Grounded in the conservation of resources theory, this study proposes the mechanisms and conditions under which customer mistreatment affects employee proactive behavior. This study focuses on insomnia as a mediating mechanism and resilience as a boundary condition for the indirect effect of customer mistreatment on employee proactive behavior via insomnia.

We conducted a single survey in two phases, with a time lag of three weeks, among 302 frontline South Korean employees. The data collected from these two points were then analyzed using hierarchical regression analysis and the PROCESS macro.

The findings demonstrated that there was a significant negative relationship between customer mistreatment and employee proactive behavior, and this relationship was mediated by insomnia. Furthermore, the results revealed that resilience moderates both the effect of customer mistreatment on insomnia and the indirect effect of customer mistreatment on employee proactive behavior through insomnia.

This research primarily focuses on Korean frontline workers, potentially limiting cultural generalizability. The reliance on self-reported data may introduce common method bias. Future studies should diversify participant demographics and utilize multi-source feedback to validate findings. Grounded in the Conservation of Resource Theory, this study underscores the neglected linkage between customer mistreatment and proactive behavior, especially in frontline employees. We introduce insomnia as a pivotal mediator, deepening our understanding of why mistreatment dampens proactivity. Additionally, we spotlight the role of resilience, revealing its buffering effect against mistreatment’s adverse outcomes.

Organizations should be aware of the detrimental effects of customer mistreatment on frontline employees, as it can hamper proactive behavior, primarily through the exacerbation of insomnia. Implementing resilience-training programs can be a proactive step, offering frontline staff tools to buffer against such negative outcomes. Managers are encouraged to recognize and address instances of customer mistreatment and prioritize employee well-being, which in turn can foster a more proactive and resilient workforce, enhancing organizational performance and customer satisfaction.

This study underscores the broader societal challenge of customer mistreatment in the service sector, highlighting its ripple effects on employee well-being and proactive behavior. It sheds light on the importance of fostering respectful interactions in public and private spaces, emphasizing mutual respect between customers and service providers. Recognizing the adverse impacts of mistreatment can prompt societal discourse on workplace ethics and encourage organizations to advocate for their employees' rights. Ultimately, nurturing a culture that condemns customer mistreatment can lead to healthier work environments, benefitting both employees and society at large.

This study presents a novel approach by investigating the impact of customer mistreatment on employee proactive behavior, considering insomnia as a mediator, a perspective that has received limited attention in existing literature. Additionally, it introduces the concept of resilience as a moderator, offering fresh insights into how individual resilience levels can affect the relationship between customer mistreatment and proactive behavior. The research goes beyond traditional analyses of workplace dynamics to explore the broader implications of these interactions on personal well-being and sleep patterns. Through the application of a moderated-mediation framework, this study enhances understanding of complex organizational behavior dynamics, particularly in the service sector, and provides valuable implications for both theoretical understanding and practical application.

Post-migration stress is an important aspect of refugees’ mental health, but little is known about the relationship with insomnia. The purpose of this study was to investigate the assication between different post-migration stress factors and insomnia among Syrian refugees living in Norway.

The authors analysed survey data from the REFUGE study with 873 Syrian adults who resettled in Norway between 2015 and 2017. Potential participants were randomly selected from The Norwegian Population Register. Insomnia was measured using the Bergen Insomnia Scale. Perceived-discrimination, navigation difficulties, financial strain and loss of social status were measured via the refugee post-migration stress scale. The authors ran logistic regression analyses, controlling for socio-demographics, potentially traumatic experiences and symptoms of post-traumatic stress.

Overall, 59% (95% CI, 56%–62%) of the sample reported experiencing insomnia. In the fully-adjusted model, only financial strain and navigation difficulties were significantly associated with increased odds of insomnia. Loss of social status was also related to insomnia but only before adjusting for symptoms of post-traumatic stress.

Financial strain and navigation difficulties appear to be the most important post-migration stress factors in terms of insomnia among Syrian refugees living in Norway. Ameliorating these difficulties could potentially reduce insomnia among refugees. Since insomnia is a risk factor for the subsequent development of post-traumatic stress and depression, it is important to prevent or improve symptoms of insomnia among Syrian refugees, especially considering the high prevalence found in this study.

Insomnia is highly prevalent in prisoners. The purpose of this paper is a review of research evidence on interventions with sleep as an outcome (2000 to 2020) and rates of insomnia prevalence and associated factors in prisons (2015 to 2020).

An internet-based search used Medline, PubMed, PsycINFO (EBSCOhost), Embase, Web of Science and Scopus. Seven interventions and eight sleep prevalence or sleep-associated factor papers were identified.

Intervention research was very limited and the quality of the research design was generally poor. Interventions such as cognitive behavioural therapy for insomnia (CBT-I), yoga and mindfulness can be beneficial in a prison setting. This review identified a high prevalence of insomnia in prisons across the world, which was supported by recent evidence. Factors associated with insomnia include anxiety, depression, post-traumatic stress disorder, personality disorder and pain.

There is a need for appropriately powered randomised control trials of CBT-I in prisons and a need to use objective measures of sleep quality.

Due to a lack of an up-to-date review, this paper fulfils the need for a review of the evidence on interventions in prison settings with sleep as an outcome, rates of insomnia prevalence and associated factors in prisons.

This study aims to determine the prevalence of insomnia as well as its association with the quality of life of the inmates in a Nigerian prison. Prisoners are a disadvantaged group of people whose needs are often unmet. Many authors have focussed on investigating the prevalence and pattern of psychiatric morbidity, as well as substance use among prisoners. However, sleep disorders, which can predispose or precipitate psychiatric disorders, have been largely neglected in research. The relationship between insomnia and quality of life (QoL) among the general population has been documented but similar investigations have yet to be conducted among the prisoner population.

This was a cross-sectional study with 300 male prisoners at the Ibara prison, Abeokuta, Nigeria who were not diagnosed with depressive, generalized anxiety or post-traumatic stress disorders. Each respondent was interviewed with a sociodemographic proforma, Insomnia module of the Schedule for Clinical Assessment in Neuropsychiatry and the brief World Health Organisation Quality of Life questionnaire.

About half of the respondents (45.7%) met diagnostic criteria for insomnia. A diagnosis of insomnia and some sleep-related variables were significantly associated with QoL.

All the possible correlates of insomnia could not be investigated. Further research should be conducted to identify more correlates and investigate the impact of insomnia on prisoners’ lives.

Improvement of prison climate (relationships in prison, safety and order, contact with the outside world, facilities, meaningful activities and autonomy) may mitigate insomnia among prisoners. Prison psychiatry in Nigerian correctional centres should be made a priority.

The findings have brought to light the need to address the current social welfare system in place for Nigerian correctional centres.

The study provided information on the prevalence of insomnia and poor QoL among prisoners in a Nigerian correctional facility.

Although ageing itself does not lead to insomnia, changes in sleep architecture (the ‘typical’ physiological progression from wakefulness to deep sleep) and health status create a vulnerability to the development of insomnia, which can be precipitated by a trigger event. This review highlights some of the problems associated with insomnia in older people and offers insights into the possible approaches to stop insomnia from becoming a ‘rite of passage’. The main conclusion from this review however, is that sleep research focusing specifically on the ageing population is badly needed, alongside a unified diagnostic system and research structure (Leger, 2000). These findings are also discussed in relation to both healthcare policy and practice.

This paper aims to outline the literature that situates sleep as a public health concern. In particular, it discusses the bi‐directional relationship between insomnia and mental health.

This paper reviews and presents the findings of other relevant research, relating the discussion to policy and practice.

Getting good quality sleep is essential, but insomnia is a huge problem and may be the most commonly reported mental health complaint in the UK. Mental health influences insomnia, and insomnia can lead to mental health problems. Sleep medication is a commonly prescribed treatment for insomnia, but evidence from robust research suggests that cognitive behavioural therapy for insomnia (CBTI) is the most successful treatment for chronic insomnia.

GPs need evidence‐based information on the importance and benefits of sleep and to be able to recognise sleep problems in primary care. CBTI needs to be represented in NICE guidance for insomnia. CBT‐influenced methods could be implemented as low level interventions as part of a stepped care framework.

Reviewing the academic literature on sleep problems related to mental health reinforces the importance of sleep as a health issue, which can be assessed in primary care as appropriate.

Insomnia is highly prevalent and has severe negative consequences, yet help‐seeking remains low. Cognitive behavioural therapy for insomnia (CBT‐I) is an evidence‐based treatment, which targets factors that perpetuate insomnia over time. Using a format developed by Brown and colleagues (1999) of offering self‐referral psycho‐educational workshops for the community, one‐day CBT‐I workshops were run on a routine basis, throughout 2007, for the general public. These intensive workshop days were led by two clinical/counselling psychologists, and attracted a large number of self‐referrals. Participants completed a battery of measures at the introductory and follow up phases of the workshop programme including measures of insomnia, anxiety and depression. Of the 60 people who self‐referred, the large majority were women, 58% had clinical insomnia as indicated by the Insomnia Severity Index (ISI) and 75% had clinical levels of depression as measured by the Beck Depression Inventory (BDI; scores over 10). At the follow‐up stage, there were significant improvements on all measures, and there was a high degree of participant satisfaction with the workshops. Such large‐scale interventions offer an important, potentially cost‐effective means of disseminating evidence‐based psychological interventions to large numbers of people.

This study investigates how employees' experience of suffering from insomnia might reduce the likelihood that they perform creative activities, as well as how this negative relationship might be buffered by employees' access to resources at three levels: an individual resource (affective commitment), a relational resource (knowledge sharing with peers) and an organizational resource (climate of organizational forgiveness).

Quantitative data came from a survey of employees in the banking sector.

Insomnia reduces creativity, but this effect is weaker when employees feel a strong emotional bond to their organization, openly share knowledge with colleagues and believe that their organization forgives errors.

The limitations of this research include its relatively narrow scope by focusing on one personal stressor only, its cross-sectional design, its reliance on subjective measures of insomnia and creativity and its single-industry, single-country design.

The findings indicate different, specific ways in which human resource managers can overcome the challenges associated with sleep-deprived employees who avoid productive work behaviors, including creativity.

This study adds to extant scholarship by specifying how employees' persistent sleep deprivation might steer them away from undertaking creative behaviors, with a particular focus on how several pertinent resources buffer this process.

Posttraumatic stress disorder (PTSD), an anxiety disorder with lifetime prevalence of 7.8%, is characterized by symptoms that develop following exposure to traumatic life events and that cause an immediate experience of intense fear, helplessness or horror. PTSD is marked by recurrent nightmares typified by the recall of intrusive experiences and by extended disturbance throughout sleep. Individuals with PTSD respond poorly to drug treatments for insomnia. The disadvantages of drug treatment for insomnia underline the importance of non-pharmacological alternatives. Thus, the present study had three aims: first, to compare the efficiency of two relaxation techniques (muscular relaxation and progressive music relaxation) in alleviating insomnia among individuals with PTSD using both objective and subjective measures of sleep quality; second, to examine whether these two techniques have different effects on psychological indicators of PTSD, such as depression and anxiety; and finally, to examine how initial PTSD symptom severity and baseline emotional measures are related to the efficiency of these two relaxation methods. Thirteen PTSD patients with no other major psychiatric or neurological disorders participated in the study. The study comprised one seven-day running-in, no-treatment period, followed by two seven-day experimental periods. The treatments constituted either music relaxation or muscle relaxation techniques at desired bedtime. These treatments were randomly assigned. During each of these three experimental periods, subjects' sleep was continuously monitored with a wrist actigraph (Ambulatory Monitoring, Inc.), and subjects were asked to fill out several questionnaires concerned with a wide spectrum of issues, such as sleep, depression, and anxiety. Analyses revealed a significant increase in objective and subjective sleep efficiency and a significant reduction in depression level following music relaxation. Moreover, following music relaxation, a highly significant negative correlation was found between improvement in objective sleep efficiency and reduction in depression scale. The study‘s findings provide evidence that music relaxation at bedtime can be used as treatment for insomnia among individuals with PTSD.

As technology becomes more widely accessible, there is a growing concern about internet gaming disorder (IGD) around the world. The aim of this study is to evaluate the prevalence of IGD and also assess the effects of depression, anxiety, stress and insomnia levels on the IGD of youths in Bangladesh.

A cross-sectional quantitative study design was used to collect data from the youths of different locations in Bangladesh between October 21, 2023 and January 15, 2024. A total of 501 samples were collected using the convenience sampling technique. The following measurement scales were Internet Gaming Disorder Scale short form, depression, anxiety and stress scales and insomnia severity index, which were used to assess scores for IGD, psychological distress and insomnia, respectively.

The study found that the prevalence of IGD was 9.8%. IGD was shown to be significantly associated with depression, anxiety and stress. Aside from that, IGD and insomnia had a significant association, as did a friendly family environment.

The generalizability of the results could be improved by conducting additional studies with a more diverse sample, such as the general population or a different age group.

The study will help the government reduce the prevalence of IGD, improving the mental and physical health of youth.

No research has been conducted on youth and different professions in Bangladesh. There has also been very little research on the prevalence of gaming addiction and mental health.
