“…Additionally, Nordmo et al (2020) conducted a diary study with the sample of the Royal Norwegian Navy, the results of the study showed that hardiness has a positive effect on job performance and hardiness moderates the relationship of sleep quality and job performance as well.…”

Integration of social cognitive theory and hardiness theory, this study aimed to investigate the mediating mechanism of job crafting and the direct effect of empowering leadership that causes occupational burnout with the sample from law enforcement institutions. The authors also tested the moderating effect of employee optimism and employee hardiness between the linkage of job crafting and occupational burnout. To test the proposed hypothesis of this study, 192 participants from the law enforcement institution of Punjab, Pakistan participate in this study voluntarily. The findings of the study suggest that job crafting mediates the relationship between empowering leadership and occupational burnout. Furthermore, the authors found that employee optimism and hardiness moderate the relationship between empowering leadership and occupational burnout. The result of moderated mediation analysis revealed that the indirect effect of empowering leadership on occupational burnout was weakening when employee optimism and hardiness level was high. The findings of this study declared that empowering leadership has adverse consequences on employees’ physical and psychological health that decrease the well-being and employee optimism and hardiness reduce that stress level and enhance the intrinsic motivational level. Top management of law enforcement institutions must focus especially on the psychological health of employees and provide climate and psychological training that mitigates the harmful consequences of empowering leadership. Also, the authors through this study respond to the calls of prior researches as slight researches have studied the negative consequences of empowering leadership.

“…In contrast, when the work pressure is relatively low, task performance may be less dependent of such restoration of resources and may even increase apathy and reduce performance due to a larger gap between energy levels and task demands ( Gardner, 1986 ). It is also noteworthy that sleep differs greatly from night to night for the individual officers, due to factors like noise, alarms, and weather conditions ( Nordmo et al, 2020 ). Notably, even though recovery processes contribute to replenishment of resources, we argue that sleep represents a supplementary strategy adding to the effects of physical and mental recovery, as defined in the current study.…”

Whereas previous research has focused on the link between (mental and physical) workload and task performance, less is known about the intervening mechanisms influencing this relationship. In the present study, we test the moderating roles of daily recovery and total sleep time in the relationship between work pressure and daily task performance. Using performance and recovery theories, we hypothesized that (a) work pressure relates positively to daily task performance, and that both (b) daily recovery in the form of psychological detachment and relaxation, and (c) total sleep time independently enhance this relationship. Our hypotheses were tested in a 30-day diary study with 110 officer cadets on a cross-Atlantic voyage on a Naval sail ship. The results of multilevel modeling lend support to all three hypotheses. Taken together, our findings suggest that recovery and sleep duration between shifts play a key role in the relationship between daily work pressure and task performance. We discuss the implications of these findings for the stressor-detachment model.

“…Furthermore, the completion of standard sleep diary is relatively time-consuming for shift workers, thus they may show lower compliance. This may be the reason why most researchers only required sailors or submariners to report TST or overall sleep quality in the sleep diary (Nordmo et al, 2020; Paul & Love, 2022).…”

Sleep problems among shift workers have emerged as a public health concern in recent years. However, few validation studies of self-reported sleep quality questionnaires were performed among shift workers. The present study aimed to examine the psychometric properties of the Brief Version of Pittsburgh Sleep Quality Index (B-PSQI) in a shift workers sample. In total, 443 Chinese male sailors were recruited, of whom 46.95% (n = 208) were watchstanding sailors on 18-hr working schedule at sea. All participants completed the B-PSQI, the Insomnia Severity Index (ISI), the Self-Rating Depression Scale, and Self-Rating Anxiety Scale before and after a 30-day saling. Forty watchstanding sailors were selected to wear wrist actigraphy throughout the sailing. The results showed that the B-PSQI had acceptable internal consistency reliability in different sailor groups. Confirmatory factor analysis showed optimal fit of the single-factor model of the B-PSQI in different sailor groups. Furthermore, scalar invariance between watchstanding and day-working sailors was supported, as well as longitudinal scalar invariance across time. In addition, receiver operating characteristic analysis showed that the B-PSQI yields high discrimination power to detect poor sleep quality using ISI ≥ 8 criterion. However, a lack of intermethod agreement across the B-PSQI and actigraphy was found in this study. Moreover, the total scores of B-PSQI were positively related to depression and anxiety symptoms in the present sample. The B-PSQI is a reliable and valid sleep quality measure and a useful screening tool for sleep disorders among Chinese male sailors.
