Subclaims¶

q3 i? The change in rate between the intervention and maintenance slopes was −4.39, a statistically significant difference, indicating a slight decline in fidelity after training. → Joelle Fingerhut and Mariola Moeyaert 2022 q2 i? When accounting for outliers (n = 14), no difference in implementation fidelity during maintenance phases appeared. → Joelle Fingerhut and Mariola Moeyaert 2022 (2)

q3 · i? · quant-synthesis · r2

HLM analysis (Model 1) of maintenance phases, which occurred 4 to 224 days after the last intervention session among 51 (23%) participants. The article reports "−4.39, γ̂200 = −4.39, t(3399) = −2.86, p < .025", a significant slope difference.

"The change in rate between the slope of the intervention phase and the slope of the maintenance phase was −4.39, γ̂200 = −4.39, t(3399) = −2.86, p < .025."

q2 · i? · quant-synthesis · r2

The authors' outlier analysis, using the interquartile range method they describe, found no apparent maintenance difference once 14 outliers were excluded; this is an author-reported descriptive result.

"However, when accounting for outliers (n = 14), there does not appear to be a difference in DTT implementation fidelity during maintenance phases (e.g., 30 days later)."

Discussion¶

Related Claims¶

• Behavioral skills training and other trainings raise DTT implementation fidelity from a low baseline of 40.61% to over 90% accuracy by the end of training — related
• In a meta-analysis of single-case studies, participants trained with complete behavioral skills training had significantly higher DTT implementation fidelity than those trained with only one, two, or three BST components — related
• DTT implementation fidelity declines slightly after training ends, with a statistically significant difference between intervention and maintenance slopes — possibly the same claim (merge candidate)
• DTT implementation accuracy increases by 1.33 with each additional observation during the intervention phase — related
