[Intervention focused on resources to reduce anxiety and depression disorders in cancer patients: A pilot study].

Abstract

INTRODUCTION\nCancer, a widespread chronic disease, represented 400,000 diagnoses in France in 2017. The diagnoses as well as the treatments are a major source of stress for most patients concerned. Secondary effects may be painful and disturbing (pain, nausea, fatigue, loss of social and/or professional status, anxiety of death), and may lead to maladaptive coping strategies (avoidant coping), psychological inflexibility, anxiety, depression, and suicide risks which are twice as important as in the general population. Research in the field of psychotherapy for cancer patients represents an important international target, in particular in what concerns enhanced patient quality of life during and after treatment. Cognitive Behavioral Therapy, Mindfulness-Based Stress Reduction, as well as adapted physical activity have shown promising results to enhance patients quality of life at different stages of the process. However, results mainly show significant short-term effects and usually only for patients with high levels of anxiety and depression symptoms. With the development of third wave Cognitive Behavioral Therapy, more global interventions (not just aimed at anxiety and depression symptoms) have emerged. Research has underlined their efficacy on both symptom reduction (anxiety and depression) and quality of life enhancement through the development of more varied and adaptive responses to stressful situations. Positive psychology interventions, mindfulness, and Acceptance and Commitment Therapy have inspired third wave Cognitive Behavioral Therapy. Emotional acceptance, mindful awareness of thoughts and emotions, and engaging in actions that are coherent with one s values all form part of the means by which these interventions may help patients to find ways to better adjust to their stressful situation. The results of the efficacy trials carried out using these approaches were mixed, and effects were mainly modest. Furthermore, most of the studies only tested one approach at a time, while each approach activated mechanisms, which can be useful for these patients. Hence, the aim of the current study was to test an integrative program based on classical second wave Cognitive Behavioral Therapy as well as on practices from the third wave of Cognitive Behavioral Therapy. We aimed at carrying out a preliminary study assessing the potential effects of the program on cancer patients anxiety, depression symptoms, well-being and psychological flexibility.\n\n\nMETHOD\nSixteen cancer patients were enrolled in a second and third wave Cognitive Behavioral Therapy workshop composed of six sessions. In-session practices were based on validated practices. Participants completed the following questionnaires before the first workshop (T1) and at the end of the sessions (T2) in order to assess anxiety, depression symptoms, well-being and psychological flexibility: HAD, WEMWBS, MPFI, AAQ-2. Qualitative data regarding acceptability were also collected at the end of the last session.\n\n\nRESULTS\nAmong the sixteen participants, nine women (mean age=56.1years old) completed the questionnaires seven of whom had breast cancer. The results of this preliminary study showed a significant pre-to-post reduction in anxiety and depression symptoms (P=0.017) as well as on certain dimensions of psychological flexibility: reduced self as content (P=0.011), and enhanced cognitive diffusion (P=0.018). Only marginal differences were found on other dimensions: reduced inaction (P=0.074) and experiential avoidance (P=0.089), and enhanced self as context (P=0.062). Content analysis showed (1) increased positive perceptions about experiences with more serenity, (2) positive attitudes towards self (self-compassion), (3) enhanced positive relationships, and (4) ability to accept negative affect.\n\n\nCONCLUSION\nPatients qualitative feedback highlighted the potential feasibility and adaptability of the program for this population. The results of this preliminary study show promising avenues for research in the field of cancer patients adaptive coping enhancement as well as reduce anxiety and depression symptoms. This type of workshop can be considered as complementary to individual psychotherapies as they may tap into different mechanisms that help foster psychological flexibility as the group format enhances decentering processes. Further research avenues are proposed in order to assess the efficacy of such interventions in cancer patients compared to other types of interventions. Further research should also look into individual differences in order to orient patients towards practices that fit them best.
