Development and Psychometric Evaluation of an Item Bank for Computerized Adaptive Testing of the EORTC Insomnia Dimension in Cancer Patients (EORTC CAT-SL)

To further advance assessment of patient-reported outcomes, the European Organisation of Research and Treatment of Cancer (EORTC) Quality of Life Group has developed computerized adaptive test (CAT) versions of all EORTC Quality of Life Core Questionnaire (QLQ-C30) scales/items. The aim of this study was to develop and evaluate an item bank for CAT measurement of insomnia (CAT-SL). In line with the EORTC guidelines, the developmental process comprised four phases: (I) defining the concept insomnia and literature search, (II) selection and formulation of new items, (III) pre-testing and (IV) field-testing, including psychometric analyses of the final item bank. In phase I, the literature search identified 155 items that were compatible with our conceptualisation of insomnia, including both quantity and quality of sleep. In phase II, following a multistep-approach, this number was reduced to 15 candidate items. Pre-testing of these items in cancer patients (phase III) resulted in an item list of 14 items, which were field-tested among 1094 patients in phase IV. Psychometric evaluations showed that eight items could be retained in a unidimensional model. The final item bank yielded greater measurement precision than the original QLQ-C30 insomnia item. It was estimated that administering two or more items from the insomnia item bank with CAT results in a saving in sample size between approximately 15–25%. The 8-item EORTC CAT-SL item bank facilitates precise and efficient measurement of insomnia as part of the EORTC CAT system of health-related quality life assessment in both clinical research and practice.

     

Conceptions of Research Methods Learning Among Psychology Undergraduates: A Q Methodology Study*

Abstract

A range of conceptions held about research methods learning have previously been identified. This study aimed to examine in-depth shared conceptions among undergraduate psychology students. Utilizing Q methodology, which links both quantitative and qualitative methodologies to uncover the subjective viewpoints that a group of individuals hold toward a particular domain, participants ranked statements reflecting different conceptions of research methods learning. Ranks were then factor analyzed and four distinct profiles of student conceptions were identified, labelled, and described in qualitative detail: research methods as integral to psychology, research methods as a digression from psychology, research methods as disconnected from psychology, and research methods as beneficial to psychology. Some of the perspectives displayed a clear understanding about the reasons for undertaking research and learning about research methods in psychology, whereas other standpoints saw research as being something that was difficult to relate to the practice of psychology. Findings are considered in terms of how some conceptions appear to be more beneficial or problematic to hold than others and recommendations are made to educators about how they could support students to change their views.     

Affective valence and P300 when stimulus arousal level is controlled

Visual stimuli from the International Affective Picture System (IAPS) were employed in a modified oddball paradigm to elicit the P300 event-related brain potential (ERP) in young adult females (N=12). The pictures varied on valence (negative, neutral, positive) ratings but had the same medium arousal level ratings. The images were presented as targets with a standard stimulus composed of red/white triangles designed to mimic the spatial frequency of the pictures. P300 amplitude from negative relative to neutral stimuli was smaller over frontal areas, whereas amplitude from positive relative to neutral stimuli did not differ. P300 amplitude differences among valence categories were consistent across the midline electrodes, and did not change over the parietal area where arousal effects are typically observed. The findings suggest that valence affects P300 frontal amplitude, and arousal level should be controlled when using emotional stimuli to elicit ERPs. Theoretical implications are discussed.     

Cognitive-behavioral therapy for insomnia in alcohol dependent patients: a randomized controlled pilot trial

In a randomized controlled trial, we evaluated the efficacy of cognitive-behavioral treatment for insomnia to improve sleep and daytime symptoms, and to reduce relapse in recovering alcohol dependent (AD) participants. Seventeen abstinent AD patients with insomnia (6 women, mean age 46.2 ± 10.1 years) were randomized to 8 sessions of cognitive-behavioral treatment for insomnia for AD (CBTI-AD, n = 9) or to a behavioral placebo treatment (BPT, n = 8). Subjective measures of sleep, daytime consequences of insomnia and AD, alcohol use, and treatment fidelity were collected at baseline and post-treatment. Diary-rated sleep efficiency and wake after sleep onset, and daytime ratings of General Fatigue on the Multidimensional Fatigue Inventory improved more in the CBTI-AD compared to the BPT group. In addition, more subjects were classified as treatment responders following CBTI-AD. No group differences were found in the number of participants who relapsed to any drinking or who relapsed to heavy drinking. The findings suggest that cognitive-behavioral insomnia therapy benefits subjective sleep and daytime symptoms in recovering AD participants with insomnia more than placebo. The benefits of treating insomnia on drinking outcomes are less apparent.     

The influence of political climate on job pursuit intentions and the moderating effect of Machiavellianism

Job seekers now have access to a number of internet resources (e.g., social media, chat rooms, and message boards) that provide information about potential employers. These resources provide potential job applicants with extensive amounts of third‐party information about organizations, including information about the extent to which a particular organization's climate can be characterized as being political. Unfortunately, owing to a dearth of research on this topic, it is unclear to what extent such information about an organization's political climate might affect the recruiting process. Therefore, drawing from the Attraction‐Selection‐Attrition model, we considered the extent to which potential job applicants are less (more) likely to pursue jobs in organizations that are perceived as more (less) political. We further identified Machiavellianism as a potential moderator of this relationship, given that this trait reflects the extent to which an individual would “fit” into a highly political work environment. Across three studies, our findings provide evidence that job applicants report being less likely to pursue jobs in organizations characterized by high levels of workplace politics. The results further indicated that Machiavellianism attenuates this negative effect. In light of our findings, we discuss implications for how information that is not controlled by the organization (e.g., information provided by social media or other internet‐based sources) affects job pursuit intentions and the organization's applicant pool.

The Expression of Achievement Motives in Interpersonal Problems

ABSTRACT Achievement motivation influences self-regulatory strategies, affective processes, and achievement outcomes, but little is known about how individual differences in achievement motivation influence interpersonal behavior. Different forms of achievement motivation are likely to influence interpersonal behavior because achievement motives are grounded in social emotions. Two studies were conducted to examine relations between achievement motives and dispositional interpersonal problems. These studies linked deficits in pride-based need for achievement with self-reported submission-related interpersonal problems, and shame-based fear of failure (FF) with both self- and peer-reported interpersonal distress. The achievement motives were largely not associated with individuals' perceptions of their peers' interpersonal problems. These findings reinforce propositions that FF represents the commingling of achievement and relational concerns and suggest new mechanisms by which achievement motives may influence productivity, social success, and well-being.     

Lethality of suicide attempt rating scale

An 11-point (0-10) scale for measuring the degree of lethality of suicide attempts is presented. The scale has nine example "anchors" and uses the relative lethality of an extensive table of drugs. The psychometric studies show the scale to be of at least equal-interval, possibly even ratio measurement level. The equal-interval quality allows suicidal behaviors to be specified in numeric relationship to each other relieving us of the burden of using unquantified labels such as "mild," "moderate," and "serious." Having a standardized, commonly used reference scale should greatly facilitate our research and clinical efforts to communicate our findings. The scale can be used reliably by nonmedical personnel with no prior training.
