The Effective dimension of Applied Behavior Analysis ABA requires that interventions produce socially significant and meaningful changes in behavior In this scenario the primary goal of the intervention was to prepare the child for the flight and enable them to board the plane without severe anxiety Since the child ultimately refused to board due to fear the intervention failed to achieve its intended socially significant outcome Therefore the intervention lacked effectiveness meaning it did not produce the desired meaningful change Lets review why the other options are less likely Behavioral refers to the focus on observable and measurable behaviors The intervention clearly targeted the childs behaviors and responses related to flying eg anxiety refusal to board which are observable Conceptually Systematic means that the intervention is derived from basic principles of behavior analysis and not just a collection of tricks The use of social stories and systematic desensitization techniques are consistent with behavior analytic principles Technological means the procedures are described clearly and concisely enough for replication by others The provided text does not offer enough information to definitively assess whether the intervention was technological While its a critical dimension the direct evidence in the scenario points to the outcome failure which is the domain of effectiveness rather than a lack of procedural detail
