ABSTRACT
Research on programs and public policy can be enhanced by the interactions among investigators. Nowhere is the need for multiple researchers more apparent than in conducting a needs assessment. To identify needs, describe who has the needs, and document the availability of services and programs require accessing different sources of information using different research skills. A perceived need is anything people consciously lack and desire. An expressed need is a perceived need that is given voice. Normative needs are based on a professional assessment or knowledge. A comparative need is based on others who receive a service. While Bradshaw's typology identifies perceived, expressed, normative, and comparative needs, it is worth mentioning a fifth need, conflicting needs. To identify perceived needs and learn more about the quality and accessibility of services we may want to interview clients or potential clients. Potential interview subjects could include mentally ill persons, released prisoners, or pregnant teenagers.
