The Mind-Body Study: study design and reproducibility and interrelationships of psychosocial factors in the Nurses' Health Study II.

ABSTRACT:

Purpose

Associations between psychosocial factors and biomarkers are increasingly investigated in studies of cancer incidence and mortality. Documenting optimal data/biospecimen collection protocols and scale properties are fundamental for elucidating the impact of psychosocial factors on biologic systems and ultimately cancer development/progression.

Methods

Between 2013 and 2014, 233 Nurses' Health Study II women (mean age: 60.6) participated in the Mind-Body Study. Participants completed a detailed online psychosocial assessment and provided hair, toenail, timed saliva over 1 day, urine and fasting blood twice, 1 year apart. Additionally, two separate microbiome collections for stool and saliva were conducted between the psychosocial assessments. We assessed correlations
