When establishing the care needs of older adults following disastrous or critical events, practitioners need an assessment and intervention plan. Usually this plan involves integrating several models of care, in this case, the functional-age model of intergenerational therapy (F AM) and the resilience-enhancing model (REM). Both models share several assumptions including the need to address the biopsychosocial and spiritual functioning of the individual, the significance of examining the family as a developmental system, and the importance of involving ecological systems in care planning.
