Items are sorted by decreasing difficulty from top to bottom. Higher logit and % (of full scale) values indicate more difficult activities. SE: standard error; Prob. χ²: probability of the chi-square.

activities also included in ABILHAND-Kids (8).

The most frequently reported experts’ opinion is presented. 1 indicates unimanual activities; 2 indicates bimanual activities manageable in several unimanual steps (2A), requiring stabilization with 1 hand and digital activity with the other (2B), requiring digital activity from both hands (2C).

XX indicates a stabilization of both hands and (X) indicates that it depends on the contextual factors of the activities (e.g., “Removing an unzipped jacket or coat” may require more or less strength depending on the child’s age and the jacket or coat weight; “Brushing or combing one’s hair” may require more or less precision and strength depending on the hair length and hair entangling).
