Beyond Uniform Impairment: Investigating Declarative Memory Profiles in Nonspecific Mild Intellectual Disability Using Latent Profile Analysis.

ABSTRACT:

Background

Significant memory impairments are consistently observed in individuals with intellectual disabilities (ID), but considerable variability exists. This study investigated the heterogeneity of declarative memory in children and adolescents with nonspecific mild intellectual disability (NSID) to identify distinct memory profiles and potential predictors of this disability.

Methods

A latent profile analysis (LPA) was conducted on a large sample (N = 999, including 114 with NSID) using six supplementary memory indices from the Test of Memory and Learning-Second Edition (TOMAL-2). A logistic regression analysis subsequently examined the predictive power of TOMAL-2 indices for NSID diagnosis.

Results

LPA revealed two distinct memory profiles: a 'memory impaired gr
