Purpose: This study was done to develop a cell phone addiction scale for Korean adolescents. Methods: The process included construction of a conceptual framework, generation of initial items, verification of content validity, selection of secondary items, preliminary study, and extraction of final items. The participants were 577 adolescents in two middle schools and three high schools. Item analysis, factor analysis, criterion related validity, and internal consistency were used to analyze the data. Results: Twenty items were selected for the final scale, and categorized into 3 factors explaining 55.45% of total variance. The factors were labeled as withdrawal/tolerance (7 items), life dysfunction (6 items), and compulsion/persistence (7 items). The scores for the scale were significantly correlated with self-control, impulsiveness, and cell phone use. Cronbach's alpha coefficient for the 20 items was .92. Scale scores identified students as cell phone addicted, heavy users, or average users. Conclusion: The above findings indicate that the cell phone addiction scale has good validity and reliability when used with Korean adolescents.

The present study investigatesthe reliability and validity of the innovation leadership scale. Originally the seven factors with 25 items were developed through literature review. With a sample of 177 employees in a large company, the results of factor analyses showed that the five-factor model with 14 items had a better fit to the data than the seven-factor model. These five factors were innovativeness pursue, problem solving, vision presentation, risk-taking, and showing initiative. All of these factors were significantly related to various criteria such as identification with the group, attachment to the group, organizational commitment, and supervisor satisfaction, confirming criterion-related validity of the scale. Results of multiple regression analyses showedthat risk taking and showing initiative were more important predictors in explaining criteria. Finally, implications and limitations were discussed. The findings suggest that the key factors of innovation leadership were initiative and risk-taking.

This study attempted to develop a valid and reliable instrument capable of measuring Korea midlife family resilience (The Korea Midlife Family Resilience Scale: KMFRS). An exploratory, non-experimental, cross-sectional, and quantitative design was used to develop and validate the KMFRS. A tentative factor structure of family resilience and an item pool of the scale were constructed through a comprehensive literature review and personal interview. The pilot study was conducted with 424 middle aged adults(40~59) to select items for a scale, resulting in a preliminary scale composed of 70 items. In the main study, the preliminary scale was administered to a national representative sample of 562 middle-aged Korean adults. The scale was filtered into 40 items by the item analysis and an exploratory factor analysis, resulting in 6 factors: Family Connectedness & Problem Solving, Family's Positive Perception of Adversity, Family's Economic Stability, Family Religion & Spirituality, Support of Extended Family, and Support of Friends & Neighbors. These 6 factors explained 61.82% of total variance. The findings of the current study indicate substantial support for the reliability and the validity of the KMFRS. Other challenges and suggestions for future research on family resilience scale are discussed.

Purpose: This study identified the reasons why tuberculosis (TB) patients withhold treatment in a bid to develop a assessment scale to select patients who needs nursing intervention in the early stage and decrease the risk of discontinuation of treatment. Sample: There were two samples. A sample of 191 patients with TB and having primary treatment and a second sample of N who were under re-treatment Methods: The study design included qualitative and quantitative methods. Qualitative data were collected from in-depth interviews of TB patients under re-treatment. The quantitative data were collected from 191 patients with TB under primary treatment. Results: Exploratory factor analysis revealed 11 factors explaining 69.6% of total variance. These factors were categorized into four subgroups. A depression scale was used to establish concurrent validity. The depression scale had a positive relationship (r=54) with the discontinuing of primary treatment. The internal consistency reliability for the four subgroups was over .84. The confidence coefficient was Cronbach's ${\alpha}$ .95. The final scale was a self-reported four Likert scale including 50 items. Conclusion: Reliability and validity was established for the scale and the scale can be used to examine the risk of treatment discontinuation for TB. The scale is an important resource for nursing interventions in identifying and treating high risk clients.

This study was conducted in order to develop a parenting behavior scale for parents of school-age children and to analyze the scale in terms of both reliability and validity. Data were collected from a sample of mothers of $1^{st}$ to 3rd grade students in four elementary schools located in Seoul. 778 mothers were administered a parenting behavior scale with 123 items, and 779 mothers were asked to verify the validity of the developed scale in which 45 items remained after a series of analyses. Data were analyzed by means of exploratory factor analysis, confirmatory factor analysis, and correlation analysis. The results of factor analysis identified five factors, Warmth, Reasoning, Intrusiveness, Coercion, and Neglect. The Cronbach's ${\alpha}$ of each factor demonstrated results of .82~.86, suggesting that the scale had adequate internal consistency. Concurrent validity was established by using correlations between mothers' parenting behaviors and children's social competence. Moreover, cross-validation was also verified for the five factors. Considering the reliability and validity of this scale, it can clearly serve as a useful tool for assessing parenting behavior which is closely related to child development.
