It is not only time for Spring showers and April flowers, but it is also time for Health and Psychosocial Instruments to be Ovid's resource of the month.

Health and Psychosocial Instruments (HaPI)
"Health and Psychosocial Instruments features material on unpublished information-gathering tools for clinicians that are discussed in journal articles, such as questionnaires, interview schedules, tests, checklists, rating and other scales, coding schemes, and projective techniques. Over 2/3 of the tools are in medical and nursing areas such pain measurement, quality of life assessment, and drug efficacy evaluation."

All through April you can try searching HaPI for free (with a registeration)
