A questionnaire formincluding personal descriptive information and patient s knowledge about the disease, Activities of Daily Living Scale (ADLs) and InstrumentalActivities of Daily Living Scale (IADLs) were used as data collection tools. Data were statistically analyzed with descriptive statistics (numbers,means, standard deviation, median, percentages), Kolmogorov-Smirnov Test, Shapiro-Wilk Test, Kruskal-Wallis Variance Analysis, Mann-Whitney U Test, Cronbach s Alpha Coeffcient and Spearman s Correlation Analysis.Results: 95.0% and 71.0% of the individuals told that they were independent while performing ADLs and IADLs, respectively. It was foundthat individuals who were female, at 77-89 years old, single, illiterate, housewife, had a low income level, had the disease for more than 15years, had joint deformity and with an accompanying disease with OA or had an idea that OA affected ADLs had lower ADLs score thanother groups (p<0.05). Individuals who were single, at 77-89 years old, illiterate, had joint deformity or who defned that OA affected ADLsand who received help while performing ADLs had lower ADLs score than other groups (p<0.05).Conclusions: It was concluded that individuals with OA should be helped, they should be supported in OA adaptation and the negativeeffects of the disease should be controlled.
