When good pain turns bad

Classically, pain is viewed as being mediated solely by neurons. However, recent research has shown that activated glial cells (astrocytes and microglia) within the spinal cord amplify pain. These nonneuronal cells play a major role in the creation and maintenance of pathological pain. Glia become activated by immune challenges (viral or bacterial infection) and by substances released by neurons within the pain pathway. Activated glia amplify pain by releasing proinflammatory cytokines. Taken together, research findings suggest a novel approach to human pain control that targets glia. In addition, it is likely that such glial-neuronal interactions are not unique to pain, but rather reflect a general rule of sensory processing.     

Personality correlates of the disposition towards interpersonal forgiveness: A Chinese perspective

T his paper presents the results of three studies that investigated the nature of forgiveness, its measurement, and personality correlates in the People's Republic of China (PRC). Study 1 involved in‐depth interviews with 27 PRC cultural scholars about the concept of forgiveness and factors influencing the tendency to forgive in Chinese philosophy and everyday life. The respondents supported the relevance of this concept for Chinese societies and were able to give examples both from classical Chinese texts and their own lives. However, they also considered that preserving group harmony was the main reason to forgive and discounted the personality or religious influences commonly reported in the Western literature. Study 2 reported the adaptation of a Western forgiveness questionnaire for use with PRC respondents. Study 3 involved administering this questionnaire together with measures of self‐esteem, anxiety, impression management, and culturally appropriate constructs of face, relationship orientation, and harmony to 336 college students and 432 teachers from the PRC. As predicted, it was the latter two constructs that had the strongest correlations with the tendency to forgive in both samples. It was concluded that, in the PRC, willingness to forgive is influenced largely by social solidarity needs rather than the individualistic personality variables or religiosity reported in Western research. We hypothesize that this is due to the collectivist nature of PRC society and the results may well generalize to other collectivist cultures.     

Personal Inadequacy and Intimacy Predictors of Men's Hostility Toward Women

In this study we examined social/personality and intimacy predictors of men's hostility toward women (HTW). The study was framed in terms of a projection model that suggests that men's feelings of inadequacy contribute to hostility toward women. The sample consisted of 172 college men. The strongest attitudinal predictors were measures of locus of control. These data support the feminist analysis of sexual violence as an issue of power and lend support to the proposed projection model in terms of perceived powerlessness. In addition, based on the projection model, intimacy predictors for best male friend and female romantic partner were examined. The strongest correlate of men's HTW was intellectual intimacy, which conceptually is more related to the idea of an egalitarian relationship than other aspects of intimacy and may be most inhibited in men who are hostile toward women's intimate relationships.     

You Need to Understand My Gender Role: An Empirical Test of Tannen's Model of Gender and Communication

In her popular book on gender differences in communication, Deborah Tannen proposed that women and men interpret messages along different dimensions (intimacy and control) and that these differing interpretations make intersex communication difficult. In the present study, we contrasted Tannen's model with a more complex model that incorporated gender role as a factor that influences the interpretations of messages. Causal modeling of data from questionnaires (N = 192) administered to predominately European American university students revealed stronger support for a complex model than for the basic model.     

Distress Over the Infidelity of a Child’s Spouse: A Crucial Test of Evolutionary and Socialization Hypotheses

Parents of undergraduates were asked whether they would be more distressed by the sexual or the emotional infidelity of their child’s partner. Comparing the responses of mothers and fathers may offer a rare, “crucial” instance in which evolutionary and socialization perspectives offer different predictions. Socialization theory, broadly conceived, predicts an effect for the gender of the parent: Consistent with their differing gender socialization histories, mothers should be more distressed by the emotional infidelity of their child’s partner, and fathers by the sexual infidelity of their child’s partner. In contrast, an evolutionary psychology approach predicts little or no effect for the sex of the parents: Both mothers and fathers should be more distressed by infidelities that pose a greater threat to their genetic interests. Results were largely consistent with the predictions derived from evolutionary psychology: Both mothers and fathers regarded sexual infidelity as more distressing when committed by a daughter–in–law than by a son–in–law, and emotional infidelity as more distressing when it involved a son–in–law rather than a daughter–in–law. Discussion centered on the theoretical implications of research that examines the behavior of those who are, genetically, one step removed from the sexual behavior of others, but still affected by the reproductive consequences of that behavior.     

Efficacy of dialectical behaviour therapy for adolescents

The current review provides a qualitative assessment of the efficacy of dialectical behaviour therapy (DBT) as adapted for adolescents. The aim was to assess the efficacy of DBT compared to usual methods in the treatment of adolescent mental health symptoms, inclusive of suicidal ideation and self‐harm. Computerised databases including Medline and PsycINFO were accessed and knowledgeable informants in the area of DBT were contacted. Inclusion criteria required the studies to be clinical trials on DBT provided to adolescents. Due to the requirements on research design only three studies were appropriate for review. The review focused on quality assessment of the current data, including investigation into the effects of selection bias, confounding variables, outcome measures and measurement errors. The data suggest that there is some evidence for DBT being effective in reducing symptoms of mental health, especially those consistent with borderline personality disorder. The resultant data, however, are of very poor quality, and as such the review addresses ways to improve the quality of research and offers suggestions for future research.
