| Cloud computing is a model for enabling ubiquitous, convenient, on-demand network
access to a shared pool of configurable computing resources including networks,
servers, applications, and services. Our aim in this study was to develop and validate
an instrument to investigate the determinants of cloud computing services (CCSs) based
on Theory of Planned Behavior (TPB). A total of 240 faculty members in a medical
university participated in this cross-sectional study. The development of the Theory of
Planned Behavior-Cloud Computing Services use Questionnaire (TPB-CCSQ) began
with a comprehensive review of literature. Content and construct validity, feasibilityو as
well as reliability were assessed. Exploratory factor analysis indicated an optimal
reduced solution with 30 items and 5 factors. The factors identified included Attitude
toward CCSs use, Perceived Privacy/Security, Perceived Behavioral Control, Intention
to use CCSs and Subjective Norms. The measurement model was found to be with a
good fit to the data in the assumed model, and all sub-scales were found to be significant
within an acceptable range. Our findings demonstrated validity, reliability, simplicity
and functionality of the TPB-CCSQ. Information technology researchers, community
agencies and educational organizations delivering CCSs may apply this instrument as a
practical and useful tool to investigate the cognitive determinants of CCSs. |
