Abstract INTRODUCTION Subjective cognitive dysfunction is an important outcome measure in neuro-oncology and may provide additional information beyond performance-based neuropsychological testing. The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is a frequently used quality of life (QoL) measure that includes indices of physical, emotional, social, and neurologic aspects of disease, but does not measure cognitive concerns. This study seeks to develop and validate an index of self-reported cognition derived from existing items on the FACT-Br. METHODS 145 patients (Mage=51.08, Medu=15.63) with heterogeneous brain tumor diagnoses completed neuropsychological evaluation including cognitive testing and self-report measures. Nine FACT-Br items regarding cognition were combined to form the Cognitive Index (CI). Reliability of the CI was measured with Cronbach’s alpha. Concurrent validity was assessed by correlating the CI with the Patient-Reported Outcomes Measurement Information System (PROMIS) Cognitive Abilities-8 or PROMIS Cognitive Concerns-8. Discriminant validity was assessed by correlation of the CI with other FACT-Br indices and the Beck Depression and Anxiety Inventories (BDI, BAI). RESULTS Internal consistency within the CI was high (Cronbach’s a 0.864). The CI correlated strongly with the PROMIS-Abilities (r =.680; p< 0.001) and PROMIS-Concerns (r=.780; p< 0.001) indicating high convergent validity. Moderate correlations were observed between the CI and the physical and functional subscales of the FACT (r=.453 and .555), whereas correlations with the social and emotional functioning subscales were weaker (r=.381 and .325). The FACT-Br-CI correlated strongly with BDI (r=-.622) and more weakly with the BAI (r=-.344). Consistent with prior literature, the CI showed modest correlations with neuropsychological measures, including verbal memory encoding (r=.300), verbal fluency (r=.252) and a composite measure of cognition (r=.249; all p’s< .01). CONCLUSIONS The FACT-Br-CI is a reliable and valid measure of self-reported cognition. Studies that include the FACT-Br could be retrospectively analyzed to assess self-reported cognitive outcomes, enriching the information gained from prior research.

Background: Cognitive impairment is among the most debilitating outcomes of multiple sclerosis (MS). Although several neuropsychological tests and self-report cognitive measures have been used to assess cognitive impairment, they may not be sensitive to change over time, or may not be feasible to administer in a clinical setting. The purpose of this study was to assess the reliability and validity of the 8-item PROMIS Cognitive Abilities and Cognitive Concerns Scales in a large community-based sample of people with MS. The PROMIS Cognitive Abilities and Cognitive Concerns Scales derive from the National Institutes of Health–funded Patient Reported Outcomes Measurement Information System (PROMIS), an item repository that capitalizes on recent psychometric advances to produce short, psychometrically sound health measures. Methods: Mailed survey data were collected from 322 individuals recruited from two National Multiple Sclerosis Society chapters in a southwestern state. Results: Both cognitive scales demonstrated high internal consistency reliability and were moderately correlated with self-reported depressive symptoms, self-efficacy, barriers to health promotion, health, and functional status (all correlation coefficients >0.35). In hierarchical regression analysis, the PROMIS Cognitive Concerns score added significant unique variance to the prediction of MS Incapacity Status after controlling for self-reported depressive symptoms, exercise, spiritual growth, and global health. Those who were unemployed owing to their disabilities had significantly lower PROMIS Cognitive Abilities scores and higher Cognitive Concerns scores than those who were working or those who were retired or not working for other reasons. Conclusions: The PROMIS Cognitive Abilities and Cognitive Concerns Scales are short, psychometrically sound measures that assess an important dimension of functioning and health for people with MS.

Trust Scale

Across the social sciences, generalized trust has been one of the most frequently examined constructs since researchers first introduced measures of it in the 1950s. Despite its significance, there is growing consensus that conventional measures of generalized trust are prone to measurement invalidity and non-equivalence, which places sociological knowledge about generalized trust in serious doubt. In this article, I advance trust research in sociology by (1) refining two new self-report measures of generalized trust—the Stranger Face Trust scale (SFT) and the Imaginary Stranger Trust scale (IST)—and (2) assessing their empirical performance on a nationally representative probability sample (N = 1,264). I compare the reliability and validity of SFT, IST, and traditional measures of generalized trust across a number of measurement validation tests (convergent validity, discriminant validity, known-groups validity, and predictive validity). Results suggest that SFT provides the most accurate and consistent measure of generalized trust. I conclude by discussing the implications of my findings for sociological knowledge.

Validity Measures

The reliability and validity of the Psychopathy Checklist–Revised (PCL–R) was examined in a sample of 528 nonpsychotic female offenders participating in a study assessing the generalizability of the instrument to females using personality, attitudinal, and laboratory behavioral measures. Results showed good interrater reliability and adequate internal consistency. Correlations with a number of self-report validity measures and previous criminal behavior provide support for the convergent validity of the instrument. A lack of association with general psychopathology provides support for the discriminant validity of the instrument. However, significant correlations with anxiety, negative affectivity, and intelligence run counter to expectations and to findings with male offenders. Furthermore, the low base rate of psychopathy in this sample, relative to base rates among male prisoners, raises the concern that either psychopathy is less prevalent in females than in males or the PCL–R is not adequately assessing the construct in female offenders.

Purpose Depression assessment is challenging in persons with aphasia given their language impairment. Studies have used both self-report scales and by-proxy measures of depression in persons with aphasia. However, the validity of these measures has been called into question. The aim of this study was to conduct a preliminary investigation into aspects of validity of the community version of the Stroke Aphasia Depression Questionnaire (SADQ-10) and the Center for Epidemiological Studies Depression Scale–Revised (CESD-R). Method Twenty-four participants with chronic aphasia completed the CESD-R, the Patient-Reported Outcomes Measurement Information System Global Mental Health scale (PROMIS GMH), and the Dynamic Visual Assessment of Mood Scales (D-VAMS) while their caregivers completed the SADQ-10. Internal consistency of the CESD-R and the SADQ-10 and the convergent validity of the CESD-R, SADQ-10, PROMIS GMH, and D-VAMS were examined. Results The SADQ-10 and the CESD-R were internally consistent. The CESD-R was moderately correlated with the SADQ-10, PROMIS GMH, and D-VAMS. However, the SADQ-10 was not correlated with the PROMIS GMH and D-VAMS. Conclusions We suggest both the CESD-R and the SADQ-10 be used together to screen for depression in persons with aphasia. Further studies with larger sample sizes need to be conducted to establish validity of other depression screening instruments in person with aphasia.

This study examined the reliability and validity of scores from questionnaires assessing compensatory cognitive strategy use by young adults. Participants ( N = 783; 79.6% women; 77.4% White; Age: M = 18.7 ± 0.9 years) completed the Compensatory Cognitive Strategies Scale (CCSS), Metamemory Questionnaire–Strategies (MMQ-S), Neuro-Quality of Life (Neuro-QoL) v2.0 Short Form–Cognitive Function, and Difficulties in Emotion Regulation Scale (DERS). Reliability estimates were acceptable for the CCSS (α = .85) and MMQ-S (α = .86) in the full sample and comparable in subsamples stratified by gender and self-reported mental health conditions. The CCSS and MMQ-S scores showed evidence for convergent validity ( r range: .60 to .70) and discriminant validity in the full sample and subsamples ( r with DERS range: .13 to .33). Greater compensatory strategy use had small-to-medium associations with greater subjective cognitive concerns on the Neuro-QOL for the full sample and subsamples ( r range: −.19 to −.49). The CCSS and MMQ-S scores showed acceptable properties for use with young adults.

Abstract Objectives Existing measures of inflammatory bowel disease (IBD) symptoms are not well suited to self-report, inadequate in measurement properties, insufficiently specific, or burdensome for brief or repeated administration. We aimed to develop a patient-reported outcome measure to assess a broader range of IBD symptoms. Methods The IBD Symptoms Inventory (IBDSI) was developed by adapting symptom items from existing clinician-rated or diary-format inventories; after factor analysis, 38 items were retained on 5 subscales: bowel symptoms, abdominal discomfort, fatigue, bowel complications, and systemic complications. Participants completed the IBDSI and other self-report measures during a clinic visit. A nurse administered the Harvey Bradshaw Index (HBI) for Crohn’s disease (CD) or the Powell-Tuck Index (PTI) for ulcerative colitis (UC), and a gastroenterologist completed a global assessment of disease severity (PGA). Results The 267 participants with CD (n = 142) or UC (n = 125), ages 18 to 81 (M = 43.4, SD = 14.6) were 58.1% female, with a mean disease duration of 13.9 (SD = 10.5) years. Confirmatory factor analysis supported the 5 subscales. The total scale and subscales showed good reliability and significant correlations with self-report symptom and IBD quality of life measures, the HBI, PTI, and PGA. Conclusions The IBDSI showed strong measurement properties: a supported factor structure, very good internal consistency, convergent validity, and excellent sensitivity and specificity to clinician-rated active disease. Self-report HBI and PTI items, when extracted from this measure, produced scores comparable to clinician-administered versions. The 38-item IBDSI, or 26-item short form, can be used as a brief survey of common IBD symptoms in clinic or research settings.

Character strengths are an important foundation for positive development and thriving in adolescence. Most research on character strengths has been conducted with youths in Western cultures. We examined character strengths in relation to positive and negative well-being indicators in a sample of Iranian youths. We investigated the reliability and validity of the Farsi version of the Values in Action Inventory of Strengths for Youth (VIA Y-96)—a self-report survey commonly used in Western contexts. Participants were adolescents in Iran ( N = 1,359; 48.5% female; M age = 13.54, SD = 1.00) who completed the VIA Y-96 and questionnaires assessing life satisfaction, positive/negative experiences, depression, anxiety, and stress. We found that reliability coefficients were acceptable for most of the VIA subscales. A confirmatory factor analysis (CFA), as well as a second-order CFA, supported the construct validity of the Farsi VIA Y-96. Correlations between the character strengths and positive and negative well-being indicators supported convergent validity. Measurement invariance for the VIA Y-96 was established in this study comparing boys’ and girls’ response patterns. Sex and grade level differences were found for some of the subscales. Overall, the Farsi VIA Y-96 had acceptable psychometric properties, suggesting that it can be used in research on character strengths with Iranian youths.

Abstract Objective Insomnia is a highly prevalent sleep disorder that is particularly common among adolescents with health conditions. We aimed to develop and validate a brief screening measure of insomnia in adolescents that can be used across clinical and community samples. We hypothesized that we would identify evidence supporting reliability, convergent/discriminant validity, and that we would determine preliminary clinical cutoff scores. Methods A team of experts in behavioral sleep medicine developed a 13-item brief screening measure of insomnia in adolescents (Adolescent Insomnia Questionnaire [AIQ]). We evaluated the psychometric properties of the AIQ in a sample of 315 youth (11–18 years old, Mean = 14.90, SD = 2.02; 64% female) who had chronic pain (n = 37), headache (n = 170), insomnia diagnosed by a sleep specialist (n = 22), or were otherwise healthy (n = 86). Results Using Exploratory and Confirmatory Factor Analysis, we identified three subscales consistent with major diagnostic criteria of insomnia. As expected, the measure showed strong reliability through high internal consistency (α =.91). We also found strong convergent validity through expected positive relationships between the AIQ and self-report measures of sleep disturbance, and divergent validity via weak relationships with parent-report of snoring. Results of receiver operating characteristic (ROC) identified a clinical cutoff score that may assist in clinical decision making. Conclusions We found that the AIQ has sound psychometric properties in a large heterogeneous sample of treatment-seeking youth and youth from the community. The AIQ can quickly screen adolescent insomnia and could address an important clinical need in identifying youth in need of insomnia treatment in pediatric practice settings.

Metodas parengtas dviem etapais, naudojant empirinę skalių konstravimo strategiją. Pirmajame etape, taikant grupinio interviu ir ekspertinio vertinimo metodus, parengti psichologinio įgalinimo vertinimo teiginiai. Antrajame etape atliktas empirinis tyrimas (dalyvavo 189 tiriamieji, reprezentuojantys 8 Lietuvos organizacijas). Remiantis jo rezultatais parengtas lietuviškas psichologinio įgalinimo vertinimo klausimynas. Tiriamosios faktorių analizės metodu išskirti penki faktoriai: prasmė, entuziazmas, sprendimų priėmimas, autonomija ir pasitikėjimas kompetencija. Klausimynas pasižymi dideliu vidiniu patikimumu (bendras Cronbacho α = 0,909, atskirų subskalių nuo 0,755 iki 0,880), dideliu konvergentiniu ir diskriminantiniu konstrukto validumu tiek viso klausimyno, tiek atskirų penkių skalių lygmeniu.Pagrindiniai žodžiai: psichologinis įgalinimas, psichologinio įgalinimo klausimynas, patikimumas, validumas.EMPLOYEE PSYCHOLOGICAL EMPOWERMENT: PSYCHOMETRIC PROPERTIES OF THE LITHUANIAN QUESTIONNAIREMantas Tvarijonavičius, Dalia Bagdžiūnienė SummaryEmployee psychological empowerment is treated as a multidimensional construct manifesting in several dimensions. It has been researched for several decades using various scales depending on the definition of psychological empowerment chosen by a reasercher. However, there is a lack of widely applicable, compact instruments for a reliable and valid assessment of psychological empowerment. Furthermore, there has been a lack of empowerment research in Lithuania. Therefore, the purpose of this study is to construct a Lithuanian psychological empowerment questionnaire and to evaluate its psychometric properties (reliability and validity).The strategy of the empirical construction of a questionnaire was used. At first, statements to describe the concept of psychological empowerment were generated, using group interviews and expert evaluation. Fifteen final items were included into the Lithuanian Psychological Empowerment Questionnaire (LPEQ). Then, an empirical research was performed: 189 respondents from 8 organizations filled up the LPEQ, G.M. Spreizer (1995) Psychological Empowerment Questionnaire (PEQ), B. E. Ashforth (1990) Helplessness Scale, Intrinsic Motivation Scale (Warr et al., 1979), and socio-demografic questions.The results of the study have revealed that the LPEQ has a high internal reliability (Cronbach α = 0.909). Five factors were extracted using the exploratoryfactor analysis, three items each. Psychological empowerment was defined based on five dimensions: meaning, enthusiasm, decision making, authonomy, and trust in competence. The Cronbach α was between 0.755 and 0.880 for the dimension level. These five dimensions show support for the existing models of psychological empowerment (Spreitzer, 1995; Menon, 2001), but also they supplement these models with for instance, the dimension of enthusiasm.The convergent validity of the LPEQ was confirmed by strong correlations (p < 0.01) between the LPEQ and the PEQ subscales, and the Intrinsic Motivation Scale. It was supported by a negative correlation between the LPEQ subscales and the Helplessness Scale. Based on the analysis of correlations, the discriminant validity of the LPEQ dimensions’ levels was confirmed.In conclusion, the Lithuanian Psychological Empowerment Questionnaire (LPEQ) can be characterized as an instrument with appropriate psychometricproperties for the use in research and practice. Directions for the future research in the field have been offered.Key words: psychological empowerment, psychological empowerment questionnaire, reliability, validity.
