Positive Neuropsychological Factors Associated With Greater Engagement in Brain Health Behaviors in Older Adults.

Research has examined the influence of positive psychological factors including purpose in life (PIL), need for cognition (NFC), and psychological flexibility on behaviors that support brain health (i.e., preserved cognitive functioning and brain structures).

Settling the Score: Can CPT-3 Embedded Validity Indicators Distinguish Between Credible and Non-Credible Responders Referred for ADHD and/or SLD?

Objective: The purpose of the present study was to further investigate the clinical utility of individual and composite indicators within the CPT-3 as embedded validity indicators (EVIs) given the discrepant findings of previous investigations.

Methods: A total of 201 adults undergoing psychoeducational evaluation for ADHD and/or Specific Learning Disorder (SLD) were divided into credible ( = 159) and non-credible ( = 42) groups based on five criterion measures.

Results: Receiver operating characteristic curves (ROC) revealed that 5/9 individual indicators and 2/4 composite indicators met minimally acceptable classification accuracy of ≥0.

Examining heterogeneity in depression symptoms and associations with cognition and everyday function in MCI.

Introduction: Although there is some evidence that different symptoms of depression have differential effects on cognition in older adults, these relationships remain understudied in older adults with mild cognitive impairment (MCI).

Method: Older adults (>50 years old) were classified as having MCI by Alzheimer's Disease Research Centers (ADRCs). Exploratory factor analyses and factor mixture modeling were used to determine depression symptom classes.

Validation of the National Alzheimer's Coordinating Center (NACC) Lewy Body Disease Module neuropsychological tests.

Introduction: This study assessed the construct validity and clinical utility of the National Alzheimer's Coordinating Center Lewy Body Dementia (LBD) Module, consisting of the Speeded Attention and Noise Pareidolia Tasks.

Methods: Participants included 459 older adults diagnosed as cognitively normal (n = 202), or with non-amnestic mild cognitive impairment (n = 61), amnestic mild cognitive impairment (n = 96), Alzheimer's disease dementia (n = 44), or LBD (n = 56).

Results: Speeded Attention demonstrated strong convergent validity and moderate discriminant validity when compared to established neuropsychological tests.
