Triads consisting of father, mother, and an offspring from 122 intact families responded to the Dreger Dyadic Family Interaction Scale (DDFIS) and the Marlowe-Crowne Social Desirability Scale. The sample was made up of mostly white, middle-class, non-clinic families. Two offspring age-groups were included, 12-14 and 18-21. Factor analysis on the DDFIS yielded ten factors. Analyses of variance comparing subgroups within the samples indicated many findings consistent with existing literature or in the expected direction. There were also unexpected findings. Another two independent groups of college students were asked to rate the wholesomeness and the social desirability of the DDFIS items. There was no significant difference between the two sets of rating. It was concluded that the DDFIS merits further investigation. The questionnaire exhibits satisfactory internal consistency and the reliabilities of most factors are in the adequate range. There are also indications of construct validity. The questionnaire is not unduly influenced by social desirability tendencies. Means for each item, dyads, family, and overall as well as deciles for dyads and family are given. Standardized factor scores by dyads are also given. The relations between social desirability and wholesomeness were discussed.
