Transcript of Marital Violence
James Mitchell, Morgan Rund, et al. (2013)
Students, Southern Methodist University Methods Discussion Marital Violence Introduction The Psychobiology of Children Exposed to Marital Violence Relates to Class Symptomatology Exposure to Marital Violence Physical Child Abuse Heart Rate Blood Pressure Salivary Coritsol PTSD Results PTSD PTSD Blah blah PTSD blah blah Participants Exposed to Marital Violence Clinical Comparison Group Defined as having a recent police substantiated incident of domestic violence. This group was recruited from a mental health center, and suffered symptoms of anxiety, depression, and disruptive behavior. Conflict Tactics Scale was used, which measured the frequency of severe acts of domestic violence. A Blood Pressure monitor cuff was used. Blood Pressure Results: No main effect for pre or post interview data. Saliva samples were taken to assess HPA dysregulation. Salivary Cortisol results: Higher cortisol levels found in both pre and post interview samples. The Parent-Child Conflict Tactics Scale, which measured the frequency of acts of child abuse was used. Heart rate monitor used. Pre and post interview heart rates were
higher. The Trauma Symptom Checklist for Children was used. Significantly higher scores on the trauma checklist was found. Procedure 1.) Maternal Interview (Child abuse)
2.) Pre-child interview data gathered
3.) Post-child interview data gathered
4.) Comparison group This experiment focused primarily on the psychological and physical characteristics of children that experienced marital violence. Children exposed to marital violence were compared to a control group, which were children that did not experience marital violence. Past research indicates a relationship between PTSD due to marital violence due to parasympathetic nervous system dysregulation. The two physiological responses monitored in this study are the sympathetic nervous system and HPA axis functioning. Research Methods
-This study is experimental, because the study measures the differences between an experimental group and a control group.
-Physiological responses were measured in HPA axis and sympathetic nervous system, measured through heart rate, salivary cortisol and blood pressure. Marital Conflict
-Research on marital conflict supports the results of this study that say that there are negative responses to marital violence. Internal Working Model
-Because the relationship between a child and their parents is one of the first relationships they experience, children create a schema of violent relationships in their minds. Conclusion:
•The study found a correlation between witnessing violence and potential physiological effects.
•Marital Violence has a correlation with increased heart rate, but not other signs of physiological arousal
•Reactivity is limited
•Increased physiological arousal can be a precursor to PTSD
•The demographics between the control families and the martially violent families
•Lack of information on non-PTSD symptoms and diagnoses for both groups of children
•Underlying symptoms might affect physiological arousal
•Age group of children tested
•Reporter bias on whether the children have or were currently experiencing abuse
•Further Examination of correlation between physiological arousal indicators and marital violence
•Looking at correlations between sympathetic nervous system and martial violence
“Real World” Practices:
•Community and other support groups along with standardized and focused treatment plans
•Parents should avoid exposing their children to marital violence by reducing martial stress Hypotheses:
-children exposed to marital violence have more trauma symptoms
-physiological symptoms would be different for children in this situation
-Heart rate and blood pressure will be higher
-When interviewed about domestic violence, they will have more HPA activity and physiological response. This Study
-Look at physiological reactions of children around domestic violence.
-Sample: community sample of children exposed to domestic violence Children exposed to marital violence Children recruited from a children's mental health facility
