Ralph and ebvan,I don't completely disagree with either of you.
However,
Be careful with the idea of a "legal diagnosis." Diagnosis are clinical, not legal. Legal terms usually sound like "mental defect" or "incompetent." These are very severe problems that are assessed in the context of a known incident and legal proceding. They are high level concerns that are likely to show up in the BI.
We are playing with some possibly under-informed assumptions about depression and violence risk.
Depression is does not appear to be strongly associated with violence risk, though there are some indicators of increased correleation with intimate partner violence, and addiction, and other things. The picture is not completely clear.
Media incidents are misleading, in that they always report "was being treated for... (depression)" or "was being treated with... (antidepressants)." Which may or may not be accurately interpretable information. Modern antidepressants are effective for a wide range of symptoms, and are generally well-tollerated (minimal side-effects). In the context of an emerging acute or chronic mental health problem, anti-depressant medications will often be first-at-bat, followed by other mood stabilizers, and then the neuroleptics. Antidepressants can sometimes exacerbate a bipolar mood disorder, and mental health professionals are sometimes engaged in "train-catching" problem.
Train-catching problems, involve the avoidance of resource wasting (time), until it is too late and the train is missed (a catastrophic problem). Train-catching is an economic problem, slightly different from the non-catostrophic "news-boy" problem of simply trying to optimize the economic gap and ratio of product cost overhead and lost profits from unsold stuff.
Depression, like (ADD and bipolar disorder), is sometimes regarded as the diagnosis du-jour. A lot of mental health professionals don't like to diagnose people - because it's considered "labeling" (which is considered by some bleeding-heart types to be "bad"). Also, a lot of mental health professionasl are not very good at diagnostic work - it's difficult, especially in the context of differential diagnosis, dual-diagnosis, and medical comorbidity. So, we see a lot of under-diagnosis, and off-label prescribing (in which a doctor uses a depression medication for "stress" without a diagnosis of depression.) Off-label prescribing is not wrong, it's how we learned that some anti-convulsants can help some bipolar patients, how we learned that some anti-hypertensives can reduce intermittent explosive and other reactive anger/agitation problems, and how learned more about the relationship between depression and anxiety.
I'm not sure about any convincing trend in the evidence for depression and gun violence.
Depression is correlated with suicide. One of the highest risk groups, at present, is middle-aged white males, with access to firearms, poor social support, and sudden/unexpected changes in employment/financial/legal circumstances. Suicide prevention efforts have often been directed around teenagers and young adults, because they were considered "at risk." Risk among these groups is visible, because mental health concerns tend to emerge during transitions into and through adolescence, and the transition into adult life.
We are also playing with some possibly un-informed assumptions about psychoticism. The data are actually fairly clear hear. Psychotic persons are at no greater risk for violence than non-psychotic persons. However, psychotic persons with a history of violence are at increased risk for continued violence compared with non-psychotic persons with a history of violence. Again, you have to be careful interpreting these data and findings, because the highest risk group for continued violence, among persons with violence histories, is non-psychotic perpetrators of intimate partner violence.
I agree that the information is interesting.
Keep in mind that a lot of people don't know or don't bother to remember their diagnosis. Other times, professionals aren't real clear with patients about the diagnosis. They may tell the patient that antidepressants are for stress and anxiety. Sure.
It would be better to simply elicit the subject's history of taking medications for any mental health related reasons.
I have no problems with a polygraph examiner asking about a police applicant's history of taking prescription medications, and even about the reasons for those meds. To focus naively on one diagnosis (a vague and misleading one at that) is misguided.
It's up to the psychological evaluator to determine the signal value of the information (medication history and reported reasons), regarding violence risk and police candidacy.
It's also not just about violence risk. It's about training success (training is expensive), and job performance (poor performance is expensive too).
