Why introverts can't always tell who likes them: multitasking and nonverbal decoding

Despite personality theories suggesting that extraversion correlates with social skill, most studies have not found a positive correlation between extraversion and nonverbal decoding. The authors propose that introverts are less able to multitask and thus are poorer at nonverbal decoding, but only when it is a secondary task. Prior research has uniformly extracted the nonverbal decoding from its multitasking context and, consequently, never tested this hypothesis. In Studies 1-3, introverts exhibited a nonverbal decoding deficit, relative to extraverts, but only when decoding was a secondary rather than a primary task within a multitasking context. In Study 4, extraversion was found to correlate with central executive efficiency (r = .42) but not with storage capacity (r = .04). These results are discussed in terms of arousal theories of extraversion and the role of catecholamines (dopamine and norepinephrine) in prefrontal function.     

The Epidemiology of Homicide followed by Suicide: A Systematic and Quantitative Review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide‐suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide‐suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide‐suicide and other homicide but there was modest but significant association between rates of suicide and homicide‐suicide. Homicide‐suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide‐suicide.     

A Preliminary Examination of the Role of Emotion Differentiation in the Relationship Between Borderline Personality and Urges for Maladaptive Behaviors

Impulsive, maladaptive, and potentially self-damaging behaviors are a hallmark feature of borderline personality (BP) pathology. Difficulties with emotion regulation have been implicated in both BP pathology and maladaptive behaviors. One facet of emotion regulation that may be particularly important in the relation between BP pathology and urges for maladaptive behaviors is emotion differentiation. Over 1 day, 84 participants high (n?=?34) and low (n?=?50) in BP pathology responded to questions regarding state emotions and urges to engage in maladaptive behaviors using handheld computers, in addition to a measure of emotion-related difficulties controlling impulsive behaviors. Results revealed that individuals high in BP pathology reported greater emotion-related impulsivity as well as daily urges to engage in maladaptive behaviors. However, the association between BP group and both baseline emotion-related impulsivity and daily urges for maladaptive behaviors was strongest among individuals who had low levels of positive emotion differentiation. Conversely, negative emotion differentiation did not significantly moderate the relationships between BP group and either emotion-related difficulties controlling impulsive behaviors or state urges for maladaptive behaviors. Limitations to the present study include the reliance upon an analogue sample and the relatively brief monitoring period. Despite limitations, these results suggest that, among individuals with high BP pathology, the ability to differentiate between positive emotions may be a particularly important target in the reduction of maladaptive behaviors.     

Interpersonal Assessment of Borderline Personality Disorder: Preliminary Findings

We examined the reliability and validity of scores on an interpersonal measure of borderline personality disorder (BPD). Ratings on the Interpersonal Measure of Borderline Personality Disorder (IM–B) were based on nonverbal behaviors and interpersonal interactions occurring during clinical interviews with 276 adults. Scores on the IM–B exhibited good reliability. IM–B scores also displayed expected patterns of associations with scores on other measures of BPD, as well as with scores on measures of affective dysfunction, interpersonal pathology, and behavioral impairment associated with BPD, including indexes of maladaptive emotion regulation, interpersonal sensitivity, and self-harm. The pattern of associations for IM–B scores was quite similar to what would be expected for a dimensional measure of BPD symptoms. Scores on the IM–B were also associated with symptoms of disorders generally comorbid with BPD. Finally, IM–B scores contributed incrementally to the prediction of interpersonal dysfunction and suicidal ideation and behavior. Discussion focuses on implications for the assessment of BPD.     

Suicidality Among Chronically Homeless People with Alcohol Problems Attenuates Following Exposure to Housing First

This study is the first to document suicidality among chronically homeless people with alcohol problems (N = 134) and examine its trajectory following exposure to immediate, permanent, low‐barrier housing (i.e., Housing First). Suicidal ideation, intent, plans, and prior attempts were assessed at baseline and during a 2‐year follow‐up. Baseline suicidal ideation was over four times higher than in the general population. Two‐year, within‐subjects, longitudinal analyses indicated severity of suicidal ideation decreased by 43% from baseline to follow‐up. Significant decreases were also found for intent and clinical significance of ideation. No participants died by suicide during the 2‐year follow‐up.     

Perceptions of the Limitations of Confidentiality Among Chinese Mental Health Practitioners,Adolescents and Their Parents

The present study aims to (a) survey Chinese mental health professionals’ attitudes toward therapeutic confidentiality with adolescent patients in specific clinical situations, and (b) compare Chinese adolescents’ and parents’ beliefs about when most mental health professionals would breach confidentiality. A sample of 36 mental health practitioners, 152 parents, and 164 adolescents completed a survey to assess their opinions about when confidentiality should be breached in 18 specific clinical situations (e.g., an adolescent tells his or her therapist that he or she smoked a cigarette, had unprotected sex, or attempted suicide). Nearly half of the parents (46%) and adolescents (41%) and 78% of the therapists in our sample selected “yes” in response to the question of whether the principle of confidentiality applies to adolescents. However, 49% of parents indicated “no,” and 53% of adolescents indicated “not sure.” Compared to adolescents, parents were significantly more likely to believe that therapists would breach confidentiality for the high-breach-likelihood items. For the low-breach-likelihood items, adolescents and parents were significantly more likely than therapists to believe confidentiality should be breached. Results from this study provide data to inform the development, refinement, practical implementation, and communication of guidelines and recommendations specific to adolescents receiving psychotherapy in China.
