I just noticed a study from earlier in the year that sought to understand what impact getting treatment had in suicide prevention for lesbian, gay, and bisexual people. The results aren't what the researchers expected, so there there will be more work to understand the forces at work here.

Here's the citation:
Meyer, I. H., Teylan, M. and Schwartz, S. (2014), The Role of Help-Seeking in Preventing Suicide Attempts among Lesbians, Gay Men, and Bisexuals. Suicide and Life-Threat Behavi. doi: 10.1111/sltb.12104

Quote:
The study finds that seeking treatment from a mental health or medical provider did not reduce the odds of a suicide attempt. Respondents who sought mental health or medical treatment at some time prior to their suicide attempt (or, among those who did not attempt suicide, prior to the age when suicide might have been attempted) were as likely as respondents who did not seek any mental health treatment to have a suicide attempt or serious suicide attempt after this time. However, counseling from a religious or spiritual advisor was associated with worse outcomes. Compared with individuals who did not seek help at all, those who sought help from a religious or spiritual advisor were more likely later to attempt suicide.

“The findings are troubling because seeking treatment is a recommended suicide prevention strategy and this study’s results show no more positive effect for people who sought treatment. More troubling is the finding that individuals who sought religious or spiritual treatment had higher odds of later attempting suicide than those who did not seek treatment at all,” said co-author Ilan H. Meyer, Ph.D., Williams Senior Scholar of Public Policy.

Clearly we need better interventions than we have today to drive these numbers in the right direction.
