Question

Quizplus · Accepted Answer

The placebo effect occurs when participants perceive an improvement in symptoms based on their belief in the effectiveness of the treatment, even if the treatment itself has no actual therapeutic properties. In this case, the strong desire for the new treatment to work may have led to a placebo effect, resulting in participants experiencing pain relief even if the treatment did not actually have a therapeutic effect. This is a threat to internal validity as it creates the possibility that the observed effects may be due to participant expectations or beliefs rather than the actual treatment itself.
