Scoop.it ShareThis

The MRC National Survey of Health of Development (NSHD) assessed their cohort members (CMs) during the study’s age 43 sweep using the Motor Speed and Praxis measure.

Details on this measure and the data collected from the CMs are outlined in the table below.

Domain:Motor skills
Measures:Psychomotor speed
Manual dexterity
Control precision
CHC:Gp (psychomotor abilities)
Administration method:Research nurse; face to face; physical task
Procedure:Participants were presented with a set of pegs that were placed in holes on one side of a wooden board. They were then timed as they moved 10 the pegs from one hole to an adjacent hole on the opposite side. Five trials were conducted for each hand (10 trials total).

Item-level variable(s):PGL189 - PGR589
Total score/derived variable(s):PEG89
Descriptives:Raw score

Age of participants (months):Mean = 521.84, SD = 2.19, Range = 514 - 533
Other sweep and/or cohort:None
Source:This task was developed specifically for this study. Similar manual dexterity tasks have been used as screeners for manual dexterity difficulties since the 1940s, e.g. Tiffin and Asher (1948).
