Background/Objectives: Thalassemia significantly affects the mental well-being and lifestyle of patients and their families. This study evaluated the temporal changes in quality of life (QoL) and psychological burden among thalassemia patients in 2025 and in relation to 2018. Methods: Two cross-sectional samples of patients (n = 236) were recruited during 2025 (n
1 = 117) and 2018 (n
2 = 119) at the Thalassemia Units on Crete/Greece. The EQ-5D-3L Quality of Life Scale, the EQ VAS Index, and the Hospital Anxiety and Depression Scale (HADS) were used through multiple logistic regression analysis to assess relative parameters. Results: High mean Health Status (EQ VAS Index) and QoL scores remained consistent from 2018 to 2025, anxiety mean levels were low and remained consistent from 2018 to 2025, depression levels were low but higher in 2025 in relation to 2018 (
p = 0.041), anxiety significantly exceeded depression in both 2018 and 2025, better QoL was associated with improved health status and reduced anxiety and depression, and individuals with children exhibited significantly lower odds of experiencing low or moderate QoL. Conversely, each unit increase in the Anxiety score significantly increased the odds of low or moderate QoL (OR = 1.26,
p = 0.002). Similarly, each unit improvement in health status significantly reduced the odds of low or moderate QoL (OR = 0.97,
p = 0.009). Conclusions: Health status and QoL remained consistent from 2018 to 2025, while depression levels increased. Anxiety significantly exceeded depression, and better QoL was associated with improved health status and reduced anxiety and depression.
