  • This study is a methodological research study to develop an instrument to measure in patients with cancer and to test the validity and reliability of the instrument. The research procedure was as follows : 1) The first step was to develop conceptual framework based on a comprehensive review of the literature and in-depth interviews with patients with cancer. This conceptual framework was organized in to three dimensions (the intrapersonal dimension, the significant-other and context related dimension, the transcendental dimension). Initially 59 items were adopted. 2) These items were analyzed through the index of content validity(CVI) and 53 items were selected which met more than 80% on the CVI. 3) The pretest was carried out with 87 patients with cancer. After the pretest results were analyzed by item analysis, 44 items were selected. A second test of content validity was conducted and 6 items were eliminated considering the 80% CVI. 4) To test for reliability and validity, data collection was done during the period from January 25, 1999, to February 26, 1999. The subjects for the test were 160 patients with cancer and 185 healthy persons. analysis, item analysis and multitrait-multimethod method to analyze validity. The findings are as follows : 1) The Cronbach's alpha coefficient for internal consistency was .92 for the total 38 items and .79, .82, .85, for the three dimensions in that order. 2) The item analysis was based on the corrected item to total correlation coefficient( .30 or more) and information about the alpha estimate if this item was dropped from the scale. 3) As a result of the initial factor analysis using principal component analysis and varimax rotation, one item was deleted because of factor complexity (indiscriminate factor loadings). In the secondary factor analysis, 7 factors with eigenvalue of more than 1.0 were extracted and these factors explained 56 percents of the total variance. The seven factors were labeled as 'family relationship', 'emotional condition', 'physical discomfort', 'meaning and goal of life', 'contextual stimuli', 'change of body image', 'guilt feelings'. 4) The convergence effect between this instrument and the life satisfaction scale was identified and there was significant positive correlation(r= .52, p= .00). The discriminant validity between this instrument and the depression scale(CES-D) was tested and there was significant negative correlation(r= -.50, p= .00). The instrument for accessing the suffering of patients with cancer developed in this study was identified as a tool with a high degree of reliability and validity. In this sense, this tool can be effectively utilized for assessment in caring for patients with cancer.

  • Objectives: Given that Argentinian public-sector workers are highly exposed to stressful conditions, and that the psychometric properties of the widely used Perceived Stress Scale (PSS) should be evaluated in different settings, this work aimed to compare the psychometric properties of the Latin American Spanish PSS-10 and PSS-4 and to identify the optimal scale for stress assessment. Methods: A sample of 535 participants was randomly divided into 2 groups to evaluate dimensionality by exploratory and confirmatory factor analyses. The reliability of both scales was also evaluated. Convergent validity was estimated using the Executive Complaints Questionnaire, the average variance extracted, and the composite reliability. Discriminant validity was based on the correlation with the Utrecht Work Engagement Scale and the phi-square correlation between the components. Results: The factor analyses supported bidimensionality of the PSS-10 (stress and coping), which showed a better fit than the PSS-4. Moreover, the reliability of the PSS-10 was higher, whereas the PSS-4 did not achieve adequate values of internal consistency. The PSS-10 was also correlated significantly with all validation scales, and presented proper internal convergent and divergent validity. Conclusions: The PSS-10 is a reliable and structurally valid instrument to measure perceived stress and coping in a Latin American Spanish-speaking population with high work demands, and the findings of this study expand our knowledge on the geographical and sociocultural applicability of the PSS.

  • Purpose: The purpose of this present study was to develop and evaluate the psychometric properties of a needs scale for patients with cancer undergoing follow-up care (NS-C). Methods: A preliminary NS-C of 48 was derived from literature reviews and in-depth interviews with patients with cancer. Content validation of the items was established by oncology physicians and nurses. Each item was scored on a five-point Likert scale. The preliminary NS-C and Eastern Cooperative Oncology Group (ECOG) performance status questionnaires were administered to 873 patients with cancer recruited from three university hospitals. The data were analyzed using factor analysis, multidimensional scaling analysis, ANOVA, Pearson correlation coefficients, and Cronbach's alpha. Results: From the factor analysis, 25 significant items in six subscales were derived. The subscales were named physical symptoms, diet and exercise, support, relationship with health professionals, treatment/prognosis, and keeping mind under control. The NS-C also established item convergent and discriminant validity, and known-groups validity. Cronbach's alpha of the subscales ranged from .90 to .92. Conclusion: This study suggests that the NS-C is an easy, reliable and valid instrument to measure the needs of patients with cancer. Health professionals may use the NS-C for patients with cancer both in practice and research.

  • The aim of this study was to develop and validate measures of a mother's reaction to children's negative emotions. After construct factors of a mother's reaction to children's negative emotions based on the theoretical basis and existing scales were explored, the first preliminary items were extracted. After the content validity was confirmed by expert opinions, the second preliminary items were composed, and the initial survey was carried out. Using exploratory factor analysis, three principal factors and 21 items were revealed to be most suitable. The factors of the scale consist of emotion-coaching-reactions, oversensitive reactions, and emotion-minimizing-reactions, respectively. In addition, the reliability analysis and validation analysis of the scale was conducted, by means of surveying 413 elementary students. The internal coherence reliability and test-retest reliability were verified as was the general internal coherence and timing stability of the scale. There were three additional verifications to validate the scale. (1)For the evidence based on internal structure, the confirmatory factor analysis and convergent-discriminant evidence; this resulted in confirming the factor structure of the scale as being reliable. (2)In order to understand the relationships to other variables, the correlation analysis came in effect to the overall scale and each of its sub-factors, showing that they are significantly correlated with the scale of the child's perception on rearing attitudes of the mother. (3)As for evidence based on the consequences of the test, the correlation analysis produced a result showed that sub-factors of the scale have as significant correlation with the child's emotional intelligence and resilience.

  • Purpose: Cervical cancer can be prevented by regular cervical screening. Embarrassment has been reported as one important barrier to cervical screening uptake. The absence of appropriate instrumentation, however, has limited our understanding of the links between embarrassment and health care outcomes. The purpose of this study was to evaluate psychometric attributes of the uterine cervical cancer screening embarrassment questionnaire. Methods: A convenience sample for field study was recruited from four gynecological clinics in Gyeongju, Korea. Within a cross-sectional descriptive design, 339 women who had cervical screening completed self-administered measures of embarrassment including a visual analogue, general medical embarrassment, dispositional embarrassment, and Pap smear related negative emotion. Results: Rasch analysis of items demonstrated the evidence of one-dimensional construct and good 7-point rating scales functioning. Factor analysis revealed that uterine cervical cancer screening embarrassment was comprised of two domains-bodily manifestations and perceiving an undesirable social face. Construct validity was demonstrated by a high subscale-to-subscale correlation. Convergent and discriminant validity was evidenced by significant correlations with a 100 mm VAS scale, general medical embarrassment, and Pap smear related negative emotion. Known-group validity was established by comparing women with high versus low trait embarrassment. Both two sub-scales and overall scale demonstrated good internal reliability. Conclusion: The Uterine uterine cervical cancer screening questionnaire is a reliable and valid instrument suited to assessing the manifestations of embarrassment during screening. The use of instrument can be extended to understand the client's embarrassment undergoing health examinations which require the exposure of their private parts.
