The role of the genetic testing industry in patient education of hereditary cancer: An observational study assessing the quality of patient education videos.

OBJECTIVES: Genetic testing (GT) companies have developed patient education videos to supplement or replace pre-test genetic counseling (GC) by certified genetic counselors (CGC). The aim of this study was to assess the quality of these videos compared to the standard of care (SOC). METHODS: Videos from four major GT companies were selected from an internet search identifying pre-test patient education videos. A scoring rubric with 22 questions and 36 total points was devised to assess quality metrics, as described by the National Cancer Institute and National Society of Genetic Counselors. Twenty-two individuals with varying genetics expertise (3 gynecologic oncologists, 3 academic generalists, 4 CGC, a genetics community health worker, 3 cancer care navigators, and 8 medical students) scored each video. Scorers were blinded to others' assessments. RESULTS: Invitae had the highest median score (26/36), followed by Myriad (22/36), Ambry (17.5/36), and Color (15/36). All videos scored highly in explaining DNA basics, cancer development, and hereditary cancer predisposition. All addressed benefits of GT but failed to address potential disadvantages. All scored poorly in explaining medical terms and different GT options. There was variability in addressing patient concerns including cost, privacy, and procedure. CONCLUSIONS: There is significant variation in the content of pre-test patient education videos between GT companies. None of the videos met the SOC for pre-test GC, and none addressed disadvantages of GT, possibly due to a conflict of interest. With improvement in content, accessibility, and use of interactive platforms, these videos may serve as an adjunct to in-person pre-test GC.

Standardized Surgical Video Curriculum for Teaching Residents Principles of Abdominal Hysterectomy.

OBJECTIVES: To evaluate whether an institutionally created video-based educational module will improve obstetrics and gynecology residents' understanding of surgical anatomy and principles for performing abdominal hysterectomy. Secondary aims included evaluating the trainees' confidence levels and perceptions before and after the educational experience and ultimately implementing the module into the program curriculum, if successful. METHODS: In this prospective study, postgraduate obstetrics and gynecology resident physicians (n = 27) at the McGaw Medical Center of Northwestern University were assigned to watch an institutionally created video-based educational module on abdominal hysterectomy before the start of their gynecologic oncology rotation. A knowledge assessment and a postmodule survey were given to participants immediately following the module and repeated at the end of the 4-week rotation. RESULTS: Participants reported a median rating of 4 (n = 21, interquartile range 4-4) on a 5-point Likert scale when asked to rate the quality of the module. The module also was rated as equally effective both immediately after watching the module and after completing their gynecologic oncology rotation (median 4, interquartile range 3-4 at both times; p = 0.299, Wilcoxon signed rank test). Overall trends revealed that the video module had a greater impact on knowledge of surgical anatomy than on self-reported surgical skills and that postgraduate year 2 and postgraduate year 3 residents benefited more from the intervention. CONCLUSIONS: A video module can be a high-quality and effective educational tool for teaching the surgical principles, anatomy, and steps to perform abdominal hysterectomy to obstetrics and gynecology residents.

Lessons learned from the implementation of a video health coaching technology intervention to improve self-care of family caregivers of adults with heart failure.

Individuals with heart failure (HF) typically live in the community and are cared for at home by family caregivers. These caregivers often lack supportive services and the time to access those services when available. Technology can play a role in conveniently bringing needed support to these caregivers. The purpose of this article is to describe the implementation of a virtual health coaching intervention with caregivers of HF patients ("Virtual Caregiver Coach for You"-ViCCY). A randomized controlled trial is currently in progress to test the efficacy of the intervention to improve self-care. In this trial, 250 caregivers will be randomly assigned to receive health information via a tablet computer (hereafter, tablet) plus 10 live health coaching sessions delivered virtually (intervention group; n = 125) or health information via a tablet only (control group; n = 125). Each tablet has specific health information websites preloaded. To inform others embarking on similar technology projects, here we highlight the technology challenges encountered with the first 15 caregivers who received the ViCCY intervention and the solutions used to overcome those challenges. Several adaptations to the implementation of ViCCY were needed to address hardware, software, and network connectivity challenges. Even with a well-designed research implementation plan, it is important to re-examine strategies at every step to solve implementation barriers and maximize fidelity to the intervention. Researcher and interventionist flexibility in adapting to new strategies is essential when implementing a technology-based virtual health coaching intervention.

A Qualitative Analysis of Ostomy-Related Patient Education Videos on YouTube.

OBJECTIVE: To analyze the content, reliability, and quality of the most viewed YouTube videos targeting patients with ostomies intending to learn about ostomy care (OC). METHODS: Using the keywords "stoma care," "colostomy care," and "ileostomy care," researchers assessed the publicly visible English-language ostomy patient education videos available on YouTube. A total of 84 videos were independently analyzed by two physicians experienced in OC. Data on video characteristics, source, content, reliability, and quality were collected and recorded for each video separately. RESULTS: Of the 84 videos analyzed, 49 were classified as useful (58.33%) and 35 as misleading (41.66%). There were statistically significant differences between the groups in terms of the time elapsed since upload (P < .017), reliability (P < .001), comprehensiveness (P < .001), Global Quality Scale scores (P < .001), source (P < .001), and lecturer types (P < .011). The reliability, comprehensiveness, and Global Quality Scale scores were statistically higher for videos uploaded by universities, professional healthcare communities, and nonprofit physicians (P < .001). However, the popularity of the OC videos posted on YouTube was not related to their reliability, comprehensiveness, or quality. CONCLUSIONS: The open-access nature of the YouTube platform may impair patient education video quality and accuracy. YouTube may be an additional educational tool for OC, but clinicians need to be familiar with specific and reliable resources to guide and educate new patients with ostomies to achieve the best outcomes.

Comparisons of the Effects of Watching Virtual Reality Videos and Chewing Gum on the Length of Delivery Stages and Maternal Childbirth Satisfaction: A Randomized Controlled Trial.

Background: Maternal childbirth satisfaction is one of the important indicators of the quality of the care provided. The use of non-pharmacological therapies can make the childbirth process a pleasurable event for the mother. This study aimed to compare the effects of watching virtual reality videos and chewing gum on the length of delivery stages and maternal satisfaction. Methods: This clinical trial study was performed on 93 women with first and second pregnancies, who were referred to Allameh Bohlool Hospital in Gonabad and Sajjadieh Hospital in Torbat-e-Jam, Iran, for childbirth between 2018 and 2019. Pregnant women were randomly assigned to three groups of chewing gum, virtual reality, and control. Interventions were performed twice: in the active (dilation of 4-5 cm) and second (dilation of 7-8 cm) phases of parturition for 20 minutes each. Data were collected using data-gathering forms, including a demographic characteristics form, a midwifery characteristics form, and the Mackey Childbirth Satisfaction Rating Scale. The data were analyzed using SPSS, version 22, via the Chi square tests, ANOVA, Kruskal-Wallis, and Tukey's post hoc tests. Results: The difference in the mean maternal childbirth satisfaction score between the two intervention groups of virtual reality and chewing gum was not statistically significant (P=0.339), but the mean score in the intervention groups was higher than that of the control group (P<0.001(. There was no significant difference in the mean length of the active and second phases of parturition between the two intervention groups, but this value in the intervention groups was significantly lower than that of the control group. Conclusion: The thought divergence interventions of chewing gum and watching virtual reality videos enhanced childbirth satisfaction, and curtailed parturition stages in our sample of pregnant women. Trial Registration Number: IRCT20181214041963N1.

Patient Perceptions of Video Visits Using Veterans Affairs Telehealth Tablets: Survey Study.

BACKGROUND: Video-based health care can help address access gaps for patients and is rapidly being offered by health care organizations. However, patients who lack access to technology may be left behind in these initiatives. In 2016, the US Department of Veterans Affairs (VA) began distributing video-enabled tablets to provide video visits to veterans with health care access barriers. OBJECTIVE: This study aimed to evaluate veterans' experiences with VA-issued tablets and identify patient characteristics associated with preferences for video visits vs in-person care. METHODS: A baseline survey was sent to the tablet recipients, and a follow-up survey was sent to the respondents 3 to 6 months later. Multivariate logistic regression was used to identify patient characteristics associated with preferences for care, and we examined qualitative themes around care preferences using standard content analysis methods for coding the data collected in the open-ended questions. RESULTS: Patient-reported access barriers centered around transportation and health-related challenges, outside commitments, and feeling uncomfortable or uneasy at the VA. Satisfaction with the tablet program was high, and in the follow-up survey, approximately two-thirds of tablet recipients preferred care via a tablet (194/604, 32.1%) or expressed that video-based and in-person care were "about the same" (216/604, 35.7%), whereas one-third (192/604, 31.7%) indicated a preference for in-person care. Patients were significantly more likely to report a preference for video visits (vs a preference for in-person visits or rating them "about the same") if they felt uncomfortable in a VA setting, reported a collaborative communication style with their doctor, had a substance use disorder diagnosis, or lived in a place with better broadband coverage. Patients were less likely to report a preference for video visits if they had more chronic conditions. Qualitative analyses identified four themes related to preferences for video-based care: perceived improvements in access to care, perceived differential quality of care, feasibility of obtaining necessary care, and technology-related challenges. CONCLUSIONS: Many recipients of VA-issued tablets report that video care is equivalent to or preferred to in-person care. Results may inform efforts to identify good candidates for virtual care and interventions to support individuals who experience technical challenges.

Implementing Follow-Along Physical Activity Videos with People Living With Chronic Conditions: A Feasibility Study.

BACKGROUND: Compelling evidence supports multiple benefits of physical activity (PA) even in small bursts. Less than 50% of Americans achieve recommended PA levels, lower still for individuals living with chronic illness or disease. PURPOSE: The purpose of this study was to develop and evaluate the feasibility and preliminary effects of 3-min follow-along video scenarios to promote brief episodes of low-moderate levels of PA among individuals with chronic diseases. METHODS: Guided by our previous studies and self-efficacy theory, the program (WellMe in 3© for Patients) was modeled after another program developed for healthcare staff. An advisory panel and a health and fitness expert guided the creation of twelve 3-min video scenarios that included two individuals living with chronic illness and a fitness leader who guided the PA scenarios and how to adapt them based on limitations. The 12 scenarios included 3 min of aerobic activities, stretching, or balance. Preliminary pilot effects were measured among 39 patients living with chronic conditions for one month. Standardized instruments were used to measure PA levels, PA self-efficacy (SE), and quality of life (QoL); usability and satisfaction were assessed using researcher-developed tools. Descriptive and inferential statistics were used to evaluate change over time. RESULTS: Twelve video scenarios were created tailored to persons with chronic illness. Thirty-nine participants piloted the program, reporting an average of two chronic conditions. Baseline QoL scores were lower than normative data, self-efficacy scores were low-to-moderate, and PA levels were very low. Participants averaged using one video per day. 62% of participants provided complete self-reported pre- and post-QoL and SE data and 41% provided pre- and post-PA (accelerometer) data. Significant improvements were found for general health and energy scores, and trends were found for self-efficacy scores. PA levels were highly variable with nonsignificant increases from baseline. Effect sizes were low-moderate for several measures. About 79% of participants rated program "Very good"; all recommended the program. LINKING EVIDENCE TO ACTION: Physical activity has multiple health benefits for all people including those living with chronic conditions. Even short bouts of physical activity have health benefits. A program of 3-min follow-along PA videoclips for individuals living with chronic disease holds promise for clinicians and researchers.

Is perception of quality more important than technical quality in patient video cases?

BACKGROUND: The use of video cases to demonstrate key signs and symptoms in patients (patient video cases or PVCs) is a rapidly expanding field. The aims of this study were to evaluate whether the technical quality, or judgement of quality, of a video clip influences a paediatrician's judgment on acuity of the case and assess the relationship between perception of quality and the technical quality of a selection of video clips. METHODS: Participants (12 senior consultant paediatricians attending an examination workshop) individually categorised 28 PVCs into one of 3 possible acuities and then described the quality of the image seen. The PVCs had been converted into four different technical qualities (differing bit rates ranging from excellent to low quality). RESULTS: Participants' assessment of quality and the actual industry standard of the PVC were independent (333 distinct observations, spearmans rho = 0.0410, p = 0.4564). Agreement between actual acuity and participants' judgement was generally good at higher acuities but moderate at medium/low acuities of illness (overall correlation 0.664). Perception of the quality of the clip was related to correct assignment of acuity regardless of the technical quality of the clip (number of obs = 330, z = 2.07, p = 0.038). CONCLUSIONS: It is important to benchmark PVCs prior to use in learning resources as experts may not agree on the information within, or quality of, the clip. It appears, although PVCs may be beneficial in a pedagogical context, the perception of quality of clip may be an important determinant of an expert's decision making.

Legal drug content in music video programs shown on Australian television on saturday mornings.

AIMS: To examine the extent to which legal drug references (alcohol and tobacco) are present in the music video clips shown on two music video programs broadcast in Australia on Saturday mornings. Further, to examine the music genres in which the references appeared and the dominant messages associated with the references. METHODS: Music video clips shown on the music video programs 'Rage' (ABC TV) and [V] 'Music Video Chart' (Channel [V]) were viewed over 8 weeks from August 2011 to October 2011 and the number of clips containing verbal and/or visual drug references in each program was counted. The songs were classified by genre and the dominant messages associated with drug references were also classified and analysed. RESULTS: A considerable proportion of music videos (approximately one-third) contained drug references. Alcohol featured in 95% of the music videos that contained drug references. References to alcohol generally associated it with fun and humour, and alcohol and tobacco were both overwhelmingly presented in contexts that encouraged, rather than discouraged, their use. CONCLUSION: In Australia, Saturday morning is generally considered a children's television viewing timeslot, and several broadcaster Codes of Practice dictate that programs shown on Saturday mornings must be appropriate for viewing by audiences of all ages. Despite this, our findings show that music video programs aired on Saturday mornings contain a considerable level of drug-related content.

Remote sonographic interpretation: comparison of standardized video clips to still images.

OBJECTIVE: The aim of our study was to evaluate the role of standardized video clips compared with still images in the diagnostic accuracy of remote sonographic interpretation. METHODS: We compared the remote interpretation of sonographic examinations acquired with a standardized video clip approach to examinations performed with still images alone in 60 patients with various hepatic and extrahepatic pathologies. RESULTS: The use of video clips improved the diagnostic accuracy of sonographic studies interpreted remotely compared with the use of still images (p < 0.0001). The sensitivity, specificity, and positive and negative predictive values increased from 47.3% to 68.3%, 81.8% to 87.8%, 71.5% to 81%, and 63.8% to 74.5%, respectively. CONCLUSIONS: Standardized video clips are easy to obtain, less operator-dependent than still images, and can be transferred to remote sites without loss of important data. We recommend this method in remote interpretation (teleradiology and distant consultation) of sonographic examinations.

Validation of a new method for finding the rotational axes of the knee using both marker-based roentgen stereophotogrammetric analysis and 3D video-based motion analysis for kinematic measurements.

In a previous paper, we reported the virtual axis finder, which is a new method for finding the rotational axes of the knee. The virtual axis finder was validated through simulations that were subject to limitations. Hence, the objective of the present study was to perform a mechanical validation with two measurement modalities: 3D video-based motion analysis and marker-based roentgen stereophotogrammetric analysis (RSA). A two rotational axis mechanism was developed, which simulated internal-external (or longitudinal) and flexion-extension (FE) rotations. The actual axes of rotation were known with respect to motion analysis and RSA markers within ± 0.0006 deg and ± 0.036 mm and ± 0.0001 deg and ± 0.016 mm, respectively. The orientation and position root mean squared errors for identifying the longitudinal rotation (LR) and FE axes with video-based motion analysis (0.26 deg, 0.28 m, 0.36 deg, and 0.25 mm, respectively) were smaller than with RSA (1.04 deg, 0.84 mm, 0.82 deg, and 0.32 mm, respectively). The random error or precision in the orientation and position was significantly better (p=0.01 and p=0.02, respectively) in identifying the LR axis with video-based motion analysis (0.23 deg and 0.24 mm) than with RSA (0.95 deg and 0.76 mm). There was no significant difference in the bias errors between measurement modalities. In comparing the mechanical validations to virtual validations, the virtual validations produced comparable errors to those of the mechanical validation. The only significant difference between the errors of the mechanical and virtual validations was the precision in the position of the LR axis while simulating video-based motion analysis (0.24 mm and 0.78 mm, p=0.019). These results indicate that video-based motion analysis with the equipment used in this study is the superior measurement modality for use with the virtual axis finder but both measurement modalities produce satisfactory results. The lack of significant differences between validation techniques suggests that the virtual sensitivity analysis previously performed was appropriately modeled. Thus, the virtual axis finder can be applied with a thorough understanding of its errors in a variety of test conditions.

IVORY Guidelines (Instructional Videos in Otorhinolaryngology by YO-IFOS): A Consensus on Surgical Videos in Ear, Nose, and Throat.

OBJECTIVES/HYPOTHESIS: Otolaryngology instructional videos available online are often of poor quality. The objective of this article was to establish international consensus recommendations for the production of educational surgical videos in otolaryngology. STUDY DESIGN: DELPHI survey. METHODS: Twenty-seven international respondents participated in this study from 12 countries. Consensus was reached after three rounds of questionnaires following the Delphi methodology. The proposals having reached the 80% agreement threshold in the third round were retained. RESULTS: The main recommendations are as follows: 1) Ethics: patients must be anonymized and unrecognizable (apart from plastic surgery if necessary). A signed authorization must be obtained if the person is recognizable. 2) Technical aspects: videos should be edited and in high-definition (HD) quality if possible. Narration or subtitles and didactic illustrations are recommended. 3) Case presentation: name of pathology and procedure must be specified; the case should be presented with relevant workup. 4) Surgery: surgical procedures should be divided into several distinct stages and include tips and pitfalls. Pathology should be shown if relevant. Key points should be detailed at the end of the procedure. 5) Organ-specific: type of approach and bilateral audiometry should be specified in otology. Coronal plane computed tomography scans should be shown in endonasal surgery. It is recommended to show pre- and postoperative videos in voice surgery and preoperative drawings and photos of scars in plastic surgery, as well as the ventilation method in airway surgery. CONCLUSIONS: International recommendations have been determined to assist in the creation and standardization of educational surgical videos in otolaryngology and head and neck surgery. LEVEL OF EVIDENCE: 5 Laryngoscope, 131:E732-E737, 2021.

Evaluation of quality and reliability of YouTube videos on female urinary incontinence.

OBJECTIVES: Women often feel embarrassed about urinary incontinence, hesitate to see a doctor and search the internet to gain information on the disease. The objective of this study was to evaluate the quality of the most viewed YouTube™ pertaining to female urinary incontinence. MATERIAL AND METHODS: Sixty videos that met the inclusion criteria were assessed by two urologists through Quality Criteria for Consumer Health Information (DISCERN), Journal of the American Medical Association (JAMA) and Video Power Index (VPI) scoring systems. Videos' image type, video uploaders, general content, length, view counts, date of uploading, comment, like and dislike counts were also recorded and analyzed. RESULTS: Forty videos included real and 20 animation images. Nine videos were uploaded directly by physicians, 32 videos by health channels, 14 videos by hospital channels, 2 videos by herbalists and 3 videos by other sources. The mean comment, like and dislike counts of the videos were found as 49.4 ± 172.9, 642.5 ± 2,112.9 and 66.7 ± 192.4. The mean DISCERN score was found as 38.2 ± 11.5, JAMA score as 1.4 ± 0.6 and VPI score as 85.1 ± 12.1. There was no significant difference between physicians and non-physicians and between real and animated videos in terms of DISCERN and JAMA scores (p>0.05). CONCLUSIONS: The quality of the videos on YouTube™ pertaining to female urinary incontinence was at an average level. Healthcare professionals should be encouraged for uploading more accurate quality health related contents. Policy makers should develop policies for supervision of the videos uploaded on the internet.

Using a filming protocol to improve video-instructed cardiopulmonary resuscitation.

BACKGROUND: Video communications during cardiopulmonary resuscitation (CPR) can improve the quality of information exchange between a bystander performing CPR and an emergency medical dispatcher (EMD). OBJECTIVE: To improve chest compression effectiveness, a filming protocol instructing video camera placements around a patient was developed. This study measured whether the filming protocol increased chest compressions' effectiveness. METHODS: A simulation study was conducted comparing CPR effectiveness under three conditions: telephone-instructed, video-instructed, and video-instructed with the filming protocol. Twenty-five emergency medical technicians acted as EMDsin the three conditions. A mannequin measured five factors that determined the effectiveness of the chest compressions. RESULTS: Compared with telephone-instructed CPR, the filming protocol improved the proportion of time in which the bystander's hands were in the correct position during chest compressions. Compared with video-instructed CPR, the filming protocol improved both the proportion of time in which the chest was fully released after each compression and the proportion of time in which the compressions were conducted with an appropriate rhythm. The depth and rate of compressions did not improve in the filming protocol condition. CONCLUSIONS: Video-instructed CPR with the filming protocol improves CPR effectiveness compared to telephone- and video-instructed CPR. Detailed implementation can improve new technology introduction.

Educating Students About Opioid Use Disorder and Treatments in the Community Using an Educational Video.

BACKGROUND: A treatment gap exists for people in the community with opioid use disorders (OUDs). Stigma and lack of knowledge of how to access community resources contribute to this gap. One valuable resource that may help fill this gap is nursing students. PURPOSE: This study examined the impact of an educational video on prelicensure and postlicensure nursing students' knowledge and attitudes toward people with OUD. METHODS: A pre-post study design was used to examine whether 406 nursing students' knowledge and attitudes changed after viewing an educational video. Knowledge and attitudes were measured by an online survey, consisting of demographics, an 8-item Knowledge and Attitudes survey, and the Drug and Drug Problems Perceptions Questionnaire. RESULTS: The educational video produced a statistically significant positive improvement on nursing students' knowledge and attitudes. CONCLUSION: Educating nursing students about OUD and treatment options can help reduce stigma and improve care toward people with OUD.

Pilot Study of Videos to Deliver Mindfulness-Based Art Therapy for Adults With Multiple Sclerosis.

BACKGROUND: Mindfulness-based art therapy (MBAT) has been shown to provide a strategy for adults with multiple sclerosis (MS) to self-manage their symptoms. There is a need for the use of an MBAT intervention that can be delivered in any setting for adults with MS. The purpose of this pilot feasibility study was to test the feasibility and acceptability of an MBAT intervention delivered via videoconference. METHODS: We developed an MBAT intervention to be delivered by videoconference to adults with MS recruited from an academic center registry. We also conducted phone interviews to collect acceptability data. RESULTS: Most of the participants (n = 5) were very positive about the MBAT video sessions and stated content as clear and easy to follow and understand. The time and delivering method were acceptable. CONCLUSION: Mindfulness-based art therapy sessions delivered through videoconference are acceptable and feasible for adults with MS.

Evaluation of the reliability, utility, and quality of the information in cardiopulmonary resuscitation videos shared on Open access video sharing platform YouTube.

BACKGROUND: The internet is a widely used source for obtaining medical information both by patients and physicians. YouTube is an essential source of information that may be a useful tool to inform the public and may improve the learning experience if used adequately. In this study, we aimed to estimate the quality and accuracy of videos about cardiopulmonary resuscitation videos aired on YouTube, which is the most popular video platform of the online world. METHODS: We included the first 100 videos, in English, returned by the YouTube search engine in response to "cardiopulmonary resuscitation" keyword query to the study. The popularity of the videos was evaluated with an index called the video power index. The educational quality, accuracy, and transparency of the visual content were measured using the DISCERN questionnaire (DISCERN), Journal of American Medical Association (JAMA-BC) benchmark criteria, and Global Quality Score (GQS). The technical quality was measured by the Cardiopulmonary Resuscitation Scoring System (CPR-SS), which was utilized by three bariatric surgeons. RESULTS: The source in 7% of the videos was medical doctors. The content in 89% of the videos was cardiopulmonary resuscitation technique. According to sources, videos uploaded by physicians had significantly higher quality, transparency, educational and technical value. Unlike, videos uploaded by physicians had a lower video power index than videos uploaded by non-medical professionals. Cardiopulmonary resuscitation technique videos had significantly higher quality, transparency, educational and technical value. Cardiopulmonary resuscitation technique videos also had higher popularity scores than "information or lecture" videos. Also, negative correlations were found between the (popularity index and transparency, education and technical quality scores. CONCLUSIONS: Online information on cardiopulmonary resuscitation is of low quality, and its contents are of unknown source and accuracy. However, the educational potential of the online video platform, YouTube, cannot be neglected.

Evaluation of a Cognitive-Behavioral Game Design-Based Mobile Game on Alcohol Use for Adolescents.

Objective: Determine the effectiveness of a cognitive behavioral game design (CBGD) based mobile game as an alcohol use intervention. Materials and Methods: Experimental design with 140 participants randomly assigned to either play a mobile game (n = 69) or watch a video documentary (n = 71). Results: Both groups displayed a decrease in intent to use and an increase in knowledge. The video intervention was superior in affecting actual use. Conclusion: Mobile game affects intent to use and is superior to the video in affecting knowledge.

Concise evaluation of decision aids.

OBJECTIVE: Decision aids purport to help patients make treatment related choices. Several instruments exist to evaluate decision aids. Our aim is to compare the responsiveness of several instruments. METHODS: Two different decision aids were randomized in patients at high risk for breast and ovarian cancer. Treatment choices were between prophylactic surgery and screening. Effect sizes were calculated to compare the responsiveness of the measures. RESULTS: One decision aid was randomized in 390 women, the other in 91 ensuing mutation carriers. Three factors were identified related to Information, Well-being and Decision Making. Within each factor, single item measures were as responsive as multi-item measures. CONCLUSION: Four single items, 'the amount of information received for decision making,' 'strength of preference,' 'I weighed the pros and cons,' and 'General Health,' were adequately responsive to the decision aids. PRACTICE IMPLICATIONS: These items might be considered for inclusion in questionnaires to evaluate decision aids.
