1. Genetics, Families, & Social Development: The Important Contributions of Adoptive Families Half-Day Conference for Adoptive Families and Professionals Spence-Chapin New York April 18, 2008 Jenae Neiderhiser, Ph.D. The Pennsylvania State University Leslie Leve, Ph.D. Oregon Social Learning Center

2. Workshop Outline I. Overview of Genetics II. Description of the Early Growth & Development Study (and family of studies) III. Early Results from EGDS IV. Implications for Prevention and Services for Adoptive Families

3. I. Overview of Genetics Developmental Behavior Genetics Behavior genetics: Exploration of the potential influence of genes and experience upon a behavior Focus: Individual differences & the similarity (covariance) of relatives Research Strategies: Twin studies, Family studies, & Adoption studies (and combinations)

4. Individual Differences: Concerned with differences among individuals within a population e.g. How does antisocial behavior differ in a population of teenagers? Group Differences: Concerned with differences between groups within a population e.g. How do teenage boys and girls differ for antisocial behavior?

5. Estimating genetic & environmental influences Examine family members who differ in degree of genetic relatedness Examine family members who differ in degree of genetic relatedness identical twins, fraternal twins, parent-biological child, adoptive parent-adopted child identical twins, fraternal twins, parent-biological child, adoptive parent-adopted child Compare similarity in family members (correlations) Compare similarity in family members (correlations)

6. Genetic influences Genetic influences Indicated by increased similarity for increased genetic relatedness Indicated by increased similarity for increased genetic relatedness MZ twins > DZ twins > adopted siblings MZ twins > DZ twins > adopted siblings Shared environmental influences Shared environmental influences Indicated by within-family similarity Indicated by within-family similarity ANY similarity in adopted siblings or between adopted children & their adoptive parents ANY similarity in adopted siblings or between adopted children & their adoptive parents Nonshared environmental influences Nonshared environmental influences Indicated by differences in family members Indicated by differences in family members ANY differences between MZ twins ANY differences between MZ twins

7. Covariance of Relatives GEsEn Identical Twins1.0 0 Fraternal Twins.501.00 Full Siblings.501.00 Adoptive Siblings01.00 Birth Parent-Child.5000 Adoptive Parent-Child01.00

8. Heritability: Proportion of total variance that can be explained by genetic differences in individuals in that population Environmentality: Proportion of total variance that can be explained by nongenetic (environmental) differences in individuals in that population Shared environment – all nongenetic influences that make family members similar to one another Nonshared environment – all nongenetic influences that make family members different from one another

9. Important Points about genetic and environmental influences Heritability does not equal immutability – it can be changed and modified by the environment Heritability can, and does, change over time There is a large amount of variation that is not due to genetic factors

10. “Genetic influence” on a phenotype does not imply: -the environment is unimportant -genetic determinism, or even a close relationship between genes & behavior Environmental influences are all nongenetic influences that contribute to individual differences May include: prenatal effects, environmental influences on DNA, traditional environmental factors (parenting, neighborhood, SES, etc.)

11. Patterns of Genetic & Environmental Influences Wide range of behaviors have been examined across the lifespan Physical characteristics (height/weight) Physical characteristics (height/weight) Personality & temperament Personality & temperament Mental health & psychopathology Mental health & psychopathology Social relationships & behavior Social relationships & behavior

12. Sample Twin Correlations

13. Genetic and Environmental Influences on Psychological Traits

14. Genetic and Environmental Influences on Interpersonal Relationships

15. General patterns of genetic & environmental influences on interpersonal relationships most salient for children & adolescents Parenting Warmth/Support & Conflict/Negativity Warmth/Support & Conflict/Negativity Tend to show genetic influences Tend to show genetic influences Monitoring & Control Monitoring & Control Tend to show shared environmental influences Tend to show shared environmental influences Sibling relationships Mostly reciprocal in nature  due to shared environmental influences Mostly reciprocal in nature  due to shared environmental influences Peer relationships Vary by construct, generally due to genetic & shared environmental influences Vary by construct, generally due to genetic & shared environmental influences

16. How can we understand genetic influences on “environmental” measures and interpersonal relationships? Passive Genotype-Environment Correlation Parent Temperament Parenting Behavior and/or Parent-Child Relationship GPGP GcGc.50

17. How can we understand genetic influences on “environmental” measures and interpersonal relationships? Evocative Genotype-Environment Correlations parent influences child evokes Parental CONFLICT/NEG FAMILY EFFECTS Child behavioral CHARACTERISTICS CHILD EFFECTS GCGC

18. Direction of effects: Child to parent (evocative rGE) Parent to child (passive rGE or E) What are the mechanisms of the environment’s influence on child outcomes? Why do we care?

51. III. EGDS results related to adoption Openness Agency satisfaction and services How adoption has affected aspects of your life

52. What was the level of openness in the adoption? 1-7 rating of the level of openness in the adoption

53. Openness Most families continue to report a moderate level of openness throughout toddlerhood (periodic phone contact, visits, or mail exchanges) Openness decreased somewhat over time according to adoptive mothers, adoptive father, birth mothers, and birth fathers. For example, at 9-months of age, 59% of adoptive mothers rated the adoption as “open” or “very open”. This decreased to 56% at 18-months, and 54% at 27- months.

54. How satisfied are adoptive families with the level of openness? 1-4 rating of the level of satisfaction (very satisfied  very dissatisfied in the level of openness in the adoption) Most families continue to report a high level of satisfaction with the level of openness throughout toddlerhood Satisfaction also decreased steadily over time according to adoptive mothers, adoptive father, birth mothers, and birth fathers. For example, at 9-months of age, 69% of adoptive fathers were “very satisfied” with the openness. This decreased to 63% at 18-months, and 53% at 27-months.

55. How would adoptive mothers change openness? 9-months 18-months 27-months

56. How would adoptive fathers change openness? 9-months 18-months 27-months

57. What does openness relate to? Adoptive mother, adoptive fathers, and birth mothers agree very strongly about the level of openness in the adoption, about the amount of contact, and about the amount of knowledge between parties Higher levels of openness are related to adoptive mothers’ and fathers’ increased satisfaction with the adoption process Higher levels of openness are related to birth mothers’ and birth fathers’ increased satisfaction with the adoption process and positive adjustment Ge et al., J. of Family Psychology, in press

58. How satisfied are adoptive mothers with the information they have about the birth parents? (very stable; numbers here are at 27-months) Birth Mothers Birth Fathers

59. How satisfied are adoptive fathers with the information they have about the birth parents? (very stable; numbers here are at 27-months) Birth Mothers Birth Fathers

60. Why did the adoptive family select their agency? On average, adoptive families looked at 3-4 agencies before selecting the one they used. The primary deciding factors were: The agency’s philosophy about adoption, including openness, and the agency mission statement (83%) The information received about the adoption agency from a packet, website, or meeting (69%) Other people’s recommendation, word of mouth, or agency reputation (68%) Geographic location of the agency (53%) Agency staff (50%)

61. Why did the birth mother select their agency? On average, birth mothers looked at about 2 agencies before selecting the one they used. The primary deciding factors were: The agency’s philosophy about adoption, including openness, and the agency mission statement (68%) The information received about the adoption agency from a packet, website, or meeting (64%) Services offered, such as counseling, meeting other birth parents, or support group (50%) Other people’s recommendation, word of mouth, or agency reputation (47%) Agency staff (45%)

62. Satisfaction (‘very’ or ‘somewhat’) with services The information agency provided about adoption process (96%) Education and support services (90%) Ability to make recommendations for outside services like counseling (89%) Staff responsiveness to requests (88%) Skill of the staff (92%) Policy about openness (98%) Home study process, including the length of time it took to complete it (95%) Matching process (95%) Placement process (94%) Post placement services (91%)

63. Agency services that were most helpful The matching/placement process Educational classes Orientation workshop Specific social worker/staff member Availability and support of agency staff Counseling Mediation with birth mother

64. Services sought outside of the agency Legal services (19%) Home study from a different agency (7%) Infant care/parenting classes (4%) Support group (4%) Counseling (3%)

65. The most difficult part of the adoption process Waiting for a child Coming to the decision to adopt The adoption process General adjustment to new child (lack of sleep, siblings) Coming to terms with infertility issues Adoption paperwork Cost Dealing with a failed adoption(s)

66. Nicest or most important thing someone did during the adoption process Support from friends and family Baby shower The birth parents choosing us to raise their child Friends and family providing meals Friends and family babysitting Friends and family sharing their experiences with adoption

67. How has your child affected your life? (mothers @ 27 months) Marital Relationship Other Children Satisfaction With Life

68. How has your child affected your life? (fathers @ 27 months) Marital Relationship Other Children Satisfaction With Life

69. IV. Implications for Prevention and Services Most challenging parenting issues Desired services Format of services

70. What months have been the most challenging to parent?

71. What do adoptive parents think are the “most challenging issues” as parents (1 st year of life)

72. What do adoptive parents think are the “most challenging issues” as parents (2nd year of life)

75. Desired Adoption-Specific Parenting Services  Talking to child about adoption (how/when)  Contact with birth parents (how much/how to manage)  Transracial and cultural issues (how to educate)  Blended families (how to discuss with your children)  Stigma/responding to others’ questions

76. Agency services families wished the agency had provided More/better education about the adoption process More/better support groups More parenting education More staff accessibility Support groups pre-placement More support for birth mothers

77. How often wanted some advice about parenting? Mothers Fathers

78. Top 3 areas where parenting information would be helpful (mothers @ 27 months) Disciplining Managing Toddler Emotions Temper Tantrums

79. Top 3 areas where parenting information would be helpful (fathers @ 27 months) Disciplining Managing Toddler Emotions Sleep Issues

80. Other areas where help information and services would be helpful (at least 1/3 of mothers said information would be ‘helpful’ or ‘very helpful’) Enhancing child’s strengths (46%) General child development (43%) Adoption issues (42%) Child compliance (40%) Child hitting, biting (39%) Child whining (38%) Child temperament (37%) How to play with child (34%)

81. How would you like to receive parenting resource information? Mothers Fathers

82. How often would you like services? Mothers Fathers

83. Summary Most adoptive parents, and especially mothers, would like more information about parenting Areas where information and services are most desired are: discipline and child behavior, general child development, strength building, and adoption Adoptive families would prefer these services be delivered as an as-needed or monthly basis Mailed information, information from a doctor or pediatrician, or parenting website are the most desirable formats 0-2 months, 10-12 months, 18 months, and 24-months are times when parents report the most challenges

84. So where do we go from here? What kinds of services and programs might be beneficial?

85. Key components of ‘evidence-based’ programs for infants, toddlers, and preschoolers Teach warm and sensitive (but firm and consistent) parenting Strength-building Prevention-based Work within the multiple contexts that families and children interact in (home, school, community) Include both a child and caregiver components Include parenting groups for social support Weekly service delivery Video-based feedback

86. What about adoptive families? No evidence-based programs have been evaluated specifically for adoptive families, although there are evidence-based programs for foster parents Unique needs of adoptive families may include: generally well-educated and invested in parenting uncertainties about child’s genetic background transracial and cultural issues blended families interface with birth parents talking to child about adoption/their background ??
