For this purpose, four-membered blocks consisting of all four possible combinations were defined as having two A members (intervention group) and two B members (control group), and at the time of randomization, a block was randomly selected and the samples assigned to the intervention or control group based on the results. The six possible four combinations are: AABB, ABAB, ABBA, BAAB, BABA, BBAA One envelope was provided for each block, containing four cards, two cards marked A and two cards B. The order of the cards in each envelope was in accordance with one of the above patterns and we had a total of six envelopes (numbered from one to six). At the time of random allocation, one of the envelopes was randomly selected, and as a result, four patients entered the study and their assignment was identified. when the envelope was identified, all four cards were not pulled out together, but with each patient, one card (in the envelope, respectively) was removed and discarded. After inserting four samples into two groups, the cards were placed in the same order at the envelope, and the envelope was returned to its original location. N/A Alzheimer's disease. Intervention 1: Intervention group: In this study, educational intervention with spaced retrieval - errorless method was used. The target information provided to the elderly at the beginning of each session consisted of 16 images, of which 8 were images of painful situations, 5 were images of non-painful situations, and 3 were unrelated. These images were randomly selected from 128 images validated in previous studies. All images were related to familiar daily activities, and the photograph was taken in such a way that the situation was recognizable at first glance. Different types of mechanical, thermal and pressure pain have been depicted and these images are of different age and gender. These images have been used in similar studies to assess pain semantic memory. The elderly were asked to remember the target information. Then, at 45, 90, 180, 360, 720 seconds intervals, the elderly were asked to identify images of painful situations. The retrieval time was increased, if of the responses were correct. Every time the elderly failed to identify the images correctly, the time interval was reduced to a previous step, and the painful images were trained again. The images presented at each session were different from the previous session, and at the end, the elderly participants were introduced to 64 painful situations. Activities that do not require much memory function such as solving puzzles were used during data retrieval. Intervention 2: Control group: Eight free group discussion sessions were held twice a week.Meetings were held with easy, comprehensible, and interesting topics. The sessions lasted up to one hour.
