Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A sequential multiple-assignment randomized controlled trial (SMART) will be used to assess the effect of an adaptive stepped-care intervention on FCR in cancer survivors with subclinical levels of fear of cancer recurrence.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The current SMART trial aims to address the following hypotheses:

Hypothesis 1: It is better to begin adaptive interventions with eConquerFear than with eHealthMaintenance.

Hypothesis 2: Among initial non-respondents, it is better to switch to supervised, face-to-face ConquerFear than to augment eConquerFear with eHealthMaintenance.

Hypothesis 3: eConquerFear + ConquerFear will lead to the greatest reduction in fear of cancer recurrence.

Hypothesis 4: There would be an indirect effect of stepped-care ConquerFear intervention on fear of cancer recurrence through its effect on maladaptive metacognition and cognitive attentional syndrome.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

SEQUENTIAL

First stage intervention: We will use a block randomization with randomly permuted block sizes of 2,4, and 6 to ensure close balance of the numbers in each arm. Participants will be randomised to the eConquerFear or eHealthMaintenance

Second stage intervention for non-respondents: We will use a block randomization with randomly permuted block sizes of 2,4, and 6 to ensure close balance of the numbers in each arm. Participants will be randomised to the augment eConquerFear with eHealthMaintenance (or vice versa) versus switch to supervised, face-to-face ConquerFear intervention.
Primary Study Purpose

TREATMENT

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
he investigator, care provider, investigator and outcomes assessor are masked in terms of not knowing to which condition the participants will be randomized until after the completion of the baseline assessment. The outcomes assessor will break the envelope for the next eligible participant indicating if that participant is to be allocated to intervention or control arms.

The participants are masked in terms of not knowing that one intervention is hypothesized to yield larger effects than the other.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

First stage intervention: eConquerFear

Participants in the eConquerFear intervention group will receive six online modules with each containing educational text, illustrative graphics, interactive exercises, and brief videos. Every module will teach a specific topic, such as self-examination and medical surveillance, values-based goal setting, attention training, detached mindfulness, worry management and treatment summary and relapse prevention.

Group Type EXPERIMENTAL

eConquerFear

Intervention Type BEHAVIORAL

The key goals of this e-intervention are to: (i) teach strategies for controlling worry and excessive threat monitoring; (ii) modify underlying unhelpful MCQ beliefs about worry; (iii) develop appropriate monitoring and screening behaviours, (iv) encourage acceptance of the uncertainty brought about by a cancer diagnosis, and (v) clarify values and encourage engagement in values-based goal setting.

First stage intervention: eHealthMaintenance

Participants in the eHealthMaintenance group will receive six videos, which were designed to provide comprehensive lifestyle guidance (e.g., relaxation techniques, diet and physical activity advices) to help with survivors' maintenance of health in long-term.

Group Type ACTIVE_COMPARATOR

eHealthMaintenance

Intervention Type BEHAVIORAL

eHealthMaintenance is not developed specifically to target fear of cancer recurrence through modifying participants' cognitive beliefs. Participants in this arm will receive 6 videos about relaxation, generic dietary and exercise knowledge.

Second stage intervention: ConquerFear-HK

ConquerFear-HK is a culturally adapted, manualized intervention consisting of 6 individual face-to-face sessions over 10 weeks.

Group Type EXPERIMENTAL

ConquerFear

Intervention Type BEHAVIORAL

ConquerFear is an intensive version of eConquerFear, which consists of 6 face-to-face therapist-led sessions.

Second stage intervention: eConquerFear+eHealthMaintenance

The augmented eConquerFear + eHealthMaintenance intervention is a combined unsupervised, self-guided web-based intervention that consists of 10 weekly online modules covering the content of eConquerFear and eHealthMaintenance interventions.

Group Type ACTIVE_COMPARATOR

eConquerFear+eHealthMaintenance

Intervention Type BEHAVIORAL

The combination of eConquerFear and eHealthMaintenance interventions, that consists of 10 weekly online modules.
