In my study an activity checklist is used to measure leisure activity participation of residents, and the activity is assessed in two ways: total number of individual activities and total hours per week. Although the activity checklist has been validated in Hong Kong, it should be clarified whether the instrument is appropriate for residents living in Guangzhou.  I should use the data from the pilot study in Guangzhou to perform a validation. I would like to know how to perform the validation using SPSS. Your great help is highly appreciated. Thanks.
