Figure 1. Percentage of Participants per PM Score depending on Groups of Age and Depressive Symptoms.

Note. This figure represents the distribution of participants per PM score for Young-Old (Y-O) and Old-Old (O-O) participants in lower and higher depressive symptoms groups.

Note. This table shows the means, standard deviations and range of age, depressive symptoms, memory self-efficacy (MSE), education, Mini-Mental State Examination (MMSE) and prospective memory (PM) for each age, depressive symptoms and metamemory groups (“Young-Old” vs “Old-Old” adults and “Higher Depressive Symptoms” vs “Lower Depressive Symptoms” and “Lower MSE” vs “Higher MSE” groups).

Figure 2. Representation of the 3-way Interaction between Depressive Symptoms, Age, and MSE on PM Performance.

Note. This figure represents the 3-way interaction between depressive symptoms, age, and memory self-efficacy on the prospective memory performance (error bars represent standard errors). “Y-O” and “O-O” respectively represent the Young-Old and Old-Old participants, while “Higher MSE” and “Lower MSE” respectively refer to higher and lower metamemory groups of participants. Numbers in brackets represent the 95% confidence interval of the posterior distribution for each respective comparison, while * indicates significant differences.
