Plain English summary of protocol
Background and study aims:
Extreme weight conditions can be resistant to treatment in some cases, especially when linked to eating disorders. The first aim of this study is to assess the brain activity, impulsivity and emotional stimuli response of patients with abnormal eating and situations of altered weight (i.e.: underweight with anorexia (AN) or overweight/obesity with bulimia nervosa (BN) or binge eating disorder (BED)) compared to healthy women. The second aim is to evaluate the short-term effectiveness of Playmancer, a therapeutic videogame designed to improve emotion regulation and impulsivity control.
Who can participate?
Women aged 18-60 referred to the Eating Disorder Unit of the Bellvitge University Hospital (AN-underweight or BN/BED-overweight), and women of the same age range with no mental health conditions
What does the study involve?
All participants are assessed at the start of the study with a psychological and neuropsychological tests and an electroencephalogram (EEG) (a recording of brain activity). After the assessment patients are randomly allocated to either treatment as usual (Cognitive Behavioral Therapy [CBT]) or treatment as usual and Playmancer. Patients with AN receive 12 weeks of CBT treatment while in day care; patients with BN/BED and obesity or overweight receive 16 weekly session of CBT treatment in outpatient premises. The Playmancer intervention consists of nine 20-minute sessions over 3 weeks (3 sessions per week). Changes in neuronal activity and functioning are evaluated at 4 weeks and at the end of treatment.
What are the possible benefits and risks of participating?
Although the neural changes associated with Playmancer treatment have not yet been studied, the effectiveness of Playmancer has been proved in different populations and it is associated with improved emotion regulation and decreased impulsivity. Patients may benefit from receiving Playmancer treatment and if they do not receive Playmancer they still receive treatment as usual. There are no risks associated with the study.
Where is the study run from?
1. Bellvitge University Hospital (Spain)

| Scientific title | Neurocognition and emotional regulation in extreme weight conditions: study of brain activity and cognitive changes associated with an intervention based on a therapeutic videogame |
| Study objectives | This study aims to test if two extreme weight conditions groups (i.e.: Anorexia Nervosa-underweight and Bulimia Nervosa/Binge Eating Disorder-overweight/obesity) present some shared processes of brain activity and neuropsychological-clinical functioning underlying impulsivity and emotion regulation which differ from the ones observed in healthy controls. It also aims to assess if the two clinical groups are differentiated by specific patterns underlying impulsivity and emotion regulation. Finally, it tests if the therapeutic videogame (Playmancer) efficiently enhance emotion regulation and impulsivity control when measured through neurophysisiological (EEG) and cognitive functioning techniques. |
| Ethics approval(s) | University Bellvitge Hospital Research Ethics Committee, 21/01/2016, ref: PR146/14 |
| Health condition(s) or problem(s) studied | Eating disorders and extreme weight conditions (i.e.: underweight- Anorexia (AN), overweight/obesity-Bulimia Nervosa (BN)/Binge Eating Disorder (BED) |
| Intervention | Participants are randomly allocated to two different interventions: 1. Treatment as usual (TAU, which is Cognitive Behavioral Therapy [CBT]) 2. TAU + Playmancer (a therapeutic videogame to improve emotional regulation through biofeedback techniques) The TAU is part of daily clinical practice and is a protocolized CBT intervention which has been proven to be effective for eating disorders. Patients with Anorexia Nervosa receive 12 weeks of CBT treatment while in day care; patients with Bulimia Nervosa (BN)/Binge Eating Disorder (BED) and obesity or overweight receive 16 weekly session of CBT treatment in outpatient premises. The Playmancer intervention consists of nine 20-minute sessions which are implemented during 3 weeks (3 sessions per week). At a baseline level, a healthy control group (HC) is recruited which is matched in age and education level with the participants of the intervention groups. |
| Intervention type | Behavioural |
| Primary outcome measure | Primary outcome measures at baseline (cross-sectional study): differences between the three groups: AN-underweight, BN/BED-overweight/obesity, healthy controls (HC) Primary outcome measures for the intervention (randomized clinical trial): differences in changes between the two intervention groups in two different extreme weight conditions. The two clinical groups are assessed at three different timepoints: 1) baseline before starting treatment (pre), 2) after 4 weeks of treatment coinciding with the end of the Playmancer intervention (Post 1) and 3) at the end of treatment (Post 2). The HC is only part of the baseline assessment. Assessment battery: 1. Emotion regulation and impulsivity measures (Pre-Post 1- Post 2): UPPS -P Conducta Impulsiva Scale (Whiteside y Lynam , 2001), Escala de dificultades en la Regulación Emocional Escala (Ders; Gratz y Roemer , 2004), Cuestionario de Regulación Emocional (ERQ; Gross & John, 2003), Yale Food Addiction Scale (YFAS; Gearhardt et al., 2009) 2. Neuropsychological measures. Pre-Post 1-Post 2: Stroop Colours and Words Test (SCWT; Stroop, 1935; Golden, 1978), Iowa Gambling Task (IGT): (IGT; Bechara et al., 1994), Continuous Performance Test-II (CPT-II; Conners & Staff, 2000). Pre: Subtest de Vocabulario de la Wechsler Adult Intelligence Scale-III (WAIS-III) 3. Neurophysiological measures (EEG) (Pre-Post 1-Post 2). Three paradigms: emotion regulation task, craving regulation task, emotion go no go task. Event-related potentials will be analyzed for the different paradigms |
| Secondary outcome measures | 1. Clinical measures (Pre, Post 1, Post 2): Symptom CheckList-90 items-Revised (SCL-90-R; Derogatis et al., 1977), Eating Disorders Inventory- 2 (EDI-2; Garner, 1991), Screening diagnóstico SCID-I para trastornos mentales del Eje I (First, 1996) 2. Personality scale (Pre): Temperament and Character Inventory-Revised (TCI-R; Cloninger, 1999) 3. Weight, height and Body Mass Index (Pre, Post 1, Post 2): TANITA MC-180 Multifrecuencia.(TANITA 8, Bioimpedancia) |
