  • Technology adoption has been an important issue for researchers and practitioners. In this paper, we identified the relationships between intention of technology adoption and technological affinity and other psychometric characteristics. We believe that technology affinity may be one of the general psychometric traits of individuals, and thus people have a different affinity levels which may influence the technology adoption intention. As a result it was found that need for cognition and self efficacy had positive influence on technology affinity, and the affinity also positively affected adoption intention. In addition, it was also found that technology affinity displayed a mediating role for the consumers adoption intention with need for cognition and self efficacy.

  • Even experienced clinicians have difficulties in diagnosing posttraumatic stress disorder (PTSD) exactly, due to its diverse clinical features, which vary according to individuals, traumas, and various comorbid psychopathologies, and its related compensation issues. It is usually mandatory for clinicians and researchers to use screening and assessment tools when diagnosing and evaluating PTSD. To date, research has developed numerous PTSD screening and assessment tools ; therefore one of the cardinal issues is to select the best of the various tools, the one most suitable for the clinician's or researcher's purposes. This article reviews several currently-available subjective and objective instruments for the diagnosis and evaluation of PTSD and groups them according to whether they are Diagnostic and Statistical Manual for Mental Disorders-Correspondent Measures ; PTSD-Focused, Non-DSM-Correspondent Measures ; or Empirically Derived Measures. We present the instruments' psychometric properties and scoring methods and describe their merits and weak points, focusing on their practical usage.

  • Purpose: This study sought to develop the Breastfeeding Adaptation Scale-Short Form (BFAS-SF) for use at 4 weeks postpartum, to test its validity and reliability, and to examine its measurement invariance. The latent mean score of the BFAS-SF across multiple groups was also compared. Methods: This methodological research study was conducted to develop a short form of the BFAS and to test its psychometric properties and measurement invariance. Data were collected twice for measurement invariance testing. The sample included 431 and 272 breastfeeding mothers at 2 weeks and 4 weeks postpartum, respectively. Results: Confirmatory factor analysis supported six dimensions of the BFAS-SF at 4 weeks postpartum. Multi-group confirmatory factor analysis revealed evidence for invariance of the BFAS-SF according to employment status, parity, delivery mode, and the postpartum period. There were statistically significant latent mean differences. Mothers who were unemployed and who had a vaginal delivery showed significantly higher scores for breastfeeding confidence, sufficient breast milk, and baby's satisfaction with breastfeeding. Conclusion: The BFAS-SF is valid, reliable, and an appropriate instrument for assessing mothers' breastfeeding adaptation. It can be used to compare mean scores according to employment status and delivery mode.

  • Purpose: The purpose of this methodological study was to examine the validity and reliability of a translated Korean version of Templer's death anxiety scale among older adults. Methods: The translated Korean scale was administered to 203 older people who aged over 65 years. Exploratory factor analysis was utilized to assess the factor structure of the scale. Internal consistency of the scale was determined using Cronbach's ${\alpha}$ and Guttman's split-half coefficient. Results: Factor loadings of the scale ranged from .43 to .86. The scale showed good internal consistencies of both total scale (13 items, ${\alpha}=.83$) and three sub-scales: meaning of death (6 items, ${\alpha}=.77$), death-related event (5 items, ${\alpha}=.72$), and time of death (2 items, ${\alpha}=.80$). The concurrent validity compare with Fear of Death Scale was significant. The Cronbach's alpha and Guttman's split-half coefficient were .83 and .80, respectively. Conclusion: The findings of this study demonstrate that the Korean version of Templer's death anxiety scale had satisfactory validity and reliability to measure death anxiety among Korean older people.

  • Background: Cancers impose an increasing burden on health of the populations and individuals, but little is known about cancer patient satisfaction with care. The aim of this study was to assess the psychometric properties of the Persian version of European Organisation for Research and Treatment of Cancer (EORTC) In-Patsat32, as a recently developed questionnaire to assess cancer patient satisfaction with care and information provided during hospital admission. Materials and Methods: Complying with EORTC protocols, the Persian version of Inpatsat32 was translated and piloted in a small group of patients, then applied to 380 cancer patients admitted to different oncology wards in Tehran. Validity (convergent, discriminant, and divergent) and reliability of the tool was assessed through using multitrait analysis, factor analysis, intraclass correlations, Chronbach's alpha and test-retest (on a sample of 70 patients). Results: Good acceptance and high sensitivity of the questionnaire with low floor and ceiling effects were recognized, indicating power of the instrument to detect differences between groups with heterogeneous levels of satisfaction. Multitrait scaling analyses supported the convergent validity of the majority of scales (correlation coefficient >0.4) and favorable discriminant validity (item own scale correlation >0.8). There was no correlation between In-patsat32 scales and the EORTC-C30, which measures different concepts, confirming divergent validity of the tool. Internal consistency for all domains was high (${\alpha}$ >0.70) except for the hospital access score and the test-retest reliability was excellent (r=0.86-0.96). There was a weak responsiveness to change except for nurses technical skills. Principle component analysis confirmed five domains with much improved internal consistency (${\alpha}$ >0.9). Conclusions: The Persian version of the EORTC-in-patsat32 module is a reliable and valid instrument to measure cancer patient satisfaction with care received during their hospitalization period and can be utilized in clinical cancer research.

  • Background: This study examined the psychometric properties of the Bahasa Malaysia (BM) version of the European Organization for Research and Treatment of Cancer (EORTC) Colorectal Cancer-specific Quality Of Life Questionnaire (QLQ-CR29). Materials and Methods: We studied 93 patients recruited from University Malaya and Universiti Kebangsaan Medical Centers, Kuala Lumpur, Malaysia using a self-administered method. Tools included QLQ-C30, QLQ-CR29 and Karnofsky Performance Scales (KPS). Statistical analyses included Cronbach's alpha, test-retest correlations, multi-traits scaling and known-groups comparisons. A p vaue ${\leq}0.05$ was considered significant. Results: The internal consistency coefficients for body image, urinary frequency, blood and mucus and stool frequency scales were acceptable (Cronbach's alpha ${\alpha}{\geq}0.65$). However, the coefficients were low for the blood and mucus and stool frequency scales in patients with a stoma bag (${\alpha}=0.46$). Test-retest correlation coefficients were moderate to high (range: r = 0.51 to 1.00) for most of the scales except anxiety, urinary frequency, buttock pain, hair loss, stoma care related problems, and dyspareunia (r ${\leq}0.49$). Convergent and discriminant validities were achieved in all scales. Patients with a stoma reported significantly higher symptoms of blood and mucus in the stool, flatulence, faecal incontinence, sore skin, and embarrassment due to the frequent need to change the stoma bag (p < 0.05) compared to patients without stoma. None of the scales distinguished between patients based on the KPS scores. There were no overlaps between scales in the QLQ-C30 and QLQ-CR29 (r < 0.40). Conclusions: the BM version of the QLQ-CR29 indicated acceptable psychometric properties in most of the scales similar to original validation study. This questionnaire could be used to complement the QLQ-C30 in assessing HRQOL among BM speaking population with colorectal cancer.

  • The purpose of this paper was to evaluate hypothesized alternative models for the factor structure of the Korean Version of the Aberrant Behavior Checklist(K-ABC) using standardized samples. Confirmatory factor analyses of correlated factor models using the Jeroskog method were carried out. Analyses supported the two-factor processing model. When the achievement scale was added, a three factor model (two processing factors and an achievement factor) emerged. When factorially uncorrelated models were analyzed, fit indices proved to be improper.

  • Objectives: As quality of work-life (QWL) among nurses affects both patient care and institutional standards, assessment regarding QWL for the profession is important. Work-related Quality of Life Scale (WRQOLS) is a reliable QWL assessment tool for the nursing profession. To develop a Chinese version of the WRQOLS-2 and to examine its psychometric properties as an instrument to assess QWL for the nursing profession in China. Methods: Forward and back translating procedures were used to develop the Chinese version of WRQOLS-2. Six nursing experts participated in content validity evaluation and 352 registered nurses (RNs) participated in the tests. After a two-week interval, 70 of the RNs were retested. Structural validity was examined by principal components analysis and the Cronbach's alphas calculated. The respective independent sample t-test and intra-class correlation coefficient were used to analyze known-group validity and test-retest reliability. Results: One item was rephrased for adaptation to Chinese organizational cultures. The content validity index of the scale was 0.98. Principal components analysis resulted in a seven-factor model, accounting for 62% of total variance, with Cronbach's alphas for subscales ranging from 0.71 to 0.88. Known-group validity was established in the assessment results of the participants in permanent employment vs. contract employment (t = 2.895, p < 0.01). Good test-retest reliability was observed (r = 0.88, p < 0.01). Conclusion: The translated Chinese version of the WRQOLS-2 has sufficient validity and reliability so that it can be used to evaluate the QWL among nurses in mainland China.
