The effect of shift rotation on employee cortisol profile, sleep quality, fatigue, and attention level: A systematic review

Background: Disrupted circadian rhythm, especially working night duty together with irregular sleep patterns, sleep deprivation, and fatigue, creates an occupational health risk associated with diminished vigilance and work performance. Purpose: This study reviewed the effect of shift rotations on employee cortisol profile, sleep quality, fatigue, and attention level. Methods: Researchers conducted a systematic review of relevant articles published between 1996 and 2008 that were listed on the following databases: SCOPUS, OVID, Blackwell Science, EBSCO Host, PsycINFO, Cochrane Controlled Trials Register, and CEPS. A total of 28 articles were included in the review. Results: Previous research into the effects of shift work on cortisol profiles, sleep quality, fatigue, and attention used data assessed at evidence Levels II to IV. Our systematic review confirmed a conflict between sleep-wake cycle and light-dark cycle in night work. Consequences of circadian rhythm disturbance include disruption of sleep, decreased vigilance, general feeling of malaise, and decreased mental efficiency. Shift workers who sleep during the day (day sleepers) experience cortisol secretion increases, which diminish the healing power of sleep and enjoy 1 to 4 hours less sleep on average than night sleepers. Sleep debt accumulation results in chronic fatigue. Prolonged fatigue and inadequate recovery result in decreased work performance and more incidents. Rotation from day shift to night shift and its effect on shift workers was a special focus of the articles retained for review. Conclusions: Disturbed circadian rhythm in humans has been associated with a variety of mental and physical disorders and may negatively impact on work safety, performance, and productivity.

The Effects of a Support Group on Dementia Caregivers’ Burden and Depression

Objective: The aim of the study is to investigate the effects of a support group on depression levels and burden among dementia caregivers in Taiwan. Method: An experimental, pre-intervention postintervention control group design was used in this study. The experimental group received intervention consisting of a 12-week support group for dementia caregivers. A total of 85 subjects were evaluated before intervention, after intervention, and at 1-month follow-up. Results: (a) The depression level of participants in the experimental group was significantly decreased after the intervention and at 1-month follow-up. (b) There was no significant difference in caregiver’s burden after the support group intervention and 1-month follow-up. Discussion: The improvement in dementia caregivers’ depression levels shows that the support group was effective for reducing caregivers’ depression although not effective for relieving their burden of care.

A Comparison of the Effects of Fixed- and Rotating-Shift Schedules on Nursing Staff Attention Levels A Randomized Trial

Purpose: Sleep deficit affects neurobehavioral functioning, reduces attention and cognitive function, and negatively impacts occupational safety. This study investigated selective attention levels of nursing staff on different shifts. Methods: Using a prospective, randomized parallel group study, selective attention was measured using the d2 test in 62 nursing staff in a medical center in Taiwan. Findings: There were significant differences in selective attention indicators (E%) between the fixed-day-shift group (control group) and rotating-shift group (experimental group): The percentage of errors (E%) for night-shift workers in the rotating-shift group was higher than that of fixed-day-shift workers, while the total number of items scanned minus error (TN − E) and concentration performance (CP) scores were higher for fixed-day-shift workers. Within the experimental group, the error rate on night shift was 0.44 times more than that on day shift and .62 times more than on evening shift; the TN-E on night shift was 38.99 items less than that on day shift, and the CP was 27.68 items less on night shift than on day shift; indicating that staff on the night shift demonstrated poorer speed and accuracy on the overall test than did the staff on day shifts. Conclusions: Inadequate sleep and a state of somnolence adversely affected the attention and operation speed of work among night-shift workers. More than 2 days off is suggested when shifting from the night shift to other shifts to provide adequate time for circadian rhythms to adjust.

The effect of music therapy on hospitalized psychiatric patients' anxiety, finger temperature, and electroencephalography: A randomized clinical trial

Purpose: This study aimed to explore the effectiveness of music therapy in reducing anxiety in hospitalized psychiatric patients. Methodology: The authors used a randomized clinical trial design and randomly allocated the 24 enrolled participants to the experimental or the control group. Patients in the experimental group received music therapy in a therapy room at a set time for 30 min each morning for 11 days. The authors administered the Beck Anxiety Inventory (BAI) and measured skin temperature and brain waves to determine anxiety level before, during, and after music therapy. Results: Experimental group participants had lower scores on the BAI than control participants, after the music therapy (z = −2.0, p < .05) and at 1-week follow-up (z = −2.2, p < .05), indicating that they were experiencing significantly less anxiety. The mean BAI anxiety score fell in the experimental group from 23.9 (SD = 9.9) at baseline to 13.9 (SD = 8.8), after music therapy, and 12.7. (SD = 10.5) at follow-up. The experimental group demonstrated a significant elevation in the average alpha electroencephalographic (EEG) percentage (from 38.1% to 46.7%) and a reduction in the average beta EEG percentage (from 61.9% to 53.4%) after the music therapy. After adjusting for change in patient finger temperature on the first day, mean change in finger temperature did not differ significantly between the experimental and control groups. Conclusions: Music therapy can relieve anxiety in hospitalized psychiatric patients and help them achieve a state of relaxation.

High Risk Sexual Behaviors for HIV among the In-School Youth in Swaziland: A Structural Equation Modeling Approach

Background Global efforts in response to the increased prevalence of the human immunodeficiency virus (HIV) are mainly aimed at reducing high risk sexual behaviors among young people. However, knowledge regarding intentions of young people to engage in protective sexual behaviors is still lacking in many countries around the world, especially in Sub-Saharan Africa where prevalence of human immunodeficiency virus is the highest. The objective of this study was to test the theory of planned behavior (TPB) for predicting factors associated with protective sexual behaviors, including sexual abstinence and condom use, among in-school youths aged between 15 and 19 years in Swaziland. Methods This cross-sectional survey was conducted using a anonymous questionnaire. A two-stage stratified and cluster random sampling method was used. Approximately one hundred pupils from each of four schools agreed to participate in the study, providing a total sample size of 403 pupils of which 369 were ultimately included for data analysis. The response rate was 98%. Structural equation modeling was used to analyse hypothesized paths. Results The TPB model used in this study was effective in predicting protective sexual behavior among Swazi in-school youths, as shown by model fit indices. All hypothesized constructs significantly predicted intentions for abstinence and condom use, except perceived abstinence controls. Subjective norms were the strongest predictors of intention for premarital sexual abstinence; however, perceived controls for condom use were the strongest predictors of intention for condom use. Conclusions Our findings support application of the model in predicting determinants of condom use and abstinence intentions among Swazi in-school youths.

Psychometric properties of the Chinese version of the Michigan Alcoholism Screening Test (MAST-C) for patients with alcoholism.

PURPOSE The aim of this study was to examine the psychometric properties of the Chinese version of the Michigan Alcoholism Screening Test (MAST-C). DESIGN & METHODS The sensitivity, specificity, and positive and negative predictive values for the MAST-C were examined in this study. FINDINGS The MAST-C had an internal consistency of 0.83 and a test-retest reliability of 0.89. It had a good content validity index of 0.92. Factor analysis identified four factors and the optimal cutoff point for the MAST-C was a score of 6/7, which yielded a sensitivity of 0.92, a specificity of 0.83, a positive predictive value of 0.92, and a negative predictive value of 0.83. PRACTICE IMPLICATIONS The MAST-C provides a fast, accurate, and sensitive method for clinically diagnosing alcoholism and clinical management.
