Katz 50 Disability Basic activities Difficulty in activities of daily living (e. Modification and extension of the Verbrugge and Jette model of disablement. Modifications are: (1) combining impairment and functional limitations into a ‘health status’ category, (2) differentiation of types of disability (basic and advanced), and (3) suggestion that difficulty in basic activities will be associated with greater loss (relinquishment) of advanced activities. The model is extended to encompass the effects of disability on psychological well-being. What Are the Implications of the Relationship between Function and Psychological Well-Being for the Model of Disability? Based on the findings just described, a modification and extension of the Verbrugge and Jette model of disablement that encompasses the effects of disability on psychological well-being was developed (fig. In this model, decrements in health status, which includes both pathology (e. Disability is defined as difficulty in activities, inability to perform activities, or relinquishment of activities. Disability may be experienced in basic areas of function (roughly comparable to Verbrugge’s categories of obligatory and committed activities) or in advanced activities Disability and Psychological Well-Being 51 (roughly comparable to Verbrugge’s discretionary activities). Difficulty in basic activities is also likely to lead to relinquishment of advanced activities, due to increased time and energy requirements needed for basic activities. This aspect of the model has not yet been tested, however, although previous research suggesting a hierarchical development of disability supports the hypothesis [48, 50]. Although disability in basic activities may be associated with psycho- logical distress, in general, research shows that it is disability in these more advanced activities that is associated with the onset of psychological distress [47, 49, 50]. The relationship was stronger among younger individuals than among older. In a study of older adults, those who stopped driving, which could potentially reduce their access to paid and volunteer work, community services and businesses, friends, and religious activities, were at increased risk of worsening depressive symptoms.
