Retained articles then underwent full text review for inclusion, following the same steps. Reinforcement systems involves the use of methods to teach children the consequences of engaging in specific behaviors and activities, with the purpose of increasing the likelihood such behaviors will be repeated in the future. Those tokens may then be used in exchange for some desired activity, such as access to a specific toy or computer game, which functions as a backup reinforcer. Despite a significant proportion of studies using rewards for meeting criterions, it is surprising that preference assessments were conducted in very few.

CCD Design Characteristics
All of these techniques focus on antecedents (what happens before a behavior occurs) and on consequences (what happens after the behavior). The person with autism will have many opportunities to learn and practice skills each day. For instance, someone learning to greet others by saying "hello" may get the chance to practice this skill in the classroom with their teacher (planned) and on the playground at recess (naturally occurring). ABA therapy applies our understanding of how behavior works to real situations. The goal is to increase behaviors that are helpful and decrease behaviors that are harmful or affect learning.
Products and services
When the CCD is implemented as an intervention in itself, reinforcement should be effective in shaping behavior if goal-reaching (i.e., automatic reinforcement) is not. Contingencies for reinforcement and punishment were most frequently individual (71.5 %) with the majority of the remaining studies implementing no type of contingency (22.8 %). A small amount of studies used group contingencies (4.5 %) or simultaneous individual and group (1.1 %). Approximately 73.4 % of interventions utilized one or more reinforcement methods and 22.5 % utilized a punishment method; see Table 4 for percentages of reinforcement and punishment methods. A notable number of interventions incorporated reinforcement with another intervention (35.6 %) or used reinforcement alone as an intervention (18.0 %).
A small portion of studies utilized the CCD nontraditionally (i.e., shaped a new behavior or varied materials) which, as discussed, confounds experimental control (Tawney and Gast 1984). As demonstrated by Hall in his early articles, the best use of the CCD is in the dimensional manipulation of behaviors using static methods and behaviors across criterions. One such example is the measure of subject QoL, which, as made evident by this scoping review, was not measured in any study record included, but is of utmost importance to truly indicate the overall long-term impact of ABA.

For example, if the goal is to reduce tantrums when the child has to go to sleep, the parent might reward the child with praise if the child gets ready for bed. The parent would not provide those positive reinforcements if the child threw a tantrum instead. For every behavior where change is desired, the therapist identifies the ABCs—the antecedent, the behavior, and consequence of the behavior.
Rationale for Current Scoping Review
Furthermore, when study records that did not compare to a control or other intervention were excluded, 32 (4%) of the study records remained. These results may indicate gaps in the current ABA research approach, further supporting previous research about the standard of existing ABA literature (Reichow et al., 2018; Smith, 2012). These findings also support recommendations from Smith (2012), suggesting that RCTs comparing ABA to other interventions may be instrumental in evaluating both individual and global changes, as well as revising existing intervention models. Among study records solely studying ASD, the most commonly studied outcomes were language, cognitive, and social/communication, making up 25%, 22%, and 22% respectively. Among these respective outcome measures, 68%, 68%, and 63% reported improvement.
It was also found that no one age group demonstrated improvement when correlated with the number of hours of rendered ABA services (Department of Defense, 2020). This evidence suggests there may be insufficient recent research justifying the need for high-intensity interventions, indicating that more research studies need to be conducted in the field of ABA in terms of assessing ABA impact with different or lower intensity interventions. The gold standard of research is typically denoted as a RCT, followed by CCT or prospective studies. As evident through this scoping review, 64% of all the study records included three or fewer participants, and the median number of participants was three, indicating methods more consistent with SCED.

Applied Behavior Analysis (ABA) is a type of therapy frequently applied to children with autism and other developmental disorders that focuses on imparting skills in specific domains of functioning, such as social skills, communication, academic and learning skills, motor dexterity, hygiene and grooming, and more. Tailored to individual needs, ABA is delivered in a variety of settings, including school, home, clinic, and other community settings. The goal of treatment is to help children function as independently and successfully as possible. An important note in terms of finding appropriate and effective interventions in the treatment for ASD, which is not limited to ABA, is the establishment of standards of care (SoC). Unfortunately, even though there is a wealth of knowledge regarding the assessment, diagnosis and treatment of ASD, there is still no clear SoC for the treatment of ASD (Department of Defense, 2019, 2020).
Family therapy is generally supported as a valuable treatment because it offers emotional support and guidance to parents who will contend with a myriad of services to assist their child. Individual therapy using social story technique and behavioral cue coaching are very useful for the older child/adolescent with Asperger’s syndrome and can make a difference in that child’s acceptance by others. Educational therapy includes intensive one-on-one therapy involving a wide array of techniques focusing on improvement in social, communication, and language skills, and may include ABT. Some children do not speak at all, others speak in limited phrases or conversations, and some have relatively normal language development. Repetitive play skills, resistance to change in routine and inability to share experiences with others, and limited social and motor skills are generally evident.
The features of the CCD suggest its function as a research tool or an intervention tool; however, due to the systematic nature of the CCD, these descriptors become mutually exclusive. If contingencies were removed from step-wise criterions, one could still not rule out sensory consequences as a result of goal reaching in most instances (e.g., automatic reinforcement). In other words, an individual may experience positive feelings in response to meeting a criterion, thus reinforcing the behavior independently from any prescribed reinforcer or reward. Further, if automatic reinforcement were not present in the beginning criterions, it would arguably become a classically conditioned response when paired with contingent reinforcement or punishment. Therefore, this extraneous variable precludes the CCD from being predominantly a research tool and qualifies it as an intervention tool or research/intervention tool or in some circumstances (e.g., self-monitoring) an intervention in and of itself. The benefit of ABT in the absence of clinically significant developmental progress has not been demonstrated in the peer-reviewed published literature.
Again, when the topography or materials are altered from one criterion to the next, as in shaping, experimental control is confounded and a functional relationship cannot be demonstrated (Tawney and Gast 1984). When the level of performance of a behavior, such as student completion of homework, is kept constant though the subject matter changes (e.g., social studies, math), it is important to determine whether the desired action is due to a lack of motivation or skill. In either case, intervention within another design such as a CCD within a multiple baseline design would be more advantageous in demonstrating change.
The opportunity to perform beyond the criterion was available in 190 interventions (71.2 %); however, in five of these interventions participant’s programmed reward was not provided if criterion was exceeded. In 16 cases (6.0 %), this was because the target skill had not been learned (i.e., shaping a new behavior); in 24 cases (9.0 %), procedure data for this variable was not reported. The extent of opportunity to perform beyond criterion (e.g., to final goal, to the next criterion) was not coded as almost no articles reported that detail explicitly. The opportunity to fail to meet criterion was not available in 38 interventions (14.2 %; e.g., hand over hand follow-through or materials not accessible if shaped) and not known in 8 (3.0 %). In total, 62 (23.2 %) cases restricted responding, 42 (15.7 %) excluding studies with shaping which in most cases had not taught the full skill, or changed materials so that previous and future criterions could not be performed. Studies utilizing shaping were excluded from direction and dimension analyses.
Notably, De Luca and Holborn (1992) examined revolutions per minute on an exercise bicycle thru VR reinforcement within a CCD that was found to successfully increase the rate of exercise as each VR range criterion increased. De Luca and Holborn note that gains with the VR schedule inside the CCD were greater than those observed in a similar study which used FR and fixed-interval schedules within a non-CCD design (De Luca and Holborn 1990). Another intervention option that was infrequently utilized was self-management or self-reinforcement strategies such as criterion-setting, independent choosing of reward, delivering or obtaining reward independently, or self-evaluating or monitoring. Use of self-management or self-reinforcement strategies should further reduce resources required for implementation. Further, school-based research has found these strategies to be more effective with greater generalization than teacher-managed interventions (e.g., Fantuzzo et al. 1988) where greater student involvement corresponded with larger intervention effects (Fantuzzo and Polite 1990).
For example, does a specific type of initial criterion (e.g., mean of baseline, highest responding at baseline) or smaller (versus larger) changes in phase magnitude lead more frequently to adherence or success? Further, assessing skilled professional’s fluency in and perceptions of the CCD may provide insight as to why it is infrequently used, though to date its prevalence in applied settings such as schools has not been examined. ABT should be part of person-centered treatment plan that addresses the whole person. The plan is developed based on assessments of the individual’s behavioral, psychological, family, and medical health. The use of ABT begins with a thorough assessment of the individual for whom the treatment is requested.
Unusual responses to sensory information, such as loud noises and lights, are also common. Affected children can exhibit unusual behaviors occasionally or seem shy around others sometimes without having ASD. What sets children with ASD apart is the consistency of their unusual behaviors. Symptoms of the disorder have to be present in all settings, not just at home or at school, and over considerable periods of time.
