On The “Bubble” Of Burnout's Prevalence Estimates, Eric Laurent, Irvin Sam Schonfeld, Renzo Bianchi, Laura Hawryluck, Peter G. Brindley
On The “Bubble” Of Burnout's Prevalence Estimates, Eric Laurent, Irvin Sam Schonfeld, Renzo Bianchi, Laura Hawryluck, Peter G. Brindley
Publications and Research
Hawryluck and Brindley (2018) addressed the issue of burnout—a syndrome thought to be induced by job stress—among critical care medicine (CCM) practitioners. Although we agree that the practice of CCM can be stressful, relying on burnout as an indicator of the practitioners’ response to occupational adversity is unwarranted. Despite its popularity, burnout remains poorly defined. Disconcertingly, investigators have widely relied on the Maslach Burnout Inventory (MBI) for “diagnosing” burnout in spite of the fact that the MBI is not a diagnostic instrument.Experiencing fatigue or distancing oneself from one’ work—what burnout is about—is not necessarily a sign of ill-being in itself. …
Is A Meta-Analytic Approach To Burnout’S Prevalence Timely?, Eric Laurent, Irvin Sam Schonfeld, Renzo Bianchi
Is A Meta-Analytic Approach To Burnout’S Prevalence Timely?, Eric Laurent, Irvin Sam Schonfeld, Renzo Bianchi
Publications and Research
Cañadas‐De la Fuente et al. performed a meta‐analysis of the prevalence of emotional exhaustion, depersonalization, and diminished personal accomplishment—the three definitional components of the burnout syndrome—among nursing professionals working in oncology units. All in all, their meta‐analysis was inconclusive because of the very state of burnout research. Because there is mounting evidence that burnout is a depressive condition, we recommend that investigators focus on depression, rather than burnout, in occupational health research and practice.
Burnout And Depressive Symptoms Are Not Primarily Linked To Perceived Organizational Problems, Renzo Bianchi, Eric Mayor, Irvin Sam Schonfeld, Eric Laurent
Burnout And Depressive Symptoms Are Not Primarily Linked To Perceived Organizational Problems, Renzo Bianchi, Eric Mayor, Irvin Sam Schonfeld, Eric Laurent
Publications and Research
In this 257-participant study (76% female; mean age: 44.84), we examined two ideas that are widespread among burnout researchers: (a) the idea that burnout is primarily related to occupational-level factors; and (b) the idea that burnout should be considered a sentinel indicator in research on negative occupational outcomes. We investigated the links between burnout and a series of generic and work-related variables, namely, depressive symptoms, neuroticism, extraversion, effort-reward imbalance in the job (ERI), social support at work (SSW), and turnover intention. Burnout was assessed with the Shirom-Melamed Burnout Measure, depressive symptoms with the PHQ-9, neuroticism and extraversion with the NEO-Five …

Objectives: This study investigated the effects of sleep deprivation on perception of task difficulty and use of heuristics (mental shortcuts) compared to naturally-experienced sleep at home. Methods: Undergraduate students were screened and assigned through block-random assignment to Naturally-Experienced Sleep (NES; n=19) or Total Sleep Deprivation (TSD; n=20). The next morning, reported fatigue, perception of task difficulty, and use of “what-is-beautiful-is-good,” “greedy algorithm,” and “speed-accuracy trade-off ” heuristics were assessed. Results: NES slept for an average of 354.74 minutes (SD=72.84), or 5.91 hours. TSD rated a reading task as significantly more difficult and requiring more time than NES. TSD was …

The American Psychological Association expects graduating psychology majors to be able to read and summarize complex ideas accurately, and to communicate effectively as writers. However, undergraduates often have little explicit instruction and practice in reading and summarizing academic articles, or in psychology-specific writing practices. Consequently, students’ skills as academic readers and writers often fail to meet expectations. In our large public university, writing problems were prevalent in our biological psychology classes. When asked to read and summarize primary sources, students reported that the articles were very difficult to understand, papers commonly included plagiarism, and many students withdrew from the classes. …

Burnout Research: Eyes Wide Shut, Irvin Sam Schonfeld, Eric Laurent, Renzo Bianchi
Publications and Research
In a study published in a recent issue of Critical Care Medicine, Colville and Smith (2017) found modest overlap between burnout and depression and assumed that burnout and depression are distinct entities. For four reasons, we think that the study is seriously flawed. First, Colville and Smith assessed burnout symptoms with an abbreviated version of the Maslach Burnout Inventory (MBI), the psychometric properties of which are unclear. Second, they used clinically and theoretically arbitrary cutoff scores for categorizing burnout, a modus operandi that, unfortunately, has become commonplace in studies of medical professionals. Third, participants could be categorized as “burned out” …
Burnout Syndrome And Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent
Burnout Syndrome And Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent
Publications and Research
In this chapter, we proposed an overview of burnout, from the introduction of the construct in the mid-1970s to the growing realization that the syndrome was better conceived of as a depressive condition. Recent studies have shown that the distinction between burnout and depression is problematic, both theoretically and empirically. The history of burnout research suggests that transdisciplinary communication and methodological standards should be strengthened to avoid the proliferation of constructs that, in fact, refer to the same phenomena. Construct proliferation, a transgression of the scientific canon of parsimony, is considered a major problem today because it undermines theory building …
Interpretation Bias Toward Ambiguous Information In Burnout And Depression, Renzo Bianchi, Eric Laurent, Irvin Sam Schonfeld, Jay Verkuilen, Chantal Berna
Interpretation Bias Toward Ambiguous Information In Burnout And Depression, Renzo Bianchi, Eric Laurent, Irvin Sam Schonfeld, Jay Verkuilen, Chantal Berna
Publications and Research
Burnout has been defined as a job-related syndrome combining pervasive fatigue and loss of motivation. In recent years, evidence has mounted that burnout may reflect a depressive condition. In this study, we expanded on past investigations of burnout-depression overlap by focusing on interpretation biases toward ambiguous information among the two entities. We conducted a web-based study involving 1056 participants (83% female; mean age: 42.87). Burnout symptoms were assessed with the Shirom-Melamed Burnout Measure and depressive symptoms with the PHQ-9. The Ambiguous Scenarios Test (AST), a measure of interpretation bias validated among dysphoric individuals, was the outcome of interest. The AST …
What Is The Difference Between Depression And Burnout? An Ongoing Debate, Irvin Sam Schonfeld, Renzo Bianchi, Stefano Palazzi
What Is The Difference Between Depression And Burnout? An Ongoing Debate, Irvin Sam Schonfeld, Renzo Bianchi, Stefano Palazzi
Publications and Research
Il burnout è concepito come una sindrome che si sviluppa in risposta a condizioni di lavoro cronicamente avverse. Si ritiene che il burnout comporti esaurimento emotivo, depersonalizzazione e riduzione della realizzazione personale. Storicamente, tuttavia, il burnout è stato difficile da separare dalla depressione. In effetti, i sintomi del burnout coincidono con i sintomi della depressione. L'evidenza della validità discriminante del burnout nei confronti della depressione è debole, sia a livello empirico sia a livello teorico. L'esaurimento emotivo, il nucleo del burnout, riflette una combinazione di umore depresso e affaticamento / perdita di energia e si correla molto bene con altri …

A Neglected Problem In Burnout Research, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent
Publications and Research
Although we share with Eckleberry-Hunt et al. (2018) some of their criticisms regarding the problematic conceptualization of burnout, we are perplexed by the authors’ silence regarding burnout–depression overlap, which is arguably the most troubling problem attached to the burnout construct. The extensive research suggests that burnout reflects a combination of depressive responses. The emotional exhaustion component of burnout involves fatigue and depressed mood, two diagnostic criteria for depressive disorders. Maslach et al. (2001) wrote that there is “a predominance of dysphoric symptoms” in burnout. Depersonalization symptoms are commonly found in depressed individuals. Diminished personal accomplishment reflects well-known depressive manifestations of …

Burnout-Depression Overlap: Nomological Network Examination And Factor-Analytic Approach, Renzo Bianchi, Irvin Sam Schonfeld
Publications and Research
Burnout has been defined as a condition in which individuals are left exhausted by a long-term confrontation with unmanageable job stressors. The question of whether burnout reflects anything other than depressive responses to unresolvable stress remains an object of debate. In this 911-participant study (83% female; mean age: 42.36), we further addressed the issue of burnout-depression overlap. Burnout was assessed with the exhaustion subscale of the Maslach Burnout Inventory-General Survey (MBI-GS) and depression with the PHQ-8. The relationships of burnout and depression with three jobrelated variables – illegitimate work tasks, work-nonwork interference, and job satisfaction – and three “context-free” variables …
When We Say 'Physician Burnout,' We Really Mean Depression, Irvin Sam Schonfeld
When We Say 'Physician Burnout,' We Really Mean Depression, Irvin Sam Schonfeld
Publications and Research
There has been controversy regarding the extent to which burnout overlaps depression. I enumerate eight reasons explaining to why depression is at the heart of burnout. Some of these reasons pertain to the highly similar work-related causes of burnout and depression, burnout adherents' faulty categorical and dimensional conceptualizations of burnout and depression, problematically high correlations between emotional exhaustion (the core of burnout) and depressive symptoms, research on physicians and dentists that underline burnout-depression overlap, and the problem of alexithymia being similarly related to burnout and depression. Suggestions for addressing the problem of burnout-depression among physicians are presented.

Increasing numbers of Hispanic immigrants are entering the US and learning American–English (AE) as a second–language (L2). Previous studies investigating the relationship between AE and Spanish vowels have revealed an advantage for early L2 learners for their accuracy of L2 vowel perception. Replicating and extending such previous research, this study examined the patterns with which early and late Spanish–English bilingual adults assimilated naturally-produced AE vowels to their native vowel-inventory and the accuracy with which they discriminated the vowels. Twelve early Spanish–English bilingual, 12 late Spanish–English bilingual, and 10 monolingual listeners performed perceptual-assimilation and categorical-discrimination tasks involving AE /i,ɪ,ɛ,ʌ,æ,ɑ,o/. Early bilinguals …

Decisional Bias As Implicit Moral Judgment, Toni Spring, Herbert D. Saltzstein
Publications and Research
Decisional bias (false alarm rate) when judging the guilt/innocence of a suspect is offered as an implicit measure of moral judgment. Combining two data sets, 215 participants, ages 10-12, 13-15, and 16-18 watched the visually identical film involving a person setting a fire, framed either as (a) intentional but not resulting in a fire (BI-NF), (b) unintentional but resulting in a major fire (NI-F), or (c) intentional and resulting in a major fire (BI-F). After watching the film, participants identified seriatim who of six individuals was the perpetrator and how certain they were. The data were subjected to a signal …

The current study assesses the factor structure and construct validity of the self-reported Inventory of Callous±Unemotional Traits (ICU) in 637 Chinese community adults (mean age = 25.98, SD = 5.79). A series of theoretical models proposed in previous studies were tested through confirmatory factor analyses. Results indicated that a shortened form that consists of 11 items (ICU-11) to assess callousness and uncaring factors has excellent overall fit. Additionally, correlations with a wide range of external variables demonstrated that this shortened form has similar construct validity compared to the original ICU. In conclusion, our findings suggest that the ICU-11 may be …

Regulating Rumination By Anger: Evidence For The Mutual Promotion And Counteraction (Mpmc) Theory Of Emotionality, Jun Zhan, Fan Tang, Mei He, Jin Fan, Jing Xiao, Chang Liu, Jing Luo
Publications and Research
Unlike the strategy of cognitive regulation that relies heavily on the top-down control function of the prefrontal cortex (PFC), which was recently found may be critically impaired in stressful situations, traditional Chinese philosophy and medicine views different types of emotionality as having mutual promotion and counteraction (MPMC) relationships, implying a novel approach that requires less cognition to emotional regulation. Actually, our previous studies have indicated that anger responses could be successfully regulated via the induction of sadness, and this efficiency could not be influenced by stress, thus providing evidences for the hypothesis of “sadness counteracts anger” (SCA) proposed by the …

Auditory evoked potentials (AEP) reflect spectro-temporal feature changes within the spoken word and are sufficiently reliable to probe deficits in auditory processing. The current research assessed whether attentional modulation would alter the morphology of these AEPs and whether native-language experience with phoneme sequences would influence the effects of attention. Native-English and native-Polish adults listened to nonsense word pairs that contained the phoneme sequence onsets /st/, /sət/, /pət/ that occur in both the Polish and English languages and the phoneme sequence onset /pt/ that occurs in the Polish language, but not the English language. Participants listened to word pairs within two …

Saccade Adaptation Deficits In Developmental Dyslexia Suggest Disruption Of Cerebellar-Dependent Learning, Edward G. Freedman, Sophie Molholm, Michael J. Gray, Daniel Belyusar, John J. Foxe
Publications and Research
Background: Estimates of the prevalence of developmental dyslexia in the general population range from 5% to as many as 10%. Symptoms include reading, writing, and language deficits, but the severity and mix of symptoms can vary widely across individuals. In at least some people with dyslexia, the structure and function of the cerebellum may be disordered. Saccadic adaptation requires proper function of the cerebellum and brainstem circuitry and might provide a simple, noninvasive assay for early identification and sub-phenotyping in populations of children who may have dyslexia.
Methods: Children between the ages of 7 and 15 served as participants in …

Publications and Research
Introduction: Food insecurity is a major global contributor to developmental origins of adult disease. The allostatic load of maternal food uncertainty from variable foraging demand (VFD) activates corticotropin-releasing factor (CRF) without eliciting hypothalamic-pituitary-adrenal (HPA) activation measured on a group level. Individual homeostatic adaptations of the HPA axis may subserve second-order homeostasis, a process we provisionally term “social allostasis.” We postulate that maternal food insecurity induces a “superorganism” state through coordination of individual HPA axis response.
Methods: Twenty-four socially-housed bonnet macaque maternal-infant dyads were exposed to 16 weeks of alternating two-week epochs of low or high foraging demand shown to compromise …

Selfie-Takers Prefer Left Cheeks: Converging Evidence From The (Extended) Selfiecity Database, Lev Manovich, Vera Ferrari, Nicola Bruno
Publications and Research
According to previous reports, selfie takers in widely different cultural contexts prefer poses showing the left cheek more than the right cheek. This posing bias may be interpreted as evidence for a right-hemispheric specialization for the expression of facial emotions. However, earlier studies analyzed selfie poses as categorized by human raters, which raises methodological issues in relation to the distinction between frontal and three-quarter poses. Here, we provide converging evidence by analyzing the (extended) selfiecity database which includes automatic assessments of head rotation and of emotional expression. We confirm a culture- and sex-independent left-cheek bias and report stronger expression of …

Publications and Research
Introduction: Memory deficits characterize Alzheimer’s dementia and the clinical precursor stage known as mild cognitive impairment. Nonpharmacologic interventions hold promise for enhancing functioning in these patients, potentially delaying functional impairment that denotes transition to dementia. Previous findings revealed that mnemonic strategy training (MST) enhances long-term retention of trained stimuli and is accompanied by increased blood oxygen level–dependent signal in the lateral frontal and parietal cortices as well as in the hippocampus. The present study was designed to enhance MST generalization, and the range of patients who benefit, via concurrent delivery of transcranial direct current stimulation (tDCS).

In many songbird species, males sing to attract females and repel rivals. How can gregarious, non-territorial songbirds such as zebra finches, where females have access to numerous males, sustain monogamy? We found that the dopaminergic reward circuitry of zebra finches can simultaneously promote social cohesion and breeding boundaries. Surprisingly, in unmated males but not in females, striatal dopamine neurotransmission was elevated after hearing songs. Behaviorally too, unmated males but not females persistently exchanged mild punishments in return for songs. Song reinforcement diminished when dopamine receptors were blocked. In females, we observed song reinforcement exclusively to the mate’s song, although their …

Previous studies have reported the failure of cognitive emotion regulation (CER), especially in regulating unpleasant emotions under stress. The underlying reason for this failure was the application of CER depends heavily on the executive function of the prefrontal cortex (PFC), but this function can be impaired by stress-related neuroendocrine hormones. This observation highlights the necessity of developing selfregulatory strategies that require less top-down cognitive control. Based on traditional Chinese philosophy and medicine, which examine how different types of emotions promote or counteract one another, we have developed a novel emotion regulation strategy whereby one emotion is used to alter another. …

Our research purpose was to assess research addressing relationships between dress and sex. Our review was focused on a 25 years span (i.e., 1990–2015) and on empirical research utilizing human participants published in refereed journals. Three main areas of research emerged: (1) dress used as cue to sexual information, (2) dress and sexual violence, and (3) dress, sex, and objectification. Our analyses revealed parents do invest their young children with sex-typed dress however sometimes children demand to wear such dress. Some women intentionally use dress to communicate sexual information but inferences about women who wear sexy dress can be misinterpreted …
