Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: Participants will receive a tailored programme of text messages (SMS) via their mobile phone. The messages will provide instructional, informational, and emotional support. These will include evidence-based information on the nature and symptoms of depression, understanding treatment options, strategies to improve parent-child communication, parent self-care, and useful links to resources. Input and feedback on the content of the text messages have been obtained from parents and caregivers as part of the development phase via focus groups, and have been fine-tuned to meet the needs of parents of teenagers.

The intervention will be delivered over 4 weeks, with participants receiving one text per day. Participants are able to choose the time period of which they wish to receive the text. Text messages will be one way, however participants are able to discontinue receving the text messages should they wish to by replying "STOP".. Participants will receive all the text-messages free of charge.

Comparator / control treatment
Care as usual: Participants allocated to the care-as-usual control group will receive no intervention from the research team, and can access alternative services if they so desire. On completion of the 3-months follow up assessment, participants will be offered the SMS mobile-based intervention programme.

Eligibility
Key inclusion criteria

Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants can either call or text a phone number to speak with a research assistant or leave their contact details via email. The research assistant will contact the participant and explain the study and ask screening questions to ascertain their eligibility to participant.

Eligible participants who indicate interest will receive an email with study registration details. By clicking on a link in the email they will be able to fill in their registration details and provide e-consent (participants consenting using computer based consent form).

Participants will then be directed to complete the baseline assessment.

Randomisation will be performed upon completion of the baseline assessment, and participants will be notified via email which group they have been allocated to. Those that are randomised into the intervention group will receive the intervention programme the day following the notification email. Participants that are randomised into the care-as-usual group will receive no intervention from the research group.

Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be generated by the trial statistician using block randomisation with variable block sizes of 2 or 4, and stratified by Maori, Pacific and non-Maori/non-Pacific. The randomisation lists will be concealed in database until the point of randomisation.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
The intervention group receives the intervention straight after completing baseline assessment.
The control group receives no intervention during the trial. The control group receives the intervention after all three sets of questionnaires at the three different time points have been completed.

Efficacy
Statistical methods / analysis
Two-hundred and fourteen participants will be recruited in total (one parent per household). This sample size (107 in each arm), will provide 80% power at p=0.05 to detect an effect size of a 2.5 difference in the Parenting Sense of Competence scale (PSOC) score at 1 month follow up (SD=5.8). This sample size estimate includes an estimated 20% loss to follow up in both trial arms.

Data from the RCT will be entered into a RedCap database, and following cleaning and datalock, extracted into SAS (version 9.4) for analysis. All data analyses will be specified a priori in a statistical analysis plan. No interim analysis will be undertaken. Baseline characteristics: Baseline data collected from all participants will be summarised by treatment group, overall and by ethnicity (Maori and Pasifika). Continuous variables will be presented as numbers observed, means and standard deviations. Categorical variables will be presented as frequencies and percentages. Since any differences between randomised groups at baseline could only have occurred by chance, no formal significance testing will be conducted. Intervention effects: Analysis will be carried out on an intention-to-treat basis. Sensitivity analyses will be undertaken to determine the impact of missing data. Regression models appropriate to continuous and categorical outcome variables will be used to assess the overall intervention effect, adjusting for baseline outcome value and other covariates, if needed. Repeated measures analyses will be conducted on outcomes measured repeatedly over time.
