Psychometric evaluation of the Clinical Outcome in Routine Evaluation – General Population: Czech version

Objectives. This study aimed to assess psychometric properties, such as reliability, construct validity, and cut-off scores, for the Czech version of the Clinical Outcome in Routine Evaluation – General Population (GP-CORE) questionnaire, a tool usable for repeated measurement of psychological distress within routine clinical settings. Participants and setting. Two general populations and one clinical sample were used with N values of 420, 394, and 345, respectively. Hypotheses. One of the competing theoretical factor solutions will demonstrate the best fit. Statistical analysis. To examine the factor structure of the GP-CORE, a confirmatory multidimensional item response theory analysis (graded response model) was employed. Results. The best fitting model was a bifactor solution representing one content domain of overall distress and two item wording domains (positively and negatively worded items). Clinical cut-off scores were determined to be 1.85 (men) and 1.90 (women). Study limitations. The GP-CORE can be used as an unidimensional measure of overall distress, but users have to be aware of the influence of positive vs. negative item wording on the responses.

Abstract Objective The Texas Functional Living Scale (TFLS) is a performance-based measure of functional abilities assessing the domains of time, money and calculation, communication, and memory. It is likely that certain items are more sensitive at different levels of functional impairment, with some signaling milder degrees of functional difficulty. This study analyzed psychometric characteristics of individual TFLS items using item response theory (IRT) in an outpatient clinical sample. Method In total, 270 adult outpatients completed the TFLS during clinical neuropsychological evaluation. IRT analysis using 2PL and graded response model was applied to the TFLS. Results Item parameters, item characteristic curves, and information curves were produced. Item difficulty (a) parameters ranged from 1.05 to 2.23, and item discrimination (b) parameters ranged from −4.11 to 0.51. Conclusions TFLS items were differentially sensitive along the continuum of functional impairment. Items that were most sensitive to milder degrees of functional impairment involved clock drawing, microwave programming, financial calculation, and prospective memory. Other items that were optimally precise in more severe degrees of functional impairment involved interacting with a calendar and a relatively simple financial calculation task. These findings suggest that the ability to pass at least some of the items on the TFLS may not necessarily reflect fully intact functional abilities. Certain TFLS items may be able to detect the presence of subtle functional difficulties.

Reliable and valid self-report questionnaires could be useful as initial screening instruments for social phobia in both clinical settings and general populations. The present study investigates the factor structure and psychometric properties of the Social Phobia and Anxiety Inventory for Children (SPAI-C) in a sample of 228 children from the Italian general population aged 8 to 11. The children were asked to complete the Italian version of the SPAI-C and the Screen for Child Anxiety Related Emotional Disorders (SCARED) questionnaire. Confirmatory factor analyses revealed that social phobia can be conceptualized as a unitary construct consisting of five distinct but interrelated symptom clusters named Assertiveness, General Conversation, Physical/Cognitive Symptoms, Avoidance, and Public Performance. Internal consistency of the SPAI-C total scores and two subscales was good; correlations between SPAI-C total scores and SCARED total scores/subscales ranged from moderate to high (Generalized Anxiety Disorder, for social phobia), with the SCARED Social Phobia subscale as the best predictor of SPAI-C total scores. The results indicate that the SPAI-C is a reliable and sensitive instrument suitable for identifying Social Phobia in the young Italian general population.

Abstract. Evidence-based assessment is necessary as a first step for developing psychopathological studies and assessing the effectiveness of empirically validated treatments. There are several measures of obsessive-compulsive disorder (OCD) and/or symptomatology in children and adolescents, but all of them present some limitations. The Obsessive-Compulsive Inventory-Revised (OCI-R) by Foa and her colleagues has showed to be a good self-report measure to capture the dimensionality of OCD in adults and adolescents. The child version of the OCI (OCI-CV) was validated for clinical children and adolescents in 2010, showing excellent psychometric properties. The objective of this study was to examine the factor structure and invariance of the OCI-CV in the general population. Results showed a six-factor structure with one second-order factor, good consistency values, and invariance across region, age, and sex. The OCI-CV is an excellent inventory for assessing the dimensions of OCD symptomatology in general populations of children and adolescents. The invariance across sex and age warrants its utilization for research purposes.

(1) Background: The COVID-19 outbreak has created pressure in people’s daily lives, further threatening public health. Thus, it is important to assess people’s perception of stress during COVID-19 for both research and practical purposes. The Perceived Stress Scale (PSS) is one of the most widely used instruments to measure perceived stress; however, previous validation studies focused on specific populations, possibly limiting the generalization of results. (2) Methods: This study tested the psychometric properties of three versions of the Chinese Perceived Stress Scale (CPSS-14, CPSS-10, and CPSS-4) in the Chinese general population during the COVID-19 pandemic. A commercial online survey was employed to construct a nationally representative sample of 1133 adults in Mainland China (548 males and 585 females) during a one-week period. (3) Results: The two-factor (positivity and negativity) solution for the three versions of the CPSS showed a good fit with the data. The CPSS-14 and CPSS-10 had very good reliability and the CPSS-4 showed acceptable reliability. Scores on all three versions of the CPSS were significantly correlated in the expected direction with health-related variables (e.g., depression, anxiety, and perceived COVID-19 risk), supporting the concurrent validity of the CPSS. (4) Conclusions: All three versions of the CPSS appear to be appropriate for use in research with samples of adults in the Chinese general population under the COVID-19 crisis. The CPSS-10 and CPSS-14 both have strong psychometric properties, but the CPSS-10 would have more utility because it is shorter than the CPSS-14. However, the CPSS-4 is an acceptable alternative when administration time is limited.

Depressive States

The prevalence of depressive symptoms was estimated in a random sample of an Australian general population by administration of the Zung Self-Rating Depression Scale (S.D.S.). Rates, calculated according to criteria derived from a previously studied clinical sample, were somewhat higher in this population than had been reported in similar studies elsewhere. It was reasoned that this finding related to the relative laxity of criteria employed in the present study. Socio-demographic influences on the reporting of depressive symptoms were evident, the most prominent of these being the sex of the subject. It was suggested that these influences may underlie socio-demographic differences in rates of recognized depressive states occurring within clinical samples.

ObjectiveBicuspid aortic valve (BAV) has been associated with less atherosclerosis as compared with tricuspid aortic valve (TAV) patients. It, however, remains unclear whether this reflects the older age of TAV patients and/or accumulation of atherosclerotic risk factors or that the BAV phenotype is atheroprotective. Therefore, we compared the atherosclerotic disease burden of BAV and TAV patients, with that of the general (age-matched) population.MethodsThe prevalence of coronary artery disease (CAD) and CAD risk factors in BAV and TAV patients who underwent aortic valve surgery were compared with the Dutch general practitioners registry data. BAV (n=454) and TAV (n=1101) patients were divided into four groups: BAV with aortic valve stenosis (BAV-AoS), BAV with aortic valve regurgitation (BAV-AR), TAV with AoS (TAV-AoS) and TAV with AR (TAV-AR). The atherosclerotic disease burden of each group was compared with that of the corresponding age cohort for the general population.ResultsCAD risk factors hypertension and hypercholesterolaemia were more prevalent in the surgery groups than the age-matched general population (all p<0.001). All BAVs (BAV-AoS and BAV-AR) and TAV-AR had a similar incidence of CAD history as compared to the age-matched general populations (p=0.689, p=0.325 and p=0.617 respectively), whereas TAV-AoS had a higher incidence (21.6% versus 14.9% in the age-matched general population, p<0.001).ConclusionsStenotic TAV disease is part of the atherosclerotic disease spectrum, while regurgitant TAV and all BAVs are not. Although the prevalence of cardiovascular risk factors is higher in all BAV patients, the prevalence of CAD is similar to the general population.

Item response theory (IRT) was separately applied to parent- and teacher-rated symptoms of attention-deficit/hyperactivity disorder (ADHD) from a pooled sample of 526 six- to twelve-year-old children with and without ADHD. The dimensional structure ADHD was first examined using confirmatory factor analyses, including the bifactor model. A general ADHD factor and two group factors, representing inattentive and hyperactive/impulsive dimensions, optimally fit the data. Using the graded response model, we estimated discrimination and location parameters and information functions for all 18 symptoms of ADHD. Parent- and teacher-rated symptoms demonstrated adequate discrimination and location values, although these estimates varied substantially. For parent ratings, the test information curve peaked between −2 and +2 SD, suggesting that ADHD symptoms exhibited excellent overall reliability at measuring children in the low to moderate range of the general ADHD factor, but not in the extreme ranges. Similar results emerged for teacher ratings, in which the peak range of measurement precision was from −1.40 to 1.90 SD. Several symptoms were comparatively more informative than others; for example, is often easily distracted (“Distracted”) was the most informative parent- and teacher-rated symptom across the latent trait continuum. Clinical implications for the assessment of ADHD as well as relevant considerations for future revisions to diagnostic criteria are discussed.
