Adventure participants have traditionally been viewed as having thrill or risk-seeking motives, and this perception remains despite empirical research suggesting that other motives may drive participation. This study was conducted to extend understanding of participation motives of adventure recreation participants in relation to Csiksentmihalyi’s nine-dimension model of flow and other proposed motivational constructs. Participants (n = 199) who had typically engaged in their adventure recreation activity (i.e., highlining, rock climbing, downhill mountain biking, freefalling, snow sports) regularly, and with considerable competence, took part in this investigation by completing self-report measures of dispositional flow (The Dispositional Flow Scale; DFS-2), state flow (The Short Flow State Scale; SFSS), and participation motives in their adventure recreation environments. Support was observed in confirmatory factor analytic procedures for the factorial validity of DFS-2 and SFSS data obtained from adventure recreation participants. Mean scores from measures on participant experience of flow in adventure recreation were generally found to be significantly higher than previously observed in other physical activity domains, with some differences also being observed among adventure recreation subgroups. Contrary to traditional explanations of adventure recreation participation, risk-seeking was not supported as a key underlying motive by participants in this study. Mastery of one’s adventure recreation activity, perceived connection to one’s activity, and trust in one’s skills, were identified as important participation motives. This study demonstrated that the DFS-2 and SFSS were able to satisfactorily assess flow constructs in adventure recreation, and supported recent research demonstrating flow to be a relevant experience to this setting. The implications of these findings for theory, practice, and future research directions in adventure recreation are discussed.  相似文献

Objective

This qualitative study investigated therapist training experiences, elements of skill acquisition, and barriers and facilitators associated with conducting assessments, and the delivery of low- and high-intensity therapist assistance delivered via video chat technology, adjunctive to a transdiagnostic digital mental health intervention programme for anxiety and depression.

Methodology

In total, 34 semistructured interviews were conducted with 20 therapists. Twenty interviews explored experiences of training to administer a clinical assessment tool, and 14 additional interviews explored training experiences of delivering low- and high-intensity therapist assistance via video chat technology.

Results

Reflexive thematic analysis identified three themes: video chat skill acquisition, competencies transferrable to video chat and video chat service quality. Training and supervision were identified as important to scaffold skill development, and therapists described surprise that their skill set was transferrable to video chat. The most cited barrier to the adoption of video chat was the management of risk and distress, along with environmental suitability. Frequently cited facilitators to the adoption of video chat included stable Internet connection, protocols and resources.

Conclusion

The benefits of video chat technology and digital mental health interventions can be maximised through the expansion and integration of training into existing teaching curricula. If therapists are familiarised and competent to deliver mental health services via the Internet, as well as in person, the future adoption of blended and stepped-care models is likely to be increased.  相似文献

The global COVID-19 pandemic led to a widespread increase in remote work arrangements. This trend raised concerns regarding the potential negative ramifications it might have for organizational trust and cooperation. We explored the initial effect of COVID-19 induced remote work on trust in organizations: trust in co-workers, trust in the supervisor and in the organization at large. In a four-wave longitudinal survey of remote workers (N ∼ 1000) in the UK conducted between May 2020 and August 2020 (first COVID wave), we examined the association between the share of remote work (out of total working hours) and different forms of trust at work. The results showed that, for the same individual, increasing the share of working hours spent remotely was associated with more trust in the organization at large (but not in the supervisor and co-workers). Further, during the months where individuals spent more time working remotely, they experienced lower turnover intentions (but not less burnout or more work engagement, productivity, and satisfaction) compared to the months where they spent less time working remotely. The results contribute to the literature on flexible work arrangements, organizational trust, and other work outcomes.  相似文献

This study examined the relationship of contextual factors to organizational commitment among 372 police officers in 13 police commands in New York City's public housing projects. Setting-level variables were formed by aggregating officers' perceptions of management support and fairness and management sensitivity to diversity within commands and within three subgroups formed by gender and ethnicity. Individual-level measures were deviations from these subgroup means within commands as well as perceptions of support from family and social support and negative interactions within commands. Overall, path analyses, confirmed by hierarchical linear modeling, showed direct setting-level effects for management support and fairness, but not for sensitivity to diversity, on organizational commitment. Both women and minority men experienced more negative social interactions than white men; support from management, co-workers, and family were important predictors of commitment. Family support was particularly important for women.  相似文献

Reinforcing effects of caffeine in coffee and capsules.   总被引:3,自引:0,他引:3  
In a residential research ward the reinforcing and subjective effects of caffeine were studied under double-blind conditions in volunteer subjects with histories of heavy coffee drinking. In Experiment 1, 6 subjects had 13 opportunities each day to self-administer either a caffeine (100 mg) or a placebo capsule for periods of 14 to 61 days. All subjects developed a clear preference for caffeine, with intake of caffeine becoming relatively stable after preference had been attained. Preference for caffeine was demonstrated whether or not preference testing was preceded by a period of 10 to 37 days of caffeine abstinence, suggesting that a recent history of heavy caffeine intake (tolerance/dependence) was not a necessary condition for caffeine to function as a reinforcer. In Experiment 2, 6 subjects had 10 opportunities each day to self-administer a cup of coffee or (on different days) a capsule, dependent upon completing a work requirement that progressively increased and then decreased over days. Each day, one of four conditions was studied: caffeinated coffee (100 mg/cup), decaffeinated coffee, caffeine capsules (100 mg/capsule), or placebo capsules. Caffeinated coffee maintained the most self-administration, significantly higher than decaffeinated coffee and placebo capsules but not different from caffeine capsules. Both decaffeinated coffee and caffeine capsules were significantly higher than placebo capsules but not different from each other. In both experiments, subject ratings of "linking" of coffee or capsules covaried with the self-administration measures. These experiments provide the clearest demonstrations to date of the reinforcing effects of caffeine in capsules and in coffee.  相似文献

Limited information exists on the relationship between sexual violence victimization and health among African American women. Using data from a community sample of African American women, we examine the association between current health and lifetime experiences of sexual violence. In-person interviews were completed in 2010. Among interviewees, 53.7% of women reported rape victimization and 44.8% reported sexual coercion in their lifetime. Victims of rape or sexual coercion were significantly more likely to report depression and posttraumatic stress disorder during their lifetime. Among victims whose first unwanted sexual experience was rape or sexual coercion, perpetrators were mostly acquaintances and intimate partners, and over one third were injured and needed services. More attention is needed on the health needs of African American women and their association to victimization status.  相似文献

Although the personality–performance relationship has been studied extensively, most studies focused on the relationship between between-person differences in the Big Five personality dimensions and between-person differences in job performance. The current paper extends this research in two ways. First, we build on core self-evaluations (CSEs): an alternative, broad personality dimension that has proven to be a good predictor of job performance. Second, we tested concurrent and lagged within-person relationships between CSEs and task performance, organizational citizenship behaviour (OCB), and counterproductive work behaviour (CWB). To this end, we conducted two experience sampling studies; the first one assessing the relationship between state CSEs and levels of momentary task performance and OCB, and a second study in which employees reported on their level of state CSEs and momentary CWB. Results showed that there is substantial within-person variability in CSEs and that these within-person fluctuations relate to within-person variation in task performance, OCB, and CWB towards the organization, and CWB towards the individual. Moreover, CSEs prospectively predicted within-person differences in task performance and CWB towards the organization, whereas the reversed effect did not hold. These findings tentatively suggest that state CSEs predict performance, rather than the other way around.  相似文献

In today’s quickly changing work environment, many individuals want to be creative at their workplace, but only some of them succeed at manifesting these tendencies. In three studies, using both field and experimental data, we focused on transforming individuals’ preference for creativity, defined as an inclination for liking and wanting to be creative, into actual creativity. We first conducted a pilot Study 1 to establish discriminant validity to related constructs and provided initial evidence on predictive and incremental validity of the preference-for-creativity scale. Next, we performed a field Study 2, where we found that transforming preferences for creativity into supervisor-rated creativity is contingent upon employees’ perceptions of clear outcome goals. Clear outcome goals fostered individuals’ preference for creativity to result in higher levels of supervisor-rated creative behaviour—a finding that was replicated in an experimental Study 3. Furthermore, we explored whether work enjoyment mediated the moderated relationship between preference for creativity and creative outcomes. The results supported our mediated moderation model, whereby the manipulation of clear goals led to higher work enjoyment, influencing individuals’ preference for creativity to result in higher ratings of their creative outcomes.  相似文献
