Two Measures

OBJECTIVE: Evaluate the Glasgow outcome scale (GOS) at discharge (GOS-HD) as a prognostic indicator in patients with traumatic brain injury (TBI). METHOD: Retrospective data were collected of 45 patients, with Glasgow coma scale <8, age 25±10 years, 36 men, from medical records. Later, at home visit, two measures were scored: GOS-HD (according to information from family members) and GOS LATE (12 months after TBI). RESULTS: At discharge, the ERG showed: vegetative state (VS) in 2 (4%), severe disability (SD) in 27 (60%), moderate disability (MD) in 15 (33%) and good recovery (GR) in 1 (2%). After 12 months: death in 5 (11%), VS in 1 (2%), SD in 7 (16%), MD in 9 (20%) and GR in 23 (51%). Variables associated with poor outcome were: worse GOS-HD (p=0.03), neurosurgical procedures (p=0.008) and the kind of brain injury (p=0.009). CONCLUSION: The GOS-HD was indicator of prognosis in patients with severe TBI.

Background and PurposeThe purpose of this study was to assess psychometric properties of the Perceptions of Brain Injury Survey (PBIS), an instrument designed to assess nurses' perceptions and preparation to care for patients with traumatic brain injury (TBI).MethodsWe adapted two instruments to create the PBIS, and 724 nurses completed the PBIS at three hospitals.ResultsFinal instrument has 66 items and is composed of four subscales, which can be used independently. Results showed Cronbach's alpha for the overall scale was excellent (.93) and alphas for each composite subscale were acceptable to excellent (.73–.93). Findings also suggest good discriminant validity and evidence of external validity.ConclusionsThe PBIS is a reliable and valid measure for assessing nurses' perceptions of caring for patients with TBI in practice or research.

Background: The dimensionality of depression and anxiety instruments have recently been a source of controversy. Objectives and Design: In a European-wide sample of patients after Traumatic Brain Injury (TBI), we aim to examine the factorial structure, validity, and association of the Patient Health Questionnaire for depression (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) instruments. This study is based on longitudinal observational data. We conducted analyses of factorial structure and discriminant validity of outcomes six-months after TBI. We also examined the prevalence, co-occurrence, and changes of scores on the PHQ-9 and GAD-7 at 3-, 6-, and 12-month post-TBI assessments. Participants: At six-months post-TBI assessment, 2137 (738 (34.5%) women) participants completed the PHQ-9 and GAD-7 questionnaires. For the longitudinal analysis, we had 1922 participants (672 (35.0%) women). Results: The results of exploratory factor analysis suggested a general latent construct underlying both PHQ-9 and GAD-7 measures. Confirmatory factor analyses showed a slight improvement in the fit indices for the bifactorial model. The Omega hierarchical test clearly differentiated two subfactors of PHQ-9 and GAD-7 items over and above the underlying general factor; however, most of the variance (85.0%) was explained by the general factor and the explained variance of the subfactors was small. The PHQ-9 and GAD-7 performed similarly in detecting post-traumatic stress disorder (PTSD). As defined by conventional cut-offs, depression and anxiety have different prevalence rates in the sample. The scales also differed in their relationships with the short form of health survey (SF-36v2) subscales. The longitudinal analysis showed high stability of depression and anxiety symptoms: 49–67% of the post-TBI patients with comorbid depression and anxiety reported the persistence of the symptoms over time. Discussion: The factorial structure analysis favors a general latent construct underlying both depression and anxiety scales among patients after TBI. We discuss the implications our findings and future research directions.

Two Measures

In this paper two measures of involvement, the Personal Involvement Inventory and the Consumer Involvement Profile, were tested for both convergent and discriminant validity in the context of a high involvement product and a low involvement product. The results show that convergent validity does exist between the two measures. In addition, the research depicted the two measures as exhibiting discriminant validity relative to innovativeness and confidence in information processing but not in terms of attitude toward the object and attitude toward the act. Relatively speaking, the high involvement product showed less convergent validity and more discriminant validity than the low involvement product. The research is based on data collected from 76 undergraduate university students.

Selection Of

This study examined the interrelations of 7 objective product features and 3 subjective product features using two measures for each interrelationship. An adaption of the 1959 Campbell and Fiske multitrait-multimethod analysis indicated significant and acceptable convergent and discriminant validity for the objective product features and the subjective product features, respectively. Undergraduate business school students served as the subjects and the stimulus object was a clock radio.

AbstractUnderstanding happiness and well-being has been one of the central issues for psychologists in recent decades. Happiness orientations have been identified as important pathways toward different types of well-being, and so the development and validation of scales for their measurement is an important step in their study. The present research aims to adapt and validate the Spanish Orientations to Happiness Scale (SOTH), a 6-item scale based on the Orientations to Happiness Questionnaire. This brief scale, which measures hedonic and eudemonic orientations, was administered to 1,647 Spanish workers. Scale structure was subjected to exploratory (EFA) and confirmatory (CFA) factor analysis to obtain evidence of factorial validity. Evidence for convergent validity was assessed by correlating the scale with two measures of hedonic and eudaimonic well-being, and discriminant validity was assessed with the average variance extracted (AVE). Results of EFA showed a two-factor solution, and CFA partially supported this structure, χ2(8,N= 793) = 36.61, p < .001; RMSEA = .06; SRMR = .05; CFI = .97; ACFI = .96. Results also demonstrated appropriate convergent and discriminant validity. The SOTH Scale has been shown to be reliable (CR indices > .72) and valid (AVE = .50), and so it is a valuable tool for assessing orientations to happiness in the Spanish context. Finally, the scientific value and practical utility of the scale are discussed.
