The consequences of exposure to prenatal maternal anxiety for the development of child temperament were examined in a sample of 120 healthy, 2-year-old children. Prenatal maternal state and pregnancy-specific anxiety (PSA) were measured five times during pregnancy, and maternal state anxiety was measured again at 2 years post partum. Child temperament was measured at 2 years using the Early Childhood Behavior Questionnaire. The relationship between the trajectory of maternal anxiety across gestation and negative affectivity was evaluated using hierarchical linear growth curve modeling. Higher maternal PSA between 13 and 17 weeks of gestation was associated with increased negative temperament in the children. This association could not be explained by postnatal maternal anxiety, demographic, or obstetric factors. Prenatal maternal state anxiety was not associated with child temperament. These findings demonstrate that PSA early in gestation has a distinctive influence on the developing fetus.  相似文献

Motivational models emphasizing altered reinforcement sensitivity have been increasingly implicated in etiological accounts of attention-deficit/hyperactivity disorder (ADHD). Overactive behavioral approach tendencies are identified among these motivational models and are addressed within reinforcement sensitivity theory (RST). RST proposes that overactive behavioral approach is associated with over responsiveness to immediately reinforcing stimuli and results from an overactive appetitive motivational subsystem of the brain—the behavioral approach system. The current study tested the hypothesis that behavioral approach would be higher in a clinical sample of adults diagnosed with ADHD relative to a control group. Experimental and self-report measures of behavioral approach were administered. Behavioral approach was higher in the ADHD group across both methods of assessment. Effect size estimates fell within the medium to large range. Implications for how these findings might be incorporated into future ADHD models are discussed.  相似文献

In the wake of the First World War, a new form of commemoration emerged internationally, but in each case focused upon a new kind of national “hero”—the unknown soldier or warrior. The first instances appeared in France and Britain in 1920, followed by the United States in 1921, and Belgium in 1922. Other nations followed suit over the years, with the most recent WWI Unknown Soldier monument dedicated in 2004, in New Zealand. The motivational calculus of these national tombs was, of course, the massive number of combatant dead whose remains could not be identified. This paper takes up the two very different arguments composed by these commemorative sites. The first argument was directed to surviving family members and was articulated most explicitly by the French as a hypothetical enthymeme “this could be your husband, your father, your brother,” etc. The second argument has been directed to national and international collectives as a constitutive proclamation of legitimated nation-state or Empire Although this argument is particularly explicit in postcolonial gestures of independence on the part of former dominions of old empires, it was evident in even the earliest cases of the tombs of the unknown.  相似文献

Despite elevated rates of obsessive compulsive personality disorder (OCPD) in patients with obsessive compulsive disorder (OCD), no study has specifically examined comorbid OCPD as a predictor of exposure and ritual prevention (EX/RP) outcome. Participants were adult outpatients (n = 49) with primary OCD and a Yale-Brown Obsessive Compulsive Scale (YBOCS) total score ≥ 16 despite a therapeutic serotonin reuptake inhibitor dose for at least 12 weeks prior to entry. Participants received 17 sessions of EX/RP over 8 weeks. OCD severity was assessed with the YBOCS pre- and post-treatment by independent evaluators. At baseline, 34.7% of the OCD sample met criteria for comorbid DSM-IV OCPD, assessed by structured interview. OCPD was tested as a predictor of outcome both as a diagnostic category and as a dimensional score (severity) based on the total number of OCPD symptoms coded as present and clinically significant at baseline. Both OCPD diagnosis and greater OCPD severity predicted worse EX/RP outcome, controlling for baseline OCD severity, Axis I and II comorbidity, prior treatment, quality of life, and gender. When the individual OCPD criteria were tested separately, only perfectionism predicted worse treatment outcome, over and above the previously mentioned covariates. These findings highlight the importance of assessing OCPD and suggest a need to directly address OCPD-related traits, especially perfectionism, in the context of EX/RP to minimize their interference in outcome.  相似文献

This study evaluated the efficacy of methods of training community mental health providers (N = 132) in dialectical behavior therapy (DBT) distress tolerance skills, including (a) Linehan's (1993a) Skills Training Manual for Borderline Personality Disorder (Manual), (b) a multimedia e-Learning course covering the same content (e-DBT), and (c) a placebo control e-Learning course (e-Control). Participants were randomized to a condition, and the training took place in a highly structured and controlled learning environment. Assessments were completed at baseline, post-training, and 2, 7, 11, and 15 weeks following training. The results indicate that one or both of the active DBT conditions outperformed the control condition on all outcomes except motivation to learn and use the treatment. While clinicians preferred e-DBT over the Manual and found it more helpful and engaging, the active DBT conditions generally did not differ on the primary outcomes of knowledge and self-efficacy, with the exception that e-DBT significantly outperformed the Manual on knowledge at the 15-week follow-up. E-DBT also produced the highest rate of applying and teaching the newly learned skills in clinical practice. Overall, results from this study support the efficacy of e-Learning in disseminating knowledge of empirically supported treatments to clinicians, while also indicating that treatment manuals can be effective training tools.  相似文献

The authors examine the effects of poverty-related adversity on child development, drawing upon psychobiological principles of experiential canalization and the biological embedding of experience. They integrate findings from research on stress physiology, neurocognitive function, and self-regulation to consider adaptive processes in response to adversity as an aspect of children's development. Recent research on early caregiving is paired with research in prevention science to provide a reorientation of thinking about the ways in which psychosocial and economic adversity are related to continuity in human development.  相似文献

For collective action to evolve and be maintained by selection, the mind must be equipped with mechanisms designed to identify free riders--individuals who do not contribute to a collective project but still benefit from it. Once identified, free riders must be either punished or excluded from future collective actions. But what criteria does the mind use to categorize someone as a free rider? An evolutionary analysis suggests that failure to contribute is not sufficient. Failure to contribute can occur by intention or accident, but the adaptive threat is posed by those who are motivated to benefit themselves at the expense of cooperators. In 6 experiments, we show that only individuals with exploitive intentions were categorized as free riders, even when holding their actual level of contribution constant (Studies 1 and 2). In contrast to an evolutionary model, rational choice and reinforcement theory suggest that different contribution levels (leading to different payoffs for their cooperative partners) should be key. When intentions were held constant, however, differences in contribution level were not used to categorize individuals as free riders, although some categorization occurred along a competence dimension (Study 3). Free rider categorization was not due to general tendencies to categorize (Study 4) or to mechanisms that track a broader class of intentional moral violations (Studies 5A and 5B). The results reveal the operation of an evolved concept with features tailored for solving the collective action problems faced by ancestral hunter-gatherers.  相似文献

The objective of this study was to examine if and how two basic dimensions of temperament-behavioral inhibition system (BIS) and behavioral approach system (BAS) sensitivity-might interact with exposure to perceived parental affectionless control (AFC) to predict personality disorder (PD) symptomatology. Measures of BIS, BAS, AFC, and PD symptomatology were administered to a large nonclinical sample (n = 318). As predicted, exposure to AFC was positively associated with PD symptoms in general, BIS was positively associated with Cluster A and C symptoms, and BAS was positively associated with Cluster B symptoms. BIS and BAS were also found to interact with each other to predict Cluster B symptomatology. In addition, BIS, BAS, and maternal AFC interacted to predict Cluster A symptomatology. In the latter case, it was found that individuals who reported high BIS, high BAS, and high maternal AFC reported the highest overall level of Cluster A symptoms.  相似文献

Summary

The findings of a survey of the involvement of staff in group activities within a large psychiatric hospital are presented. Over two hundred regular group meetings were being held, excluding ward-rounds and business meetings. There was a wide variation in the type and structure of the groups, the purpose and theoretical underpinning of many of which were unclear to the participants. It is suggested that this lack of clarity reflects the fact that the original therapeutic aims have been subverted in the service of institutionalised defences against anxiety. To be therapeutically effective, groups need clear leadership, good supervision and well-defined aims.  相似文献
