This study investigated potential antecedents of team job crafting defined as the extent to which team members engage together in increasing (social and structural) job resources and challenges, and decreasing hindering job demands. Mindful of the teamwork literature, we hypothesized that individual employee factors (self-efficacy for teamwork, daily affect), team features (team cohesion, climate) and the organizational context of teams (engaging leadership and organizational resources for teamwork) relate positively to daily team job crafting behaviour. Data were collected among 46 multi-professional rehabilitation teams whose members completed two daily surveys after their weekly meetings. Multilevel regression analyses showed that self-efficacy for teamwork and team members’ positive affect were positively associated with team job crafting behaviour at the individual (within-team) level. In addition, a team climate characterized by a clear vision of the teams’ targets, supportiveness and innovation and connecting leadership were positively related to daily team job crafting at both the within- and between-team levels of the data. Overall, the study offers novel insights into the antecedents of teams’ daily job crafting behaviours. For practice, the results suggest that actions and interventions conducive to positive team processes offer the most promising route to enhancing team job crafting behaviour. 相似文献

This pilot randomized controlled trial (RCT) investigated benefits of omega-3 fatty acid supplementation and Individual-Family Psychoeducational Psychotherapy (PEP; a family-focused, cognitive-behavioral therapy) for behavior problems among youth with depression. Participants aged 7–14 with DSM-IV-TR depressive disorders (N = 72; 56.9 % male) were randomized to 1 of 4 treatment conditions: PEP + omega-3, PEP monotherapy (with pill placebo), omega-3 monotherapy, or placebo (without active intervention). At screen, baseline, and 2, 4, 6, 9, and 12 weeks post-baseline, parents completed the SNAP-IV, which assesses attention-deficit/hyperactivity disorder symptoms, oppositional defiant disorder symptoms, and overall behavior problems. At screen, baseline (randomization), 6 and 12 weeks, parents completed the Eyberg Child Behavior Inventory (ECBI), which includes Intensity and Problem scales for child behavior problems. Youth who had a completed SNAP-IV or ECBI for at least two assessments during treatment (n = 48 and 38, respectively) were included in analyses of the respective outcome. ClinicalTrials.gov.:NCT01341925. Linear mixed effects models indicated a significant effect of combined PEP + omega-3 on SNAP-IV Total (p = 0.022, d = 0.80) and Hyperactivity/Impulsivity trajectories (p = 0.008, d = 0.80), such that youth in the combined group saw greater behavioral improvement than those receiving only placebo. Similarly, youth in combined treatment had more favorable ECBI Intensity trajectories than youth who received no active treatment (p = 0.012, d = 1.07). Results from this pilot RCT suggest that combined PEP + omega-3 is a promising treatment for co-occurring behavior symptoms in youth with depression. 相似文献

What's Context Got to Do with It? Comparative Difficulty of Test Questions Influences Metacognition and Corrected Scores for Formula‐scored Exams 下载免费PDF全文
Michelle M. Arnold Kristin Graham Sinead Hollingworth‐Hughes 《Applied cognitive psychology》2017,31(2):146-155
Summary: On formula‐scored exams students receive points and penalties for correct and incorrect answers, respectively, but they can avoid the penalty by withholding incorrect answers. However, test‐takers have difficulty strategically regulating their accuracy and often set an overly conservative metacognitive response bias (e.g., Higham, 2007). The current experiments extended these findings by exploring whether the comparative difficulty of surrounding test questions (i.e., easy vs. hard)—a factor unrelated to the knowledge being tested—impacts metacognitive response bias for medium‐difficulty test questions. Comparative difficulty had no significant influence on participants' ability to choose correct answers for medium questions, but it did affect willingness to report answers and confidence ratings. This difference carried over to corrected scores (scores after penalties are applied) when comparative difficulty was manipulated within‐subjects: Scores were higher in the hard condition. Results are discussed in terms of implications for interpreting formula‐scored tests and underlying mechanisms of performance.Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

We investigated the effect of prior acute stress on colonic permeability induced by a chemical irritant known to induce symptoms similar to inflammatory bowel disease in rodents. Adult male rats (n = 12) were stressed by a single session of ten unpredictable, uncontrollable foot shocks, and half were home cage controls (n = 12). Twenty-nine days later, half of each treatment group was exposed to 4% DSS (dextran sulphate sodium) solution in their drinking water for 48 hours while half received pure water over two periods separated by 17 days. After food deprivation overnight and light isoflurane anaesthesia the following morning, the animals were given a colonic infusion of 2000 nCi (nanocurie) 51CrEDTA (51Cr-labelled ethylenediaminetetraacetic acid) and then placed individually in metabolic cages for a six hours continuous urine collection. Radioactivity in urine was measured by a gamma counter and percentage recovery of 51CrEDTA calculated as an indicator of colonic mucosal permeability. Results concluded that pre-shocked animals exposed to DSS showed significantly higher mucosal permeability than the pre-shocked animals given water, and the non-shocked animals given either DSS or water. Pre-shock in combination with two exposures to a chemical irritant separated by 17 days had a pronounced effect on colonic permeability, indicating that stress should be considered a possible initiating or contributory factor to increased intestinal permeability related to a mucosal challenge. 相似文献

The present study is an examination of the influence of rater characteristics as a source of bias in job characteristics information, as gleaned from the Job Diagnostic Survey (JDS). Participants (N=133) completed an initial JDS for own job characteristics. Non‐incumbents (n=104) then completed a secondary JDS in order to rate incumbents' job characteristics. Non‐incumbents' personality dimensions, own job characteristics, job satisfaction level, and incumbent satisfaction level were hypothesized as predictors of ratings of job characteristics of incumbents. Results indicate that two characteristics, job autonomy and dealing with others, were influenced by non‐incumbents standing on these characteristics, and demonstrated evidence of the false consensus effect. Limitations and implications for interpreting job information are discussed. 相似文献

The present study examined the effects of ovariectomy and subsequent estradiol replacement on learning in young adult rats using a set of instrumental avoidance paradigms differing in the nature and extent of prior experience in the learning context. Thus, one group of animals was placed directly into avoidance learning (AV). A second group was trained on an appetitive task first, and then transferred into the aversive context (AP-AV). The third group was exposed to the training context without any specific appetitive response requirement, and then required to learn an active avoidance response (Context-AV). We found that estradiol (OVX+E) impaired avoidance acquisition in all cases relative ovariectomized controls (OVX). In contrast, while avoidance learning is improved following appetitive training or context exposure in both OVX+E and OVX animals, the OVX+E animals profit to a greater extent from the appetitive or context experience than do the OVX controls. We suggest that this difference may be due to enhanced attentional processes or improved hippocampal processing of contextual factors. Thus, estradiol negatively influences simple associative avoidance learning in ovariectomized rats, but appears to promote positive transfer. 相似文献

A theoretical distinction within self‐control, between stop control and start control, was investigated in two studies. Study 1 consisted of a pilot study in which expert ratings of existing self‐control items were used to distinguish between stop and start control items and a confirmatory factor analyses of these items using a student sample (N = 474). Also, stop and start control were related to overall affect and behavioural outcomes. Stop control was negatively related to negative affect, whereas start control was positively related to positive affect. Study 2 (N = 226) replicated some of these findings; stop control was the best predictor (?) of smoking and alcohol consumption whereas start control was the best predictor (+) of exercising and studying.
