Piloting CanCope: An internet-delivered transdiagnostic intervention to improve mental health in cancer survivors

Targeting emotional regulation using an Internet-delivered psychological intervention for cancer survivors: A randomized controlled trial

OBJECTIVES

This trial assessed the efficacy of an emotion-focused, modular, Internet-delivered adaptation of the Unified Protocol (UP) in improving cancer survivors' emotion regulation strategies.

DESIGN

A two-arm randomized controlled trial (1:1) was used to compare the efficacy of two Internet-based interventions: UP-adapted CanCope Mind (CM) and lifestyle-focused active control CanCope Lifestyle (CL).

METHODS

N = 224 cancer survivors randomized to CM or CL were assessed at baseline, between-modules, at post-intervention and 3-month follow-up on emotion regulation outcomes targeted by each CM module (Module 1: beliefs about emotions; Module 2: mindfulness; Module 3: cognitive reappraisal skills, catastrophizing, refocus on planning; Module 4: experiential avoidance). Primary analyses were intention-to-treat linear regressions using Fisher randomization tests for p-values and intervals were used to compare groups with standardized mean difference (SMD) effect sizes.

RESULTS

CanCope Mind participants (n = 61 completers) experienced moderate-to-large improvements (SMDs from .44-.88) across all outcomes at post-intervention. CM's effects were larger than CL's (n = 75 completers) immediately post-intervention and at 3-month follow-up for beliefs about emotions, mindfulness, cognitive reappraisals and experiential avoidance (all p's < .05). CM experienced greater improvements in catastrophizing immediately post-intervention, with a trending effect at follow-up. However, we could not reject the null hypothesis of identical between-group effects for refocusing on planning both immediately post-intervention and at follow-up. Exploratory analyses revealed inconsistent between-module effects.

CONCLUSIONS

In its entirety, CM is a promising intervention for improving and maintaining cancer survivors' adaptive emotion regulation, especially for mindfulness and experiential avoidance. This may have important clinical implications for promoting cancer survivors' emotional functioning and general well-being.

Which symptom to address in psychological treatment for cancer survivors when fear of cancer recurrence, depressive symptoms, and cancer-related fatigue co-occur? Exploring the level of agreement between three systematic approaches to select the focus of treatment

PURPOSE

To investigate the extent to which three systematic approaches for prioritizing symptoms lead to similar treatment advices in cancer survivors with co-occurring fear of cancer recurrence, depressive symptoms, and/or cancer-related fatigue.

METHODS

Psychological treatment advices were was based on three approaches: patient preference, symptom severity, and temporal precedence of symptoms based on ecological momentary assessments. The level of agreement was calculated according to the Kappa statistic.

RESULTS

Overall, we found limited agreement between the three approaches. Pairwise comparison showed moderate agreement between patient preference and symptom severity. Most patients preferred treatment for fatigue. Treatment for fear of cancer recurrence was mostly indicated when based on symptom severity. Agreement between temporal precedence and the other approaches was slight. A clear treatment advice based on temporal precedence was possible in 57% of cases. In cases where it was possible, all symptoms were about equally likely to be indicated.

CONCLUSIONS

The three approaches lead to different treatment advices. Future research should determine how the approaches are related to treatment outcome. We propose to discuss the results of each approach in a shared decision-making process to make a well-informed and personalized decision with regard to which symptom to target in psychological treatment.

IMPLICATIONS FOR CANCER SURVIVORS

This study contributes to the development of systematic approaches for selecting the focus of psychological treatment in cancer survivors with co-occurring symptoms by providing and comparing three different systematic approaches for prioritizing symptoms.

Assessing an Internet-Delivered, Emotion-Focused Intervention Compared With a Healthy Lifestyle Active Control Intervention in Improving Mental Health in Cancer Survivors: Protocol for a Randomized Controlled Trial

BACKGROUND

Cancer survivors are vulnerable to experiencing symptoms of anxiety and depression and may benefit from accessible interventions focused on improving emotion regulation. CanCope Mind (CM) was developed as an internet-delivered intervention adapted from the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders to improve emotion regulation and support the mental health of cancer survivors.

OBJECTIVE

This protocol aims to provide an outline of the CanCope Study, a trial comparing the efficacy of a Unified Protocol-adapted internet-delivered intervention (CM) designed for cancer survivors compared with an active control condition-an internet-delivered healthy lifestyle intervention, CanCope Lifestyle (CL). The primary aim is to assess and compare the efficacy of both interventions in improving emotion regulation, anxiety and depressive symptoms, and quality of life. The secondary aims involve assessing the mechanisms of the CM intervention.

METHODS

This trial is a 2-arm randomized controlled trial that allocates cancer survivors to either CM or CL. Both interventions comprise 4 web-based modules and are expected to take participants at least 8 weeks to complete. Participants' mental and physical health will be assessed via self-reported surveys at baseline (T0), between each module (T1, T2, and T3), immediately after the intervention (T4), and at 3-month follow-up (T5). The study aims to recruit 110 participants who have completed T4.

RESULTS

The CanCope study began recruitment in September 2020. A total of 224 participants have been randomized to the CM (n=110, 49.1%) and CL (n=114, 50.9%) groups.

CONCLUSIONS

This is one of the first trials to develop and investigate the efficacy of a web-based intervention for cancer survivors that specifically targets emotion regulation.
