Patients' medical charts in the outpatient clinic were reviewed to identify those who meet the inclusion criteria. Patients who meet the predetermined inclusion criteria were recruited in the study using simple randomization technique using computer-generated sequence technique to pick up these patients. After simple sampling and dividing patients into two groups of study and control. Patients from the study and control groups were interviewed individually by the researcher to apply the study tools

The program of intervention took four-weeks for each patient (total eight sessions- four outpatient sessions and four home-based sessions- two sessions per week- one outpatient and one home session/week). The outpatient sessions were done once per week during the patient visit to the outpatient clinic, as the patients visited the clinic 4 times/ month.

Patients in this control group will be left without any intervention to undergo the usual outpatient routine care.

Aromatherapy is safe, well prepared mixture used in the study that prepared by professor of pharmacology, faculty of pharmacy by mixing lavender essential oil and lavender hydrolate

After simple sampling and dividing patients into two groups of study and control. Patients from the study and control groups were interviewed individually by the researcher to apply the study tools as a pretest. Aromatherapy intervention was carried out for patients in the study group while those in the control group were left without any intervention to undergo the usual outpatient routine care.

The scale was developed by (Beck, 1979; Beck, Steer, & Brown, 1996a; Beck, Ward, Mendelson, Mock, & Erbaugh, 1961). It is a standardized self-report rating inventory that measures attitudes and symptoms of depression in normal and populations with psychiatric disorders. The BDI-II contains 21 items across two Affective and Somatic subscales. Each item is measured on a 4-point Likert scale from 0 (symptom absent) to 3 (severe symptoms). In addition, items of sleep and appetite were assessed over seven options to determine their hypo or hyperactivity level. The minimum score is 0, and the maximum score is 63, while higher scores indicate greater severity of depressive symptoms. The total score of 0-13 is considered the minimal range of depressive symptoms; 14-19 is mild; 20-28 is moderate, and 29-63 is severe.

The Beck Anxiety Inventory (BAI) was developed in 1988 and consists of 21 items with a Likert scale ranging from 0 to 3 and raw scores ranging from 0 to 63 (Beck, Epstein, Brown, & Steer, 1988). The questions used in this measure ask about common symptoms of anxiety that the subject has had during the past week (including the day you take it). The BAI contains 21 questions, each answer being scored on a scale value of 0 (not at all) to 3 (severely). Higher total scores indicate more severe anxiety symptoms. The scores are classified as low anxiety (0-21), moderate anxiety (22-35) and potentially concerning levels of anxiety for score of 36 and above
