Sampling Procedures and Sample Size
The number of police officers who were involved in the study was determined using Kothari‟s (2004) recommendations that one third of the total population is considered representative of the population. Given that there were 269 police officers in the division, the number of police officers (n) who participated in the study was 91. Stratified sampling techniques were used in order to ensure that all the stations, posts and all the police ranks are represented. The number of respondents from the police station and posts was determined using proportionate sampling. At the station and post level, those who participated in the study were chosen using simple random sampling procedures. The OCPD and all the 3 OCSs were selected using purposively sampling techniques. Mugenda and Mugenda (2007) contend that purposive sampling allows a researcher get information from those who are in the position to provide it. The OCPD and OCS are the appropriate people to provide information on work performance of police officers and strategies to deal with occupation stress as they are in charge of their arrears of jurisdictions. The distribution of the sample is summarized in table 4
