Whereas family stress has been found to impact the emotional and physical health of individuals, a multisystem perspective on stress and coping focuses on four areas of life (individual, work, couple, and family). The Multisystem Assessment of Stress and Health (MASH) model builds a biopsychosocial model that is multidimensional and is designed to bridge research, theory, and practice. The model builds on the earlier family theory and research focusing on stress, coping and adaptation with individuals, couples and families. The model is multidimensional and utilizes a multisystem perspective including four areas of life: personal, work, couple, and family.
