Common use of Existing Instruments Clause in Contracts

Existing Instruments. Knowledge about user satisfaction with the SDP should be generated from data collected with valid and reliable instruments (Xxxxxxxx and Xxxxxx, 2008). A recent literature review based on searches in the CINAHL, Pubmed and Cochrane databases revealed only one instrument constructed to assess satisfaction with the assistive technology, i.e. the device and the SDP, namely the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST 2.0) (Xxxxxx, Xxxxx-Xxxxxxx, Ska, 1996). The SDP part of the QUEST 2.0 consists of four items and has some experienced-based limitations, e.g. that the four QUEST 2.0 service items require a different timing of when the users should be asked, and that a ‘does not know’ response alternative is not included (Wressle and Xxxxxxxxxx, 2004; Xxxxxx, 2005; Xxxxxxxxxx and Wressle, 2008). Besides, some authors have criticized the QUEST 2.0 for providing too little detailed information to really support quality development of the services (Xxxx, 2004; Xxxxxx, 2005).
