Treatment integrity is a critical component to evaluating the impact of interventions (Collier-Meek et al., 2018). However, one frequently underreported and unacknowledged dimension of treatment integrity is intervention dosage. Determining the amount of treatment (i.e., dosage) necessary to produce desired changes is important to increasing our understanding of the impact of an intervention and the development of a more efficient and precise method of organizing and delivering treatments (Codding et al., 2016). Utilizing data (n = 391) from four individual randomized control trials and three clustered randomized control trials, the purpose of the present study was to descriptively examine the dosage of a performance feedback intervention implemented among seven cohorts of third-grade students, as well as examine the relationship between the amount of intervention dosage received and students' writing productivity. Results of this study found that for every intervention session received, students wrote approximately two more words, which was considered a statistically significant outcome (p < 0.001).
