Client Exit Interview surveys are conducted at [MSIA] facilities and sites using a standardized questionnaire. Data collection typically occurs during the fourth quarter of the calendar year, for a minimum duration of two to three weeks, and for up to two months. Data collectors are hired and are trained for a minimum of four days in approaching clients, appropriate informed consent procedures, and the aims of the survey, before beginning data collection at our facilities.

Where it is possible to visit all facilities/sites, a census of sites is taken and a minimum of 107 clients are interviewed. Where it is operationally infeasible to visit all facilities/sites, a stratified cluster sampling design is used, whereby at least 30 sites (which have been sorted by service volume) are randomly selected, and a minimum of 214 clients are interviewed.
