Why Collect Measures?

Measurement standardization is an important part of a mature science.

RelaScale answers recent calls for the discipline of psychology to document and standardize its measures.[1][2] By curating a publicly available collection of measures for the field of relationship science, we hope that RelaScale can help to:

  1. improve measurement consistency across studies
  2. combat the proliferation of constructs and measures
  3. facilitate meta-scientific projects
  4. encourage the iterative improvement of the field’s measures

Ultimately, the goal of RelaScale is to help make close relationships research more cumulative.

Access Form (Password Required) Request Access

If you have a validated self-report measure pertaining to interpersonal relationships, we invite you to add it to the repository by completing a short form.

What’s in the form?

The form will ask you for some basic information about your measure, such as the construct(s) it represents, its publication reference, its subscales or dimensions, and its number of items.

We will also ask you to grant other researchers permission to use your scale by selecting a copyright license option for it. Finally, we will require a document containing the verbatim wording of the scale (e.g., as a word doc or a pdf). This should be your own personal copy of the scale - the version you would use in your research, for example.

Once you have submitted the form, a moderator will review and approve your submission. Please note that at this time, only published self-report measures are eligible for inclusion in the repository.

If you’ve already obtained the password from an administrator (e.g., at a conference presentation), you may access the form using the direct link. Otherwise, please request access to the form.
