Psychological science remains unclear about how individuals' trait perfectionism impacts their performance—is more perfectionism linearly better or does too perfect backfire? The present study ...investigates a potentially non-linear relationship and its underlying mediators. Based on the two-dimensional model of perfectionism that distinguishes perfectionistic concerns (PC) versus strivings (PS), we investigate the (non-)linear relationships of perfectionism and performance in the letter detection task. Additionally, we experimentally examined whether time pressure would moderate these findings. Our study results (N = 229) establish non-linearity: a quadratic function in the form of an inverted U-shape best explains the relationship between perfectionistic concerns and performance. Contrary to our hypothesis, perfectionistic strivings predicted task performance linearly but negatively. Upon further examination, we also found empirical support for a combinatory effect of both dimensions: Only individuals high in PC showed the negative effect of PS on task performance. Although performance differed in the timed versus untimed task, time pressure did not moderate the (non-)linear relationships of PS or PC on performance. Multiple mediation analyses revealed that perceived distress, rumination, and effort mediated the quadratic relationships of perfectionistic concerns. Overall, our results question the strict disentanglement of perfectionistic dimensions and emphasise the usefulness of a more holistic approach.

BackgroundPreliminary unpublished results of the survey of carbapenem- and/or colistin-resistant Enterobacterales (CCRE survey) showed the expansion of carbapenemase-producing
(CPKP) sequence type ...(ST) 39 in 12 of 15 participating Greek hospitals in 2019.AimWe conducted a rapid survey to determine the extent of spread of CPKP high-risk clones in Greek hospitals in 2022 and compare the distribution of circulating CPKP clones in these hospitals since 2013.MethodsWe analysed whole genome sequences and epidemiological data of 310
isolates that were carbapenem-resistant or 'susceptible, increased exposure' from Greek hospitals that participated in the European survey of carbapenemase-producing
(EuSCAPE, 2013-2014), in the CCRE survey (2019) and in a national follow-up survey (2022) including, for the latter, an estimation of transmission events.ResultsFive
STs including ST258/512 (n = 101 isolates), ST11 (n = 93), ST39 (n = 56), ST147 (n = 21) and ST323 (n = 13) accounted for more than 90% of CPKP isolates in the dataset. While ST11, ST147 and ST258/512 have been detected in participating hospitals since 2013 and 2014, KPC-2-producing ST39 and ST323 emerged in 2019 and 2022, respectively. Based on the defined genetic relatedness cut-off, 44 within-hospital transmission events were identified in the 2022 survey dataset, with 12 of 15 participating hospitals having at least one within-hospital transmission event.ConclusionThe recent emergence and rapid spread of new high-risk
clones in the Greek healthcare system related to within-hospital transmission is of concern and highlights the need for molecular surveillance and enhanced infection prevention and control measures.
