This study examines the environmental and psychosocial determinants of
depression in older adults. Based on Lawton's environmental docility thesis,
the question is posed: is the strong association between functional limitations
and depressive symptomatology affected when environmental conditions,
objective and subjective efficacy, and docile or proactive behaviour are taken
into account. Data were used from LASA (the Longitudinal Aging Study
Amsterdam), a national survey of the population between 55 and 85 years of
age, stratified by age and sex. Hierarchical regression analyses were performed
on the data of 2,981 respondents. Empirical support was found for the
extended Lawton model, including both environmental, efficacy and
behavioural factors. In particular, living in a more urbanised area, not being
able to perform heavy household tasks, having a low self-efficacy, not feeling
safe, receiving help from others and having few social contacts within the
neighbourhood, increase depressive symptoms in general but, in particular,
when combined with lower functional status. It is concluded that both being
able and feeling able to influence one's environment increases proactive
behaviour and decreases depressive symptomatology in older adults with low
functional status.
