This Tool Kit was developed by the Economic and Social Commission for Asia and the Pacific (ESCAP) as part of the project 'Building Capacity for Community-based Treatment and Continuing Care of Young Drug Users in the Greater Mekong Subregion'. It aims to provide 'how to do it' guides for assessment of individual, group and family counseling interventions that can be applied in community or residential settings. It uses relevant subregional examples, accessible web-based resources and templates. The Tool Kit comprises seven sections, a CD of useful forms for screening, assessment and follow-up, and a DVD with four videos made by participating project partners.
