Dimensionality of depression in acute schizophrenia: a methodological study using the Bech-Rafaelsen Melancholia Scale (BRMES).
1998
Abstract Despite the great clinical importance of depressive symptoms in schizophrenia there is a lack of studies on the assessment and evaluation of depression in acutely psychotic patients. For the Bech-Rafaelsen Melancholia Scale (BRMES), among other advantages, the concept of unidimensionality was confirmed in patients with major depression by different methodological approaches including Rasch analysis. The present evaluation was designed to investigate the scale properties of the BRMES in acutely schizophrenic patients with particular emphasis on the dimensionality of the scale. Three different statistical approaches were used: principal component analysis in combination with computer…
Organizational learning: Proposal of an integrative scale and research instrument
2014
Abstract This study describes the development and validation of an instrument to measure organizational learning. Starting out from a comprehensive analysis of the main organizational learning models in the specialized literature, the organizational learning scale in this study consists of 18 items forming five dimensions: the ontological levels of learning, modes of knowledge conversion, learning sub-processes, types of learning, and feedback and feed-forward flows of learning. A survey to large Spanish companies provides data from 167 companies. Confirmatory factor analysis tests the construct measurement model and validates the scale. The results of the study indicate that the scale sati…
<p>Translation, validation, and cross-cultural adaptation of the Polish version of the pain sensitivity questionnaire</p>
2019
Introduction The purpose of this study was to provide a translation, cross-cultural adaptation, and validation of the Polish language version of the pain sensitivity questionnaire (PSQ). The process followed widely accepted guidelines. Methods The translated questionnaire underwent thorough psychometric testing. In total, the data of 144 subjects (mean age 52.53±13 years), who underwent evaluation for lower back pain, were included. Results The exploratory factor analysis revealed a two-factor structure, PSQ-moderate and PSQ-minor. The internal consistency was good (Cronbach's α was 0.96). There was a fair and significant correlation between the results of the PSQ and the coping strategy qu…
The Structure and Stability of Perceived Togetherness in Elderly People during a 5-Year Follow-Up
2004
The objective of this study was to study the structure andstability of perceived togetherness using cross-sectional and longitudinal confirmatory factor analysis models. Togetherness was measured with the self-administered Social Provision Scale (SPS). The sample consisted of 111 persons interviewed in connection with the Evergreen project’s 5-year follow-up at ages 80 and 85. One and two-factormodels were specified separately at two different pointsof measurement. The stability of the factor models’ structure and the level of latent factors was studied using longitudinal factor analysis models. The two-factor model fit the data better than the one-factor model. Perceived togetherness was …
Smartphone Addiction Inventory (SPAI): Psychometric properties and confirmatory factor analysis
2016
The Smartphone Addiction Inventory (SPAI) was developed to assess smartphone addiction in Taiwanese university students. The purpose of the current research is to evaluate the factor structure and psychometric properties of the SPAI in Italian university students. A total of 485 university students (29.3% boys) completed the SPAI and the Young's Internet Addiction Test (IAT).The proposed four-factor model of the SPAI-I was tested by computing CFA, and the results of the goodness of fit indices indicated an ambiguous solution. An exploratory-confirmatory cross validation strategy was applied for a better trimming of SPAI-I factorial structure. Results suggested a five-factor solution that ex…
Development and psychometric properties of an instrument for the Assessment of Sexual Behaviour and Knowledge of people with Intellectual Disability
2020
Background This paper presents psychometric properties of an instrument for the Assessment of Sexual Behaviour and Knowledge of people with Intellectual Disability (ASBKID), other‐reported by professionals who are in daily contact with them. Methods and procedures Assessments of 236 individuals with intellectual disability were obtained from 100 professionals. Results Confirmatory factor analysis revealed a four‐factor structure: concern about the user's inappropriate or uninhibited sexual behaviour; perception of the user's knowledge about privacy and social norms; perception of the user's knowledge about sexuality; and concerns about the user's sexuality. A multi‐group CFA was also conduc…
Construction and Validation of a Self-Efficacy Scale for Latex Barrier Use.
2016
AbstractSome studies have concluded there is a relationship between perceived self-efficacy and behaviors that prevent HIV transmission. This paper presents the construction and validation of the latex barrier use self-efficacy scale (LBSS), which 480 participants filled out. Exploratory factor analysis yielded two components: positive expectations of self-efficacy (ES-POS) and negative expectations of self-efficacy (ES-NEG), which together accounted for 65.59% of total variance. That structure was later verified through confirmatory factor analysis. Internal consistency was .80 for the total scale, and .78 for each of the two factors. Moreover, the instrument had adequate convergent validi…
The Reciprocal Influences among Motivation, Personality Traits, and Game Habits for Playing Pokémon GO
2018
This article reports a study exploring motivations of Pokémon Game use, individual differences related to personality traits, and game habits. First, it analyzed Pokémon GO motivations through exploratory factor analysis (EFA) by administering online the Pokémon GO Motivational Scale to a group of Italian gamers (N = 560). Successively, a Confirmatory Factor Analysis (CFA) was conducted testing three factorial models of Pokémon Game motivations on a selected random sample (N = 310). Results showed a three-factor model of Pokémon GO Game motivations (i.e. Personal Needs, Social Needs and Recreation), accounting for 68.9% of total variance plus a general higher order factor that best fits the…
Testing invariance between web and paper students satisfaction surveys. A case study
2017
[EN] Purpose: This paper studied the measurement invariance (MI) across web-based and paper-based surveys to evidence if both techniques of data collection can be regarded as equivalent. Design/methodology: We develop a multigroup confirmatory factor analysis (MGCFA) with Maximum Likelihood Estimation to asses measurement invariance of the Job Diagnostic Survey (JDS) adapted to teaching, with data collected from paper and web surveys. Sample from paper surveys was constituted by 294 student of a Spanish public university in the academic years 2007-08, 2008-09 and 2009-10. Internet surveys were administered through an open source survey application called Lime Survey. We received 241 complet…
The SCIA Questionnaire: standards for communities for children and adolescents – a tool for the evaluation of good practices
2019
Purpose The purpose of this paper is to present the Italian validation of the standards for communities for children and adolescents (SCIA) Questionnaire, an evaluation tool of communities quality standards, based on the “Service Standards for Therapeutic Communities for Children and Young People – 2nd edition” of the Community of Communities (2009), that enables an empirical, multidimensional and complex evaluation of the therapeutic community (TC) “system”. It is a self-report that sets out and measures variables that allow to get an overview of organisational models and the possible development areas to improve the effectiveness of the protection of child and adolescents in community tr…
