Leadership, collective personality, and performance   总被引:1,自引:0,他引:1  
By viewing behavior regularities at the individual and collective level as functionally isomorphic, a referent-shift compositional model for the Big 5 personality dimensions is developed. On the basis of this compositional model, a common measure of Big 5 personality at the individual level is applied to the collective as a whole. Within this framework, it is also hypothesized that leadership (i.e., transformational, transactional, and passive) would predict collective personality and that collective personality would be significantly related to collective performance. The results supported these hypotheses using a sample of franchised units. On the basis of recent research at the individual level, several interactions among the various personality dimensions were hypothesized and supported. Implications are discussed.  相似文献

Theoretical models of social phobia propose that biased attention contributes to the maintenance of symptoms; however these theoretical models make opposing predictions. Specifically, whereas Rapee and Heimberg (1997) suggested the biases are characterised by hypervigilance to threat cues and difficulty disengaging attention from threat, Clark and Wells (1995) suggested that threat cues are largely avoided. Previous research has been limited by the almost exclusive reliance on behavioural response times to experimental tasks to provide an index of attentional biases. The current study evaluated the relationship between the time-course of attention and symptoms of social anxiety and depression. Forty-two young adults completed a dot-probe task with emotional faces while eye-movement data were collected. The results revealed that increased social anxiety was associated with attention to emotional (rather than neutral) faces over time as well as difficulty disengaging attention from angry expressions; some evidence was found for a relationship between heightened depressive symptoms and increased attention to fear faces.  相似文献

Implementation experts suggest tailoring strategies to the intended context may enhance outcomes. However, it remains unclear which strategies are best suited to address specific barriers to implementation, in part because few measurement methods exist that adhere to recommendations for reporting. In the context of a dynamic cluster randomized trial comparing a standardized to tailored approach to implementing measurement-based care (MBC), this study aimed to (a) describe a method for tracking implementation strategies, (b) demonstrate the method by tracking strategies generated by teams tasked with implementing MBC at their clinics in the tailored condition, and (c) conduct preliminary examinations of the relation between strategy use and implementation outcomes (i.e., self-reported fidelity to MBC). The method consisted of a coding form based on Proctor, Powell, and McMillen (2013) implementation strategy reporting guidelines and Powell et al.’s (2012) taxonomy to facilitate specification of the strategies. A trained research specialist coded digitally recorded implementation team meetings. The method allowed for the following characterization of strategy use. Each site generated 39 unique strategies across an average of six meetings in five months. There was little variability in the use of types of implementation strategies across sites with the following order of prevalence: quality management (50.00%), restructuring (16.53%), communication (15.68%), education (8.90%), planning (7.20%), and financing (1.69%). We identified a new category of strategies not captured by the existing taxonomy, labeled “communication.” There was no evidence that number of implementation strategies enacted was statistically significantly associated with changes in self-reported fidelity to MBC—however, financing strategies were associated with increased fidelity. This method has the capacity to yield rich data that will inform investigations into tailored implementation approaches.  相似文献

Situation selection involves choosing situations based on their likely emotional impact and may be less cognitively taxing or challenging to implement compared to other strategies for regulating emotion, which require people to regulate their emotions “in the moment”; we thus predicted that individuals who chronically experience intense emotions or who are not particularly competent at employing other emotion regulation strategies would be especially likely to benefit from situation selection. Consistent with this idea, we found that the use of situation selection interacted with individual differences in emotional reactivity and competence at emotion regulation to predict emotional outcomes in both a correlational (Study 1; N?=?301) and an experimental field study (Study 2; N?=?125). Taken together, the findings suggest that situation selection is an effective strategy for regulating emotions, especially for individuals who otherwise struggle to do so.  相似文献

Neurocognitive problems in childhood survivors of brain tumors are well documented. Further, research has shown that problems in cognitive functioning may be associated with impairment in the use of complex strategies needed to cope with stress, including secondary control coping strategies (e.g., acceptance and cognitive reappraisal) which have been associated with fewer adjustment problems. The present study measured cognitive function, coping strategies, and adjustment in children ages 6–16 years at the time of brain tumor diagnosis and at two follow-up time-points up to 1 year post-diagnosis. In a prospective design, working memory was assessed in a total of 29 pediatric brain tumor patients prior to undergoing surgery, child self-reported coping was assessed at 6 months post-diagnosis, and parent-reported child adjustment was assessed at 12 months post-diagnosis. Significant correlations were found between working memory difficulties and secondary control coping. Secondary control coping was also negatively correlated with child attention and total problems. Regression analyses did not support secondary control coping mediating the association between working memory difficulties and child attention or total problems. These findings represent the first longitudinal assessment of the association between working memory, coping, and adjustment across the first year of a child’s brain tumor diagnosis and suggest a possible role for early interventions addressing both working memory difficulties and coping in children with brain tumors.  相似文献

Youth involved in the juvenile justice system are at risk for emotional and behavioral problems. However, research with court-involved adolescents has neglected to examine the mental health of their parents, who may also have significant personal and parenting stress. This sample consisted of 144 parent–adolescent dyads. Adolescents (aged 11–17 years) identified by court officials were referred to the study to receive mental health treatment. Parents and adolescents completed surveys about their mental health diagnoses, treatment, and family relationships. Using the clinical cut-off for the global severity index of the Symptom Checklist-90-Revised, bivariate and multiple logistic regression analyses were performed to examine group differences between parents with and without significant mental health symptoms. Results indicated that 35% of parents endorsed clinically significant mental health symptoms. Parents with clinically significant symptoms, compared to those without, reported significantly greater parenting stress (p?<?.05), and were more likely to have received prior mental health treatment (54 vs. 25%; p?<?.05) and a psychiatric diagnosis (52 vs. 19%; p?<?.05). Our findings revealed that more than one in three parents of court-involved adolescents are currently experiencing significant mental health symptoms. Improved mental health screening and intervention that incorporates the unique needs of families is recommended, including the possible use of family-based approaches as well as individualized treatment for the parents of court-involved youth.  相似文献

Since its inception in 2001, the best possible selves (BPS) activity has been the focus of more than 30 studies which have shown it to be a viable intervention for increasing optimism, positive affect, health and well-being. It is timely to critically review the findings from the BPS literature and suggest directions for future research. The majority of BPS studies have used an experimental methodology and have administered the BPS activity to diverse groups including students, adults, depressive individuals and suicidal inpatients. The BPS intervention can be effective when administered in-person or on-line and repeating the activity appears to enhance efficacy. Suggestions for future research include: (a) investigation of mediator variables, (b) additional outcome variables such as hope and appreciation, (c) comparative studies regarding dosage to enhance effectiveness, (d) extension of the BPS into a best-possible-other activity, (e) diversity of delivery methods, and (f) thematic content analysis of BPS text.  相似文献

Past research suggests that individuals high in basal testosterone are motivated to gain high status. The present research extends previous work by examining endocrinological and behavioral consequences of high and low status as a function of basal testosterone. The outcome of a competition--victory versus defeat--was used as a marker of status. In Study 1, high testosterone men who lost in a dog agility competition rose in cortisol, whereas high testosterone men who won dropped in cortisol. Low testosterone men's cortisol changes did not depend on whether they had won or lost. Study 2 replicated this pattern of cortisol changes in women who participated in an experimental laboratory competition, and Study 2 extended the cortisol findings to behavior. Specifically, high testosterone winners chose to repeat the competitive task, whereas high testosterone losers chose to avoid it. In contrast, low testosterone winners and losers did not differ in their task preferences. These results provide novel evidence in humans that basal testosterone predicts cortisol reactivity and behavior following changes in social status. Implications for the social endocrinology of dominance are discussed.  相似文献

African American youth are less likely to use alcohol than their European American counterparts; however, the greater consequences of use for African American youth highlight the need for greater research attention to this group. Two social contexts that have been linked with adolescent alcohol use are parents and peers, yet these studies have rarely included African American youth or failed to examine potential racial differences. This study examined the main and interactive effects of parents and peers, as well as the moderating role of race on alcohol use, in African American and European American rural adolescents (n=71) identified as at high-risk for alcohol use. Contrary to study hypotheses, however, parents were not a more robust moderator for African American than European American youth. Clinical implications for prevention and intervention programming for both African American and European American youth are discussed.  相似文献

The mere-exposure literature has shown that familiar objects are preferred to novel objects. However, no work has definitively shown that mere exposure can direct and facilitate approach movements. In Experiment 1, participants were shown stimuli and were later re-exposed to them along with novel stimuli. Participants were directed to make an approach or avoidant motion to each and response times were recorded. As predicted, participants were quicker to approach and slower to avoid familiar relative to novel stimuli. In Experiment 2, participants were shown mere-exposed and novel symbols and were asked to “push” or “pull” a joystick in response to each, based on their intuition. Extending Experiment 1’s findings, participants freely selected an approach response more frequently for familiar compared to novel stimuli. Moreover, in this same experiment, familiar stimuli were judged as more likeable than were novel stimuli, and participants’ liking for familiar stimuli correlated with the frequency with which they were approached. Implications of these findings are discussed.  相似文献
