Background: Recent technology development, miniaturisation and simplification of electronic equipment have made health psychology research more feasible. The aim of this study was to assess usability, practicality and user-friendliness of novel technology aided research using the Technology Acceptance Model (TAM3) as a framework. Methods: We undertook in depth interviews with 12 study participants (Mean age 50.58, SD=9.92; 3M,9F) who had all taken part in research which used mobile-phone/touch-pad aided ecologic momentary assessment, on-line supported activity monitoring and real time on-line administered weight assessment. Qualitative data was analysed using the Framework method. Results: Employing technology in research was seen as useful, practical and accessible. TAM3 variables were often referred to, particularly ‘perceived usefulness’ and ‘perceived ease of use’. Technology was reported as easy to become accustomed to, including among older participants. Discussion: Technology-aided research is seen as valuable and easily embedded in everyday life. TAM3 provides a starting point for conceptualising technology acceptance in health-related behaviour research.
