Brief Summary

Loneliness is a significant problem for young people and is associated with a range of physical and mental health difficulties. Meta-analyses have identified that interventions aimed at young people who report loneliness as their primary problem are lacking within the literature. In adults, the most effective interventions for loneliness are those which target the underlying maladaptive social cognitions. Therefore, the investigators have developed a modular Cognitive Behavioural Therapy (CBT) intervention for children and young people aiming to reduce their feelings of loneliness. The aim of this study is to conduct a multiple baseline single-case experimental design (SCED) to assess the efficacy, feasibility and acceptability of this intervention. In total 6-8 11-18-year-olds and their families will be recruited. The design consists of AB+ post-intervention, where A is the baseline phase, B is the intervention phase and then a post-intervention phase. Participants will complete a baseline assessment, before being randomised to one of four different baseline lengths (12 days, 19 days, 26 days or 33 days). Participants will then complete an average of 12 sessions of CBT, with the aim being to reduce their feelings of loneliness over 12 weeks. Participants will then complete a 12-day post-intervention phase. Participant loneliness will be repeatedly assessed throughout the three phases of the intervention using the Three-item Loneliness Scale, which will be the primary outcome. Secondary outcomes will be reliable and clinically meaningful change on the UCLA-LS-3, RCADS and SDQ. Feasibility and participant satisfaction will also be assessed and reported.

Outcome Measures

Primary Outcomes (1)

  • Change in scores on the Three Item Loneliness Scale (Klein et al., 2021) across the baseline, intervention and post-intervention phases.

    Self-reported child loneliness. The scale is a brief three-item measure with possible scores ranging from 0-12, with higher scores indicating higher levels of loneliness.

    This study is a single-case experimental design. Participants will complete the measure daily during the baseline phase, each session during the intervention phase, and daily during the post-intervention.

Secondary Outcomes (3)

  • UCLA-Loneliness Scale-3 (Russell, 1996)

    Completed at baseline and post-intervention assessments at study completion an average of 16 weeks later.

  • The Strengths and Difficulties Questionnaires (SDQ) (Goodman, 2001)

    Completed at baseline and post-intervention assessments at study completion an average of 16 weeks later.

  • The Revised Child Anxiety and Depression Scale (RCADS) (Chorpita et al., 2000)

    Completed at baseline and post-intervention assessments at study completion an average of 16 weeks later.

Other Outcomes (2)

  • Goal based outcomes (Law & Jacob, 2013)

    This will be completed each intervention session over an average of 12 weeks.

  • Visual analogue scales (VAS; see Wewers & Lowe, 1990 for review)

    This will be completed each intervention session over an average of 12 weeks.

Study Arms (5)

Cognitive Behavioural Therapy (CBT) for Chronic Loneliness

EXPERIMENTAL

Participants will receive an average of 12 50-minute sessions of CBT aiming to reduce their loneliness. The intervention is modular and has been developed for this study. In total there are 10 treatment modules, 1) Assessment, 2) Formulation and Psychoeducation, 3) Challenging Negative Interpersonal Appraisals and Counterproductive Behaviours, 4) Challenging Negative Thoughts and Cognitive Biases, 5) Challenging Self-focussed Attention, Hypervigilance and Camouflaging, 6) Values-based Social-skills Training, 7) Problem Solving, 8) Findings Friends, 9) Managing Emotions and 10) Relapse Prevention. All participants will complete module 1) Assessment and module 2) Formulation and Psychoeducation. They will then work with the clinician to collaboratively develop a treatment plan based on their formulation. The treatment will be comprised of one or more of the intervention modules. All participants will then complete module 10) Relapse Prevention at the end of their treatment.

Baseline Phase 1 (12 days)

NO INTERVENTION

The design of the study is a randomised multiple-baseline single-case experimental design (SCED). Participants will be randomised to one of 4 baseline lengths (12 days, 19 days, 26 days or 33 days). The baseline phase will act as the control condition within and between participants.

Baseline Phase 2 (19 days)

NO INTERVENTION

The design of the study is a randomised multiple-baseline single-case experimental design (SCED). Participants will be randomised to one of 4 baseline lengths (12 days, 19 days, 26 days or 33 days). The baseline phase will act as the control condition within and between participants.

Baseline Phase 3 (26 days)

NO INTERVENTION

The design of the study is a randomised multiple-baseline single-case experimental design (SCED). Participants will be randomised to one of 4 baseline lengths (12 days, 19 days, 26 days or 33 days). The baseline phase will act as the control condition within and between participants.

Baseline Phase 4 (33 days)

NO INTERVENTION

The design of the study is a randomised multiple-baseline single-case experimental design (SCED). Participants will be randomised to one of 4 baseline lengths (12 days, 19 days, 26 days or 33 days). The baseline phase will act as the control condition within and between participants.

Eligibility Criteria

Age11 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Be aged 11-18
  • Score more than 42 on the UCLA-LS-3 (Russel, 1996), which is more than one standard deviation above the mean in a large community adolescent sample (Shevlin, 2015).
  • Have a parent/carer who is willing to take part in the study.
  • Report loneliness as their primary difficulty (i.e., they are able to identify relevant goal-based outcomes and their current difficulties are not attributable to a significant mental health problem).

You may not qualify if:

  • Currently receiving psychological therapy.
  • Started taking antidepressant in the last 8 weeks.
  • Eligibility assessment indicates a severe mental health problem not considered suitable for the trial intervention due to the clinical need for immediate intervention, e.g., active suicidality and psychosis.
  • Refusal for therapy sessions to be video recorded.
  • Having an intellectual disability at a level whereby they cannot access the intervention
  • Do not have access to a laptop or smartphone which they can use for video calls.
