Abstract

A cognitive assessment is not complete without an inspection of a client’s emotional status. The Emotion Word Fluency Test (EWFT) is a newly developed instrument for Indonesia. It provides similar assessment to other semantic word fluency tasks, linguistic and memory skills, and also a client’s current emotional standing and previously experienced emotions. Our study aims to present the newly-developed EWFT and its scoring system, and the psychometric properties of the test including its test-retest reliability and construct validity, as well as the reliability of the scoring system. Healthy participants with no history of brain-related diseases (n = 98), varying in age and education, were recruited; an additional group (n = 30) was included in the test-retest reliability study. The construct validity was evaluated with a phonemic verbal fluency test (pVFT). The EWFT was correlated (.51-.56) with the pVFT, and the three subscales of the pVFT correlated highly (.75-.80), indicating that the EWFT and pVFT share a common construct, but are also different. The scoring system showed excellent reliability (.86 for the number of correct generated words), and the test-retest reliability for the number of correct words was moderate (.54). Participants produced more negative than positive emotion words, t(29) = 6.33, p < .05. The correlation between the number of positive and negative emotion words was zero. Age affected the performance in both EWFT, F(3, 80) = 3.10, p < .05; and pVFT F(3, 80) = 2.47, p < .05; as was internationally reported. The EWFT scoring system is concluded reliable and the test has moderate reliability.

Abstract

Difficulties in executive function (EF) may be causative factors in clinical conditions, including learning disabilities, depression, and anxiety. However, defining the structure of EF is an ongoing issue, although Miyake’s three-factor structure is widely accepted. This study aims to discover the underlying factor structure of EF domains, as measured by five tests and the scores of 840 participants, to establish the domains’ validity and reliability. Five neuropsychological tests were included in the exploratory and confirmatory factor analyses (EFA and CFA): the Digit Span (DS); the Stroop Color Word Test (Stroop Test); the phonemic Verbal Fluency Test (pVFT); the Five Point Test (5PT); and the Trail Making Test (TMT). EFA could be meaningfully performed (KMO = .862, Bartlett’s test: ????2 =1393.169, df 45, p < .001) and yielded three factors closely mirroring the three core domains of EF. CFA of the model in which the 5PT loaded on factor 2 showed the best goodness of fit indicators, although the difference with the other three-factor models was small. Currently, these EF tests are available in Indonesia and suitable for use, although obtaining normative scores adjusted for demographic factors is necessary.

Abstract

The number of correctly produced words is the primary output variable n most verbal fluency tests. The examination of the number of clusters and cluster size achieves a more in-depth analyses of cognitive aspects and processes. We propose a scoring system for phonemic, semantic, and emotion word fluency tests in the Indonesian context. This study aimed to determine the underlying cognitive constructs of the participants, including the clustering and switching indices, using principal component analysis (PCA). A total of 150 participants were included, and the tests were administered online following a previously validated protocol. The three fluency tests loaded different factors, and the loading clustering patterns varied among the tests. Regression analyses confirmed that both cluster size and the number of switches predicted the number of correct words, although this relationship differed between semantic and phonemic tests. The number of switches and cluster size interrater reliability for all three tests exceeded 0.90. The cluster size and the number of switches were suitable additional variables for scoring Indonesian phonemic, emotion, and animal names as semantic word fluency tasks. This approach allows for a more in-depth analysis of cognitive styles in clients undergoing neuropsychological assessment.
