Rehabilitation and reparation are part of the rights of the torture survivor under the United Nations Convention, yet far less attention is paid to health needs on a national or international basis than to legal and civil claims. Collaborative efforts involving survivors themselves are needed to better understand the usefulness and limitations of existing assessment instruments and treatment methods. Some studies exist, such as that by Elsass et al. who interviewed Tibetan Lamas on the quantification of suffering in scales used to evaluate intervention with Tibetan torture survivors.
