Brief Summary

Participants 60 Patients seeking treatment at the Obesity Unit of the Medica Sur Hospital in México City, Mexico. Informed consent to participate will be aleatory assigned to a three different conditions. Procedures In the initial interview, prospective participants will be provided with detailed information about the study and the treatments. All patients included in the study will be randomly assigned to the one (N=20) of the three treatment conditions described below, all conducted on an inpatient basis. The duration for all treatments will be 6 weeks and will be administered by two chartered clinical psychologists and one chartered psychotherapist under the supervision of a senior chartered psychotherapist. The three therapists will be balanced among the three conditions.

  1. 1.Nutritional groups In this condition (NT) the participants (N=20) subjects enter only 5 weekly nutritional groups held by dieticians based on the LEARN manual (Brownell, 1985), whose goal will be to provide practical guidelines for the self-monitoring of eating and lessons on nutrition (e.g stressing gradual weight loss with the caloric restriction achieved largely by reductions in fat intake), plus a low-calorie diet (1,200 kcal/day) and physical training (30 min of walking two times a week as a minimum).
  2. 2.Cognitive-Behavioral therapy CBT group (N=20) will be based on the same treatment proposed in the first condition plus 15 additional sessions over 6 weeks.
  3. 3.Experiential Cognitive therapy Experiential CT group (N=4) involved the same treatment proposed in the first condition plus 15 additional sessions over 4/6 weeks.

Outcome Measures

Primary Outcomes (3)

  • Anxiety Inventory: State-Trait IDARE

    The scale A-Trait Anxiety Inventory consists of twenty statements in which subjects are asked to describe how they feel generally. A-State scale also consists of 20 statements, but the instructions required that subjects indicate how they feel at any given time. Measures two dimensions of anxiety: state (referring to how the subject feels at that moment) and trait (how you feel usually). Instrument validated in Mexico (Spielberger \& Diaz Guerrero, 1975)

  • Body Image Questionnaire (BSQ)

    Designed by Cooper, Taylor, Cooper and Fairburn (1987), adapted to Spanish population by Raich et al. (1996) and to Mexican women by Galán (2004). Consists of 34 questions scored on a Likert scale of 1 to 6. Lets get an overall score (sum of raw scores of the items) and can be derived 4 subscales: body dissatisfaction, fear of gaining weight, low esteem by the appearance and want to lose weight.

Interventions

Is a relatively short-term, integrated, patient oriented approach that focuses on individual discovery (Riva, Bacchetta, Baruffi, Rinaldi, \& Molinari, 1998, 1999; Riva et al., 2000). It shares with the cognitive-behavioral approach proposed by Cooper and colleagues the use of a combination of cognitive and behavioral procedures to help the patient identify and change the maintaining mechanisms (Cooper et al., 2003). However, it considers morbid obesity as a peculiar form of addiction. So, as in the cognitive-behavioral treatment of addictions (Carroll et al., 1994) the two main goals are the functional analysis of the maintaining mechanisms and the required skill training (relapse prevention).

ECT

Therapists will follow a detailed manual that outlined the content of each session. This manual was based on the cognitive-behavioral treatment approach described by Cooper and colleagues (Cooper \& Fairburn, 2002; Cooper et al., 2003). It was developed during a year of intensive pilot work and adapted to the in-patient setting. Patients will be taught to self-monitor their food intake and eating patterns and thoughts, as well as the circumstances and environment surrounding eating (e.g. whether eating alone or with others, speed of eating, and place of eating). Patients will also be taught to identify problems in eating, mood, and thinking patterns and to gradually develop alternative patterns.
