The investigative techniques used for the current research were based on Rapid Assessment Methodology (RAM), which is being used increasingly to assist decision making about appropriate interventions for social problems. RAM draws on a range of research techniques that have been adapted from applied anthropological, sociological, and evaluation methods, so that they can be applied within a rapid time frame and generate relevant information at relatively low cost in circumscribed geographical areas. Various combinations of research tools have been developed and used in RAM. These have generally included identification, examination and analysis of existing quantitative "indicator" data, "key informant" interviews, direct observation, and focus group discussions. The current research project aimed to develop a RAM that would permit the gathering of valid and reliable research data on amphetamine use within a rapid time frame and at relatively low cost. A three-stage model of rapid assessment was developed in which each stage was used to inform subsequent stages. The RAM was implemented in the Adelaide metropolitan region of South Australia and in a rural regional center. Stage 1 consisted of consultant interviews and indicator data; stage 2 consisted of a survey of current amphetamine users; and stage 3 involved focus group interviews. The study was conducted within 4 months with minimal staff. The results have been used to inform the development of an intervention program to respond to hazardous and harmful use of amphetamines. 27 references
