| Technical issues |
| Lack of equipment | - A kit is mailed to caregivers which includes a microphone and a webcam that is already mounted on a tripod ready-to-use by families. - If a family does not have access to a laptop, we provide a laptop with pre-loaded videoconferencing software. |
| Setup and troubleshooting of hardware and software | - A step-by-step installation guide for hardware equipment (webcam, tripod, and microphone) and video-conferencing software setup including written instructions, snapshots, and instructional videos are provided via email. - Caregivers are guided through the actual hardware and software setup process during the tech-support session conducted via a phone call. - Following successful setup of the hardware and software, the family is sent an email with a password-protected Zoom link for a live session. - All audio and video settings are tested and optimally configured during this live session in preparation of the next virtual session with the child. |
| Connectivity issues | - If the family is facing streaming issues during the test video-call using video-conferencing software, we try to identify the area of their house where they may have the best internet access and test the quality of the connection from that location. - If needed, caregivers may be asked to limit the number of devices using the internet at the time of the scheduled call with the research team to ensure better streaming speeds and audio/video quality during the call. |
| Type of view on videoconferencing software | - Caregivers are provided information on different view types (e.g., gallery and speaker views) during the test video-call and the research team recommends the ideal view to be used during the intervention sessions. - Specifically, caregivers are asked to try out different viewing options during the virtual tech-support session so that they are familiar and comfortable changing these settings. - Caregivers are recommended to use the gallery/grid view during group training sessions (so that child can see all participants in the session) and speaker/focus view during fine motor activities using small objects. |
| Participant issues |
| Setup of environment | - The caregiver in collaboration with the research team identify a quiet, distraction-free area during the tech-support session that can be reserved for training sessions. - Caregivers are requested to adjust furniture and remove any items that block views to ensure that both the child and caregivers are visible throughout the training sessions. - As mentioned above, caregivers are guided to figure out optimal camera position and room lighting in the reserved space for testing/training. |
| Child/or caregiver not in view | - Adjustments to camera position are made by the caregiver in an ongoing manner during the session to ensure that the child is always in full view of the camera. |
| Child/caregiver not heard | - Caregivers are reminded to turn on the microphone at the start of every session and we request them to place it as close to the child as possible to ensure optimal sound quality. - If it is hard to hear the child's responses, we always ask the caregivers for clarification on what the child is trying to communicate. Caregivers are also encouraged to intimate the clinician/confederate if they observe any non-verbal communicative behaviors (pointing, signs for “more,” “all done,” etc.) that the clinician/confederate may have missed. |
| Clinician not seen/heard | - To ensure that the clinician/confederate are appropriately visible and heard, they also use a tripod mounted webcam and a microphone at their end. |
| Intervention-related issues |
| Clinician-played music not heard | - To allow music played on the clinician's laptop to be transmitted through video-conferencing software and be audible to the child/caregiver, we enable settings in the video-conferencing software that allow the clinician to “share sound.” - The clinician uses a speaker to ensure adequate amplification of played sound so that it can be heard loud enough at the child's end. - In addition, the music files are also sent to caregivers ahead of time of the session. In case caregivers are having trouble hearing the music, they are asked to play these music files at their end during the sessions. |
| Unclear expectations regarding sessions | - We use picture boards to clearly indicate the activities for the day and transitions between activities to the children. - We make a behavioral agreement with the child at the start of each session using a rules sheet that uses words and pictures to list do's and don'ts for the session. The child is provided an intermittent reminder of the rules as needed during the rest of the training session to ensure the child's compliance. |
| Clinician movements/training activities not clear | - The clinician and the adult confederate ensure that their movements are large and exaggerated in amplitude to be clearly visible to the child and their caregiver. - The clinician, confederate, and the child/caregiver have identical kits of training supplies. This allows children to better follow the instructional bids of the clinician/confederate using supplies/props. - Instructions are provided in a multimodal format, i.e., we show children pictures of movements to be practiced, the virtual and in-person partners provide a visual demonstration of movements, we use short verbal descriptors of movements such as “tap and clap,” “hands up and down” to cue key movement components during our demonstration and during the child's practice, and the caregiver may also provide manual assistance or physical prompting as required by the child during movements/activities. |
| Child running away during sessions | - We set clear expectations with the child about session structure at the outset of the session by using a visual schedule and by going through a rules sheet for the session. - During sessions, the child is encouraged by the clinician to clearly communicate gesturally/verbally/using pictures if they need a break. - We solicit parental input on strategies to engage the child, for e.g., call-response ideas such as “macaroni & cheese… everybody freeze” (to get the child to stay on their spot), or use of phrases such as “eyes on John” (to get the child to focus on their virtual partner), or showing pictures of cartoon characters doing exercises (to motivate the child to exercise with their favorite character), etc. - The session is structured to include short 3–5 min activity bursts followed by opportunities for scheduled 30 sec to 1 min breaks if required by the child. - We work with the family to identify the child's familiar/preferred reinforcement system and adopt it during our sessions, for example, token economy, stickers, quick iPAD break, etc. |
| Child inattention toward laptop screen | - Caregiver is asked to provide a visual model of ideal interactions with virtual partners. - The clinician and confederate use loud voices and clear, brief instructions to solicit and sustain child's attention. - During whole-body activities, there are built-in times between activities when caregivers and the child are asked to sit down in front of screen to observe the movement demo provided by the clinician/confederate, or to engage in conversations/social exchanges, or to see pictures of activities that will be practiced next, or power point slides of their favorite cartoon characters encouraging them to practice training activities. - The clinician/confederate regularly (typically after every activity) initiate gestural reinforcement bids such as virtual high-fives, fist bumps, etc. where children are typically asked to come to the screen and give high-fives to their virtual partners. - We also use call-response strategies to solicit child's attention: e.g., “Hocus-focus… time to focus,” etc. - We use playful games with clear functional goals (improve accuracy, timing, speed, etc. of movement performance) to challenge the child. |
| Inadequate practice of training activities | - Caregivers are provided a list of online resources (short YouTube videos) and parent training activities every week that are tailored to their child's interests to facilitate practice of similar activities beyond the training sessions. - Caregivers are also sent email or text reminders to practice activities with their child each week. These activities are also documented in a weekly training diary that is filled out by researchers in collaboration with caregivers at the end of the training sessions. |
