The functions of deliberate self-injury: a review of the evidence.

Deliberate self-injury is defined as the intentional, direct injuring of body tissue without suicidal intent. The present article reviews the empirical research on the functions of self-injury. This literature includes self-reports of reasons for self-injuring, descriptions of the phenomenology of self-injury, and laboratory studies examining the effects of self-injury proxies on affect and physiological arousal. Results from 18 studies provide converging evidence for an affect-regulation function. Research indicates that: (a) acute negative affect precedes self-injury, (b) decreased negative affect and relief are present after self-injury, (c) self-injury is most often performed with intent to alleviate negative affect, and (d) negative affect and arousal are reduced by the performance of self-injury proxies in laboratory settings. Studies also provide strong support for a self-punishment function, and modest evidence for anti-dissociation, interpersonal-influence, anti-suicide, sensation-seeking, and interpersonal boundaries functions. The conceptual and empirical relationships among the different functions remain unclear. Future research should address the measurement, co-variation, clinical correlates, and treatment implications of different functions.

Meta-perception for pathological personality traits: do we know when others think that we are difficult?

The self allows us to reflect on our own behavior and to imagine what others think of us. Clinical experience suggests that these abilities may be impaired in people with personality disorders. They do not recognize the impact that their behavior has on others, and they have difficulty understanding how they are seen by others. We collected information regarding pathological personality traits--using both self and peer report measures--from groups of people who knew each other well (at the end of basic military training). In previous papers, we have reported that agreement between self-report and peer-report is only modest. In this paper, we address the question: Do people know that others disagree with their own perceptions of themselves? We found that expected peer scores predicted variability in peer report over and above self-report for all 10 diagnostic traits. People do have some incremental knowledge of how they are viewed by others, but they do not tell you about it unless you ask them to do so; the knowledge is not reflected in ordinary self-report data. Among participants who expect their peers to describe them as narcissistic, those who agree with this assessment are viewed as being less narcissistic by their peers than those who deny being narcissistic. It therefore appears that insight into how one is viewed by others can moderate negative impressions fostered by PD traits.

Deliberate self-harm in a nonclinical population: prevalence and psychological correlates.

OBJECTIVE: Research on deliberate self-harm (intentionally injuring oneself without suicidal intent) has focused on clinical and forensic populations. Studying only these populations, which typically have serious psychopathology, may lead to inflated estimates of the association between self-harm and psychiatric disorder, as well as of the prevalence of deliberate self-harm. The present study investigated the prevalence and correlates of deliberate self-harm in a large group of nonclinical subjects. METHOD: Participants were 1,986 military recruits, 62% of whom were men, who were participating in a study of peer assessment of personality traits and pathology. Individuals who did and did not report a history of self-harm were compared on measures of personality and psychopathology. RESULTS: Approximately 4% of the participants reported a history of deliberate self-harm. Compared with participants without a history of deliberate self-harm, self-harmers scored higher on self- and peer-report measures of borderline, schizotypal, dependent, and avoidant personality disorder symptoms and reported more symptoms of anxiety and depression. Item-level analyses indicated that peers viewed self-harmers as having strange and intense emotions and a heightened sensitivity to interpersonal rejection. CONCLUSIONS: About one of every 25 members of a large group of relatively high-functioning nonclinical subjects reported a history of self-harm. Self-harmers had more symptoms of several personality disorders than non-self-harmers, and their performance across measures suggested that anxiety plays a prominent role in their psychopathology. Future research should investigate whether psychotherapies or psychiatric medications known to reduce symptoms of anxiety can be effective in treating deliberate self-harm.

Gender role and personality disorders.

Many researchers have hypothesized relationships between personality disorders and gender role (i.e., masculinity and femininity). However, research has not addressed if people who are masculine or feminine more often meet the criteria for personality disorders. The present study examined whether college students (N = 665, 60% women) higher in masculinity or femininity more often exhibited features of the 10 DSM-IV personality disorders. Feminine men exhibited more features of all the personality disorders except antisocial. Dependent traits were associated with higher femininity and lower masculinity. Antisocial traits were associated with masculinity. Both men and women who typically behaved consistent with their gender had more narcissistic and histrionic features, whereas participants who typically behaved unlike their gender had more features of the Cluster A personality disorders.
