Reliability, Validity, and Strength of a Unified Model for Information Security Policy Compliance

The purpose of this paper was to first examine the reliability, validity, and strength of a unified model for information security policy compliance that includes eight constructs explaining information security policy compliance. Second, seven hypotheses were developed and tested based on the constructs in the model. An instrument with eight constructs was used to reflect the traditional survey statements method that measures current or retrospective behavior for the items of each construct. A sample of 187 faculty and staff from a mid-sized university in the USA participated in the study. Data were collected electronically and analyzed through SmartPLS 3.0, a partial least square structural equation modeling software. The results indicated strong support for the models' reliability, validity, and strength. The results also showed support for five hypotheses. Two hypotheses were rejected. The findings with implications are discussed. Recommendations for future research are made.
