Research has shown that self‐efficacy is often one of the most important personal resources in the work context. However, because this research has focused on cognitive and task‐oriented self‐efficacy, little is known about social and emotional dimensions of self‐efficacy at work. The main aim of the present study was to investigate social and emotional self‐efficacy dimensions at work and to compare them to a cognitive and task‐oriented dimension. Scales to measure social and emotional self‐efficacy at work were developed and validated and found to be well differentiated from the cognitive task‐oriented occupational self‐efficacy scale. Confirmatory factor analyses of data from 226 Swedish and 591 German employees resulted in four separate but correlated self‐efficacy dimensions: (1) occupational; (2) social; (3) self‐oriented emotional; and (4) other‐oriented emotional. Social self‐efficacy explained additional variance in team climate and emotional self‐efficacy in emotional irritation and emotional exhaustion, over and above effects of occupational self‐efficacy. Men reported higher occupational self‐efficacy, whereas social and emotional self‐efficacy revealed no clear gender differences. The scales have strong psychometric properties in both Swedish and German language versions. The positive association between social self‐efficacy and team climate, and the negative relationships between self‐oriented emotional self‐efficacy and emotional irritation and emotional exhaustion may provide promising tools for practical applications in work settings such as team‐building, staff development, recruitment or other training programs aiming for work place health promotion. The next step will be to study how social and emotional self‐efficacy relate to leadership, well‐being and health over time.  相似文献

This study examined the relationship between traditional masculine role norms (status, toughness, anti‐femininity) and psychosocial mechanisms of sexual risk (sexual communication, sexual self‐efficacy) among young, low‐income, and minority parenting couples. Between 2007 and 2011, 296 pregnant adolescent females and their male partners were recruited from urban obstetrics clinics in Connecticut. Data regarding participants' beliefs in masculine role norms, frequency of general sex communication and sexual risk communication, and sexual self‐efficacy were collected via computer‐assisted self‐interviews. Generalized estimating equation (GEE) models were used to test for actor effects (whether a person's masculine role norms at baseline influence the person's own psychosocial variables at 6‐month follow‐up) and partner effects (whether a partner's masculine role norms at baseline influence an actor's psychosocial variables at 6‐month follow‐up). Results revealed that higher actor status norms were significantly associated with more sexual self‐efficacy, higher actor toughness norms were associated with less sexual self‐efficacy, and higher actor anti‐femininity norms were significantly associated with less general sex communication, sexual risk communication, and sexual self‐efficacy. No partner effects were found. These results indicate a need for redefining masculine role norms through family centered approaches in pregnant or parenting adolescent couples to increase sexual communication and sexual self‐efficacy. Further research is needed to understand partner effects in the context of a relationship and on subsequent sexual risk behavior.  相似文献

The authors explored the effects of a structured‐group career intervention among 280 Italian high school students. Hierarchical linear models indicated the intervention's effectiveness in increasing career decision‐making self‐efficacy and, consequently, career exploration, but not in decreasing career choice anxiety. In addition, partial confirmation was found for the moderating effects of participants' expectations and motivation to change on the relationship between career decision‐making self‐efficacy and career choice anxiety. The findings support the development of a systematic vocational guidance program in Italian schools.  相似文献

This paper argues for hands-on, contextual and problem-solving collaborations, that is, for a transdisciplinary approach that establishes direct connections between social and technical disciplines. It is based on our experience as a team of researchers at the Vitruvius Fab Lab (Digital Fabrication Laboratory) of ISCTE-IUL (University Institute of Lisbon, Portugal). The paper presents a particular research and learning initiative–STTF2013 Summer School ‘Sustainable Technologies and Transdisciplinary Futures: From Collaborative Design to Digital Fabrication’, which served as a testbed for our transdisciplinary, critical and open approach. We address its rationale and main challenges, while also discussing recommendations for other transdisciplinary projects striving to integrate social and technical disciplines in research and innovation.  相似文献

Co-rumination is associated with positive friendship quality (thought to buffer against anxiety and depression) but paradoxically higher levels of anxiety and depression. With the increasing use of technology for communication among adults, there is little known about co-rumination effects across different modalities of communication. In the current study, we examined co-rumination through four methods (i.e. in person, phone calls, text messaging, and social media) in two separate samples - college students and participants from the community. Classic co-rumination effects were found for in-person communications, and we found that co-rumination by telephone as well as by texting, for a college student sample only, mirrors some of these findings for in-person co-rumination. In studies of co-rumination, evaluation of multiple modes of communication is warranted.  相似文献

This study investigated the relationship of family environment, network, parental socio‐economic status, self‐efficacy and proactive personality on entrepreneurial intention of secondary school adolescents and the mediating role of self‐efficacy. The participants were 250 secondary school SS2 adolescents randomly selected from six secondary schools in Ibadan Metropolis, Ibadan, Oyo State, Nigeria. Structural Equation Modelling was used to analyse the data obtained from the participants. The results showed that all the contextual and individual factors had significant relationship with entrepreneurial intention and self‐efficacy partially mediated the relationship. It was suggested that counselling psychologists should consider the contextual and individual variables while assisting students in building their entrepreneurial intention.  相似文献

Intrigued by relationship between team motivational context and individual characteristics in the organizational reality, we developed and tested a cross‐level model to investigate the interactive effects of team empowerment and individual goal orientations on individual creative performance through the mediating mechanism of an individual's creative self‐efficacy. Using multi‐wave multi‐source data from 63 R&D teams in three IT companies, we found that (1) team empowerment, individual learning goal orientation, and individual performance orientation are all positively related to individual creative performance through mediation of creative self‐efficacy; (2) learning orientation and performance approach orientation could both supplement the effects of team empowerment on individual creative self‐efficacy. Our findings point to the importance of individual goal orientation in shaping the effects of team motivation climates and provide insights for both scholars and practitioners. The specific practical implications include but are not limited to (1) individuals with learning and performance approach orientations should be identified during hiring procedures given that they could still thrive in less empowered teams and maintain a relatively high level of creative self‐efficacy and creative outcomes; (2) managers should consider assigning employees who are more learning oriented to more empowering and open‐ended tasks in order to obtain better creative results.  相似文献

Contingency management (CM) interventions are among the most effective behavioral interventions for smoking. This study assessed the effects of CM and electronic cigarettes (ECs) on smoking reductions and abstinence for durations of 30‐36 days. Twelve participants were exposed to Baseline, EC alone, and EC + CM conditions. An internet‐based platform was used to monitor smoking via breath carbon monoxide (CO) and deliver CM for smoking abstinence (CO ≤4 ppm). A Bluetooth‐enabled EC monitored daily EC puffs. Abstinence rates were equivalent between EC (34.4%) and EC + CM (30.4%) conditions. Both conditions promoted smoking reductions. We observed an inverse correlation between smoking and EC puffs (r = ‐.62, p < .05). Results suggest the use of electronic cigarettes can promote smoking reductions and abstinence, and CM did not improve these outcomes. Larger magnitude consequences or tailoring EC characteristics (e.g., flavor) may have improved outcomes. Technology‐based methods to collect intensive, longitudinal measures of smoking and electronic cigarette use may be useful to characterize their environmental determinants.  相似文献

On average, veterans are more civically and politically engaged than civilians. Previous research on the effects of military service, however, did not account for differences in veterans’ combat experiences. Using survey data from a representative sample of Vietnam veterans, this study presents evidence that veterans who were exposed to severe combat trauma and veterans who exhibited attitudes and fears associated with post‐traumatic stress had significantly lower levels of political efficacy and trust. The negative consequences of combat exposure and post‐traumatic stress are not mitigated when veterans have quality social support or when they seek professional counseling. These findings inform political psychology and hold implications for claims regarding the empowering influence of service in the U.S. military, increased political engagement, in particular. Among Vietnam veterans, exposure to severe combat trauma and post‐traumatic stress were both associated with reduced political efficacy and trust.  相似文献
