Measuring the Complexity of Treatment for Challenging Behavior using the Treatment Intensity Rating Form

Area of Science:

• Psychiatry
• Behavioral Science
• Clinical Psychology

Background:

• Challenging behaviors, particularly self-injurious behavior (SIB), often require complex treatment plans.
• Quantifying the intensity and complexity of interventions for SIB is crucial for effective treatment and research.

Purpose of the Study:

• To develop and validate the Treatment Intensity Rating Form (TIRF), a standardized tool for assessing the complexity and intensity of interventions for challenging behaviors.
• To evaluate the TIRF's reliability and face validity in measuring treatment plans.

Main Methods:

• Developed the 10-item TIRF scale assessing pharmacological interventions, behavior supports, and protective equipment.
• Conducted a retrospective review of treatment recommendations for 74 individuals with SIB.
• Compared TIRF scores between individuals with SIB maintained by social reinforcement versus automatic reinforcement.

Main Results:

• The TIRF demonstrated strong inter-rater reliability (98%) and good face validity.
• Individuals with automatically reinforced SIB showed significantly more medication trials (p=0.0005) and required more protective equipment (p=0.0002) compared to those with socially reinforced SIB.
• Antidepressant, antipsychotic, and anticonvulsant medications were utilized, with antidepressants more frequent in automatically reinforced SIB.

Conclusions:

• The TIRF shows initial promise as a reliable measure of treatment plan complexity for challenging behaviors.
• Further research is necessary to fully establish the psychometric properties of the TIRF.
• The findings support the TIRF's utility in differentiating treatment intensity based on the function of SIB.
