Progressive Relaxation Exercises

The students who formed the control group and accepted to participate in the study will be asked to fill out the "Descriptive Characteristics Form", "Pittsburgh Sleep Quality Index (PSQI)", "Adult Resilience Scale", and "SF-36 Quality of Life Scale" in the first meeting. After filling out the data collection tools in the first meeting in the classroom, no intervention will be made. At the end of the 4th week follow-up period, separate data collection forms and post-test results will be obtained. The control group will be given a progressive relaxation exercise audio recording and booklets with written instructions stated in the audio recording.

Pittsburgh Sleep Quality Index: This scale is a 19-item self-report scale that evaluates sleep quality and disturbances in the past month. The PSQI consists of 24 questions, 19 of which are answered by the participant, while 5 questions are answered by the spouse or roommate. The scale is divided into 7 main components: Subjective Sleep Quality, Sleep Latency, Sleep Duration, Sleep Efficiency, Sleep Disturbances, Sleep Medication Use, and Daytime Dysfunction. Each component is scored between 0 and 3, and these scores give a total result between 0 and 21. A total score above 5 indicates poor sleep quality.

The scale containing a total of 33 items is in 5-point Likert type. The scale consists of 6 sub-dimensions. Of these, 'structural style' (3, 9, 15, 21) and 'perception of future' (2, 8, 14, 20) are measured with 4 items each; 'family harmony' (5, 11, 17, 23, 26, 32), 'self-perception' (1, 7, 13, 19, 28, 31) and 'social competence' (4, 10, 16, 22, 25, 29) are measured with 6 items each and 'social resources' (6, 12, 18, 24, 27, 30, 33) are measured with 7 items. In the scale, positive and negative features are on separate sides in order not to cause biased evaluation. Five separate boxes were created for the answers. The scoring method was left free in evaluating the level of psychological resilience as low or high. The validity and reliability Cronbach alpha coefficient of the scale was determined as 0.86 (1) by Basım and Çetin (2011), and 0.89 in this study. Considering that psychological resilience increases as the scores increase, the scoring is done as 1-2-3-4-5 from left to right

SF-36 Quality of Life Scale: The scale consists of 36 items and these provide the assessment of different health dimensions under 8 subscales: 1) Physical function (10 items) 2) Social function (2 items) 3) Role limitations due to physical problems (4 items) 4) Role limitations due to emotional problems (3 items) 5) Mental health (5 items) 6) Energy/vitality (4 items) 7) Pain (2 items) 8) General health perception (5 items) (Ware & Sherbourne, 1992). The scale is assessed by considering the last 4 weeks. A form evaluating the last 1 week was also applied in order to create the acute form. The assessment is made in Likert type (three-point-six-point) except for items 4 and 5; items 4 and 13 and 5 are answered in a yes/no format. Instead of giving a single total score, the scale gives a total score for each subscale separately. The second question of the scale, 'Compared to last year, how do you evaluate your health now?' only includes one-year changes, but this question is not included
