Component analysis of a self‐monitoring intervention for increasing task engagement for individuals with developmental disabilities

Leif et al. (2026) asked a simple question: does self-monitoring alone make kids stay on task, or do you need to add rewards?

They worked with children who had intellectual or developmental disabilities. Each child first tried plain self-monitoring—checking off if they were working. Later, the team added small rewards for real engagement. They tracked task engagement minute by minute.

Self-monitoring by itself did almost nothing. Engagement stayed low.

When the teacher started giving points and praise for actual on-task behavior, engagement jumped—even after the check-off sheet was taken away. The reward piece, not the checklist, drove the change.

Rosenbloom et al. (2019), Strang et al. (2017), and Fiene et al. (2015) all saw big gains with self-monitoring alone. Their students used iPads, smartwatches, or self-graphing sheets and no extra prizes were needed. Looks like a clash, but the tools were different: tech gave instant beeps, pictures, or vibrations that acted like tiny built-in rewards. Paper and pencil did not.

Herrnstein et al. (1979) also got good results with plain self-monitoring, yet their kids were neurotypical and highly verbal. Leif’s students had more significant delays, so they may need stronger motivation.

Einfeld et al. (1995) ran a similar component test and likewise found that adding rewards turned a weak self-rating system into a powerful one. The pattern repeats: self-evaluation sets the stage, but reinforcement steals the show.

If you hand a child a self-monitoring sheet and walk away, don’t expect magic. Pair the sheet with immediate praise, tokens, or brief breaks for real engagement, then fade the sheet once the behavior is strong. Tech tools can help, yet always check that some form of reward is in play—especially for learners with intellectual disability.
