Objective To translate the Resilience Questionnaire for Bipolar Disorder (RBD) into Chinese and evaluate the reliability and validity of the Chinese version of RBD in Chinese patients with bipolar disorder. Methods The Brislin translation model was used to translate the RBD into Chinese and backtranslate into English, and the Chinese version of RBD was developed after cross-cultural adjustment. A total of 233 outpatients and inpatients with bipolar disorder admitted to two tertiary hospitals in Guangzhou from April, 2019 to April, 2021 were included to investigate the reliability and validity of the Chinese version of RBD. Results Four factors were extracted from Chinese version of RBD by principal component analysis, and the cumulative contribution rate of variance was 66.68%. The confirmatory factor analysis displayed good fitness (x²/df = 2.84, RMSEA = 0.078, RMR = 0.049, GFI = 0.913, IFI = 0.906, TLI = 0.935). The Chinese version of RBD consisted of 23 statements in four dimensions (self- management, turning point, self-care and interpersonal support), with another 2 independent scoring items. The criterion validity was 0.559 (P < 0.001) when compared with the Chinese version of the Connor-Davidson Resilience Scale. The content validity was 0.987 in total scale (ranged from 0.800 to 1.000 in item level), and scale-level content validity index based on the universal agreement method was 0.913. This scale performed well in the Cronbach's coefficient of the scale (Cronbach's a=0.952) and its dimensions (0.847- 0.894), and the split-half reliability was 0.822 (P<0.001). Conclusion The Chinese version of RBD has good reliability and validity, which is applicable for the evaluation of resilience in Chinese patients with bipolar disorder [ABSTRACT FROM AUTHOR]

Objective To Chinesize the Nursing Home Care-related Quality of Life Scale (NHC-QoL) and to test its reliability and validity. Methods According to the Brislin model, the NHC-QoL scale was translated into Chinese and cross-cultural debugging was carried out. Using convenience sampling method, 198 elderly people from 4 nursing institutions in Shiyan city were investigated by questionnaire from March to July 2023 to evaluate the reliability and validity of the scale. Results There were 14 items in the Chinese version of NHC-QoL. The content validity index of each item was 0.7-1.0, and the content validity index of the scale was 0.929. Exploratory factor analysis extracted 5 common factors, which could explain 67.914% of the total variation. After discussion within the research group, the common factors were reduced to 2 common factors namely environment and service (11 items) and social interaction (3 items). The total Cronbach's α coefficient of the scale was 0.758 and the test-retest reliability was 0.783. Conclusion The Chinese version of NHC-QoL scale has good reliability and validity and can be used to evaluate the quality of life of the elderly in nursing institutions. [ABSTRACT FROM AUTHOR]

The Specific Affect Coding System (SPAFF), developed by Gottman, has been used to predict the stability of a marriage by observing interaction and emotional expression between couples. In recent observational studies of couples, the SPAFF has been recognized as the best evidence of construct and criterion validity. However, habitual behaviors derived from traditional Chinese culture, such as discouraging expression, indirect communication, and emotion suppression, may impede exploration in emotional expression. Therefore, it is necessary to explore the construct of emotional expression and reflect the essence of couple interaction through observational approaches. The aims of this study were to develop a culturally validated Chinese version of the SPAFF (SPAFF-C-24) and examine its appropriateness for use in marital and couple studies in Taiwan. Using a methodology that combines translational study, expert panel review, and small-scale study with 20 couple dyads, we established the reliability and validity of the SPAFF-C-24 through expert validity, inter-rater reliability, and criteria-related validity. The SPAFF-C-24 was reviewed by 10 experts, who found that the Content Validity Index (CVI) ranged from .79~ .96, indicating a reliable instrument with good content validity. Throughout the coder training with 20 couples in a small-scale study, the mean consistency between two coders with the agreement score in husbands and wives were .82 and .70, respectively. The mean interrater stability with Kappa values in husbands and wives were .53 and .57, respectively. Acceptable coding stability was thus endorsed with the overall agreement of 85.4% and its stability with a mean Kappa value of .55 among coders. In the criteria-related validity, the negative/neutral emotional aspects of the SPAFF-C-24 were significantly correlated with the scores in the Brief Version of Chinese Marital Affection Scale, Marital Quality Scale, and Couple Interaction Scale. Nevertheless, only partial correlations were identified between positive emotional aspects of the SPAFF-C-24 and those aforementioned subscales. In conclusion, the newly derived SPAFF-C-24 could be used to observe affective expressiveness among Chinese couples in Taiwan. However, the appropriateness of added codes and positive affects in the SPAFF-C-24 requires further validation through a large-scale study. [ABSTRACT FROM AUTHOR]

Objective　To develop the knowledge-attitude-practice(KAP) scale for preventive treatment of disease through constitution of Chinese medicine(KAP-PTDCCM) and test its reliability and validity, in order to provide an assessing tool for health management in preventive treatment through constitution of Chinese medicine. Methods　The KAP-PTDCCM was initially developed by referring to literature review combined with expert opinion based on the KAP Theory. A convenience sample of 922 students from three universities in Xinjiang and Beijing were investigated. Reliabilities of KAP-PTDCCM were tested by internal consistency reliability and split-half reliability. Validities of KAP-PTDCCM were tested by construct validity, convergent validity and discriminant validity. Results　The KAP-PTDCCM consisted of 24 items belonging to three dimensions: Knowledge(8 items), Belief/ Attitude(9 items), and Practice (7 items). The total Cronbach′s α value of KAP-PTDCCM was 0. 925(>0. 9) and varied from 0. 887 to 0. 943(>0. 8) for its three dimensions. Split-half reliability was 0. 960. Results of exploratory factor analysis were in accordance with KAP theory, and the cumulative contribution rate of the top three factors was 66. 33%. The indexes of confirmatory factor analysis showed a good fitness of the model. Convergent validity showed that correlation coefficients ranged from 0. 538 to 0. 838(P<0. 05), and discriminant validity showed that correlation coefficients ranged from 0. 096 to 0. 541(P<0. 05). The successful rate was 100% according to the convergent validity and discriminant validity tests. Conclusion　The 24-item scale of KAP-PTDCCM seems to show good reliability and validity for the application in evaluating the knowledge, attitude, practice, and health management effect of preventive treatment of disease through constitution of Chinese medicine.

To explore the influencing factors and mechanism of people’s trust on autonomous vehicles(AVs), the trust model of AVs was designed from six perspectives: information content, information carrier, information channel, system transparency, technical capability and situation management. The structure validity, convergent validity and discriminant validity of confirmatory factor analysis, the intermediary effect analysis and path analysis were used for the fitting test of the structural equation model. It was found that information channel, system transparency and information carrier have significant effect on AVs trust. Information content, information carrier and information channels not only affect AVs trust directly, but also affect AVs trust through the intermediary variable of system transparency.

Objectives: With the continuous popularity of social network products and applications, there are more and more ways to obtain location check-in data. The judgement of friendship based on check-in data is one of the most popular research directions of location based social networks (LBSN). However, social network data is often difficult to obtain in advance. In order to solve the problem of friend relationship judgement based on location check-in data only, this paper proposed a friend relationship judgment method based on an improved gravity model. Methods: Firstly, the information gain was used to calculate the influence of different feature parameters on friendship judgment, and two feature parameters, residence distance and spatial temporal co ⁃occurrence zone, were selected as consequences. Secondly, the gravity model was improved according to the selected feature parameters, and the model's value range was mapped from 0 to 1 by using Sigmoid function, to facilitate the judgement of friend relationship and calibration of model parameters. Finally, the parameters of the model were calibrated by logistic regression, and the prediction of friend relationship was realized on the Gowalla and Brightkite datasets. Results: Multiple experiments were conducted. Part of check-in data were selected to test the validity of feature parameters. The AUC (area under the curve) value of the spatial temporal co-occurrence zone parameter on the Gowalla dataset was 0.710, and the AUC value in the Brightkite dataset was 0.760. The residence distance parameter on the Gowalla dataset got an AUC value of 0.634, and 0.647 on the Brightkite dataset. By setting different degrees of balance, the improved gravity model was used to conduct friend relationship prediction experiments. As the data imbalance increased, the accuracy increased, while the recall rate and Fvalue decreased. However, the model still had a high accuracy and recall rate even with an imbalance of 1∶150. The accuracy rate was 0.846 1 and the recall rate was 0.788 5 when the Gowalla dataset as the training dataset while the test was performed on the Brightkite dataset. The accuracy rate was 0.859 1, and the recall rate was 0.853 7 when the Brightkite dataset as the training dataset while the test was performed on the Gowalla dataset. The contrast experiment with the friend relationship probability model shows that the recall rate of the contrast model dropped from 0.75 to almost 0 with the increase of the threshold. The experimental results above show that the selected feature parameters and the proposed model have a good predictive effect on the judgment of friend relationship. Conclusions: The proposed method can realize friend relationship judgment under the condition of only relying on location check-in data. The model has better stability between datasets from different sources, and the overall performance of this method is significantly higher than that of the comparison method. [ABSTRACT FROM AUTHOR]

In the digital age, high technology brings people with high emotional demand. It is also true for the built environment. In the existing post-occupancy evaluation (POE) of the built environment, methods focusing on user's emotional experience are always qualitative instead of quantitative, and also lack framework which could integrate digital tools. Based on the multidimensional interaction between people and the built environment in the digital age, this study introduces the affection evaluat ion scale in the field of psychology, combining big data approaches and integrating quantitative and qualitative tools to explore the multidimensional affection evaluation methods applicable to the built environment. The evaluation of the High Line Park in New York City serves as an example to initially test the validity of the method. [ABSTRACT FROM AUTHOR]

Objective · To develop a knowledge-attitude-practice questionnaire for mechanical prophylaxis of deep venous thrombosis for orthopedic nurses in China, and analyze its reliability and validity. Methods · On the basis of literature review, combined with the characteristics of orthopedic diseases and orthopedic nurses, a preliminary questionnaire for mechanical prophylaxis of deep venous thrombosis was prepared. In January 2020, two rounds of expert letter consultation were conducted to demonstrate and modify the items in the first draft and form the test version of the questionnaire for mechanical prophylaxis of deep vein thrombosis. In March 2020, tests were conducted among 620 orthopedic nurses from 36 medical units in 13 cities in Jiangsu Province. Item analysis was carried out with critical ratio method and homogeneity test. Reliability analysis was carried out from internal consistency reliability, split-half reliability and retest reliability. Validity was analyzed from content validity and structure validity. Results · The first draft of the questionnaire contained 37 items; after the first round of expert consultation, 4 items were revised and 7 items were added; after the second round of expert consultation, a test version of the questionnaire containing 44 items was formed. A total of 620 questionnaires were distributed. The effective recovery rate of the questionnaire was 96.77%. The critical ratio method showed that the item decision values t, which reflected the t-test results of independent samples of high and low groups, ranged from 5.89 to 20.31, and the difference was statistically significant (all P<0.05). The homogeneity test showed that Pearson correlation coefficient r, which reflected the correlation between the score of each item and the total score of the scale, ranged from 0.49 to 0.79, and the difference was statistically significant (all P<0.05). Therefore, 44 items were retained after item analysis. The Cronbach's α coefficient reflecting the internal consistency of the total questionnaire was 0.893, the Spearman-Brown coefficient reflecting the half-fold reliability was 0.794, and the intraclass correlation coefficient reflecting the retest reliability was 0.909. The scale-level content validity index reflecting content validity was 0.926 and the item-level content validity index was 0.833 - 1. Kaiser-Meyer-Olkin measure of sampling adequacy and Bartlett's sphericity test chi-square value which reflected the structure validity were 0.883 and 12 560.176 (df=666, P<0.05) respectively. These values indicated that the questionnaire was suitable for exploratory factor analysis. In addition, 7 items were deleted according to the absolute value of factor load. Finally, 37 items remained. Seven common factors with eigenvalue greater than 1 were extracted. The 7 common factors were named the act of mechanical prophylaxis, risk perception of mechanical prophylaxis, indications of mechanical prophylaxis, contraindications of mechanical prophylaxis, conceptual cognition of mechanical prophylaxis, mechanical preventive response and health education cognition of mechanical prophylaxis, respectively. The cumulative variance contribution rate was 61.992%. Conclusion · The questionnaire in this study shows good reliability and validity. It can be used as an investigation tool to study the current attitude, knowledge and behavior of mechanical prophylaxis of orthopedic nurses. [ABSTRACT FROM AUTHOR]

In order to effectively extract the key features from the extremely short texts, this paper proposed an extremely short text classification model based on SVM. Firstly, by the data cleansing on the original data, the cleaned data was processed by the jieba segmentation and TF-IDF. Then the 1-0 test verified the validity of the model. Finally, 9906 pieces of extremely short texts in Wuhu city community management platform were used as the sample in this experiment. The results show that the proposed method can effectively improve classification accuracy compared to other traditional methods, such as naive Bayes, logistic regression and decision tree. At the same time, the matching results in terms of misclassification and accuracy are more balanced. [ABSTRACT FROM AUTHOR]

Based on the third-generation wave observation model WAVEWATCH-III, CCMP and ERA wind fields were respectively used as driving fields to conduct numerical simulation, validity test and wave analysis of effective wave height caused by typhoon "rainbow" in the South China Sea in October 2015. The study found that: three typhoon track points in the South China Sea are selected for parameter test. By comparing the simulated wave height with the measured wave height, the correlation coefficient of ERA wind field is 0.867~0.932, the correlation coefficient of CCMP wind field is 0.871~0.901, and the absolute deviation value of the two wind fields is 0.043~0.347 m. The effective wave height diagram of wind field simulation was made, and it was found that the simulation effect of the two wind fields is better. The typhoon mainly affected the northwest of the Philippines islands in the east, the Taiwan Strait in the north, and the Beibu Gulf sea area in the west. The maximum wave height of the coastal waters during the typhoon period is over 9 m. [ABSTRACT FROM AUTHOR]
