The number of dimensions of the construct and the reliability and validity are important factors to consider when deciding between a single-item or multiple-item scale.

Additionally, the reliability and validity of the scale should be considered, as it is important to have a reliable and valid measure regardless of whether it is a single-item or multiple-item scale.
