Purpose: Even though a number of studies have suggested that appropriate measuring instruments of family stress for working women have to be developed, the validity and reliability of the instruments used have not been consistently examined. The purpose of the present study was to develop a sensitive instrument to measure family stress for married working women, and to test the validity and reliability of the instrument. Method: The items generated for this instrument were drawn from a comprehensive literature review Twenty four items were developed through evaluation by 10 experts and twenty one items were finally confirmed through item analysis. Psychometric testing was preformed and confirmed with a convenient sample of 240 women employed in the industrial sector. Result: Four factors evolved by factor analysis, which explained 50.5% of the total variance. The first factor 'Cooperation' explained 28.1%, 2nd factor 'Satisfaction with relationships' 10.6%, 3rd factor 'Democratic and comfortable environment' 6.3%, and 4th factor 'Disturbance of own living' 5.5%, Cronbach's coefficient of this instrument was 0.86. Conclusion: The study supports the validity and reliability of the instrument.

Purpose: This study translated the developmental coordination disorder questionnaire'07 (DCDQ'07) into Korean and investigated the psychometric properties of the Korean DCDQ (DCDQ-K) using validation processes. Methods: The subjects were 300 parents with typically developing children aged 5-15 years (162 girls and 138 boys, mean age 9.24 years, SD 2.59) across the country. To develop the Korean DCDQ, a forward-backward-original author feedback-panel meeting-pilot study with parents was done. The internal consistency, test-retest reliability performed two weeks apart, content validity, discriminative validity, convergent validity, and constructive validity were examined with the pre-version of the DCDQ-K. Results: Approximately 15.33% of the subjects were probably shown DCD using DCDQ-K. Significant differences in age and province were observed in the DCDQ-K total score. The reliabilities and validities were good in the DCDQ-K. Conclusion: The DCDQ-K is a reasonable screening tool for DCD children.

Objectives Risk taking has been implicated in the development of various psychiatric disorders. Previous studies have indicated that risk taking behavior is associated with high levels of impulsiveness. Risk taking entail uncertain situation that outcome probability is unknown. This study tested impulsivity, intolerance of uncertainty and risk taking behavior. Methods A total of 73 participants completed a test battery comprised of the UPPS-P scale as a psychometric measurement of five dimensions of impulsivity, Intolerance of Uncertainty Scale, and Balloon Analog Risk Task (BART) as a behavioral measure of risk taking. The Pearson correlation analysis was used. Results The sensation seeking factor was positively correlated with BART measure (r = 0.27, p = 0.02). Specifically, the relationship between sensation seeking and BART was significant in females. Conclusions Among the five factors of UPPS-P, only the sensation seeking factor predicts risk taking propensity.

The purpose of this study was to verify the reliability and validity of the Job Meaning Scale for Nutrition Teachers (JMS-NT). The JMS-NT, the Nutrition Teacher Job Satisfaction Scale (NTJSS), and the Meaning in Life Questionnaire (MLQ) were administered to 180 nutrition teachers (female: 180, male: 0). The results showed that the JMS-NT had a three-factor structure in exploratory factor analysis. In addition, the test-retest reliability for all three factors of the JMS-NT was in the range of 0.69 to 0.85, and the internal consistency was in the range of 0.92 to 0.94, showing that they met the standards. The results of conducting Pearson correlation analyses between the JMS-NT and validity indicators such as the NTJSS and the MLQ were statistically significant, confirming the criterion validity of the scale. The above results show that the JMS-NT is a reliable and valid tool to measure the three factors of the job meaning of the nutrition teachers. Finally, the theoretical and practical significance, limitations, and future research tasks of the study were discussed.

The purpose of this study is to measure the validity and reliability of the Korean version of the self-efficacy for restorative care activity (K-SERCA) scale and the outcome expectations for restorative care activity (K-OERCA) scale. Psychometric testing was given to 187 nurses who have worked in 69 long-term care facilities in South Korea via post service and personal visit. Data were collected via structured-questionnaire and analyzed using SPSS/WIN 21.0 and AMOS 22.0. Content, construct validity using confirmatory factor analysis (CFA), criterion validity and internal consistency reliability were conducted. The K-SERCA scale had factor loading of the 10 items ranged from .74 to .87, and was validated by confirmatory factor analysis (CFI=.96, NFI=.94, RMSEA=.10). The K-SERCA scale was also a significantly positive correlation with 'Job satisfaction' (r=.32, p<.001). There was a reliable internal consistency with a Cronbach's ${\alpha}=.94$. The K-OERCA scale had factor loading of the 9 items ranging from .38 to .95, and was validated by confirmatory factor analysis (CFI=.98, NFI=.96, RMSEA=.09). The K-OERCA scale was also a positive correlation with 'Knowledge (r=.26, p<.001)', and 'Job satisfaction (r=.30, p<.001)'. There was a reliable internal consistency with a Cronbach's ${\alpha}=.89$. The results demonstrate that the K-SERCA and K-OERCA scales had satisfactory validity and reliability to measure self-efficacy and outcome expectations for restorative care activities among nurses who have worked in long-term care facilities in South Korea.

Background: Healthcare workers' practices regarding hepatitis B have an important effect on the control of this problem in workplaces. Methods: A questionnaire-based cross-sectional study was used to investigate the role of knowledge, cues to action, and risk perceptions as predictors of preventive behavioral intentions for hepatitis B among healthcare works in Broujen, Iran (n = 150). History of hepatitis B vaccination, hepatitis B surface antigen test, and demographic characteristics were investigated. The psychometric properties of the questionnaire were established. Results: Those who had a history of hepatitis B surface antigen test had a statistically significant higher level of risk perceptions ($30.89{\pm}4.08$ vs. $28.41{\pm}3.93$, p < 0.01) and preventive behavioral intentions ($5.05{\pm}1.43$ vs. $4.45{\pm}1.29$, p < 0.01). The mean score of cues to action was significantly correlated with age and work history (r = 0.20, p = 0.02 and r = 0.19, p = 0.02). Preventive behavioral intentions were significantly correlated with cues to action and risk perceptions but not with knowledge level. Cognitional factors were responsible for a 17% change in observed variance of preventive behavioral intentions, which was statistically significant. Conclusion: Risk perceptions were the most important determinant of preventive behavioral intentions for hepatitis B among health personnel; thus, emphasizing risk perceptions is recommended in educational programs aimed at increasing health personnel's practices regarding hepatitis B.

Objectives: Family caregivers (FCs) are often the primary source of social and emotional support for cancer patients and play a major role in how well they manage their illness. The aim of this study was to create an Turkish version of the Quality of Life - Family Version (QOL-FV) and to evaluate its psychometric properties in a sample of FCs of cancer patients. Materials and Methods: This study was carried out with the FCs of 218 patients with cancer. Data were collected with a Demographic Questionnaire and the QOL-FV and The Multidimentional Scale of Perceived Social Support (MSPSS). The QOL-FV was developed by Ferrell and Grant and is composed of 4 subdimensions. Linguistic validity, translation, back translation, and content validity were tested with expert opinions. Test-retest reliability, and internal consistency reliability were assessed. Construct validity was tested by factor analysis and with the scale of the MSPSS. Results: The family caregivers were between the ages of 46-56 (32.6%), a great number of them being male (52.8%). The scale is made up of four subdimensions. The result of the test-retest analysis of this scale was calculated as r:0.86. As a result of the reliability analysis, six items were eliminated from the scale, factor analyses were fulfilled according to varimax transformation through the method of principal components. Four new subdimensions were restrustured at the end of the analysis. The scale of Cronbach ${\alpha}$ coefficient was calculated as 0.90. Concurrent validity showed low correlations with the MSPSS (r=0.29). Conclusions: The QOL-FV, adapted into Turkish, was found to have sufficient reliability and validity.

Objectives: The Child Report of Post-traumatic Symptoms (CROPS) and the Parent Report of Post-traumatic Symptoms (PROPS) are screening measures for post-traumatic symptoms in children. The present study aimed to investigate the reliability and validity of the Korean versions of the CROPS and the PROPS. Methods: The Korean versions of the CROPS and the PROPS were administered to a sample of 304 children aged 6 to 15 years old. The internal reliability, test-retest reliability, factorial validity, predictive validity and concurrent validity were evaluated. Results: The reliability of the CROPS and the PROPS was shown to have excellent internal consistency and test-retest correlation. The single factor structure of the PROPS was good and that of the CROPS was borderline acceptable according to confirmatory factor analysis. Other validity measures such as the predictive validity and concurrent validity were also shown to be satisfactory. Conclusion: This study demonstrated that the Korean versions of the CROPS and the PROPS were reliable measures with satisfactory psychometric qualities. Because it takes less than 5 minutes to fill out the CROPS and the PROPS, respectively they can be quick and easy screening scales for assessing post-traumatic symptoms in Korean children.

Ankylosing spondylitis(AS) is one of the most common forms of chronic arthritis causing pain and progressive disability. The purposes of this study were 1) to develop an offline educational program and online educational program for the patients with ankylosing spondylitis; and 2) to test the effectiveness of each program in terms of changes in ankylosing spondylitis self-efficacy, exercise continuity disease activity, physical functioning, and depression. The convenient samples for three groups were selected acceding to the inclusion criteria. Online education group consists of 7 patients, and 14 patients were included for the offline group, while 12 patients were assigned to the control group. Outcomes variables included self efficacy, exercise continuity, disease activity, physical function, and depression and the reliability of each measure was ranged from .88 to .95 in the present study. The offline educational program demonstrated positive effects on self-efficacy, exercise continuity, disease activity, and depression, whereas the online educational program on exercise continuity, disease activity, and depression. The self-efficacy was showed positive effect only in the offline educational program, whereas physical functioning did not improve in both intervention groups. These partial improvements may be due to the small sample size and the methods of online education program. In conclusion, the effectiveness of the offline and online educational programs was partially supported in the present study. For the improvement of these programs, the further study would be necessary to apply this kind of intervention program with larger sample and to test the psychometric of the newly development tools.

Background: Measuring effects of cancer on family caregivers is important to develop methods which can improve their quality of life (QOL). Nevertheless, up to now, only a few tools have been developed to be used in this group. Among those, the Caregiver Quality of Life Index-Cancer Scale (CQOLC) has met minimum psychometric criteria in different populations in spite of conflicting results. The present study was conducted to evaluate reliability and validity of CQOLC among Turkish cancer family caregivers. Materials and Methods: The CQOLC was administered to 120 caregivers, along with Beck Depression Inventory (BDI), Medical Outcomes Study MOS 36- Item Short Form Health Survey (SF-36), State-Trait Anxiety Inventory (STAI), and Multidimensional Scale of Perceived Social Support (MSPSS). Internal consistency and test-retest stability were used to investigate reliability. Construct validity was examined by using known group method, convergent, and divergent validity. For the known group method, we hypothesized that CQOLC scores would differ between depressed and non-depressed subjects. We investigated convergent validity by correlating scores for CQOLC with scores for other similar measures including SF-36 and STAI. The MSPSS was completed at the same time as CQOLC to provide divergent validity. Results: The values for internal consistency and test-retest correlation were 0.88 and 0.96, respectively. The CQOLC discriminated those who were depressed from those who were not. Convergent validity supported strong correlations between CQOLC scores and two main component scores (PCS, MCS) in SF-36 although there was a weak correlation between CQOLC and STAI scores. Regarding divergent validity, the correlation between CQOLC and MSPSS was in the low range, as expected. Conclusions: The Turkish CQOLC is a reliable and valid tool and it can be utilized to determine QOL of family caregivers.
