Aim of the Study: The aim of this study is to find the perception of difficulty and dependency (PDD) of elderly people in bathroom use in relation to age and disability type. Perception of difficulty-dependence (PPD) corresponds to the personal level of perception when doing an activity without taking any support or the amount of support to be needed. Aging and Impairment: Aging is a process that restricts the human activities through appearing physical disabilities in time. Impairments that accompany the aging are resulted by the lost or decreased body functions. Studies in ergonomics and gerontechnology try to improve the relationship between the physical environment and the elderly people. Because of the increasing number of elderly people and life expectancy, there is an interest to search and rehabilate the conditions in their own living environments of the elderly people. Beyond being a physical shelter, house is a private living environment that elderly people spend majority of their time while finding personal security and privacy there. Bathroom is one of the major places of a house where people always seek for privacy and independency. Method of Inquiry: A questionnaire was distributed to 63 elderly people aged between 50 to 80. The results of this research represented the findings about aging and impairments, which are accepted as part of being elderly, in relation to bathroom activities. Since getting older and accompanying impairments are accepted as the determinants of the aging process, these two factors which were investigated for their influence on perception of difficulty-dependence in bathroom activities of elderly people formed the main hypotheses of the research. Findings and Conclusions: Though the perception of difficulty-dependence (PDD) in bathroom tasks is generally low in the participants aged between 50-60, the distribution in PDD is getting wider in the participants aged between 70-80 (e.g. p=0.002 for fixing shower head). A sharp increase was found in PDD in the ages above 80 (e.g. p=0.002 for entering bath-tube). It was also found that PD is getting higher depending on the number and variety of the disabilities. Visual disability is found to be prevalent to all ages but not to be influential as much as the others on PDD in bathroom tasks. Because of the privacy expectation in the bathroom, all ages and disability types refrain receiving help when having the bath. Further Study: The study will be developed by increasing the sample size. Depending on the increased sample size, it is possible to question the influence of specialized bathroom details such as grasping bars for the accessibility. Measurements and style differences of the bathroom equipment on PDD are other issues of research with the increased sample size. In bathrooms, various sources of accessibility problems can cause serious health problems and threatens subjective well-being of the elderly people.
