The content validity of the adult attachment interview. An empirical investigation using text analysis
2011
The aim of this study was to conduct a preliminary investigation of the content validity of the Adult Attachment Interview (AAI). Content validity is a series of hypothesis control methods relating to the communication of facts and it can be tested using several procedures of analytical decomposition (Rositi, 1988). In order to evaluate the content validity of a text, Sireci (1998), Sireci and Geisinger (1992, 1995), and Ding (2005) suggested the integration within this technique of multidimensional scaling and cluster analysis. The aim of this study was to conduct a preliminary investigation of the content validity of the AAI, as proposed in the literature. We hypothesized that participant…
Assessing first-year engineering students' pre-university mathematics knowledge: preliminary validity results based on an item response theory model
2020
The importance of students’ prior knowledge to their current learning outcomes cannot be overemphasised. Students with adequate prior knowledge are better prepared for the current learning materials than those without the knowledge. However, assessment of engineering students' prior mathematics knowledge has been beset with a lack of uniformity in measuring instruments and inadequate validity studies. This study attempts to provide evidence of validity and reliability of a Norwegian national test of prior mathematics knowledge using an explanatory sequential mixed-methods approach. This approach involves use of an item response theory model followed by cognitive interviews of some students …
Reliability and concurrent validity of the Velowin optoelectronic system to measure movement velocity during the free-weight back squat
2018
The objective of this study was to explore the reliability and concurrent validity of the Velowin optoelectronic system to measure movement velocity during the free-weight back squat exercise. Thirty-one men (age = 27.5 ± 3.2 years; body height = 1.76 ± 0.15 m; body mass: 78.3 ± 7.6 kg) were evaluated in a single session against five different loads (20, 40, 50, 60 and 70 kg) and three velocity variables (mean velocity, mean propulsive velocity and maximum velocity) were recorded simultaneously by a linear velocity transducer (T-Force; gold-standard) and a camera-based optoelectronic system (Velowin). The main findings revealed that (1) the three velocity variables were determined with a h…
Validation of the Five-Factor Self-Concept Questionnaire AF5 in Brazil: Testing factor structure and measurement invariance across language (Brazilia…
2018
Self-concept is widely conceptualized as multidimensional (Shavelson et al., 1976). The Five-Factor Self-Concept Questionnaire (AF5, Garcia and Musitu, 2009) assesses five specific dimensions (i.e., academic, social, emotional, family, and physical). It is a psychometrically sound questionnaire, developed, and normed in Spain, which is widely used with Spanish-speaking samples. The validation of the AF5 in Brazil would expand its potential, and would facilitate cross-cultural research. To validate the Brazilian version of the AF5, the present study apply confirmatory factor analysis and multi-sample invariance analysis across sex (women vs. men), age (11-18 years old), and language (Brazili…
International validation of the revised European Organisation for Research and treatment of cancer head and neck cancer module, the EORTC QLQ-HN43
2019
Background: We validated the new European Organisation for Research and Treatment of Cancer Quality of Life Head and Neck Module (EORTC QLQ-HN43). Methods: We enrolled 812 patients with head and neck cancer from 18 countries. Group 1 completed the questionnaire before therapy, and 3 and 6 months later. In group 2 (survivors), we determined test–retest reliability using intraclass correlation coefficients (ICC). Internal consistency was assessed using Cronbach's Alpha, the scale structure with confirmatory factor analysis, and discriminant validity with known-group comparisons. Results: Cronbach's alpha was >0.70 in 10 of the 12 multi-item scales. All standardized factor loadings exceeded…
Identidad deportiva en adolescentes españoles: propiedades psicométricas de la versión en español de la escala Athletic Identity Measurement Scale-E
2016
ResumenEste estudio pretende determinar las propiedades psicométricas de la Athletic Identity Measurement Scale en su versión traducida al español y la identidad deportiva (ID) de una muestra de adolescentes españoles. El cuestionario se administró a 441 adolescentes de 12-18 años, clasificados en: adolescentes del Programa de Especialización Deportiva (PED), adolescentes no-PED activos y adolescentes no-PED inactivos. El análisis factorial confirmatorio reveló una estructura jerárquica y multidimensional de tres factores de primer orden (identidad social, exclusividad y afectividad negativa) y uno de segundo orden, la ID. Los resultados apoyan la adecuación de los ítems en sus respectivas …
Diagnostic Validity of Digital Imaging Fiber-Optic Transillumination (DIFOTI) and Near-Infrared Light Transillumination (NILT) for Caries in Dentine.
2020
The objective of the study is to analyse the available evidence for the validity of the transillumination method in the diagnosis of interproximal caries. Bibliographic searches were carried out in three data bases (PubMed, Embase, Scopus) with the key words “Transillumination AND caries”. A total of 11 studies were selected for the qualitative analysis and meta-analysis. In the qualitative analysis, both in vivo and in vitro studies were included. The gold standards were tomography, digital radiography, and clinical visual diagnosis. The meta-analysis determined the sensitivity, specificity, and area below the ROC curve relative to the transillumination method in the diagnosis …
CP-violating Higgs boson production in association with three jets via gluon fusion
2014
In these proceedings, we present results for Higgs production at the LHC via gluon fusion with triple real emission corrections and the validity range of the heavy-top effective theory approximation for this process. For a general CP-violating Higgs boson, we show that bottom-quark loop corrections in combination with large values of $\tan \beta $ significantly distort differential distributions.
Validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese office workers.
2020
Abstract Background As sedentary behavior is a global health issue, there is a need for methods of self-reported sitting assessment. The accuracy and reliability of these methods should also be tested in various populations and different cultural contexts. This study examined the validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese subgroups. Methods Two cohort groups of office-based workers (58.6% female, age range 22–67 years) participated: a Finnish group (FIN, n = 34) and a Chinese group (CHI, n = 36). Long-term (past 3-month sitting) and short-term (daily sitting assessed on 5 consecutive days) single-item measures were used to assess self-r…
Evaluation of Treatment Integrity: The Treatment Specificity Index
2015
Objective To differentiate between treatments in a randomized controlled trial (RCT), therapies need to display not only high purity but also high specificity. The aim of this study was to demonstrate the benefits of calculating a treatment specificity index for the evaluation of treatment differentiation. Method Based on an RCT of relapse prevention in depression, comparing a cognitive with a psychoeducational treatment, the specificity and the purity index were calculated. Results As indicated by the specificity index, both conditions differed in their levels of implemented specific and common interventions. A significant relationship was found between symptom change before a therapy sess…
