Changes in ecological momentary assessment reported affect associated with episodes of nonsuicidal self-injury

Although emotion regulation deficits have been frequently implicated in the incidence of nonsuicidal self-injurious behavior (NSSI), no research to date has examined in vivo change of affect associated with real-world NSSI behavior. The present study employed Ecological Momentary Assessment (EMA) to assess change in affect associated with episodes of experienced NSSI in a sample of 36 college students with a self-reported history of NSSI. Results indicated that individuals who reported NSSI behavior over the course of the study experienced increases in negative affect prior to an episode of NSSI that peaked during the episode and faded gradually in the hours following the episode, with affect change roughly approximating a quadratic curve. These changes in affect were detected only at times in which individuals engaged in NSSI and were absent for individuals who did not report NSSI over the course of the study. Moreover, changes in negative affect associated with NSSI were, on average, detectable hours prior to the NSSI event. These findings suggest that episodes of NSSI may be predicted through a careful examination of affect change long before actual NSSI behavior occurs.     

Callous-unemotional traits and conduct problems in the prediction of conduct problem severity,aggression, and self-report of delinquency

The role of callous-unemotional (CU) traits and conduct problems in predicting conduct problem severity, severity and type of aggression, and self-reported delinquency at a 1-year follow-up was investigated in a sample of 98 children (mean age 12.43; SD = 1.72) recruited from a community-wide screening. Children with both CU traits and conduct problems had a greater number and variety of conduct problems at follow-up than children who at the screening had high levels of conduct problems alone. However, this poorer outcome for children with CU traits could largely be accounted for by differences in initial level of conduct problem severity. Children with CU traits and conduct problems were also at risk for showing higher levels of aggression, especially proactive aggression, and self-reported delinquency. Importantly, these outcomes could not be solely explained by initial level of conduct problem severity. Finally, CU traits predicted self-reported delinquency in some children who did not initially show high levels of conduct problems and this predictive relationship seemed to be strongest for girls in the sample who were high on CU traits but who did not show significant conduct problems.     

Examining the relationship between emotion regulation deficits and borderline personality disorder features: A daily diary study

This study used a six-day daily diary methodology to precisely specify the nature of emotion regulation deficits associated with borderline personality disorder (BPD) features. Three possibilities were explored: that BPD features are associated with (1) the overall underuse of emotion regulation strategies; (2) the overuse of dysfunctional and the underuse of functional strategies; and (3) the lower perceived effectiveness of emotion regulation strategies. One hundred and fifty-four undergraduate participants completed self-report measures of BPD feature severity, and then reported their daily negative emotional intensity, whether or not they used various emotion regulation strategies, and whether or not the strategies that they used were effective across a six-day period. Higher BPD features were associated with (a) higher total frequency use of emotion regulation strategies; (b) higher frequency use of dysfunctional and functional emotion regulation strategies; and (c) less self-reported effectiveness of functional strategies. BPD features may be characterized by increased attempts to regulate emotions, without corresponding increases in perceived effectiveness.     

Callous-unemotional traits and empathy deficits: Mediating effects of affective perspective-taking and facial emotion recognition

Although empathy deficits are thought to be associated with callous-unemotional (CU) traits, findings remain equivocal and little is known about what specific abilities may underlie these purported deficits. Affective perspective-taking (APT) and facial emotion recognition may be implicated, given their independent associations with both empathy and CU traits. The current study examined how CU traits relate to cognitive and affective empathy and whether APT and facial emotion recognition mediate these relations. Participants were 103 adolescents (70 males) aged 16–18 attending a residential programme. CU traits were negatively associated with cognitive and affective empathy to a similar degree. The association between CU traits and affective empathy was partially mediated by APT. Results suggest that assessing mechanisms that may underlie empathic deficits, such as perspective-taking, may be important for youth with CU traits and may inform targets of intervention.     

Self-esteem in patients with borderline and avoidant personality disorders

This study compared self-esteem in patients with avoidant personality disorder (APD) and borderline personality disorder (BPD). Patients diagnosed with one or more personality disorders answered the questionnaire Index of Self Esteem as part of a comprehensive evaluation within the setting of a treatment trial. Our hypotheses were that (1) both patients with APD and patients with BPD would report low levels of self-esteem, (2) patients with APD would report lower self-esteem than patients with BPD. We further expected that (3) patients with higher levels of depression would report lower levels of self-esteem, but that (4) both borderline and avoidant personality pathology would contribute to explained variance in self-esteem beyond what would be accounted for by depression. All of our hypotheses were supported. The results from our study showed a significant difference in self-esteem level between the two personality disorders, patients with APD reporting lower self-esteem than patients with BPD. Subjects with both disorders were measured to have self-esteem levels within the range that presumes clinical problems. Self-esteem represents an important quality of subjective experience of the self, and the study of self-esteem in PDs can offer new and important knowledge of PDs as self-pathology.     

Reasons for suicide attempts and nonsuicidal self-injury in women with borderline personality disorder

Self-reported reasons for suicide attempts and nonsuicidal self-injury were examined using the Parasuicide History Interview within a sample of chronically suicidal women meeting criteria for borderline personality disorder (N = 75). Overall, reasons given for suicide attempts differed from reasons for nonsuicidal self-injury. Nonsuicidal acts were more often reported as intended to express anger, punish oneself, generate normal feelings, and distract oneself, whereas suicide attempts were more often reported as intended to make others better off. Almost all participants reported that both types of parasuicide were intended to relieve negative emotions. It is likely that suicidal and nonsuicidal parasuicide have multiple intents and functions.     

Contributions of psychopathic, narcissistic, Machiavellian, and sadistic personality traits to juvenile delinquency

The aim of this study was to assess the relative contributions of psychopathic, narcissistic, Machiavellian, and sadistic traits to delinquent behaviors in adolescents. Participants were 615 high-school students who completed self-report questionnaires. Psychopathic, narcissistic, Machiavellian, and sadistic traits were moderately correlated suggesting they may be overlapping but distinct constructs. Hierarchical multiple regression analyses were conducted to control for other socio-familial or psychopathological risk factors. Psychopathic and sadistic traits were independent predictors of delinquent behaviors in boys only. These findings suggest the importance of studying the role of sadistic traits in juvenile delinquency.     

Emotion Differentiation as a Protective Factor Against Nonsuicidal Self-Injury in Borderline Personality Disorder

Evidence that nonsuicidal self-injury (NSSI) serves a maladaptive emotion regulation function in borderline personality disorder (BPD) has drawn attention to processes that may increase risk for NSSI by exacerbating negative emotion, such as rumination. However, more adaptive forms of emotion processing, including differentiating broad emotional experiences into nuanced emotion categories, might serve as a protective factor against NSSI. Using an experience-sampling diary, the present study tested whether differentiation of negative emotion was associated with lower frequency of NSSI acts and urges in 38 individuals with BPD who reported histories of NSSI. Participants completed a dispositional measure of rumination and a 21-day experience-sampling diary, which yielded an index of negative emotion differentiation and frequency of NSSI acts and urges. A significant rumination by negative emotion differentiation interaction revealed that rumination predicted higher rates of NSSI acts and urges in participants with difficulty differentiating their negative emotions. The results extend research on emotion differentiation into the clinical literature and provide empirical support for clinical theories that suggest emotion identification and labeling underlie strategies for adaptive self-regulation and decreased NSSI risk in BPD.     

Psychopathology, childhood trauma, and personality traits in patients with borderline personality disorder and their sisters

The aim of this study was to document and compare adverse childhood experiences, and personality profiles in women with borderline personality disorder (BPD) and their sisters, and to determine how these factors impact current psychopathology. Fifty-six patients with BPD and their sisters were compared on measures assessing psychopathology, personality traits, and childhood adversities. Most sisters showed little evidence of psychopathology. Both groups reported dysfunctional parent-child relationships and a high prevalence of childhood trauma. Subjects with BPD reported experiencing more emotional abuse and intrafamilial sexual abuse, but more similarities than differences between probands and sisters were found. In multilevel analyses, personality traits of affective instability and impulsivity predicted DIB-R scores and SCL-90-R scores, above and beyond trauma. There were few relationships between childhood adversities and other measures of psychopathology. Sensitivity to adverse experiences, as reflected in the development of psychopathology, appears to be influenced by personality trait profiles.     

Emotional states preceding and following acts of non-suicidal self-injury in bulimia nervosa patients

Bulimia nervosa and non-suicidal self-injury (NSSI) co-occur at high rates, and both have been conceptualized as maladaptive emotion regulation strategies. Treatments focusing on emotion regulation have been designed for both problem behaviors, yet, there exists very little research examining the temporal emotional states surrounding acts of NSSI. Using ecological momentary assessment (EMA) methodology, the current study examined the temporal association between positive and negative emotional states prior to and consequent to acts of NSSI within a subset of bulimia nervosa patients. Results indicate significant increases in negative affect, and decreases in positive affect, prior to an NSSI act. Post-NSSI, positive affect significantly increased while negative affect remained unchanged. The findings offer partial support for an emotion regulation paradigm to understanding NSSI within bulimic populations and implications for treatment are discussed.     

Gender differences in implicit and explicit personality traits

This article investigates gender differences in implicit and explicit measures of the Big Five traits of personality. In a high-powered study (N = 14,348), we replicated previous research showing that women report higher levels of Agreeableness, Conscientiousness, Extraversion and Neuroticism. For implicit measures, gender differences were much smaller for all, and opposite in sign for Extraversion. Somewhat higher levels of implicit Neuroticism and Agreeableness were observed in women, and somewhat higher levels of implicit Extraversion and Openness were observed in men. There was no gender difference in implicit Conscientiousness. A possible explanation is that explicit self-concepts partly reflect social norms and self-expectations about gender roles, while implicit self-concepts may mostly reflect self-related experiences.     

Types of Aggression,Responsiveness to Provocation,and Callous-unemotional Traits in Detained Adolescents

The present study investigated differences in the behavioral and psychophysiological responses to provocation and in the level of callous-unemotional traits in boys exhibiting different patterns of aggression. Eighty-five boys (ages 13-18) in a juvenile detention center played a competitive computer task against a hypothetical peer who provided low and high levels of provocation. Youth high on both self-reported reactive and proactive aggression showed different behavioral responses to provocation than youth high on only reactive aggression. Specifically, the combined group showed high levels of aggressive responses without any provocation, whereas the group high on reactive aggression showed an increase in aggressive responding to low provocation. Further, results revealed a trend for the combined group to show lower levels of skin conductance reactivity to low provocation if they were also high on callous-unemotional traits.     

Co-occurrence of non-suicidal self-injury and impulsivity in extreme weight conditions

The aims of the present study were to determine the prevalence of non-suicidal self-injury (NSSI) in different eating disorder (ED) groups and morbid obesity, and to investigate whether NSSI in different ED/obesity groups co-occur with impulsivity. We assessed 535 individuals (365 ED and 170 obese patients) by means of a single item assessing lifetime NSSI and the Barratt Impulsivity Scale, which measures different dimensions of impulsivity. The results showed that 19.1% of the ED patients engaged in at least one act of NSSI during their life-time. NSSI was more prevalent in Bulimia Nervosa, Binge Eating Disorder, Eating Disorder Not Otherwise Specified compared to Anorexia Nervosa, Restrictive type and morbid obesity. Finally, ED/obese patients who engaged in NSSI scored significantly higher on the attentional, motor and non-planning subscales than patients without NSSI. The implications of these findings for the treatment of NSSI in binge/purging ED patients are discussed.     

Non-suicidal self-injury and identity distress in Flemish adolescents: Exploring gender differences and mediational pathways

There is an increasing amount of research that examines non-suicidal self-injury (NSSI) in relation to identity formation in adolescents. However, little or no research to date has explored associations between NSSI and identity distress in specific domains. To address this shortcoming, we assessed NSSI, identity distress, anxiety, and depression using self-report questionnaires in 568 high school students. Gender differences in NSSI were found with lifetime prevalence of NSSI being twice as high in females as compared to males. Gender differences in terms of identity domains were also significant; adolescent females showed higher levels of distress in the identity domains of career goals, friendship, and group loyalties as compared to males. Adolescents engaging in NSSI showed higher distress in domains of long-term goals, friendship, sexual orientation and behavior, values and beliefs. Results indicated that it was not distress in specific domains as such but the impairment due to daily impact of identity distress that explained additional variance in lifetime prevalence of NSSI above and beyond gender, age, depression, and anxiety. We also demonstrated that gender differences in lifetime prevalence of NSSI were mediated by differences in such identity impairment. Clinical implications of these findings are discussed.     

Emotional responding in NSSI: examinations of appraisals of positive and negative emotional stimuli,with and without acute stress

Non-suicidal self-injury (NSSI) is commonly used by young adults to regulate emotional responses. Yet, experimental examination of how people who self-injure appraise and respond to emotional stimuli is limited. We examined appraisals of, and responses to, emotive images in young adults who did and did not self-injure, and assessed whether these were impacted by exposure to a stressor. Study 1 (N?=?51) examined whether participants differed in their appraisals of emotional images. Study 2 (N?=?78) assessed whether appraisals of images changed after exposure to the Trier Social Stress Test. Ratings of emotional valence and arousal were collected in both studies; skin conductance was measured as an indicator of physiological arousal in Study 2. In Study 1 participants reporting NSSI rated positively valenced images as less pleasant than participants not reporting NSSI. In Study 2, after acute stress, participants reporting NSSI displayed dampened physiological reactions to positive images whereas participants who did not self-injure displayed heightened physiological reactions to these and rated them as more pleasant. Individuals who self-injure seem less able to engage in strategic mood repair after exposure to stress compared to people who do not self-injure.     

Schizotypal personality traits and atypical lateralization in motor and language functions

Atypical cerebral lateralization in motor and language functions in regard to schizotypal personality traits in healthy populations, as well as among schizophrenic patients, has attracted attention because these traits may represent a risk factor for schizophrenia. Although the relationship between handedness and schizotypal personality has been widely examined, few studies have adopted an experimental approach. This study consisted of three experiments focusing on motor and language functional lateralization in regard to schizotypal personality in the absence of mental illness: line-drawing, finger tapping, and a semantic go/no-go task. The results suggested that positive schizotypal personality might be related to functional non-lateralization in regard to at least some functions (e.g., spatial motor control and semantic processing in the present study). Subjects with high schizotypal personality traits performed equally with their right and left-hands in the line-drawing task and they reacted equally with their right and left-hands in a semantic go/no-go task involving semantic auditory stimuli presented in both ears. However, those low in schizotypal personality traits showed typical lateralization in response to these tasks. We discuss the implications of these findings for schizotypal atypical lateralization.     

Structural models of psychotherapy groups and their effect on inpatients with borderline personality disorders: Patients' perceptions

This research compares the way in which various group structural models affect self-understanding, interpersonal relationships and catharsis in hospitalized patients with borderline personality disorders. Each of the models is characterized by a different combination of group focus and leadership style. Three psychotherapy groups were chosen as paradigms: the dynamic psychotherapy group; the therapeutic games group, and psychodrama group. Sixty three inpatients with borderline personality disorders participated in the study. The one-way ANOVA yielded significant differences between the group models. Results of the post-hoc t-test showed that the dynamic and the games groups were perceived by the patients as more beneficial than psychodrama.
