ABSTRACT The Everyday Memory Questionnaire (EMQ) was developed as a subjective measure of memory failure in everyday life. Previous studies have investigated the factor structure of the EMQ in both healthy participants and people with multiple sclerosis (MS). The aim of the present study was to confirm the factor structure of the EMQ, to determine the internal consistency and criterion validity of the scale and to develop a shortened version.
A retrospective design, including participants from a study on MS patients and their carers and a study on stroke patients. Psychometric properties of the EMQ-28 were explored, and the measure was further revised from comparative analyses between the clinical and non-clinical groups.
Reliability and factor analysis of the EMQ-28 identified two main factors, general memory and attentional function, showing some concordance with previous research. Further analysis reduced the questionnaire to a 13-item measure (EMQ-R), with two main factors (Retrieval and Attentional tracking), strong internal reliability, and good discriminatory properties between clinical and control groups.
The 28-item questionnaire consistently differentiated between two broad systems of memory and attention, with some differentiation of visual and verbal, or language systems. Results showed some consistency with previous findings. The revised, 13-item questionnaire is a valid and reliable tool that has good face validity for use with neurological patients. Further exploration of the revised EMQ is recommended to provide information regarding its psychometric and clinical properties.

    ABSTRACT: A single case experimental design across behaviours was utilised to explore the effectiveness of Google Calendar text alerts delivered to a mobile phone as a memory aid. The participant was a 43-year-old man (JA) with severe memory problems and executive difficulties caused by a traumatic brain injury (TBI). JA was initially very unwilling to use any memory aid and so a detailed assessment of his beliefs about memory aids, his cognitive difficulties and his social context was performed and a set of specifications for an aid was produced collaboratively. Six weeks of baseline data and six weeks of intervention data were collected for three target memory behaviours and three control memory behaviours. Results were analysed using nonoverlap of all pairs (NAP) analysis which showed a reduction in forgetting in the three target behaviours and no change in two of the three control behaviours. A subjective measure (the revised Everyday Memory Questionnaire) also suggested improvement. This study illustrates that Google Calendar is a highly effective memory aid and emphasises the importance of choosing a memory aid to suit the person's lifestyle and beliefs.

    ABSTRACT: Background: With predicted increases in dementia incidence, interventions targeting neuroplasticity and neuroprotection are required. Cognitive training (CT) is an intervention which has been shown to improve aspects of cognition, but the pathophysiological mechanisms contributing to its efficacy are unknown. Objective: We aimed to explore the neurobiological correlates of CT using mismatch negativity (MMN), a neurophysiological marker of pre-attentive information processing, which in turn, is postulated to underpin higher-order cognitive processes. Methods: As part of a larger randomized controlled trial, forty 'at risk' (i.e., mild cognitive impairment or late-life depression) participants aged 51-79 years underwent neurophysiological, neuropsychological, and psychiatric assessments before and after a multi-faceted seven-week CT program or a 'treatment-as-usual' seven-week waitlist period. Results: The treatment group demonstrated significantly increased fronto-central MMN responses (p < 0.05), as well as improved phonemic verbal fluency (p < 0.05) and decreased self-rated memory difficulties (p < 0.05) following CT, in comparison to the waitlist control group. However, there were no significant correlations between enhanced MMN and cognitive/psychosocial outcomes. Conclusions: Results from this preliminary investigation indicate that CT is associated with enhanced neurophysiological mechanisms suggestive of improved pre-attentive processing, which may reflect alterations in underlying neurobiology. Further research is warranted to confirm these findings, to explicate whether CT is associated with restorative or compensatory neuroplastic processes and to determine whether MMN is a useful biomarker for treatment response.

    ABSTRACT: Uno de los instrumentos más utilizados para valorar los olvidos cotidianos es el Cuestionario de Fallos de Memoria de la Vida Cotidiana (MFE). El objetivo de este trabajo es estudiar la estructura factorial de una adaptación española del MFE y la relación de los factores tanto con el rendimiento en memoria objetiva como con variables de tipo afectivo en una muestra de 647 sujetos adultos (19-64 años). Para la evaluación se emplearon: MFE, Lista de Palabras y Escenas de Familia de la Escala de Memoria de Wechsler, Escala de Depresión y Ansiedad de Goldberg y dos preguntas sobre quejas de memoria. El estudio estadístico se realizó con los programas Mplus y SPSS. Los resultados mostraron la existencia de una estructura de tres factores, que explicaban el 29.3 % de la varianza: 1. Memoria relacionada con Actividades, 2. Reconocimiento y 3. Comunicación y Memoria de trabajo. Los dos factores con olvidos más frecuentes son Actividades y Comunicación, están más relacionados entre sí que con el de Reconocimiento y se relacionan más con aspectos afectivos y con las preguntas de quejas. La edad y el rendimiento objetivo de memoria se correlacionan más con el factor Reconocimiento.
