Subclaims¶

q3 i? The System Usability Scale median score for KOKU was 88.75 (IQR 77.50, 100.00), exceeding the >80 cut-point for excellent usability, and general acceptability on the theoretical framework of acceptability was high (mean 4.64, SD 0.48). → French Chloe 2026

q3 · i? · the article prints no effect size for this finding · causal · r3

Descriptive summarisation of usability and acceptability questionnaires completed by intervention-group participants at 12 weeks, with SUS scores compared against the industry average of 68 and the >80 excellent-usability cut-point; user experience was also rated excellent across pragmatic and hedonic quality.

"Results from the SUS show that KOKU had excellent usability (median score 88.75, inter-quartile range (IQR): 77.50, 100.00, n = 90). The seven constructs of the TFA were also considered, and general acceptability was high (mean score 4.64; SD: 0.48)."
