Participants will be selected by sampling method and after obtaining an informed consent, they will be randomly assigned to two intervention and control groups.
Simple random assignment will be used to assign the samples to the two groups. For this purpose, the researcher will first perform randomization using web-based randomization (using the Research Randomizer site) and enter study information, including the number of groups and the number of samples in each group, so that companies will be assigned to the intervention or control group, respectively.
Allocation concealment will be done using opaque, sealed, and randomly sequenced envelopes. The goal of this method is that the participant and the researcher do not know the assigned group (test or control) before opening the envelope. In this regard, the supervisor, as a third party and without the researcher's involvement in the allocation process, will place the codes and assigned group in a total of 68 envelopes according to the randomization list prepared in the previous step, and the envelopes will be closed and sealed after entering the information. At the time of allocation, each caregiver receives an envelope and, after opening it, announces the name of their group to the researcher; then, the researcher will register them in the test or control group list according to the allocation result.
