Information for the IA can be obtained from the patient or from a caregiver. Each of the six questions for the three subscales is shown in Table 1. https://doi.org/10.1371/journal.pone.0169938.t005. Rationale and protocol of the ENGAGE study: a double-blind randomized controlled preference trial using a comprehensive cohort design to measure the effect of a cognitive and leisure-based intervention in older adults with a memory complaint. However, these measures were not perfectly correlated suggesting that there are also unique aspects of anhedonia not related to apathy. The exploratory-derived solutions were assessed by scree plot [23] and two absolute fit indices: Root Mean Square Error of Approximation (RMSEA) and Standardised Root Mean Square Residual (SRMR). ANOVA was used to examine differences among the four apathy-motivation subtypes on independent measures of depression, anhedonia and fatigue (Fig 4). As many apathy scales assess apathy as a unidimensional symptom, Radakovic et al. The Akaike Information Criterion (AIC) [34] and sample-size adjusted Bayesian Information Criterion (sBIC) [35] are descriptive fit indices with lower values indicating more optimal model fit. Please enable it to take advantage of the complete set of features! The three-factor structure of the 18-item AMI (Table 1) was confirmed, and had good model fit indices (RMSEA = 0.076 with 90% CI of 0.068–0.083, SRMR = 0.071, CFI = 0.83). Apathy was assessed using the 18-item clinician-rated Apathy Evaluation Scale (AES).15 The AES was only administered at 2011 and 2015, precluding an analysis of baseline AES scores. Robert P, Manera V, Derreumaux A, Ferrandez Y Montesino M, Leone E, Fabre R, Bourgeois J. J Med Internet Res. 18 items; 18-72 (higher scores reflect more apathy) Items are scored on 4-point Likert scale with descriptors for the “self” version (not at all true, slightly true, somewhat true, very true) and those for the clinician and informant version (not at all characteristic, slightly characteristic, somewhat characteristic, very characteristic). Most people (60.8%) were identified as ‘generally motivated’ with their group average on each AMI subscale being lower than the overall mean. Objective: Conversely, the AMI ES subscale was correlated with the DAS emotional subscale but not behavioural/cognitive initiation subscale. No, Is the Subject Area "Factor analysis" applicable to this article? Items from the clinical LARS that were deemed to be applicable to healthy people were also adapted. Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, United Kingdom, Yes Yes Parkinsonism Relat Disord. Furthermore, the 4- and 5-class models had the lowest AIC and BIC values. The items are rated on a 4‐point Likert scale from 1 (not at all characteristic) to 4 (very characteristic). In addition, individuals who were ‘emotionally apathetic’, ‘behaviourally/socially apathetic’ or ‘generally apathetic’ were significantly more anhedonic than those who were ‘generally motivated’. Two hand-scorable, carbonless test booklets (self and family) are available. This 46-item behavior rating scale is much easier and less time-consuming to administer than a neuropsychological test battery. The AES is an 18-item scale that measures apathy as a single construct. Participants completed the AMI to confirm the proposed three-factor structure. It also correlated positively with all three subscales of the DAS. 9 DOMAINS 4 Composite Subscales Everyday productivity Interests Taking initiative Novelty seeking Voluntary actions Emotional responses Concern Social life Self-awareness Intellectual Curiosity Emotion Action Initiation (AI) Self-Awareness (SA) TOTAL SCORE -36 (normal) to +36 (abnormal) Lille Apathy Rating Scale (LARS) Sockeel et al., 2006 Their emotional apathy evaluation scale subscales and lack of validated, standardised instruments for detecting apathy and motivation a of...
