Reliability and validity of the Toronto Structured Interview for Alexithymia in a mixed clinical and nonclinical sample from Italy
2011
The reliability and validity of the Toronto Structured Interview for Alexithymia (TSIA) have been demonstrated in previous studies with English-speaking community and psychiatric samples and a German-speaking psychiatric sample. The aim of this study was to evaluate the psychometric properties of the TSIA in a mixed clinical and nonclinical sample from Italy. The original English version of the TSIA was translated into Italian and administered, along with the 20-item Toronto Alexithymia Scale (TAS-20), to 80 healthy subjects, 69 medical outpatients, and 62 psychiatric outpatients. Eighty-one videotaped interviews were used for assessing the interrater reliability. Confirmatory factor analys…
Work-home interaction from a work psychological perspective: Development and validation of a new questionnaire, the SWING
2005
Contains fulltext : 54536.pdf (Publisher’s version ) (Closed access) This paper reports on the stepwise development of a new questionnaire for measuring work-home interaction, i.e. the Survey Work-home Interaction—NijmeGen, the SWING). Inspired by insights from work psychology, more specifically from Effort-Recovery Theory (Meijman & Mulder, 1998), we defined work-home interaction by differentiating between the direction and quality of influence. Four types of work-home interaction were distinguished and measured by using 22 (including 13 self-developed) items. By using data from five independent samples (total N=2472), validity evidence was provided based on the internal structure of the q…
Perceived Vulnerability to Disease Questionnaire: Factor structure, psychometric properties and gender differences
2016
Abstract The evolutionary psychological approach links evolved mechanisms of disease-avoidance to prejudices against individuals perceived as a threat to health. Perceived vulnerability to disease works as an adaptive strategy which explains why individuals perceived as a source of contagion are avoided. The self-report Perceived Vulnerability to Disease Questionnaire, PVDQ, is one of the most widely used to measure subjective vulnerability to disease, however, neither test–retest reliability has been studied nor has factor structure been confirmed so far in this questionnaire. In the present study, a sample of 878 participants completed the PVDQ. Subsamples also completed different scales …
Longitudinal factor analysis models in the assessment of the stability of sense of coherence
2000
The present study examined the stability of sense of coherence using longitudinal factor analysis models. Sense of coherence was measured by Antonovsky’s [Antonovsky, A. (1987a). Unraveling the mystery of health. How people manage stress and stay well. San Francisco: Jossey-Bass.] short-form (13-item) Orientation to Life Questionnaire (OLQ). Analyses were carried out using one-year follow-up data consisting of 219 Finnish employees working in four organizations. A three-step analytic procedure was used. First, a one-factor, a three-factor, and a second-order factor model were specified and compared separately in two measurements. Second, the stability of the constructs in the three alternat…
Psychometric Evaluation of the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) in Italy
2017
The purpose of this multistudy report was to adapt the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) to the Italian context. Two studies were conducted. In Study 1, we investigated the dimensionality, reliability, and convergent and discriminant validity of the instrument in a sample of 544 participants (males = 41%) from 16 to 35 years old. In Study 2, we replicated the results concerning dimensionality in an independent sample of 502 participants (males = 42%) from 16 to 35 years old. Furthermore, we analyzed measurement invariance across gender. Results of both studies showed that comparing a series of competitive factorial models, the 6-factor model had the best f…
Factorial Validity and Reliability of the Curricular Goals in Physical Education Questionnaire
2015
This study aimed to examine the validity and reliability of an instrument designed to measure student perceptions of curricular goals in physical education, the Curricular Goals in Physical Education Questionnaire. Participants were 879 Finnish students from grades 7 to 9 (412 girls, 467 boys; mean age 13.81). An exploratory factor analysis was performed on Sample 1 (n = 287), revealing a four-factor solution and suggesting that factor structure be cross-validated with confirmatory factor analysis in Sample 2 (n = 592). Confirmatory factor analysis demonstrated an acceptable fit and supported the four-factor model. Tests for gender invariance supported configural, metric, and scalar invaria…
Factor Structure and Construct Validity of the Youth Psychopathic Traits Inventory and Its Shorten Version in Chinese Detained Boys
2019
The Youth Psychopathic Traits Inventory (YPI) was designed to assess psychopathic traits in adolescents. However, there exists limited evidence for the factor structure and psychometric properties of the YPI when used with Chinese detained juveniles. The present study aimed to examine the factor structure and construct validity of the YPI and its shortened version (YPI-S) in a sample of 607 Chinese 14- to 22-year-old detained boys (M = 17.15, SD = 1.09). Confirmatory factor analyses revealed a bifactor model which best fit the data at the subscale level for the YPI, and at the item level for the YPI-S. The internal consistency of the YPI and YPI-S scores ranged from marginal to good. Both t…
Assessment of the reliability, validity, and responsiveness of a Spanish Asthma Quality of Life questionnaire.
1998
A Spanish-language questionnaire designed for measuring the impact of asthma on quality of life in adults was developed. It was derived, by the application of a rigorous translation protocol, from a previously validated, English-language Asthma Quality of Life (AQL) questionnaire which had been developed in Australia. The aim of this study was to evaluate the psychometric properties of the Spanish AQL questionnaire using a cross-sectional and longitudinal design. Two hundred ninety-four clinically stable subjects with asthma (168 women, mean baseline forced expiratory volume in 1 sec [FEV1] = 85% predicted), aged 17-70, attended for the initial baseline assessment. All subjects completed th…
Subjective symptomatology of asthma: validation of the asthma symptom checklist in an outpatient Spanish population.
1997
The objective of this study was to validate the Asthma Symptom Checklist (ASC) so that it could be reliably used to assess the subjective symptomatology of asthma attacks in our context. Subjective symptomatology of asthma was examined in a group of 100 adult Spanish outpatients (57 women, 43 men; 17-69 years of age) with asthma. All of them completed the modified version of the ASC as well as questionnaires of depression, anxiety, and self-management of asthma (self-efficacy expectancies and health care utilization). Data about duration and severity of asthma, as well as dyspnea and %FEV1, were also recorded. The highest reliability Cronbach alpha indexes were for the panic-fear and fatigu…
Randomized Controlled Trials and real life studies. Approaches and methodologies: a clinical point of view.
2014
Randomized Controlled Trials (RCTs) are the "gold standard" for evaluating treatment outcomes providing information on treatments "efficacy". They are designed to test a therapeutic hypothesis under optimal setting in the absence of confounding factors. For this reason they have high internal validity. The strict and controlled conditions in which they are conducted, leads to low generalizability because they are performed in conditions very different from real life usual care. Conversely, real life studies inform on the "effectiveness" of a treatment, that is, the measure of the extent to which an intervention does what is intended to do in routine circumstances. At variance to RCTs, real …
