Teaching self-catheterization skills to children with neurogenic bladder complications.

Two girls with spina bifida needed to learn clean intermittent self-catheterization. The authors built a doll with a small hole in the lower belly. A mirror let each girl watch her hands while she practiced every step on the doll.

The trainer used behavioral skills training: explain, model, practice, feedback. They tracked each step with a multiple-baseline design across the two children.

Both girls reached 100 % correct steps on the doll after only four to six short sessions. When they switched to their own bodies, they kept scoring 100 %. One girl kept the skill for at least three months with no extra teaching.

The mirror plus doll setup cut the usual teaching time in half compared with clinic reports from the same hospital.

Jason et al. (1985) taught multihandicapped preschoolers to start play with peers. Both studies used the same multiple-baseline BST recipe, but the 1985 team used live peers while the 1989 team used a doll. Same method, different tool.

Diz et al. (2011) gave kids with hemiparetic CP a mirror view of the non-moving limb to fix position sense. Mirror feedback helped in both papers, but P et al. aimed at proprioception while A et al. aimed at step-by-step skill. The mirror works for both body-awareness and task-learning.

Pitetti et al. (2007) ran a multiple-baseline BST study for math in foster homes. Again, the design matches, yet the 2007 paper used peer tutors and the 1989 paper used a doll. Together they show BST travels across academic, social, and medical self-care goals.

If you teach catheterization, start with a doll and a mirror. You save embarrassment, reduce infection risk, and need fewer live trials. The same trick can work for other private medical tasks like insulin injections or central-line flushing. One cheap doll and a hand mirror can cut your teaching time from weeks to days.
