Preference relations have been widely used in group decision‐making (GDM) problems. Recently, a new kind of preference relations called fuzzy preference relations with self‐confidence (FPRs‐SC) has ...been introduced, which allow experts to express multiple self‐confidence levels when providing their preferences. This paper focuses on the analysis of additive consistency for FPRs‐SC and its application in GDM problems. To do that, some operational laws for FPRs‐SC are proposed. Subsequently, an additive consistency index that considers both the fuzzy preference values and self‐confidence is presented to measure the consistency level of an FPR‐SC. Moreover, an iterative algorithm that adjusts both the fuzzy preference values and self‐confidence levels is proposed to repair the inconsistency of FPRs‐SC. When an acceptable additive consistency level for FPRs‐SC is achieved, the collective FPR‐SC can be computed. We aggregate the individual FPRs‐SC using a self‐confidence indices‐based induced ordered weighted averaging operator. The inherent rule for aggregation is to give more importance to the most self‐confident experts. In addition, a self‐confidence score function for FPRs‐SC is designed to obtain the best alternative in GDM with FPRs‐SC. Finally, the feasibility and validity of the research are demonstrated with an illustrative example and some comparative analyses.
Preference relation has been one of the most useful tools for experts to express their comparison information over alternatives in group decision‐making (GDM) problems. Recently, a new type of ...preference relations called linguistic preference relations with self‐confidence (LPRs‐SC) has been proposed, which makes multiple self‐confidence levels into consideration when experts provide their preferences. This study focuses on the consensus reaching process for GDM with LPRs‐SC. To do that, some new operational laws for LPRs‐SC are presented. Subsequently, an iteration‐based consensus proposal for LPRs‐SC is proposed. In the proposal, we aggregate the individual LPRs‐SC using a self‐confidence indices‐based method which gives more importance to the most self‐confident experts. A self‐confidence score function is presented to derive the individual and collective priority vectors. Moreover, considering experts’ acceptable adjustment range of preference values, a two‐step feedback adjustment mechanism is utilized to improve the consensus level, which adjusts both the preference values and the self‐confidence levels. Finally, an example and some analyses are furnished to demonstrate the feasibility and effectiveness of the proposed method.
One aspect of improving communication is self-confidence and relationships between individuals. This research aims to determine the relationship between interpersonal communication and ...self-confidence in students at SMP Negeri 17 Palembang. This research is a quantitative correlational research with a research population of 272 and a research sample of 72 which was determined using a simple random sampling technique using the Slovin formula. The data collection technique in this research uses a psychological scale. The data collection method in this research is an interpersonal communication scale and a self-confidence scale obtained through direct distribution of instruments. Data analysis in this research used Pearson Product Moment. The results of data analysis show that the level of interpersonal communication is in the medium category with a percentage of 34% (25 students) and the level of self-confidence is in the low category with a percentage of 32% (23 students). Then the correlation coefficient (r) = 0.792 and sig. (2-tailed) 0.000 or > 0.05, which means there is a significant positive relationship between interpersonal communication and self-confidence. Thus, it can be concluded that there is a positive relationship between interpersonal communication and students' self-confidence at SMP Negeri 17 Palembang.
The notion that consumers' preference is constructed by decision context is well established. Two of such salient manifestations are compromise effect and attraction effect. Although literature has ...explored the moderators of these effects from the perspective of a decision maker, little is known about whether a significant difference exists between the effects of individual differences as a situational state and as a stable personality. This article approaches this question by examining how specific self‐confidence and general self‐confidence shape consumer's preference for context options. Four studies find that compromise effect is greater for consumer with high specific self‐confidence, whereas attraction effect is greater for consumer with low specific self‐confidence. The two context effects are greater for consumers with low general self‐confidence only in the presence of social influence. In addition, low (vs. high) general self‐confidence strengthens (vs. weakens) the impact of specific self‐confidence on context effects under this condition. This article concludes by discussing the theoretical and practical implications of the findings.
The pandemic has had a significant impact on education. Students' academic self-confidence has likely been affected as well. The transition to current onsite learning may have contributed to feelings ...of anxiety and decreased their self-confidence. This study aimed to measure student’s academic self-confidence and its impact on their English learning process. It was a descriptive research design with quantitative questionnaires distributed to 100 male and female students of Islamic broadcasting communication study program of IAIN Kediri. The result revealed that few students had low academic self-confidence when they had to argue in English with their classmates. Most students had high academic self-confidence to carry out other activities in the class and outside the class in finding English learning goals. Furthermore, students’ academic self-confidence highly affects their autonomous learning so that makes students able to work and learn English independently by using computers and the internet. It makes learning English more enjoyable for them as well. In addition, most of the students agreed that their self-confidence caused them to make regular plans to review English lessons, actively participate in English learning, ask English-related questions to classmates and lecturers, to share ideas and opinions in English group discussions, and also do English presentations well. The results of this study can be a consideration for English teachers to pay more attention to students who still have low confidence by applying teaching strategies that increase students' self-confidence.
Self-confidence is a trait that can evoke an attitude to have positive, idealistic, and optimistic thoughts about abilities. Even though there are frequent interactions between teachers and students ...with English in class, students still feel less confident when speaking in front of their classmates. The study was aimed to investigate the relationship between EFL students' self-confidence and their speaking skills at SMPIT Al Muchtar. The type of this study is quantitative design. The IBM SPSS Statistics application with 24 version was used to calculate. The population taken was all the eighth grade students which consisted of 108 students. There were 30 students taken using the purposive sampling technique as the respondents comprising 22 females and 8 males. Two instruments were used to collect the data, namely: a questionnaire for measuring students’ self-confidence and speaking test used for speaking skills. After the data was obtained, the researcher analyzed the correlation data. It was found that there was a positive relationship between EFL students' self-confidence and speaking skills at SMPIT Al Muchtar. This proved that Ha was accepted and Ho was rejected because 0.548 > 0.361 with a significance value of 5%. In conclusion, there was a fairly significant relationship between self-confidence and speaking skill.
We all have certain styles of behavior and ways of relating to other people. Some of us are ordinary types, others are careless. The purpose of this study is to analyze the personality constructs ...according to Carl Gustav Jung, namely Persona and Shadow, the problem formulation is seen based on the personality of white Muslim teenagers who wear hijab, whether as an identity or just a trend. Some of us prefer to do our own work, others are more social. The method in this research is literature study sourced from journals, books, and other sources. Some of us are followers, others are leaders. Some of us appear immune to the attacks of others, while others avoid social initiatives for fear of disappointment. When a pattern of behavior becomes so inflexible or maladaptive that it causes significant personal impairment or interferes with social and occupational functioning, it may be diagnosed as a personality disorder.
Aim

Review Methods
This review was conducted according to the recommendations of Cochrane Handbook for Systematic Reviews and reported according to the PRISMA Statement. Experimental and quasi‐experimental studies that compared the effect of simulation on stress, anxiety and self‐confidence of nursing students were included. The selection of studies and data extraction was performed independently by two reviewers. Simulation information was collected as prebriefing, scenario, debriefing, duration, modality, fidelity and simulator. Data summarization was performed by qualitative synthesis and meta‐analytical methods.
Results
Eighty studies were included in the review, and most reported in detail the structure of the simulation, contemplating prebriefing, scenario, debriefing and the duration of each step. In subgroup meta‐analysis, the presence of prebriefing, duration of more than 60 min and high‐fidelity simulations helped reduce anxiety, while the presence of prebriefing and debriefing, duration, immersive clinical simulation modalities and procedure simulation, high‐fidelity simulations and use of mannequins, standardised patients and virtual simulators, contributed to greater students' self‐confidence.
Conclusions
Different modulations of simulation design components imply reduction of anxiety and increased self‐confidence in nursing students, especially highlighting the quality of the methodological report of simulation interventions.
Relevance to Clinical Practice

Objectives
The aim of this study was to develop and evaluate the effect of a manual dexterity training program on manual dexterity, perception of self‐confidence, quality of cavity preparations, and ...ergonomic work posture of dental students prior to preclinical training.
Methods
Students in the first year of the undergraduate dentistry program (N = 63) participated in this study. The program consisted of eight phases in which students performed different types of activities. The dependent variables were: manual dexterity assessed by the modified Dental Manual Dexterity Assessment; self‐confidence to perform a preclinical procedure using the VAS scale; quality of Class I cavity preparation; angular deviation from the neutral position of the neck, trunk, wrist and distance between the student's eyes and the mannequin's tooth. These variables were evaluated at two different times: before and after the application of the program. The independent variable was the preclinical manual dexterity training program. After meeting the assumption of normality, the paired t‐Student test was performed, the significance level was 5%.
Results
The results showed a statistically significant difference in relation to manual dexterity (p < 0.001), self‐confidence (p < 0.001), quality of cavity preparations (p < 0.001), distance from the eyes of the student/mannequin (p < 0.001), deviation angle of the neutral position of the trunk (p = 0.007) and wrists (p < 0.001), with better results in posttraining.
Conclusion
It was possible to conclude that, in general, the proposed training positively influenced the self‐confidence, dexterity, quality of work, and ergonomics of the evaluated students.
Little is known about health variables and if these variables could increase the risk of injuries among adolescent elite athletes. The primary aim was to present overall data on self‐perceived ...stress, nutrition intake, self‐esteem, and sleep, as well as gender and age differences, on two occasions among adolescent elite athletes. A secondary aim was to study these health variables as potential risk factors on injury incidence. A questionnaire was e‐mailed to 340 adolescent elite athletes on two occasions during a single school year: autumn semester and spring semester. The results show that during autumn semester, the recommended intake of fruits, vegetables, and fish was not met for 20%, 39%, and 43% of the adolescent elite athletes, respectively. The recommended amount of sleep during weekdays was not obtained by 19%. Multiple logistic regression showed that athletes sleeping more than 8 h of sleep during weekdays reduced the odds of injury with 61% (OR, 0.39; 95% CI, 0.16–0.99) and athletes reaching the recommended nutrition intake reduced the odds with 64% (OR, 0.36; 95% CI, 0.14–0.91). Our findings suggest that nutrition intake and sleep volume are of importance in understanding injury incidence.
