Reliability and validity of the Newcastle Scales in relation to ICD-9-classification

1987

The assessment of endogenous depression by means of the Newcastle Scales (1965, 1971) has been validated by their correlation with biological findings in many previous studies. However, reliability and cross validation studies are lacking for these scales. We found the reliability of the Newcastle Scales to be sufficient or at least moderate in a sample of 70 inpatients with major depression. In order to cross validate both scales, the clinical classification according to ICD-9 and the assessment of the Newcastle Scales have been performed independently in a sample of 112 inpatients with Major Depressive Disorder (RDC). The rate of agreement between clinical diagnosis and classification acc…

Evaluation of standardized rater training for the Positive and Negative Syndrome Scale (PANSS)

1998

The Positive and Negative Syndrome Scale (PANSS) is employed increasingly for the evaluation of therapeutic outcome in studies on schizophrenia. Rater training is important to improve the concordance and accuracy of ratings; however, there are no established guidelines for carrying out such training. We conducted rater training, under clinical conditions, of psychiatrists and clinical psychologists who were rather unfamiliar with the PANSS. Based on videotapes of PANSS interviews, all participants were trained during five successive standardized weekly sessions. The results were analyzed with respect to conventional criteria of concordance with standard expert ratings and interrater reliabi…

Psychometric properties of the General Self Efficacy-12 Scale in Spanish: general and clinical population samples.

2014

The General Self Efficacy Scale (GSES-12) is a short version of the Sherer’s Self-Efficacy Scale, and evaluates a general dimension and three aspects of self-efficacy: initiative, persistence and effort. The aim of this study is to explore the factorial structure, reliability, and criterion validity of the Spanish adaptation of the GSES-12 in general and clinical populations. The sample was composed of 714 volunteers (332 from the clinical population). Results of the principal components analysis yielded a 3-factor structure that was later confirmed through Confirmatory Factor Analysis. Moreover, this study shows good internal consistency and testretest values, and differences in self-effic…

Development of a new measure for assessing insight: Psychometric properties of the insight orientation scale (IOS)

2015

Abstract Introduction Given the centrality of insight in promoting change, the relevance of measures for assessing this construct has become increasingly clear. This paper describes a new self-report measure for assessing some of the characteristics of insight, the insight orientation scale (IOS). Aims In study 1, we evaluated the factor structure and the reliability of the scale. In study 2, we analyzed the concurrent and discriminant validity of the scale in patients with different clinical diagnoses. Methods In study 1 participants were 600 individuals (41.1% male, 58.9% female) with a mean age of 33.95 years (SD = 13.04). In study 2 participants were 136 individuals divided into the fol…

Empathy in nurses: Spanish adaptation of the Jefferson scale of empathy (JSE) on nurses.

2020

Background: Empathy is a key skill for nurses for providing high-quality care. Aims: To adapt and explore the psychometric properties of the Jefferson Scale of Empathy (JSE) for nursing students in a sample of Spanish nurses, to analyse the empathy levels and to provide some percentiles for interpreting empathy levels. Methods: Factor structure was evaluated with exploratory and confirmatory factor analysis (EFA, CFA), and reliability was evaluated with Cronbach's alpha, composite reliability (CR), and average variance extracted (AVE) in a convenience sample of 500 Spanish nurses. Results: The definitive model composed of 15 items grouped into three factors presented good psychometric prope…

Reliability and Validity of a Further Tested Appreciative Management Scale

2020

Background and PurposeManagers need evidence-based methods to evaluate their management skills. To further test the appreciative management scale (AMS 1.0) to create a practical instrument to be used in evaluating appreciative management.MethodsFor further testing, a new survey was conducted among social and healthcare managers (n = 734) in Finland. Confirmatory factor analysis (CFA) was used to assess the scale validity and Cronbach's alpha coefficients the internal consistency.ResultsThe validated AMS 2.0 scale includes 24 items. The values measuring validity and reliability were good, with an Rool Mean Square Error of Approximation (RMSEA) of 0.072, Average Variance Extracted (AVE) value…

Concurrent Criterion-related Validity, Reliability, and Responsiveness to Treatment of the Figure-of-Four Position for Measurement of Anterior Hip Jo…

2018

Abstract Objective The objective of this study was to examine the intra- and intertester reliability, concurrent criterion-related validity, and responsiveness to treatment of the “figure-of-four” position. Methods A total of 52 asymptomatic male soccer players participated in this study. The intraclass correlation coefficient (2, 1) was used to determine intra- and intertester reliability of the figure-of-four position. Pearson product moment correlation coefficients examining the association between the figure-of-four position and goniometric measurements of hip extension and external rotation were used to establish concurrent validity. To evaluate responsiveness to treatment, the figure-…

Test–Retest Reliability and Temporal Agreement of Direct and Indirect Sexual Interest Measures

2020

The Explicit and Implicit Sexual Interest Profile (EISIP) is a multimethod measure of sexual interest in children and adults. It combines indirect latency-based measures such as the Implicit Association Test (IAT), Viewing Time (VT), and explicit self-report measures. This study examined test–retest reliability and absolute temporal agreement of the EISIP over a 2-week interval in persons who were convicted of sexual offenses against children ( n = 33) and nonoffending controls ( n = 48). Test–retest reliability of the aggregated EISIP measures was high across the whole sample ( rtt = .90, intraclass correlation coefficient [ICC] = .90) with the IAT yielding the lowest retest correlations …
