Use of a Level System to Improve Synchronous Engagement | BCBA CEU | Learning | 0.5 Hour
In this presentation, Dr. Justin B. LeafĀ describes a study titled The Use of a Level System with Flexible Shaping to Improve Synchronous Engagement. A level system (also referred to as a behavior monitor or clip chart) is framed as a multi-tiered system commonly used in schools and social skills groups. The speaker acknowledges controversy surrounding level systems and notes limited empirical research.
The study evaluated a structured yet flexible level system implemented with two dyads (four children) diagnosed with autism spectrum disorder. The intervention targeted synchronous engagement, defined as both children simultaneously exhibiting favorable affect while engaging in the same activity. Movement within the level system was fluid and based on in-the-moment assessment of synchronous engagement, rather than fixed criteria. No descriptive praise was used so that movement within the level system would function as the primary variable influencing behavior.
An ABAB reversal design was used. During baseline, toys were available but no programmed consequences or level system were present. During intervention, the level system and treasure box contingencies were implemented. Results showed immediate increases in synchronous engagement during intervention phases and decreases during withdrawal phases for both dyads. Treatment integrity was reported at 100%, and interobserver agreement averaged 90%. The speaker concludes that the findings demonstrate the level system, when implemented flexibly and non-punitively, can effectively increase pro-social behavior, while emphasizing the need for additional research.
