VII: Diagnosestudien: Einfache Maße für Validität und Reliabilität
2003
The evaluation of a new diagnostic or imaging device has to focus both on its diagnostic validity and reliability. Cohen's kappa coefficient can be used to assess the agreement of the new device's findings with those of an established diagnostic reference, it therefore presents a surrogate measure of validity. Additional measures of validity are sensitivity and specificity, which assess the order of agreement with the reference for positive and negative reference findings, respectively. The latter, however, can only be applied for binary reference findings. If discordant findings are observed, the McNemar test can be used to detect a diagnostic shift between diagnostic novum and reference. …
Validierung der Messung gesundheitsbezogener Lebensqualität mittels des Short-Form-Health-Survey-12 (SF-12 Version 2.0) in einer deutschen Normstichp…

Validation of the Short-Form-Health-Survey-12 (SF-12 Version 2.0) assessing health-related quality of life in a normative German sample Objectives: Convergent and divergent validation of the Short-Form-Health-Survey-12 assessing HRQoL by analyzing its associations with depressiveness (PHQ-9), social support (OSS-3) and satisfaction with life (SWLS). Methods: A normative German sample (N = 2.524) was analyzed using correlation, regression as well as confirmatory factor analysis and structural equation modelling for ordinal data. Results: The SF-12-scale Mental Health is associated most strongly with the validation criteria (PHQ: r[scales/constructs] = -.73/-.88, OSS-3: r = .35/.55, SWLS: r =…
Study Approaches in Higher Education Mathematics : Investigating the Statistical Behaviour of an Instrument Translated into Norwegian

Intellectual capital, organisational performance and competitive advantage
2019
At present, the role of intellectual capital in organisations is significantly more important than in the past owing to the transition from an economy based on assets to another based on knowledge. The value of intangible assets increases as that of tangible assets decreases; this allows organisations, which prioritise intellectual capital, to produce competitive advantages and achieve better performance. The purpose of this paper is to ascertain if human capital, structural capital and relational capital have a positive influence on the organisational performance of medium-sized firms in the Mexican manufacturing sector. Moreover, it is analysed if competitive advantage mediates the relati…
The Work Design Questionnaire: Spanish version and validation
2015
The purpose of this study is to validate the Spanish version of the Work Design Questionnaire (WDQ; Morgeson & Humphrey, 2006). Employees from three Colombian samples completed the questionnaire (N = 831). Confirmatory factor analyses revealed a 21-factor structure ( 2 /df ratio = 2.40, SRMR = .06, RMSEA = .04, CFI = .90) with adequate levels of convergent and discriminant validity. Additional support for construct validity was found from significant differences among different occupational groups (professional and nonprofessional, health-focused, commercial, and manufacturing workers). Furthermore, knowledge, social, and work context characteristics showed incremental validity over tas…
The Italian Version of the Career Factors Inventory
2015
This study attempted to examine the validity of the Italian version of the Career Factors Inventory (CFI), a psychometric tool widely used in the assessment of cognitive and personal–emotional dimensions of career indecision, among a sample of 2,060 Italian students attending high school and university. Recurring to both exploratory and confirmatory factor analyses, the original four-factor structure was confirmed and returned, in line with the literature, satisfactory reliability indices; moreover, CFI subscales showed intercorrelations consistent with previous studies, albeit lower in some cases. Subsequently, convergent validity between the four CFI subscales and other scales via zero-o…
L’attenzione per il benessere organizzativo nella Pubblica Amministrazione italiana. Analisi critica del questionario CIVIT/ANAC
2018
L'articolo propone una riflessione sugli studi inerenti al benessere organizzativo nel nostro Paese, e un'analisi secondaria sul questionario per la valutazione del Benessere organizzativo nella pubblica amministrazione italiana CIVIT/ANAC realizzata tra il personale tecnico amministrativo di alcuni atenei italiani, con tre obiettivi: confrontare le dimensioni del benessere incluse nel questionario con i fattori considerati nei più noti modelli che in letteratura hanno definito il costrutto del benessere al lavoro; controllare attendibilità e validità dello strumento; identificare la struttura semantica soggiacente alle risposte, prescindendo dall'impostazione precostituita del questionario.
The Spanish validation of the Short Health Anxiety Inventory: Psychometric properties and clinical utility
2019
The Short Health Anxiety Inventory (SHAI) is a widely used self-report instrument to evaluate health anxiety. To assess the SHAI's factor structure, psychometric properties, and accuracy in differentiating Spanish non-clinical individuals from patients with severe health anxiety or hypochondriasis.A total of 342 community participants (61.6% women;The original two-factor structure was selected as the best structure, based on its parsimony and empirical support (Factor 1: Illness likelihood; Factor 2: Negative consequences of illness). Moreover, the Spanish version of the SHAI demonstrated good construct and concurrent and discriminant validity, and internal consistency. A cutoff of 40.5 (to…
Influence of clinical and psychological variables upon the oral health-related quality of life in patients with temporomandibular disorders
2017
Background To analyze the association between the OHIP-14 and the different subtypes making up the clinical and psychological axis obtained using the RDC/TMD. Material and Methods 407 patients treated at the TMD unit of the Andalusian Healthcare Service were administered the Spanish version of the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire (RDC/TMD), together with the Oral Health Impact Profile questionnaire (OHIP-14). The degree of association between the patients’ score in the OHIP-14 and the clinical and biopsychosocial variables was analyzed through bivariate and multivariate analyses, specifically through linear regression. Results 89.4% of the treated p…
The Positive Personality Model (PPM): Exploring a New Conceptual Framework for Personality Assessment.
2018
The aim of this paper is to explore a new framework for personality assessment that may function as sanity nosology of personality traits: the Positive Personality Model. The recent publication of DSM-5 created the opportunity to assess personality traits as dimensional constructs (American Psychiatric Association, 2013). In Section III, five maladaptive personality traits are proposed as the maladaptive versions of Five Factor Model (FFM) traits (Costa and McCrae, 1985). This approach draws on the existing idea of conceptualizing pathological and typical personality traits as part of a continuum. It places DSM-5’s maladaptive traits in a sickness pole and FFM’s traits in a “typical” pole. …
