  • Background This article describes the development of the Myanmar Articulation, Resonation, Nasal Emission, and Nasal Turbulence test for children with cleft lip and palate (CLP), and evaluation of its validity and reliability. Methods It was created by three Thai researchers and a Burmese research assistant based on Burmese phonology. The content validity was evaluated by six Burmese language experts. All test items were divided into three groups: high-pressure oral consonants, low-pressure oral consonants, and nasal consonants. Results All items (58-word and 32-phrase/sentence) gave an excellent level of the expert agreement (item-level content validity indexes = 1.00). The target items were illustrated as color pictures. Each picture was clearly drawn and easy to identify. As a pilot study of face validity, all pictures were administered to 10 typical-developing children. The actual testing was assessed by 10 CLP children, and the developed test was analyzed through consultation of the Burmese teachers and interpreters from a speech camp. Testing scores for a total including three groups of target items were shown acceptable for internal consistency reliability (ranged from 0.4 to 0.88). Conclusion The constructed test is valid in terms of its content.

  • Purpose: The purpose of this study was to develop and evaluate breastfeeding effectiveness scale to measure effectiveness of breastfeeding for mothers in the early postpartum period. Methods: A conceptual framework was constructed from properties of effective breastfeeding (Yang and Seo, 2011), and item construction was derived from literature review and analysis of the data along with interviews with breastfeeding mothers. Content validity was tested by experts. Each item was scored on a five-point Likert scale. The preliminary questionnaire was administered to 248 breastfeeding mothers. Data were analyzed using item analysis, factor analysis, Pearson correlation coefficients, and Cronbach's ${\alpha}$. Results: From the factor analysis, 20 items in seven factors were derived. The factors were identified as mother's satisfaction, suckling, assurance of milk quantity, infant's satisfaction, latching on, infant's feeding desire, and breastfeeding positioning. The seven factors explained 65.1% of total variance, Cronbach's ${\alpha}$ of the total items was .83 and the factors ranged from .44 to .75. Conclusion: Results of this study suggest that breastfeeding effectiveness scale is a reliable and valid instrument to measure breastfeeding effectiveness of mothers in the early postpartum period.

  • Purpose: The purpose of this study was to develop and evaluate a coping scale for families of patients with schizophrenia (CSFPS). Methods: Item construction was derived from literature reviews and interviews with family members and psychiatric nurses. Content validity was tested by experts. Each item was scored on a four-point Likert scale. The preliminary questionnaire was administered to 188 family members of patients with schizophrenia. The data were analyzed using item analysis, factor analysis, Pearson correlation coefficients, and Cronbach's alpha. Results: From the factor analysis, 32 items in five factors were derived. The factors were named active coping strategies, avoidance coping strategies, hospital treatment-oriented coping strategies, emotional coping strategies, and suppressive coping strategies for problematic behaviors. The five factors explained 49.7% of the total variance, Cronbach's alpha of the total items was .83 and the factors ranged from .66 to .86. Conclusion: The results of this study suggest that CSFPS is a reliable and valid instrument to measure coping in families of patients with schizophrenia.

  • Severity and frequency of industrial accidents are typically used to assess the "absolute" risk associated with the industrial machines and devices ("items") which are subject to safety certification or self-declaration of conformity. However, the "relative" risk associated with a particular item can further be assessed based on unit severity and unit frequency where the total number of item in use is taken into account. This study first attempts to estimate the total number of each item in use which was recently selected for safety certification or self-declaration of conformity. The appropriateness of such selection is recapitulated based on the relative risk involved. Analysis results indicate that depending on items, the relative risk is differentiated from the absolute risk. Recent selection of items for safety certification or self-declaration of conformity is then revisited for its validity. The relative risk based on unit severity and unit frequency of industrial accidents, together with the absolute risk, may be used to further categorize items for safety certification or self-declaration of conformity in the future.

  • This study is intended to create a tool which can identify the concept of consumption life level and to develop a standardized scale to measure consumption life level. Based on it, the concept and perspective of consumption life level was formed and then the scale for measuring it was developed. To develop the scale, the scale was firstly formed by extracting questions through a literature survey, and verifying validity through experts' opinions. Then the final scale was developed by conducting a questionnaire survey for consumers. A preliminary 27-item scale was developed through a literature review. 1000 consumers responded to an online survey using the preliminary scale. This research was made with the intention of not only supplying academic data on the consumer's consumption life level but also understanding the consumer's basic behavior patterns. Then a series of tests: test-retest, item-to-total correlation, and Cronbach's reliability coefficient and factor analysis were conducted using the survey data and the final 20-item scale was constructed in the end. The consumer's consumption life level scale consisted of 4 factors.

  • The purpose of this study was to develop the Parent Satisfaction Scale(PSS) to measure the various components of satisfaction related to parenting. The subjects were 1210 parents(249 fathers and 961 mothers) selected nation widely from 7 cities and several rural area in Korea. the statistics used for data analysis were Fisher's Exact Test, Cramer's V, factor analysis multiple regression, Cronbach's α,and Pearson's correlation. To begin with eighty of 100-item scale were selected through the item analysis and from that 48 items were abstracted through the multiple regression analysis conducted to reduce the length of the scale. Results of factor analysis indicated that the PSS comprised of five factors: general satisfaction parent-child relationship spouse support parent's role conflict support of children. Reliabilities for the domains ranged from 79 to 91. To determine the construct validity of this instrument the Marital Satisfaction Scale and the Proverb about child rearing were administered. The two creterion measures showed significant relationships with the PSS. The final 48 items scale from the current analysis were considered to be critical steps in the development of this assessment device.

  • The purpose of this study was to validate New Ecological Paradigm(NEP) Scale for use with elementary school students in Korea, and to obtain evidences of validation for interpreting the scores on the instrument. Three pilot tests were taken to modify and 1,003 fifth and sixth grade students in elementary schools participated in this survey. To examine the reliability and validity of the NEP Scale for elementary school students in Korea, item analysis(mena, skewness, kurtosis, item-total correlation), internal consistency estimate, exploratory factor analysis, confirmatory factor analysis, and t-test were used. After analyzing their results, the authors suggest that a 2-dimensional(pro-NEP, anti-NEP) modified NEP Scale, with 15 items and revised wording, is appropriate for use with elementary school students in Korea.

  • The purpose of this study was to develop a reliable and valid instrument to assess Korean teachers' strategies for addressing challenging behaviors of preschoolers. The Teacher Strategy Questionnaire(TSQ) consisting of 34 items was developed with three theoretically driven factors(positive proactive, positive reactive, and negative reactive strategies). Participants were 238 preschool and daycare center teachers who responded to the TSQ. Validity and reliability of the TSQ were explored using Cronbach's $\alpha$, item analysis, and factor analyses. The reliability of the TSQ was relatively high, ranging from .74 to .85. No item needed to be eliminated. Among the three pre-structured factors of the TSQ, one positive proactive factor was identified as having two innate factors.

  • The purpose of this study was to validate the Child Behavior Checklist(CBCL) with a population of Korean children. Subjects were 415 mothers of fourth and sixth graders selected from five elementary schools in Seoul. The CBCL(Achenbach, 1991) and the Child Behavior Questionnaire(CBQ; Rutter et als., 1970) were used as a methodological instrument. Statistics used for data analysis were ${\chi}^2$, Cramer's V, factor analysis, Pearson's r, and Cronbach's ${\alpha}$. The major findings were that 102 items of the 107-item scale were found acceptable through the item discriminant method. Nine factors (anxious behavior, hyperactive behavior, immature behavior, delinquent behavior, aggressive behavior, withdrawn behavior, thought problems, somatic complaints, other problems) were extracted by factor analysis. The correlation between the CBCL and the CBQ was examined to test criterion-related validity, and the coefficient was significant (r=.78, p<.001). Finally, the internal consistency of the CBCL appeared to be at an acceptable level (Cronbach's ${\alpha}$=.83).
