Resum:	Background and objectives: Healthy people with intact cognitive functioning may also experience subjective cognitive deficits (SCD). However, no study has thoroughly explored these symptoms in healthy Spaniards. Therefore, we aimed to: (i) describe the pattern of SCD in this population, (ii) report magnitude categories of SCD, and (iii) correlate SCD with age, gender and years of education. Methods: 102 healthy Spaniards (51 men) were recruited. Men and women subgroups were matched by age and years of education. SCD were evaluated using the 20-item Perceived Deficits Questionnaire (PDQ-20). Magnitude categories of SCD were described as distribution-based quartiles of the total PDQ-20 score, with higher scores/quartiles indicating greater SCD. Participants with a total PDQ-20 score greater than 2 standard deviations (SD) above normal variation were considered at risk of clinically significant SCD. Results: Mean total PDQ-20 score was 17. 98 (SD = 8. 29), with higher scores on "Attention/Concentration" and "Retrospective Memory" subscales than on "Planning/Organization" and "Prospective Memory" subscales. Total PDQ-20 score distribution by quartile was: 0-11 (1 quartile), 12-17 (2 quartile), 18-23 (3 quartile) and 24-80 (4 quartile). Only 1. 96% of participants were at risk of clinically significant SCD. There was a marginal trend in the association between age and "Retrospective Memory" subscale (r = 0. 256; p = 0. 009). Conclusions: Our findings may help health professionals interpret PDQ-20 scores more accurately in clinical settings. A total PDQ-20 score equal or greater to 35 may be a valid threshold for identifying people at risk of clinically significant SCD. Assessment of SCD may improve the ecological validity of research on human cognition.
