About this study
Suicide is a major public health concern and there is a need for accessible and scalable interventions to support individuals experiencing suicidal thoughts. The aim of this study is to develop a digital Acceptance and Commitment Therapy (ACT) intervention for suicide prevention in Chinese adults through co-design. The study will involve literature review, interviews, and co-design activities to identify user needs, preferences, and contextual factors, and to develop the intervention. Following intervention development, a pilot study will be conducted to evaluate the feasibility, usability, acceptability, and user engagement of the intervention. Findings from this study will inform further refinement of the intervention and future evaluation studies.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Digital ACT InterventionBehavioural
A co-designed digital Acceptance and Commitment Therapy (ACT) intervention for suicide prevention
| Study group | Role | What they receive |
|---|---|---|
| Digital ACT Intervention | Experimental | The Digital ACT Intervention will be co-designed with stakeholders and informed by co-design activities. The intervention aims to support adults experiencing suicidal thoughts through a digital platform. Receives: Behavioral: Digital ACT Intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Intervention completion rate
The intervention completion rate will be assessed as the percentage of participants who complete the digital intervention, based on intervention usage records.
Measured: End of the intervention (approximately 2 weeks)
Retention rate
The participant retention rate will be assessed as the percentage of participants who complete the post-intervention assessment and the follow-up assessment.
Measured: End of the 1-month follow-up
Acceptability outcome
Acceptability of the intervention will be assessed using participant-reported ratings and feedback regarding satisfaction and overall experience with the intervention.
Measured: End of the intervention (approximately 2 weeks)
Usability outcome
Usability will be assessed using the System Usability Scale (SUS), a 10-item self-report questionnaire. Total scores range from 0 to 100, with higher scores indicating better usability of the intervention.
Measured: End of the intervention (approximately 2 weeks)
Secondary outcomes (4)
Suicide ideation
Suicidal ideation will be assessed using the Beck Scale for Suicide Ideation (BSSI). Each item is rated on a 3-point scale ranging from 0 to 2, with higher scores indicating greater suicidal ideation.
Measured: Baseline, end of the 2-week intervention, and 1-month follow-up
Psychological flexibility and inflexibility
Psychological flexibility and inflexibility will be assessed using the Multidimensional Psychological Flexibility Inventory-24 (MPFI-24). Each item is rated on a 6-point scale ranging from 1 to 6. Higher scores on the flexibility and inflexibility subscales indicate greater psychological flexibility and psychological inflexibility, respectively.
Measured: Baseline, end of the 2-week intervention, and 1-month follow-up
Psychological Distress
Psychological distress will be assessed using the Depression Anxiety Stress Scales (DASS). Each item is rated on a 4-point scale ranging from 0 to 3, with higher scores indicating greater psychological distress.
Measured: Baseline, end of the 2-week intervention, and 1-month follow-up
Mental well-being
Mental well-being will be assessed using the Mental Health Continuum-Short Form (MHC-SF). Each item is rated on a 6-point scale ranging from 0 to 5, with higher scores indicating greater mental well-being.
Measured: Baseline, end of the 2-week intervention, and 1-month follow-up
