The present study examines the outputs and qualities of the thirteen teen pregnancy service hotlines in Taiwan that were funded by the Children's Bureau in 2004 and 2005. The evaluation was made through agency visits, focus groups, document reviews, call-in tests and the use of a management information system. The results show that the average number of calls was low, and one agency did not receive any calls during the time period examined. The quality of services varied, and the advice provided by the hotline staff was influenced by the value orientation of the agencies. Most callers were adult women, and the major services they received were information and emotional support. The service characteristics were heavily affected by the goals and routine tasks of the agencies as certain agencies applied their existing services to the program without assessing their fitness to the needs of the potential clients. Suggestions for service improvement are provided, including an islandwide hotline to be set up and operated by a single agency with high accountability. Implications for program monitoring and documentation, staff training and knowledge-sharing, and service advertisement and promotion are also discussed.
