  • The Early Life Problems Scale consisting of 5-point rating for each item was prepared from the results of a questionnaire of 163 items with two sub scales constructed on the basis of Diagnostic Classification: 0-3. Respondents were 361 parents with newborn to 3-year-old children (197 boys and 164 girls). Hypothetical constructs of mental and developmental problems were identified by exploratory factor analysis. The resulting 22 factors explained 58.5% and 72.9% of the common variance for scales I and II, respectively. The rotation procedure yielded 134 items of which 118 had factor loadings of more than .30. Face validity was obtained on the basis of 18 items. The coefficients of correlation between and within factors suggest that there are interrelationships. The reliability of total scales by Cronbach's Alpha was relatively high.

  • The purpose of this study is to establish a basis for assessing construct validity of measures used in organizational research. The classic Campbell and Fiske's(1959) criteria are found to be lacking in their assumptions, diagnostic information, and power. The inherent confounding of measurement error with systematic trait and method effects is a severe limitation for a proper interpretation of convergent and discriminant validity. The confirmatory factor analysis(CFA) approach overcomes most of the limitations found in Campbell and Fiske's(1959) method. However, the CFA approach confounds random error with unique variance specific to a measure. The second-order confirmatory factor analysis(SOCFA) was shown to harbor rather restrictive assumptions and is unlikely to be met in practice. The first-order, multiple-informant, multiple-item(FOMIMI) model is a viable option, but it may also be of limited use because of the large number measures.

  • This study aims to understand how consumers consume by presenting the concept of 'consumption style' and the meaning of consumption for modern consumers. As modern consumers cannot lead their daily lives without engaging in consumption, their daily lives are deeply related to consumption. However, we have not been largely interested in how we manage consumption. It is a fact that marketing-oriented studies are focused on consumers for the establishment of corporate activities and strategies until now. For the analysis of the research, SPSS for Windows and AMOS were used. In order to examine the general characteristics of the investigation object, the technical statistics of frequency, percentage, average and standard deviation were obtained. To develop the research item analysis, Cronbach's ${\alpha}$, exploratory factor analysis, confirmatory factor analysis and cluster analysis were conducted. Based on the meaning of consumption through the consideration of preceding studies, the consumption style was extracted with 4 economic, socio-cultural, psychological and ethical perspectives. Also, 4groups were classified according to the type of consumption style: professional consumers, practical consumers, indifferent consumers and emotional consumers.

  • This paper considers two modes of partially accelerated life tests for items having Weibull lifetime distributions. In a use-to-acclerated mode each item is first run at use condition and, if it does not fail for a specified time, then it is run at accelerated condition until a predetermined censoring time. In an accelerated-to-use mode each one is first run at accelerated condition and, if it does not fail for a specified time, then it is run at use condition. Maximum likelihood estimators of the parameters of the lifetime distribution at use condition, and the 'acceleration factor' are obtained. The stress change time for each mode is determined to minimize the asymptotic variance of the acceleration factor, and the two modes are compared. For selected values of the design parameters the optimum plans are obtained, and the effects of the incorrect pre-estimates of the design parameters are investigated. Minimizing the generalized asymptotic variance of the estimators of the model parameters is also considered as an optimality criterion.

  • This research empirically investigated the influence factors on the adoption of environmental management systems (EMS) in Korean manufacturing firms. In this study, the external factors (cause factors), the internal factors (facilitating factors) and the firm specific characteristics were integrally considered. In the factor analysis, the third item (regional society) of the external factors and the first item (environmental law) of government regulation were confounded with the items of the other factors. Thus, the confounded items were removed. In the second factor analysis, no items were replicated. The results of a multiple regression analysis showed that the influence factors such as government regulation, normative pressure, top management support, environmental strategy and employees' recognition, and ratio of large shareholders have a significant impact on the construction of EMS. However, the effects of the other firm specific characteristics were not statistically significant. We also examined whether both the number of environmental personnel and the allocation of environmental resources, which are directly related with the adoption of EMS, have a moderating impact on the relationships between other internal factors and the construction of EMS. With a subgroup analysis, the moderating roles of the number of environmental personnel were empirically confirmed. Through a multiple regression analysis, the direct effects of the external factors on the adoption or construction of the internal factors were demonstrated. The effects of government regulation, normative pressure and imitative pressure on the internal factors were significant and positive. Finally, in this study, the fact that the adoption of EMS can improve the environmental performance of a firm was also empirically found.

  • Purpose: To develop the stress coping behavior measurement scale(SCBMS) for the workers in manufacturing industry. Methods: Developing of SCBMS was based on job stress and psycho-social health status. Job stress and psycho-social health status were estimated by using the Karasek's job content questionnaire (JCQ) and the general health questionnaire (GHQ-28), and the general characteristics for subjects were estimated by self-reported questionnaire and interview. Result: The subjects were 456 male workers who had never been occupationally exposed to hazardous chemical and other materials, was mean age 31.27 years and mean work duration was 4.81 years. As a result of factor analysis for developed stress coping questionnaire, four factors were extracted such as inactive, active, health and emotional behavior from 15 question items of stress coping questionnaire. Fifteen items passed for item internal consistency (100% success rate) and item discriminant validity (100% success rate). Cronbach's alpha coefficient for each factor ranged from 0.56 to 0.77. The active behavior correlated positively with job demand of JCQ (r=0.12, p<0.05), but total GHQ-28 was negatively correlation (r=-0.24, p<0.01), respectively. Conclusion: These results demonstrated the reliability and validity of SCBMS. Thus, the results may prove to be a useful assessment tool in evaluating stress coping behavior.

  • Background: Patient safety is one of the key components of nursing care for cancer cases. Valid and reliable context-based instruments are necessary for accurate evaluation of patient safety in oncology units. The aim of the present study was to develop and evaluate the psychometric properties of the Patient Safety Violation Scale in medical oncology units in Iran. Materials and Methods: In this methodological study, a pool of 58 items was generated through reviewing the existing literature. The validity of the 58-item scale was assessed through calculating impact score, content validity ratio, and content validity index for its items as well as conducting exploratory factor analysis. The reliability of the scale was evaluated by assessing its internal consistency and testretest stability. Study sample consisted of 300 oncology nurses who were recruited from thirteen teaching hospitals affiliated to Tehran University of Medical Sciences, Tehran, Iran. Results: Sixteen items were excluded from the scale due to having low impact scores, content validity ratios, or content validity indices. In exploratory factor analysis, the remaining 42 items were loaded on five factors including patient fall, verification of patientidentity, harm during care delivery, delay in care delivery, and medication errors. These five factors explained 62% of the total variance. The Cronbach's alpha of the scale and the test-retest interclass correlation coefficient were equal to 0.933 and 0.92, respectively. Conclusions: The 42-item Patient Safety Violation Scale is a simple and short scale which has acceptable validity and reliability. Consequently, it can be used for assessing patient safety in clinical settings such as medical oncology units and for research projects.
