Accommodation and Enabling Scale for Eating Disorders–Greek Version

Abstract

The Accommodation and Enabling Scale for Eating Disorders—Greek Version (AESED-Greek) is a specialized psychometric instrument adapted and validated by Lempesi, Katerinopoulou, Tzavara, Koumoula, and Gonidakis (2024) to quantify the interpersonal mechanisms through which caregivers accommodate and inadvertently perpetuate eating disorder (ED) symptomatology. Derived from the seminal instrument formulated by Janet Treasure and colleagues (Sepulveda, Kyriacou, & Treasure, 2009), this 33-item inventory assesses specific family behaviors that maintain pathology across anorexia nervosa, bulimia nervosa, and related conditions. Administered to parents and primary caregivers, the AESED-Greek captures five distinct empirical dimensions: Meal context ritual, Avoidance & modifying routine, Blind eye, Reassure seeking, and Control of family. Items are rated along a five-point Likert scale ranging from 0 (“never”) to 4 (“nearly always”), generating composite scores between 0 and 132, with higher scores reflecting elevated interpersonal accommodation.

Psychometric evaluation demonstrated outstanding internal consistency, evidenced by an overall Cronbach’s alpha coefficient of 0.93, with subscale reliabilities ranging from 0.78 to 0.90. Construct validity was corroborated via Principal Component Analysis (PCA), which confirmed a stable five-factor architecture accounting for 63% of the total variance, corroborating the factorial validity of the original English version while adapting item groupings to Greek familial contexts. Convergent validity was substantiated by robust positive correlations with the subscales of the General Health Questionnaire (GHQ-28), demonstrating that high family accommodation is closely linked to heightened parental psychological distress, caregiver burden, and maladaptive coping strategies. The AESED-Greek serves as a foundational assessment tool for systemic clinicians, family therapists, and clinical researchers operating within cross-cultural eating disorder frameworks.

Purpose

The primary clinical and psychometric objective of the AESED-Greek is to operationalize and measure the degree to which caregivers modify their daily behavioral patterns, emotional responses, and family functioning to prevent, mitigate, or manage distress related to an eating disorder in a family member. Family accommodation and enabling behaviors are well-documented systemic phenomena wherein family members—frequently parents or domestic partners—unintentionally collude with, facilitate, or tolerate the rigid and ritualistic symptoms manifested by an individual with an eating disorder.

In clinical practice, caring for a family member diagnosed with an eating disorder produces marked distress, confusion, and fear. Caregivers frequently encounter severe outbursts, intense emotional lability, refusal to consume meals, self-harm threats, or escalating ritualistic behaviors during mealtimes. To maintain household peace or alleviate the patient’s acute anxiety, parents systematically adjust family routines, alter purchasing habits, cook isolated menus, and yield to demanding or controlling behaviors. While such actions are motivated by protective instincts, empathy, or exhaustion, empirical evidence shows they reinforce behavioral avoidance, prevent inhibitory learning, normalize eating disorder rituals, and insulate the patient from experiencing the natural consequences of their illness.

The AESED-Greek provides clinicians and researchers with an objective instrument to:

• Identify specific, idiosyncratic patterns of family accommodation during initial diagnostic assessments;
• Quantify baseline levels of enabling behaviors prior to implementing family-based interventions, such as the New Maudsley Model or Family-Based Treatment (FBT);
• Evaluate therapeutic progress and systemic behavioral change across longitudinal treatment phases;
• Provide tailored psychoeducation to help parents recognize counterproductive behaviors and replace accommodating responses with supportive, non-collusive communication.

Psychological Construct

The core construct evaluated by the AESED-Greek is eating disorder accommodation and enabling. Borrowed from anxiety disorder and obsessive-compulsive disorder (OCD) psychopathology literature, accommodation represents the relational manifestations of illness-maintaining behaviors. The Greek adaptation mirrors the 33-item, five-dimensional structure originally delineated by Sepulveda et al. (2009):

1. Meal Context Ritual

This dimension encompasses the active facilitation and tolerance of eating-related rituals and food rigidities. It measures behaviors where caregivers comply with obsessive demands regarding dietary choices, meal preparation methods, utensil usage, and timing. Examples include cooking distinct multi-course meals tailored to the patient’s caloric restrictions, weighing ingredients to appease the patient, serving food at precise micro-temperatures, or permitting prolonged, ritualized chewing and food manipulation without setting functional boundaries.

2. Avoidance & Modifying Routine

This subscale evaluates the structural disruption of family life designed to circumvent confrontations or triggers. Caregivers progressively restructure social, domestic, and recreational schedules to conceal the disorder or shield the patient from everyday eating cues. Examples include declining social invitations, cancelling family vacations, avoiding restaurant dining, restricting host visits, or altering employment commitments to monitor or appease the patient’s anxiety around food.

3. Blind Eye

The “Blind eye” dimension assesses caregiver passivity, denial, and deliberate disengagement from active symptoms. Parents frequently experience profound burnout, fear of physical or emotional collapse in the patient, or pervasive helplessness. Consequently, they deliberately overlook conspicuous eating disorder pathology, such as excessive physical exercising, self-induced vomiting, ritualistic body-checking, hidden laxatives, or food hoarding. By ignoring these manifestations, caregivers temporarily avoid hostile conflicts, despite knowing that unaddressed symptoms permit clinical deterioration.

4. Reassure Seeking

This factor measures caregiver participation in repetitive cycles of compulsive reassurance. Patients with eating disorders frequently suffer from severe cognitive distortions regarding their body shape, weight, and caloric exposure. They persistently interrogate loved ones to confirm whether they look larger, whether an ingredient contains hidden fats, or whether a minimal food portion will cause immediate weight gain. This subscale measures the frequency with which caregivers get drawn into these circular dialogues, answering repetitive queries that provide transient emotional relief while reinforcing the patient’s obsessive distress.

5. Control of Family

The final dimension evaluates the extent to which the individual with the eating disorder exerts unilateral dominance over domestic rules, relational dynamics, and interpersonal space. This includes instances where the patient dictates grocery shopping lists, denies other family members access to the kitchen, monitors what siblings consume, commands room temperatures to manipulate caloric expenditure, or controls family conversation topics. High scores indicate an inversion of parental authority, leaving family members subordinate to eating disorder rules.

Theoretical Framework

The AESED is rooted in the Cognitive-Interpersonal Maintenance Model of Eating Disorders, developed by Treasure and Schmidt (2013) and expanded by Treasure et al. (2020). This model posits that while genetic, biological, and neurocognitive factors predispose individuals to conditions like anorexia nervosa, interpersonal processes within the domestic environment play a key role in maintaining chronicity.

When an individual develops an eating disorder, the resultant starvation, cognitive rigidity, and mood instability introduce severe chronic stress into the household. Caregivers naturally respond to this distress through distinct, patterned interpersonal coping styles, metaphorically characterized within the New Maudsley intervention framework:

• The “Jellyfish” Style: Emotional dysregulation, overwhelm, and an inability to maintain boundaries, leading directly to high levels of accommodation;
• The “Ostrich” Style: Experiencing overwhelming distress leading to behavioral disengagement, denial, and ignoring dangerous pathology (captured by the Blind eye subscale);
• The “Kangaroo” Style: Overprotective sheltering, insulating the patient from all emotional discomfort and taking over personal responsibilities, which reinforces symptom avoidance;
• The “Rhino” Style: Highly confrontational, hostile responses that trigger reactive entrenchment of the eating disorder.

The AESED-Greek specifically operationalizes the behavioral consequences of these interpersonal profiles. From an operant conditioning perspective, parental accommodation functions as an interpersonal safety behavior. When a parent modifies a meal or provides reassurance, the patient experiences immediate negative reinforcement via transient anxiety reduction. Similarly, the caregiver experiences immediate relief through the de-escalation of domestic conflict. However, this mutual reinforcement loop prevents natural extinction of fear, fuels cognitive intolerance of uncertainty, and sustains the eating disorder as the primary mediator of family interactions.

Validity

The validation study by Lempesi et al. (2024) established strong psychometric validity for the Greek translation across clinical samples of caregivers whose children were treated in specialized eating disorder units:

Construct and Factorial Validity

Construct validity was evaluated using Principal Component Analysis. The analysis confirmed a five-factor structure that explained 63% of the total cumulative variance, closely matching the original factor solution published by Sepulveda et al. (2009). All 33 items demonstrated robust factor loadings exceeding the standard 0.40 threshold. Minor cultural shifts were observed: specific items relating to meal management that cross-loaded on routine alteration in British samples grouped cleanly into the “Meal context ritual” domain in the Greek cohort. This grouping reflects the distinct cultural, culinary, and collective meaning of shared family mealtimes in Mediterranean contexts.

Convergent Validity

Convergent validity was evaluated by correlating AESED-Greek subscales and total scores against the General Health Questionnaire (GHQ-28), a validated measure of parental emotional distress, anxiety, insomnia, social dysfunction, and depressive symptomatology. The analyses revealed statistically significant, moderate-to-strong positive correlations between AESED dimensions and GHQ-28 indices. Elevated parental accommodation was systematically correlated with increased caregiver psychopathology, confirming the clinical observation that high family accommodation is closely linked with heightened caregiver psychological burden.

Discriminant and Clinical Validity

The instrument differentiated meaningfully between family members reporting varying durations of illness and functional impairment in patients. Parents of chronically ill individuals, or those exhibiting heightened illness severity, reported elevated AESED-Greek scores across the Meal context ritual and Control of family domains compared to parents navigating early-stage presentations, corroborating the progressive entrenchment of accommodation over time.

Reliability

The AESED-Greek demonstrates high internal consistency and measurement precision across its total scale and composite domains:

• Total Scale Internal Consistency: The 33-item inventory achieved an overall Cronbach’s alpha of 0.93, indicating exceptional internal homogeneity and minimal measurement error, closely matching the 0.92 coefficient reported for the original English index (Sepulveda et al., 2009).
• Subscale Alpha Coefficients:
  • Meal context ritual: $\alpha = 0.90$ (reflecting high consistency in measuring mealtime accommodation);
  • Avoidance & modifying routine: $\alpha = 0.88$;
  • Control of family: $\alpha = 0.85$;
  • Reassure seeking: $\alpha = 0.82$;
  • Blind eye: $\alpha = 0.78$ (a solid reliability level given the smaller item count and behavioral diversity in this subscale).
• Split-Half and Item-Total Statistics: Corrected item-total correlation coefficients across all 33 items remained above critical cut-offs ($r > 0.35$), confirming that each individual item contributes meaningfully to the overarching construct of family accommodation.

Factor Analysis

The psychometric structure was tested via exploratory Principal Component Analysis (PCA) using orthogonal (Varimax) and oblique rotations. The Kaiser-Meyer-Olkin (KMO) measure verified high sampling adequacy, and Bartlett’s Test of Sphericity confirmed significant correlation matrix factorability ($p < 0.001$).

Key findings from the factor analytic model include:

• Variance Explained: The extracted five-factor architecture accounted for 63% of the cumulative variance, a strong outcome for self-report behavioral measures in clinical psychology.
• Item Loadings: Every item loaded significantly on its designated primary factor (standardized loadings $lambda ge 0.40$), with primary saturation values ranging between 0.45 and 0.84.
• Factor Alignment: The empirical factors replicated the dimensional construct defined by Sepulveda et al. (2009): Component 1 represented Meal context ritual; Component 2 reflected Avoidance & modifying routine; Component 3 captured Control of family; Component 4 isolated Reassure seeking; and Component 5 captured Blind eye.
• Cross-Cultural Nuances: Certain items addressing kitchen management and family mealtimes consolidated more distinctly into the Meal context ritual factor than in the UK sample. The authors attributed this pattern to the central role of communal cooking and shared dining in Greek family life, where eating disruptions directly disrupt wider family dynamics.
