Test Retest Reliability

The EEG reflects mental processes, especially modulations in the alpha and theta frequency bands are associated with attention and the allocation of mental resources. EEG has also been used to study mental processes while driving, both in real environments and in virtual reality. However, conventional EEG methods are of limited use outside of controlled laboratory settings. While modern EEG technologies offer hardly any restrictions for the user, they often still have limitations in measurement reliability. We recently showed that low-density EEG methods using film-based round the ear electrodes (cEEGrids) are well-suited to map mental processes while driving a car in a driving simulator. In the present follow-up study, we explored aspects of ecological and internal validity of the cEEGrid measurements. We analyzed longitudinal data of 127 adults, who drove the same driving course in a virtual environment twice at intervals of 12–15 months while the EEG was recorded. Modulations in the alpha and theta frequency bands as well as within behavioral parameters (driving speed and steering wheel angular velocity) which were highly consistent over the two measurement time points were found to reflect the complexity of the driving task. At the intraindividual level, small to moderate (albeit significant) correlations were observed in about 2/3 of the participants, while other participants showed significant deviations between the two measurements. Thus, the test-retest reliability at the intra-individual level was rather low and challenges the value of the application for diagnostic purposes. However, across all participants the reliability and ecological validity of cEEGrid electrodes were satisfactory in the context of driving-related parameters.

The Holyoake Codependency Index is a 13-item self-report measure of three aspects of codependency: External Focus, Self-sacrifice, and a sense of being overwhelmed by another person's problematic behavior (termed Reactivity). Previous studies have supported internal validity and the internal consistency and construct validity of the subscales. The present scores for 59 students indicate full scale test-retest reliability of .88 and for subscales (.76 to .82) over a 3-wk. interval.

Children were observed twice in Ainsworth's Strange Situation to measure the stability of their attachment relationship with the caregiver across 1 mo. To get some insight into the ecological validity of the procedure, the children were randomly divided over four sets of conditions: the home-home, home-lab, lab-home, and lab-lab conditions. The test-retest reliability of the interactive scores was high as was the stability of the classifications. The results of the Strange Situation at home and in the laboratory remain non-comparable.

Resting State Connectivity

AbstractFunctional connectivity analysis has become a powerful tool for probing the human brain function and its breakdown in neuropsychiatry disorders. So far, most studies adopted resting state paradigm to examine functional connectivity networks in the brain, thanks to its low demand and high tolerance that are essential for clinical studies. However, the test-retest reliability of resting state connectivity measures is moderate, potentially due to its low behavioral constraint. On the other hand, naturalistic neuroimaging paradigms, an emerging approach for cognitive neuroscience with high ecological validity, could potentially improve the reliability of functional connectivity measures. To test this hypothesis, we characterized the test-retest reliability of functional connectivity measures during a natural viewing condition, and benchmarked it against resting state connectivity measures acquired within the same functional magnetic resonance imaging (fMRI) session. We found that the reliability of connectivity and graph theoretical measures of brain networks is significantly improved during natural viewing conditions over resting state conditions, with an average increase of almost 50% across various connectivity measures. Not only sensory networks for audio-visual processing become more reliable, higher order brain networks, such as default mode and attention networks, also appear to show higher reliability during natural viewing. Our results support the use of natural viewing paradigms in estimating functional connectivity of brain networks, and have important implications for clinical application of fMRI.

The Impact

Objective: This report presents a French translation and validation of the Impact of Event Scale-Revised (IES-R) in a population of women exposed to a natural disaster during or preceding pregnancy. Method: A total of 223 francophone women who were either pregnant at the time of the 1998 ice storm or who became pregnant shortly thereafter completed the IES-R and other questionnaires 6 months after the disaster. Results: The French IES-R has good internal consistency, with alpha coefficients ranging from 0.81 to 0.93 for its 3 subscales and total score. The test–retest reliability of the scale, although examined with another sample, proved to be satisfactory, with correlation coefficients ranging from 0.71 to 0.76 for its 3 subscales and total score. Its convergent validity with perceived life threat and general psychiatric symptoms was judged to be marginally acceptable. Finally, a principal components analysis was conducted and a 3-factor solution, which explained 56% of the variance, was retained: a hyperarousal factor (7 items), an avoidance factor (6 items), and an intrusion factor (6 items). Conclusions: The French version of the IES-R has satisfactory internal validity and test–retest reliability. Further, the factor structure of the translation was similar to the proposed theoretical structure of the IES-R.

AbstractPurpose:Traumatic brain injury (TBI) often leads to executive functions deficits, which may be responsible for severe and longstanding disabilities in everyday activities. Sensitivity and ecological validity of neuropsychological tests of executive functions have been questioned. The aims of this study were to pilot an ecological open-ended assessment of executive functions in children, the ‘Children's Cooking Task’ (CCT), specifically to report its reliability, discriminant validity and concurrent validity.Methods:Twenty-five children with mild (n= 10) or moderate-to-severe TBI (n= 15), and 21 matched controls (aged 8 to 20 years) participated in the study. An open-ended cooking task was designed to test multi-tasking abilities. It required the preparation of two simple recipes using specific instructions. Outcome measures included the number of errors and an overall qualitative analysis of the task. Validating measures of executive functions included the Delis Kaplan Executive Function System, the Six-Part Test and two questionnaires completed by the child's primary care-giver: the Behavior Rating Inventory of Executive Function and the Dysexecutive Questionnaire for Children.Results:Internal consistency of the Children's Cooking Task was high (Cronbach's alpha = .86), as was test–retest reliability (ICC = .89). Children with moderate-to-severe TBI, as well as children with mild TBI made significantly more errors in the Children's Cooking Task in comparison to controls (p< .001). The CCT was correlated with several tests and one questionnaire of executive functioning (Trails, verbal fluency, sorting, 20 questions, Dysexecutive Questionnaire).Discussion and Conclusion:The Children's Cooking Task has good interrater and test–retest reliability, as well as good discriminant and concurrent validity.

Purpose The purposes of this study were (a) to introduce “language access profiles” as a viable alternative construct to “communication mode” for describing experience with language input during early childhood for deaf and hard-of-hearing (DHH) children; (b) to describe the development of a new tool for measuring DHH children's language access profiles during infancy and toddlerhood; and (c) to evaluate the novelty, reliability, and validity of this tool. Method We adapted an existing retrospective parent report measure of early language experience (the Language Exposure Assessment Tool) to make it suitable for use with DHH populations. We administered the adapted instrument (DHH Language Exposure Assessment Tool [D-LEAT]) to the caregivers of 105 DHH children aged 12 years and younger. To measure convergent validity, we also administered another novel instrument: the Language Access Profile Tool. To measure test–retest reliability, half of the participants were interviewed again after 1 month. We identified groups of children with similar language access profiles by using hierarchical cluster analysis. Results The D-LEAT revealed DHH children's diverse experiences with access to language during infancy and toddlerhood. Cluster analysis groupings were markedly different from those derived from more traditional grouping rules (e.g., communication modes). Test–retest reliability was good, especially for the same-interviewer condition. Content, convergent, and face validity were strong. Conclusions To optimize DHH children's developmental potential, stakeholders who work at the individual and population levels would benefit from replacing communication mode with language access profiles. The D-LEAT is the first tool that aims to measure this novel construct. Despite limitations that future work aims to address, the present results demonstrate that the D-LEAT represents progress over the status quo.

In 1977, Shepherd and colleagues reported significant correlations (–.90, –.91) between speechreading scores and the latency of a selected negative peak (VN 130 measure) on the averaged visual electroencephalic wave form. The primary purpose of this current study was to examine the stability, or repeatability, of this relation between these cognitive and neurophysiologic measures over a period of several months and thus support its test-retest reliability. Repeated speechreading word and sentence scores were gathered during three test-retest sessions from each of 20 normal-hearing adults. An average of 56 days occurred from the end of one to the beginning of another speechreading sessions. During each of four other test-retest sessions, averaged visual electroencephalic responses (AVER s ) were evoked from each subject. An average of 49 clays intervened between AVER sessions. Product-moment correlations computed among repeated word scores and VN l30 measures ranged from –.61 to –.89. Based on these findings, it was concluded that the VN l30 measure of visual neural firing time is a reliable correlate of speech-reading in normal-hearing adults.
