Steps toward preregistration of research on research integrity.

Background: A proposal to encourage the preregistration of research on research integrity was developed and adopted as the Amsterdam Agenda at the 5th World Conference on Research Integrity (Amsterdam, 2017). This paper reports on the degree to which abstracts of the 6th World Conference in Research Integrity (Hong Kong, 2019) reported on preregistered research.

Methods: Conference registration data on participants presenting a paper or a poster at 6th WCRI were made available to the research team.

Self-esteem and satisfaction with social relationships across time.

Research on the longitudinal association between self-esteem and satisfaction with social relationships has led to ambiguous conclusions regarding the temporal order and strength of this relation. Existing studies have examined this association across intervals ranging from days to years, leaving it unclear as to what extent differences in timing may explain differences across studies. In the present study, we used continuous time structural equation models (i.

Health-related quality of life after Gamma Knife radiosurgery in patients with 1-10 brain metastases.

Purpose: Increasingly more patients with multiple (> 4) brain metastases (BM) are being treated with stereotactic radiosurgery (SRS). Preserving patients' health-related quality of life (HRQoL) is an important treatment goal. The aim of this study was to assess (individual) changes in HRQoL in patients with 1-10 BM over time.

Bias and Precision of Continuous Norms Obtained Using Quantile Regression.

Continuous norming is an increasingly popular approach to establish norms when the performance on a test is dependent on age. However, current continuous norming methods rely on a number of assumptions that are quite restrictive and may introduce bias. In this study, quantile regression was introduced as more flexible alternative.

Precision and Sample Size Requirements for Regression-Based Norming Methods for Change Scores.

To interpret a person's change score, one typically transforms the change score into, for example, a percentile, so that one knows a person's location in a distribution of change scores. Transformed scores are referred to as norms and the construction of norms is referred to as norming. Two often-used norming methods for change scores are the regression-based change approach and the Scores for Change method.

Assessment of Executive Functioning in Patients with Meningioma and Low-Grade Glioma: A Comparison of Self-Report, Proxy-Report, and Test Performance.

Objective: This study aimed to examine: (1) patient-proxy agreement on executive functioning (EF) of patients with primary brain tumors, (2) the relationships between patient- and proxy-report with performance-based measures of EF, and (3) the potential influence of performance-based measures on the level of agreement.

Methods: Meningioma and low-grade glioma patients and their informal caregivers completed the Behavior Rating Inventory of Executive Function (BRIEF-A) 3 months after surgery. The two index scores of the BRIEF-A, Behavioral Regulation and Metacognition, were evaluated.

The Assessment and Impact of Careless Responding in Routine Outcome Monitoring within Mental Health Care.

Careless responding by mental health patients on self-report assessments is rarely investigated in routine care despite the potential for serious consequences such as faulty clinical decisions. We investigated validity indices most appropriate for detecting careless responding in routine outcome monitoring (ROM) in mental health-care. First, we reviewed indices proposed in previous research for their suitability in ROM.

Modeling Interactions Between Latent Variables in Research on Type D Personality: A Monte Carlo Simulation and Clinical Study of Depression and Anxiety.

Several approaches exist to model interactions between latent variables. However, it is unclear how these perform when item scores are skewed and ordinal. Research on Type D personality serves as a good case study for that matter.

Alexithymia Has No Clinically Relevant Association With Outcome of Multimodal Treatment Tailored to Needs of Patients Suffering From Somatic Symptom and Related Disorders. A Clinical Prospective Study.

Alexithymia may moderate the effectiveness of treatment and may predict impaired general functioning of patients suffering from somatic symptom and related disorders (SSRD). We compared alexithymia levels in a clinical prospective study with 234 consecutive patients suffering from SSRD from the Centre of Excellence for Body, Mind, and Health, Tilburg using the Bermond-Vorst Alexithymia Questionnaire, with general population norm scores. Second, we explored treatment outcomes of a multimodal treatment tailored to patient needs by Shared Decision Making (SDM) and Patient Related Outcome Monitoring (PROM) in patients with SSRD.

Test-retest reliability and practice effects of a computerized neuropsychological battery: A solution-oriented approach.

This study examined test-retest reliabilities and (predictors of) practice effects of the widely used computerized neuropsychological battery CNS Vital Signs. The sample consisted of 158 Dutch healthy adults. At 3 and 12 months follow-up, 131 and 77 participants were retested.

Psychometric Properties of the Bermond-Vorst Alexithymia Questionnaire (BVAQ) in the General Population and a Clinical Population.

Introduction: The Bermond-Vorst Alexithymia Questionnaire (BVAQ) has been validated in student samples and small clinical samples, but not in the general population; thus, representative general-population norms are lacking.

Aim: We examined the factor structure of the BVAQ in Longitudinal Internet Studies for the Social Sciences panel data from the Dutch general population ( = 974).

Results: Factor analyses revealed a first-order five-factor model and a second-order two-factor model.

Review of Issues About Classical Change Scores: A Multilevel Modeling Perspective on Some Enduring Beliefs.

Change scores obtained in pretest-posttest designs are important for evaluating treatment effectiveness and for assessing change of individual test scores in psychological research. However, over the years the use of change scores has raised much controversy. In this article, from a multilevel perspective, we provide a structured treatise on several persistent negative beliefs about change scores and show that these beliefs originated from the confounding of the effects of within-person change on change-score reliability and between-person change differences.

A Comparison of Unidimensionality and Measurement Precision of the Narcissistic Personality Inventory and the Narcissistic Admiration and Rivalry Questionnaire.

The current study compares the closeness to unidimensionality (CU) and measurement precision (MP) of the Narcissistic Personality Inventory (NPI)-with either a pairwise forced-choice or 5-point Likert-type scale response format-to the Narcissistic Admiration and Rivalry Questionnaire (NARQ). Minimum rank factor analysis and item information curves from item response models were utilized. The results mainly confirmed our expectations that NPI subscales are lower in CU and MP compared with NARQ subscales when the NPI was administered with its traditional forced-choice response format.

Haptotherapy as a new intervention for treating fear of childbirth: a randomized controlled trial.

Objective: To evaluate the effect of haptotherapy on severe fear of childbirth in pregnant women.

Design: Randomized controlled trial.

Setting: Community midwifery practices and a teaching hospital in the Netherlands.

Evaluation of Normative Data of a Widely Used Computerized Neuropsychological Battery: Applicability and Effects of Sociodemographic Variables in a Dutch Sample.

Central Nervous System Vital Signs (CNS VS) is a computerized neuropsychological battery that is translated into many languages. However, published CNS VS' normative data were established over a decade ago, are solely age-corrected, and collected in an American population only. Mean performance of healthy Dutch participants on CNS VS was compared with the original CNS VS norms ( = 1,069), and effects of sociodemographic variables were examined.

Longitudinal measurement invariance of the Dutch Outcome Questionnaire-45 in a clinical sample.

Purpose: In the absence of measurement invariance across measurement occasions, change scores based on pretest-posttest measurements may be inaccurate representations of real change on the latent variable. In this study, we examined whether measurement invariance held in the Dutch version of Outcome Questionnaire-45 (OQ-45).

Method: Using secondary data analysis of a sample of N = 540 Dutch outpatients, we tested the stability of the factorial structure (gamma change) and the metric and scalar invariance (beta change) across pretest and posttest measurements using a combination of factor analysis and item response theory methodology.

Comparison of Classical Test Theory and Item Response Theory in Individual Change Assessment.

Clinical psychologists are advised to assess clinical and statistical significance when assessing change in individual patients. Individual change assessment can be conducted using either the methodologies of classical test theory (CTT) or item response theory (IRT). Researchers have been optimistic about the possible advantages of using IRT rather than CTT in change assessment.

Response Inconsistency of Patient-Reported Symptoms as a Predictor of Discrepancy Between Patient and Clinician-Reported Depression Severity.

The aim of this study was to assess the extent to which discrepancy between self-reported and clinician-rated severity of depression are due to inconsistent self-reports. Response inconsistency threatens the validity of the test score. We used data from a large sample of outpatients ( N = 5,959) who completed the self-report Beck Depression Inventory-II (BDI-II) and the clinician-rated Montgomery-Åsberg Depression Rating Scale (MADRS).

Comprehensively Measuring Health-Related Subjective Well-Being: Dimensionality Analysis for Improved Outcome Assessment in Health Economics.

Background: Allocation of inevitably limited financial resources for health care requires assessment of an intervention's effectiveness. Interventions likely affect quality of life (QOL) more broadly than is measurable with commonly used health-related QOL utility scales. In line with the World Health Organization's definition of health, a recent Delphi procedure showed that assessment needs to put more emphasis on mental and social dimensions.

Identifying Person-Fit Latent Classes, and Explanation of Categorical and Continuous Person Misfit.

Latent class (LC) cluster analysis of a set of subscale person-fit statistics was proposed to explain person misfit on multiscale measures. The proposed explanatory LC person-fit analysis was used to analyze data of students ( = 91,648) on the nine-subscale School Attitude Questionnaire Internet (SAQI). Inspection of the class-specific mean and variance structure combined with explanatory analysis of class membership showed that the data included a poor-fit class, a class showing good fit combined with social desirability bias, a good-fit class, and two classes that were more difficult to interpret.

The relationship between parenting stress and parent-child interaction with health outcomes in the youngest patients with type 1 diabetes (0-7 years).

Unlabelled: To test whether parenting stress and the quality of parent-child interaction were associated with glycemic control and quality of life (QoL) in young children (0-7 years) with type 1 diabetes (T1DM), we videotaped 77 families with a young child with T1DM during mealtime (including glucose monitoring and insulin administration). Parent-child interactions were scored with a specifically designed instrument. Questionnaires assessed general and disease-related parenting stress and (diabetes-specific (DS)) QoL.

Sex Bias in Classifying Borderline and Narcissistic Personality Disorder.

This study investigated sex bias in the classification of borderline and narcissistic personality disorders. A sample of psychologists in training for a post-master degree (N = 180) read brief case histories (male or female version) and made DSM classification. To differentiate sex bias due to sex stereotyping or to base rate variation, we used different case histories, respectively: (1) non-ambiguous case histories with enough criteria of either borderline or narcissistic personality disorder to meet the threshold for classification, and (2) an ambiguous case with subthreshold features of both borderline and narcissistic personality disorder.

Detecting and Explaining Aberrant Responding to the Outcome Questionnaire-45.

We applied item response theory based person-fit analysis (PFA) to data of the Outcome Questionnaire-45 (OQ-45) to investigate the prevalence and causes of aberrant responding in a sample of Dutch clinical outpatients. The [Formula: see text] person-fit statistic was used to detect misfitting item-score patterns and the standardized residual statistic for identifying the source of the misfit in the item-score patterns identified as misfitting. Logistic regression analysis was used to predict person misfit from clinical diagnosis, OQ-45 total score, and Global Assessment of Functioning code.

Validation of the 4DSQ somatization subscale in the occupational health care setting as a screener.

Purpose: Somatoform disorders (physical symptoms without medical explanation that cause dysfunction) are prevalent in the occupational health (OH) care setting and are associated with functional impairment and absenteeism. Availability of psychometric instruments aimed at assessing somatoform disorders is limited. In the OH setting, so far only the Patient-Health-Questionnaire 15 has been validated as screener for somatoform disorder, and has been shown to have moderate validity.

Explanatory, Multilevel Person-Fit Analysis of Response Consistency on the Spielberger State-Trait Anxiety Inventory.

Self-report measures are vulnerable to concentration and motivation problems, leading to responses that may be inconsistent with the respondent's latent trait value. We investigated response consistency in a sample (N = 860) of cardiac patients with an implantable cardioverter defibrillator and their partners who completed the Spielberger State-Trait Anxiety Inventory on five measurement occasions. For each occasion and for both the state and trait subscales, we used the l (p) z person-fit statistic to assess response consistency.
