    ABSTRACT: Objectives.Little information is available regarding the extent of strategy use and factors that affect strategy use in amnestic mild cognitive impairment (aMCI). This study aimed to compare spontaneous strategy use and beliefs about the controllability of memory between aMCI and healthy older adult (HOA) samples and to explore the relationships between beliefs, strategy use, and memory performance for both groups.Method.The aMCI and HOA groups each composed of 60 individuals matched for age and education. The Memory Controllability Inventory was used to assess control beliefs, and the extent of semantic clustering on a list-learning task provided a measure of spontaneous strategy use. RESULTS: The aMCI group endorsed lower control beliefs and demonstrated poorer semantic clustering and memory performance compared with the HOA group. Although strategy use partially mediated the control beliefs-memory performance relationship for the HOA group, this was not replicated for the aMCI group.Discussion.Despite the weak relationship between control beliefs and strategy use, and control beliefs and memory performance for the aMCI group, the strong relationship between strategy use and memory performance provides impetus for further research into factors that can be used as a means of enhancing strategy use in interventions for aMCI.

    ABSTRACT: Despite the inclusion of memory strategy training in many interventions for amnestic mild cognitive impairment (aMCI), little research has directly examined knowledge and use of memory strategies in aMCI and their relationship to memory performance in order to guide the development of targeted interventions. The present study aimed to compare strategy knowledge and use between an aMCI and a healthy older adult (HOA) sample, and to determine the contribution of strategy knowledge and use to memory performance in each of these groups. The sample comprised 37 aMCI and 52 HOA participants aged over 60 years. All participants completed questionnaires to assess strategy knowledge and self-reported use of internal and external strategies in everyday life. In addition, strategy use was observed on the measures of retrospective and prospective memory performance (the CVLT-II and the CAMPROMPT). The aMCI group demonstrated decreased strategy knowledge and observed use of internal strategies, although equivalent observed use of external strategies compared with the HOA group. Furthermore, they reported equivalent use of both internal and external strategies. Observed use of strategies was significantly associated with retrospective memory performance for both groups and prospective memory performance for the aMCI group, supporting the inclusion of strategy training in interventions.
