q2 · i? · quant-synthesis · r2

Meta-analysis of 23 single-subject design studies (78 participants, 140 observed cases) calculating PND per observed case. The mean PND of 91.8 and median of 100 exceed the very effective threshold; treatment-phase mean was 88.6, maintenance 99.8, generalization 100.0.

"The average PND score of 140 observed cases was 91.8, which means mobile device-based intervention was a very effective intervention for individuals with ID."

• PND outcomes were not significantly affected by participant characteristics, device types/functions, intervention strategies, or target skill types — related
• Conducting maintenance and generalization phases was significantly associated with higher PND scores than treatment-only cases — related
• Employment of a mastery criterion was positively associated with PND scores (τ = .168, p = .023) — related
