Primary Outcome Measures

Name	Time	Method
Eating Disorder Screening	1 Day	A validated SCOFF questionnaire will be self-administered to patients attending their first preoperative bariatric surgery appointment. The SCOFF questionnaire is a simple 5-question test developed to assess the possible presence of an eating disorder. The S in SCOFF stands for "sick" (to vomit). The O stands for "one stone" of weight (i.e., 6.35 kg). The letters C, F and F stand for "control", "fat" and "food" respectively. Although the SCOFF is not used for diagnostic purposes, a score of 2 or more positive answers raises the index of suspicion of eating disorders, highlighting the need for a more detailed psychological history .The SCOFF has been previously validated in Arab populations.

Secondary Outcome Measures

Name	Time	Method
Depression	1 Day	Beck Inventory; Psychological screening and assessment for anxiety and depression will be carried by a clinical psychologist using a validated questionnaire. The Beck Depression inventory which includes a 21-item multiple choice self-report inventory will be used to measure depressive symptoms within the last week. Each question includes a set of 4 possible choices of how a participant may feel. Choices are scored from 0 to 3, increasing in intensity. The cut-offs to indicate depression include 0 - 9 minimal depression, 10 - 18 mild depression, 19 - 29 moderate depression, 30 - 63 severe depression.
Anxiety	1 Day	Kuwait University Anxiety Scale (KUAS); The Kuwait University Anxiety Scale will be used to measure level of anxiety. The 20-item scale will capture cognitive/affective anxiety (9 items), subjective anxiety or nervousness (7 items), and somatic anxiety (4 items) \[4\]. Responses use a 4-point Likert scale ranging from 1=rare, 2=sometimes, 3= often, 4= always to measure the level of anxiety . The cut offs to indicate anxiety include 0 - 21 normal, 22 - 42 mild anxiety, 42 - 63 moderate anxiety, 64 - 84 severe anxiety.
Obesity	1 Day	Height and weight will be measured using standard protocols by a qualified nurse during the patient's preoperative and post-operative appointments. Body Mass Index (BMI) will be calculated using WHO cut-off points to define obesity. Obese patients will be divided into different classes of obesity as the following: obese class I (BMI 30 - 34.9 kg/m2), obese class II (35 - 39.9 kg/m2) and obese class III (BMI \> 40 kg/m2).
