Which of the following is a limitation of the Hamilton Anxiety Rating Scale (HAM-A)?

Choice A reason: The HAM-A is widely criticized because it lacks specific items to assess "anxious expectation" or "worry," which are the core diagnostic requirements for Generalized Anxiety Disorder (GAD) according to the DSM. It focuses heavily on somatic and autonomic symptoms rather than the cognitive-affective process of pathological worrying. Choice B reason: This statement is incorrect as the Hamilton Anxiety Rating Scale (HAM-A) consists of 14 items, not 7. Each item is scored on a scale of 0 to 4. A scale with only 7 questions would be the GAD-7, which is a different instrument entirely used for screening anxiety. Choice C reason: The HAM-A actually does include items related to cognitive symptoms, such as "anxious mood" (worries, anticipation of the worst) and "intellectual" (difficulty in concentration, poor memory). Therefore, claiming it lacks cognitive symptoms is factually incorrect regarding the structure of the 14-item validated assessment tool. Choice D reason: One of the primary uses of the HAM-A is precisely to monitor the response to treatment in clinical trials and practice. It is sensitive to change, allowing clinicians to compare total scores over time to determine if a patient's anxiety levels are decreasing following therapeutic or pharmacological interventions.
