Abstract
BACKGROUND: The characteristics of subjective memory and the underlying cause of subjective memory complaints are well-established in the older population, but less is known about memory functioning and self-perceived memory deficiency in young adults. Therefore, we aimed to investigate the potential contributing factors of subjective memory complaints in young adults, such as objective cognitive performance, negative affective state, well-being and subjective sleep quality. METHODS: 125 participants over the age of 18 years were recruited in the study (average age was 21 years (SD = 2.29), 58 males and 67 females, average education of the participants was 14.1 years (SD = 1.94). We measured subjective memory with Multifactorial Memory Questionnaire and different cognitive domains (such as short- and long-term verbal and visual memory, working memory, and executive functions), negative affective states (depression and anxiety), well-being, and subjective sleep quality. RESULTS: Our results showed that depression had a significant predictive value on satisfaction with memory and subjective memory complaints. We failed to find a relationship between perceived subjective memory functioning and objective cognitive performance. Besides anxiety, only the executive functions predicted significantly the frequency of internal strategy use. CONCLUSION: In conclusion, we revealed that negative affective states are more pronounced in the satisfaction with memory and subjective memory complaints in young adults than the objective cognitive ability.
