The prevalence and risk factors associated with self‐mutilation among opioid dependent cases and controls were determined, and the co‐occurrence of self‐mutilation and attempted suicide was examined. The prevalence of self‐mutilation among cases and controls did not differ significantly (25% vs. 23%, respectively), with gender differences identified among cases only. A number of risk factors were found to be associated with self‐mutilation, including borderline personality disorder, alcohol dependence, childhood sexual abuse, and multiple suicide attempts. Not only is self‐mutilation a clinically significant problem, but when combined with a history of attempted suicide, the psychological dysfunction observed is markedly high. 相似文献

AbstractThere exists a large body of work examining individual differences in the propensity to engage in reflective thinking processes. However, there is a distinct lack of empirical research examining the role of dispositional factors in these differences and understanding these associations could provide valuable insight into decision-making. Here, we examine whether individual differences in cognitive reflection are related to narcissism (excessive self-focused attention) and impulsiveness (trait-based lack of inhibitory control). Participants across three studies completed measures of narcissism, impulsiveness and cognitive reflection. Results indicate that grandiose and vulnerable narcissists differ in their performance on problem-solving tasks (i.e., Cognitive Reflection Test [CRT]) and preferences for intuitive thinking, as well as the degree to which they reflect on and understand their own thoughts and enjoy cognitively effortful activities. Additionally, though impulsiveness was significantly related to self-report measures of cognitive reflection (i.e., metacognitive reflection, metacognitive insight, and need for cognition), it showed no association with a behavioural measure of cognitive reflection (i.e., CRT scores). Our results suggest that certain individual differences in dispositional and personality characteristics may play important roles in the extent to which individuals engage in certain forms of reflective thinking. 相似文献

Most law enforcers and academic experts agree that the largest one-percent motorcycle clubs are a formof organized crime despite their origins as barroom brawlers. A few club goals related to the destruction of rival groups are more or less overtly criminal. Of greater concern to most observers is the manner in which these clubs provide a context for individuals with a high propensity for illegal activity to unite long enough to operate enterprises of varying levels of sophistication. Social isolation from the mainstream intensifies intra-group loyalties as it concentrates members' attention on the underworld. Bikers integrate their private and club lives in an manner that makes the distinction between club-sponsored and other activities problematic. The relationship of these enterprises to the club itself is often murky as is the line between their planned and spontaneous expressive crimes. 相似文献

A Markov grammar was developed to account for the sequence of conversational moves in discourse about transgressions. This discourse interrupts ongoing activity and functions to repair the social fabric when inappropriate or awkward behavior has attracted the attention of interactants. A corpus of 1248 such interchanges, obtained in 90 hr of observation in kindergarten through fourth grade classrooms, was the basis of the grammar. Beginning with theoretical assumptions about the canonical form of these interchanges, the process of grammar development was explicitly described and the direction given by pragmatic considerations (such as attaining a balance between parsimony and accuracy) was discussed. The resultant grammar accounted for 83% of the corpus and served as a framework within which age and context effects on the discourse were explored. Loglinear analyses of multiway contingency tables at each transition point in the grammar revealed that the presence vs absence of an adult in the interchange affected the relative preferences for different alternatives at one juncture, but that subjects' ages did not influence the sequencing of discourse as described by the model. The overall approach was considered in relation to the more traditional uses of Markov models and its strengths, weaknesses, and future promise for discourse analysis were discussed. 相似文献
