The aim of the study was to compare text telephone relay service and videophone relay service. The target group was people borne deaf. The following aspects were investigated: (1) socioeconomic costs, (2) costs of different actors, (3) qualitative aspects of the services, (4) outcomes (intermediate effects and quality of life). The study was longitudinal and measurements were made at three occasions. Data collection was made by post-mailed questionnaires. Of the 41 respondents, 16 persons had access to the text telephone relay service only and 25 persons had access to text telephone relay service supplemented with videophone relay service. The ratings of the quality of the services and the outcomes were significantly higher for videophone relay service than for text telephone relay service (at a 95%-level). The incremental cost was approximately SEK 40 000, or EUR 4 510 (1 EUR = 8.87 SEK, as of 31 December 2000) higher per person and year for the group with access to both text telephone relay service and videophone relay service compared with the group with access to text telephone relay service only.
