Desafios enfrentados e lições aprendidas: Um programa de treinamento de memória prospectiva de vários componentes para adultos idosos da Malásia

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

As circunstâncias e ambientes circundantes de adultos idosos da Malásia poderiam tornar a condução da intervenção (principalmente em termos de ensaios clínicos ou randomizados controlados) um desafio. Trabalhar com adultos mais velhos e enfrentar problemas culturais pode ser instigante.

Objetivo:

Este artigo ilustra uma perspectiva significativa de alguns dos desafios enfrentados durante a realização de um estudo controlado randomizado que explora o impacto de uma intervenção de múltiplos componentes, incluindo treinamento de memória prospectiva baseado em estratégia e processo (PM) entre idosos da Malásia.

Métodos:

Como o estudo atual foi um ensaio clínico randomizado (ECR), os desafios foram apresentados de acordo com o estilo de declaração CONSORT.

Resultados:

Uma discussão sobre como essas questões foram abordadas é fornecida.

Conclusão:

Algumas sugestões foram apresentadas para ajudar os pesquisadores a planejar e criar intervenções para estudos semelhantes e capacitar um método prático para abordar todos os desafios relacionados.

Study stage	Description
Design	•RCT within-participants cross-over design including a multi-component intervention including strategy- and process-based (computer-based) components. •The study included two conditions: treatment/training and no-contact control conditions. •Ethical approval was sought from the University Putra Malaysia (UPM) ethics committee.
Sample	•40 potential participants were contacted, however only 25 were assessed for being eligible, and formally enrolled into the study based on the inclusion criteria: 1. subjects must be 55 years old and above, 2. educational level must be at least secondary level, and 3. show absence of; [i] history of neurological impairments (measured with MMSE (cut-off value=27) where scores for the sample ranged from 27 to 29 (M=27.68, SD=0.75), [ii] any major psychiatric disorder (taking any psychoactive medication (e.g., anti-depressive)) and learning disabilities, [iii] history of general anaesthesia, head traumas (in the last 6 months prior to the study), cerebrovascular disease, or neurological impairments, and [iv] drug/alcohol abuse. •Informed consents were collected from the participants.
Setting	•The sample was collected from the U3A Kuala Lumpur/Selangor active members, their family members and friends. •The intervention was conducted in the computer lab of the Faculty of Human Ecology, University Putra Malaysia (UPM).
Intervention	•Each intervention session lasted 2 hours. •There was 1 session per week for 6 weeks. •During each session, participants were exposed to intention implementation and other similar strategy-based exercises and a computer-based exercise (playing Virtual Week).
Data collection	•Baseline and post-intervention assessments for 4 outcome measures were assessed: PM (PRMQ and PM-Tasks^* * Prospective Memory-Tasks (PM-Tasks) is a computerized measurement tool developed to evaluate three types of PM tasks (event-based, time-based, and activity-based PM tasks). In the eventbased PM tasks section, a sequence of pictures including four shapes in each picture is presented at the center of the screen, and the participants are required to decide by pressing different keys for different shapes. If there is a bold and white shape in any sequence they are asked to press the spacebar (this is the PM task). In total, five bold and white shapes will be presented. In the time-based PM tasks section, everything is the same as the previous section except that a digital timer appears in the upper part of the screen. Each time the timer turns another full minute (e.g., 02:00, the last two digits are 00), participants are required to press the spacebar (PM task). Moreover, no bold and white shapes appear on the screen. The score ranges from 0 to 5 for this part. At the end of each part of the test, participants see a written phrase displayed on the screen and are asked to press “enter” upon seeing this phrase (activity-based PM task). ), IADL, GDS, and GAS
Data analysis	•Results of pre- and post-test assessments were reported as means (M), and standard deviations (SD). The General Linear Model (GLM) was used to show the effectiveness of the intervention.
