The relationship between ADHD symptoms and driving behavior in college students: The mediating effects of negative emotions and emotion control

Previous research has shown a relationship between attention deficit-hyperactivity disorder (ADHD) symptoms and driving anger and adverse driving outcomes. Moreover, adults with ADHD symptoms express their emotions in more aggressive ways, indicating a lack of emotion control. The present study surveyed 246 college students to examine the relationship among ADHD symptoms, negative emotions, emotion control, and driving anger and safe driving behavior. Mediating effects of negative emotions and emotional control on the relationship between ADHD symptoms and self-reported driving anger and safe driving behavior were also examined. Both negative emotions and emotion control were significant mediators of the relationship between ADHD symptoms and driving anger, but not safe driving behavior. Mediation was stronger for ADHD-Hyperactive/Impulsive symptoms than for ADHD-Inattention symptoms. These results may provide some insight on how to design training programs for individuals with ADHD symptoms to increase driving safety.     

The Negative Physical Self Scale: Initial development and validation in samples of Chinese adolescents and young adults

This research presents four studies on the initial development and validation of the 48-item Negative Physical Self Scale (NPS), a multidimensional measure of body image concerns for use with Chinese samples. In Study 1 (N = 1095), exploratory factor analyses identified five dimensions underlying the NPS (General Appearance, Facial Appearance, Shortness, Fatness, Thinness). In Study 2 (N = 1057), confirmatory factor analyses replicated this factor structure. In Studies 3 and 4, the validity of all NPS dimensions except Thinness Concern was supported via their patterns of relation with both objective physical characteristics/behaviors and other self-report measures of body image and general self worth. Because Chinese adolescents and young adults expressed relatively more concerns about General Appearance, Shortness, and Facial Appearance than about Fatness, the NPS may have greater utility for assessing body image disturbances in China than existing measures that focus exclusively on general body satisfaction and body size/weight.     

The costs of today’s jobs: Job characteristics and organizational supports as antecedents of negative spillover

This study examined job characteristics and organizational supports as antecedents of negative work-to-nonwork spillover for 1178 U.S. employees. Based on hierarchical regression analyses of 2002 National Study of the Changing Workforce data and O∗NET data, job demands (requirements to work at home beyond scheduled hours, job complexity, time and strain) had positive relationships, and job resources (autonomy and skill development) and organizational supports (flexible work arrangements and two work-life culture facets) had negative relationships to negative spillover, but not all relationships held when multiple predictors were examined. Organizational supports did not moderate relationships of job characteristics to negative spillover, and relative weights analysis indicated that job characteristics accounted for the majority of explained variance in negative spillover. The findings underscore the importance of job characteristics, and suggest that job characteristics and organizational supports both need to be considered when developing work-life policies intended to reduce employees’ negative work-to-nonwork spillover.     

Memory of pain and affect associated with migraine and non-migraine headaches

The main aims of this study were to assess memory of pain and pain-related affect in headache sufferers and to compare the pain memories of individuals who suffer from migraines and those who experience non-migraine headaches. A total of 313 women participated in the study, 86 of whom had a diagnosis of migraine headache. The women rated their state anxiety about having a headache, the intensity and unpleasantness of headache pain, and their emotions while actually experiencing a headache. Either three or six months later, the participants were asked to recall their state anxiety, the intensity and unpleasantness of pain, and the emotions they had felt. Regardless of the length of recall delay or migraine diagnosis, participants accurately remembered both pain intensity and unpleasantness. Together, recalled anxiety, experienced pain and recalled positive affect were the most important predictors of memories for headache, accounting for 41% and 37% of the total variance in recalled pain intensity and unpleasantness, respectively. However, participants overestimated recalled positive and negative affect. The effect of recalled affect on memory of headache, together with the overestimation of recalled affect, suggests that although memory of headache is accurate, it is influenced by distorted memories of affect.     

The distressed (Type D) and Five-Factor Models of personality in young,healthy adults and their association with emotional inhibition and distress

The distressed (Type D) personality (the combination of negative affectivity and social inhibition traits) has been associated with adverse health outcomes. This study investigated the validity of the Type D construct against the Five-Factor Model (FFM) of personality, and its association with emotional control and distress. In total 498 university students (mean age 28.9 ± 8.4 years) completed the Type D scale (DS14), and measurements for the FFM of personality, emotional control, anxiety, depression and stress. The construct validity of the Icelandic DS14 was confirmed. The Type D components negative affectivity and social inhibition were strongly associated with neuroticism and extraversion of the FFM (r = 0.82 and r = −0.67, respectively). Negative affectivity also correlated with rehearsal/rumination (r = 0.58) and social inhibition with emotional inhibition (r = 0.54), indicative of emotional control. Type D personality (40% of sample) was associated with higher levels of anxiety, depression and stress. The Type D personality components were associated with the FFM of personality, emotional control and emotional distress. Importantly, social and emotional inhibition were closely related, providing novel information about the presence of emotional inhibition within the social inhibition trait.     

Anxiety sensitivity and intolerance of uncertainty: Evidence of incremental specificity in relation to health anxiety

Anxiety sensitivity (AS) reflects the fear of arousal-related sensations and intolerance of uncertainty (IU) represents the dispositional fear of the unknown. Within cognitive–behavioral models, AS and IU are individual difference variables considered central to the phenomenology of health anxiety. However, prior studies have cast doubt on whether both variables incrementally contribute to our understanding of health anxiety. Addressing limitations of these prior studies, the present study examined the incremental specificity of AS and IU as these two variables relate to health anxiety in a large medically healthy sample of community adults (N = 474). Both AS and IU incrementally contributed to the concurrent prediction of health anxiety beyond both negative affect and one another. However, within these analyses, the physical dimension of AS and the inhibitory dimension of IU were the only AS and IU dimensions to evidence incremental specificity in relation to health anxiety.     

Implicit theories of emotion shape regulation of negative affect

Implicit theories of emotion—assumptions about whether emotions are fixed (entity theory) or malleable (incremental theory)—have previously been shown to influence affective outcomes over time. We examined whether implicit theories of emotion also relate to the immediate regulation of negative affect. Consistent with our hypotheses, we found that the more students endorsed an entity theory of emotion, the more discomfort they reported while watching an aversive movie clip, the more they avoided affective stimuli in this movie clip, the more negative affect they reported after the clip, and the less likely they were to watch the same clip again to learn about its ending. These findings suggest that implicit theories of emotion might produce poor affective outcomes immediately as well as over time. They also offer insight into why some people avoid negative affect while others confront it.     

Cognitive-emotional dysfunction among noisy minds: Predictions from individual differences in reaction time variability

Mental noise can be defined as less reliable information processing. Individuals with high levels of mental noise are thought to be disadvantaged in cognitive, emotional, and behavioural realms. The present five studies (total N=298) investigated such potential disadvantages among normally functioning college undergraduates. Mental noise was operationalised in terms of the reaction time coefficient of variation (RTCV), a measure of RT variability that corrects for average levels of mental speed. Individuals with higher RTCV exhibited less effective cognitive control (Studies 1 and 5), less controlled behaviour (Study 2), and were more prone to negative emotional experiences (Study 3) and depressive symptoms (Study 4). Study 5 extended these results and found that individuals higher (versus lower) in RTCV were more adversely affected by their attentional lapses in daily life. Results converge on the idea that mental noise is an important individual difference dimension with multiple adverse correlates and consequences.     

Infant temperament and maternal parenting self-efficacy predict child weight outcomes

Relationships between infant negative reactivity and self-regulation, parenting self-efficacy, and child weight outcomes were examined. Greater observed negative reactivity predicted more child weight gain when mothers had lower parenting self-efficacy. Lower mother-reported self-regulation predicted a greater child weight status. Results highlight potential early risk/protective factors.     

Athletes' perceptions of how cognitive interference during competition influences concentration and effort

Abstract

This paper investigates athletes' perception of the relationship between cognitive interference and its effects on concentration and effort during sport performance. The sample consisted of 115 volleyball players that took part in a national university tournament. Three different kinds of thoughts were investigated: ‘performance worries’, ‘situation-irrelevant thoughts’, and ‘thoughts of escape’. Path analysis was used to examine the relationships. All kinds of thoughts were reported to be detrimental to concentration, whereas different patterns of associations emerged between different thoughts and subsequent effort. ‘Performance worries’ were reported to be related to increases in effort for athletes holding higher goal attainment expectancies and decreases in effort for athletes holding lower goal attainment expectancies. ‘Thoughts of escape’ were reported to be related to decreases in effort, while no significant relation between ‘situation irrelevant thoughts’ and effort emerged. Results stress the importance of further examining the role of interfering thoughts athletes experience during competition.
