Personality characteristics associated with aerobic exercise in adult males

Using an index of aerobic conditioning 23 adult male exercisers and 23 nonexercisers were identified. During individual interviews with each subject basic demographic data were obtained and blood pressure, resting pulse rate, and body fat were measured. All subjects completed Form A of the Sixteen Personality Factor Questionnaire (16PF). Statistically significant differences occurred on six primary factors and four Secondary dimensions of the 16PF. In comparison to the inactive subjects the exercisers, all of whom were joggers or runners, were more reserved, expedient, suspicious, forthright, liberal, and self-sufficient on the primary traits, and were more alert and independent, less discreet, and evidenced lower super-ego strength on the broader secondary patterns. The statistically significant training effects were lower pulse rate and less body fat, but did not include blood pressure.     

Instructors' and classroom characteristics associated with exercise enjoyment by females

The purpose of this study was to examine the relationships between exercise enjoyment and participant's perceptions of selected characteristics of the exercise instructor and exercise class. Women (N=296) attending aerobics classes at a university fitness center were surveyed. Analysis yielded significant correlations among exercise enjoyment and the four characteristics of instructor and five for classroom. Correlations ranged from .16 to .32. Stepwise regression analysis was also conducted. Three of the nine characteristics entered into the model: (1) instructor's personal fitness, (2) instructor's ability to communicate instruction, and (3) liking of other participants in the class. The three variables combined accounted for only 17% of the variability for enjoyment of exercise.     

Personality characteristics of androgynous and sex-typed females

Personality characteristics of androgynous and sex-typed females identified by the gem Sex-Role Inventory were studied using the California Psychological Inventory. The results indicated that sex-typed females showed personality characteristics associated with traditional sex-role stereotypes while androgynous females showed both masculine nd feminine characteristics. There was an indication that androgynous and masculine females were better adjusted socially than feminine or undifferentiated females.     

Personality characteristics of young adult migraineurs

Young adults with migraine headaches and nonmigraineurs were compared by means of two questionnaire batteries (the 16 P-F and PRF) and sets of specific measures focused on stimulation-seeking and independence. A number of low correlations were obtained but overall, results tend to contradict the existence of a "migraine personality" as a measureable entity.     

Personality characteristics associated with susceptibility to false memories

This study examined whether certain personality characteristics are associated with susceptibility to false memories. Participants first answered questions from the Myers-Briggs Type Indicator in order to measure various personality characteristics. They then watched a video excerpt, the simulated eyewitness event. They were next encouraged to lie about the videotaped event during an interview. A week later, some participants recognized confabulated events as being from the video. Two personality characteristics in particular--the introversion-extroversion and thinking-feeling dimensions--were associated with susceptibility to false memories.     

Acute psychological benefits of aerobic exercise: a field study into the effects of exercise characteristics

Eighty volunteers were tested in their natural exercise environment consisting of a fitness centre they regularly attended. Half of the sample exercised on a stationary bicycle, the other half on a treadmill. All participants filled in the Exercise-Induced Feeling Inventory before and after their 20 min of exercise that was performed at self-selected workload. The results revealed that exercise intensity and the other parallel measures like heart rate, perceived exercise intensity and estimates of burned calories were higher in participants who ran in contrast to those who cycled. There were no differences in self-reports of enjoyment of the exercise sessions and in the psychological improvements from pre- to post-exercise between the groups. It is concluded that significant psychological improvements occur even after a 20-min bout of exercise and these changes are independent of the workload or exercise intensity.     

Personality characteristics associated with romantic attachment: a comparison of interview and self-report methodologies

This study compared the personality attributes associated with self-report versus interview assessment of romantic attachment. Twenty-three-year-olds (N = 83) completed the Romantic Attachment Interview, the Experiences in Close Relationship Inventory, and measures of response bias, self-enhancement, and self-insight. Five psychologists evaluated the participants' personality. Although both self-report and interview assessment were related to attachment-relevant personality attributes, interview assessment was slightly more likely to explain unique variance in personality, especially regarding intrapsychic attributes. Self-enhancement was negatively related to secure attachment and positively related to dismissing attachment. The opposite pattern emerged for self-insight. A subgroup of 12 vulnerable individuals who described themselves as securely attached on self-report was judged as dismissing according to interview assessment. These individuals scored low on self-insight and high on self-enhancement and psychological vulnerability. The results are discussed with reference to the relative strengths of different measures of romantic attachment and relations among dismissing attachment, self-enhancement, and narcissism.     

Childhood maltreatment associated with adult personality disorders: findings from the Collaborative Longitudinal Personality Disorders Study

Adverse childhood experiences such as abuse and neglect are frequently implicated in the development of personality disorders (PDs); however, research on the childhood histories of most PD groups remains limited. In this multisite investigation, we assessed self-reported history of abuse and neglect experiences among 600 patients diagnosed with either a PD (borderline, schizotypal, avoidant, or obsessive-compulsive) or major depressive disorder without PD. Results indicate that rates of childhood maltreatment among individuals with PDs are generally high (73% reporting abuse; 82% reporting neglect). As expected, borderline PD was more consistently associated with childhood abuse and neglect than other PD diagnoses. However, even when controlling for the effect of borderline PD, other PD diagnoses were associated with specific types of maltreatment.     

Mood alterations in mindful versus aerobic exercise modes

The results of most recent studies have generally indicated an improvement in mood after participation in aerobic exercise. However, only a few researchers have compared mindful modes of exercise with aerobic exercise to examine the effect of 1 single session of exercise on mood. In the present study, the authors assessed state anxiety, depressive mood, and subjective well-being prior to and following 1 class of 1 of 4 exercise modes: yoga, Feldenkrais (awareness through movement), aerobic dance, and swimming; a computer class served as a control. Participants were 147 female general curriculum and physical education teachers (mean age = 40.15, SD = 0.2) voluntarily enrolled in a 1-year enrichment program at a physical education college. Analyses of variance for repeated measures revealed mood improvement following Feldenkrais, swimming, and yoga but not following aerobic dance and computer lessons. Mindful low-exertion activities as well as aerobic activities enhanced mood in 1 single session of exercise. The authors suggest that more studies assessing the mood-enhancing benefits of mindful activities such as Feldenkrais and yoga are needed.     

Personality and self-determination of exercise behaviour

There is extensive evidence that personality traits are associated with health-related behaviours, but less evidence regarding the underlying mechanisms. In this study, we examined the relationships between personality and self-determination of exercise behaviour. Users of a sports centre completed personality scales (the NEO Five Factor Inventory supplemented with the Eysenck Personality Questionnaire Psychoticism scale) and exercise self-determination scales (Behavioural Regulation in Exercise Questionnaire which measures extrinsic, introjected, identified and intrinsic forms of regulation). Analyses were restricted to 182 individuals in the maintenance stage of exercise participation. Partial correlation analysis was used to examine the relationships between each personality scale and the self-determination scales, controlling for other personality scales, gender and age. Neuroticism was associated with more introjected regulation, extraversion with more identified and intrinsic regulation, openness with less external regulation, conscientiousness with less external regulation and more intrinsic regulation, and psychoticism with more external regulation. Relating these findings to self-determination theory (Deci & Ryan, 2000), it is speculated that extraverted individuals are able to feel self-determined because exercise can satisfy the need for relatedness, conscientious individuals because exercise can satisfy the need for competence. Furthermore, conscientious individuals may have greater wherewithal to advance along the continuum of behavioural regulation.     

Acute effects of aerobic exercise on mood

Thirty-two female students participated in a single-session experiment during which they carried out two 8-min trials of high-intensity exercise and two 8-min trials of low-intensity exercise. One high- and one low-exercise trial were accompanied by music; the other two trials were accompanied by metronome. Mood was assessed with a modification of the Profile of Mood States before and immediately after each trial. The purpose of the experiment was disguised to reduce the influence of subject expectations on mood responses. Participants were divided into fit and unfit groups based on heart rate responses during high-exercise trials. Overall, high-intensity exercise led to increases in tension/anxiety and fatigue, whereas positive mood changes (vigor and exhilaration) were seen following low-intensity exercise only. No group differences in mood responses were observed. Explanations of these results are considered in light of other literature concerning the acute effects of exercise on mood.     

Effects of aerobic exercise on anxiety sensitivity

Anxiety sensitivity is a known precursor to panic attacks and panic disorder, and involves the misinterpretation of anxiety-related sensations. Aerobic exercise has been shown to reduce generalized anxiety, and may also reduce anxiety sensitivity through exposure to feared physiological sensations. Accordingly, 54 participants with elevated anxiety sensitivity scores completed six 20-min treadmill exercise sessions at either a high-intensity aerobic ( n = 29 ) or low-intensity ( n = 25 ) level. Self-ratings of anxiety sensitivity, fear of physiological sensations associated with anxiety, and generalized anxiety were obtained at pre-treatment, post-treatment, and one-week follow-up. Results indicated that both high- and low-intensity exercise reduced anxiety sensitivity. However, high-intensity exercise caused more rapid reductions in a global measure of anxiety sensitivity and produced more treatment responders than low-intensity exercise. Only high-intensity exercise reduced fear of anxiety-related bodily sensations. The implications of these findings are discussed.
