During the present decade a large body of research has employed confirmatory factor analysis (CFA) to evaluate the factor structure of the Strengths and Difficulties Questionnaire (SDQ) across multiple languages and cultures. However, because CFA can produce strongly biased estimations when the population cross-loadings differ meaningfully from zer...

Recent research points to the bidimensional nature of orthorexia, with one dimension related to interest in healthy eating (healthy orthorexia) and another dimension related to a pathological preoccupation with eating healthily (orthorexia nervosa). Research was needed to provide further support for this differentiation. We examined the food-choice...

Currently, there are two predominant approaches in adaptive testing. One, referred to as cognitive diagnosis computerized adaptive testing (CD-CAT), is based on cognitive diagnosis models, and the other, the traditional CAT, is based on item response theory. The present study evaluates the performance of two item selection rules (ISRs) originally d...

Background Orthorexia nervosa (OrNe) is a pattern of disordered eating behavior characterized by excessive preoccupation with overvalued ideas about healthy eating. Healthy orthorexia (HeOr) refers to a non-pathological interest in healthy eating and nutrition. Despite converging evidence that OrNe is correlated with measures of psychopathology and...

Intuitive eating is defined as an adaptive way of eating that maintains a strong connection with the internal physiological signs of hunger and satiety. It has four elements: unconditional permission to eat whenever and whatever food is desired, eating for physical rather than for emotional reasons, reliance on hunger and satiety cues to determine...

Background Compulsivity is the hallmark of addiction progression and, as a construct, has played an important role in unveiling the etiological pathways from learning mechanisms underlying addictive behavior to harms resulting from it. However, a sound use of the compulsivity construct in the field of behavioral addictions has been hindered to date...

This is a viewpoint that comments on a recent article by López-Gil et al. ("Overall proportion of orthorexia nervosa symptoms: a systematic review and meta-analysis including 30,476 individuals from 18 countries"), which is currently in press at the Journal of Global Health.

Background Compulsivity is the hallmark of addiction chronification and, as a construct, has played an important role in unveiling the etiological pathways from learning mechanisms underlying addictive behavior to harms resulting from it. However, a sound use of the compulsivity construct in the field of behavioral addictions has been hindered to d...

Purpose Orthorexia nervosa (OrNe) is a potentially pathological condition characterized by a fixation on healthy diet. An increasing number of studies have been conducted on this mental preoccupation, but the validity and reliability of some of the psychometric instruments employed in its assessment are still under debate. Among these measures, the...

As no French validated measurement tool distinguishing healthy orthorexia (HeOr) from orthorexia nervosa (OrNe) currently exists, this study aimed at examining psychometric properties of the French version of the Teruel Orthorexia Scale (TOS). A sample of 799 participants (Mean [SD] age: 28.5 [12.1] years-old) completed the French versions of the T...

Public toilets are a critical public health issue with a significant negative impact on people's lives. Unfortunately, the effect of negative experiences caused by public toilets on people's quality of life and life satisfaction is unknown. In this study, participants (n = 550) were asked to fill in a scale-based survey about their negative experie...

Consensual non-monogamy (CNM) is a non-normative relationship that can generally be defined as relationships in which the involved individuals have openly agreed that they can have other sexual and/or affective partners. Despite growing interest in CNM, little research has been conducted regarding characteristics of the involved individuals, as wel...

Purpose Since the term orthorexia nervosa (ON) was coined from the Greek (ὀρθός, right and ὄρεξις, appetite) in 1997 to describe an obsession with “correct” eating, it has been used worldwide without a consistent definition. Although multiple authors have proposed diagnostic criteria, and many theoretical papers have been published, no consensus de...

Background Psychometric properties of the Teruel Orthorexia Scale (TOS) have been examined in several languages (Arabic, English, Portuguese, Spanish, and Turkish), but not in French. Purpose The objective was to examine the psychometric properties of the TOS among a French-Canadian adult sample. Methods Participants were 296 French-speaking Cana...

Current research in attitudes towards the sexuality of adults with intellectual disabilities yields heterogeneous results. The aim of the present paper was to systematically review current qualitative and quantitative evidence of attitudes towards the sexuality of adults with intellectual disabilities. A systematic review of current literature (200...

Amidst a worldwide vaccination campaign, trust in science plays a significant role when addressing the COVID-19 pandemic. Given current concerns regarding research standards, we were interested in how Spanish scholars perceived COVID-19 research and the extent to which questionable research practices and potentially problematic academic incentives...

Little is known about orthorexia in both its pathological (orthorexia nervosa, OrNe) and adaptive (healthy orthorexia, HeOr) forms. To date, few studies have been carried out to analyze the personality profile associated with orthorexia, and the results have been contradictory. The aim of the present study was to explore the characteristic patholog...

Background: Some of the commonly used tools to assess orthorexia nervosa (OrNe) do not allow a meaningful interpretation of the scores or yield mixed results about the dimensions needed to represent orthorexia. Since no advancement in the theoretical knowledge can be made without a thorough examination of the measurement aspects, this study aimed t...

Knowledge of diverse sexual motivations can have profound implications for our comprehension of the causes, correlations, and consequences of sexual behavior. This study had two objectives: on the one hand, to determine the different motives why young Spanish university students have sex and their relationship with different sociodemographic and ps...

Because of its prevalence and its potential negative consequences, child sexual abuse (CSA) is a public health problem in every country in the world. Knowledge of the characteristics of abuse episodes (victim, abuser, relationship between them, type of sexual contact, duration, threat and/or use of force) is essential to specify the contents of int...

Counterproductive work behaviors (CWBs) refers to a set of negative intentional behaviors that harm organizational outcomes. Despite their consequences, their measurement is a debatable issue. The present study is aimed to validate the Spanish version of one of the most commonly used scales of CWBs, the Workplace Deviance Scale, and to provide furt...

In recent years, dating apps have changed the way people meet and communicate with potential romantic and/or sexual partners. There exists a stereotype considering that these apps are used only for casual sex, so those apps would not be an adequate resource to find a long-term relationship. The objective of this study was to analyze possible indivi...

Tinder is the most popular and most used dating app in the world today. Due to the recent popularization of the phenomenon of dating apps, there are still some gaps in the literature. Therefore, this study had a threefold objective: (1) to determine the prevalence and characteristics of Tinder users and Tinder use among young university students; (...

Public bathrooms are sensible locations in which individuals confront an intimate environment outside the comfort of their own home. The assessment of public bathrooms is especially problematic for people whose illnesses make them more prone to needing this service. Unfortunately, there is a lack in the evaluation of the elements that are relevant...

The emergence and popularization of dating apps have changed the way people meet and interact with potential romantic and sexual partners. In parallel with the increased use of these applications, a remarkable scientific literature has developed. However, due to the recency of the phenomenon, some gaps in the existing research can be expected. Ther...

The development of new technologies, the expansion of the Internet, and the emergence of dating apps (e.g., Tinder, Grindr) in recent years have changed the way to meet and approach potential romantic and/or sexual partners. The recent phenomenon has led to some gaps in the literature on individual differences (sociodemographic variables and person...

We respond to some of Myszkowski and colleagues’ (2020, Br. J. Psychology) criticalcomments on our recent work on aesthetic sensitivity (Corradi, Chuquichambi, Barrada,Clemente, & Nadal, 2020, Br. J. Psychology). We show that these comments stem mostlyfrom factual inaccuracies.

The purposes of this research were: (1) to analyse the psychometric properties of the Inferential Confusion Questionnaire‐Expanded Version (ICQ‐EV) in a Spanish population; (2) to explore the role of inferential confusion in obsessive‐compulsive disorder (OCD); and (3) to compare the inferential confusion construct in non‐clinical and clinical samp...

The turbulent context in which organizations operate today makes them search for adaptable workers. Previous studies have shown the predictive value of the "Big Five" personality traits on adaptive performance, but some authors suggest extending personality domain with the "dark" traits of personality, that is, Machiavellianism, narcissism, psychop...

Aesthetic sensitivity has been defined as the ability to recognize and appreciate beauty and compositional excellence, and to judge artistic merit according to standards of aesthetic value. The Visual Aesthetic Sensitivity Test (VAST) has often been used to assess this ability, but recent research has revealed it has several psychometric problems....

This study analyzed incremental effects of the Dark Tetrad traits (i.e., narcissism, Machiavellianism, psycho-pathy, sadism) on job performance dimensions (i.e., task performance, contextual performance, counter-productive work behavior) over the Big Five and Honesty-Humility. Using a multi-occupational sample of 613 employees, results revealed pos...

Job performance is considered the “ultimate dependent variable” in human resource management, turning its assessment into a capital issue. The present study analyzes the functioning of a brief 18-item self-report scale, the Individual Work Performance Questionnaire (IWPQ), which measures the main dimensions of job performance (task performance, con...

Childhood sexual abuse (CSA) is considered as an activity aimed at providing sexual pleasure, stimulation, or sexual gratification to an adult who uses a minor for this purpose, taking advantage of the situation of superiority. CSA can have devastating consequences for the child. Previous studies have concluded that those who suffer an episode of C...

Research about sociosexuality, understood as differences in people’s willingness to have sex without commitment in terms of its predictors, such as demographics, relationship status, or individual traits, such as personality, is still scarce. Although sociosexuality was initially considered unidimensional, a tridimensional structure—with behavior,...

It was recently proposed that healthy orthorexia (HeOr) and orthorexia nervosa (OrNe) should be differentiated. The aim of the present study was to analyze whether the two dimensions of orthorexia can be considered new eating styles or basically equivalent to restrained eating behavior. Two samples of university students (sample 1, n = 460; sample...

Rationale and method Accurately identifying motives to gamble is crucial in the functional analysis of gambling behavior. In this study, a data-driven approach was followed to clarify the factor structure underlying a pool of motives for gambling, selected from the Gambling Motives Questionnaire–Financial (GMQ-F), and the Reasons for Gambling Quest...

Young people's use and participation in online sexual activities (OSA) has increased in the past two decades and has changed their behavior in the area of sexuality. The existing literature has some important limitations, concerning the assessment of the construct and its orientation toward problematic use, while ignoring its healthy use or social...

This study analyses the extent to which cheating occurs in a real selection setting. A two-stage, unproctored and proctored, test administration was considered. Test score inconsistencies were concluded by applying a verification test (Guo and Drasgow Z-test). An initial simulation study showed that the Z-test has adequate Type I error and power ra...

Orthorexia nervosa could be conceptualized as extreme or excessive preoccupation with eating food believed to be healthy. Orthorexia nervosa and healthy orthorexia (interest in healthy eating) can be distinguised. Up to now, there is no available instrument evaluating every aspect of orthorexia with sufficient psychometric guarantees. The objective...

Background: Earlier scales on mindful eating do not measure mindful eating independent from emotional or external eating, or mindful eating in common situations. Objective: The objective was to develop a new instrument to measure the attention element of mindful eating, the Mindful Eating Behavior Scale (MEBS), and to compute the internal struct...

Casual sex has become a common experience for many university students. Therefore, it is necessary to have instruments and studies that analyze youth's orientation towards sociosexuality. The SOI-R assesses sociosexual behavior, attitudes towards sociosexuality, and the desire for relationships without commitment with just nine items. The goal of t...

Casual sexual relations, understood as those in which there are no expectations of affective commitment, are increasingly common among youth. The goal of this study was to analyze the casual sexual behavior of students from a Spanish university, paying special attention to its relation with sociodemographic and psychosexual variables. Participants...

Orthorexia nervosa has recently been defined as excessive preoccupation with healthy eating, causing significant nutritional deficiencies and social and personal impairments. The ORTO-15 is the most widely used instrument to evaluate orthorexia nervosa, although previous studies obtained inconsistent results about its psychometric properties, and t...

Stereotype dimensions—competence, morality and sociability—are fundamental to studying the perception of other groups. These dimensions have shown moderate/high positive correlations with each other that do not reflect the theoretical expectations. The explanation for this (e.g., halo effect) undervalues the utility of the shared variance identifie...

Objective: The IDEAL Schedule was developed for staging "care needs" in patients with dementia. We here aim to validate the Spanish version, further test its psychometric properties and explore a latent construct for "care needs". Methods: A multicenter study was done in 8 dementia care facilities across Spain. Patients referred with a reliable...

Background: Even though the Five Factor Model (FFM) has been the dominant paradigm in personality research for the past two decades, very few studies have measured the FFM adaptively. Thus, the purpose of this research was the building of a new item pool to develop a computerized adaptive test (CAT) for personality assessment. Method: A pool of...

Research related to the fit evaluation at the item level involving cognitive diagnosis models (CDMs) has been scarce. According to the parsimony principle, balancing goodness of fit against model complexity is necessary. General CDMs require a larger sample size to be estimated reliably, and can lead to worse attribute classification accuracy than...

The current study proposes a new bi-factor rotation method, Schmid-Leiman with iterative target rotation (SLi), based on the iteration of partially specified target matrices and an initial target constructed from a Schmid-Leiman (SL) orthogonalization. SLi was expected to ameliorate some of the limitations of the previously presented SL bi-factor r...

The purpose of this paper is to list the recent updates of the R package catR. This package allows for generating response patterns under a computerized adaptive testing (CAT) framework with underlying item response theory (IRT) models. Among the most important updates, well-known polytomous IRT models are now supported by catR; several item select...

Perceived control has shown predictive value for anxiety severity symptoms as well as cognitive-behavior therapy outcomes. The most commonly used measure of perceived control is the Anxiety Control Questionnaire (ACQ), and more recently the ACQ Revised (ACQ-R). However, both questionnaires have shown structural inconsistencies among several studies...

Background: We studied herein the predictive value for panic severity of three well-based vulnerability factors: personality traits (neuroticism and extraversion; NEO-PI-R), anxiety sensitivity (ASI), and perceived control (ACQ-R). Method: The sample was composed of 52 participants diagnosed with panic disorder, with or without agoraphobia, acco...

The Dutch Eating Behavior Questionnaire (DEBQ) is a widely used instrument for assessment of emotional, external, and restrained eating. Aim of the present study is to (1) analyze its internal structure using exploratory structural equation modeling, (2) to assess its measurement invariance with respect to sex, BMI, age, and level of education, and...

This article introduces two new item selection methods, the modified posterior-weighted Kullback-Leibler index (MPWKL) and the generalized deterministic inputs, noisy “and” gate (G-DINA) model discrimination index (GDI), that can be used in cognitive diagnosis computerized adaptive testing. The efficiency of the new methods is compared with the pos...

Test security can be a major problem in computerized adaptive testing, as examinees can share information about the items they receive. Of the different item selection rules proposed to alleviate this risk, stratified methods are among those that have received most attention. In these methods, only low discriminative items can be presented at the b...

The dimensionality of the Hospital Anxiety and Depression Scale (HADS) is a current source of controversy among experts. The present study integrates a solid theoretical framework (Clark & Watson's, 1991, tripartite theory) and a fine-grained methodological approach (structural equation modeling; SEM) to examine the dimensionality and construct val...

Background: No studies have been found that compared the psychopathology features, including personality disorders, of Panic Disorder (PD) and Panic Disorder with Agoraphobia (PDA), and a nonclinical sample with anxiety vulnerability. Method: The total sample included 152 participants, 52 in the PD/PDA, 45 in the high anxiety sensitivity (AS) sa...

Previous research has suggested multiple factor structures for the 12-item General Health Questionnaire (GHQ-12), with contradictory evidence arising across different studies on the validity of these models. In the present research, it was hypothesized that these inconsistent findings were due to the interaction of 3 main methodological factors: am...

In computerized adaptive testing pretest items are presented in conjunction with operational items to renew the item bank. Pretest items are calibrated, and possible differential item functioning (DIF) is analyzed. Some difficulties arise due to the large amount of missing responses, which can be avoided by the use of fixed item parameter calibrati...

Se estudiaron las diferencias psicopatológicas y de personalidad entre una muestra clínica, 52 pacientes con trastorno de pánico (TP) con agorafobia (TPA) o sin agorafobia y dos muestras no clínicas, una con 45 participantes con alta sensibilidad a la ansiedad (SA) y otra con 55 participantes con baja SA. La muestra clínica fue evaluada siguiendo c...

The prevention of eating disorders and disordered eating are increasingly recognized as public health priorities. Challenges in this field included moving from efficacy to effectiveness and developing an integrated approach to the prevention of a broad spectrum of eating and weight-related problems. A previous efficacy trial indicated that a univer...

Introduction: The main objective of this study was to develop and validate a new olfactory measure that assesses the influence of olfaction on several emotional, behavioural, and cognitive issues: The Relational Scale of Olfaction (EROL). A secondary objective was to explore the relationship between the olfactory function and the anxiety and depre...

The presentation of a hand grasp facilitates the recognition of subsequent objects when the grasp is coherent with the object to be identified. This outcome is usually explained as the integration of two different processes: descriptive visual processes in ventral visual areas and processes in charge of the computations of action metrics in dorsal...
