Exploration of Students’ Perception of Academic Misconduct: Do Individual Factors, Moral Philosophy, Behavioral Intention, and Judgment Matter?Chiao Ling Huang,Shu-ChingYang &Chun-AnYang -2022 -Frontiers in Psychology 13.detailsUsing Reidenbach and Robin’s Multidimensional Ethics Scale, this study designs three scenarios related to academic dishonesty dilemmas to explore students’ moral philosophies, behavioral intentions, and ethical judgments and further examines whether students with different individual factors have differences in the above variables. A total of 605 students from two areas, Taiwan and Mainland China, participated in this study. The results indicated that Taiwanese students had stricter moral equity, relativism, and contractualism philosophies in the duplicate submission scenario than Mainland China students. (...) They also had stricter moral equity and relativism philosophies in the incomplete citation scenario. Similarly, relatively harsh relativism and contractualism philosophies accompanied by a low level of willingness to be a perpetrator in the failure to cite research published in other countries scenario were found. In addition, females applied relatively harsh moral equity and utilitarianism to all scenarios, reporting that they and their peers were less likely to engage in all AD activities. Graduates had a stricter egoism attitude toward duplicate submission and had stricter moral equity, relativism, and contractualism philosophies toward the behavior of incomplete citation. Graduate students also had strict moral equity, relativism, egoism, and contractualism beliefs in the failure to cite the foreign research scenario. Finally, regression analysis showed that moral equity, contractualism, and self-behavioral intention are significant predictors of students’ ethical evaluations in the three scenarios. (shrink)
An Investigation of College Students' Perceptions of Academic Dishonesty, Reasons for Dishonesty, Achievement Goals, and Willingness to Report Dishonest Behavior.ShuChingYang,Chiao-Ling Huang &An-Sing Chen -2013 -Ethics and Behavior 23 (6):501-522.detailsThis study investigated students? perceptions of their own and their peers? academic dishonesty (AD), their reasons for this dishonesty, their achievement goals, and their willingness to report AD (WRAD) within a Chinese cultural context. The results identified students? belief that their peers had a greater likelihood of engaging in AD and had more motivation to do so than did the students themselves. Gender and academic major did not affect students? WRAD. However, students were significantly more willing to report classmates than (...) friends. In terms of the participants? self-perceptions and peer perceptions concerning motivations for AD, more female students cited the lack of penalties as the reason for their own and their peers? AD, whereas male students more frequently cited their lack of attention to schoolwork as the reason for their own AD. In contrast to students in the social sciences, business students more frequently cited inadequate capabilities as the reason for their AD, and engineering students more frequently attributed their AD to self-interest. Multiple regression analysis demonstrated that three motivations for AD (opportunism, inadequacy, and self-promotion) could positively predict AD, whereas mastery-approach goals could negatively predict AD.

Attitudes and Behaviors Related to Academic Dishonesty: A Survey of Taiwanese Graduate Students.ShuChingYang -2012 -Ethics and Behavior 22 (3):218 - 237.detailsThis study examined academic dishonesty (AD) of 586 Taiwanese graduate students, the relationship between students' AD and their perceptions of AD of their peers, and their judgments regarding the seriousness of AD. Results showed that female students were more critical of AD than their male counterparts were in the areas of fraudulence, plagiarism, and falsification. Male students demonstrated more awareness of peer involvement in AD in the area of falsification than did female students. Master's students confessed to greater involvement in (...) AD compared with the PhD students. Doctoral students were more judgmental with respect to unethical acts of fraudulence, plagiarism, and falsification. (shrink)
Ethical Academic Judgments and Behaviors: Applying a Multidimensional Ethics Scale to Measure the Ethical Academic Behavior of Graduate Students.ShuChingYang -2012 -Ethics and Behavior 22 (4):281 - 296.detailsUsing Reidenbach and Robin's Multidimensional Ethics Scale, this study investigated the relationships between background variables and students' ethical evaluations, judgments, and behavioral intentions using 3 scenarios involving dilemmas related to academic dishonesty. The sample included 436 master's students and 142 doctoral students. The study found that the participants used a combination of ethical philosophies to make ethical decisions. The respondents judged improper citations more harshly than acts of inappropriate authorship or the falsification of data. The doctoral students generally considered behaviors (...) related to plagiarism and falsification to be more unethical than the master's students did, though no gender differences were found.

Bioethics education for practicing nurses in Taiwan: Confucian-western clash.Wan-PingYang,Ching-Huey Chen,Co-Shi Chantal Chao &Wei-Shu Lai -2010 -Nursing Ethics 17 (4):511-521.detailsTo understand the gaps between current bioethics education and the requirements of practicing nurses, a semistructured questionnaire was used to invite the directors of nursing departments at all 82 teaching hospitals in Taiwan to participate in this survey. The response rate was 64.6%. Through content analysis we obtained information about previous bioethical training, required themes and content, recommended teaching strategies, and difficulties with education and its application. The results suggest that Taiwanese nursing personnel need to be instilled with both self-cultivation (...) of morality and mental cultivation to acquire nursing virtues and the right attitudes toward bioethical issues. Good communication skills to prevent damage to the harmonious relationships between patients, their families and medical team members, policies that support the provision of systematic formal knowledge of ethics, small group training, and clarification of values were also shown to be important in bioethics education.

Nurses’ perspectives on moral distress: A Q methodology approach.Pei-Pei Chen,Hsiao-Lu Lee,Shu-He Huang,Ching-Ling Wang &Chiu-Mieh Huang -2018 -Nursing Ethics 25 (6):734-745.detailsBackground: Moral distress occurs when nurses experience ethical dilemmas. Issues related to these dilemmas are addressed in some nursing education courses. Nurses’ reaction to dilemma such as moral distress is relatively less noticed. Objective: This study aimed to identify and describe the various types of perceptions of moral distress exhibited by nurses. Research design: This study applied Q methodology to explore the perspectives of nurses regarding moral distress. Data were collected in two stages. First, in-depth interviews were conducted to collect (...) nurses’ opinions. Sentences that best fit the concepts of moral distress were extracted for the construction of Q statements. Second, nurses subjectively ranked these Q statements so that the relevant severity of moral distress could be determined using Q sorts. The study participants were nurses at a regional teaching hospital in northeast Taiwan. A total of 60 participants were invited to rank 40 moral distress Q statements. Ethical considerations: The study protocol was approved by the institutional review board of NationalYang-Ming University Hospital. Only the participants who signed an informed consent form participated in the study. The respondents’ right to withdraw from the study was respected. Findings: Five types of responses were identified regarding the nurses’ perspectives. These types were “conflict with personal values,” “excessive of workload,” “curbing of autonomy,” “constraint engendered by organizational norms,” and “self-expectation frustration.” Conclusion: The findings regarding nurses’ experiences of moral distress can be used to construct multifaceted policies and solutions and to incorporate ethical education in training programs.

Neuroplastic changes in resting-state functional connectivity after stroke rehabilitation.Yang-Teng Fan,Ching-yi Wu,Ho-Ling Liu,Keh-Chung Lin,Yau-yau Wai &Yao-Liang Chen -2015 -Frontiers in Human Neuroscience 9:148968.detailsMost neuroimaging research in stroke rehabilitation mainly focuses on the neural mechanisms underlying the natural history of post-stroke recovery. However, connectivity mapping from resting-state fMRI is well suited for different neurological conditions and provides a promising method to explore plastic changes for treatment-induced recovery from stroke. We examined the changes in resting-state functional connectivity (RS-FC) of the ipsilesional primary motor cortex (M1) in 10 post-acute stroke patients before and immediately after 4 weeks of robot-assisted bilateral arm therapy (RBAT). Motor performance, (...) functional use of the affected arm, and daily function improved in all participants. Reduced interhemispheric RS-FC between the ipsilesional and contralesional M1 (M1-M1) and the contralesional-lateralized connections were noted before treatment. In contrast, greater M1-M1 functional connectivity and disturbed resting-state networks were observed after RBAT relative to pre-treatment. Increased changes in M1-M1 RS-FC after RBAT were coupled with better motor and functional improvements. Mediation analysis showed the pre-to-post difference in M1-M1 RS-FC was a significant mediator for the relationship between motor and functional recovery. These results show neuroplastic changes and functional recoveries induced by RBAT in post-acute stroke survivors and suggest that interhemispheric functional connectivity in the motor cortex may be a neurobiological marker for recovery after stroke rehabilitation.

Analysis of Mutual Influence Relationships of Purchase Intention Factors of Electric Bicycles: Application of DEMATEL Taking into Account Information Uncertainty and Expert Confidence.Ching-Te Lin,Jen-JenYang,Wen-Jen Chiang,Jen-JungYang &Chin-ChengYang -2022 -Complexity 2022:1-13.detailsAs the negative environmental impacts of transportation systems become more severe, governments and environmental groups are seeking more sustainable transportation options, such as replacing fuel-powered vehicles with electric vehicles and expanding public transportation systems to reduce the number of people driving on their own, in order to reduce the environmental impacts of transportation systems. At present, the rapid expansion of public transportation systems is not an easy task and requires a long period of time to plan for expansion and construction, (...) so people are increasingly looking to find means of transportation that meet sustainable conditions as solutions. In this context, electric bicycles are one of the solutions that people can choose, with benefits such as energy saving, carbon reduction, effective air pollution reduction, and simple and labor-saving riding. However, in Taiwan, despite the many benefits of electric bicycles, their popularity is not high. Therefore, this study focuses on the factors that affect the purchase of electric bicycles in Taiwan. The Influential Network Relation Map generated by the Z-based Decision-making Trial and Evaluation Laboratory technique is used to describe the influence relationships among the factors and to establish the key evaluation criteria of electric bicycle purchase intention. The results indicate that vehicle price, safety, motor performance, battery life, and battery durability are the most important factors in purchasing electric bicycles. Furthermore, the power of motor is considered as the factor that most significantly affects other criteria, while safety and price are most likely to be affected by other criteria. This study has contributed to academia and industry, for the dependency weights of these factors are set to provide a scientific and systematic way to show how consumers think in the decision-making process and to provide more reliable information and management implications for the electric bicycle industry.

Study of fractions in elementary mathematics textbooks from Finland and Taiwan.Der-ChingYang -2017 -Educational Studies 44 (2):190-211.detailsThis study examines the different ways in which fractions are dealt with in two elementary mathematics textbook series: Kang Hsuan in Taiwan and Laskutaito in Finland. The results showed that the total number of fraction questions in Laskutaito is higher than that in KH and that Laskutaito highlights the basic definition of fractions to help children develop higher levels of reasoning. Fraction questions in Laskutaito were presented with a number of pictorial representations to clarify the concepts. Laskutaito includes more symbolic (...) representation of questions. Moreover, the questions posed in the Laskutaito reflect real-life situations, whereas the questions posed in KH do not connect with real life. The implications of this study are discussed and suggestions for future studies are made in this paper. (shrink)

Estimating Average Treatment Effects Utilizing Fractional Imputation when Confounders are Subject to Missingness.ShuYang &Nathan Corder -2020 -Journal of Causal Inference 8 (1):249-271.detailsThe problem of missingness in observational data is ubiquitous. When the confounders are missing at random, multiple imputation is commonly used; however, the method requires congeniality conditions for valid inferences, which may not be satisfied when estimating average causal treatment effects. Alternatively, fractional imputation, proposed by Kim 2011, has been implemented to handling missing values in regression context. In this article, we develop fractional imputation methods for estimating the average treatment effects with confounders missing at random. We show that the (...) fractional imputation estimator of the average treatment effect is asymptotically normal, which permits a consistent variance estimate. Via simulation study, we compare fractional imputation’s accuracy and precision with that of multiple imputation. (shrink)

Psychophysiological factors as predictors of second language writing achievement in a computer-based test.Shu-Ping Lee,Shujen Lee Chang,Hui-Kai Su,Zhen-Yang Cui &Shin-Da Lee -2022 -Frontiers in Psychology 13:958938.detailsSleep quality, personality, and cognitive load potentially increase second language writing (SLW) anxiety and subsequently affect SLW achievement. This study investigates the predictions of sleep quality, personality (social inhibition/ negative affectivity), and cognitive load (content/ computer) toward SLW anxiety and achievement in a computer-based test. Participants included 172 voluntary undergraduates majoring in English as foreign language. SLW anxiety in a computer-based test, sleep disturbance, personality and cognitive load was assessed with the SLW Anxiety Inventory, Pittsburg Sleep Quality Index, Type-D Personality, (...) and cognitive load questionnaires. A structural equation modeling approach was applied to examine the interdependence among the observed variables. An adequate-fit SLW anxiety model was built (X2 = 6.37,df = 6,p = 0.383,NFI = 0.97,CFI = 1.00,RMSEA = 0.02; R-squared multiple correlations: SLW anxiety in a computer-based test = 0.19, computer-based SLW achievement = 0.07). The structural model showed that sleep disturbance (+0.17), social inhibition personality (+0.31), and computer-induced cognitive load (+0.16) were significant predictors of SLW anxiety in a computer-based test. Subsequently, SLW anxiety in a computer-based test (−0.16) and computer-induced cognitive load (−0.16) were significant negative predictors of computer-based SLW achievement. (shrink)
Association of Chinese herbal medicine use with the depression risk among the long-term breast cancer survivors: A longitudinal follow-up study.Shu-YiYang,Hanoch Livneh,Jing-Siang Jhang,Shu-Wen Yen,Hua-Lung Huang,Michael W. Y. Chan,Ming-Chi Lu,Chia-Chou Yeh,Chang-Kuo Wei &Tzung-Yi Tsai -2022 -Frontiers in Psychology 13.detailsBackgroundBreast cancer patients are at elevated risk of depression during treatment, thus provoking the chance of poor clinical outcomes. This retrospective cohort study aimed to investigate whether integrating Chinese herbal medicines citation into conventional cancer therapy could decrease the risk of depression in the long-term breast cancer survivors.MethodsA cohort of patients aged 20–70 years and with newly diagnosed breast cancer during 2000–2008 was identified from a nationwide claims database. In this study, we focused solely on survivors of breast cancer at (...) least1 year after diagnosis. After one-to-one matching for age, sex, and baseline comorbidities, breast cancer patients who received and did not receive CHM treatment were enrolled. The incidence rate and hazard ratio citation for depression between the two groups was estimated at the end of 2012. A Cox proportional hazard model was constructed to examine the impact of the CHM use on the risk of depression.ResultsDuring the study period, the incidence rate of depression was significantly lower in the treated cohort than in the untreated cohort [8.57 compared with 11.01 per 1,000 person-years citation], and the adjusted HR remained significant at 0.74 in a Cox proportional hazards regression model. The corresponding risk further decreasing to 43% among those using CHM for more than 1 year.ConclusionFinding from this investigation indicated that the lower risk of depression observed in breast cancer patients treated with CHM, suggesting that CHM treatment should be considered for disease management toward breast cancer. Yet, the optimal administered dose should be determined in further clinical trials. (shrink)
Number sense strategies used by 6th‐grade students in Taiwan.Der‐ChingYang -2005 -Educational Studies 31 (3):317-333.detailsIn an interview setting, 21 6th‐graders from four public schools in south Taiwan were asked a series of questions, related to whole and decimal numbers, designed to assess their number sense. Eight students were randomly selected from both low and middle performance levels, and five were selected from a high‐performance level, according to their mathematical capabilities. Results indicated that, regardless of performance level, very few number sense strategies were used. The evidence also revealed that Taiwanese students tended to apply rule‐based (...) methods and standard written algorithms to explain their reasoning. Their inclination to use paper‐and‐pencil procedures narrowed their thinking and reasoning powers: this heavy reliance on written algorithms seemed to be a major impediment to the development of number sense.

Relationships among computational performance, pictorial representation, symbolic representation and number sense of sixth‐grade students in Taiwan.Der‐ChingYang &Fang‐Yu Huang -2004 -Educational Studies 30 (4):373-389.detailsTwenty classes in ten schools with 627 sixth?grade students in five cities in Taiwan participated in this study. The research provides information on the performance differences among written computation, pictorial representation, symbolic representation and number sense. The results of One?way ANOVA analysis indicate that significant difference was found among WCT, PRT, SRT and NST tests, with F=536.327, p=0.000. The a posteriori comparisons show for each pair (WCT vs PRT, WCT vs SRT, WCT vs NST, PRT vs SRT and SRT vs (...) NST) significant difference at the 0.001 level (p=0.000), except for the pair comparison between PRT and NST. This implies that these Taiwanese students were highly skilled in written computation but their written skills were not equally transferred to use of non?computational paths that depended on symbolic representation, pictorial representation and number sense to solve similar problems.

In search of the right fusion recipe: the role of legitimacy in building a social enterprise model.Yung-KaiYang &Shu-Ling Wu -2016 -Business Ethics: A European Review 25 (3):327-343.detailsSocial enterprises, as typical hybrid organisations, are embedded in a plural institutional environment in which some stakeholders regard achieving social goals as fundamental, while others see economic profit as the priority. A great challenge for social enterprises is dealing with the conflicts resulting from the diverse expectations of stakeholders. Based on the existing works on organisational legitimacy and the social business model, we propose a legitimacy-based social enterprise model composed of three main phases, namely, legitimacy proposition, legitimacy strategy planning, and (...) legitimacy strategy implementation. Our model is meant to serve as an effective legitimacy-building tool for social enterprises of various kinds. (shrink)
An investigation of 3rd‐grade Taiwanese students' performance in number sense.Der‐ChingYang &Mao‐Neng Fred Li -2008 -Educational Studies 34 (5):443-455.detailsThe main purpose of this study was to investigate the number sense performance of 3rd?graders in Taiwan, and to diagnose areas of weakness or deficiency in number sense development. A total of 808 3rd?graders participated in this study. The results indicated that these students did not perform well on each of the five number sense components (correct rates approx. 34%), and they appeared worst on the performance of ?Judging the reasonableness of computational results?. Boys and girls did not show any (...) appreciable difference in their ability to solve number sense problems. The importance of number sense should be highlighted both by teachers and in textbooks and more time and opportunity provided for students to work on this type of exercise at lower grade levels. This would require that ?drill and practice? exercises in mathematics should not indeed be over? taught, and the teaching of number sense to children should begin as early as possible. (shrink)
A Cross-Sectional Study of Individual Learning Passion in Medical Education: Understanding Self-Development in Positive Psychology.Shu-E. Zhang,Si-ao Ge,Jing Tian,Qing-lin Li,Ming-si Wang,Xiao-he Wang,Meng Zhang,Ji-Yang Zhao,Li-binYang,De-pin Cao &Tao Sun -2022 -Frontiers in Psychology 13.detailsBackgroundBoosting the individual learning passion of medical students is a novel approach to improve their academic performance. It facilitates the medical education reform, motivating both policymakers and educators to focus on the function of positive psychology in the career development of medical students. Therefore, this study aimed to assess the status of two types of learning passion; to clarify the relationship between self-esteem and two types of learning passion among Chinese medical students; to examine the mediating role of psychological capital (...) in the relationship between self-esteem and two types of learning passion, respectively; and to identify the moderating role of professional identity in the relationship between PsyCap and two types of learning passion, respectively.MethodsA cross-sectional online survey was conducted from April to June 2016 in China. A total of 1,218 valid questionnaires were collected from four medical schools.ResultsSelf-esteem significantly and positively influenced medical students’ PsyCap.ConclusionTwo types of learning passion of medical students are positively influenced by self-esteem and PsyCap. Medical students with high-level self-esteem should possess strong PsyCap, which augments their harmonious as well as obsessive learning passion. Moreover, the positive effect of medical students’ PsyCap on harmonious learning passion is more notable among those with a lower professional identity. Finally, this study argues that strengths-based interventions of self-esteem and PsyCap are a beneficial approach for future enhancing learning passion in the domain of medical education. (shrink)
Optimal Time Intervals in Two-Stage Takeover Warning Systems With Insight Into the Drivers’ Neuroticism Personality.Wei Zhang,Yilin Zeng,ZhenYang,Chunyan Kang,Changxu Wu,Jinlei Shi,Shu Ma &Hongting Li -2021 -Frontiers in Psychology 12.detailsConditional automated driving [level 3, Society of Automotive Engineers ] requires drivers to take over the vehicle when an automated system’s failure occurs or is about to leave its operational design domain. Two-stage warning systems, which warn drivers in two steps, can be a promising method to guide drivers in preparing for the takeover. However, the proper time intervals of two-stage warning systems that allow drivers with different personalities to prepare for the takeover remain unclear. This study explored the optimal (...) time intervals of two-stage warning systems with insights into the drivers’ neuroticism personality. A total of 32 drivers were distributed into two groups according to their self-ratings in neuroticism. Each driver experienced takeover under the two-stage warning systems with four time intervals. The takeover performance and subjective opinions for time intervals and situation awareness were recorded. The results showed that drivers in the 5-s time interval had the best takeover preparation. Furthermore, both the 5- and 7-s time intervals resulted in more rapid takeover reactions and were rated more appropriate and useful than the 3- and 9-s time intervals. In terms of personality, drivers with high neuroticism tended to take over immediately after receiving takeover messages, at the cost of SA deficiency. In contrast, drivers with low neuroticism responded safely by judging whether they gained enough SA. We concluded that the 5-s time interval was optimal for drivers in two-stage takeover warning systems. When considering personality, drivers with low neuroticism had no strict requirements for time intervals. However, the extended time intervals were favorable for drivers with high neuroticism in developing SA. The present findings have reference implications for designers and engineers to set the time intervals of two-stage warning systems according to the neuroticism personality of drivers. (shrink)
The Impact of Different Types of Auditory Warnings on Working Memory.Zhaoli Lei,Shu Ma,Hongting Li &ZhenYang -2022 -Frontiers in Psychology 13.detailsAuditory warnings have been shown to interfere with verbal working memory. However, the impact of different types of auditory warnings on working memory tasks must be further researched. This study investigated how different kinds of auditory warnings interfered with verbal and spatial working memory. Experiment 1 tested the potential interference of auditory warnings with verbal working memory. Experiment 2 tested the potential interference of auditory warnings with spatial working memory. Both experiments used a 3 × 3 mixed design: auditory warning (...) type was between groups, and task condition was within groups. In Experiment 1, earcons and spearcons but not auditory icons worsened the performance on the verbal serial recall task in the identify-warning condition, compared with that in the no-warning or ignore-warning conditions. In Experiment 2, only identifying earcons worsened the performance on the location recall task compared with performance without auditory warnings or when auditory warnings were ignored. Results are discussed from the perspective of working memory resource interference, and their practical application in the selection and design of auditory warning signals is involved. (shrink)
Atypical Relationships Between Neurofunctional Features of Print-Sound Integration and Reading Abilities in Chinese Children With Dyslexia.Zhichao Xia,TingYang,Xin Cui,Fumiko Hoeft,Hong Liu,Xianglin Zhang,Xiangping Liu &Hua Shu -2022 -Frontiers in Psychology 12.detailsConquering print-sound mappings is vital for developing fluent reading skills. In neuroimaging research, this ability can be indexed by activation differences between audiovisual congruent against incongruent conditions in brain areas such as the left superior temporal cortex. In line with it, individuals with dyslexia have difficulty in tasks requiring print-sound processing, accompanied by a reduced neural integration. However, existing evidence is almost restricted to alphabetic languages. Whether and how multisensory processing of print and sound is impaired in Chinese dyslexia remains (...) underexplored. In this study, we applied a passive audiovisual integration paradigm with functional magnetic resonance imaging to investigate the possible dysfunctions in processing character-sound and pinyin-sound associations in Chinese dyslexic children. Unexpectedly, the dyslexic group did not show reduced neural integration compared with typically developing readers in either character or pinyin experiment. However, the results revealed atypical correlations between neural integration and different reading abilities in dyslexia. Specifically, while the neural integration in the left inferior frontal cortex in processing character-sound pairs correlated with silent reading comprehension in both children with and without dyslexia, it was associated with morphological awareness in controls but with rapid naming in dyslexics. This result indicates Chinese dyslexic children may not use the same grapho-semantic processing strategy as their typical peers do. As for pinyin-sound processing, while a stronger neural integration in the direction of “congruent > incongruent” in the left occipito-temporal cortex and bilateral superior temporal cortices was associated with better oral reading fluency in the control group, an opposite pattern was found in dyslexia. This finding may reflect dyslexia's dysfunctional recruitment of the regions in grapho-phonological processing, which further impedes character learning. (shrink)
Doubly robust estimators for generalizing treatment effects on survival outcomes from randomized controlled trials to a target population.Xiaofei Wang,ShuYang &Dasom Lee -2022 -Journal of Causal Inference 10 (1):415-440.detailsIn the presence of heterogeneity between the randomized controlled trial (RCT) participants and the target population, evaluating the treatment effect solely based on the RCT often leads to biased quantification of the real-world treatment effect. To address the problem of lack of generalizability for the treatment effect estimated by the RCT sample, we leverage observational studies with large samples that are representative of the target population. This article concerns evaluating treatment effects on survival outcomes for a target population and considers (...) a broad class of estimands that are functionals of treatment-specific survival functions, including differences in survival probability and restricted mean survival times. Motivated by two intuitive but distinct approaches, i.e., imputation based on survival outcome regression and weighting based on inverse probability of sampling, censoring, and treatment assignment, we propose a semiparametric estimator through the guidance of the efficient influence function. The proposed estimator is doubly robust in the sense that it is consistent for the target population estimands if either the survival model or the weighting model is correctly specified and is locally efficient when both are correct. In addition, as an alternative to parametric estimation, we employ the nonparametric method of sieves for flexible and robust estimation of the nuisance functions and show that the resulting estimator retains the root- n n consistency and efficiency, the so-called rate-double robustness. Simulation studies confirm the theoretical properties of the proposed estimator and show that it outperforms competitors. We apply the proposed method to estimate the effect of adjuvant chemotherapy on survival in patients with early-stage resected non-small cell lung cancer. (shrink)
