O crescimento do número de pessoas atingidas por problema de saúde mental colocou tais distúrbios entre os principais problemas de saúde pública em todo o mundo. Como resultado, aumentou-se a procura por comunidades sobre saúde mental em redes sociais online. Neste artigo, nós caracterizamos a atividade de usuários em comunidades relacionadas à saúde mental no Reddit e analisamos como suas interações através de posts e comentários influenciam no seu estado emocional. Em particular, nós investigamos se a busca por auxílio nestas redes resulta em mudanças nos sentimentos expressos pelos usuários ao longo do tempo. Nossos resultados mostram que os usuários que iniciam discussões nestas comunidades com posts expressando sentimentos negativos, tendem a escrever comentários mais positivos ao final, indicando que o estado emocional dos mesmos pode ter melhorado em decorrência do suporte social provido por estas comunidades. Adicionalmente, propomos modelos preditivos para capturar a variação do tom emocional destes usuários. Nossos modelos poderiam auxiliar nas intervenções promovidas pelos profissionais de saúde para dar suporte aos indivíduos que sofrem de transtornos de saúde mental.
