Why arent all the items in the RSQ used in creating the four prototype scores?
The additional items in the RSQ can be used to create subscales to assess the attachment dimensions identified by Simpson, Rholes, & Nelligan (1992) and Collins & Read (1990). Thus, researchers are able to relate the RSQ to alternate self-report measures of adult attachment. (see: Griffin & Bartholomew, 1994). Alternatively, and perhaps preferably, you can use the questionnaire to derive scales of the underlying two dimensions. This can be done two ways: 1) by conducting a factor analysis of the items or 2) by using the scores from the four prototype items to create linear combinations representing the self and other-model attachment dimensions. Again, we recommend that you consult the Kurdek (2002) paper in JSPR which recommends the best approach for scoring the RSQ dimensionally.
