Exploring the Acceptability, Appropriateness, and Utility of a Digital Single-Session Intervention (Project SOLVE-NZ) for Adolescent Mental Health in New Zealand: Interview Study Among Students and Teachers.

TL;DR

Both Project SOLVE-NZ and Project Success-NZ were perceived as acceptable, appropriate, and useful for rangatahi in Aotearoa New Zealand, with participants endorsing their sociocultural relevance and potential to fill gaps in students' learning and mental health support.

Key Findings

Participants endorsed the sociocultural relevance of both Project SOLVE-NZ and Project Success-NZ to rangatahi in Aotearoa New Zealand and viewed all existing adaptations favorably.

  • 12 students aged 13-14 years (50% female) participated in a focus group
  • 8 teachers with a mean of 8.75 years (SD 7.96) teaching experience (62.5% female) participated in individual semistructured interviews
  • Data were analyzed using reflexive thematic analysis
  • Participants viewed all existing cultural and contextual adaptations favorably

Most participants had no preference between Project SOLVE-NZ and Project Success-NZ, viewing both as capable of providing ongoing support throughout the school year.

  • Both interventions were perceived as acceptable, appropriate, and useful
  • Participants believed both interventions could provide ongoing support to rangatahi throughout the school year
  • This finding has implications for the design of a future randomized controlled trial in which Project Success-NZ would serve as an active control condition

Participants believed the interventions would be valuable to a wide range of rangatahi and may be particularly relevant for youths experiencing economic hardship.

  • Participants felt the interventions would help fill gaps in students' learning
  • Participants perceived benefits to mental health from both interventions
  • Economic hardship was specifically identified as a context in which the interventions may be especially relevant

Teachers identified several strategies for increasing student engagement with the digital single-session interventions.

  • Suggestions included increased cultural and gender representation
  • Visual and literacy aids were recommended to accommodate a range of cognitive abilities
  • Whakawhanaungatanga (relationship building) was identified as an important element
  • Teacher guidance was suggested as a means of improving engagement

The study identified a significant treatment gap in adolescent mental health care in New Zealand that digital single-session interventions may help address.

  • Barriers to care identified globally include extensive wait times, high costs, and concerns about appropriateness for non-Western clients
  • Project SOLVE was originally developed in the United States and targets problem-solving skill deficits underlying broad-ranging psychopathology
  • The adapted version, Project SOLVE-NZ, was developed specifically for rangatahi in Aotearoa New Zealand
  • Digital SSIs were framed as a promising alternative to address the mental health treatment gap

The authors generated four recommendations for designing digital single-session interventions for young people based on interview findings.

  • Recommendation 1: involve rangatahi and relevant stakeholders in the design process
  • Recommendation 2: consider how the intervention will be implemented
  • Recommendation 3: ensure that the intervention accommodates a range of cognitive abilities
  • Recommendation 4: ensure that the intervention reflects the diversity of rangatahi today
