1. Dyadic Sex Differences in Adoptive and Nonadoptive Family Relationships during Emerging Adulthood Amy Walkner-Spaan, M.S.W., L.I.S.W. Martha Rueter, Ph.D.

2. What do we know about adoptive families in emerging adulthood? Retrospectively, adoptees, their siblings, and their parents reported a general level of family closeness (Loehlin, Horn, & Ernst, 2010) Adoptive families reported less warm, supportive communication and increased conflict (Rueter, Keyes, Iacono, & McGue, 2009) Adopted adolescents were observed to have greater conflictual behavior towards their parents (Rueter et al., 2009)

3. Purpose This descriptive research explored relationship differences between adoptive and nonadoptive parent-emerging adult dyads by parent and emerging adult biological sex.

4. Sample Sibling Interaction and Behavior Study (SIBS; McGue, et al., 2007; Rueter et al., 2009) –Families had at least two children –At least one adopted child in the adoptive families For this study: –Eligible emerging adults were 18.50 – 22.49 years old –Eligible mothers and fathers had one child 18.50 – 22.49 years old

5. Sample: Self-Repor t Mom Daughter to Mom Nadopt = 158 N nonadopt = 117 Son to Mom Nadopt = 114 N nonadopt = 84 Mom to Daughter Nadopt = 157 N nonadopt = 114 Mom to Son Nadopt = 114 N nonadopt = 85 Dad Daughter to Dad Nadopt = 155 N nonadopt = 117 Son to Dad Nadopt = 112 N nonadopt = 83 Dad to Daughter Nadopt = 139 N nonadopt = 97 Dad to Son Nadopt = 109 N nonadopt = 73 Emerging Adults M age = 19.83 Mothers M age = 50.43 Fathers M age = 52.69 97% White

6. Sample: Observation Parent Daughter to Parent Nadopt = 158 N nonadopt = 117 Son to Parent Nadopt = 116 N nonadopt = 84 Parent to Daughter Nadopt = 111 N nonadopt = 80 Parent to Son Nadopt = 95 N nonadopt = 59 Emerging Adults M age = 19.82 Parent M age = 50.14 98% White

7. Self-Report Measures Parental Environment Questionnaire (PEQ; Elkins, McGue, & Iacono, 1997) Conflict (12 items) –“ My child and I often get into arguments.” –“My parent and I often get into arguments.” Closeness (12 items) –“My child doesn’t seem to feel very close to me.” –“I don’t feel very close to my parent.” Four dyadic relationship indicators: E.A. - Mother E.A. - Father Mother - E.A. Father - E.A.

8. Independent Observations SIBS Rating Scores (Rueter et al., 2009) Conflict –Hostility scale Closeness –Warmth/Support –Listener Responsiveness –Communication –Prosocial Two dyadic relationship indicators E.A. - Parent Parent – E.A.

9. Results: Self-Report * = p <.05 ** = p <.001

10. Results: Observation * = p <.001

11. Discussion & Future Directions Extends research on adoptive family relationships into emerging adulthood Individuation might affect adopted emerging adults differently Investigate the influence of adoption-specific variables on parent-emerging adult relationships
