used for diagnosing bipolar disorder. He also co-developed the Patient Health Questionnaire (PRIME-MD) which can be self-administered to find out if one has a mental illness. The portions of PRIME-MD directed at depression (PHQ2 and PHQ9) have since become accepted in primary care medicine for screening and diagnosis of major depression as well as for monitoring response to treatment. Position on the Diagnostic and Statistical Manual of Mental Disorders In 1974, Spitzer became the chair of the American Psychiatric Association's task force of the third edition of the Diagnostic and Statistical Manual of Mental Disorders, the so-called DSM-III, which was released in 1980. Spitzer is a major architect of the modern classification of mental disorders, which involves classifying mental disorders in discrete categories with specified diagnostic criteria; however, he later criticized what he saw as errors and excesses in the DSM's later versions, although he maintained his position that the DSM is still better than the alternatives. In 2003, Spitzer co-authored a position paper with DSM-IV editor Michael First, stating that the "DSM is generally viewed as clinically useful" based on surveys from practicing professionals and feedback from medical students and residents, but that primary care physicians find the DSM too complicated for their use. The authors emphasized that given then-current limitations in understanding psychiatric disorders, a multitude of DSM codes/diagnoses might apply to some patients, but that it would be a "total speculation" to assign a single diagnosis to a patient. The authors rejected calls to adopt the ICD-9 because it lacked diagnostic criteria and would "[set] psychiatry back 30 years," while the ICD-10, closely resembled the DSM-III-R classification. In 2013, a definitive autobiography of Spitzer, The Making of DSM-III: A Diagnostic Manual's Conquest of American Psychiatry, was published by author and historian Hannah S. Decker. Spitzer was briefly featured in the 2007 BBC TV series The Trap, in which he stated that the DSM, by operationalizing the definitions of mental disorders while paying little attention to the context in which the symptoms occur, may have medicalized the normal human experiences of a significant number of people. In 2008, Spitzer had criticized the revision process of the DSM-5 for lacking transparency. He has also criticized specific proposals, like the proposed introduction of the psychosis risk syndrome for people who have mild symptoms found in psychotic disorders. On homosexuality Spitzer led a successful effort, in 1973, to stop treating homosexuality
