11624 Background: Distress has a negative impact on medical treatment (Di Matteo, Lepper & Croghan, 2006) and it is considered one of the most important indexes of psychological suffering in oncological patients (NCCN, 2015). Thus, the purpose of this study was to determine the long term effectiveness of brief Cognitive Behavioral Therapy for patients with cancer (CBT-C) compared with a control group (CG) of oncological patients without any psychotherapy intervention - at one year after a chemotherapy treatment. Methods: Participants ( n = 80; mean age = 63.3, SD = 13.4; 54 female) enrolled at the Oncology Day Hospital at the “Presidio Ospedaliero” of Saronno, ASST Valle Olona, Italy who undertook (CBT-C: n = 40) or non-undertook (CG: n = 40) a psychotherapy intervention. Individual psychotherapy sessions strictly followed the IPOS guidelines (Watson & Kissane, 2017). Participants were tested with the Psychological distress Inventory (PDI) at the baseline (T1; Cronbach α = .88) at the end of the chemotherapy treatment (T2; Cronbach α = .87), at the end of the psychotherapy intervention (T3; Cronbach α = .88), 6-month follow-up (T4; Cronbach α = .85), and 1-year follow-up (T5; Cronbach α = .84). Results: Multilevel growth curve modeling – controlling for age, number of sessions, type and localization of tumor – showed a sharper reduction of distress for CBT-C participants that continue after posttreatment until 1-year follow-up ( p < .001); whereas for CG participants it reduced more gradually from pretreatment to 1-year follow-up ( p < .001). The results revealed a significant difference between the linear slopes for each treatment condition ( p < .001). The overall Hedges’ g comparing the two groups for distress reduction between pretreatment and 1-year follow-up was 2.14 (p < .001) in favor of CBT-C. Conclusions: Given that psychological distress occurs frequently among oncological patients this study is into an important area of study. Results suggest that CBT-C is statistically and clinically effective in treating psychological distress 1 year after the chemotherapy treatment. These findings revealed a kind of long-term effectiveness psychological intervention able both to reduce psychological suffering and improve a better quality of life in oncological settings.
