Evaluation of a Video Prompting and Fading Procedure for Teaching Dish Washing Skills to Adults with Developmental Disabilities

We evaluated a video prompting and fading procedure for teaching three adults with developmental disabilities to wash dishes. Video prompting involved showing video clips depicting each step of the task. All three adults reached 90–100% correct when video prompting was implemented. Following acquisition, video prompting was withdrawn, but performance deteriorated. Subsequently, a 3-step fading procedure was implemented in which the separate video clips were merged to form larger, multi-step segments of video. Performance reached 80–100% correct as the video prompts were re-applied and then faded. Performance decreased at the 3-month follow-up when prompting was removed, but stabilized at 80–90% correct when the third step in the fading sequence was reinstated. These data suggest a promising approach for fading video prompts.     

Young adults with intellectual and other developmental disabilities acquire vocational skills with video prompting

Students with intellectual and other developmental disabilities often require substantial support to acquire the skills needed to secure work experience and paid employment. Prior findings suggest that video prompting is likely to be an effective and feasible strategy for establishing such skills. To evaluate this possibility in a special education transition program, we examined the effectiveness of a video prompting procedure in teaching 8 young adults with developmental disabilities to perform job-related tasks (doing laundry, checking in to work, vacuuming, stripping bed). The intervention was effective with all participants. The skills maintained over 3 months, and the participants performed the tasks accurately in a new setting with different materials. Participants were reportedly satisfied with the intervention and deemed it easy to use.     

Teaching a simple meal preparation skill to adults with moderate and severe mental retardation using video modeling

We evaluated whether adults with mental retardation in the moderate or severe range would acquire simple meal preparation skills via video modeling. Training was conducted in the kitchen of the participants' day treatment setting. The intervention consisted of (i) watching a video of an adult with a developmental disability making a peanut butter and jelly sandwich and (ii) receiving verbal praise for each step of the task that was performed correctly. All three participants mastered the task and demonstrated generalization across settings. All three participants also demonstrated maintenance of the skill one month following mastery.

Improving accepting and giving compliments with individuals with developmental disabilities

Individuals with developmental disabilities, such as autism spectrum disorder, typically exhibit conversation skill deficits, with two prevailing deficits including giving and accepting compliments. The current study used an individualized approach to assess and teach accepting and giving compliments specific to performance, possession, and appearance with three adolescents and young adults with developmental disabilities. We taught these skills using behavioral skills training and prompting during conversations utilizing a multiple-baseline design across participants. We also observed generalization and treatment extension of the participants' skills in conversations with adults not associated with teaching and in the absence of any teaching procedures. The results support the efficacy of the procedures used toward improving giving and accepting compliments within the context of a conversation. We discuss considerations to improve the social acceptability of and refinements to the teaching procedures and acquired skills.     

Task analysis,correspondence training,and general case instruction for teaching personal hygiene skills

The effect of a 10‐step task analysis, general case instruction, and correspondence training was evaluated for teaching appropriate personal hygiene following bowel movements. Correspondence training maintained a central role in this study. According to Israel (1978), the relationship between an individual's verbal and nonverbal behaviors is influential in self‐instruction training. Essentially, correspondence training encourages an individual to generate his or her own instructional cues; in consequence, the procedure can be instrumental in ensuring the maintenance and generalization of important verbal and nonverbal behavior. Three adults with developmental disabilities participated in this study. The dependent variables included the level of assistance required on each step of the task analysis and an end of sequence rating on a three‐point Likert‐type cleanliness scale. Results showed that all three participants learned to care for themselves appropriately following bowel movements. Moreover, the skills generalized to other settings and were maintained over a nine‐month period. The target skill was evaluated against the five criteria for a behavioral cusp and met the criteria for ‘an important behavior change’ (Bosch & Fuqua, 2001, p. 123).

Using video modeling to teach a domestic skill with an embedded social skill to adults with severe mental retardation

We assessed whether three adults with severe mental retardation would acquire a domestic skill (making coffee) with an embedded social skill (serving coffee to and sitting down beside a peer) via video modeling procedures. Training was conducted in a classroom in the participants' day treatment setting. The intervention consisted of (i) watching a video of an adult with a developmental disability making coffee and initiating a social interaction with a peer; and (ii) receiving verbal praise for each step of the task that was performed correctly. All three participants mastered the task and demonstrated generalization across settings, stimuli, and people. Two participants performed with 100% accuracy on maintenance probes conducted 1 month following mastery, and one participant did so following booster training.

The Effectiveness of Using a Video iPod as a Prompting Device in Employment Settings

The purpose of this study was to evaluate the effectiveness of using a video iPod as a prompting device for teaching three job-related tasks to a young man with developmental disabilities in a community-based employment setting. The effectiveness of the prompting device was evaluated using a multiple probe across behaviors design. Results indicated that the introduction of the video iPod was associated with immediate and substantial gains in independent correct responding with an associated decrease in the number of prompts given from a job coach. In addition, the participant used the video iPod independently. Instructional implications and future research will be discussed.     

Three Students with Developmental Disabilities Learn to Operate an iPod to Access Age-Appropriate Entertainment Videos

Students with developmental disabilities may not have the necessary skills or the same opportunities to access multimedia-based leisure materials as their typical peers. Portable multimedia devices such as the iPod Touch® may provide them with a useful tool for accessing age-appropriate leisure material. The present study examined the feasibility of teaching 3 students with developmental disabilities to independently operate an iPod to watch age-appropriate entertainment videos. A delayed multiple-probe design across participants was implemented with baseline, intervention, fading, and follow-up phases. Video modeling and least-to-most response prompting were successfully used to teach these 3 students to operate an iPod Touch® to watch preferred videos without adult assistance. The results complement previous findings supporting the use of video modeling as an instructional strategy and add to the literature by using portable multimedia devices as assistive technology for teaching an age-appropriate leisure skill.     

Using Self-Directed Video Prompting to Teach Students with Intellectual Disabilities

This study examined the effects of self-directed video prompting presented via an iPod Touch on teaching four adolescents with moderate-to-severe intellectual and developmental disabilities two daily living tasks. Students were taught to wash a table using instructor-delivered video prompts. After reaching 80 % correct for at least three consecutive sessions, a system of most-to-least prompts was used to teach them to use the iPod Touch and a video prompting app (inPromptu) independently. In the final phase, students used inPromptu on the iPod Touch to teach themselves to vacuum with self-directed video prompts. Results of the study demonstrate that all four students learned to wash a table with instructor-directed video prompts, they all learned to use inPromptu on the iPod Touch independently, two students used inPromptu on the iPod Touch to teach themselves to vacuum, and a third student was learning to vacuum using inPromptu.     

Comparison of prompting procedures to teach internet skills to older adults

The Internet and information and communications technologies (ICTs) have been found to produce meaningful social interactions and greater social support among older adults (White et al., 2002 ). Despite these benefits, the Internet and ICTs are not widely used among the older‐adult population (Cresci, Yarandi, & Morrell, 2010 ). The purpose of the current study was to compare the effectiveness and efficiency of video prompting and text‐based instructions on the acquisition of three tablet‐based tasks: emailing, video calling (FaceTime® application), and searching for a YouTube? video. Both video prompting and text‐based instructions were effective for all three participants, with text‐based instructions being slightly more efficient for one participant and video prompting being more efficient for two participants, suggesting that both prompting procedures can be used to teach older adults Internet and ICT skills.     

Using telehealth to teach valued skills to adults with intellectual and developmental disabilities

Telehealth uses electronic information and telecommunication technologies to deliver long-distance clinical services. It has successfully been used by clinical professionals to teach family and staff members to provide evidence-based assessment and treatment procedures. There is no research to date, however, evaluating the use of telehealth to directly teach individuals with intellectual and developmental disabilities (IDD). Thus, we evaluated the efficacy of a telehealth intervention using total task chaining with least-to-most prompting delivered via videoconference to 2 adults with IDD. Both participants demonstrated low independent responding during baseline with enhanced written instructions present. During intervention, which included vocal and model prompting, both participants met the mastery criterion for each skill in fewer than 15 sessions, which maintained after 2 weeks. Finally, both participants expressed satisfaction with the goals, procedures, and effects of the intervention. We discuss the broader scope of the intervention for individuals with disabilities when face-to-face services may not be feasible.     

A comparison of prompting methods to teach sight words to students with autism spectrum disorder

Time delay procedures are one of the most commonly used and effective strategies for teaching sight words to learners with disabilities. However, less is known about whether they are differentially effective and efficient with learners. This study compared the effectiveness and efficiency of progressive time delay and simultaneous prompting on sight word acquisition among three learners with autism spectrum disorder using an adapted alternating treatments design across word sets. For two participants, both procedures led to skill acquisition with no clear differences in efficiency. For the remaining participant, neither procedure was effective; therefore, the reading task was changed to a receptive one, and a stimulus fading intervention package was implemented.     

Teaching Pedestrian Skills to Individuals with Developmental Disabilities

The purpose of the present study was to examine the effectiveness of most to least prompting on teaching pedestrian skills to individuals with developmental disabilities. Five individuals with developmental disabilities were taught three different pedestrian skills, all related to crossing the streets, using simulation activities on a road model in the gym of their school. A multiple probe design across behaviors was used to evaluate the effects of most to least prompting. The results of the study revealed that most to least prompting was effective in teaching pedestrian skills. The subjects learned each of the skills and managed to generalize these skills to the actual city traffic.     

Token‐economy‐based contingency management increases daily steps in adults with developmental disabilities

Adults with developmental disabilities are less likely to meet physical activity guidelines than typically developing counterparts. Contingency management (CM) interventions increase physical activity in sedentary adults. The current study systematically replicated previous research among sedentary adults diagnosed with developmental disabilities living in a residential group home, using a token economy in the context of a CM intervention. Using a changing criterion design, participants (N = 4) were given tokens contingent on meeting increasing step goals over 8 weeks, tracked via a Fitbit Flex?. CM increased the number of steps substantially for three of four participants. These findings extend previous research supporting the use of token‐based CM interventions for increasing daily steps among individuals with developmental disabilities. Because the current study was conducted in a residential group home setting, it may offer a long‐term sustainable approach to improving the health of some individuals living with developmental disabilities.     

A Picture-Based Activity Schedule Intervention to Teach Adults with Mild Intellectual Disability to Use an iPad During a Leisure Activity

Individuals with developmental disabilities have limited opportunities to participate in leisure activities, frequently due to lack of skills. The purpose of the current study was to teach three adults diagnosed with mild intellectual disability to use an iPad in the context of playing the video game Angry Birds. We used an adapted multiple baseline across participants research design to teach the task, which included opening the cover of the iPad, unlocking the device, opening Angry Birds, playing the game, and putting the iPad away. Instruction took place during breaks in a private room at a sheltered workshop. During intervention, participants had access to an activity schedule to aid in completion of the task. In some cases, extra prompts were provided to increase attention to the activity schedule. All three participants showed improvement in the target skill with intervention and gains were sustained during the maintenance phase.     

Teaching children with autism to request help with difficult tasks

We taught three children diagnosed with autism spectrum disorder to request help using an interrupted chain procedure during which we manipulated task materials such that the child was either incapable or capable of independently completing a link of a behavior chain. We initially observed undesirable generalization of requests for help during capable trials when teaching was introduced during incapable trials for two participants and to a lesser extent for the third participant. However, with repeated exposure to differential prompting and reinforcement across incapable and capable trials, differential responding was observed across EO‐present and EO‐absent trials for all three participants during both teaching sets and one generalization set that was never exposed to teaching procedures. These findings suggest that it is important to consider the antecedent conditions under which the response should occur when teaching children to request help.     

THE EFFECTS OF VIDEO MODELING ON STAFF IMPLEMENTATION OF A PROBLEM‐SOLVING INTERVENTION WITH ADULTS WITH DEVELOPMENTAL DISABILITIES

We investigated the effects of video modeling on the percentage of correctly implemented problem‐solving steps by staff in a group home for adults with developmental disabilities, using a nonconcurrent multiple baseline design across participants. The treatment consisted of staff watching a video model demonstrating the correct implementation of a problem‐solving intervention (i.e., teaching clients to identify problems, possible solutions, and consequences to each solution, and to choose the best solution). The percentage of correctly implemented problem‐solving steps increased for all participants, and the effect was maintained over time, generalized to novel problems, and generalized from role play with a researcher to actual clients.     

Comparing the Effectiveness and Efficiency of Response Repetition to Simultaneous Prompting on Acquisition and Maintenance of Multiplication Facts

This study compared the effectiveness and efficiency of an error-correction procedure, response repetition, to a prompting procedure, simultaneous prompting, on the acquisition and maintenance of multiplication facts for three typically developing 3rd grade students. This study employed an adapted alternating treatments design nested in a multiple probe design across three sets of multiplication facts. Results indicated that correct responding increased upon intervention implementation for all participants. For two participants, response repetition was a more effective teaching procedure. For one participant, while both teaching procedures were effective, response repetition was more efficient in terms of sessions to mastery while simultaneous prompting was more efficient in terms of errors and seconds to mastery. Maintenance data were variable. Discussion focuses on conceptual differences between response repetition and simultaneous prompting that might have accounted for results.     

A Comparison of Simultaneous Prompting and Constant Time Delay Procedures in Teaching State Capitals

This investigation compared the effectiveness and efficiency of constant time delay (CTD) and simultaneous prompting (SP) procedures in teaching discrete social studies facts to 4 high school students with learning and behavior disorders using an adapted alternating treatments design nested within a multiple probe design. The results indicated that both procedures were effective, with the simultaneous prompting procedure being slightly more efficient in terms of errors during instructional and maintenance phases. In addition, when interviewed about their preferences, both the instructor and participants preferred the simultaneous prompting procedure. This investigation extends current research as there are small numbers of studies comparing SP to other response prompting strategies, and to date, SP and CTD have not been compared with high school students with high-incidence disabilities. Future research issues are discussed.
