The classic Cook (2000) dataset consists of measurements on security of attachment within families. Only the variable measuring fear of rejection in family relationships is included in this dataset. Cook (2000) deduced this variable from the anxiety dimension of the adult attachment scale (Collins & Read, 1990). The orignial data consisted of four person families (i.e. two parents and two children), but in order to obtain a three person family the oldest sibling is systematically deleted in accordance with Kenny, Kashy & Cook (2006). The following labels are used for the three roles: the mother is labelled "m", the father "f" and the youngest child "y". The data are presented in the long format. Three roles are present: Mothers "m", fathers "f", and the younger child "y".
A data frame with 1249 rows and 5 variables (208 families with 3 members each, round-robin design)
The variables are as follows:
family.id An indicator for the family.
actor.id An indicator of the rater in the dyad, either "m", "f", or "y"
partner.id An indicator for the person being rated in the dyad, either "m", "f", or "y"
anx1: First indicator of relationship specific anxiety (i.e. average of first halve of the scale).
anx2: Second indicator of relationship specific anxiety (i.e. average of second halve of the scale).
