Part I: Construct Development and Scale Creation
1) Choose a construct you would like to measure.
The construct will measure the functionality of working memory (WM) at the workplace, with the example of the performance of bookkeeping tasks.
2) Create an operational definition of your construct using at least three peer reviewed journal articles as sources as references.
Since individual’s WM capacities differ not only among people but also between different tasks or settings (Salthouse & Babcock, 1991), measurements should relate to the field of transfer, in this case – performance bookkeeping tasks. Such tasks typically require transfer of data from one medium to another, e.g. from a list to a computer (Carruthers & Espeland, 1991), and WM is typically defined as the quantity of information recalled 30 seconds after the learning phase (Baddeley, 2003). Hence, the operational definition in this domain should focus on the relative amount of pairs of financial data (i.e. name of account and a sum) recalled out of 15 pairs. Continue reading
