• The Dutch Eating Behavior Questionnaire [ Time Frame: Baseline in experimental and control groups. ]
  It was designed to measure eating styles that may attenuate or contribute to the development of overweight. It comprises three scales that measure emotional, external and restrained eating. The Spanish version of the DEBQ has 33 items, 13 of them referred to the emotional eating scale (e.g., "Desire to eat when irritated"), and 10 items referring to the external (e.g., "Eating when you feel lonely") and restrictive (e.g., "Difficult to resist delicious food") scales, respectively. The items can be rated on a five-point likert scale with 1 indicating "never" and 5 indicating "very often".

The participants indicate on a 5-point Likert scale the degree in which each item is generally true for them, ranging from 1 ("never or very rarely true") to 5 ("very often or always true").

Items are rated on a 4-point Likert-type scale (between 0 = "not at all" and 3 = "nearly every day"). The GAD-7 inquires about events happening over the last two weeks, in order to know how often the patient has been bothered by them

  Mindful Eating program is apply face to face 7 sessions of 120 minutes/session. ME is apply in groups of 10-12 people in traditional format. Written material and sound recordings will be offered as support elements. The estimated duration of the face to face program is two months.

  Treatment As Usual (TAU) in Primary Care (PC) is any kind of treatment administered by the GP to the patient with overweight and obesity. According to nutritional status, overweight or obesity, as well as the presence of co-morbidity, different actions can comprise the treatment offered at a PC level. For individuals presenting with overweight (BMI 25-29.9 kg/m2) but with no co-morbidities, PC teams organise care plans to enable them to achieve a normal BMI range (BMI 18.5-24.9 kg/m2). In case of suicide risk, severe social dysfunction or worsening of symptoms, it is recommended that patients are referred to mental health facilities.
