In Puerto Rico, a questionnaire valid in content and reliability was required to measure the variable of academic stress in nursing students. Purpose: The aim of this study was to adapt transculturally and validate the Academic Stress Questionnaire (CEA) for its use in Puerto Rico. Materials and Methods: Used for the first phase of this study consisted in the evaluation of the validity of content and appearance, whereas the second phase was the actual administering of the questionnaire to 20 (twenty) nursing students, to pilot test its internal consistency using the Cronbach’s α test. Results: Validity of content and appearance allowed for the modification of the questionnaire into one, consisting of 42 items, thus eliminating 34 premises from the original 76 items the questionnaire was composed of. Furthermore, the appearance of the questionnaire was modified by placing the measuring scales in columns, adapting social, demographic, and academic data to the required Puerto Rican reality. The sections meant to measure the academic stress variables were left intact, except for the linguistics adaptation, which was accomplished by a team of experts in the Spanish language. With an α global of 0.80 and coefficients larger than 0.7 in the multi-item sub scales, which oscillated between 0.750 and 0.860, the questionnaire provides a high reliability. Conclusion: Although the values reported in this study are somewhat lower than previous research, they were comparable the Cronbach’s Alpha coefficients reported by Cabanach, in which the numbers reported are considered high (α > 0.70) which show acceptable confiability of the subscales included in the study and a high degree of consistency and thus can be relied upon in future research. In synthesis, the Academic Stress Questionnaire (CEA) modified and adapted, thoroughly fulfills the established criteria of confiability and validity to evaluate academic stress of Puertorrican nursing students.展开更多

Patients with vertigo often experience cognitive symptoms such as attention deficits, memory problems, and spatial perception difficulties. This study aimed to explore the cognitive impairments associated with Benign paroxysmal positional vertigo(BPPV) and Meniere's Disease(MD). A non-experimental group comparison design was used with 107 participants divided into three groups: Group I(clinically normal), Group II(BPPV), and Group III(MD). Participants completed a questionnaire with 10 cognition-related questions, and their responses were scored. The data were found to be non-normally distributed. The analysis revealed a significant difference in scores between Group I and both Group II and Group III. Chi-square tests showed that the responses to cognition-related questions varied among the groups, with Group II exhibiting more cognitive problems. Associated conditions like hypertension, diabetes, and hearing loss did not significantly influence the responses within each group. This study suggests a significant relationship between cognitive problems and patients with BPPV and MD. However, there was no association found between the cognitive problems experienced in BPPV and MD patients. These findings align with previous research indicating that vestibular disorders can lead to deficits in spatial memory, attention, and other cognitive functions. By understanding the link between cognition and vestibular disorders, we can improve diagnosis and rehabilitation services to enhance the quality of life for these patients.展开更多

We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination.展开更多

Methods A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls(24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children(N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients(ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. Results For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman’s correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from-0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. Conclusion The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.展开更多

But for the majority of patients, psychosocial and spiritual needs are neither addressed nor even considered a relevant factor by health care professionals. To measure such specific needs, the Spiritual Needs Questionnaire （SpNQ） was developed. The aim of this study was to validate the Chinese version of the SpNQ （SpNQ-Ch） and thus to measure psychosocial and spiritual needs of Chinese patients. METHODS： This was a cross-sectional study among 168 patients with chronic diseases who were recruited in the Changhai Hospital of Traditional Chinese Medicine, Shanghai, China using standardized questionnaires. We performed reliability and factor analyses, as well as analyses of variance, first order correlations and regression analyses. RESULTS： The 17-item SpNQ-Ch had a similar factorial structure as the original version with two main and three minor factors which accounted for 64% of variance, and internal consistency estimates （Cronbach＇s a） ranging from 0.51 to 0.81. Included were the 4-item scale Inner Peace Needs, the 5-item scale Giving/Generativity （with 2 sub-constructs, Praying and Sources）, and a Needs, the 5-item scale Religious Needs 3-item scale Reflection/Release Needs. In Chinese patients with cancer （63%）, pain affections （10%）, or other chronic conditions （23%）, the needs for Giving/Generativity （which refer to categories of Connectedness and Meaning） and Inner Peace Needs scored highest, while Religious Needs and the Reflection/Release Needs scored lower. CONCLUSION： The SpNQ-Ch is congruent with its primary version, and can be used in future studies with the mostly nonreligious patients from China. First findings indicate specific psychosocial and spiritual needs which should be addressed by health care professionals to support patients in their struggle with chronic illness in terms of psycho-emotional stabilization, finding hope and meaning, and thus achieving peaceful states of mind despite chronic illness.展开更多

METHODS: A cross-sectional sample of 460 Chinese patients with CHB was selected from the Outpatient Department of the Eighth Hospital of Xi'an, including CHB (CHB without cirrhosis) (n = 323) and CHB-related cirrhosis (n = 137). The psychometrics includes reliability, validity and sensitivity. Internal consistency reliability was measured using Cronbach's α. Convergent and discriminant validity was evaluated by item-scale correlation. Factorial validity was explored by principal component analysis with varimax rotation. Sensitivity was assessed using Cohen's effect size (ES), and independent sample t test between CHB and CHB-related cirrhosis groups and between alanine aminotransferase (ALT) normal and abnormal groups after stratifying the disease (CHB and CHB-related cirrhosis).RESULTS: Internal consistency reliability of the CLDQ was 0.83 (range: 0.65-0.90). Most of the hypothesized item-scale correlations were 0.40 or over, and all of such hypothesized correlations were higher than the alternative ones, indicating satisfactory convergent and discriminant validity. Six factors were extracted after varimax rotation from the 29 items of CLDQ. The eligible Cohen's ES with statistically significant independent sample t test was found in the overall CLDQ and abdominal, systematic, activity scales (CHB vs CHBrelated cirrhosis), and in the overall CLDQ and abdominal scale in the stratification of patients with CHB (ALT normal vs abnormal). CONCLUSION: The CLDQ has acceptable reliability, validity and sensitivity in Chinese (mainland) patients with CHB.展开更多

文摘The vestibular system connects the inner ear to the midbrain and subcortical structures and can affect cognition. Patients with vertigo often experience cognitive symptoms such as attention deficits, memory problems, and spatial perception difficulties. This study aimed to explore the cognitive impairments associated with Benign paroxysmal positional vertigo(BPPV) and Meniere's Disease(MD). A non-experimental group comparison design was used with 107 participants divided into three groups: Group I(clinically normal), Group II(BPPV), and Group III(MD). Participants completed a questionnaire with 10 cognition-related questions, and their responses were scored. The data were found to be non-normally distributed. The analysis revealed a significant difference in scores between Group I and both Group II and Group III. Chi-square tests showed that the responses to cognition-related questions varied among the groups, with Group II exhibiting more cognitive problems. Associated conditions like hypertension, diabetes, and hearing loss did not significantly influence the responses within each group. This study suggests a significant relationship between cognitive problems and patients with BPPV and MD. However, there was no association found between the cognitive problems experienced in BPPV and MD patients. These findings align with previous research indicating that vestibular disorders can lead to deficits in spatial memory, attention, and other cognitive functions. By understanding the link between cognition and vestibular disorders, we can improve diagnosis and rehabilitation services to enhance the quality of life for these patients.

文摘Despite the well-established benefits of regular physical activity(PA)on health,a large proportion of the world population does not achieve the recommended level of regular PA.Although affective experiences toward PA may play a key role to foster a sustained engagement in PA,they have been largely overlooked and crudely measured in the existing studies.To address this shortcoming,the Affective Exercise Experiences(AFFEXX)questionnaire has been developed to measure such experiences.Specifically,this questionnaire was developped to assess the following three domains:antecedent appraisals(e.g.,liking vs.disliking exercise in groups),core affective exercise experiences(i.e.,pleasure vs.displeasure,energy vs.tiredness,and calmness vs.tension),and exercise motivation(i.e.,attraction vs.antipathy toward exercise).The current study aimed to validate a Chinese version of the AFFEXX questionnaire(AFFEXX-C).In study 1,722 Chinese college students provided data for analyses of factorial,convergent,discriminant,criterion validity,and test-retest reliability of the AFFEXX-C.In addition,1,300 college students were recruited in study 2 to further validate its structural model.Results showed that the AFFEXX-C demonstrates a goodfit and reliability.Additionally,results further supported the hypothesized model based on previous research:antecedent appraisals predicted core affective exercise experiences,which in turn predicted attraction-antipathy toward physical exercise.The AFFEXX-C was found to be a reliable and valid measure of affective exercise experiences in a population of Chinese college students.
文摘AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination.
文摘Prototype landscape refers to the impressive scenes that one has experienced in his/her living environment before 20 years old.Based on the analysis of the existing literature,the authors compiled a standard scale type questionnaire by means of a field survey,which was about the influences of prototype landscape on one's landscape perception.Taking Likert scale as the main part,this questionnaire analyzed the influence of prototype landscape on landscape perception from perception,attitude,and behavior dimensions.In order to further improve its rationality,the authors tested some other aspects of this questionnaire,including logic validity,construct validity,congeniality reliability,split-half reliability,etc..The results validated that the questionnaire possessed good theoretical structure and validity target,which can evaluate various aspects of prototype landscape on one's landscape perception in an effective and reliable way.Therefore,the questionnaire put forward by this study not only enriched the studies of prototype landscape on landscape designing,but also provided an effective tool for quantitative analysis of "the influences of prototype landscape on one's landscape perception".
文摘BACKGROUND Displaced aggression occurs when a person encounters a provoking situation,is unable or unwilling to retaliate against the original provocateur,and subsequently aggresses against a target that is not the source of the initial provocation.The displaced aggression questionnaire(DAQ)was developed to measure individual differences in the tendency to displace aggression.AIM To develop a Dutch version of the DAQ and examine relationships between the DAQ and novel individual differences.METHODS The Dutch version of the DAQ was created using a back-translation procedure.Undergraduate students(n=413)participated in the current study.The questionnaires were administered online.RESULTS The results confirmed the original three-factor structure and showed good reliability and validity.We also found differential relationships between trait displaced aggression,social anxiety and cognitive distortions.CONCLUSION The results may indicate that distinct patterns exist in the development of the different dimensions of trait displaced aggression.This study adds to the growing cross-cultural literature showing the robustness of trait displaced aggression in several different cultures.

文摘Objective The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire(FFQ) among Chinese children aged 12-17 years. Methods A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls(24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children(N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients(ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. Results For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman’s correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from-0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. Conclusion The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.
文摘OBJECTIVE： Even in secular societies, a small portion of patients find their spirituality to help cope with illness. But for the majority of patients, psychosocial and spiritual needs are neither addressed nor even considered a relevant factor by health care professionals. To measure such specific needs, the Spiritual Needs Questionnaire （SpNQ） was developed. The aim of this study was to validate the Chinese version of the SpNQ （SpNQ-Ch） and thus to measure psychosocial and spiritual needs of Chinese patients. METHODS： This was a cross-sectional study among 168 patients with chronic diseases who were recruited in the Changhai Hospital of Traditional Chinese Medicine, Shanghai, China using standardized questionnaires. We performed reliability and factor analyses, as well as analyses of variance, first order correlations and regression analyses. RESULTS： The 17-item SpNQ-Ch had a similar factorial structure as the original version with two main and three minor factors which accounted for 64% of variance, and internal consistency estimates （Cronbach＇s a） ranging from 0.51 to 0.81. Included were the 4-item scale Inner Peace Needs, the 5-item scale Giving/Generativity （with 2 sub-constructs, Praying and Sources）, and a Needs, the 5-item scale Religious Needs 3-item scale Reflection/Release Needs. In Chinese patients with cancer （63%）, pain affections （10%）, or other chronic conditions （23%）, the needs for Giving/Generativity （which refer to categories of Connectedness and Meaning） and Inner Peace Needs scored highest, while Religious Needs and the Reflection/Release Needs scored lower. CONCLUSION： The SpNQ-Ch is congruent with its primary version, and can be used in future studies with the mostly nonreligious patients from China. First findings indicate specific psychosocial and spiritual needs which should be addressed by health care professionals to support patients in their struggle with chronic illness in terms of psycho-emotional stabilization, finding hope and meaning, and thus achieving peaceful states of mind despite chronic illness.

文摘AIM: To evaluate psychometrics of the Chinese (mainland) chronic liver disease questionnaire (CLDQ) in patients with chronic hepatitis B (CHB). METHODS: A cross-sectional sample of 460 Chinese patients with CHB was selected from the Outpatient Department of the Eighth Hospital of Xi'an, including CHB (CHB without cirrhosis) (n = 323) and CHB-related cirrhosis (n = 137). The psychometrics includes reliability, validity and sensitivity. Internal consistency reliability was measured using Cronbach's α. Convergent and discriminant validity was evaluated by item-scale correlation. Factorial validity was explored by principal component analysis with varimax rotation. Sensitivity was assessed using Cohen's effect size (ES), and independent sample t test between CHB and CHB-related cirrhosis groups and between alanine aminotransferase (ALT) normal and abnormal groups after stratifying the disease (CHB and CHB-related cirrhosis).RESULTS: Internal consistency reliability of the CLDQ was 0.83 (range: 0.65-0.90). Most of the hypothesized item-scale correlations were 0.40 or over, and all of such hypothesized correlations were higher than the alternative ones, indicating satisfactory convergent and discriminant validity. Six factors were extracted after varimax rotation from the 29 items of CLDQ. The eligible Cohen's ES with statistically significant independent sample t test was found in the overall CLDQ and abdominal, systematic, activity scales (CHB vs CHBrelated cirrhosis), and in the overall CLDQ and abdominal scale in the stratification of patients with CHB (ALT normal vs abnormal). CONCLUSION: The CLDQ has acceptable reliability, validity and sensitivity in Chinese (mainland) patients with CHB.
文摘The main purpose of this study was to assess the reliability and validity of the simplified Chinese STOP-BANG Questionnaire(SBQ)as a diagnosing and screening tool for obstructive sleep apnea hypopnea syndrome(OSAHS).Two hundred and ten patients with suspected OSAHS were recruited in this study.The simplified Chinese SBQ was completed twice before and after polysomnography(PSG)monitoring.SPSS 20.0 was used to analyze the test-retest reliability,discriminant validity,comparative validity and predictive validity of the SBQ.Fourteen patients were excluded on account of fragmentary data,and valid 196 were divided into four groups:non-OSAHS group(n=28,14.29%),mild OSAHS group(n=28,14.29%),moderate OSAHS group(n=31,15.81%)and severe OSAHS group(n=109,55.61%).The test-retest coefficient tor the first four items was 0.810,0.679,0.775,0.963 respectively and the total score of the STOP questionnaire was 0.854.The analysis of discriminant validity revealed that there were significant differences among four groups in the total score of the SBQ and scores of item 1,3,7 and 8,which were also validated between patients with normal blood oxygen saturation and different degrees of hypoxemia.The SBQ evaluation showed low consistency with diagnostic gold standard PSG(k=0.3O3,P<0.05).When taking apnea hypopnea index(AHI)≥5/h,≥15/h and≥30/h as cut-offs to evaluate the SBQ predictive value,the areas under ROC curve were 0.77,0.81 and 0.78,the sensitivity was 90.48%,93.57%and 93.33%,and corresponding negative predictive values were 40.74%,66.67%and 85.19%,respectively.It was suggested that the simplified Chinese version of SBQ had good reliability,and could distinguish the severity of OSAHS.Despite its limited diagnostic accuracy,the SBQ can be considered as an ideal tool for screening OSAHS with superior predictive validity.
