Worries about possible harmful effects of new technologies (modern health worries) have intensely been investigated in the last decade. However, the comparability of translated self-report measures across countries is often problematic. This study aimed to overcome this problem by developing psychometrically sound brief versions of the widely used 25-item Modern Health Worries Scale (MHWS) suitable for multi-country use. Based on data of overall 5,176 individuals from four European countries (England, Germany, Hungary, Sweden), Ant Colony Optimization was used to identify the indicators that optimize model fit and measurement invariance across countries. Two scales were developed. A short (…

Short Form of the State-Trait Anger Expression Inventory-2

2020

Abstract. The purpose of the present study was to develop a short form of the State-Trait Anger Expression Inventory-2 (STAXI-2) based on the German STAXI-2. Item selection was performed based on exploratory factor analyses (EFA) using descriptive statistical parameters and content-related considerations on calibration samples ( N1 = 215, N2 = 310). The factorial structure of the final extracted scales was validated via confirmatory factor analyses (CFA) ( N3 = 216, N4 = 310). Overall, results present an economic and reliable questionnaire with a total length of 24 items: State Anger short scales Feeling Angry, Verbal Anger Impulse, and Physical Anger Impulse (3 items each), that can be ag…

Test Item Taxonomy Based on Functional Criteria

2018

There are many taxonomies that try to classify and apply some consistency to the very many item types currently in existence. They all have various limitations, however, such as ambiguous classification criteria, little discrimination between format types, and referring almost exclusively to pen-and-paper or screen-based items. This paper aims to overcome these limitations by proposing a new item format taxonomy based on functional criteria. Current classifications are reviewed, the criteria they are based on are examined and their limitations are identified. The proposed alternative classification identifies four essential components of items according to function: the structure of the included…

Validation of the Weight Bias Internalization Scale for Mainland Chinese Children and Adolescents

2021

Weight stigma internalization among adolescents across weight categories leads to adverse psychological consequences. This study aims to adapt and validate a Chinese version of the Weight Bias Internalization Scale for Mainland Chinese children and adolescents(C-WBIS). A total of 464 individuals aged 9 to 15 years participated in the present study. Based on item response theory (IRT) and classical test theory (CTT), we selected the items for the C-WBIS and evaluated its reliability and validity. The item response theory yields support for the one-dimensional factor mode. All item parameters fit the IRT model (albeit within an adequate range), eight items were adopted. No evidence of signifi…

Word classes and the scope of lexical flexibility in Tongan

2017

Abstract Tongan is an Oceanic language belonging to the Polynesian subgroup. Based on previous work (Churchward 1953, Tchekhoff 1981, Broschart 1997), Tongan has been classified as a 'flexible' language by various typological approaches on word classes (Hengeveld 1992, Rijkhoff 1998, Croft 2001). This means that lexical items are per se not categorised in terms of major word classes, but they can function as noun, verb, adjective and manner adverb without morphosyntactic derivation. However, not all lexemes are entirely flexible occurring within all these constructions. So the crucial issue of how flexible Tongan really is remains. This question will be addressed by a survey based on a comb…

Macular sensitivity and structure in idiopathic epiretinal membranes 12 months after surgical treatment

2013

Purpose: To evaluate macular sensitivity (MS) change and its correlation with visual acuity (VA) and Spectral-Domain Optical Coherence Tomography (SD-OCT) in patients with idiopathic epiretinal membrane (ERM) at 3, 6 and 12 months after surgical treatment.Methods: Prospective, monocenter, interventional case series. We included 49 patients (49 eyes) with an idiopathic ERM scheduled for a surgical treatment. Among these patients, 40 were evaluated at 3 and 6 months (M3, M6), and 31 at 12 months (M12) after ERM and internal limiting membrane removal. At each visit a measurement of best-corrected visual acuity (ETDRS), a microperimetry and a SD-OCT were performed for all patients.Results: The …

The WHO-5 Well-Being Index – Validation based on item response theory and the analysis of measurement invariance across 35 countries.

2020

Abstract Background The five-item World Health Organization Well-Being Index (WHO-5) is a frequently used brief standard measure in large-scale cross-cultural clinical studies. Despite its frequent use, some psychometric questions remain that concern the choice of an adequate item response theory (IRT) model, the evaluation of reliability at important cutoff points, and most importantly the assessment of measurement invariance across countries. Methods Data from the 6th European Working Condition survey (2015) were used that collected nationally representative samples of employed and self-employed individuals (N = 43,469) via computer-aided personal interviews across 35 European countries. …

Efficacy of an internet-based psychological intervention for problem gambling and gambling disorder: study protocol for a randomized controlled trial

2021

Gambling Disorder is a prevalent non-substance use disorder, which contrasts with the low number of people requesting treatment. Information and Communication Technologies (ICT) could help to enhance the dissemination of evidence-based treatments and considerably reduce the costs. The current study seeks to assess the efficacy of an online psychological intervention for people suffering from gambling problems in Spain. The proposed study will be a two-arm, parallel-group, randomized controlled trial. A total of 134 participants (problem and pathological gamblers) will be randomly allocated to a waiting list control group (N = 67) or an intervention group (N = 67). The intervention program i…

Using the Johnson-Neyman Procedure to Detect Item Bias in Personality Tests

2016

I present an alternative to a widely used item-bias analysis procedure known as the ANOVA method. The new method is based on the Johnson-Neyman procedure, which is a multiple regression-based technique with properties that can overcome the major weaknesses of the ANOVA method. I introduce the proposed procedure in a non-technical manner, provide an illustrative example, and suggest guidelines for empirical analysis that can be readily applied in personality research.

Evaluación de las actitudes de culpabilización de la víctima en casos de violencia de pareja contra la mujer: desarrollo y validación de la escala VB…

2018

ABSTRACT Intimate partner violence against women (IPVAW) is the most common form of violence suffered by women and constitutes a serious public health problem of global proportions. Public attitudes towards IPVAW are key to understanding the social context in which this type of violence occurs. Victim-blaming attitudes are among those that reflect public tolerance and acceptability of IPVAW and are often used to explain or justify IPVAW. In this study we develop and validate a new instrument to assess victim-blaming attitudes in cases of IPVAW. A sample of 1,800 participants was recruited through social media and a second sample of 50 IPVAW offenders was used for validation purposes. Throug…
