A 24-year-old woman presents to the PMHNP for a psychiatric evaluation with a chief complaint of depression. Upon questioning, the client states that during certain periods of time, she has needed little sleep but still felt energetic. She has had "creative spurts” during these periods, during which she has started new projects, such as home decorating and writing a book. Which of the following assessment tools will the PMHNP use to assist in diagnosis?

Choice A reason: The Observer-Rated Scale for Mania is used by clinicians to assess manic symptoms but is less practical for initial self-reported screening in outpatient settings. Choice B reason: The Mood Disorders Questionnaire (MDQ) is a self-report screening tool designed to identify symptoms of bipolar disorder, including periods of elevated mood and increased energy, making it appropriate for this patient’s history. Choice C reason: The PHQ-9 assesses depressive symptoms but does not screen for hypomanic or manic episodes. Choice D reason: The Young Mania Rating Scale (YMRS) is used for rating current manic severity but is not a screening tool for past hypomanic or manic episodes.
