The ISI is a scale composed of 7 questions:

Each of the 7 items is rated on a 5-point Likert scale (from 0 to 4). The total score is obtained by adding the scores for all 7 items (1a+1b+1c+2+3+4+5). The total score ranges from 0 to 28:

0-7 = No insomnia 8-14 = Subclinical (mild) insomnia 15-21 = Clinical (moderate) insomnia 22-28 = Clinical (severe) insomnia

Depression Scale Score (PHQ 9)

• Items are rated on a scale from 0 to 3. The maximum score is 27.
• The threshold for assessing moderate depression (10 or higher) is the most commonly used. • Thresholds:

No depression: 0-4 points; Mild depression: 5-9 points; Moderate depression: 10-14 points; Moderately severe depression: 15-19 points; Severe depression: 20-27 points.

Anxiety score (GAD-7):

The total score of the GAD-7 questionnaire ranges from 0 to 21 points. Scores of 5, 10, and 15 represent thresholds for detecting mild, moderate, or severe anxiety:

Score 0-4: Minimal anxiety Score 5-9: Mild anxiety Score 10-14: Moderate anxiety Score above 15: Severe anxiety

Posttraumatic Stress Disorder Score (PCL-5):

The PCL-5 scale assesses the presence and severity of PTSD using 20 items.

The PTSD severity score ranges from 0 (not present at all) to 4 (extremely), resulting in a total score between 0 and 80. PCL-5 scores were used to determine the presence of PTSD.:

A score:

above 33 indicates the presence of PTSD, between 31 and 33 indicates probable PTSD below 31 indicates no PTSD.

Addictions Score (DAST-10):

The maximum total score is 10. A threshold of 3 or 4 is recommended for screening for a drug use problem. This threshold would most closely match the criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM):

A score of 9 or higher indicates a severe problem.
