Research focus: Interparental Discord and Child Development
Background: What do we know? Child Development Interparental Conflict Associations between Interparental Conflict and Child Adjustment across Developmental Domains (Buehler et.al., 1997; Grych & Fincham, 2001)
What don’t we know? ? Child Development Interparental Conflict
Theoretical Perspective HPA axis Activity Child Development Interparental Conflict
HPA - Axis: Hypothalamus, Pituitary, Adrenal Marker of HPA axis activity: Cortisol
Cortisol is present in Saliva
Why do we care about cortisol? HPA axis is sensitive to social stressors and supports IPC is stressor Affects a wide variety of physiological systems Implications for short-term functioning and long-term outcomes Measurable non-invasively and reliably in naturalistic settings
Time Cortisol Time Organization of the HPA-Axis: Circadian Release of Cortisol
HPA activity in response to stressor
Time Cortisol Time Organization of the HPA-Axis: Momentary Reactivity to Stressor
Time Cortisol Time Frequent/Chronic Activation: Dysregulation
Time Cortisol Time Wake-up, Bedtime - Slope - AUC Individual Differences in Basal Functioning -CRT -CRTA

Study 1 Results: Do children living in homes with better marital functioning have lower average levels of cortisol than children living in homes with worse marital functioning? Yes!

Child Development Physiological Stress-Activity Interparental Conflict Negative Emotionality Current Study: Family Life and Stress Study
Participants and Procedures 2-parent families Child between 3-7 years In-Home by parents Part I: Surveys from both parents 8 samples of child saliva Part II, months later: Surveys from both parents 8 samples of child saliva 75$ for Part, 75$ for Part II Part III Labvisit
Method: Salivary Cortisol Sampling LickDipTasteSwoosh Spit in vial or cupClose …. Tightly!
Great job … YOU get a sticker!
Sampling times 2 consecutive weekdays 8 samples in the home Sampling times: Wake-up 30 minutes after 3.30 afternoon Bedtime
Measures Conflict Tactics Scale (CTS-2; Straus & Hamby, 1996) Negotiation Psychological aggression Dyadic Adjustment Scale (DAS; Spanier, 1976) Parental Involvement Depressive Symptomatology in last 2 weeks (IDD) Child Behavior (CBCL) and Social Competence Child Temperament Questionnaire (CBQ) Negative Emotionality (e.g., anger frustration, sadness)
Family Life and Stress Study: Research Question Do children living in higher conflict homes have higher average levels of cortisol production than children living in lower conflict homes, and is this association moderated by children’s levels of negative emotionality?
