Abstract Purpose: Orthorexia Nervosa (ON) is described as an extreme level of preoccupation around healthy eating, accompanied by restrictive eating behaviors. During the years different assessment instruments have been developed. The aim of the study is to adapt into Italian the Düsseldorf Orthorexia Scale (I-DOS) and to test its psychometric properties. Method. A total sample of 422 volunteer university students (mean age = 20.70 ± 3.44, women 71.8%) completed a group of self-report questionnaires in large group sessions during their lecture time. The scales assessed ON (the I-DOS and the Orhto-15), disordered eating (Disordered Eating Questionnaire, DEQ), depressive symptoms (Beck Depression Inventory-II, BDI-II), obsessive and compulsive symptoms (Obsessive Compulsive Inventory-Revised, OCI-R) and self-reported height and weight. Results: The fit of the unidimensional structure and reliability of the I-DOS was tested trough Confirmatory Factor Analysis (CFA) as well as its criterion validity computing correlation coefficients among Ortho-15, DEQ, BDI-II, OCI-R, BMI. Analyses confirmed the unidimensional structure of the I-DOS with acceptable or great fit indices (CFI = 0,984; TLI = 0,978; SRMR = 0.043; RMSEA = 0.076) and the strong internal consistency (α = .888). The Correlations path supported the criterion validity of the scale. The estimated prevalence of ON and ON risk was 8.1%.Conclusions: This 10-items scale appears to be a valid and reliable measure to assess orthorexic behaviors and attitudes.

During the years, different assessment instruments have been developed. The aim of the study is to adapt into Italian the Düsseldorf Orthorexia Scale (I-DOS) and to test its psychometric properties. Method A total sample of 422 volunteer university students (mean age = 20.70 ± 3.44, women 71.8%) completed a group of self-report questionnaires in large group sessions during their lecture time. The scales assessed ON (the I-DOS and the Orhto-15), disordered eating (Disordered Eating Questionnaire, DEQ), depressive symptoms (Beck Depression Inventory-II, BDI-II), obsessive and compulsive symptoms (Obsessive Compulsive Inventory-Revised, OCI-R), and self-reported height and weight.

Analyses confirmed the unidimensional structure of the I-DOS with acceptable or great fit indices (CFI = 0.984; TLI = 0.978; SRMR = 0.043; RMSEA = 0.076) and the strong internal consistency (α = 0.888). The correlations path supported the criterion validity of the scale. The estimated total prevalence of both ON and ON risk was 8.1%. Conclusions This 10-item scale appears to be a valid and reliable measure to assess orthorexic behaviors and attitudes. Level of evidence Level V, descriptive cross-sectional study.

To aid researchers in evaluating the construct validity of self-report imagery questionnaires in the context of their use as research instruments, standards are proposed for correlation coefficients under the headings of reliability, criterion validity, and content validity. Guidelines for deciding whether relationships are acceptable are also recommended.

Purpose This study provided reference data and examined psychometric properties for clausal density (CD; i.e., number of clauses per utterance) in children between ages 4 and 9 years from the database of the Edmonton Narrative Norms Instrument (ENNI). Method Participants in the ENNI database included 300 children with typical language (TL) and 77 children with language impairment (LI) between the ages of 4;0 (years;months) and 9;11. Narrative samples were collected using a story generation task, in which children were asked to tell stories based on six picture sequences. CD was computed from the narrative samples. The split-half reliability, concurrent criterion validity, and diagnostic accuracy were evaluated for CD by age. Results CD scores increased significantly between ages 4 and 9 years in children with TL and those with LI. Children with TL produced higher CD scores than those with LI at each age level. In addition, the correlation coefficients for the split-half reliability and concurrent criterion validity of CD scores were all significant at each age level, with the magnitude ranging from small to large. The diagnostic accuracy of CD scores, as revealed by sensitivity, specificity, and likelihood ratios, was poor. Conclusions The finding on diagnostic accuracy did not support the use of CD for identifying children with LI between ages 4 and 9 years. However, given the attested reliability and validity for CD, reference data of CD from the ENNI database can be used for evaluating children's difficulties with complex syntax and monitoring their change over time.

This study explored the associations between individuals presenting different problematic eating behaviors (Objective/Subjective binge-eating—OBE/SBE—and Compulsive/Non-compulsive grazing—C_Grazing/NC_Grazing) and eating disorder related symptoms. About 163 pre- and 131 post-bariatric patients were assessed. Assessment included: Face-to-face clinical interview to assess binge-eating and grazing episodes, and self-report measures to assess eating disorder symptomatology, psychological distress, and negative urgency. OBE and NC_Grazing were the problematic eating behaviors most and least associated with psychopathology, respectively. OBE and C_Grazing uniquely accounted for the significant variance in the most disordered eating variables. Our findings emphasize the need for the conceptualization of grazing behavior in the spectrum of disordered eating.

The purpose of the current study was threefold: a) to collect a very large representative sample of adolescents and assess for their levels of disordered eating behaviors; b) to describe the characteristics of adolescents with disordered eating behaviors in Cyprus based on the measures that were used in the study and c) to compare the adolescents with significant disordered eating behaviors (EAT-26 ≥ 20) to the ones without any disordered eating behaviors (EAT < 20) on all the variables of interest. A total of 2664 secondary school students responded to self-report measures assessing disordered eating, negative body image, situational dysphoria, self-esteem and media influences. Results indicated that 16.04% of the overall sample of adolescents scored significantly on the EAT-26 (21.4% of females and 8.4% of males). Results also indicated that the majority of the adolescents with disordered eating behaviors were female, mainly from average socioeconomic status, normal Body Mass Index and grew up and reside in an urban area. Finally, adolescents in the disordered eating behaviors group scored significantly lower on appearance satisfaction and self-esteem and significantly higher on appearance investment, weight-related anxiety, situational dysphoria, internalization of the thin and athletic ideals as well as feeling pressured from the media and considering the media as a good source of information. In conclusion, results indicate a substantial difference in levels of disordered eating in adolescents as compared to previous research in Cyprus. Possible explanations are addressed as well as implications for prevention strategies and future research ideas based on the findings.

Given the mixed conclusions on the psychometric properties of the Mindful Attention Awareness Scale (MAAS) and the variety of subsets of items identified as abbreviated forms, the current study aimed to (a) further investigate the performance of single items and different combinations of items of the MAAS from within an Item Response Theory framework, (b) to expand upon existing knowledge about the coverage of the construct of the scale and its shortened versions. A sample of 914 participants (67.6% women; mean age 23.28, SD = 4.77) completed the MAAS. To fulfill the second aim of the study, of the total sample, two subsamples ( N = 156 and N = 158, respectively) were administered a battery of self-report questionnaires. Analyses attested that four items of the MAAS have weak psychometric properties and that the reliability of the scale remains unchanged when these items are excluded. The relationships with several constructs (consciousness, present-time attitude, emotional intelligence, alexithymia, emotion regulation strategies, behavioral inhibition and activation, affect, anxiety, and depression) provided evidence that the scale adequately reflects the operationalization of the construct, although some facets of the construct are only partially covered. The current findings confirm that the MAAS might be slightly shortened without reducing its reliability and validity, but drastically abbreviated forms, such as the proposed five-item version, fail to maintain adequate psychometric properties.

ObjectiveThis study aimed to test the psychometric properties of the suicide stroop task in a Chinese college population.MethodsCollege students (n = 121) who were in the 1st–4th grade, fluent in Chinese, and without color blindness were recruited from a university in Guangzhou, China from September to December 2019. Participants were administered the suicide stroop task at baseline and 1-month follow-up.ResultsThe suicide stroop task showed excellent internal reliability (Cronbach’s α ranged from 0.940 to 0.953). However, the suicide stroop task did not reveal suicide-related attentional biases among current suicide ideators and was not significantly associated with the severity of suicidal ideation, depression, hopelessness, nor anhedonia (all p values &gt; 0.05), indicating a lack of concurrent validity for the task. Additionally, the two-time data of interference scores could not generate intraclass correlation coefficients (ICCs) due to a negative average covariance among data, which indicated poor test–retest consistency for the task.ConclusionThe results of this study did not support the use of the suicide stroop task on the identification of suicidal risk among Chinese college students. It is crucial to assess the psychometric properties of behavioral measures rigorously as self-report measures before large applications in clinical and community settings.

This article evaluates the psychometric properties of a new measure for assessing Substance-Related and Addictive Disorders: the Addictive Behavior Questionnaire (ABQ). The ABQ is a self-report measure composed of two sections: the Severity Index (SI) and the Seven Domains Addiction Scale (7DAS). Materials and methods. A total sample of 698 subjects divided into two groups (515 subjects in the clinical sample and 183 subjects in the control sample), participated in this study. We applied Exploratory Factor Analysis (EFA) to examine features of ABQ construct validity, we used Cronbach’s alpha coefficient to assess its internal reliability, and explored some aspects of its concurrent validity by examining its associations with other measures assessing addictive behaviors and psychopathology. Results and conclusions: results of EFA indicated that all the scales of the ABQ are unidimensional and showed good internal consistency. The correlations between the sections of the ABQ and the other measures used in the current study were significant and in the expected directions. These results suggest that the ABQ has good psychometric properties and allows researchers and clinicians to gather relevant information regarding behaviors, psychopathology and severity of symptoms, for the best clinical reasoning and for planning tailored treatment for each patient.

Using experience sampling methodology, we examined the effects of frequency and occurrence of appearance-based comparisons on disordered eating behaviors (binge eating, restrictive behaviors, and weight-related exercise). A total of 161 Australian women (aged 18–48) completed a baseline measure of eating pathology. An iPhone application prompted participants 6 times daily for 7 days to self-report on appearance comparisons and disordered eating behaviors since the last assessment. We hypothesized that contemporaneously reported occurrences of both upward and downward appearance comparisons, when compared to noncomparison situations, and frequency of upward comparisons would predict disordered eating behaviors. In prospective (lagged) analyses, only upward comparisons (relative to noncomparison situations) significantly predicted the likelihood of disordered eating outcomes. Trait eating pathology had a direct effect on each disordered eating variable and also moderated the influence of upward appearance comparisons (relative to noncomparison assessments) on binge-eating episodes. The lack of a differentiated effect between contemporaneously reported occurrences of upward and downward comparisons suggests that both forms of comparison increase the likelihood of disordered eating. Women may benefit from preventive programs that focus on the detrimental consequences of appearance comparisons on disordered eating; such programs may equip women with strategies to help reduce the frequency of these comparisons.

This study aims to develop and validate a new self-report questionnaire to measure orthorexia nervosa (ON). Based on a current review of the scientific literature and interviews with people at risk of orthorexia, 40 items were selected to test orthorexia nervosa (TON-40). A total sample of 767 individuals (M = 26.49, SD = 9.66, 56.98% women) participated in the study. The exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and composite construct analysis (CCA) were performed to find an appropriate model of sufficient reliability and validity and stable construction. Convergent validation was performed regarding the correlation of the TON-17 with another measure of ON (ORTO-15), eating disorders (the EAT-26 and DEAS), healthy behavior (the HBI), quality of life (the Brief WHOQOL), physical health (the GRSH), anxiety (the GAD-7), depression (the PHQ-9), and obsessive-compulsive disorder (the OCI-R). Gender, Body Mass Index (BMI), and the medical reasons for a restrictive diet were also examined. As a result of the structural analyses, the number of items was reduced from 40 to 17. The best fit indices of the TON-17 were found for the hierarchical bi-factor model, with three lower-order factors (Control of food quality, Fixation of health and healthy diet, and Disorder symptoms) and one general higher-order factor (Orthorexia). According to the 95th percentile method of estimation, the prevalence of ON was 5.5% for the TON-17 total score. The TON-17 scale and subscales showed good psychometric properties, stability, reliability, and construct validity. The TON-17 indicated a positive relationship with the ORTO-15, EAT-26, DEAS, HBI, OCI-R, GAD-7, and PHQ-9. TON-17 can be considered as a useful tool for assessing the risk of ON.
