Sample size computations, which should be done at the planning stage of the study, are necessary for research to estimate a population parameter or test a hypothesis. For causal analysis of observational databases, sample size computations are generally not needed. Post-hoc power analyses, which are typically done with non-significant findings, should not be performed since reporting post-hoc power is nothing more than reporting p values differently. While sample size calculations are typically based on the tradition of significance testing, sample size calculations based on precision are feasible – if not preferred – alternatives. Sample size calculations depend on several factors such as the study objective, scale of measurement of the outcome variable, study design, and sampling design. Computing for sample size is not as straightforward as presented in textbooks but specific strategies may be resorted to in the face of challenges and constraints.

The concept of wellness has no single, universal acceptable definition. The situation gives room to developing and refining wellness both as a concept and an experience. This paper aimed to substantiate the concepts surrounding wellness within an illness experience. Beth Rodger's evolutionary method of concept analysis provided the organizing framework for this paper. The data source was a search of literature published from 2010-2016 on CINAHL, Medline, EBSCO, and Google scholar database. Trailing process is organized with particular focus on antecedents, attributes, and consequences.

The analysis found four attributes of wellness within illness namely: normalizing, independence, empowerment, and finding meaning strengthened by antecedents such as strong social support, motivation, constructive coping strategies, and cognitive reframing. Subsequently these may lead to adaptation to illness, being well, and living to illness. Looking at wellness and illness in dichotomy may lead to rote deftness thus expansion of the panorama of wellness within an illness experience may lead to more depth on the scientific understanding and varied application. Increased conceptual understanding and knowledge development on wellness will enable nurses in facilitating patient's adaptation during illness.

PURPOSE: The purpose of this study was to clarify the meaning and the nature of empowerment concept in some Iranian old people suffering from chronic diseases. METHODS: Concept analysis was undertaken according to the hybrid model, which consists of three phases: an initial theoretical phase, a fieldwork phase and a final analytical phase. After an extensive review of the literature in order to describe the characteristics and definition of the concept, a fieldwork phase followed in order to empirically elucidate the empowerment concept in the Iranian old people with chronic diseases. In the third phase, attributes of empowerment were extracted from the first and second phases. Purposive sampling was done for 13 participants consisted of 7 old people with chronic diseases, 3 family caregivers of elderly adult with chronic disease and 3 health care providers with experience of care with elderly patients with chronic disease. RESULTS: The review of literature in theoretical phase determined the attributes of the concept, including "active participation", "informed change", "knowledge to problem solve", "self-care responsibility", "presence of client competency", and "control of health or life". Fieldwork phase determined attributes such as "awareness promotion", "sense of control", "the development of personal abilities", "autonomy", and "coping". In the final analytical phase, the critical attributes of old people with chronic diseases were investigated. They included "social participation", "informed change", "awareness promotion to problem solve", "presence of client competency", and "control of health or life", "autonomy", "coping" and "the development of personal abilities". CONCLUSION: The concept analysis of empowerment showed some of the required conditions for the empowerment of older people with chronic diseases in nursing care, which have not been mentioned in the literature.

PURPOSE: The purpose of this study was to develop an empowerment program as a nursing intervention for mothers who care for a child with cerebral palsy at home and to determine the effects of the program on those mothers' self efficacy, coping behavior and burden. METHOD: An non-equivalent control group pretest-posttest design was used in this study. An Empowerment program was developed based on Dunst & Trivette's model. Using the program, the study was carried out from Dec. 13, 2003 to Jan. 17, 2004, mothers whose children, aged 1 to 6, were outpatients of the Dept. of Rehabilitation Medicine, at P University Hospital or registered at educational institutions for early disabled children. The experimental group of subjects were included in the new empowerment program which was held for two and half hours every week for 6 times. RESULTS: After treatment with the Empowerment Program, the experimental group was found to be significantly increased in score for self efficacy(t=4.55, p<.01), coping behavior(t=5.54, p<.001), objective burden(t=-3.96, p<.01) and subjective burden(t=-5.05, p<.01), in comparison to the control group. CONCLUSION: The Empowerment Program is very effective in increasing self efficacy and coping behavior of mothers having a child with cerebral palsy and decreasing their burden. Finally, this study would recommend that an empowerment program should be extended to community facilities such as public health offices and welfare centers.

OBJECTIVEThis study aimed to investigate the epidemiological characteristics and correlated factors of daily hassles among thermal power plant workers.

METHODSA mass screening of daily hassles and correlated factors was conducted on 498 workers from a thermal power plant in Zhengzhou in July, 2008. The questionnaires included Daily Hassles Questionnaires, Work Roles Questionnaires, Job Content Questionnaires (Chinese version), Effort-Reward Imbalance (Chinese version), Work Locus of Control Scale and Type A Behavior Scale, with content covering demographic characters and occupational stress correlated factors among subjects. The daily hassles was divided into lower level and higher level according to scores, and the epidemiological characteristics and correlated factors of daily hassles were analyzed.

RESULTSA total of 446 qualified questionnaires were obtained, effective response rate was 89.6% (446/498). For respondents, the age was (36.96 ± 6.49) years old, working length of the current job was (12.05 ± 7.54) years, the daily hassles scores was (9.01 ± 2.50), and the prevalence rate of the higher level of daily hassles was 34.1% (152/446). The multiple non-conditional logistic regression analysis showed 5-14 years' working length of current job (OR = 0.451, 95%CI: 0.225 - 0.904), average income > 3000 yuan(OR = 0.372, 95%CI: 0.202 - 0.684), reward (OR = 0.557, 95%CI: 0.325 - 0.954) and coping strategy (OR = 0.552, 95%CI: 0.330 - 0.925) were negatively correlated with daily hassles, and shift-work (OR = 1.887, 95%CI: 1.108 - 3.215), effort (OR = 2.053, 95%CI: 1.198 - 3.519), psychological demand (OR = 1.797, 95%CI: 1.049 - 3.078), negative affectivity (OR = 3.421, 95%CI: 2.065 - 5.668) were positively correlated with daily hassles.

CONCLUSIONThe prevalence rate of the higher level of daily hassles was considerable high for thermal power plant workers. Its negative correlated factors included 5 - 14 years' working length of the current job, average income > 3000 yuan, reward and coping strategy and its positive corelated factors included shift-work, effort, psychological demand and negative affectivity.

PURPOSE: This study was designed to identify burnout and factors influencing burnout in contingent nurses. METHODS: A cross-sectional design was conducted with a sample of 228 contingent nurses randomly selected from 25 general hospitals in Korea. The tools used for this study were scales measuring burnout (8 items), job stress (8 items), job satisfaction (9 items), self efficacy (9 items), organizational commitment (9 items), empowerment (9 items), autonomy (7 items) and social support (8 items). The data were analyzed using SPSS 15.0 employing Pearson correlation coefficients and multiple regression analysis. RESULTS: The mean score for burnout in contingent nurses was 3.05 points. Factors influencing burnout in contingent nurses were identified as job stress (beta=.40), satisfaction level with current ward (beta=-.25), organizational commitment (beta=-.21), job satisfaction (beta=-.19) and empowerment (beta=-.16). These factors explained 65.0% of burnout reported by contingent nurses. CONCLUSION: The results indicate which factors are major factors influencing burnout in contingent nurses in general hospitals. Therefore, these factors may serve as predictors of burnout in contingent nurses.

PURPOSE: The purpose of this study was to propose and test a predictive model that could explain and predict Korean nurses' turnover intentions. METHODS: A survey using a structured questionnaire was conducted with 445 nurses in Korea. Six instruments were used in this model. The data were analyzed using SPSS 15.0 and Amos 7.0 program. RESULTS: Based on the constructed model, organizational commitment, and burnout were found to have a significant direct effect on turnover intention of nurses. In addition, factors such as empowerment, job satisfaction, and organizational commitment were found to indirectly affect turnover intention of nurse. The final modified model yielded chi2=402.30, p<.001), chi2/df=2.94, RMSEA=0.07, RMR=0.03, GFI=0.90, AGF=0.87, NFI=0.88, CFI=0.92 and good fit indices. CONCLUSION: This structural equational model is a comprehensive theoretical model that explains the related factors and their relationship with turnover intention in Korean nurses. Findings from this study can be used to design appropriate strategies to further decrease the nurses' turnover intention in Korea.

OBJECTIVETo explore the relationship between job satisfaction and occupational stress in the workers of a thermal power plant.

METHODSThe cluster sampling method was used to investigate 875 workers in a thermal power plant. The job satisfaction, occupational stressors, strains, personalities, meeting strategy and social support were measured using occupational stress instruments, job content questionnaire and effort-reward imbalance questionnaire.

RESULTSThere were no significant differences of job satisfaction scores between different groups according to sex, educational level, marriage status, smoking and drinking (P > 0.05). But there were significant differences of job satisfaction scores between different age groups or between different service length groups (P < 0.01). The correlation analysis revealed that job satisfaction scores were related positively to responsibility for persons and things, promotion opportunity, job control, job stabilization, rewards, mental health, positive affectivity, self-esteem, superior support and coworker support scores (P < 0.05 or P < 0.01), negatively to role ambiguity and conflict, job future ambiguity, job demands, negative affectivity, depressive symptoms, patience, and mental locus of work control(P < 0.05 or P < 0.01). The results of variance analysis indicated that the job relationship, responsibility for persons and things, promotion opportunity, job control, job stabilization, reward, mental health, positive affectivity, self-esteem and buffer scores of the workers with high job satisfaction scores were significantly higher than those of workers with moderate and lower job satisfaction scores (P < 0.01), but the role ambiguity and conflict, job future ambiguity, job demands, and depressive symptoms scores and mental locus of work control of the workers with high job satisfaction scores were significantly lower than those of workers with moderate and lower job satisfaction scores (P < 0.05 or P < 0.01). The results of multivariate logistic regression analysis showed that the risk of job dissatisfaction for workers with low reward was about four times as high as that for workers with high reward (OR = 3.773), the risks of job dissatisfaction for workers with low social support and mental locus of external work control were about two times as high as that for workers with high social support or mental locus of internal work control (OR = 2.419 and 2.219, respectively). The daily life stress, low control strategy, low support strategy, low job control and negative affectivity were risk factors of job dissatisfaction (OR = 1.125 approximately 1.790), but the self-esteem and positive affectivity could reduce the risk of job dissatisfaction.

CONCLUSIONIncreasing the decision level, social support, meeting strategy and reward or decreasing the role conflict and ambiguity, demands and negative affectivity could improve worker's job satisfaction level.

PURPOSE: The purpose of this study was to determine effects of an empowerment education program (EEP) on internet games addiction, empowerment, and stress in middle school students. METHODS: The EEP used in this study was based on the Freire's Empowerment Education Model. The research design of this study was a non-equivalent control group pretest-posttest design for 48 middle school students, who were conveniently assigned to an experimental group or a control group. The data were collected from May 29 to June 19, 2005. Data were analyzed using SPSS/PC program with frequencies, chi-square-test, Fisher exact test, t-test, mean, standard deviation and ANCOVA. RESULTS: 1) The first hypothesis that, "the experimental group would have higher empowerment scores than the control group." was supported. 2) The second hypothesis that, "the experimental group would have lower internet games addiction scores than the control group." was supported. 3) The third hypothesis that, "the experimental group would have lower stress scores than the control group." was supported. CONCLUSION: We suggest, therefore, that the EEP should be used with adolescent to help them control their stress, internet games addiction and to increase their empowerment.

PURPOSE: This study aimed to evaluate the effects of an empowerment program on maternal stress, anxiety, depression and parenting confidence. METHODS: A total of 44 mothers of preterm infants were assigned into an experimental or a control group (n=22 each). The experimental group received the usual nursing care and 7 sessions of an empowerment program. The control group only received the usual care. The program was implemented from June to December, 2016 in the neonatal intensive care unit of K university-affiliated hospital in Daegu, Korea. The outcome variables measured were parental stress (PSS: NICU), anxiety (STAI), depression (CES-D) and parenting confidence. Data were analyzed using t-test or repeated measures ANOVA. RESULTS: Scores for both parental stress (t=3.07 p=.004) and depression (F=3.76, p=.26) were significantly lower in the experimental group than in the control group. However, there were no significant differences in anxiety between the groups (F=0.79, p=.505). Parenting confidence scores (F=9.05, p=.001) were significantly higher in the experimental group than in the control group. CONCLUSION: A maternal empowerment program can be an effective means of reducing parental stress and depression as well as enhancing parenting confidence, for mothers of preterm infants.
