Purpose and or problem	Does genetics and biopsychosocial problems cause patients with Bipolar disorder to display anxiety?	Does abnormal metabolism in the brain in Bipolar patients limited to one particular area?
Relevance to Nursing	It is important for nurses to learn what triggers anxiety in patients, in order to assess and implement interventions.	This is important for nurses to understand the disease process that will facilitate teaching to patient and family members.
Setting	Other Country: Central Valley of Costa Rico	Choose an item. Country: Iowa
Sample	Size : 619 Type: 61 extended families and 51 unrelated healthy controls. Randomized? Yes ☐ No ☒	Size : 30 Type: 15 with DSM-IV diagnosis of bipolar 1 and 25 normal controlled group with no known psychiatric history Randomized? Yes ☐ No ☒
Hypothesis	Easy to find? Yes ☒ No ☐ What is it? Subclinical anxiety as a heritable trait genetically correlates wit.h Bipolar Disorder 1	Easy to find? Yes ☒ No ☐ What is it? T1p would be elevated in bipolar 1 disorder.
Independent variable (s)	Anxiety traits	T1 mapping
Dependent variable	Measurement of anxiety experienced over a lifetime	Brain Abnormalities
How is dependent variable measured? (Tools and/or Validity)	By using clinical information obtained from the Dagnostic interview for genetic Studies and using the STAI. The STAI is a self-rated instrument that measures anxiety	Variable measured using a 3 T siemens Tim Trio MRI system

Findings (Results)	The research was a limited success. The researcher was unable to find significant difference in score of BP1 mood status.	Lithium having a normalized effect on the brain that helps to control BP.
Important to you in your practice?	Yes ☒ No ☐ Explain: The research is important aid in the understanding of BD and why patients with bipolar, react the way they do.	Yes ☒ No ☐ Explain: It helps nurses to understand how someone with bipolar brain works, leading to new evidence based practices.
