate or risky. One of the most prevalent risky mobile phone use behaviours is texting while driving. Attempts to explain texting while driving suggest cognitive variables and personality characteristics are key factors. This study explored relationships between trait self-regulation, habitual text messaging, trait mindfulness, and texting while driving. One hundred and seventy participants comprising Australian undergraduate psychology students and members of the public completed an online survey measuring trait self-regulation, habitual text messaging behaviour, trait mindfulness, and frequency of texting while driving. It was found that habitual texting behaviour mediated the relationship between trait self-regulation and frequency of texting while driving. Additionally, trait mindfulness moderated the relationship between habit and texting while driving, such that habitual texting was significantly, positively related to texting while driving, but only for individuals with low to moderate trait mindfulness. These results suggest personality constructs related to attention, awareness, and control of behaviour play a significant role in counteracting the association that habitual texting behaviour has with the frequency of texting while driving. As these traits are considered malleable, this association may be applicable in future development of intervention programs aimed at increasing control over mobile phone use and reducing the frequency with which people text while driving.

Does Emotional Intelligence Mediate the Relation Between Mindfulness and Anxiety and Depression in Adolescents?

High anxiety and depression are often observed in the Australian adolescent population, and if left untreated, can have long-term negative consequences impacting educational attainment and a range of important life outcomes. The utilization of mindfulness techniques has been associated with decreased anxiety and depression, but the underlying mechanisms for this is only beginning to be understood. Previous research with adult samples has suggested that the development of emotional intelligence (EI) may be one mechanism by which mindfulness confers its benefits on wellbeing. This study is the first to examine the relation between mindfulness, EI, anxiety, and depression in an adolescent population. It was hypothesized that EI would mediate the relationships between mindfulness and anxiety, as well as mindfulness and depression. The sample consisted of 108 adolescents from a public secondary school, aged between 13 and 15 years (M_age = 13.68, SD_age = 0.56, 51 males and 57 females). Participants completed an online self-report questionnaire which measured dispositional mindfulness, EI, anxiety, and depression. The results indicated that one subscale of EI – Emotional Recognition and Expression (ERE) mediated the relation between mindfulness and anxiety, while two subscales of EI – ERE and Emotional Management and Control (EMC) mediated the relation between mindfulness and depression. Future research utilizing a mindfulness intervention should be conducted to examine whether the use of mindfulness increases EI and decreases anxiety and depression in adolescents.

Neuroticism confers vulnerability in response to experimentally induced feelings of thwarted belongingness and perceived burdensomeness: Implications for suicide risk

OBJECTIVE

This study investigated the role of individual differences in neuroticism in conferring increased reactivity to the interpersonal antecedents for suicide proposed by the interpersonal theory of suicide.

METHOD

Undergraduate students (N = 113) were screened and selected to form high (n = 58) and low (n = 55) neuroticism groups, and an experimental computer task was used to manipulate participants' experience of thwarted belongingness and perceived burdensomeness. Participants' self-reported desire to persist in the face of this induced interpersonal adversity was measured.

RESULTS

Results indicate that high neuroticism confers increased reactivity to the experimental induction of the interpersonal antecedents of suicidal ideation: Thwarted belongingness and perceived burdensomeness. Furthermore, this vulnerability corresponds to a diminished desire to persist with the task in the face of interpersonal adversity.

CONCLUSIONS

Neuroticism confers vulnerability for suicidal desire via an increased reactivity to the proximal, causal risk factors proposed by the interpersonal theory of suicide. This has implications for considering how personality risk factors such as neuroticism may interact with proximal interpersonal risk factors to increase suicidal ideation.

The mindful personality: A meta-analysis from a cybernetic perspective

Dispositional mindfulness (DM), or the tendency to attend to present moment experience, may have important implications for the structure of human personality. However, relationships between DM and the Big Five Model of Personality (BF) have not been definitively established. Therefore, the purpose of this meta-analysis was to extend previous investigations of the relationship between DM and the BF, utilizing a larger sample of studies, attending to relational inconsistencies potentially associated with alternative methods of operationalizing DM, conducting the first meta-analysis of the DM subdomains in relation to the BF, and situating the results in a cybernetic model. Results indicate that neuroticism evidenced the strongest, negative relationship with DM and conscientiousness evidenced the strongest, positive relationship with DM, suggesting the mindful personality may be characterized principally by emotional stability and conscientious self-regulation - potentially reflective of an inclination towards the personality metatrait stability. Measurement differences were also observed, with the mindful personality arrived at through the FFMQ differing to some extent from the mindful personality emerging from the MAAS. Broadly, the mindful personality associated with the FFMQ appears to reflect greater personality complexity, with the FFMQ evidencing associations with all five personality factors while the MAAS appears primarily linked with only three personality factors (Neuroticism, Conscientiousness and Agreeableness). Examination of the relationships between the BF and DM at the facet level also suggest unique patterns of association between the DM facets and each of the personality factors.

Understanding the relationship between suicidality, current depressed mood, personality, and cognitive factors

OBJECTIVES

Links between suicidality and depressed mood are well established. There is, however, little information about the emotional regulation processes that underlie the relationship between suicidality and current low mood, and how these processes differ between groups of never-suicidal (NS), suicidal ideators, and suicide attempters. As suicidality and depression are heterogeneous constructs, this study aimed to conduct within- and between-group comparisons of known suicide risk factors that are associated with emotion regulation (neuroticism, trait aggression, brooding, impulsivity, and overgeneral autobiographical memories).

DESIGN

Correlational design using between- and within-group comparisons from self-report measures.

METHODS

Inter- and intragroup differences were identified using Pearson's correlation coefficients and tests of difference. An analysis of indirect effects was used to investigate whether the relationship between suicidality and current low mood was mediated by neuroticism, trait aggression, brooding, impulsivity, and overgeneral autobiographical memories, and if this relationship varied according to group type.

RESULTS

Brooding appeared to be a consistent feature of all three groups and was closely related to current low mood. Compared to the NS group, the relationship between suicide attempts and current low mood showed greater associations with brooding, trait aggression, and overgeneral autobiographical memories. Compared to the NS group, the suicidal ideation group showed stronger associations with neuroticism and impulsivity, but these factors did not correlate with low mood.

CONCLUSION

These results suggest a need for larger studies to focus on heterogeneity within suicidal populations and consider how different combinations of risk factors may heighten or reduce suicide risk.

PRACTITIONER POINTS

It is well known that the severity and intensity of suicide and depressed presentations vary because of underlying dispositional and contextual factors (Fried & Nesse, ) which, in turn, affect how events are interpreted and responded to. Despite this, there is little research about how these mechanisms operate in different types of suicide groups, and their influence on the relationship between suicidality and current low mood. Understanding interrelationships that affect current low mood is of clinical significance because past suicidal history and deteriorations in already negative mood are linked to repeated suicide attempts and completion. Our findings show that ruminative brooding, defined as a tendency to repeatedly think about emotional aspects of an event, consistently correlates with current low mood across different types of suicidal groups (NS, suicidal ideators, and suicide attempters), and across analyses. Findings also show that suicidal ideation and attempt groups were associated with specific personality characteristics that increased the propensity of emotional responding and interpretation compared to the NS group. The relationship between suicide attempt and current low mood had a higher propensity to be influenced by trait aggression, brooding, and overgenerality compared to the NS group. In contrast, although the suicidal ideation group correlated more strongly with neuroticism and impulsivity, these factors did not influence current low mood. In terms of clinical practice, these findings imply that specific styles of interpretation and thinking may maintain the relationship between suicidality and current low mood. Given the cross-sectional nature of the study, however, it is not possible to imply causality. Nevertheless, the findings obtained provide some support for transdiagnostic models of cognitive-behavioural processes that could be developed further.

The joint effect of personality traits and perceived stress on pedestrian behavior in a Chinese sample

While improper pedestrian behavior has become an important factor related to road traffic fatalities, especially in developing countries, the effects of personality traits and/or stress on pedestrian behavior have been rarely reported. The current study explored the joint effects of five personality traits (i.e., extraversion, openness, neuroticism, normlessness and altruism) and global perceived stress (measured with the Perceived Stress Scale-10) on pedestrian behavior (measured with the Pedestrian Behavior Scale) in 311 Chinese individuals. Results showed that altruism, neuroticism and openness significantly affected different pedestrian behavior dimensions, while global perceived stress also significantly and positively predicted positive behavior. Moreover, the effect of neuroticism on positive behavior was fully mediated by stress. Some explanations and implications are provided in the discussion section.

Dispositional Mindfulness and Psychological Health: a Systematic Review

Interest in the influence of dispositional mindfulness (DM) on psychological health has been gathering pace over recent years. Despite this, a systematic review of this topic has not been conducted. A systematic review can benefit the field by identifying the terminology and measures used by researchers and by highlighting methodological weaknesses and empirical gaps. We systematically reviewed non-interventional, quantitative papers on DM and psychological health in non-clinical samples published in English up to June 2016, following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A literature search was conducted using PsycINFO, PubMED, Medline and Embase, and 93 papers met the inclusion criteria. Within these, three main themes emerged, depicting the relationship between DM and psychological health: (1) DM appears to be inversely related to psychopathological symptoms such as depressive symptoms, (2) DM is positively linked to adaptive cognitive processes such as less rumination and pain catastrophizing and (3) DM appears to be associated with better emotional processing and regulation. These themes informed the creation of a taxonomy. We conclude that research has consistently shown a positive relationship between DM and psychological health. Suggestions for future research and conceptual and methodological limitations within the field are discussed.

The Role of Impulsivity in the Relation Between Negative Affect and Risky Sexual Behaviors

While risky sexual behavior associates with negative affect, and impulsivity often increases during negative affective states, little is known about the interrelations of these factors. This study examined whether impulsivity explained the relation between negative affect and risky sex among college students. Negative affect exhibited an indirect effect via impulsivity on number of sexual partners for both males and females, and on inconsistent condom use for females, but not males. Results suggest risky sex may serve to regulate negative affect, proposing the importance of negative affect in future strategies to reduce risky sex among young adults.

Differences of Socio-psychology, Eating Behavior, Diet Quality and Quality of Life in South Korean Women according to Their Weight Status

We aimed at assessing psychological variables and eating behaviors on quality of diet and life in South Korean women according to their weight status. Socio-psychology, eating behavior, quality of diet and quality of life data were assessed in 114 women (mean age: 34.5 ± 8.09 years). NEO Personality Inventory (NEO-PI-RS) and coping styles questionnaire were used to assess socio-psychology variables, and eating behavior was assessed using the Eating Attitudes Test-26 (EAT-26), Dutch Eating Behavior Questionnaire (DEBQ), and General Food Craving Questionnaire Test (G-FCQ-T). Quality of diet was analyzed by Diet Quality Index-international (DQI-I), and obesity-related quality of life was evaluated using the Korean Obesity-related Quality of life Scale (KOQOL). Significant differences were in the psychological variables and eating behaviors in the obese group than the normal and overweight groups (p < 0.05). The overall score of DQI-I was significantly lower in the obese group than that of their counterparts (p < 0.05). BMI was positively correlated with neuroticism, emotional eating, and obesity-related quality of life, and negatively correlated with diet quality. Neuroticism was positively correlated with emotional eating and food craving. Emotional eating was positively correlated with obesity-related quality of life. In conclusion, women with a higher BMI had significantly more problematic eating behaviors, poor diet quality and quality of life.

Physical Aggression and Mindfulness among College Students: Evidence from China and the United States

Background: The link between trait mindfulness and several dimensions of aggression (verbal, anger and hostility) has been documented, while the link between physical aggression and trait mindfulness remains less clear. Method: We used two datasets: one United States sample from 300 freshmen males from Clemson University, South Carolina and a Chinese sample of 1516 freshmen students from Shanghai University of Finance and Economics. Multiple regressions were conducted to examine the association between mindfulness (measured by Mindful Attention and Awareness Scale (MAAS)) and each of the four subscales of aggression. Results: Among the Clemson sample (N = 286), the mindfulness scale had a significant negative association with each of the four subscales of aggression: Hostility: β = −0.62, p < 0.001; Verbal: β = −0.37, p < 0.001; Physical: β = −0.29, p < 0.001; Anger: β = −0.44, p < 0.001. Among the Shanghai male subsample, the mindfulness scale had a significant negative association with each of the four subscales of aggression: Hostility: β = −0.57, p < 0.001; Verbal: β = −0.37, p < 0.001; Physical: β = −0.35, p < 0.001; Anger: β = −0.58, p < 0.001. Among the Shanghai female subsample (N = 512), the mindfulness scale had a significant negative association with each of the four subscales of aggression: Hostility: β = −0.62, p < 0.001; Verbal: β = −0.41, p < 0.001; Physical: β = −0.52, p < 0.001; and Anger: β = −0.64, p < 0.001. Discussion: Our study documents the negative association between mindfulness and physical aggression in two non-clinical samples. Future studies could explore whether mindfulness training lowers physical aggression among younger adults.

Dispositional mindfulness is predicted by structural development of the insula during late adolescence

•

Adolescence is a critical period for the development of self-regulatory abilities.

•

The cultivation of mindfulness has been associated with improved self-regulation.

•

We examined brain development and dispositional mindfulness in adolescence.

•

Adolescents with higher levels of mindfulness demonstrated less thinning in the left anterior insula.

Adolescence is a critical period of development, in which the increasing social and cognitive demands of independence need to be met by enhanced self-regulatory abilities. The cultivation of mindfulness has been associated with improved self-regulation in adult populations, and it is theorized that one neurodevelopmental mechanism that supports this capacity is the development of the prefrontal cortex. The current study examined the neurodevelopmental mechanisms associated with dispositional mindfulness in adolescence. Using a longitudinal within-persons design, 82 participants underwent structural magnetic resonance imaging (MRI) assessments at approximately ages 16 and 19, and also completed self-reported measurements of mindfulness at age 19. It was hypothesized that adolescents who demonstrated greater thinning of frontal cortical regions between the age of 16 and 19 would exhibit higher dispositional mindfulness levels at age 19. Results indicated that, contrary to predictions, adolescents with higher levels of mindfulness demonstrated less thinning in the left anterior insula. By contrast, higher IQ was associated with greater thinning of the right caudal middle frontal and right superior frontal regions. The involvement of insula development in mindfulness is consistent with a direct role for this structure in managing self-regulation, and in doing so concords with recent models of self-referential interoceptive awareness.

Does Personality Moderate the Effects of Mindfulness Training for Medical and Psychology Students?

The majority of mindfulness research to date has reported only on the group-level effects of interventions. Therefore, there is a need to better understand who is most likely to benefit from mindfulness interventions. This study reports on moderation analyses from a two-centre randomised controlled trial of mindfulness-based stress reduction (MBSR) among 288 medical and psychology students. The study investigated whether baseline personality factors (neuroticism, conscientiousness and extroversion) and baseline mindfulness moderated effects on mental distress, study stress and subjective well-being measured after the intervention. An increased effect of the intervention on mental distress and subjective well-being was found in students with higher scores on neuroticism. Students with higher scores on conscientiousness showed an increased effect of mindfulness training on study stress. The training protected students against an increase in mental distress and study stress and a decrease in subjective well-being that was seen in the control group. Baseline mindfulness and extroversion did not moderate the effects of the intervention on the outcomes. The majority of the 288 medical and psychology students in the study sample were female. Female participants scored significantly higher on neuroticism and conscientiousness, and they may therefore be an important target group for mindfulness interventions among students.

Neuroticism associated with cocaine-induced psychosis in cocaine-dependent patients: a cross-sectional observational study

Background

Cocaine consumption can induce transient psychotic symptoms, which has been correlated with more severe addiction and aggressive behavior. However, little is known about the nature of the relationship between personality traits and psychotic symptoms in cocaine-dependent patients. This study examined the relationship between neuroticism and cocaine-induced psychosis.

Methods

A total of 231 cocaine-dependent patients seeking treatment were recruited to the study. Personality was evaluated by the Zuckerman-Kuhlman Personality Questionnaire. Cocaine-induced psychosis questionnaire, SCID-I, and SCID-II were used to evaluate comorbidity and clinical characteristics. Data analysis was performed in three steps: descriptive, bivariate, and multivariate analyses.

Results

Cocaine-induced psychosis was reported in 65.4% of the patients and some personality disorder in 46.8%. Two personality dimensions (Neuroticism-Anxiety and Aggression-Hostility) presented a significant effect on the risk of experiencing psychotic symptoms (t(229) = 2.69, p = 0.008; t(229) = 2.06, p = 0.004), and patients with psychotic symptoms showed higher scores in both variables. On the multivariate analysis, only Neuroticism remained as a significant personality factor independently associated with psychotic symptoms (Wald = 7.44, p<0.05, OR = 1.08, CI 95% 1.02–1.16) after controlling for age, gender and number of consumption substances.

Conclusions

An association between high neuroticism scores and presence of psychotic symptoms induced by cocaine has been found, independently of other consumption variables. Personality dimensions should be evaluated in cocaine-dependent patients in order to detect high scores of neuroticism and warn patients about the risk of developing cocaine-induced psychotic symptoms.

Relationship between Self-Focused Attention and Mindfulness in People with and without Hallucination Proneness

The purpose of this work was to study the relationship between self-focused attention and mindfulness in participants prone to hallucinations and others who were not. A sample of 318 healthy participants, students at the universities of Sevilla and Almería, was given the Launay-Slade Hallucinations Scale-revised (LSHS-R, Bentall & Slade, 1985). Based on this sample, two groups were formed: participants with high (n = 55) and low proneness (n = 28) to hallucinations. Participants with a score higher than a standard deviation from the mean in the LSHS-R were included in the high proneness group, participants with a score lower than a standard deviation from the mean in the LSHR-R were included in the second one. All participants were also given the Self-Absorption Scale (SAS, McKenzie & Hoyle, 2008) and the Southampton Mindfulness Questionnaire (SMQ, Chadwick et al., 2008). The results showed that participants with high hallucination proneness had significantly higher levels of public (t(80) = 6.81, p < .001) and private (t(77) = 7.39, p < .001) self-focused attention and lower levels of mindfulness (t(81) = -4.56, p < .001) than participants in the group with low hallucination proneness. A correlational analysis showed a negative association between self-focused attention (private and public) and mindfulness (r = -0.23, p < .001; r = -0.38, p < .001 respectively). Finally, mindfulness was found to partly mediate between self-focused attention and hallucination proneness. The importance of self-focused attention and mindfulness in understanding the etiology of hallucinations discussed and suggest some approaches to their treatment.

Trait self-control predicts adolescents' exposure and reactivity to daily stressful events

The current study used an influence model of personality and stress processes to examine the association between individual differences in trait self-control and daily stress exposure and reactivity in adolescent youth. A total of 129 adolescents (Mage  = 14.7 years, 59% female) completed individual difference measures of self-control, neuroticism, and measures of responses to stress. Participants then reported on daily stressful events, stress severity, mood, coping, and mindlessness (a predictor of acting on impulse) for 14 consecutive days. Self-control predicted less exposure to daily stress, less reactivity to daily stress, and more adaptive responses to stress. Specifically, adolescents with higher self-control experienced fewer daily stressors and reported lower stress severity, particularly when daily mindlessness was high. Second, adolescents with higher self-control reported less mindlessness in response to daily stress relative to those with lower self-control, but they did not show differences in emotional reactivity to stress. Finally, results also offered evidence for an indirect effect of problem-focused coping strategies between self-control and emotional reactivity to stress. The current investigation illustrates the importance of trait self-control in daily stress processes among adolescents and suggests possible mechanisms through which self-control confers these positive effects.

Psychometric assessment of the Mindful Attention Awareness Scale (MAAS) among Chinese adolescents

The Mindful Attention Awareness Scale (MAAS) has the longest empirical track record as a valid measure of trait mindfulness. Most of what is understood about trait mindfulness comes from administering the MAAS to relatively homogenous samples of Caucasian adults. This study rigorously evaluates the psychometric properties of the MAAS among Chinese adolescents attending high school in Chengdu, China. Classrooms from 24 schools were randomly selected to participate in the study. Three waves of longitudinal data (N = 5,287 students) were analyzed. MAAS construct, nomological, and incremental validity were evaluated as well as its measurement invariance across gender using latent factor analyses. Participants' mean age was 16.2 years (SD = 0.7), and 51% were male. The 15-item MAAS had adequate fit to the one-dimensional factor structure at Wave 1, and this factor structure was replicated at Wave 2. A 6-item short scale of the MAAS fit well to the data at Wave 3. The MAAS maintained reliability (Cronbach's α = .89-.93; test-restest r = .35-.52), convergent/discriminant validity, and explained additional variance in mental health measures beyond other psychosocial constructs. Both the 15- and 6-item MAAS scales displayed at least partial factorial invariance across gender. The findings suggest that the MAAS is a sound measure of trait mindfulness among Chinese adolescents. To reduce respondent burden, the MAAS 6-item short-scale provides an option to measure trait mindfulness.
