NAME
Tuning Into Teens (TINT)
WHY
TINT is an evidence-based adaptation of the Tuning into Kids (TIK) parenting program for adolescents aged 10-18, based on an emotion socialisation theoretical framework. The goal of the TINT program is to teach parents an adaptive style of responding to children’s emotions, called ‘emotion coaching’.
WHAT
The TINT program uses a variety of methods, including a) lecturing and audio visual material to deliver new content, b) specific exercises that allow practicing a newly learned skill and c) several methods of role play. The topic of the sessions include: 1) Foundations for emotion coaching 2) Connecting and emotional acceptance 3) Building intimacy and showing empathy 4) Emotion coaching worry and sadness 4) Emotion coaching anger 6) Emotion coaching now and in the future. All program materials are readily available resources from the TIK suite, as provided by the author of the program.
WHO PROVIDED
Facilitators will be research fellows and graduate research students with a background in mental health trained in the TINT program. Debriefing and supervision will be provided weekly by the author of the program.
HOW
TINT involves an 8-week x 1 hourly one-on-one sessions. We will record the attendance of each participant. Only adolescents whose mothers complete at least 5 out of 8 TINT sessions will be eligible to complete all follow-up components (including the MRI).
WHERE
The intervention will be offered either online (via Zoom) or in person (Melbourne Neuropsychiatry Centre, The University of Melbourne).
TAILORING
The intervention is structured and will be delivered in the same way to all parents.

Efficacy
Statistical methods / analysis
A comprehensive set of group random-effects analyses adopting appropriate whole-brain criteria for statistical thresholding (familywise-error [FWE] corrected at the cluster level p < 0.05) will be performed to examine within group and between-group effects in relation to the primary task functional parameters of interest. For task-induced changes in BOLD signal activation, a general linear model will be set up for each participant and modelled according to the task-specific regressors. Statistical maps will be generated for each participant and contrasts will be set-up to look at conditions of interest within the task. ANCOVA will be used to examine group (intervention vs control) by time (baseline and 6 month follow-up) effects on whole- brain activation for the task. We will also use generalised psychophysiological interaction (gPPI) analysis to estimate whole brain connectivity with regions of interest (amygdala, ventromedial prefrontal cortex).

Brain function from significant clusters from the above analysis will be extracted and used in subsequent mediation models, which will test whether measures of parent emotion socialisation and other aspects of parenting (from the observed mother-daughter interaction task and questionnaires at post-intervention (follow-up 1) and 6 month follow-up) mediate the association between group (intervention vs control) and brain function at follow-up. Baseline BOLD signal activation and baseline parenting variables will be included as covariates in mediation analyses.

Adolescent baseline internalising symptoms (RCADS depression and anxiety symptom scores) will be tested as moderators in the above analyses to investigate whether adolescents with higher baseline symptoms are more likely to exhibit changes in brain function as a result of the intervention.

Exploratory: ANCOVA will be used to test group by time effects on hair cortisol concentration, and mediation analyses will be used to test whether brain function mediates the association between group and adolescent internalising symptoms and emotion regulation. baseline variables will be includes as covariates.

Summary
Brief summary
This project aims to understand how a parenting intervention influences emotional brain function in adolescent females at risk for depressive disorders.

Participants will be randomly assigned to the intervention or the waitlist control group. Parents of adolescents in the intervention group will receive the TINT parenting program, which has shown to be effective in increasing parental emotional socialisation and decreasing adolescents' internalising symptoms.

We hypothesise that adolescents whose parents are in the intervention group will show greater improvements in brain function and connectivity in the neural circuits underlying emotion regulation (i.e., greater reductions in amygdala activity and greater increases in prefrontal-amygdala connectivity) at 6-month follow-up compared to adolescents whose parents are in the waitlist control group.
