Effects of positive psychological control intervention on sleep and psychology of officers and soldiers working at sea

BACKGROUND The working environment of submarine crews is also very special.They are in a closed,high-temperature,high-noise,high-vibration and narrow working and living space for a long time,and they suffer from physical discomfort caused by seasickness,which will affect the mental health of officers and soldiers.American psychologists have achieved positive results in psychological resilience training for officers and soldiers from the perspective of positive psychology.At present,there are few reports on the correlation between psychological resilience in the field of domestic research on submarine crew psychology,and it is necessary to conduct further research.METHODS A total of 121 soldiers working in a confined space of a large ship were randomly divided into an experimental group and a control group.The 50 soldiers in the experimental group were given a training course intervention,while the 71 soldiers in the control group did not receive any intervention measures.The Pittsburgh Sleep Quality Index,Psychological Resilience Scale,military Psycho-logical Stress Self-Assessment Questionnaire,and General Self-Efficacy Scale scores were compared before and 6 months after the intervention.RESULTS Under the positive psychological control intervention,except for sleep efficiency(P=0.05),the difference between the remaining dimensions of the Pittsburgh Sleep Quality Index scores and the total scores of the experimental group compared with the control group was statistically significant(P<0.05);the assessment of the psychological condition showed that,in addition to the Psychological Stress Self-assessment Questionnaire for Military Personnel scores(P=0.05),the scores of the Mental Toughness Scale(Dispositional Resilience Scale Resilience II)in the experimental group,General Self-Efficacy Scale scores were statistically significant(P<0.05)compared to pre-intervention.CONCLUSION Positive psychological intervention and control can improve the sleep state and psychological state of officers and soldiers working in confined space at sea.

Prevalence and associated factors of stress, anxiety and depression among emergency medical officers in Malaysian hospitals

BACKGROUND： Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian hospitals.METHODS： A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale. RESULTS： The highest prevalence was anxiety （28.6%） followed by depression （10.7%） and stress （7.9%）. Depression, anxiety and stress between seven hospitals were not significantly different （P〉0.05）. Male medical officers significantly experienced more anxiety symptoms than female medical officers （P=0.0022）, however depression and stress symptoms between male and female medical officers were not signi？ cantly different （P〉0.05）. Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals （P〉0.05）. CONCLUSION： The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers’ anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.

An Evaluation of Suicidality and Its Predictors in Police Officers in Lagos, Nigeria

Background: The many dangers and stressors associated with police work often place police officers at a great risk of a variety of mental health morbidity, including suicidality. The causation of suicidality is multi-dimensional, however, there are insufficient studies which have examined the burden and risk factors of suicidality in Nigerian police officers. Objective: To determine the prevalence and predictors of suicidality among police officers in Lagos, Nigeria. Methods: This was a cross-sectional study of 600 police officers who were selected using a non-probability sampling method. Questionnaires used were: Suicide Behaviour Questionnaire-Revised (SBQ-R), State-Trait Anxiety Inventory (STAI), and a Socio-Demographic Questionnaire. Results: Prevalence of suicidality was 14%, and the predictors of suicidality were: state anxiety (p 0.001), trait anxiety (p 0.001), substance use (p = 0.03), being unmarried (p = 0.03), and female gender (p = 0.02). Conclusion: Suicidality is prevalent among Nigerian police officers, with a higher risk in those who are vulnerable. The creation of government policies and infrastructure which promote mental health in police officers is necessary.

Powerful Chief Executive Officers and Firm Performance： Integrating Agency and Stewardship Theory

Do agency and stewardship behaviors coexist at firms, or does one dominate the other？ We use data from listed companies in China over the period 2007-2016 to show that powerful chief executive officers （CEOs） simultaneously incur self-interested agency costs while acting as stewards to benefit the firm. In balancing the push-and-pull forces of stewardship and agency behaviors, powerful CEOs in Chinese firms ultimately improve short-term and long-term firm performance. Our results have important implications for understanding how CEOs affect firms and how cultural factors can motivate CEOs to work in the interest of the firm.
