“…This finding is also borne out in laboratory tests using controlled computerized paradigms (Helton and Russell, 2015;Lim and Kwok, 2016) where rest breaks interrupt the trajectory of TOT declines. In educational settings, Sievertsen et al (2016) studied a large cohort of Danish students and found that test performance improved significantly following 20-30-min breaks during the school day. The balance of evidence is thus that rest pauses have positive effects on cognitive functioning, at least in the short term.…”

Achievement-oriented adolescents often study long hours under conditions of chronic sleep restriction, adversely affecting cognitive function. Here, we studied how napping and rest breaks (interleaved off-task periods) might ameliorate the negative effects of sleep restriction on processing speed. Fifty-seven healthy adolescents (26 female, age = 15-19 years) participated in a 15-day live-in protocol. All participants underwent sleep restriction (5 h time-in-bed), but were then randomized into two groups: one of these groups received a daily 1-h nap opportunity. Data from seven of the study days (sleep restriction days 1-5, and recovery days 1-2) are reported here. The Blocked Symbol Decoding Test, administered once a day, was used to assess time-on-task effects and the effects of rest breaks on processing speed. Controlling for baseline differences, participants who took a nap demonstrated faster speed of processing and greater benefit across testing sessions from practice. These participants were also affected significantly less by time-on-task effects. In contrast, participants who did not receive a nap benefited more from the rest breaks that were permitted between blocks of the test. Our results indicate that napping partially reverses the detrimental effects of sleep restriction on processing speed. However, rest breaks have a greater effect as a countermeasure against poor performance when sleep pressure is higher. These data add to the growing body of evidence showing the importance of sleep for good cognitive functioning in adolescents, and suggest that more frequent rest breaks might be important in situations where sleep loss is unavoidable.

“…Many psychological and occupational medicine studies indicate the crucial significance of fatigue: the short-term impact on the ongoing performance of duties in the form of, for example, attention alteration or efficiency reduction (e.g., in the work of a driver, flight controller or a hospital staff member) [1]; the long-term impact related to "burnout" [2] and absences from work [3]. Increasing data indicate a growing problem with fatigue among students [4,5].…”

Objectives: The Chalder Fatigue Questionnaire (CFQ) was developed to measure fatigue in 2 dimensions: physical and mental. The aim of the study was to translate, adapt and evaluate the psychometric properties of the Polish version of the CFQ (CFQ-PL). Material and Methods: The process of translation was conducted using a forward and backward translation procedure. After cultural adaptation, the psychometric properties of the CFQ-PL were evaluated. Participants of the study were healthy individuals: medical students (N = 304) and pregnant women (pregnancy without complications, N = 925). The reliability and validity were estimated using fatigue numerical rating scales, the Beck Depression Inventory and the State-Trait Anxiety Inventory. To examine the factor structure of the CFQ-PL, a confirmatory factor analysis was conducted. Results: The internal consistency of the CFQ-PL was similar to the original version (Cronbach's α 0.85-0.91). Statistically significant correlations between the CFQ-PL and the current fatigue level, average fatigue and the sleepiness level (measured using numerical rating scales), as well as the intensity of depression and anxiety symptoms, all confirming the validity of the adapted scale. Using a confirmatory factor analysis, it was determined that a 1-factor model did not fit the data well. A 2-factor model with a correlation between mental and physical factors fitted better than the 1-factor model, yet fit indices revealed a poor fit. Using a 2-factor model with added covariance between items -1 (problems with fatigue), 2 (resting more), 9 (slips of the tongue), 10 (finding the correct word) -resulted in acceptable fit indices in both groups of participants. Conclusions: After the process of translation, adaptation and validation of the CFQ-PL, it is now available for use under Polish conditions. This study provided evidence for structural validity of the 2-factor model of the 11-item version. Int J Occup Med Environ Health. 2020;33(1):67 -76

“…However, few such studies exist, and evidence is contradictory, with some studies providing evidence for real-world ego-depletion effects (e.g. Dai, Milkman, Hofmann, & Staats, 2015;Sievertsen, Gino, & Piovesan, 2016) and others not (e.g. O'Connell et al, 2008;Randles, Harlow, & Inzlicht, 2017).…”

The large body of research used to support ego‐depletion effects is currently faced with conceptual and replication issues, leading to doubt over the extent or even existence of the ego‐depletion effect. By using within‐person designs in a laboratory (Study 1; 187 participants) and an ambulatory assessment study (Study 2; 125 participants), we sought to clarify this ambiguity by investigating whether prominent situational variables (such as motivation and affect) or personality traits can help elucidate when ego depletion can be observed and when not. Although only marginal ego‐depletion effects were found in both studies, these effects varied considerably between individuals, indicating that some individuals experience self‐control decrements after initial self‐control exertion and others not. However, neither motivation nor affect nor personality traits such as trait self‐control could consistently explain this variability when models were applied that controlled for variance due to targets and the depletion manipulation (Study 1) or days (Study 2) as well as for multiple testing. We discuss how the operationalization and reliability of our key measures may explain these null effects and demonstrate that alternative metrics may be required to study the consequences of the consecutive exertion of self‐control. © 2019 European Association of Personality Psychology
