Final answer:
The rational method of developing questionnaire items can be time-consuming, expensive, and lead to less reliable results due to participants giving socially desirable or false answers. It captures what people think and believe, but not necessarily how they behave in real life.
Step-by-step explanation:
The rational method of developing questionnaire items can be associated with several problems.
One problem is that it can be time-consuming and expensive to develop and administer questionnaires, especially if a large sample size is needed.
Another problem is that participants may give socially desirable or false answers, rather than honest ones, which can lead to unreliable results.
dditionally, the rational method captures what people think and believe, but not necessarily how they behave in real life.
