Development of the Brief Assessment of Prospective Memory (BAPM) for use with traumatic brain injury populations

Impairment of prospective memory (PM) is a common problem following traumatic brain injury (TBI) which can affect functional outcomes. PM failures in everyday life can be assessed using self-report questionnaires; however, existing measures tend to be lengthy, which may be problematic for individuals with fatigue and other cognitive impairments. This study aimed to develop a short form of the Comprehensive Assessment of Prospective Memory (CAPM) and examine its psychometric properties. Using theoretical and statistical considerations, the number of items on the CAPM was reduced to 16 including equal numbers representing the basic activities of daily living (BADL) and instrumental activities of daily living (IADL) subscales. The psychometric properties of the new measure, named the Brief Assessment of Prospective Memory (BAPM), were examined by secondary analysis of data from two samples of community dwelling adults (aged 17 to 91 years, n = 527, and 15 to 60 years, n = 95) with no history of brain injury, and a sample of rehabilitation patients with moderate to severe TBI (n = 45). Results indicate that the BAPM has a robust factor structure, strong agreement with the original CAPM, acceptable internal consistency and test-retest reliability, and evidence of criterion-related validity with psychosocial integration as the point of reference for people with TBI.

Remembering to age successfully: evaluation of a successful aging approach to memory enhancement.

BACKGROUND Memory enhancement programs that can significantly improve actual memory performance and subjective perceptions of everyday memory in elderly people are rare. This study was designed to evaluate a new memory enhancement program incorporating principles of successful aging, designed to enhance subjective and objective everyday memory in community-dwelling old people. METHODS Two matched groups of 20 healthy community-dwelling elderly adults were assessed on measures of objective and subjective memory performance before and after participating in a memory enhancement or active control condition. RESULTS Planned multivariate analysis of variance (MANOVA) on change scores showed that participants in the memory enhancement program improved significantly on both objective and subjective measures. Specifically, greater improvement was demonstrated on a verbal paired associates task, story recall, face recognition, contentment with memory, and use of memory strategies. CONCLUSIONS Although a fully randomized design was not used, the results are promising, suggesting that memory training incorporating principles of successful aging can enhance memory performance in healthy old people, objectively and subjectively.

Effects of aging, planning, and interruption on complex prospective memory

This study examined the effects of aging, planning, and interruption on complex prospective memory (PM) using a 2 x 2 x 2 between-subjects design. Participants were 80 younger adults (65 females) aged 18–33 years and 80 older adults (70 females) aged 60–75 years. They were randomly allocated to four conditions (viz., no interruption and no planning, interruption but no planning, planning but no interruption, and both planning and interruption) and asked to undertake three PM tasks (time-, event-, and activity-based) while performing an ongoing task (viz., recipe checking and identification) in a simulated home environment. Younger adults were found to perform significantly better than older adults on time- and event-based PM. The opportunity to plan for five minutes was found to improve performances on all three types of PM. Unexpected, external interruptions, on the other hand, were found to reduce performance for time-based PM. Interestingly, planning was found to significantly improve the performance of older adults on time-based PM and to a level similar to that of younger adults. Results of the study have clarified the independent and interactive effects of the three variables on PM and have implications for understanding and enhancing this type of memory.

Stress, achievement, marriage and social support: Effects on the psychological well-being of physicians entering midlife/mid-career

Abstract The major aim of this study was to examine the relative contribution of stress, professional achievement, personality, quality of marriage and family life, social support satisfaction, work satisfaction, average hours worked and family responsibilities to the psychological well-being (life satisfaction and psychological symptoms) of medical practitioners entering mid-life/mid-career. Fifty-nine female and 57 male physicians completed interviews, questionnaires, and daily stress records. The results confirm the central role that stress plays in the well-being of physicians. Pearson correlations and hierarchical multiple regressions showed other major variables examined did not explain additional variance in psychological symptoms, but did in some instances (professional achievement, quality of marriage, social support satisfaction for work issues) contribute to life satisfaction. A path model indicating a direct and independent effect of professional achievement on life satisfaction and a specific...

Assessing accuracy of knowledge of cognitive effects of normal ageing and mild stage of Alzheimer's disease

Objectives: This study aimed to develop and pilot the Alzheimers Disease and Ageing Perception Scale (ADAPS), examine theory-consistent differences and convergent validity, and identify misconceptions of the cognitive effects of ageing and mild Alzheimers disease (AD). Method: After piloting a large pool of items with a panel of ageing and dementia experts (n = 6), an item analysis yielded a 25-item version of the ADAPS (α = .70), comprising a Normal Ageing subscale (α = .68) and Mild AD subscale (α = .74). Participants from the general community (n = 251) and aged care professionals (n = 59) completed the ADAPS, Knowledge of Memory Ageing Questionnaire (KMAQ), and the Alzheimers Disease Knowledge Scale (ADKS). Results: Compared to matched controls, aged care professionals demonstrated greater accuracy of knowledge on the Mild AD subscale (p < .05), but not the Normal Ageing subscale (p > .05) of the ADAPS. The pattern of significant correlations between the ADAPS, KMAQ, and ADKS supported the convergent validity of the ADAPS. The most common misconceptions on the ADAPS indicated a tendency for participants to overgeneralise the cognitive effects of normal ageing. Conclusion: This preliminary study introduces a new tool for assessing accuracy of knowledge of cognitive effects associated with normal ageing and mild AD, and may assist in identifying misconceptions of the ageing process.

Prospective memory assessment for persons with traumatic brain injury

Endogenous free radical production by NADPH oxidase 2 contributes to the secondary injury cascade after traumatic brain injury in miceAccepted Abstracts from the International Brain Injury Association’s Ninth World Congress on Brain InjuryObjectives: Studies have shown that occupational therapy interventions for clients with cognitive impairment following acquired brain injury (CIABI) have a positive effect on performance of activities of daily living, although the exact nature of the interventions are not clearly described. A better understanding of current practice is therefore needed to move further in the search for evidence based occupational therapy for clients with CIABI. Research on occupational therapists’ (OTs’) practice can play an important role to explore and describe current practice and furthermore define and evaluate the effectiveness of different components in OT interventions. The aim of this study was to survey Swedish OTs’ practice patterns for clients having CIABI.Methods: The study had a cross-sectional design using a questionnaire developed in two former studies. A stratified random sample was done with 250 OTs each from the following areas: regional care, somatic county care, primary care and municipal eldercare. The questionnaire was sent out using on-line survey software and 462 participants responded. Data is currently analyzed by descriptive and comparative statistics.Results: Preliminary results show that the interventions targeted a wide range of cognitive impairments and its consequences. Interventions were both remedial and compensatory with graded activity as the most common remediating intervention. To compensate for activity limitations prescription, or recommendation, of assistive devices (AD) as well as supporting clients in finding internal strategies were used extensively. The ADs used consisted of both high and low technology devices. Eighty-two percent also included different specific interventions to improve clients’ decreased self-awareness in their practice. A vast majority of the OTs (94%) preferred to use observations in daily activities to assess both activity limitations and cognitive impairment. Almost all participants also used interviews and sixty-two percent used tests on impairment level. To support practice general Occupational Therapy models were widely used while theories focusing on cognitive impairments specifically were used less. The participants’ answers reflected a client-centered attitude with collaborative goal-setting and feedback discussions after each session. Eighty- four percent felt dependent on relatives to reach a successful outcome and most of them worked deliberately to involve relatives in the rehabilitation. The OTs responses were evenly distributed over the spheres of activity. Ninety-two percent of the participants worked in team and the most common diagnoses were stroke and traumatic brain injury. There were some differences in responses between the spheres.Conclusions: Preliminary conclusions are that the OTs practice patterns included interventions targeting most cognitive impairments and their consequences in daily activities. The use of daily activities as a mean was preferred irrespective of whether the interventions were remediative or compensatory. Interventions targeting decreased self-awareness as well as the use of ADs were common. A client-centered approach was dominating including collaboration with relatives.For personalcentered approach was dominating including collaborationwith relatives.Diagnosis of Disorders of Consciousness : Evoked Potentials and Behavioural Assessment in clinical practice
