Objective Otologic diseases are common in all age groups and can significantly impair the function of this important sensory organ. To make a correct diagnosis, the correct handling of the otoscope and a correctly performed examination are essential. A virtual reality simulator could make it easier to teach this difficult-to-teach skill. The aim of this study was to assess the face, content, and construct validity of the novel virtual reality otoscopy simulator and the applicability to otologic training. Study Design Face and content validity was assessed with a questionnaire. Construct validity was assessed in a prospectively designed controlled trial. Setting Training for medical students at a tertiary referral center. Method The questionnaire used a 6-point Likert scale. The otoscopy was rated with a modified Objective Structured Assessment of Technical Skills. Time to complete the task and the percentage of the assessed eardrum surface were recorded. Results The realism of the simulator and the applicability to medical training were assessed across several items. The ratings suggested good face and content validity as well as usefulness and functionality of the simulator. The otolaryngologists significantly outperformed the student group in all categories measured (P < .0001), suggesting construct validity of the simulator. Conclusion In this study, we could demonstrate face, content, and construct validity for a novel high-fidelity virtual reality otoscopy simulator. The results encourage the use of the otoscopy simulator as a complementary tool to traditional teaching methods in a curriculum for medical students.

The Impact

BACKGROUND: Successful shared decision making (SDM) in clinical practice requires that future clinicians learn to appreciate the value of patient participation as early as in their medical training. Narratives, such as patient testimonials, have been successfully used to support patients’ decision-making process. Previous research suggests that narratives may also be used for increasing clinicians’ empathy and responsiveness in medical consultations. However, so far, no studies have investigated the benefits of narratives for conveying the relevance of SDM to medical students.METHODS: In this randomized controlled experiment, N = 167 medical students were put into a scenario where they prepared for medical consultation with a patient having Parkinson disease. After receiving general information, participants read either a narrative patient testimonial or a fact-based information text. We measured their perceptions of SDM, their control preferences (i.e., their priorities as to who should make the decision), and the time they intended to spend for the consultation.RESULTS: Participants in the narrative patient testimonial condition referred more strongly to the patient as the one who should make decisions than participants who read the information text. Participants who read the patient narrative also considered SDM in situations with more than one treatment option to be more important than participants in the information text condition. There were no group differences regarding their control preferences. Participants who read the patient testimonial indicated that they would schedule more time for the consultation.CONCLUSIONS: These findings show that narratives can potentially be useful for imparting the relevance of SDM and patient-centered values to medical students. We discuss possible causes of this effect and implications for training and future research.

Objective. To assess the face, content, and construct validity of the Voxel-Man TempoSurg Virtual Reality simulator. Participants and Methods. 74 ear, nose, and throat (ENT) surgeons participated. They were assigned to one of two groups according to their level of expertise: the expert group (n=16) and the novice group (n=58). The participants performed four temporal bone dissection tasks on the simulator. Performances were assessed by a global score and then compared to assess the construct validity of the simulator. Finally, the expert group assessed the face and content validity by means of a five-point Likert-type scale. Results. experienced surgeons performed better (p<.01) and faster (p<.001) than the novices. However, the groups did not differ in terms of bone volume removed (p=.11) or number of injuries (p=.37). 93.7% of experienced surgeons stated they would recommend this simulator for anatomical learning. Most (87.5%) also thought that it could be integrated into surgical training. Conclusion. The Voxel-Man TempoSurg Virtual Reality simulator constitutes an interesting complementary tool to traditional teaching methods for training in otologic surgery.

3D Printed

Intra-articular injections are routinely performed to alleviate pain and inflammation associated with osteoarthritis in horses. Intra-articular injections require accurate needle placement to optimize clinical outcomes and minimize complications. This study’s objectives were to develop and validate a three-dimensional (3D) printed model of an equine cervical articular process joint to teach ultrasound-guided injections. Five identical models of an equine cervical articular process joint were 3D printed and embedded in 10% ballistic gelatin. Experts’ and novices’ ability to successfully insert a needle into the joint space of the model using ultrasound guidance was assessed and graded using an objective structured clinical examination (OSCE). Scores from experts and novices were compared to evaluate the construct validity of the model. Participants also answered a survey assessing the face and content validity of the model. Experts required less time (22.51 seconds) for correct needle placement into the model joint space than novices (35.96 seconds); however, this difference was not significant ( p = .53). Experts’ median total OSCE score (14) was significantly higher ( p = .03) than novices’ (12), supporting the model’s construct validity. Participants agreed on the face and content validity of the model by grading all survey questions greater than 7 on a 10-point Likert-type scale. In summary, we successfully developed a 3D printed model of an equine cervical articular process joint, partially demonstrated the construct validity of the model, and proved the face and content validity of this new training tool.

Abstract Background: Childbirth preparation classes can reduce pregnant women’s anxiety and fear levels by providing them with training supports. The importance of mothers’ participation in these classes, evaluation of their satisfaction with these classes, and lack of a standard instrument in Iran led to the necessity of conducting this study for the translation and psychometric analysis of the women’s satisfaction with the childbirth education class questionnaire for the population of Iranian women. Methods: The questionnaire was translated from English into Persian through the forward-backward translation method. The cluster sampling method was employed to select 205 pregnant women with gestational age of 35-37 weeks from all health complexes of Tabriz, Iran. The face, content, and construct validity of the research instrument were assessed through exploratory and confirmatory factor analyses. Internal consistency and test-retest reliability were measured to evaluate the overall reliability of the questionnaire. Results: The impact scores of all items were above 1.5. The content validity index (CVI) and content validity ratio (CVR) of the questionnaire were 0.88 and 0.94, respectively. The convergent construct validity of the whole questionnaire and those of its three subscales were confirmed through the exploratory factor analysis (EFA). The factor loadings of no items were below 0.3, and the X2⁄df ratio was smaller than 5. In addition, the RMSEA was smaller than 0.08; therefore, the overall model validity was confirmed. Cronbach’s alpha and intra-class correlation coefficient (ICC) were 0.93 and 0.96, respectively, indicating the acceptable reliability of the questionnaire. Conclusion: The Persian version of this questionnaire, entitled "Women’s Satisfaction with Childbirth Education Class" is a valid and reliable instrument for measuring Iranian women’s satisfaction with childbirth education classes.

Purpose: We developed a virtual reality (VR) endotracheal intubation training that applied 2 interaction modalities (hand-tracking or controllersIt aimed to investigatedthe differences of usuability between using hand tracking and controllers during the VR intervention for intubation training for medical students from February 2021 to March 2021 in Thailand.Methods: Forty-five participants were divided into 3 groups: video only, video with VR controller training, and video with VR hand tracking training. Pre-test, post-test, and practice scores were used to assess learning outcomes. The System Usability Scale (SUS) and User Satisfaction Evaluation Questionnaire (USEQ) questionnaires were used to evaluate the differences between the VR groups. The sample comprised 45 medical students (undergraduate) who were taking part in clinical training at Walailak University in Thailand.Results: The overall learning outcomes of both VR groups were better than those of the video group. The post-test scores (P=0.581) and practice scores (P=0.168) of both VR groups were not significantly different. Similarly, no significant between-group differences were found in the SUS scores (P=0.588) or in any aspects of the USEQ scores.Conclusion: VR enhanced medical training. Interactions using hand tracking or controllers were not significantly different in terms of the outcomes measured in this study. The results and interviews provided a better understanding of support learning and training, which will be further improved and developed to create a self-learning VR medical training system in the future.

Introduction: Simulation-based training is used to help trainees learn surgical procedures in a safe environment. The objective of our study was to test the face, content, and construct validity of the transurethral resection of bladder tumor (TURBT) module built on the Simbionix TURP Mentor simulator. Methods: Participants performed five standardized cases on the simulator. Domains of the simulator were evaluated on a five-point Likert scale to establish face and content validity. Construct validity was assessed through the simulator's built-in scoring metrics, as well as video recordings of the simulator screen and an anonymized view of participants' hands and feet, which were evaluated using an objective structured assessment of technical skills (OSATS) tool. Results: Ten experienced operators and 15 novices participated. Face validity was somewhat acceptable (mean realism 3.8/5±1.03 standard deviation [SD]; mean appearance 4.1/5±0.57), as was content validity, represented by simulation of key steps (mean 3.9±0.57). The simulator failed to achieve construct validity. There was no difference in mean simulator scores or OSATS scoring between experienced operators and novices. Novices significantly improved their mean simulator scores (305.9 vs. 332.4, p=0.006) and OSATS scoring (15.8 vs. 18.1, p=0.001), while 87% felt their confidence to perform TURBT improved. Overall, 92% of participants agreed that the simulator should be incorporated into residency training. Conclusions: Our study suggests a role for the TURBT module of the Simbionix TURP Mentor simulator as an introduction to TURBT for urology trainees. Strong support was found from both experienced operators and novices for its formal inclusion in resident education.

ABSTRACT Objective: To validate the evaluation questionnaire on adherence of chronic kidney disease (CKD) patients under hemodialysis. Method: We verified the following psychometric properties of the instrument: reliability (stability and internal consistency) and validity (face, content, and construct). Results: The intraclass correlation coefficient reached a value of 0.98 for the adherence questions and 0.91 for the perception questions. Regarding the kappa of the 14 questions examined, 12 had a value > 0.8, whereas the Cronbach's alpha had a value of 0.57. Experts ensured the face and content validity of the instrument, giving it an overall content validity index of 0.96. Construct validity, analyzed by Mann-Whitney test, was achieved as all domains showed a significant association with p<0.01. Conclusion: We verified, by the presented results, that the instrument has been validated for use in Brazil.
