Data Collection

As a part of our ongoing commitment to provide reliable and valid instruments, MHS relies on our community to collect representative data for new and revised assessments. We are looking for qualified professionals and researchers with access to child and adult populations.

In addition to receiving compensation for your participation, you will gain access to groundbreaking assessment tools prior to publication. All respondent information is kept confidential and personal information is removed prior to analyses.

Your help allows us to maintain the high standards and quality MHS strives for.
