This study explores longitudinally a four-factor structure of pathological personality trait dimensions (PPTDs) to examine both its structural stability and intra-individual changes among PPTDs over time. Personality Disorder (PD) scales of the Millon Clinical Multiaxial Inventory-III were administered to 361 low-income women with various psychiatric conditions (drug dependence, depression), who were followed in a two-wave study over 5-years. Cross-sectional and longitudinal factor analyses outlined a robust factorial structure of PPTDs, extrinsically invariant over time, representing Negative Emotionality, Introversion, Antagonism and Impulsivity. Despite moderate rank-order stability in the PPTDs, results also indicated substantial intra-individual variability in the degree and direction of change, consistent with trajectories of change in participants’ clinical diagnoses. Results are discussed in light of current debates on the structure and dynamic of pathological personality. 相似文献

This article combines a constructivist grounded theory approach with a focus on structuration theory to propose a new mental model for understanding motivation in the context of solving complex problems in contemporary business-to-business (B2B) settings. This study uses the interpretative tradition of qualitative research to conduct in-depth interviews of 24 B2B sales professionals and subsequently analyze their lived experiences. Findings indicate that intrinsic motivation stems attitudinally from a need to foster an identity of helping customers, introducing a concept called “interpersonal identification” with customers. That identity motivates the development of more cognitively intense sales proposals using a more holistic proposal development process – referred to herein as “systems-savvy selling.” While interpersonal relationships have long been components of B2B relationships, this study challenges laypeople’s stereotypes of salespeople who use interpersonal relationships to improve business outcomes. Instead, systems-savvy selling helps salespeople build interpersonal relationships and use business outcomes as feedback to strengthen interpersonal relationships and their identification with customers. Unexpectedly, it also finds that dual-role sales managers, who have roles both in selling and managing, confront a paradox of self versus others when managing systems-savvy selling processes. By sampling within an industry in which the research team benefits from significant expertise, the constructivist grounded theory approach relying on semistructured, in-depth interviews used herein leverages the research team’s expertise while controlling for industry-level effects. 相似文献

The experiences people have over the course of their careers are commonly held to contribute to creative achievement. In this study, an attempt was made to identify the career events contributing to creative achievement in the sciences. Prior theoretical and empirical work was used to identify relevant career events in the areas of education, domain exposure, mentoring, adversity, work procedures, collaboration, laboratory leadership, and organizational influences. Obituaries were obtained for 499 scientists working in multiple fields in the social, physical, life, and health sciences and were used to assess whether these events were evident in scientists' careers. Comparisons of high achieving and low achieving scientists with regard to these events indicated that multiple events lying in each of these general areas contributed to career achievement. The nature of the events yielding significant differences were discussed regarding their implications for the development of creative potential in scientific fields. 相似文献

Scholars have proposed a number of courses and programs intended to improve the ethical behavior of scientists in an attempt to maintain the integrity of the scientific enterprise. In the present study, we conducted a quantitative meta-analysis based on 26 previous ethics program evaluation efforts, and the results showed that the overall effectiveness of ethics instruction was modest. The effects of ethics instruction, however, were related to a number of instructional program factors, such as course content and delivery methods, in addition to factors of the evaluation study itself, such as the field of investigator and criterion measure utilized. An examination of the characteristics contributing to the relative effectiveness of instructional programs revealed that more successful programs were conducted as seminars separate from the standard curricula rather than being embedded in existing courses. Furthermore, more successful programs were case based and interactive, and they allowed participants to learn and practice the application of real-world ethical decision-making skills. The implications of these findings for future course development and evaluation are discussed. 相似文献

Abstract Obsessive-compulsive disorder (OCD) is a debilitating psychiatric condition with a heterogeneous array of obsessions and compulsions. Although factor analytic studies have identified symptom dimensions comprising the clinical presentation of OCD, many frequently reported miscellaneous symptoms are not considered in factor analytic studies because they do not fit conceptually within a particular symptom category, despite being functionally related. In the present study, we examined the associations between miscellaneous symptoms and OCD symptom dimensions in a sample of 111 adults with OCD. Overall, most miscellaneous symptoms were associated with one or more symptom dimensions in previously identified four- (14 of the 22 symptoms) and five-factor models (12 of the 22 symptoms). In both models, Contamination/Cleaning was the only dimension not related to any miscellaneous symptom. The present results provide information about which miscellaneous symptoms may be related to particular symptom dimensions, which will assist in clinical evaluations and help planning behavioral psychotherapy (e.g., hierarchy development). 相似文献

Community dwelling military families from the National Guard and Reserve contend with deployment-related stressors in relative isolation, living in communities where mental health providers may have little knowledge of military culture. When they are community residents, active duty service members and families tend to live in close proximity to their military installations. This article will focus primarily on the challenges to quality mental health care for reserve component (RC) families. Where studies of RC families are absent, those of active component (AC) families will be highlighted as relevant. Upon completion of a deployment, reintegration for RC families is complicated by high rates of symptomatology, low service utilization, and greater barriers to care relative to AC families. A paucity of providers skilled in evidence-based treatments (EBTs) limits community mental health capacity to serve RC military families. Several emergent programs illustrate the potential for better serving community dwelling military families. Approaches include behavioral health homes, EBTs and treatment components, structured resiliency and parent training, military informed schools, outreach methods, and technology-based coping, and psychoeducation. Methods from implementation science to improve clinical skill acquisition and spread and sustainability of EBTs may advance access to and quality of mental health treatment and are reviewed herein. Recommendations related to research methods, military knowledge and treatment competencies, and transition to a public health model of service delivery are discussed. 相似文献

Five experiments investigated how people use categories to make inductions about objects whose categorisation is uncertain. Normatively, they should consider all the categories the object might be in and use a weighted combination of information from all the categories: bet-hedging. The experiments presented people with simple, artificial categories and asked them to make an induction about a new object that was most likely in one category but possibly in another. The results showed that the majority of people focused on the most likely category in making inductions, although there was a group of consistently normative responders who used information from both categories (about 25% of our college population). Across experiments the overall pattern of results suggests that performance in the task is improved not by understanding the underlying principles of bet-hedging but by increasing the likelihood that multiple categories are in working memory at the time of the induction. We discuss implications for improving everyday inductions. 相似文献

We studied the ability of pigs to discriminate tone cues using successive and conditional discrimination tasks. Pigs (n = 8) were trained in a successive discrimination Go/No-Go task (Experiment 1) to associate a Go-cue with a reward at the end of a runway and a No-Go-cue with the absence of reward. Latency to reach the goal-box was recorded for each cue-type. Learning of a conditional discrimination task was compared between low-birthweight (LBW, n = 5) and normal-birthweight (NBW, n = 6) pigs (Experiment 2) and between conventional farm (n = 7) and Göttingen miniature (n = 8) pigs (Experiment 3). In this active-choice task, one cue signalled a response in a right goal-box was correct and a second cue signalled a response in a left goal-box was correct. Cues were differentially rewarded. The number of sessions to learn the discrimination and number of correct choices per cue-type were recorded. In Experiment 1, four out of eight pigs showed learning on the task, that is, a higher latency to respond to the No-Go-cue, within 25 sessions. In Experiment 2, eight out of 11 pigs learned the discrimination within 46 sessions. LBW learners learned faster than NBW learners. In Experiment 3, all 15 pigs learned the task within 16 sessions. Göttingen miniature pigs learned faster than conventional farm pigs. While some methodological issues may improve the Go/No-Go design, it is suggested that an active-choice task yields clearer and more consistent results than one relying on latency alone. 相似文献

Lakshminarayanan et al. (J Exp Soc Psychol 47: 689–693, 2011) showed that when choice is between variable (risky) and fixed (safe) food amounts with the same expected values, capuchins prefer the safe alternative if choice is framed as a gain, but the risky alternative if it is framed as a loss. These results seem similar to those seen in human prospect-theory tests in choice between variable and fixed gains or losses. Based on this similarity, they interpreted their results as identifying a between-species commonality in cognitive function. In this report, we repeat their experiment with humans as subjects (an up-linkage replication). Whether choices were rewarded with candy or nickels, choice approximated indifference whether framed as gains or losses. Our data mirror those of others who found that when humans make risky choices within a repeated-trials procedure without verbal instruction about outcome likelihoods, preference biases seen in one-shot, language-guided, prospect-theory tests such as Tversky and Kahneman’s (Science 211:453–458, 1981) reflection effect may not appear. The disparity between our findings and those of Lakshminarayanan et al. suggests their study does not evidence a cognitive process shared by humans and capuchins. 相似文献

The International Classification of Diseases has recently defined Prolonged Grief Disorder (PGD) with symptoms such as longing, worry, and intense emotional pain that exceed sociocultural norms more than 6 months after the loss. This study aims to (a) estimate the prevalence of this new diagnostic category, (b) identify its sociodemographic and loss-related predictors, and (c) assess the co-occurrence of PGD with other psychological disorders and substance abuse. A large representative sample of Spanish adults (N = 1498) participated. Several multivariate binary logistic regression and multivariate logistic regression models were used. Results showed a 9.95% prevalence in the total sample. Catholic beliefs were a positive predictor, while higher income and more time since loss significantly decreased the odds of PGD. PGD significantly increased the likelihood of anxiety, depression, somatisation, post-traumatic stress disorder, loneliness and substance use. Our study contributes to assessing the multicultural PGD validity, as our results from a large representative sample are comparable to those in other countries with the PGDS. Our findings have direct implications for the assessment and treatment of bereavement, identifying for practitioners variables that make individuals more vulnerable to PGD. Results highlighted the high co-occurrence of PGD with other psychological illnesses and increased drug use. 相似文献
