AP analysis was proposed by David Kenny (Kashy & Kenny, 2000; Cook & Kenny, 2005). This model was created to analyze the mutual influences between the dyad members. Theoretically, it is based on the recognition of the dependency between dyad members, and mathematically it is based on the method for evaluating variance between dyads and within dyads. Can give an investigator much more, than ordinary correlations. First, the model takes into account not individual respondents, but, rather, dyads. Second, it accounts for the mutual influence between dyad members, not only for the correlations between the investigated attributes in the same person. In other words, the model accounts both for intra- and interdyadic variability. Third, it allows determining not only correlations, but also causality or determinants. The purpose of the study was to analyze the correlation between parental traits, children’s traits, and the parent-child relationship, while accounting simultaneously for the intra- and interdyadic variability, as provided for by the Actor-Partner Interdependence Model. There were evaluated the actor and partner effects in real-life dyads: parent-child and spouses. Our sample involved 387 complete two-child families (total – 1,548 people). The mean age mothers 43.08 (SD = 4.22), fathers 45.31 (SD = 6.25). Sibling age was in the range of 11 – 23 years. The mean age of the older siblings was 18.03 (SD = 2.26), the younger siblings were 14.52 (SD = 2.38). The age difference between siblings in one family did not exceed 5 years. Methods Personality. Parents and children assessed Extraversion, Neuroticism (Russian version of the Eysenck Personality Inventory), locus of control and its facets (Russian version of Rotter inventory), sensations seeking and its facets (Russian version of Zuckerman inventory). Parent-child relations assessment. Parents and children completed the self-administered Parent-Child Relationship Questionnaire. The Questionnaire contains two forms: for parents and children. Parents rated their relations with first-born and second-born siblings separately, and both siblings estimate their relationships with mother and father separately. Parents' assessment of the characteristics of relationships with children included 5 indicators obtained by factoring the results of the Questionnaire: Parent-child positive attitude, Control, Softness, Inconsistency, and Trust. The children's assessments of the relationships with parents were received with the children's version of the same questionnaire. Its factorization identified 3 factors: Positive attitude of the parents, Negative attitude, Control, Democratic style. It was shown that the actor and partner effects of the parents, identified on the basis of parental personality traits and parent-child relationships, played a significant role in the variability of personality traits of children. Differences were found in paternal and maternal effects, as well as in the sensitivity of older and younger siblings to these effects. The differences could be interpreted in the context of the role of the shared and nonshared environment in the variability of psychological traits of siblings.
