Evaluation of the reliability and validity of the Italian version of the schema mode inventory for eating disorders: short form for adults with dysfunctional eating behaviors

A mixed methods study of schema modes amongst people living with eating disorders

BACKGROUND

Schema therapy is promising for people with eating disorders, especially those unresponsive to cognitive behavioural therapy. Complex underlying psychological constructs include dysfunctional schemas and maladaptive modes. This study aimed to explore people living with eating disorders' schema modes and their identification with and understanding of their high scoring modes.

METHODS

Sixteen women with enduring eating disorders without prior exposure to schema therapy completed the schema mode inventory for eating disorders short form (SMI-ED-SF), then participated in semi-structured interviews discussing their high scoring modes. Interviews were analysed by thematic analysis.

RESULTS

All participants scored above clinical concern on at least one maladaptive mode and many scored high on multiple modes, most commonly Demanding Mode, Vulnerable Child and Detached Self-Soother. Qualitatively, four themes emerged: 1) Adverse family environments related to (a) trauma and the vulnerable and angry child and (b) unrealistically high standards; 2) Mode effects on (a) everyday life and (b) disordered eating; 3) Modes are psychologically protective in (a) avoiding emotion by detachment and soothing, (b) people pleasing by compliance and surrender; 4) Help seeking including (a) barriers to recovery from an eating disorder, (b) dissatisfaction with interventions experienced to date, (c) schema therapy as a promising alternative.

DISCUSSION

Participants recognised and identified with their high scoring schema modes. After negative experiences with previous interventions, they considered schema therapy to be a promising alternative that could understand and work on their deeper psychological issues. This suggests that schema modes are a promising way of understanding and working with enduring eating disorders.

Artificial Neural Networks for Short-Form Development of Psychometric Tests: A Study on Synthetic Populations Using Autoencoders

Short-form development is an important topic in psychometric research, which requires researchers to face methodological choices at different steps. The statistical techniques traditionally used for shortening tests, which belong to the so-called exploratory model, make assumptions not always verified in psychological data. This article proposes a machine learning-based autonomous procedure for short-form development that combines explanatory and predictive techniques in an integrative approach. The study investigates the item-selection performance of two autoencoders: a particular type of artificial neural network that is comparable to principal component analysis. The procedure is tested on artificial data simulated from a factor-based population and is compared with existent computational approaches to develop short forms. Autoencoders require mild assumptions on data characteristics and provide a method to predict long-form items' responses from the short form. Indeed, results show that they can help the researcher to develop a short form by automatically selecting a subset of items that better reconstruct the original item's responses and that preserve the internal structure of the long-form.

Brazilian instrument for assessing of eating disorders in children and adolescents

OBJECTIVE

This study aimed to develop the Brazilian instrument for assessing eating disorders in children and adolescents and test its psychometric quality using item response theory (IRT).

DESIGN

Cross-sectional study.

PARTICIPANTS

Participants aged between five and twelve years old of both sexes.

MAIN MEASURES

IRT logistic model of two parameters was used to evaluate the item's severity and discrimination and test information curve of symptoms of eating disorders' latent trait symptoms. Content validity and reliability were also assessed. The IRT evaluation suggested that the instrument contained items that performed differently concerning severity, discrimination, and test information curve presented good accuracy.

RESULTS

There was agreement on the clarity of language (83.3%) and theoretical relevance (91.7%), indicating good content validity. The value of the Cronbach's Alpha was 0.63 (95% confidence interval), and the result of the Spearman-Brown test was 0.65.

CONCLUSION

These results indicate good performance of the screening tool in assessing the level of eating disorders in children and adolescents.

Willingness to Compromise Scale: Italian Validation and Assessment of the Relationship with Career Decision Self-Efficacy and Career Adaptability during School-to-Work Transition

Willingness to compromise is defined as the propensity to accept an alternative career-related option that was not the one initially desired. In the literature, there is a validated scale for measuring willingness to compromise but not an Italian validation. Thus, Study 1 aimed to test the psychometric proprieties of the Willingness to Compromise Scale in a sample of 282 Italian university students. Confirmatory factor analyses were performed showing a second-order factorial structure with two well-separated first-order factors, i.e., compromising and adapting. Study 2 focused on the predicting role of willingness to compromise on career decision self-efficacy and the mediating role of career adaptability in this relationship. The sample consisted of 237 Italian university students. A mediation analysis with a 5000-bootstrap resampling procedure was computed. The results showed that willingness to compromise predicts both career decision self-efficacy and career adaptability, while career adaptability mediates the relationship between willingness to compromise and career decision self-efficacy. These findings allowed the discussion of practical implications for career guidance intervention aimed to support school-to-work transitions.

The Rising of the Shield hero. Development of the Post-Traumatic Symptom Questionnaire (PTSQ) and Assessment of the Protective Effect of self-esteem from trauma-related Anxiety and Depression

Background

Adverse life events such as life-threatening accidents, domestic and/or sexual violence, organic diseases (i.e., cancer), or COVID-19 can have a strong traumatic impact - generating reactions as intrusive thoughts, hyperarousal, and avoidance. Indeed, the traumatic impact of COVID-19 seems to lead individuals to experience anxiety and depression. However, the Anxiety-Buffer Hypothesis suggests that self-esteem could be considered a shield (buffer) against traumatic experiences and their outcomes (i.e., anxiety and depression). The present study has two objectives. First, to develop a measure of the impact of the traumatic event considering the aforementioned reactions. Second, to test the process - triggered by COVID19-related traumatic experience - in which self-esteem buffers the path that leads to anxiety and depression.

Method

In Study 1 (N = 353), the Post-Traumatic Symptom Questionnaire (PTSQ) was developed and a deep investigation of its psychometric properties was conducted. In Study 2 (N = 445), a structural equation model with latent variables was performed to assess the buffering effect of self-esteem.

Results

The PTSQ has excellent fit indices and psychometric properties. According to the ABH, results confirm the buffering effect of self-esteem in the relationships between traumatic symptoms and both anxiety and depression.

Conclusion

On the one hand, the PTSQ is a solid and reliable instrument. On the other hand, that self-esteem is a protective factor against anxiety and depression related to a traumatic experience - such as COVID-19. Targeted psychological interventions should be implemented to minimize the psychological burden of the illness while promoting adaptation and positive aspects of oneself.

Weight stigma in patients with overweight and obesity: validation of the Italian Weight Self-Stigma Questionnaire (WSSQ)

PURPOSE

This study aimed to explore the factorial structure of the Italian Weight Self-Stigma Questionnaire (WSSQ) (Study1); and to test structural validity, internal consistency, test-retest reliability, and measurement invariance of the questionnaire across gender, Body Mass Index (BMI), age and occurrence of previous hospitalization for obesity (Study2).

METHODS

At admission into a hospital-based program for weight reduction and rehabilitation, 150 inpatients with overweight/obesity (68% females) completed the WSSQ (Study1). In Study2, in addition to the WSSQ, 446 inpatients (61.9% females) completed the Weight Bias Internalization Scale (WBIS), the Body Uneasiness Test (BUT), and the Center for Epidemiologic Studies Depression Scale (CES-D). A subsample of 40 patients also re-completed the WSSQ at discharge from the hospital.

RESULTS

The Italian WSSQ showed good overlap with the original factorial structure (Study1) and results were confirmed in Study2. Test-retest reliability and convergent validity showed adequate values. Measurement invariance revealed that WSSQ was perfectly invariant across both BMI and the occurrence of previous hospitalizations for obesity. In both studies, the internal consistency of the questionnaire was deemed acceptable.

CONCLUSIONS

The Italian WSSQ is a valid, reliable, and invariant tool for the assessment of weight-related self-stigma among patients with overweight/obesity. Future studies should assess its longitudinal invariance as well as its responsiveness to weight reduction treatments.

Screening for Distress in Oncological Patients: The Revised Version of the Psychological Distress Inventory (PDI-R)

Background

Psychological research in oncological settings is steadily increasing and the construct of psychological distress has rapidly gained popularity-leading to the development of questionnaires aimed at its measurement. The Psychological Distress Inventory (PDI) is one of the most used instruments, but its psychometric properties were not yet deeply evaluated. The present studies aimed at investigating the psychometric properties of the PDI (Study 1) and providing a revised version of the tool (Study 2).

Methods

Oncological outpatients were enrolled at the Department of Medical Oncology of the Presidio Ospedaliero of Saronno, ASST Valle Olona, Italy. For the first study (N = 251), an Exploratory Graph Analysis was used to explore the item structure of the PDI. In the second study (N = 902), the psychometric properties of the revised PDI (PDI-R) were deeply assessed.

Results

Study 1 showed that the PDI has a not clear structure and it should be reconsidered. On the opposite, Study 2 showed that the revised version (PDI-R) has a solid factorial structure, it is invariant across gender and age, and it has good psychometric properties.

Conclusion

Results suggest that the PDI-R is a reliable measure of psychological distress in different samples of oncological patients, with stronger psychometric properties than the original version. Its use in the clinical and research field is therefore recommended to improve the quality of both assessment and treatment of psychological distress in patients with oncological problems.

Parental-Bonding and Alexithymia in Adolescents with Anorexia Nervosa, Their Parents, and Siblings

Anorexia nervosa (AN) patients and their family-members share alexithymia, anxiety, depression, and other psychological symptoms, in the context of altered attachment. These domains have been individually studied in the context of eating disorders; few attempts have been made to study their interaction, especially including family members. In this study, alexithymia, parental-bonding, and psychopathology were assessed in 32 Italian families consisting of an adolescent AN patient, a sibling, and their parents. We aimed to (a) describe a sample of Italian families with a child affected by AN, notably including siblings; (b) investigate interactions between assessed constructs in patients and their siblings; and (c) investigate possible intergenerational effects. Results showed high alexithymia and psychopathological symptoms in patients but not in siblings, although the latter reported high obsession-compulsion and paranoid ideation scores. Patients' and siblings' alexithymia correlated with psychopathology. Parents reported generally low alexithymia. Perceived parental bonding was found to be suboptimal in most participants, yet no clear relationship was found between specific parenting styles and other measured traits, nor did we find any other relevant intergenerational effect. Anorexia nervosa implies psychological difficulties for all family members. Siblings' psychopathological traits are especially concerning and currently understudied. Implications for future research and clinical interventions are discussed.

Validation of the body image dimensional assessment in adolescents from Spanish high school

INTRODUCTION

There are not many valid instruments to quickly and easily identify body dissatisfaction in adolescents. Most studies have used the Stunkard Rating Scale to assess body image. Nevertheless, this scale has been described as too abrupt and crude for adolescents.

AIM

Was to validate the body image dimensional assessment (BIDA) questionnaire in a sample of adolescents from Secondary schools of Spain.

METHOD

The BIDA consists of four items to answer with reference to a series of four silhouettes using a numeric scale that allows the quantification of the degree of body dissatisfaction (BD), sexual body dissatisfaction (SxBD), comparative body dissatisfaction (CBD) and the calculation of the final body dissatisfaction index (BDIndex). The sample included 2059 adolescents, 1132 males and 929 females aged 13.10 ± 0.89. Participants answered the BIDA and then their anthropometrics measurements were taken.

RESULTS

Reliability test, a convergent test and confirmatory factorial analysis were conducted to validate BIDA instrument. A single factor structure emerged from confirmatory factorial analysis; the BIDA demonstrated adequate internal consistency in adolescents: (CFI > 0.90, TLI > 0.90, α > 0.80). Significant correlations (p < 0.001) emerged between the BIDA indices and all the anthropometric measures.

CONCLUSIONS

The BIDA questionnaire is a valid and reliable instrument to evaluate body dissatisfaction in Spanish adolescents.

From Fear to Hopelessness: The Buffering Effect of Patient-Centered Communication in a Sample of Oncological Patients during COVID-19

Background: COVID-19 represents a threat both for the physical and psychological health of oncological patients experiencing heightened distress levels to which the fear of the virus is also added. Moreover, fear of COVID-19 could lead oncological patients to experience feelings of hopelessness related to their medical care. Patient-centered communication may act as a buffer against the aforementioned variables. This study aimed to test the role of doctor–patient communication in the relationship between fear of COVID-19 and hopelessness. Methods: During the COVID-19 pandemic, a sample of 90 oncological outpatients was recruited (40 males (44.4%) and 50 females (55.6%), mean age = 66.08 (SD = 12.12)). A structured interview was developed and used during the pandemic to measure the patients’ perceived (A) fear of COVID-19, and (B) feelings of hopelessness, and (C) physicians’ use of empathetic and (D) clear language during the consultation. A multiple mediation model was tested, and the effects between males and females were also compared. Results: Empathetic and clear doctor–patient communication buffered the adverse effect of the fear of COVID-19 on hopelessness through a full-mediation model. The effects did not differ between males and females in the overall model but its indirect effects. Discussions: Patient-centered communication using empathy and clear language can buffer the adverse effect of the fear of COVID-19 and protect oncological patients from hopelessness during the pandemic. These findings might help to improve clinical oncological practice.

Psychological Differences Among Healthcare Workers of a Rehabilitation Institute During the COVID-19 Pandemic: A Two-Step Study

Introduction: Healthcare workers facing the threatening COVID-19 can experience severe difficulties. Despite the need to evaluate both the psychological distress and positive protective resources, brief and reliable assessment tools are lacking. Aim: Study 1 aimed at developing a new assessment tool to measure psychological distress and esteem in healthcare workers during the COVID-19 pandemic. Study 2 aimed to explore and compare the psychological reactions of healthcare workers of the COVID-19 and the non-COVID-19 wards. Methods: In Study 1, psychologists created 25 items based on their clinical experience. A preliminary qualitative evaluation selected the best 15 items for the new tool (CPI-HP) assessing the COVID-19 psychological impact with 2 scales: psychological distress and esteem. The CPI-HP was administered to 110 healthcare professionals to study its psychometric properties and the internal structure with exploratory graph analysis and confirmatory factor analysis. Study 2 compared two groups of healthcare professionals of the COVID-19 and non-COVID-19 departments. Results: In Study 1, the CPI-HP showed satisfying psychometric properties, and the two-factor structure was confirmed with good fit indices. In Study 2, the two groups of healthcare workers showed comparable levels of psychological distress and resilient coping, but the COVID-19 group displayed significantly higher esteem and appreciation of the experience. Discussion: All operators showed high psychological distress during the emergency, but the COVID-19 group reported higher resources, probably due to stronger group cohesion and greater esteem, perceived meaning, and own work value. Conclusion: Assessing the psychological distress and resources of healthcare professionals with specific tools is important. Psychological interventions should promote their psychological health.

The Psychological Experience and Intervention in Post-Acute COVID-19 Inpatients

PURPOSE

COVID-19 patients faced first-hand the life-threatening consequences of the disease, oftentimes involving prolonged hospitalization in isolation from family and friends. This study aimed at describing the psychological intervention to address the psychological difficulties and issues encountered by the hospitalized post-acute COVID-19 patients in a rehabilitation setting.

PATIENTS AND METHODS

Patients' demographics, medical diagnosis, and neuro-psychological information were collected from March 2nd to May 12th, 2020. The main psychological issues and intervention strategies were collected.

RESULTS

A total of 181 patients were hospitalized during this period. Among them, the 47.5% underwent psychological assessment (N=86; age: 74.58±13.39; 54.7% females). The most common psychological issues were acute stress disorders (18.6%), anxious and demoralization symptoms (26.7%), depression (10.5%%), and troublesome grief (8.1%). Once recovered from COVID-19, many patients were discharged home (38.4%), some received further rehabilitation in non-COVID-19 wards (41.9%), mostly due to pre-existent diseases (72.2%) rather than to COVID-19 complications (27.8%).

CONCLUSION

A great number of the hospitalized post-acute COVID-19 patients showed psychological issues requiring psychological intervention, the most common were anxiety, demoralization, acute stress, depression, and grief. The proposed psychological treatment for hospitalized COVID-19 patients was conducted in a Cognitive Behavioral framework. In particular, during the COVID-19 pandemic, psychological intervention is an important part of rehabilitation in the post-acute phase of the illness to reduce distress symptoms and improve psychological health.

Structural validity, measurement invariance, reliability and diagnostic accuracy of the Italian version of the Yale Food Addiction Scale 2.0 in patients with severe obesity and the general population

PURPOSE

To examine the structural validity, measurement invariance, reliability, and some other psychometrical properties of the Italian version of the Yale Food Addiction Scale 2 (I-YFAS 2.0) in patients with severe obesity and the general population.

METHODS

704 participants-400 inpatients with severe obesity and 304 participants enrolled from the general population-completed the I-YFAS 2.0 and questionnaires measuring eating disorder symptoms. A first confirmatory factor analysis (CFA) tested a hierarchical structure in which each item of the I-YFAS 2.0 loaded onto one of the twelve latent symptoms/criteria which loaded onto a general dimension of Food Addiction (FA). The second CFA tested a first-order structure in which symptoms/criteria of FA simply loaded onto a latent dimension. Measurement invariance (MI) between the group of inpatients with severe obesity and the sample from the general population was also tested. Finally, convergent validity, test-retest reliability, internal consistency, and prevalence analyses were performed.

RESULTS

CFAs confirmed the structure for the I-YFAS 2.0 for both the hierarchical structure and the first-order structure. Configural MI and strong MI were reached for hierarchical and the first-order structure, respectively. Internal consistencies were shown to be acceptable. Prevalence of FA was 24% in the group of inpatients with severe obesity and 3.6% in the sample from the general population.

CONCLUSIONS

The I-YFAS 2.0 represents a valid and reliable questionnaire for the assessment of FA in both Italian adult inpatients with severe obesity and the general population, and is a psychometrically sound tool for clinical as well as research purposes.

Gender differences and long-term outcome of over 75 elderlies in cardiac rehabilitation: highlighting the role of psychological and physical factors through a secondary analysis of a cohort study

BACKGROUND

Despite cardiac rehabilitation for elder people already showed its usefulness, to date it is still not clear the impact of gender and of psychological constructs in influencing the rehabilitation outcomes.

AIM

This study aimed at exploring the gender differences of great elders (over 75 years old) in cardiac rehabilitation, with particular attention to the impact of physical and psychological conditions, as depressive symptoms, on long-term post-discharge outcomes.

DESIGN

A cohort study design was used and a secondary analysis was conducted.

SETTING

Cardiac rehabilitation unit of a postacute rehabilitation Institute.

POPULATION

Elderly patients over 75 years old admitted to the cardiac rehabilitation program.

METHODS

Psychological and functional variables, such as Barthel Index, BMI, quality of life, and depression measured at admission and discharge from CR were matched with mortality information up to 4 years, used as long-term outcomes.

RESULTS

A total of 523 patients, 228 females and 295 males, with a mean age of 76.27 years±3.46 were progressively enrolled. Barthel index at admission and discharge was higher for males than females, 74.10±17.31 vs. 68.90 SD±16.81 (P<0.001), and 95.45±10.64 vs. 92.95±13.03 (p=0.021), respectively, while the relative change from admission to discharge Δ% of Barthel was higher for females 0.25±0.18 than for males 0.21±0.17 (P<0.05). Compared to males, either at admission or discharge females presented more severe depressive symptoms (5.21±3.46 vs. 3.86±2.79, P<0.001; 4.15±3.21 vs. 2.93±2.45, P<0.001) and a worse quality of life (10.58±2.15 vs. 9.55±2.24, P<0.001; 7.5±1.63 vs. 7.02±1.08, P=0.018). Cox proportional analysis revealed that female gender, depression at discharge, Barthel, and Comorbidity Index were associated with higher hazard and shorter survival time. On the other hand, higher BMI was associated with lower hazard and longer survival time.

CONCLUSIONS

Elderly women following a CR program present more disability, depression, and a worse QoL than men. Obviously, these characteristics influence the length of hospitalization but with significant improvement. Despite the frail-gender paradox regarding survival, after CR program women have a higher risk of mortality than men. Depression has a significant negative impact on elderly psychophysical health.

CLINICAL REHABILITATION IMPACT

Gender-specific and individualized rehabilitation programs should be implemented by considering the discussed physical and psychological risk factors. Further insight about gender differences among over 75 elderlies in CR is provided, this knowledge may be useful for clinicians scheduling recovery plans to promote elderlies' psychological and physical health. Psychological interventions should be implemented to relieve the depressive symptoms among elders.

Assessing Psychometric Properties of the Italian Version of the Heartland Forgiveness Scale

Despite increasing popularity and intensive worldwide use, few studies have assessed the validity and factorial structure of the Heartland Forgiveness Scale (HFS). However, scientific literature showed that the original factorial structure of the HFS was not fully replicated and—in addition—the Italian translation is still lacking. To fill this gap, this study aims to extend evidence about the original HFS factorial validity by analyzing the Italian version. The final sample was composed of 523 randomly enrolled participants [139 males (26.6%), 384 females (73.4%)] aged from 18 to 82 years (mean = 42.53, SD = 16.41) who completed the Italian version of the HFS. The confirmatory factor analysis showed good fit indices for the original hierarchical factor solution and a significant decrease in model fit was found for all of the competing models. Also, the Italian version of the HFS revealed good reliability and very good psychometrical properties. Findings suggest that the Italian version of the HFS can be considered a reliable and good psychometrically based instrument for the assessment of dispositional forgiveness of the Self, Other, and Situation.

Development and Validation of a Self-Determination Theory-Based Measure of Motivation to Exercise and Diet in Children

Objective: To develop and test the factorial structure of a new self-determination theory–based measure of behavioral regulation in children.

Methods: Five hundred ninety 590 (F = 51.7%) children aged 7 to 11 years completed the Motivation to Exercise and Diet (MED-C) questionnaire, which comprises 16 items (eight for exercise and eight for diet) grouped into eight factors (five motivations and three needs). Psychometric testing included confirmatory factor analysis and internal consistency. Measurement invariance analyses were also performed to evaluate whether the factorial structure of the MED-C was equivalent for gender (male vs. female), age (≤9 vs. ≥10 years), and the perception of having at least one parent with overweight or obesity (yes vs. no).

Results: Factorial analysis confirmed an acceptable factors solution for the MED-C and a good fit to the data for both the exercise and the diet subscales assessed independently. The maximal reliability coefficient revealed good reliability for the exercise and the diet subscales. Moreover, the MED-C factor structure was invariant across group comparisons.

Discussion: Findings support the construct validity and reliability of the MED-C. Therefore, it represents the first validated instrument simultaneously measuring motivational regulation and psychological need satisfaction in the context of children’s exercise and diet. Considering the goodness of these results, scale percentile ranks of the total score distribution as well as the z score and the T score were provided for clinical and research purposes.

Conclusion: The MED-C might support the understanding of motivations and needs of children with weight problems and assist their process of behavioral change in primary and secondary prevention programs. Psychological factors represent, in fact, potential targets for interventions to increase children’s motivation to exercise and diet.

Development and psychometric properties of a short form of the Illness Denial Questionnaire

Background

Coping with chronic illness can be overwhelming for patients and caregivers, and may be inhibited by the denial mechanism, and therefore, denial represents a critical issue for health professionals. Assessing illness denial is far from easy, and brief tools suitable for medical settings are lacking. In this paper, the development of a short form of the Illness Denial Questionnaire (IDQ) for patients and caregivers is presented.

Methods

In study 1, the IDQ was administered to 118 patients and 83 caregivers to examine the internal structure of denial; then the properties of the items (DIF, fit, and difficulty) were evaluated according to the Rasch model in order to select the best items for the Illness Denial Questionnaire-Short Form (IDQ-SF). Study 2 included 202 participants (113 patients and 89 caregivers). The internal structure of the IDQ-SF was tested via confirmatory factor analysis (CFA). Reliability and concurrent validity were also studied using the Anxiety and Depression Questionnaire-Reduced Form (AD-R).

Results

The CFA showed a two-factor structure encompassing "Denial of negative emotions" and "Resistance to change". Results of the Rasch analyses led to the selection of 4 items for each dimension. The resulting IDQ-SF (8 items) showed a two-factor structure as well as good reliability and concurrent validity with AD-R.

Conclusion

The IDQ-SF represents a valid tool for quickly evaluating the core of illness denial in patients and caregivers. This brief and easily administrable questionnaire allows health professionals to outline the presence and severity of illness denial in order to set individually tailored interventions.
