Objective: In this study, it was aimed to use the Turkish version of the Kitchen Picture Test (KPT), which was developed to evaluate judgment skills, to compare judgment skills in patients with dementia due to Alzheimer's Disease (AD-Major Neurocognitive Disorder) with healthy elderly people.

Material and Method: The sample consisted of 55 older people, 30 of whom were diagnosed with major neuropsychiatric disorder due to AD according to the DSM-5 diagnostic criteria, and 25 healthy volunteers. Montreal Cognitive Assessment Tool (MoCA), Mini Mental State Examination (MMSE), Clock Drawing Test (CDT), Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) and Verbal Auditory Learning Test to assess general cognitive functions, Functional Activities Questionnaire (FAQ) to assess daily functioning, Similarities, Comprehension and Digit Span subscales of Wechsler Adult Intelligence Scale-Revised Form (WAIS-R) to assess working memory and abstraction skills, KPT to evaluate the judgement and the Hamilton Depression Rating Scale-17-item (HDRS-

17) form for depression symptoms were applied. The socio-demographic characteristics and scale scores were compared using the independent sample t-test or Mann-Whitney U test.

Results: AD group was older and education levels were lower. There was no difference between two groups in terms of gender. Clinical subscales of two groups were significantly different between total mean scores. Judgment and total scores of KPT on AD patients were lower. Judgement and total score of KPT showed positive and significant correlation with MMSE total, MoCA total, WAIS-R subscales scores. Cronbach Alpha Reliability Coefficient was determined as α = 0,79, and it was shown that MRT Turkish form was reliable.

Conclusion: According to the results of this study, the Turkish form of MRT is a valid and reliable tool that can be used to evaluate judgment skills in patients with AD.
