Lengthening the scale and conducting another pilot is the best choice to increase reliability. It will help to identify which items are contributing to the low reliability and can be revised or removed. Additionally, conducting another pilot will allow testing of the revised scale and the possibility of achieving the desired reliability estimate without administering the scale to a larger number of people or reducing the number of items in the scale.
