The sample Our survey has the objective to investigate the Lebanese banks’ involvement in CSR activities and how these activities are influencing the clients’ behavior. Therefore, the sample involved in this paper’s survey consists of Lebanese banks as well as their clients.In this regard, we elaborated two questionnaires and sub-mitted them to the two groups of respondents. The first group is made of bank officers involved or working in the CSR divi-sion of seven different Lebanese commercial banks. For the sample to be representative of the banking sector, we chose these seven banks from different sizes and categories.As for the second group, it consists of a sample of clients of these seven banks. The number of clients interviewed for each bank varies; ranging from 14 interviewees to 35 interviewees.The latter were randomly selected in the same branch where the bank officer was questioned and on the same date. The total number of clients interviewed is 161 clients.
