Latasha's family is concerned that she is showing signs of an eating disorder. She recently met with a therapist for the first time, and this is her description of the encounter: I was told to keep a diary for the next 2 weeks to record the following: how many calories I consume at each meal or snack, any episodes of binge eating or purging I have, thoughts about eating and purging, and the amount of exercise I get. 

1. What assessment method does Latasha's experience characterize?
2. What is the intended purpose specific to the type of assessment Latasha experienced?
