Brief Summary

Background: The loss of loved one to cancer brings unique difficulties that impact on the bereavement experience. Mixed support exists for the effectiveness of in-person group interventions for bereaved caregivers, with barriers to accessing support including perceived stigmatisation and geographical constraints. Online bereavement interventions offer an accessible and effective means of providing grief support to various populations at the individual and group level. Research supports the effectiveness of online groups for those bereaved by cancer, although most of these studies are peer-led as opposed to therapist-led. Despite a growing rationale for the use of online groups for bereavement, there is little empirical evidence for therapist led groups, or for those bereaved by cancer. Objectives: This paper describes the protocol for a pilot feasibility trial evaluating the feasibility, potential effectiveness and acceptability of delivering online therapy groups for those bereaved by cancer. Methods and analysis: It will use a longitudinal pilot and feasibility methodology to evaluate a randomised controlled trial (RCT) design and its suitability for a future definitive RCT. Participants: A total of 100 adults who have lost a loved one to cancer will be randomised to receive the intervention immediately or after a delay three months later. Interventions: An eight-session online therapeutic group intervention led over 12 weeks based on models of cognitive behavioural therapy, compassion focused therapy and coping with bereavement. Primary outcome measures: Cancer- bereaved adults' grief intensity, depression, anxiety, PTSD, self-compassion and social disconnection. Acceptability of the intervention will also be measured including what participants found most helpful or unhelpful about the groups and any adverse outcomes. Data collection will occur at baseline, intervention completion and at follow up, 3 months after intervention completion. Results: The feasibility of trial procedures and the effect of the intervention on the outcomes will be tested,. Conclusions: At intervention completion, it is hoped that participants will show reductions across all outcomes measures with improvements remaining at follow up, compared to the waitlist-control group, warranting the need for a full-scale RCT to establish efficacy.

Detailed Description

The loss of a loved one to cancer brings unique difficulties that impact the bereavement experience. Mixed evidence exists for the effectiveness of in-person group interventions for bereaved caregivers, with barriers to access including perceived stigmatisation and geographical constraints. Online bereavement interventions offer an accessible, destigmatising and effective means of providing grief support to various populations at the individual and group level. Research supports the effectiveness for online groups for those bereaved by cancer, although most of these studies are peer-led as opposed to therapist-led. Despite a growing rationale for the use of online groups for bereavement, there is little (if any) empirical evidence for therapist led groups, or for those bereaved by cancer.

A group bereavement therapy programme was developed by the Loss Foundation, a national cancer bereavement charity, who initiated the project. It will explore the impact of an eight-session therapeutic group intervention led over 12 weeks on cancer- bereaved adults' grief intensity, depression, anxiety, PTSD, self-compassion and social disconnection. Previous research within the Loss Foundation has demonstrated the effectiveness of an in-person cancer bereavement therapeutic group using a transdiagnostic model (Jerome et al., 2018). In this study, it was found that grief intensity and symptoms of posttraumatic stress disorder (PTSD), depression, and anxiety were reduced postintervention, and self-compassion increased. At follow-up, improvement remained for grief, PTSD, and depression. This intervention has been adapted and carried out several times from previous research, including methodological changes such as randomisation to a waitlist control and collection of weekly data. For example, previous research within The Loss Foundation explored the effectiveness of the in-person cancer bereavement therapeutic group compared to waitlist control with findings showing a reduction in grief intensity and increased self-compassion.

As this is the first online therapeutic bereavement group for those bereaved by cancer, this study offers a unique contribution to the literature, addressing a critical gap in the literature on evidence-based therapist led internet interventions for cancer bereaved adults. The intention is to ascertain the feasibility, acceptability and changes in self-report measures of the online version of the adapted group bereavement therapy programme for cancer. This feasibility pilot study will evaluate a randomised controlled trial (RCT) design to explore its suitability for a further full-scale RCT. Outcomes will be assessed by comparing intervention and wait-list control groups at baseline, post each session and postintervention 3 months later in terms of the following primary outcomes: grief intensity, depression, anxiety, PTSD, self-compassion and social disconnection.

Aims and objectives

1. The primary aim is to evaluate the feasibility and acceptability of delivering online bereavement group for cancer loss. This refers to feasibility to recruit, retain, randomise and acceptability as tracking participant satisfaction and any adverse outcomes.

2. The secondary aim is to explore the preliminary effectiveness by examining whether the online bereavement group intervention leads to improvements on various outcomes, compared to the waitlist control.

The investigators' hypotheses are informed by the results of previous research within The Loss Foundation, and previous literature suggesting that online groups may be similarly effective. In regard to the secondary aim of exploring preliminary effectiveness of the study, the investigators hypothesised that grief intensity and PTSD symptoms, depression, and anxiety will be reduced postintervention, and self-compassion will be increased, showing improvement from baseline, compared to the waitlist control. Further, the investigators hypothesise that at follow-up, improvement will be maintained for grief intensity, PTSD symptoms and depression.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Immediate Treatment

Participants randomised to non-waitlist, accessing the online bereavement group intervention immediately

Group Type: EXPERIMENTAL

Therapeutic - Psychological

Intervention Type: BEHAVIORAL

The intervention uses a transdiagnostic model that incorporates aspects of peer support, psychoeducation, trauma-informed cognitive behavioural therapy (CBT), Compassion focused therapy (CFT) models of distress. It also aligns itself to the Dual Processing Model of coping with bereavement (Stroebe \& Schut, 2010) and Tonkin's model of grief (Tonkin, 1996).

Waitlist-Control Group

participants randomised to waitlist-control accessing the online bereavement group intervention after a delay (three months later) immediate group

Group Type: OTHER

Therapeutic - Psychological

Intervention Type: BEHAVIORAL

The intervention uses a transdiagnostic model that incorporates aspects of peer support, psychoeducation, trauma-informed cognitive behavioural therapy (CBT), Compassion focused therapy (CFT) models of distress. It also aligns itself to the Dual Processing Model of coping with bereavement (Stroebe \& Schut, 2010) and Tonkin's model of grief (Tonkin, 1996).

Eligibility Criteria

Inclusion Criteria

• (3) Self-referral to The Loss Foundation or via a related organisation
• (4) Have the means to access the therapeutic group online
• (5) Participants consent to attending the intervention with the risk of a delay (e.g. by being randomised to the waitlist or non-waitlist group).

Exclusion Criteria

1. Adults at high risk to themselves or others in regard to suicide and/or self-harm

2. Significant substance or alcohol misuse which would interfere with participants' ability to take part in the research

3. Cannot be involved in other therapy at the same time elsewhere.
