Several factors contribute to instrument fatigue in epidemiological research:
Length of the Survey: Longer surveys tend to tire respondents, leading to less thoughtful and rushed responses. Complexity of Questions: Highly complex or confusing questions can cause mental fatigue, reducing the accuracy of responses. Repetitiveness: Repetitive or redundant questions can bore respondents, leading to disengagement. Survey Mode: The mode of survey administration (e.g., online, telephone, face-to-face) can also affect fatigue levels.
