Testing a Family System-based Intervention (ENTREN-F Programme) for a paediatric obesity sample by a Randomized Controlled Trial.

This study evaluated the effectiveness of 'ENTREN-F' -a multi-component, family system-based intervention- for managing paediatric obesity at National Health Primary Care. A 3-arm, parallel-design, single-blinded randomized controlled trial (RCT), 165 families were randomized: Arm 1) ENTREN-F(n = 62) is a 12-week cognitive-behavioural intervention (CBT) family system-based programme, addressing lifestyle changes, children's emotional and social development and the family system, Arm 2) 'ENTREN' (n = 52) is a CBT family-based programme for children and parents, not addressing the family system, and Arm 3) Control group (CG) (n = 51) covers individual behavioural monitoring. All children were clinical interviewed to assess a diagnosis. Their effectiveness was assessed against six-month changes in children's body mass index (BMI) z-score, children's psychological well-being, levels of expressed maternal emotion, depression symptoms, parental feeding practices, levels of physical activity and sedentary lifestyles. The maintenance of the changes was evaluated for two years. High-attendance rates for ENTREN-F (72.6% vs. 66% vs. 33%, respectively) indicated its greater acceptance. After programme completion, the BMI z-score reduced by 0.5 points in almost 50% ENTREN-F (n = 22/45), 21.9% ENTREN (n = 7/32) and 11.8% (n = 2/17) CG participants. There were no significant differences between the three trial arms for anthropometric, psychological, or family-related measures. At the two-year follow-up, both ENTREN-F and ENTREN showed similar long-term effectiveness without between-group differences, and weight trajectories were favourable. ENTREN-F appears effective for childhood obesity management; however, the COVID-19 pandemic limited the sample size. Also, the tendency towards multiple differences in child and family outcomes could not be statistically shown. It also provides further evidence of the role of psychological and family-related factors that may underlie the origin and maintenance of weight gain.

Childhood obesity and adolescent follow-up depressive symptoms: exploring a moderated mediation model of body esteem and gender.

Obesity is a well-recognized risk factor for adolescent depressive symptoms, but mediating mechanisms of this association have scarcely been studied. This study is unique in examining an indirect pathway of this link via body esteem (BE) prospectively from childhood (8-12 years) to adolescence (13-18 years). In addition, potential gender moderation was examined. This study utilized data from a case-control study comparing 100 children with and without obesity matched on important confounders (age, gender, and socioeconomic status). Our findings provide support for the mediating role of BE in the link between childhood weight status and adolescent depressive symptoms at a 5-year follow-up. This mediation effect did not differ between boys and girls. The findings suggest the relevance of specifically targeting children's BE in preventive intervention programs among children with obesity to prevent future mental health problems.

Family-reported barriers and predictors of short-term attendance in a multidisciplinary intervention for managing childhood obesity: A psycho-family-system based randomised controlled trial (ENTREN-F).

OBJECTIVE: This study was aimed to examine patient enrolment in the pre-intervention stage, family-reported barriers, attendance rates and underlying predictors of short-term attendance in a family-system-based randomised controlled trial for managing childhood obesity in children aged 8-12-years-old (ENTREN-F). METHOD: Psychosocial and anthropometric measures were collected through primary health referral. The data were used for descriptive analyses of sample characteristics and linear regression analyses. RESULTS: Low enrolment rates and several family-reported barriers were observed in the pre-intervention stage. Logistical barriers were the most frequent family-reported reason for attrition in the different stages of the study. Having a first face-to-face orientation session with the families and the use of motivational interviewing helped to improve adherence in the initial phases of the study. After 6 months of intervention, family based treatments (FBTs) under consideration achieve greater adherence compared with the standard intervention. Moreover, family involvement was a predictor of success for better treatment adherence rates. By contrast, participants who attended a brief standard intervention, mothers with primary education, greater body mass index, higher levels of depressive symptomatology and more critical comments towards their children, children with higher weight status and lower levels of self-reported depressive symptoms at baseline attended interventions less frequently. CONCLUSIONS: In future programmes a comprehensive screening of modifiable factors related to family and their setting characteristics is paramount prior to intervention, identifying key barriers related to drop-out, especially in the case of less-advantaged families.

Using structural equation modeling to understand family and psychological factors of childhood obesity: from socioeconomic disadvantage to loss of control eating.

PURPOSE: Current study aimed to empirically test the Hemmingsson's theoretical model of childhood obesity which emphasizing the importance of family environment and the emotional distress of parents as influential variables in the emotional distress of the child and subsequent weight gain. This study also tested the hypothesis that the emotional distress of the child triggers a weight gain-inducing behavior (loss of control eating) to suppress negative emotions. METHODS: Families of 220 Spanish children participated in the study (28.2% normal, 35.1% overweight and 32.2% obesity), aged between 8 and 12. The evaluation included a clinical interview and a battery of questionnaires. RESULTS: Structural equation models were computed according to the steps proposed by theoretical model. Fit indices were acceptable suggesting that the data adequately fit the hypothesized model. Path coefficients in the final model were statistically significant showing a relationship between socioeconomic status, the emotional distress of parents, family environment, the emotional distress of children, loss of control eating and child's BMI Z-score. CONCLUSION: Considering this relation between emotional distress and child weight status, childhood obesity intervention programs may benefit from targeting family environment and the potential role that food is playing in the regulation of children's distress. LEVEL OF EVIDENCE: Level III: Cohort analytic study.

Spanish validation of the Modified Weight Bias Internalization Scale (WBIS-M) for adolescents.

PURPOSE: Weight Bias Internalization (WBI) is pervasive and potentially damaging for health. Little is known about WBI in youth. As negative effects of WBI have been observed when controlling for BMI, measures that allow WBI to be assessed across different weight categories are needed. The Modified Weight Bias Internalization Scale (WBIS-M) is one of the most frequently used scales in this field. Our purpose was to obtain a Spanish validated version of the WBIS-M for adolescents across different weight statuses. METHODS: The data were collected from 298 secondary students (mean age 14.31; 48.32% girls; 18.8% were overweight and 6.4% had obesity). Internal structure was examined by a cross-validation analysis, using both exploratory and confirmatory factor analyses in different subsamples. RESULTS: Item 1 showed a psychometric anomalous functioning and was deleted. The one-factor structure of the 10-item version was confirmed with adequate fit ([EFA (KMO = 0.915, χ2(55) = 1075.633, p < 0.0001)]; [CFA (χ2(35) = 200.515; GFI = 0.995; PGFI = 0.992; NFI = 0.991; SRMR = 0.060)]). Internal consistency was high [Formula: see text] ω = 0.93). Significant correlations with the same set of external variables assessed in the original version (anti-fat bias, self-esteem, mood, body dissatisfaction, drive for thinness, binge eating), all of them correlates of WBI in adolescents, were found. Girls and participants with obesity obtained higher scores. CONCLUSION: The results provide support for the validity and reliability of our WBIS-M version for use with adolescents across weight categories in Spain. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort studies.

Biological, psychological and familial specific correlates in eating disorders at onset: a control-case study protocol (ANOBAS).

The complexity in the development of an eating disorder (ED) pose methodological challenges when addressing risk factors of this pathology. Pike et al. (2008) proposed to use a case-control design for this type of research.

Adding maintaining factors to developmental models of anorexia nervosa: An empirical examination in adolescents.

OBJECTIVE: A biopsychosocial approach has been proposed to explain the pathogenesis of anorexia nervosa (AN), despite only a few of the existing etiological models having received empirical support. The aim of this study was to empirically investigate Herpertz-Dahlmann, Seitz, and Konrad (2011, https://doi.org/10.1007/s00406-011-0246-y)'s developmental model and to consider if interpersonal reactions to the illness might serve as maintaining factors following the model proposed by Treasure and Schmidt (2013, https://doi.org/10.1186/2050-2974-1-13) METHOD: One hundred adolescents and their families were participated in the study: 50 diagnosed with AN, paired by age and parents' socio-economic status with 50 adolescents without a pathology. Biological, psychological and familial variables were assessed using ten questionnaires and a blood analysis test. Additionally, structural equation modeling was conducted to assess two hypothetical models. RESULTS: The fit of both models was good after the addition of two covariate parameters (e.g., Comparative Fit Index > 0.96 and Tucker-Lewis Index > 0.95). Premorbid traits were linked to body dissatisfaction and to the number of stressful life events; this in turn was linked to AN symptoms. Biological and familial consequences reinforced this pathology. CONCLUSIONS: Our findings provide support for both models, suggesting that inter relationships between bio-psycho-familial variables can influence the course of AN during adolescence.

Examining associations between obesity and mental health disorders from childhood to adolescence: A case-control prospective study.

Childhood obesity and mental disorders often co-exist. To date, most of the studies are cross-sectional, involve the assessment of a specific disorder, and rely on self-report questionnaires. This study aimed to provide a comprehensive psychological assessment to examine the concurrent and prospective association between childhood obesity and mental health problems. We compared 34 children with obesity with 37 children with normal weight at baseline, and at a five-year follow-up, to examine the development of mental health disorders from childhood (8-12 years) to adolescence (13-18 years). Both assessments included a clinical interview and self-reported measures of psychosocial and family markers. Findings showed that the obesity group had a higher prevalence of mental disorders, and psychological comorbidity increased in five years. Prospectively, childhood obesity was associated with a psychological diagnosis in adolescence. Moreover, the obesity group displayed higher severity of symptoms at both times. Finally, body esteem contributed to predicting mental health disorders in adolescence regardless of weight status, while eating symptomatology was a specific marker for the obesity group. Therefore, in the management of childhood obesity is suggested to address also psychosocial variables such as weight-related teasing and body esteem, to prevent the onset or development of mental health problems.

Spanish validation of two social media appearance-related constructs associated with disordered eating in adolescents: The Appearance-related Social Media Consciousness scale (ASMC) and the Critical Thinking about Media Messages scale (CTMM).

Appearance-related constructs underlying social media are negatively associated with mental health. However, their impact on the Spanish population is still unexplored. The present study aimed to validate the Spanish versions of two appearance-related scales: (1) the appearance-related social media consciousness (ASMC) scale; and (2) the critical thinking about media messages (CTMM) scale. Translation and cultural adaptation of the scales were carried out. The scales' psychometric properties were assessed using exploratory and confirmatory factor analyses, measurement invariance across gender (boys vs. girls) and age groups (early adolescents vs. middle adolescents), internal consistency, and convergent validity. The sample included 803 Spanish secondary school adolescents aged between 12 and 18 (Mage = 15.1, 47.9% girls, 47.2% boys, 4.9% non-binary gender/others). The exploratory factor analyses replicated original one-factor structures of both scales, which was verified using confirmatory factor analysis. Regarding the ASMC Scale, a re-specified model (allowing for error correlations between Items 1-2) presented an adequate fit. Both models were invariant across gender and age groups. Excellent internal consistency was found. Bivariate correlations between the ASMC and eating disorders related variables (body esteem, disordered eating, self-esteem, sociocultural attitudes towards appearance, and general mental health) supported its convergent validity and proved ASMC to be a potential target for future preventive eating disorder interventions. However, the CTMM scale correlated only with sociocultural pressures, thus, further research is needed to assess the validity of the CTMM in Spanish samples.

Physical Appearance Perfectionism: Psychometric Properties and Factor Structure of an Assessment Instrument in a Representative Sample of Males.

Perfectionism is a multidimensional construct with both positive and negative aspects. Recently, the concept of appearance-oriented perfectionism has been introduced, which is associated with body image dissatisfaction and weight and shape control behaviors. The Physical Appearance Perfectionism Scale (PAPS) is a 12-item two-factor instrument developed to assess this new dimension of perfectionism. The aim of the study is to validate the Spanish version of PAPS among a representative sample of 850 male university students in Spain (M = 20 years old; SD = 2.7). Exploratory and confirmatory factorial structure, internal consistency, convergent and concurrent validity, and associated predictor variables analyses have been carried out. Results showed that the Spanish version of the PAPS maintains the original factor structure with all items and proves to be a reliable instrument. Physical appearance-oriented perfectionism is associated with general perfectionism, higher body dissatisfaction, Eating Disorders and Muscle Dysmorphia symptomatology, and compulsive exercise, particularly in the Worry about Imperfection subscale. These variables also act as predictors of physical appearance perfectionism. The use of the PAPS-S and the analysis of its subscales is recommended in the context of body image-related pathologies such as Eating Disorders and Muscle Dysmorphia.

ENTREN-F family-system based intervention for managing childhood obesity: Study protocol for a randomized controlled trial at primary care.

BACKGROUND: Pediatric obesity is a primary public health concern, and designing effective programs for managing it is of the utmost importance. The objective of this study was to describe the protocol study of a three-arm, parallel, randomized controlled trial aimed at assessing the efficacy of a family-system-based intervention ("ENTREN-F" program) for managing childhood obesity, compared to the "ENTREN" program (no "F" - without specific family-system-based workshop) and a control group (behavioral monitoring). METHODS/DESIGN: The ENTREN-F program was a multicomponent family-system-based intervention carried out by a multidisciplinary team in the primary health care setting. The program targeted children between 8 and 12 years with overweight and obesity (P ≥ 85th). Parents were actively involved in the process. The contents were designed using the Cognitive Behavioral Therapy (CBT) principles. The program comprised individual behavioral monitoring, a healthy habits workshop for children and their parents, a CBT workshop for children, and a family-system-based workshop for parents, enhancing parental management skills plus family functioning. The trial's primary outcomes included changes in child body mass index (BMI) z-scores, child's psychological well-being, and family functioning over six months. Secondary outcomes included changes in eating behavior, physical activity, self-esteem, parental distress, parental feeding practices, and parental modeling. DISCUSSION: To our knowledge, this is one of the few randomized controlled trials to assess the efficacy of a multicomponent program that considers health from a comprehensive perspective, trying to improve children's psychological well-being and family functioning besides weight loss. This study, therefore, addresses a gap in the literature. If found to be efficacious, it suggests a new potential health service for translation into National Primary Health Care services in Spain, one of the ten countries with the highest prevalence of obesity in Europe.

Cognitive interpersonal maintenance model of eating disorders: intervention for carers.

BACKGROUND: Carers of people with eating disorders report high levels of distress. In addition, carers' responses to the illness may perpetuate eating disorder symptoms. A cognitive interpersonal maintenance model of eating disorders is proposed and interventions for carers may improve well-being in both carers and patients. Aims To examine an interpersonal maintenance model of eating disorders, using a self-help intervention for carers. METHOD: A pre-test-post-test design was used with carers randomised into self-help or guided self-help, which included the Expert Carers Helping Others (ECHO) intervention. Carers' distress, well-being, proposed maintenance factors, and carer reports on the status of the patient were measured. RESULTS: Carers' distress reduced and secondary outcomes improved. Improvement in carers' status and perceived improvements in patients were associated with reductions in expressed emotion and in accommodating and enabling behaviours. Self-help and guided self-help versions were comparable. CONCLUSIONS: Changes in maintenance factors from the theoretical model were associated with a reduction in carers' distress and improvement in perceived patient functioning. Interventions which specifically target maintaining factors may be of benefit.

Linking Psychosocial Stress Events, Psychological Disorders and Childhood Obesity.

There is scientific evidence that supports a strong association between early exposure to stressful life events and the presence of health complications throughout adulthood and, to a lesser extent, in adolescence and childhood. The aim of this study was to examine the accumulation of Psychosocial Stress Events (PSE) and the prevalence of mental disorders in children from 8 to 12 years. The association between these factors and child weight measurements was analysed. A cross-sectional study was conducted among 200 children classified by weight status (obesity, overweight and normal-weight). The assessment was carried out in primary care centres and primary schools. An experienced team carried out a structured medical-psychosocial history and a semi-structured interview aimed at identifying an early diagnosis of psychological disorders. Children filled out a questionnaire to evaluate PSE. The obesity group presented the greatest accumulation of PSE and highest prevalence of psychiatric diagnosis, compared to overweight and normal-weight children. To exceed four or more stressful events was positively associated with psychological problems and child body mass index (BMI z-score). A predictive model confirmed the interaction between a larger number of PSE and the occurrence of a psychiatric diagnosis as variables that predispose children by 26.2 times more to increased weight status. In conclusion, the accumulation of PSE in the family, school and social environments of the children was related to greater psychological distress. If not managed, the likelihood of suffering from other health complications, such as excess weight, may increase. It is important to monitor these variables to ensure positive health outcomes while specifically addressing childhood obesity. This is especially relevant for children from a disadvantaged social background and disharmonious family environments.

Toward a Biological, Psychological and Familial Approach of Eating Disorders at Onset: Case-Control ANOBAS Study.

Eating disorders (ED) are considered as heterogeneous disorders with a complex multifactor etiology that involves biological and environmental interaction. Objective: The aim was to identify specific ED bio-psychological-familial correlates at illness onset. Methods: A case-control (1:1) design was applied, which studied 50 adolescents diagnosed with ED at onset (12-17 years old) and their families, paired by age and parents' socio-educational level with three control samples (40 with an affective disorder, 40 with asthma, and 50 with no pathology) and their respective families. Biological, psychological, and familial correlates were assessed using interviews, standardized questionnaires, and a blood test. Results: After performing conditional logistic regression models for each type of variable, those correlates that showed to be specific for ED were included in a global exploratory model (R 2 = 0.44). The specific correlates identified associated to the onset of an ED were triiodothyronine (T3) as the main specific biological correlate; patients' drive for thinness, perfectionism and anxiety as the main psychological correlates; and fathers' emotional over-involvement and depression, and mothers' anxiety as the main familial correlates. Conclusion: To our knowledge, this is the first study to use three specific control groups assessed through standardized interviews, and to collect a wide variety of data at the illness onset. This study design has allowed to explore which correlates, among those measured, were specific to EDs; finding that perfectionism and family emotional over-involvement, as well as the T3 hormone were relevant to discern ED cases at the illness onset from other adolescents with or without a concurrent pathology.

Identifying Loss of Control Eating within Childhood Obesity: The Importance of Family Environment and Child Psychological Distress.

This study aims to examine the differences in family environment, psychological distress, and disordered eating symptomatology between children classified by weight status with or without loss of control (LOC) eating and to test a model of the role of emotional regulation of LOC eating based on a dysfunctional family environment. A cross-sectional study was conducted among 239 families. The assessment measured family expressed emotion, family adaptability and cohesion, child levels of depression and anxiety, body esteem, and disordered eating attitudes. The assessment was carried out in primary care centers and primary schools. Child body mass index (BMI) was associated with higher expressed emotion, psychological distress, and disordered eating symptomatology. Children with obesity and LOC presented higher BMI, poorer body esteem, and more disordered eating attitudes than children without LOC. Children with overweight/obesity, both with or without LOC, exhibited higher psychological distress and emotional overinvolvement than normal-weight children. A partial mediation of depression or anxiety and disordered eating attitudes between expressed emotion and LOC was found. Findings support that children with overweight/obesity show more family and psychological distress. Body esteem issues and disordered eating attitudes could alert the presence of LOC in children with obesity. The function of LOC might be to cope with psychological distress that may appear in a dysfunctional family environment.

The adolescent onset anorexia nervosa study (ANABEL): Design and baseline results.

The anorexia nervosa adolescent longitudinal biomarker assessment study (ANABEL) is a 2-year longitudinal study. OBJECTIVE: Evaluate several clinical, biochemical, immunological, psychological, and family variables and their interactions in adolescent onset eating disorders (EDs) patients and their 2-year clinical and biological outcome. This article illustrates the framework and the methodology behind the research questions, as well as describing general features of the sample. METHODS: A longitudinal study of 114 adolescents with EDs seeking treatment was performed. Only adolescents were selected during 4 years (2009-2013). The variables were collected at different times: baseline, 6, 12, 18, and 24 months of the start of treatment. Diagnoses were completed through the semi-structured Kiddie-Schedule for Affective Disorders and Schizophrenia interview. RESULTS: At baseline, the mean age was 15.11 (SD = 1.36). The mean ED duration was 10 months (SD = 5.75). The mean body mass index was 16.1 (SD = 1.8). The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnosis at baseline for restrictive anorexia nervosa was 69.6%, 17.4% for purgative anorexia nervosa, and 24.3% for other specified feeding disorder. At 12 months, 19.4% were in partial remission, whereas at 24 months, 13.8% had fully recovered and 29.2% had partially recovered. CONCLUSIONS: There was an acceptable physical and psychopathological improvement during the first year of treatment, with recovery being more evident during the first 6 months.

A meta-analysis of the diagnostic accuracy of the SCOFF.

A meta-analysis was conducted to reach a pooled estimate of the diagnostic accuracy of the SCOFF. The 15 selected studies represented a total of 882 cases and 4350 controls. The main criterion for inclusion was that the primary study had provided diagnostic classification with both a diagnostic reference and with the SCOFF (with five items and a cut-off point of two). The pooled estimates were .80 (sensitivity) and .93 (specificity). The moderator variables gender and type of measure for the diagnostic reference (interview versus psychometric tests) account for part of the observed variability. For diagnostic references based on interviews the estimate of the efficacy improves significantly. For the studies that match this criterion the sensitivity is .882 and the specificity .925 (diagnostic odds ratio, 92.19). The main conclusion was that the five questions of the SCOFF constitute a very useful screening tool, in several languages; it is highly recommended for screening purposes.

An examination of the impact of "the Maudsley eating disorder collaborative care skills workshops" on the well being of carers: a pilot study.

BACKGROUND: Carers of people with eating disorders experience high levels of distress due to the difficulties in their care giving role and their perceived lack of resources to help their relative. This paper describes an intervention where some of the skills used by specialist nurses and other staff from an eating disorder intensive care setting are taught to carers to improve their sense of competency and alleviate their distress. The aim of this study was to examine the feasibility and acceptability of "the Maudsley eating disorder collaborative care skills workshops" programme among care givers and whether the difficulties and distress involved in caring for a person with an eating disorder were reduced. METHODS: Thirty-five carers from 30 families were invited to participate in this programme, which consisted of a total of six workshops, delivered in 2-h sessions over 3 months. Assessments were undertaken at baseline (T0), at the end of the workshops (T1) and 3 months later (T2). RESULTS: The level of carer distress (GHQ) fell significantly after the intervention. The level of general care giving burden (ECI) also reduced as did the specific difficulties caused by eating disorder symptoms (EDSIS). These changes were maintained over time (T2). CONCLUSIONS: The transfer of specialist skills within the programme was highly valued by the carers and lessened their stress and care giving difficulties.
