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.
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.

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

Change of fear of cancer recurrence (FCR)
The primary outcome is the change in the total score of FCR assessed using the 42-item Fear of Cancer Recurrence Inventory (FCRI). The FCRI measures seven dimensions of FCR: (1) triggers, (2) severity, (3) psychological distress, (4) functional impairment, (5) reassurance, (6) insights, and (7) coping strategies. All items are rated on 5-point Likert scales ranging from 0 (not at all or never) to 4 (a great deal or all the time). Higher scores indicate higher levels of FCR.
Time frame: baseline (T0), one-month post-intervention (T1), and six-month (T2) post intervention
Change of metacognitions
Metacognition assessed by the 30-item Metacognitions Questionnaire (MCQ). The MCQ assesses individual differences in metacognitive beliefs, judgements, and monitoring tendencies across five domains: (1) positive beliefs about worry, (2) negative beliefs about thoughts concerning uncontrollability and danger, (3) cognitive confidence, (4) cognitive self-consciousness, and (5) the need to control thoughts. All items are rated on a 4-point Likert scale ranging from 1 (do not agree) to 4 (agree very much). Higher scores indicate higher levels of maladaptive metacognition.
Time frame: baseline (T0), one-month post-intervention (T1), and six-month (T2) post intervention
Change of cognitive attentional syndrome
CAS measured by the 16-item Cognitive Attentional Syndrome-1 (CAS-1) questionnaire.The CAS-1 assesses the frequency of engaging in rumination, threat monitoring, and coping behaviors, as well as the level of metacognitive beliefs. Each item is rated on a 9-point Likert scale ranging from 0 to 8, except for items measuring metacognitive beliefs, which are rated on a scale from 0 to 100. Higher scores indicate higher levels of CAS activation.
Time frame: baseline (T0), one-month post-intervention (T1), and six-month (T2) post intervention
