RESUMEN

BACKGROUND: Children with congenital heart disease (CHD) who undergo open-heart surgery are at risk of developmental impairment, including motor delay, which contributes to parental concerns. Additionally, parents experience prolonged stress associated with their child's disease. There is a lack of early motor interventions in infants with CHD accounting for parental burdens. We developed a family-tailored early motor intervention (EMI-Heart), aiming to promote motor development in infants with CHD and family well-being. The primary aim was to evaluate the feasibility of the study design and the intervention. The secondary aim was to evaluate differences between the intervention and the control group in motor outcomes and family well-being at baseline (3-5 months), post-treatment (6-8 months), and at follow-up (12 months). METHOD: In this single-centre feasibility randomized control trial (RCT), infants with CHD after open-heart surgery without genetic or major neurological comorbidities were randomly allocated to EMI-Heart or the control group (standard of care). EMI-Heart's key elements promote postural functional activities and encourage parental sensitivity to infants' motor and behaviour cues. Infants assigned to EMI-Heart received nine sessions of early motor intervention at home, in the hospital, and online for a duration of 3 months by a paediatric physiotherapist. We performed descriptive statistics for feasibility and secondary outcomes. RESULTS: The recruitment rate was 59% (10/17), all participating families completed the study (10/10), and the intervention duration was 3.9 months (± 0.54), including nine intervention sessions per family. Median acceptability to parents was 3.9 (1 = not agree-4 = totally agree, Likert scale). The paediatric physiotherapist considered the intervention as feasible. The comparison of motor outcomes did not show differences between groups. However, we detected improved reliable change scores in family well-being outcomes for families of the intervention group compared to the controls. CONCLUSIONS: Our research indicates that EMI-Heart is a feasible intervention for infants with CHD after open-heart surgery. The intervention was highly acceptable both to parents and to the paediatric physiotherapist. Online treatment sessions offer a valuable alternative to home and hospital visits. This feasibility RCT provides a foundation for a future full trial. TRIAL REGISTRATION: ClinicalTrials.gov, NCTT04666857. Registered 23.11.2020.

RESUMEN

BACKGROUND: Effective cardiopulmonary resuscitation (CPR) training for nursing students is crucial for improving patient outcomes in cardiac arrest scenarios. This study assesses the impact of infographic versus video feedback on enhancing nursing students' clinical skills in Basic Life Support (BLS). METHODS: In a randomized controlled setting, 76 nursing students at Torbat Heydariyeh University of Medical Sciences were divided into two groups: one received infographic-based education and the other video feedback training. Pre- and post-intervention assessments measured knowledge and skill retention using validated questionnaires. RESULTS: Post-training, the infographic group showed significantly higher knowledge scores, while the video feedback group exhibited greater improvement in CPR skill performance. No significant differences were noted in pre-training assessment scores between the groups. CONCLUSION: Infographic-based education enhances BLS knowledge retention, and video feedback improves practical CPR skills. This suggests potential benefits of a combined infographic and video feedback approach for optimizing CPR training outcomes, addressing a critical need in medical education.

RESUMEN

Modern medical training consists largely of lecture-based instruction and in vivo or video modeling of specific skills. Other instructional methods, such as teaching with acoustical guidance (TAGteach), have rarely been evaluated. In this study, we compared teaching with tactile guidance, or tactile TAGteach in which a vibratory stimulus is delivered to indicate a correct response, with video modeling and self-evaluative video feedback to teach four participants two medical skills: simple interrupted suture and endotracheal intubation. The results showed that both instructional methods improved performance. However, three participants met the mastery criterion in the tactile TAGteach condition first, although this instructional method required more time to train the skills. We discuss the implications of these findings for training skills to medical practitioners.

RESUMEN

BACKGROUND: Video-feedback observational therapy (VOT) is an intensive rehabilitation technique based on movement repetition and visualization that has shown benefits for motor rehabilitation of the upper and lower limbs. Despite an increase in recent literature on the neurophysiological effects of VOT in the upper limb, there is little knowledge about the cortical effects of visual feedback therapies when applied to the lower limbs. The aim of our study was to better understand the neurophysiological effects of VOT. Thus, we identified and compared the EEG biomarkers of healthy subjects undergoing lower limb VOT during three tasks: passive observation, observation and motor imagery, observation and motor execution. METHODS: We recruited 38 healthy volunteers and monitored their EEG activity while they performed a right ankle dorsiflexion task in the VOT. Three graded motor tasks associated with action observation were tested: action observation alone (O), motor imagery with action observation (OI), and motor execution synchronized with action observation (OM). The alpha and beta event-related desynchronization (ERD) and event-related synchronization (or beta rebound, ERS) rhythms were used as biomarkers of cortical activation and compared between conditions with a permutation test. Changes in connectivity during the task were computed with phase locking value (PLV). RESULTS: During the task, in the alpha band, the ERD was comparable between O and OI activities across the precentral, central and parietal electrodes. OM involved the same regions but had greater ERD over the central electrodes. In the beta band, there was a gradation of ERD intensity in O, OI and OM over central electrodes. After the task, the ERS changes were weak during the O task but were strong during the OI and OM (Cz) tasks, with no differences between OI and OM. CONCLUSION: Alpha band ERD results demonstrated the recruitment of mirror neurons during lower limb VOT due to visual feedback. Beta band ERD reflects strong recruitment of the sensorimotor cortex evoked by motor imagery and action execution. These results also emphasize the need for an active motor task, either motor imagery or motor execution task during VOT, to elicit a post-task ERS, which is absent during passive observation.

RESUMEN

This study compared the effects of video feedback (VF) as a stand-alone intervention and video modeling plus video feedback (VMVF) for improving soccer players' static ball control skills. Research has suggested that VF alone and VMVF produce substantial improvements for young athlete's skills, though no studies have compared the two. Therefore, we used a multiple-baseline-across-participants design with embedded alternating treatments to compare VF and VMVF. Two 10-year-old female soccer players and one 9-year-old male soccer player participated. The first author implemented the VF and VMVF training procedures and assessed the same three target behaviors across participants. The results suggested that VF and VMVF produced similar increases in performance for two of three participants and that VMVF produced slightly greater increases for one participant. In addition, both interventions were effective at substantially improving ball control skills from baseline levels and relative to a control skill.

RESUMEN

AIMS: To investigate effect of a video feedback approach in clinical teaching of gastroenterology for nursing students. METHODS: In this study, we selected 100 eligible student interns who meet the enrollment criteria from The First Affiliated Hospital of Ningbo University from March 2021 to March 2023. According to their personal choices, 50 interns were assigned to a control group (traditional teaching methods), while the other 50 interns were assigned to an observation group (video feedback methods). We compared theoretical knowledge, practical skills, and comprehensive ward-round abilities between the two groups, as well as doing an evaluation of teaching behaviors of the supervising teachers at the end of the clinical internship. RESULTS: The observation group significantly outperformed the control group in theoretical and practical assessments (P<0.05). The observation group also scored higher in nursing inquiry, examination, diagnosis, interventions, health consultation, humanistic care, organizational effectiveness, and overall evaluation (P<0.05). In addition, the total score of critical thinking (267.24±16.87 points) and scores of the individual dimensions in the observation group were higher than those of the control group (257.64±13.84 points), (P<0.001). CONCLUSION: The video feedback method can effectively improve the theoretical knowledge, practical skills, and overall ward-round performance of students in clinical nursing interns in the field of gastroenterology. Additionally, this approach can standardize teaching behaviors and enhance student satisfaction.

RESUMEN

BACKGROUND: Patients who attend emergency surgical services are entering an unfamiliar environment whilst often being unwell and in pain. Patient satisfaction in emergency surgical units is often low due to poor communication with attendees and long wait times. METHODS: A pilot patient questionnaire identified areas where patient satisfaction was low during attendance at the surgical assessment unit (SAU). The aim of this intervention was to improve patient satisfaction with their experience whilst attending the SAU. An education video was filmed to address the areas where services were falling short of expectations, and this was played in the waiting room. Further questionnaire results tailored the frequency of the video to achieve maximum impact. RESULTS: Data were collected at three time points: firstly, prior to the introduction of the video (n=34); secondly, with the video played hourly (n=15); and finally with the video played every 30 minutes at a higher volume (n=15). Mean satisfaction scores after the final cycle improved to 7.3 from 4.9 (p=0.0009). Additionally, 94% of patients agreed that the video was in keeping with their personal experience of the SAU and agreed that the video improved their understanding of what to expect from the visit. CONCLUSIONS: Interventions that improve communication with patients and adjust their expectations play an important role in improving patient satisfaction and their overall perception of care. This can be achieved with a simple patient information video.

RESUMEN

Postpartum depression (PPD) symptoms can negatively influence mother-infant interactions. Video-Feedback Interaction Guidance for Improving Interactions Between Depressed Mothers and their Infants (VID-KIDS) is a parenting intervention that allows mothers experiencing PPD symptoms to observe and improve their interactions with their infants. VID-KIDS has also positively influenced infants' stress (cortisol) patterns. There is limited research on maternal perspectives of interventions like VID-KIDS. In this hermeneutic study, four mothers were interviewed to increase understanding of the VID-KIDS experience. Key findings included: 1) VID-KIDS provided an opportunity for mothers with PPD symptoms to positively transform their identity; 2) VID-KIDS provided a chance to witness the mother-infant relationship forming and improve maternal mental health t, and; 3) VID-KIDS provided a space for mothers to dialogue about their experience with PPD symptoms authentically. VID-KIDS promoted healing from PPD as mothers experienced a transformation in how they perceived themselves and their relationships with their infants.

RESUMEN

AIMS/BACKGROUND: We aimed to adapt, pilot and explore experiences of receiving and delivering the video feedback intervention for positive parenting (VIPP) for 2 to 6 month old babies, mothers experiencing moderate to severe perinatal mental health difficulties and perinatal mental health clinicians. DESIGN/METHODS: The VIPP intervention was adapted to include developmentally appropriate activities and developmental psychoeducation for 2 to 6 month olds, alongside psychoeducation on emotion regulation, and then piloted in 14 mothers experiencing moderate to severe perinatal mental health difficulties (registration ISRCTN64237883). Observational and self-reported pre-post outcome data on parenting and parent-infant mental health was collected, and post-intervention qualitative interviews were conducted with participating mothers and clinicians. RESULTS: Consent (67%), intervention completion (79%) and follow-up rates (93%) were high. Effect sizes on pre-post outcome measures indicated large improvements in parenting confidence and perceptions of the parent-infant relationship, and a medium-size improvement in maternal sensitivity. In qualitative interviews, clinicians and mothers described how mothers' initial anxieties about being filmed were allayed through receiving positive and strengths-focussed feedback, boosting their self-confidence, and that the video feedback facilitated identification of young babies' subtle behavioural cues and moments of mother-infant connection. Streamlining the information provided on maternal emotion regulation, and allowing increased use of clinical judgement to tailor intervention delivery, were suggested to optimise intervention feasibility and acceptability. CONCLUSION: It is feasible and acceptable to implement VIPP with very young babies and their mothers experiencing perinatal mental health difficulties. A fully powered randomised controlled trial is required to establish intervention efficacy.

RESUMEN

BACKGROUND: To evaluate the effectiveness of instillation technique education using self-video feedback in glaucoma patients. METHODS: Sixty-two patients who self-instilled glaucoma eyedrops were randomly assigned to the self-video feedback and control groups according to the block randomization. Each group of the patient was asked to instill eyedrops, and videos were recorded. For the control group, only an educational video was provided. In the self-video feedback group, the patients provided educational video and feedback using a recorded video of their own instillation. After 1 month of education, the patient's instillation techniques were video-recorded again. We divided the steps of instilling eyedrops into ten steps and evaluated whether each step was properly performed using the recorded images from each patient. The main outcome was the proportion of patients who properly instilled their eyedrops in each step. RESULTS: Before education, there was no significant difference in the proportion of patients who were properly instilled between the two groups. In the group that received video feedback, the proportion of patients who instilled the eyedrops correctly after education in some items was significantly higher than that of the control group, and in particular, the educational effect of 'avoids touching dropper to eyelid or eyelash' was superior. CONCLUSIONS: In patients with glaucoma, education on the method of instillation was effective in improving the techniques of instillation. In the items that required accurate actions, the video feedback that allowed the patient to observe themselves had a better improvement effect compared to the traditional education method.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate the effectiveness of implementation of video feedback combined with peer role-playing (PRP) teaching method in medical undergraduates adopting problem-based learning (PBL) teaching mode. METHODS: The undergraduates of five-year clinical medicine who get enrollment of Wuhan local University from 2016 and 2018 were selected to be the research objects. The same grade level is randomly divided into several groups to carry out PBL, with 6-10 students in each group. Following the principle of voluntary participation, 34 students were enrolled in the study group and 33 students in the control group finally. The research regards group as the unit, and study report in group should be carried out to fulfill the research. In the study group, the students were asked to perform PRP report, and the report videos were used for feedback. At the same time, the control group reported by PPT, and the feedback was carried out according to the PPT. At the end of the study, the "Competency Improvement Satisfaction Questionnaire (CISQ)" was distributed to investigate students' satisfaction with this teaching method to improve their ability, Arizona Clinical Interview Score (ACIR) was administered in Chinese by a trained teacher unrelated using PRP method to assess students' clinical inquiry ability and communication skills, and theory test was performed to assess mastery of theoretical knowledge. RESULTS: The results show that the study group is superior to the control group in improving the interest of learning and the ability of independent learning, interpersonal communication and active problem solving. Although it is in terms of the confidence in becoming a real doctor and the ability of teamwork, language expression, clinical thinking cultivated, active knowledge acquired and understood that study group are better than the control group, the difference was not statistically significant. ACIR shows that the study group is significantly better than the control group in organization, timeline planning, and transition statements, openly questioning, smooth progress, and avoiding repetition, summarizing, understandable language, documentation and total score. There is no significant difference in eye contact and no interruption. The differences between the two groups are not statistically significant in terms of responsing to concerns, positive feedback, and additional questions. The theoretical test scores of the study group are significantly higher than those of the control group. CONCLUSION: Video feedback combined with peer role-playing teaching method implemented in medical undergraduates adopting PBL teaching mode is effective, it could stimulate interest in learning actively, improve interpersonal communication ability, improve learning efficiency and clinical knowledge and skills, and improve the confidence of becoming a real doctor. It is worthy of further research and promotion.

RESUMEN

Purpose: This study aimed to examine the effect of self-controlled video feedback on the learning of tactical motor skills in tennis, and additionally, whether this was affected by learners' self-efficacy and self-regulative skills. Method: Twenty-three intermediately skilled tennis players were assigned to either a self-controlled group that was provided video feedback on request or a yoked group that received an identical, externally controlled video feedback schedule. In three training sessions participants practiced serve and volley play. Video feedback with attentional cueing and transitional statements that focused solely on individual tactical gameplay was provided by a licensed tennis coach. Individual tactical performance was measured with a custom designed Tactical Tennis Tool (TTT) in a pretest, posttest and in a one-week retention test. Before each test self-efficacy was measured, and a questionnaire was administered to measure self-regulative skills. Results: Analyses revealed significantly larger improvements in tactical performance relative to the pretest for the self-controlled group than for the yoked group in both the posttest and the one-week retention test. No differences were found in self-efficacy. Finally, the improvements in tactical performance were not predicted by self-efficacy and/or self-regulative skills. Conclusion: The advantage of self-controlled video feedback extends to the learning of a complex tactical task in tennis. Future research should verify the observed benefits of a self-controlled learning environment in comparison to a coach-controlled learning environment.

RESUMEN

Parent-implemented Naturalistic Developmental Behavioral Interventions (NDBIs), rooted from applied behavioral and developmental sciences, focus on empowering families by training and coaching natural change agents to embed evidence-based strategies during regular events or contexts (e.g., play time). No research, however, has relied on strength-based video feedback coaching within parent-implemented NDBIs while providing flexibility with self-recorded sessions. We conducted a single case multiple-baseline design across five parent-child dyads to evaluate the effects of a telepractice-based parent-training on five NDBI strategies (i.e., Follow and Imitate, Model Language, Arrange Environment, Wait Time, Reward and Expand), utilizing strength-based video feedback coaching with parents (i.e., two mothers and three fathers) of young autistic children (i.e., ages 2 to 5) on parent strategy use and child social communication. An additional coaching package (i.e., parent self-reflections, goal setting, and joint discussions) was introduced to parents who did not meet a predetermined criterion. Maintenance data were collected 2-, 4-, and 6-weeks after intervention concluded. Visual analyses, nonoverlap calculations, and standardized mean difference effect sizes indicate strong effects for parent strategy use and small, varied effects on child social communication. Maintenance of parent strategy use and child social communication varied, with most remaining at equivalent or higher levels. Parent-implemented interventions that are delivered via telepractice may continue to be successful when coaching is focused on the parents' strengths, all coaching feedback is provided asynchronously, and families can flexibly record sessions based upon their week's schedules rather than relying on regularly scheduled meeting times with a coach.

RESUMEN

Introduction: Mothers' representations of their infants are important intervention targets because they predict the observed quality of infant-mother interactions. The current study investigated the influence of a video-feedback infant-parent intervention on mothers' representations of their infants beyond the effect of standard treatment. Methods: Data from a naturalistic, randomized controlled trial of 152 predominantly low- to moderate-risk mothers (mean age = 29.7 years) with infants (mean age = 7.3 months) were used. At Well Baby Centers, all families followed the universal program, which was treatment as usual (TAU), whereas half of the families also received the intervention. The Working Model of the Child Interview categories and scales as well as three latent factors generated from a factor analysis were used to assess maternal representations at baseline and follow-up (9-13 months after baseline). A linear mixed model analysis was used to analyze the data. Results: There were no differences in representation changes from baseline to follow-up between the control group (TAU) and intervention group. When both groups were combined, there were minor improvements in the mothers' representations at the follow-up. Discussion: Aspects of the intervention, the quality of TAU, and the homogeneity scores of the predominantly low-risk sample may explain the intervention's lack of effect on mothers' representations beyond TAU. The supportive services at Norwegian Well Baby Centers as well as the infants' increasing age putatively contributed to the improved features of the mothers' representations in the total sample. That standard community care may affect maternal representations has not been shown before. Future research should identify the core components in interventions targeting maternal representations and examine whether those components can be incorporated in primary care. Including measures of mothers' reflective functioning could broaden our knowledge of representations and their changeability. Clinical trial registration: This study is registered in the International Standard Randomized Controlled Trial Number registry under the reference number ISRCTN 99793905.

RESUMEN

OBJECTIVE: This study aimed to compare two methods of feedback: verbal face-to-face feedback after direct observation (F2F-feedback) versus electronic-written feedback after observation of recorded-VDO of student's performance (VDO-feedback), in terms of effectiveness in improving skill, effects on motivation and satisfaction. BACKGROUND: Medical schools are responsible for teaching and ensuring proficiency of basic surgical skills. Feedback is effective in developing psychomotor skills; by providing information of learner's current performance, how to improve, and enhancing motivation. MATERIALS AND METHOD: Fifty-eight medical students (3rd- 4th year) were trained to perform vertical mattress suture in small groups. Then, during 6-week period of self-directed practice, students were randomized into group1 VDO-feedback (male:female = 21:8) and group 2 F2F-feedback (male:female = 20:9). Feedbacks were provided once every 2 weeks (Week2, Week4). End-of-rotation OSCE was at Week6, and retention tested was at Week8. Performance checklist (Cronbach's Alpha 0.72) was used to assess skill at 4 timepoints; pre- and post- small group learning, OSCE, and retention phase. Questionnaire was used to assess motivation, learning strategies and satisfaction (Cronbach's Alpha 0.83). RESULT: After in-class learning, further significant improvement of skills could be gained by both F2F- and VDO- feedbacks (p < 0.0001). Both could similarly retain skill for at least 4 weeks later without additional practice. Self-efficacy, test anxiety, and cognitive strategies scores were significantly increased in both groups (p < 0.05). Extrinsic motivation was increased in VDO-feedback group. No difference in satisfaction between groups was observed. DISCUSSION AND CONCLUSION: VDO-feedback could be alternative to F2F-feedbacks for basic surgical skill training when limitation for simultaneous meeting of teacher and students occurs. TRIAL REGISTRATION: This study has been registered to Thai Clinical Trial Registry (WHO International Clinical Trial Registry Platform) on 11/07/2023 (TCTR20230711005).

RESUMEN

Previous behavior-analytic research to improve dance performance has separately demonstrated the efficacy of TAGteach and self-evaluative video feedback. However, no research has directly compared these two interventions. In this study, we used an adapted alternating-treatment design to examine the effects of TAGteach versus self-evaluative video feedback to improve the accuracy of dance movements among four beginner-level dance students. All participants performed better on movements that were taught using TAGteach compared with those that were taught using video self-evaluation. However, conclusions about the superiority of TAGteach should be tempered until further research on this topic is conducted.

RESUMEN

The present study examined the effectiveness of a personalized remote video feedback parenting program to improve mother-child interactions and child behavior outcomes among mothers of children with behavior problems in comparison to counterparts with no behavior problems. The sample comprised 60 mothers and their 2-to-6-year-old children, including children with behavior problems (BP = 19) and children without behavior problems (NoBP = 41). The Strengthening Bonds program included one in-person group session and remote personalized video feedback about their mother-child interactions in a play situation via smartphone for six weeks. Mother-child interactions were the primary outcome, and children's behaviors were the secondary outcome. Pre- and post-intervention assessments were performed. The mother-child interactions were recorded during free- and structured-play situations and were then analyzed by the Parenting Interactions with Children: Checklist of Observations Linked to Outcomes (PICCOLO) and the Dynamics of the dyad activity coding system. Additionally, the mothers answered the Strengths and Difficulties Questionnaire. The results showed that, in the post-intervention, the mother-child interaction pattern improved in the BP group, especially in the teaching dimension of the PICCOLO. Also, after the program, more children with normal classification were in the BP group.

RESUMEN

Providing choices, i.e., autonomy, to athletes during practice increases intrinsic motivation and positively influences the motor learning process. The effects of autonomy on the timing of feedback (self-controlled timing of feedback) when optimizing the movement execution of sidestep cutting (SSC), a task that is highly related with ACL injury risk, are unknown. The aim of this study was to investigate the effect of self-controlled timing of video and EF-feedback on movement execution of SSC in team sport athletes. Thirty healthy ball team sport athletes (22.9 ± 1.7 years, 185.5 ± 7.2 cm, 79.3 ± 9.2 kg) were recruited from local sports clubs. Participants were alternately assigned to the self-control (SC) or the yoked (YK) group based on arrival and performed five anticipated and five unanticipated 45° SSC trials as pre-, immediate-post and one-week retention test. Movement execution was measured with the Cutting Movement Assessment Score (CMAS). Training consisted of three randomized 45° SSC conditions: one anticipated and two unanticipated conditions. All participants received expert video instructions and were instructed to 'try to do your best in copying the movement of the expert'. The SC group was allowed to request feedback whenever they wanted during training. The feedback consisted of 1) CMAS score, 2) posterior and sagittal videos of the last trial and 3) an external focus verbal cue on how to improve their execution. The participants were told to lower their score and they knew the lower the score, the better. The YK group received feedback after the same trial on which their matched participant in the SC group had requested feedback. Data of twenty-two participants (50% in SC group) was analyzed. Pre-test and training CMAS scores between groups were equal (p > 0.05). In the anticipated condition, the SC group (1.7 ± 0.9) had better CMAS scores than the YK group (2.4 ± 1.1) at the retention test (p < 0.001). Additionally, in the anticipated condition, the SC group showed improved movement execution during immediate-post (2.0 ± 1.1) compared to pre-test (3.0 ± 1.0), which was maintained during retention (p < 0.001). The YK group also improved in the anticipated condition during immediate-post (1.8 ± 1.1) compared to pre-test (2.6 ± 1.0) (p < 0.001) but showed decreased movement execution during retention compared to immediate-post test (p = 0.001). In conclusion, self-controlled timing of feedback resulted in better learning and greater improvements in movement execution compared to the control group in the anticipated condition. Self-controlled timing of feedback seems beneficial in optimizing movement execution in SSC and is advised to be implemented in ACL injury prevention programs.

RESUMEN

BACKGROUND: Numerous observational studies show associations between family meal frequency and markers of child cardiovascular health including healthful diet quality and lower weight status. Some studies also show the "quality" of family meals, including dietary quality of the food served and the interpersonal atmosphere during meals, is associated with markers of child cardiovascular health. Additionally, prior intervention research indicates that immediate feedback on health behaviors (e.g., ecological momentary intervention (EMI), video feedback) increases the likelihood of behavior change. However, limited studies have tested the combination of these components in a rigorous clinical trial. The main aim of this paper is to describe the Family Matters study design, data collection protocols, measures, intervention components, process evaluation, and analysis plan. METHODS/DESIGN: The Family Matters intervention utilizes state-of-the-art intervention methods including EMI, video feedback, and home visiting by Community Health Workers (CHWs) to examine whether increasing the quantity (i.e., frequency) and quality of family meals (i.e., diet quality, interpersonal atmosphere) improves child cardiovascular health. Family Matters is an individual randomized controlled trial that tests combinations of the above factors across three study Arms: (1) EMI; (2) EMI + Virtual Home Visiting with CHW + Video Feedback; and (3) EMI + Hybrid Home Visiting with CHW + Video Feedback. The intervention will be carried out across 6 months with children ages 5-10 (n = 525) with increased risk for cardiovascular disease (i.e., BMI ≥ 75%ile) from low income and racially/ethnically diverse households and their families. Data collection will occur at baseline, post-intervention, and 6 months post-intervention. Primary outcomes include child weight, diet quality, and neck circumference. DISCUSSION: This study will be the first to our knowledge to use multiple innovative methods simultaneously including ecological momentary intervention, video feedback, and home visiting with CHWs within the novel intervention context of family meals to evaluate which combination of intervention components are most effective in improving child cardiovascular health. The Family Matters intervention has high potential public health impact as it aims to change clinical practice by creating a new model of care for child cardiovascular health in primary care. TRIAL REGISTRATION: This trial is registered in clinicaltrials.gov (Trial ID: NCT02669797). Date recorded 5/02/22.

RESUMEN

BACKGROUND: Video feedback is a technique used in cognitive therapy for social anxiety disorder (CT-SAD) to update patients' negative self-perceptions of how they appear to others. Clients are supported to watch video of themselves engaging in social interactions. While typically undertaken in session with a therapist, this study aimed to investigate the effectiveness of remotely delivered video feedback embedded within an Internet-based cognitive therapy program (iCT-SAD). METHODS: We examined patients' self-perceptions and social anxiety symptoms before and after video feedback in two randomised controlled trials. Study 1 compared 49 iCT-SAD participants with 47 from face-to-face CT-SAD. Study 2 was a replication using data from 38 iCT-SAD participants from Hong Kong. RESULTS: In Study 1, ratings of self-perceptions and social anxiety showed significant reductions following video feedback, in both treatment formats. 92 % of participants in iCT-SAD, and 96 % in CT-SAD thought they looked less anxious compared to their predictions after viewing the videos. The change in self-perception ratings was larger in CT-SAD compared to iCT-SAD, but there was no evidence that the impact of video feedback on social anxiety symptoms around a week later differed between the two treatments. Study 2 replicated the iCT-SAD findings of Study 1. LIMITATIONS: The level of therapist support in iCT-SAD videofeedback varied with clinical need and was not measured. CONCLUSIONS: The findings indicate that video feedback can be delivered effectively online, and that its impact on social anxiety is not significantly different from in-person treatment delivery.
