Each patient enrolled in the study is placed in one of these four groups. Then, using the randomized random list for each stratum (4 predefined lists), that person is in the intervention group A or control B. To create the desired list of 6 possible blocks, we assign quadrants to each numerical block (from I to VI): According to the random numbers table, numbers 1 through 6 correspond to the above blocks and do not count numbers 7 to 9 and 0. Random numbers are generated with Excel. Then the assignment list (from left to right) is determined for each stratum. N/A Gastric endoscopy. Intervention 1: Intervention group: َAt first,the demographic information questionnaire was completed and then anxiety measured by a six-item Spielberger inventory by the subjects and their physiological parameters (blood pressure and pulse rate) were measured and recorded in a sitting position with the same digital device. Then audio - video clip of nature music including sea, birds and forest sound was played for 5 minutes via tablet connected to headphones and immediately afterwards, Spielberger anxiety questionnaire and their physiological parameters (blood pressure and pulse rate) will be measured and recorded in sitting position. Intervention 2: Control group:At first,the demographic information questionnaire was completed and then anxiety measured by a six-item Spielberger inventory by the subjects and their physiological parameters (blood pressure and pulse rate) were measured and recorded in a sitting position with the same digital device. Then control group receive routine care in a sitting position equivalent to intervention time in intervention group and immediately afterwards, Spielberger anxiety questionnaire and their physiological parameters (blood pressure and pulse rate) will be measured and recorded in sitting position.
