Abstract:

Study examined the factor structure of the Everyday Memory Questionnaire (EMQ) in people with traumatic brain injury (TBI). A secondary analysis was conducted of baseline data from two clinical trials targeting memory impairment after TBI. Participants were 169 individuals with complicated mild, moderate, or severe TBI at an average of 41 months post-injury. They completed the EMQ via clinical interview. Exploratory factor analysis was conducted using a three-factor principal axis factoring estimation method with a polychoric correlation matrix and oblique rotation. Results indicated that three factors accounted for 49.2 percent of the variance, with moderate correlations observed among the factors. The identified three factors appeared to represent general everyday memory (prospective and episodic), conversational memory, and spatial or action memory. The three factors added significantly to the variance in age-corrected objective learning test scores predicted by injury severity, education, and sex. The three factors of the EMQ are consistent with the heterogeneity of memory impairments observed after TBI. The factor scores may be used to target treatments for impaired memory and to evaluate their effectiveness.
