Interventional
Description of intervention(s) / exposure
The design is a randomised controlled trial with two arms. The intervention arm is a novel cognitive behavioural intervention designed for this study; it aims to strengthen the adolescent’s supportive relationships (Teen Connect Triple P; TCTP). We will be using an active control condition; the Blues Program is an existing cognitive behavioural program typical of those used in Australian mental health clinics for adolescents with symptoms of depression and anxiety. Both arms will be delivered by therapists enrolled in advanced post-graduate clinical psychology training under the supervision of endorsed Clinical Psychologists. The interventions will be delivered online via Zoom. Participants will be in their own homes and therapists will be located at either The University of Queensland or QIMR Berghofer.

Interventions consist of six weekly therapist-led group sessions of 1.5 hours each. Each adolescent will participate in a group with 5 other adolescents. Altogether, there will be 8 groups of TCTP and 8 groups of the Blues Program. In TCTP, parents will also participate (also in groups of 6) in parallel sessions to their teenagers. Adolescents and their parents participate in separate streams focusing on reciprocal social and emotional skills. Adolescents learn how to strengthen friendships, interpret motives of peers, address issues calmly and assertively, resolve conflicts and seek help from their parents when needed. Parents learn how to support their adolescent’s friendships, listen to their adolescent’s concerns (without over-reacting or taking over), help their adolescent interpret peer motives, coach their adolescent in managing problems, and support their adolescents in making decisions and becoming independent. In each session, therapists educate participants about effective strategies through directed group discussions, skills-building exercises (modelling and role plays) and goal-setting for personal use.

Both TCTP and The Blues Program are manualised meaning that there are set workbooks for adolescents (and parents for TCTP), prescribed activities for therapists to facilitate and set information for therapists to deliver and pre-set homework tasks for therapists to set for each session.

Regarding fidelity, research assistants will attend 33% of groups to evaluate this through protocol checklists.

The parent and teenager workbooks for the Teen Connect Triple P program have been developed for this study.

Behaviour
Comparator / control treatment
The Blues Program will be used for the active control arm. The Blues Program is an existing cognitive behavioural program, which is typical of the psych-educational intervention that adolescents with internalising problems would receive in an outpatient mental health clinic in Australia. The Blues Program will be delivered over the same period as TCTP, i.e. 6 x 1.5 hour weekly sessions. These will also be delivered via Zoom to groups of 6 adolescents.

(1) An adolescent/child enrolled in an Australian school in Years 7-12 (ages 11-19 years)
(2) In the initial screening interview, the parent’s score is in the elevated (borderline) range for both the Peer Problems (i.e. a score of 3/10 or higher) and the Emotional problems subscale (i.e. a score of 4/10 or higher) of the Strengths and Difficulties Questionnaire (a standard screening instrument)
(3) The parent reports they have access to the minimal technology (a phone or computer with a camera and microphone and reliable internet access), that will allow participation in online sessions through Zoom.
Minimum age
11 Years
Maximum age
No limit
Sex

Can healthy volunteers participate?
Yes
Key exclusion criteria
Exclusion criteria include:
(1) Adolescents who attend special schools (and are therefore likely to have developmental delays affecting language),
(2) Families that report other barriers to parental and adolescent participation in an online program such as insufficient English language, a severe visual or hearing impairment that will impede full participation in sessions, and
(3) Either an answer of “yes” to both questions about adolescent suicidality either in the initial parent interview or the initial online adolescent questionnaire OR a determination that the adolescent is actively suicidal (currently considered or intended plan of action) during their follow-up phone-call if the adolescent answered “yes” to one of the suicidality screeners in the online questionnaire.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Statisticians will request a random binary number sequence from a colleague not associated with the project. Participants will only be randomised to a treatment after they have been deemed eligible to take part in the study. The psychologists completing the screening and eligibility criteria testing will not be involved in the randomisation procedure. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The sequence will include 104 numbers that are either “1’s” (designating the TCTP condition) or “2’s” (designating the Blues program condition). We will request block randomisation for each group of 20 numbers to ensure a roughly equal allocation to each condition throughout recruitment. As program will be conducted with groups of six families, block randomisation will help ensure that families do not have to wait too long for a suitable group to start.

Efficacy
Statistical methods / analysis
For this pilot RCT, a sample size of at least 70 families is required for reliable estimation of parameters for a full RCT. Allowing for possible attrition of up to 20%, we aim to recruit at least 84 families. Data will be analysed on an intention-to-treat basis with missing data handled through multiple imputations. We will use linear mixed-effects models for repeated measures (with measurements nested within individuals) to compare change in time over the two treatment arms; this will inform calculation of the sample size required for the full RCT. Any deviation(s) from this original statistical plan will be described and justified in the final report.
