In the sample selection stage, convenience sampling method will be used. After selecting a sample size of 30 people based on the research entry and exit criteria, participants will be randomly assigned to two groups: "Acceptance and Commitment Therapy" (intervention group) and "Waiting List" (control group). Randomization will be performed using the random block method with variable sizes (4 and 6 people) by an independent statistician who is not involved in the implementation process. The random allocation list will be generated using the RAND function in Excel software and then placed in opaque, sealed, and numbered envelopes so that the researcher and participants are not aware of the allocation sequence (allocation concealment). The envelope will be opened and the allocation group will be informed only when each participant enters the study. To ensure the equality of baseline variables (such as anxiety level, age), their distribution in the two groups will be examined during the statistical analysis stage. N/A Anxiety.
