Best Practices in Administration
HDQLIFE self-report measures are intended to be completed by the respondent without help from anyone else.
The text and responses of HDQLIFE items cannot be altered in any way and still be considered an HDQLIFE item. If users modify the items, they cannot refer to these modified items as HDQLIFE. There are no data to determine whether or not a modified version would have the same psychometric properties as the original HDQLIFE item. If you do choose to modify items, please clearly specify how the items were modified in any publications or other publicly disseminated products.
IMPORTANT: Please include a citation for any HDQLIFE measures used in publications. If using a short form, please cite the publication describing the development of the full item bank. Citations information can be found HERE.
