The purpose of this study was the investigation of theoretical and empirical relationships between Piagetian and psychometric assessments of intelligence. Specifically, the factor structure of Piagetian-type scales, the relationship between Piagetian scales and psychometric intelligence tests, and differences in the factor structure of Piagetian and psychometric assessments of intelligence were studied. The subjects of this stuby were 70 children (35 boys and 35 girls) in the 1st grade of an elementary school in Seoul The Piagetian-type scales and the K-WISC were administered individually, and the General Intelligence Test was administered to groups of children. Statistical analysis of the obtained data consisted of the SPSS Computer program including factor analysis and Pearson's product moment correlation coefficient. The Piagetian-type scales were found to consist of three factors, which accounted for 55 percent of the total common-factor variance. Factor-I was a factor indicating "conservation". Factor-II was a factor indicating "moral judgements". Factor-III was a factor indicating "classification and identity". Correlations between subtests of psychometric tests and Piagetian scales were relatively low or moderate. Relations between IQs assessed by the psychometric tests and Piagetian scales were also relativeyly low or moderate. Eight factors were extracted from the joint factor analysis of psychometric intelligence tests and Piagetian scales, and they accounted for 67 percent of the total common-factor variance. Factors-I, II, III, and V consisted of subtests of psychometric assessments, and Factors-IV, VI, VII and VIII were composed of Piagetian scales. Factor-I was a factor for "reasoning ability based upon language". Factor-II was a factor for "performance ability". Factor-III was a factor for "grouping ability". Factor-IV was a factor for "conservation". Factor-V was a factor indicating "symbol and language usage ability". Factor- VI was a factor indicating "moral judgments". Factor-VII was a factor indicating "length consevation". Factor-VIII was a factor indicating "classification and identity".

A survey of risk perception in South Korea was conducted in 2007 to evaluate relative riskiness of typical industrial and technological risks. This article summarizes the characteristics of risk perception using psychometric analyses. The survey with a sample size of 1,194 reviews the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, nuclear power generation, and newly-introduced risks. Six categories of risk identified by a factor analysis show that the level of perceived risk does not correspond to the statistical level. Psychometric analyses including voluntariness, severity, effect manifestation, exposure pattern, controllability, familiarity, benefit and necessity demonstrate that voluntary, familiar and immediate risks are perceived as less risky than involuntary, unfamiliar and delayed ones. Risk communication is critical in reducing the discrepance between objective and subjective level of risk. However, the amount of risk information does not always justify a successful risk communication. A safety policy, risk communication strategy in particular, should take into account diverse dimensions of risk reviewed by psychometric analyses in the study. Social policy toward safety can be improved by integrating policy, human, and social factors as well as technological advances.

Background: This study aimed to develop and assess the psychometric features of the Physical Activity at Workplace Questionnaire (PAWPQ) based on the Social Cognitive Theory (SCT) to evaluate employees' physical activity (PA) behaviors at the workplace. Methods: This psychometric cross-sectional study was conducted on 455 employees working in one of the gas refineries in Iran. The participants were selected using the proportional stratified sampling method in 2019. The data collection tools were a demographic information questionnaire, the short form of the International Physical Activity Questionnaire (IPAQ), and a questionnaire developed based on the SCT, whose psychometric features were confirmed in terms of validity and reliability. Data were analyzed using SPSS₂₂ and AMOS₂₀ software. Results: The first version of PAWPQ-SCT had 74 items. After evaluating content and face validity, nine items were removed. The results of the content validity index (0.98), content validity ratio (0.86), and impact score (3.62) were acceptable for the whole instrument. In exploratory factor analysis, after removing seven items-58-item final version of the scale-six factors could explain 73.54% of the total variance. The results of structural equation modeling showed the acceptable fit of the model into the data (RMSEA = 0.052, CFI = 0.917, NFI = 0.878, TLI = 0.905, IFI = 0.917, CMIN/DF = 2.818). Cronbach's alpha coefficient and Intraclass Correlation were 0.90 and 0.86, respectively. Conclusion: This study confirmed that the psychometric features of the 58-item final version of PAWPQSCT constructs were acceptable in a sample of Iranian employees. This questionnaire can be used as a valid and reliable tool to evaluate Iranian employees' PA behaviors and develop effective educational interventions for workers and managers.

Purpose: The purpose of this study was to develop and evaluate psychometric properties of the instrument, Resuscitation Self-Efficacy Scale for nurses. Methods: This was a methodological study for instrument development and psychometric testing. The initial item pool derived from literature review and experts resulted in 30 items linked to resuscitation self-efficacy. A convenience sample of 509 Korean nurses from eleven academic teaching hospitals participated in a survey to examine psychometric properties of the scale. To examine construct validity, exploratory factor analysis and known-group comparison were used. Cronbach's coefficient alpha was used to determine the scale's internal consistency reliability. Results: The final scale included 17 items with four-component structure termed 'Recognition', 'Debriefing and recording', 'Responding and rescuing', and 'Reporting'. These four factors accounted for 57.5% of the variance. Each subscale and the total scale demonstrated satisfactory internal consistency: .82; .88; .87; .83; and .91 respectively. Experienced nurses reported significantly higher self-efficacy mean scores in both total and subscales compared to new graduate nurses. Conclusion: The Resuscitation Self-Efficacy Scale for nurses yields reliable and valid results in appraising the level of resuscitation self-efficacy for Korean nurses. Further study is needed to test and refine the scale.

Objective: The purpose of this study was to develop and examine the psychometric properties of the Client Satisfaction Questionnaire on multicultural family support services. Methods: The Client Satisfaction Questionnaire was designed to address key elements of the client's satisfaction with the services (i.e., family education, gender equality education, human right education, and social integration education) provided for multicultural families. The nationwide data were collected from 5,335 clients who participated in family education, 4,582 clients who participated in gender equality education, 4,777 clients who participated in human right education, and 5,547 clients who participated in social integration education at the multicultural family support center. Results: In general, the psychometric properties of the Client Satisfaction Questionnaire were satisfactory. Specifically, social validity was supported by 13 professors and local multicultural service center professionals and construct validity was tested and confirmed using a series of exploratory and confirmatory factor analyses. The split-half reliability and internal consistency of the questionnaire were also highly acceptable. Conclusion: The sound psychometric properties of the Client Satisfaction Questionnaire indicates that the it can be a useful tool for evaluating client satisfaction with the services provided by multicultural family support centers.

Objectives: This case report examines the effects of traditional Korean medicine for unspecified tremor with xerostomia caused by psychometric drug intake. Methods: A patient who suffered from unspecified tremor with xerostomia caused by psychometric drug intake was treated with acupuncture, pharmacopuncture, and traditional Korean medicine for 30 days. We provided the patient with herbal medicines including Ondam-tang-gagam (溫膽湯加減), Pumsimgieum-gagam (忿心氣陰加減), and Hoichunyanggyeok-san-gami (回春凉隔散加味). Symptoms were charted and evaluated using the Yin-deficiency questionnaire score, Yin-deficiency scale score, dry mouth symptom questionnaire, and visual analogue scale. Results: After treatment with Korean Medicine and pharmacopuncture, the frequency and degree of tremor has decreased, and degree of Xerostomia also improved. The Scores of Yin-deficiency questionnaire score, Yin-deficiency scale score, dry mouth symptom questionnaire, and visual analogue scale were also improved. And we could see reduction in the level of distribution of gastrointestinal heat at Digital Infrared Thermal Imaging test. The patient's Symtoms (Xerostomia as well as unspecified tremor) were improved after treated with Korean Medicine and pharmacopuncture. Conclusion: Korean medicine treatments may be valuable for xerostomia caused by psychometric drug intake.

A study was conducted to investigate an optimal vibration frequency for mobile phones with just noticeable difference(JND). The just noticeable difference, Weber's law, is the minimum amount by which stimulus intensity must be changed in order to produce a noticeable variation in sensory experience. In order to find the optimal vibration frequency, sixteen frequencies ranged from 24Hz to 603Hz were selected. Subjects then wereasked to differentiate a pair of vibration frequencies. For the analysis, the psychometric function to determine the optimal vibration frequency and the logistic regression to validate the determined frequency were used. The results show that the 2nd order polynomial equations were best fitted for the JND psychometric function and the optimal mobile phone vibrations were determined at 140Hz, 151 Hz, and 160Hz. With the ogive-shaped psychometric function developed by the logistic regression, the results of this study was validated that the determined vibration frequencies (140Hz, 151 Hz, and 160Hz) were optimal mobile phone vibration frequencies.

Purpose: This study presents a translation, cultural adaptation, and psychometric evaluation of two instruments of the Fertility Awareness and Attitudes Towards Parenthood (FAAP) questionnaire (Conditions and Life changes) for use in South Korea. Methods: This methodological study included 166 university students for psychometric evaluation in the sixth step. The first five steps included forward translation, backward translation, committee review, assessment of content validity, and a pre-test. In the sixth step, psychometric properties, including internal consistency, construct validity, and criterion validity, were evaluated. Exploratory factor analysis and confirmatory factor analysis were conducted to identify the structure of the tool and to assess its validity. Results: The Korean version showed acceptable internal consistency. Cronbach's α was .73 for FAAP-Conditions and .83 for FAAP-Life changes. FAAP-Conditions showed a four-factor structure (social conditions, relationship with partner, external environment, and child-rearing support) and FAAP-Life changes had a two-factor structure (reward and burden). In the confirmatory analysis, CMIN/DF, TLI, IFI, SRMR, CFI, and RMSEA were satisfactory. Conclusion: This study provided preliminary evidence of the acceptability, reliability, and validity of the Korean version of the FAAP questionnaire in university students in South Korea. Nonetheless, further evaluation among Korean young adults is warranted to validate this instrument.

Recent scientific findings on the perception of facial attractiveness coupled with technological advances in computer imaging make it possible to measure the facial characteristics that nay be associated with specific judgments of facial appearance. These new methods can be used to produce psychometric norms of facial attractiveness which potentially could supplement the conventional population norms or averages used currently in orthodontic treatment planning. It is hypothesized that consideration of psychometric norms will enhance doctor-patient communication and lead to greater patient satisfaction at the completion of orthodontic treatment.
