PURPOSE Mood and anxiety disorders are the most common psychiatric conditions seen in primary care, yet they remain underdetected and undertreated. Screening tools can improve detection, but available instruments are limited by the number of disorders assessed. We wanted to assess the feasibility and diagnostic validity of the My Mood Monitor (M-3) checklist, a new, 1-page, patient-rated, 27-item tool developed to screen for multiple psychiatric disorders in primary care.
METHODSWe enrolled a sample of 647 consecutive participants aged 18 years and older who were seeking primary care at an academic family medicine clinic between July 2007 and February 2008. We used a 2-step scoring procedure to make screening more effi cient. The main outcomes measured were the sensitivity and specifi city of the M-3 for major depression, bipolar disorder, any anxiety disorder, and post-traumatic stress disorder (PTSD), a specifi c type of anxiety disorder. Using a split sample technique, analysis proceeded from determination of optimal screening thresholds to assessment of the psychometric properties of the self-report instrument using the determined thresholds. We used the Mini International Neuropsychiatric Interview as the diagnostic standard. Feasibility was assessed with patient and physician exit questionnaires.
RESULTSThe depression module had a sensitivity of 0.84 and a specifi city of 0.80. The bipolar module had a sensitivity of 0.88, and a specifi city of 0.70. The anxiety module had a sensitivity of 0.82 and a specifi city of 0.78, and the PTSD module had a sensitivity of 0.88 and a specifi city of 0.76. As a screen for any psychiatric disorder, sensitivity was 0.83 and specifi city was 0.76. Patients took less than 5 minutes to complete the M-3 in the waiting room, and less than 1% reported not having time to complete it. Eighty-three percent of clinicians reviewed the checklist in 30 or fewer seconds, and 80% thought it was helpful in reviewing patients' emotional health.CONCLUSIONS The M-3 demonstrates utility as a valid, effi cient, and feasible tool for screening multiple common psychiatric illnesses, including bipolar disorder and PTSD, in primary care. Its diagnostic accuracy equals that of currently used single-disorder screens and has the additional benefi t of being combined into a 1-page tool. The M-3 potentially can reduce missed psychiatric diagnoses and facilitate proper treatment of identifi ed cases. prescriptions for mood and anxiety disorders in the United States, 3-5 underrecognition and inadequate treatment of these disorders in primary care practices remain substantial concerns. [5][6][7][8] Tools to improve the identifi cation and management of these disorders are therefore being developed to address this problem. [9][10][11] Despite these efforts, available tools narrowly focus on identifying either depressive or anxiety disorders and provide little guidance for management. Most screening tools target unipolar depression (16.1% prevalence), 12 and they do not help to differentiate unip...
