this study is a single-centre randomised controlled trial involving elderly individuals with mild cognitive impairment in turkey. the research protocol was approved by the local ethics committee prior to the study. all participants gave written informed consent. this study was designed according to the consort statement, which provides a standardised method for randomised controlled trial (rct) design. participants: for the study, 60 elderly individuals with a diagnosis of hbb were evaluated. fifty individuals who completed the assessment and met the inclusion/exclusion criteria were included in the study. a virtual reality intervention group (n=25) and a person-centred occupational therapy intervention group (n=25) were formed with the online randomisation application available at https://www.randomizer.org/ by randomly numbering from 1 to 50 with simple random sampling method. two participants from the person-centred occupational therapy intervention group were excluded from the study because they did not regularly participate in the intervention programme. the study was completed with 48 participants. data were analysed with statistical package for the social sciences (spss) version 28.0 statistical package programme. the conformity of the data to normal distribution was tested by shapiro-wilk test. independent intergroup t test was used to compare normally distributed variables in two independent groups, and mann whitney u test was used to compare non-normally distributed variables in two independent groups. as descriptive statistics, mean (±) and standard deviation (x ± sd) values were given for numerical variables and number (n) and percentage (%) values were given for categorical variables. multivariate analysis of variance (manova) was used to evaluate the effectiveness of the interventions. it was seen that the prerequisites before manova were met. manova is used to test whether groups formed according to one or more factors show a difference in terms of more than one dependent variable. manova is a powerful multivariate statistic used in experimental research. the use of manova is appropriate when there is a relationship between dependent variables. in this study, box and leveni tests, which are the test statistics produced by manova to evaluate the differences between groups, were used to analyse the differences between groups. in the statistical analyses, the significance level was accepted as .05.
