health officials have been testing machine learning programs that are designed to predict links between certain language markers and health outcomes. These programs could act as an early warning system by scouring social media posts to identify spikes in depression across a given population. <\/p><p>However,  the new findings suggest such AI programs could miss depression in a big slice of the population. If that\u2019s the case, De Choudhury says, \u201cthere are profound public health implications.\u201d<\/p>\n\n\n\n<p>Computer scientist Sunny Rai of the University of Pennsylvania and her team recruited 868 people in the United States for the new study. Half of the participants were Black and half were white, and the two groups were matched by age and gender. Participants completed a standardized online depression survey, the Patient Health Questionnaire 9, and they gave the team access to their Facebook posts. The researchers then fed those social media posts into a text analysis program.<\/p>\n\n\n\n<p>Consistent with earlier work, the use of first-person singular pronouns \u2014 \u201cI,\u201d \u201cme\u201d and \u201cmy\u201d \u2014 increased alongside depression scores for the entire cohort. Conversely, use of first-person plural pronouns, or \u201cwe,\u201d \u201cour\u201d and \u201cus,\u201d was linked to lower depression scores. And as depression scores went up, so too did words reflecting negative emotions, such as those referring to feelings of emptiness and longing, disgust, despair, lack of belonging and self-criticism.<\/p>\n\n\n\n<p>But that picture changed when the researchers broke down responses by race. The text analysis program did relatively well at predicting depression in the white group participants, but did poorly at predicting depression in the Black group. In fact, the program\u2019s ability to predict depression in Black participants was close to zero. Even when the team trained the text analysis program on just Black participants\u2019 social media posts, the program failed to identify any linguistic patterns.\u00a0<\/p>\n\n\n\n<p>\u201cWe re-ran the experiment so many times because we thought we were doing something wrong,\u201d Rai says.<\/p>\n\n\n\n<p>Why the program struggled to predict depression on Black people is unclear, Rai says. Maybe signs of depression in Black people aren\u2019t linked to communication. Or maybe depression links to nonwritten forms of communication, such as changes to body language, rate of speaking or tone. Or maybe the very public nature of social media discourages Black people from sharing too much about how they\u2019re feeling.<\/p>\n\n\n\n<p>It\u2019s even possible that depression lacks universal features, says Ryan Boyd, a psychologist and computational social scientist at Stony Brook University in New York. That would suggest there are flaws in these types of machine learning programs and the information used to train them. For instance, the assumption with this sort of research is that the standardized questionnaire used to measure depression works well, says Boyd, who was not involved in the new study. But mounting evidence suggests that may not be the case, especially with certain populations, such as Black men.<\/p>\n\n\n\n<p>\u201cThe model is only as good as the measurement we are basing it on,\u201d Boyd says.<\/p>\n\n\n\n<p>Sorting out just what is going on requires first determining if social media is a uniquely poor format for studying depression or if Black people\u2019s depression<br\/>does not manifest in speech even in other settings, such as in private conversations with medical staff, Rai says. \u201cWe found this on Facebook, but of course this needs to be replicated \u2026 [outside] a public space.\u201d\u00a0\u00a0 \u00a0\u00a0<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/language-models-depression-black-people-facebook\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>People with depression tend to write and speak about how bad they feel, years of research has shown.
