Researcher access to confidential records adds to the vulnerability of workers who participate in workplace studies. inappropriate release of identifiable private information could adversely affect a worker's retention of a job, insurance, or other employment related benefits. to avoid or minimize these risks, the study design must include adequate safeguards to protect the confidentiality of the information collected. a plan for the proper management of study data and records should clearly define: - who will have access to the data.- if the study results, if any, will be included in the employee's personnel records- how the data will be collected and secured- if personal identifiers will be retained and used in the data analysis.- all of above.

The correct answer is E) all of the above.

A plan for the proper management of study data and records should clearly define: Who will have access to the data; if the study results, if any, will be included in the employee's personnel records; how the data will be collected and secured; if personal identifiers will be retained and used in the data analysis.

These elements are very important to maintain the privacy of the information and to make sure to employees that the data collected is secure and only must be used for the research. This way, employees are going to trust and gladly participate in workplace studies. Otherwise, if there are going to be consequences for the worker's answers, many people are going to afraid to cooperate with honests answers.
