Distress in Adolescents With Chronic Pain: Who is at Risk, When, and Why

This study aims to address the following research questions:

• What are the factors (moderators) that determine why some adolescents with chronic pain may experience suicidal distress but not others, and through which mechanisms (mediators) does chronic pain increase such distress over time?

Primary objective:

The investigators will use the repeated survey data (at day 0, 15, and 31):

• To explore the extent to which pain interference (at baseline) is associated with suicidal distress (primarily hopelessness and entrapment, and secondarily suicidal and self-harm thoughts and behaviours), measured repeatedly over time.

Secondary objectives:

The investigators will use the experience sampling data (5x day/30 days: day 1-30) to explore:

• how the relationship between pain interference and suicidal distress unfolds in the patient's daily life.
• the moderators (collected at baseline, survey data) that determine why some young people with chronic pain may experience suicidal distress over time, but not others.
• the mechanisms (experience sampling items) underpinning the potential relationship between pain interference and suicidal distress in the patient's daily life.

Inclusion criteria

• Participant is willing and able to give assent (aged 12-15 years) or informed consent (aged 16 years and older) for participation in the study,
• Parent/guardian is willing to give informed consent for participants aged 12-15 years.
• Adolescents aged 12 to 19 years.
• Were accepted for assessment at a tertiary specialist paediatric pain service, indicating by definition that they experience long-standing, treatment-resistant chronic pain that is functionally interfering.
• Able to read and converse fluently in English.
• Participant is willing to install the m-Path app on a smartphone that runs on Android or iOS to complete the daily assessments. (Please note that a recent Ofcom report has shown that by the age of 12 years, 98% of young people in the UK have their own mobile phone, used by 93% to access social media apps or sites. This supports the nearly universal access of smartphones in this age group)

Exclusion criteria

• If some serious acute pathology (e.g., infection, fracture, disease process (e.g., cancer with a potentially fatal trajectory)) or surgical procedure is the cause of the resulting pain complaint.
• If the patient is too psychologically unstable to safely participate in this research, based on clinical judgment (e.g., experiences of acute psychosis)
