Relationships Among Social Support, Professional Empowerment, and Nursing Career Development of Male Nurses A Cross-Sectional Analysis

The purpose of this study is to explore the relationships among social support, professional empowerment, and nursing career development and to identify the significant factors that affect nursing career development among male nurses. A cross-sectional survey design was used with 314 male nurses in Taiwan. Social support and professional empowerment were significantly and positively correlated with nursing career development among male nurses. Social support, professional empowerment, salary, type of institution, type of clinical level, and nursing discipline were identified as factors that significantly influenced nursing career development. Together, they accounted for 55.9% of the total variation. Professional empowerment was the most critical predictor of nursing career development and accounted for 47.7% of the variation. Nursing managers should follow male nurses’ empowerment with interest and specifically address professional empowerment to promote male nurses’ career development.

The Influence of Personality Traits and Social Support on Male Nursing Student Life Stress: A Cross-Sectional Research Design

Background: Understanding how male nursing students alleviate life stress during their academic career is conducive to their development as successful nursing professionals. Purpose: This study was designed to understand the personality traits, social support, and life stresses of male nursing students. The respective influences of personality traits and social support on life stress were also explored. Methods: The study used a cross-sectional research design. A college in central Taiwan was targeted as the site for data collection. A total of 158 questionnaires were dispatched, with 145 valid copies returned (valid response rate = 91.7%). Structured questionnaires were designed to collect data on participant demographics, personality traits, social support, and life stress. Statistical methods such as descriptive statistics, one-way analysis of variance, and multiple regression analysis were applied to data analysis. Results: Major findings of this study revealed that (a) in general, the personality traits, social support, and life stress of male nursing students scored in the medium to high range. Participants reported encountering more stress from learning and life goals than from interpersonal stress. (b) Male nursing student demographic variables (e.g., parent [father and mother considered separately] education level) and the personality traits of conscientiousness and family support, respectively, were found to impact significantly on participant life stress perceptions. And (c) the only significant predictors of life stress were support from family and education level of participant fathers and mothers, accounting for about 23.7% of variability. Conclusions and Implications for Practice: It is suggested that nursing students in each year of their academic career should be exposed to courses geared to reduce the life stress perceptions (especially in the areas of learning and career development) of male nursing students. Increased family support is an effective way to decrease male nursing student life stress. This study could be a reference for the design and application of strategies to reduce the perceived life stress of male nursing students.

The Potential for Mindfulness-Based Intervention in Workplace Mental Health Promotion: Results of a Randomized Controlled Trial.

Objectives This study aims to intensively evaluate the effectiveness of mindfulness-based intervention (MBI) on mental illness risks (including psychological distress, prolonged fatigue, and perceived stress) and job strain (job control and job demands) for employees with poor mental health. Methods A longitudinal research design was adopted. In total, 144 participants were randomized to the intervention group or the control group. The intervention group participated in MBI for eight weeks. Measurements were collected for both groups at five time points: at pre-intervention (T1), at mid-intervention (T2), at the completion of intervention (T3), four weeks after intervention (T4), and eight weeks after intervention (T5). Data were analyzed according to the intention-to-treat principle. A linear mixed model with two levels was employed to analyze the repeated measurement data. Results Compared with the control group, the intercepts (means at T3) for the intervention group were significantly lower on psychological distress, prolonged fatigue, and perceived stress when MBI was completed. Even with the demographic variables controlled, the positive effects remained. For growth rates of prolonged fatigue and perceived stress, participants in the intervention group showed a steeper decrease than did the participants in the control group. Regarding job strain, although the intercept (mean at T3) of job demands showed a significant decline when BMI was completed, the significance disappeared when the demographic variables were controlled. Moreover, the other results for job control and job demands did not show promising findings. Conclusion As a workplace health promotion program, the MBI seems to have potential in improving mental illness risks for employees with poor mental health. However, there was insufficient evidence to support its effect on mitigating job strain. Further research on maintaining the positive effects on mental health for the long term and on developing innovative MBI to suit job strain are recommended.

Relationships among sexual self-concept, sexual risk cognition and sexual communication in adolescents: a structural equation model

AIM The purpose of this study was to test a model of sexual self-concept and sexual risk cognition affecting sexual communication in Taiwanese adolescents. BACKGROUND Parent-adolescent sexual communication has been shown to influence adolescent sexual behaviour. Self-concept is an important predictor of human behaviour, especially sexual behaviour. Few researchers have assessed sexual self-concept in adolescents, despite its clear relevance to understanding adolescent sexual behaviour. DESIGN A cross-sectional survey with convenience sampling was used in this study. METHOD In 2009, data were collected by questionnaire from 748 adolescent students at a junior college in Taiwan. RESULTS The results revealed that the postulated model fits the data from this study well. Sexual self-concept significantly predicts sexual risk cognition and sexual communication. Sexual risk cognition significantly predicts sexual communication and has an intervening effect on the relationship between sexual self-concept and sexual communication. CONCLUSIONS Sexual risk cognition is important in explaining sexuality in adolescents. Sexual self-concept has both direct and indirect effects on sexual communication. Our findings provide concrete directions for school educators in developing sexual health programmes to increase adolescent sexual self-concept and sexual communication with their parents. RELEVANCE TO CLINICAL PRACTICE Future sexual health programmes about sexual self-concept and sexual risk cognition must add for increasing adolescents sexual communication with their parents.

Attentional biases for betel nut cues in heavy and light chewers.

The betel nut (Areca catecu) is regarded by the World Health Organization as the fourth most prevalent human carcinogen. Our study aims to investigate whether habitual chewers show bias in their attention toward betel nut usage. In the current study, heavy and light betel nut chewers were instructed to respond to a probe presented immediately after either one of a pair of areca-related picture and non-areca-matched picture. The presentation durations of these pictures were manipulated to investigate attentional biases under awareness threshold (17 ms), in initial orienting (200 ms), and maintenance of attention (2,000 ms). Faster response to the probe replacing the areca-related picture, in comparison with a matched picture, indicated attentional bias. The results showed that neither group showed subliminal attentional biases. Further, heavy chewers, but not light chewers, exhibited supraliminal biases toward betel nut cues in initial orienting of attention and maintained attention. Moreover, attentional bias scores at 2,000 ms were also shown to be positively associated with betel nut craving and dependence. Implications of the current findings are thoroughly discussed in the article.

Lifestyle Factors and Metabolic Syndrome among Workers: The Role of Interactions between Smoking and Alcohol to Nutrition and Exercise

This study aimed to investigate (1) relations of smoking and alcohol to metabolic syndrome (MetS) and its components, with nutrition and exercise controlled; and (2) interactions between smoking/alcohol and nutrition/exercise on MetS. This cross-sectional study enrolled 4025 workers. Self-reported lifestyles, anthropometric values, blood pressure (BP), and biochemical determinations were obtained. Among males, smoking significantly increased the risk of low high-density lipoprotein cholesterol (HDL-C), high triglyceride, abdominal obesity (AO), and MetS. Additionally, smoking showed significant interaction effects with nutrition on high BP, AO, and MetS; after further analysis, nutrition did not decrease above-mentioned risks for smokers. However, there was no significant interaction of smoking with exercise on any metabolic parameter. Alcohol increased the risk of AO, but decreased low HDL-C. It also showed an interaction effect with exercise on AO; after further analysis, exercise decreased AO risk for drinkers. Among females, alcohol significantly decreased the risk of high fasting blood glucose, but did not show significant interaction with nutrition/exercise on any metabolic parameter. In conclusion, in males, smoking retained significant associations with MetS and its components, even considering benefits of nutrition; exercise kept predominance on lipid parameters regardless of smoking status. Alcohol showed inconsistencies on metabolic parameters for both genders.

Effects of Nutrition and Exercise Health Behaviors on Predicted Risk of Cardiovascular Disease among Workers with Different Body Mass Index Levels

Workplace health promotion programs should be tailored according to individual needs and efficient intervention. This study aimed to determine the effects of nutrition and exercise health behaviors on predicted risk for cardiovascular disease (CVD) when body mass index (BMI) is considered. In total, 3350 Taiwanese workers were included in this cross-sectional study. A self-reported questionnaire was used to measure their nutrition and exercise behaviors. Data on anthropometric values, biochemical blood determinations, and predicted CVD risk (using the Framingham risk score) were collected. In multiple regression analyses, the nutrition behavior score was independently and negatively associated with CVD risk. Exercise was not significantly associated with the risk. However, the interactive effect of exercise and BMI on CVD risk was evident. When stratified by BMI levels, associations between exercise and CVD risk were statistically significant for ideal weight and overweight subgroups. In conclusion, nutrition behavior plays an important role in predicting the CVD risk. Exercise behavior is also a significant predictor for ideal weight and overweight workers. Notably, for underweight or obese workers, maintaining health-promoting exercise seems insufficient to prevent the CVD. In order to improve workers’ cardiovascular health, more specific health-promoting strategies should be developed to suit the different BMI levels.

Sexual Cognitive Predictors of Sexual Communication in Junior College Adolescents: Medical Student Perspectives

Background: Further understanding the relationship between sexual cognition and sexual communication in adolescents may facilitate sexual health promotion in this population. Purpose: This study was designed to investigate associations between sexual cognitive variables and sexual communication in adolescents. Methods: This study used a cross-sectional research design with conventional sampling. Data were collected from one medical college in central Taiwan. A total of 900 questionnaires were dispatched, with 748 copies returned, giving a response rate of 83.1%. Structural questionnaires were designed to collect demographic data, sexual self-concept inventory, sexual risk cognition, sexual self-efficacy, and sexual communication scale. This study applied statistical methods, including descriptive statistics, Pearson product-moment correlation, and multiple regression analysis. Results: Major findings revealed that (a) adolescents talked about sexual activity and sexual issues with their parents at a moderate level (mean = 2.52, SD = 1.24), (b) all sexual cognitive variables (sexual self-concept, sexual risk cognitions, and sexual self-efficacy) correlated positively with sexual communication, and (c) predictors of sexual communication were supported by demographic data (having heterosexual friends, satisfaction with heterosexual friends, and duration of relationships with heterosexual friends) and sexual cognitive variables, which accounted for 62.0% of variance. Conclusions/Implications for Practice: Study results can contribute to the development of safe sexual health programs and improve healthcare provider knowledge of sexual communication among adolescents. More sexual communication between adolescents and their parents is encouraged. Moreover, sexual health programs must give increased focus on the issue of adolescent sexual cognition to help encourage increased discussion between adolescents and their parents regarding sexual activity and issues.

Gender differences in psychological well-being: tests of factorial invariance

PurposeThis research investigated gender differences in the six factors of Li’s 18-item version of Ryff’s psychological well-being (PWB) scale by using factorial invariance procedures. This version improved on Ryff’s shorter PWB scale in regard to the reliability of each subscale.MethodsThe sample comprised 653 adult participants, specifically, 271 men and 382 women. Factorial invariance tests were conducted using multigroup confirmatory factor analysis.ResultsThe results showed that the Li’s version of Ryff’s PWB scale has configural invariance, factor loading invariance, intercept invariance, partial invariance of factor variances and covariances, partial invariance of latent means, and partial invariance of error variances. According to latent means, women had significantly less autonomy (AU) and more environmental mastery (EM) than men did. Moreover, based on interfactor correlations, the correlation of EM and self-acceptance was higher for men than for women, and the correlation of positive relationswith others and AU was lower for men than for women.ConclusionsGender differences in PWB can be found at the subscale levels of Li’s version, which exhibits metric and scalar invariance.

Relationships between different types of physical activity and metabolic syndrome among Taiwanese workers

This study aimed to investigate the relationships between different types of physical activity (PA) and metabolic syndrome (MetS). In this cross-sectional study, 3,296 Taiwanese workers were enrolled. A self-reported questionnaire was used to assess nutritional health behavior and PA levels related to occupation, leisure time, and commuting. Anthropometric measures, blood pressure and biochemical determinations of the blood were also obtained. Multiple logistic regression was used to evaluate the adjusted odds ratios (ORs) and 95% confidence intervals (CI) of MetS and its components associated with different types of PA. The prevalence of MetS was 16.6% in workers. Compared with a low level of leisure-time PA, a high level of leisure-time PA showed a significantly lower risk of high triglycerides (OR 0.73, 95% CI 0.61–0.87) and MetS (OR 0.76, 95% CI 0.62–0.95). Compared with a low level of occupational PA, a high level of occupational PA represented a significantly lower risk of both abdominal adiposity (OR 0.64, 95% CI 0.49–0.84) and high triglycerides (OR 0.71, 95% CI 0.55–0.90). However, commuting PA levels were not significantly associated with MetS and its components. In conclusion, occupational PA as well as leisure-time PA could be important for the prevention of MetS.
