title: Restriction in instrumental activities of daily living in older persons: association with preferences for routines and psychological vulnerability.
abstract: Disabilities in the Instrumental Activities of Daily Living (IADL) are frequently observed in older adults. A restriction in the daily life activities in the elderly may be related to a process of routinization induced by homogenization of activities, in addition to its association with emotional states. The relationship between level of functional disability for IADLs and preferences for routines was explored in 207 non-demented French participants (Mage = 84.2 years, age range: 78-96 years) from the PAQUID cohort study. Multinomial regressions analyses showed that preferences for routines were significantly associated with a higher risk of restriction for at least two functional activities, after adjusting for sociodemographic and psychological variables. However, this association was non significant after controlling for cognitive variables. These findings add new elements for understanding the effect of routinization in the disability process in older persons in that preferences for routines could constitute a risk factor of IADL restriction, similar to cognitive decline.
