Abstract

Rastući udio starijeg stanovništva te kognitivno slabljenje povezano sa starenjem dovelo je do porasta broja programa i intervencija namijenjenih kognitivnom osnaživanju u starijoj dobi. Na tržištu je dostupan veliki broj kompjuteriziranih intervencija, no još uvijek izostaje jednoznačan odgovor na pitanje njihove učinkovitosti. Stoga je cilj ovog sustavnog pregleda i meta-analize randomiziranih kontroliranih istraživanja ispitati učinkovitost kompjuteriziranih kognitivnih treninga (CCT) i nekih njihovih karakteristika (npr. trajanje treninga, način provedbe) u poboljšanju kognitivnog funkcioniranja zdravih odraslih osoba. U ispitivanje je uključeno 12 primarnih istraživanja koja su zadovoljavala postavljene kriterije. Provedbom analize u okviru modela slučajnih učinaka utvrđena je mala veličina učinka (kao mjeru učinka koristimo Hedgesov g) koja iznosi .339 sa srednjom heterogenosti. Moderacijskim analizama ovih podataka zaključujemo da trajanje treninga ne predstavlja značajan medijator učinkovitosti kognitivnog treninga, ali uočljiv je trend veće učinkovitosti treninga koji se odvijaju pod nadzorom u odnosu na treninge provedene u domovima sudionika. Iako rezultati upućuju na mali učinak CCT-a, ističu važnost istraživanja specifičnih uvjeta koji doprinose njihovoj učinkovitosti. Također sustavni pregled upućuje na nužnost standardiziranja metoda istraživanja i izvještavanja u svrhu promicanja ovog područja i implementacije samih CCT.

Abstract (english)

The increasing share of aging population and age-related cognitive decline have led to an increasing number of cognitive enhacement interventions for elderly. A large number of commercially available computerized interventions have found their place on the market, but researchers still do not have a clear answer to the question of their efficacy. Therefore, the aim of this systematic review and meta-analysis of randomized controlled studies was to examine the efficacy of computerized cognitive trainings (CCT) in improving cognitive performance of healthy older adults and to examine how the characteristics of CCT (e.g., the length or nature of training) are related to its efficacy. Twelve primary studies were found that met the criteria and were included in the final analysis. The analysis performed within the random effects model estimated a small effect size (calculated using Hedges' g) of .339 with moderate heterogeneity. A moderation analysis found the length of training as an insignificant mediator. Although statistically insignificant, a trend of greater efficacy of supervised trainings is found. Even though we found a small effect of the efficacy of CCT, additonal research on conditions contributng to its effectiveness is advised. The results of the systematic literature review highlight the need to standardize the study paradigm and reporting methods in order to systematically develop this field of research and its implementation.
