Dynamic neurocognitive adaptation in aging: Development and validation of a new scale.

ABSTRACT:

Introduction

Forty-five percent of Alzheimer's disease (AD) cases may have been preventable through protective factors. Reserve, resilience, and resistance share common neurocognitive adaptive processes, acting through protective mechanisms. In this article we propose the development and validation of a new scale, called dynamic Neurocognitive Adaptation, developed in this direction.

Methods

We included 815 participants (50% women; 65+ years inclusive of age), divided into two subsamples for exploratory and confirmatory factor analysis. Our initial scale was composed of 30 items, investigating seven dimensions, explored by a 5-point Likert scale reflecting the frequency of activities, for seven time windows.

Results

Our final scale had 20 items divided among four dime
