The work of volunteers is indispensable for the well functioning of healthcare organizations, and for maintaining the quality of care in times of austerity. As feelings of intrinsic motivation stimulate volunteer well-being and their long-term engagement, we study how team inclusion relates to volunteers’ intrinsic motivation during their activities. We hypothesize that volunteers’ perceptions of inclusion are positively related to intrinsic motivation, via the satisfaction of their basic needs for autonomy, competence, and relatedness. To test our hypothesis, we conducted a daily-diary study, obtaining a final sample of 43 volunteers and 204 completed diaries. Multilevel path analyses showed that team inclusion was positively related to volunteers’ intrinsic motivation during their activities. Subsequent mediation analyses revealed that competence and relatedness need satisfaction mediated this relationship. Thus, when volunteers feel part of the team with which they complete their activities, they experience intrinsic motivation because feeling included stimulates their feelings of being competent and being related to others.  相似文献

The quality of working life under the production system known as lean manufacturing (LM) is a heavily debated topic. Little is known about the engagement level of employees under this system. Our study is concerned with how employees in this context craft their jobs to enhance their own engagement, and we specifically consider how daily skill utilization triggers this process. Using a cross-level perspective, we further consider whether job-level characteristics relevant to the lean context, namely task interdependence and boundary control, restrict or facilitate the effects of daily skill utilization. A daily diary study was conducted over 4 working days with 64 employees in a large company utilizing LM. The results of multilevel structural equation modelling demonstrated that on a given day, skill utilization was associated with seeking resources, and this relationship was stronger when employees had high boundary control and low task interdependence in their general job roles. Results further demonstrated that employees experienced higher work engagement on days when they sought resources and challenges. Our findings illustrate the motivational potential of job crafting under LM and how crafting activities can be facilitated by the design of jobs and allocation of daily tasks.  相似文献

This study investigates the daily relationship between experiencing home–work conflict (HWC) and an employee’s performance of counterproductive work behaviour (CWB) directed towards the individual (CWBI) and CWB directed towards the organization (CWBO). Moreover, we examine whether these relationships are buffered by family supportive supervisor behaviour. Finally, we investigate whether CWBs directed towards the individual and the organization are related to feelings of work–home conflict (WHC). We examined the daily diary data using multilevel path analyses. We found support for a significant positive relation between HWC and same as well as next-day CWB enacted towards the individual, and same-day CWB directed towards the organization. General levels of family supportive supervisor behaviour buffered an employee’s daily relationship between experiencing HWC and enacting counterproductive work behaviour towards the individual, and are directly and negatively related with enacting CWB towards the individual and the organization. Furthermore, daily CWB enacted towards the individual was significantly positive, whereas CWB enacted towards the organization was significantly negatively related to WHC. Future research would benefit from examining buffering effects on the resource-depleting relationship between counterproductive work behaviour enacted towards the individual and WHC.  相似文献

Understanding the relationship between memory function and lifestyle offers great opportunities for promoting beneficial lifestyle choices to foster healthy cognitive aging and for the development of intervention programs for older adults. We studied a cohort of older adults (age 65 and older) enrolled in the Longitudinal Aging Study Amsterdam, an ongoing prospective population-based research project. A total of 1,966 men and women participated in an episodic memory test every 3 years over a period of 14 years. Lifestyle habits were repeatedly assessed using self-report measures. Physical activity, light-to-moderate alcohol consumption, difficulties staying asleep, and social engagement were associated with better memory function over the course of 14 years. In contrast, smoking and long sleep duration were associated with worse memory function. These findings suggest that certain lifestyle factors can have long-term protective or harmful effects on memory function in aging individuals.  相似文献

The aim of the current vignette study is to map the style, type, and themes of questions that are asked when assessing the credibility of asylum seekers' claims. Sixty‐five officials from the Swedish Migration Agency (Migrationsverket ), were asked to respond to one out of four different vignettes that contained fictitious asylum narratives. Each vignette presented the types of problems often encountered by officials at the migration board. Two of the vignettes contained no evidence of the origin of the asylum seeker. The other two contained no evidence for the claim of persecution. The asylum officials were asked to formulate five questions that would help them to assess the veracity of the applicant's claim. Our analyses showed that they mainly formulated open questions in an information gathering style. A thematic analysis of the questions revealed that when a claim about origin was assessed, asylum officials mostly asked questions about life in the country of origin, identity documents, and the flight to Europe. When the claim about persecution was assessed, in contrast, asylum officials mostly formulated case‐specific questions (e.g., how the applicant was arrested). Hence, when the credibility of claims about origin is assessed, there seems to be a typical set of questions that asylum officials use. The asylum officials seem to assume that if the applicant is truly originating from a specific country or area, he or she should have ample knowledge about that area, its customs, and frequently encountered objects.  相似文献

Procrastination is a common self-regulatory failure that can have a negative impact on well-being and performance. However, few clinical trials have been conducted, and no follow-up has ever been performed. The current study therefore aimed to provide evidence for the long-term benefits and investigate predictors of a positive treatment outcome among patients receiving Internet-based cognitive behavior therapy (ICBT). A total of 150 self-recruited participants were randomized to guided or unguided ICBT. Self-report measures of procrastination, depression, anxiety, and quality of life were distributed at pre-treatment assessment, post-treatment assessment, and one-year follow-up. Mixed effects models were used to investigate the long-term gains, and multiple linear regression for predictors of a positive treatment outcome, using the change score on the Irrational Procrastination Scale as the dependent variable. Intention-to-treat was implemented for all statistical analyses. Large within-group effect sizes for guided and unguided ICBT, Cohen’s d = .97–1.64, were found for self-report measures of procrastination, together with d = .56–.66 for depression and anxiety. Gains were maintained, and, in some cases, improved at follow-up. Guided and unguided ICBT did not differ from each other, mean differences ?.31–1.17, 95% CIs [?2.59–3.22], and none of the predictors were associated with a better result, bs ?1.45–1.61, 95% CIs [?3.14–4.26]. In sum, ICBT could be useful and beneficial in relation to managing procrastination, yielding great benefits up to one year after the treatment period has ended, with comparable results between guided and unguided ICBT.  相似文献

Executive function is a broad construct that encompasses various processes involved in goal‐directed behaviour in non‐routine situations (Banich, 2009). The present study uses a sample of 560 5‐ to 16‐year‐old twin pairs (M = 11.14, SD = 2.53): 219 monozygotic twin pairs (114 female; 105 male) and 341 dizygotic twin pairs (136 female, 107 male; 98 opposite sex) to extend prior literature by providing information about the factor structure and the genetic and environmental architecture of the Behavior Rating Inventory of Executive Function (BRIEF; Gioia et al., 2000, Child Neuropsychol., 6, 235; Gioia et al., 2000, Behavior rating inventory of executive function, Lutz, FL: Psychological Assessment Resources), a multifaceted rating scale of everyday executive functions. Phenotypic results revealed a 9‐scale, 3‐factor model best represents the BRIEF structure within the current sample. Results of the genetically sensitive analyses indicated the presence of rater bias/contrast effects for the Initiate, Working Memory, and Task‐Monitor scales. Additive genetic and non‐shared environmental influences were present for the Initiate, Plan/Organize, Organization of Materials, Shift, and Monitor and Self‐Monitor scales. Influences on Emotional Control were solely environmental. Interestingly, the aetiological architecture observed was similar to that of performance‐based measures of executive function. This observed similarity provided additional evidence for the usefulness of the BRIEF as a measure of ‘everyday’ executive function.  相似文献

This study aimed to investigate whether a child's narrative of a particular past episode would change in repeated reporting over the long term, and if so, how it would change. To answer these questions, I conducted longitudinal case studies of episodic reports by children every 2–6 months, from their early childhood to the age of 10–15 years. Criteria for inclusion were set in advance; seven episodic narratives meeting these criteria were analyzed. Two types of changes in the narratives were observed, as expected: that of including other information, and that of an event suddenly being reported after no recall for several years. Information from the children's surroundings seemed to be substantially involved in these changes in their episodic narratives. The present results also indicate that mothers' episodic memories are not always reliable and that the schema children have can influence their episodic memories.  相似文献
