NOTE: This is an unreviewed Preprint

Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note “no longer under consideration” will appear above).

Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a “Peer-Review Me” button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.

Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).

Final version: If our system detects a final peer-reviewed “version of record” (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.

Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.

Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

ABSTRACT

Background:

Telemedicine is both effective and can provide efficient care at lower costs. It also enjoys a high acceptance rate among users. The technology acceptance model proposed is based on the two main concepts of ease of use and perceived usefulness and comprises three dimensions: the individual context, the technological context, and the implementation or organizational context. There is not a short validated questionnaire to check the acceptance of telemedicine services amongst health care professionals using a technology acceptance model.

Objective:

To translate and validate a telemedicine acceptance questionnaire based in the technology acceptance model.

Methods:

The study included the following phases: adaptation and translation of the questionnaire into Catalan, and psychometric validation which include construct (exploratory and confirmatory factor analysis), consistency (Cronbach’s alpha) and stability (test-retest). Factor analysis was used to describe variability amongst observed variables. The Kaiser-Meyer-Olkin test of sampling was adequate (KMO = 0.818) and the Bartlett test of sphericity was significant (Chi-square 424.188; gl=28; P < .001), indicating that the items were appropriate for a factor analysis. The final confirmatory factor analysis conducted showed good fit index (RMSEA = 0.102, CFI = 0.93, TLI =0.90; CD =0.96).

Results:

After removing incomplete responses 144 responses where considered for analysis. The internal consistency measured with the Cronbach’s alpha coefficient was good with an alpha coefficient of 0.84 (95%, CI: 0.79-0.84). The intraclass correlation coefficient was 0.93 (95% CI: 0.852-0.964).

Conclusions:

The questionnaire validated with this study has robust statistical features that potentially make it a good predictive model of professional’s satisfaction with telemedicine programs. Clinical Trial: n/a
