Do hospital physicians' attitudes change during PACS implementation? A cross-sectional acceptance study.

Purpose: The purpose of this study is to gain a better insight into the reasons why hospital physicians accept and use a Picture Archiving and Communication System (PACS). Two research questions are put forward, pertaining to (1) factors that contribute to physicians' acceptance of PACS, and (2) whether these factors change as physicians gain experience in using PACS.

Methods: Questionnaires were administered at three moments in time during the PACS implementation process in a private hospital: just before its introduction (T1), four months later (T2), and about fifteen months after the introduction of PACS (T3).

Differences between general computer attitudes and perceived computer attributes: development and validation of a scale.

The aim of this study was to develop a tool for measuring individuals' dispositions toward the use of computers in their work environment. The study reports the construction and validation of a general computer attitude and perceived computer attribute scale. Exploratory factor analytical evidence with a sample of 381 employees indicated a structure underpinned by two constructs, an attitudinal factor and a perceived computer attribute factor.
