Brief Summary
In populations with substance use disorders (SUD), there is a high prevalence of chronic pain with various underlying causes. Chronic pain can complicate the treatment of SUD and lead to poorer treatment outcomes. There is a need for a better understanding of the connections and interactions between chronic pain and substance use and dependence. Further, there is a high prevalence of chronic pain among patients with post-traumatic stress disorder (PTSD). As there is an overlap between populations with SUD and PTSD, taking potentially traumatizing life-experiences and post-traumatic stress symptoms into account can provide a better understanding of chronic pain in populations with SUD. The Nor-APT study is a cross-sectional study, recruiting from outpatient and inpatient substance use treatment centres connected to four hospitals. Participants complete a questionnaire about substance/medication use, pain and how pain affect function, stressful life events and post-traumatic stress symptoms. Patients can consent to self-reported data being linked to retrospective and prospective longitudinal data from national demographic and health registries. The purpose of the study is to contribute to a better understanding and treatment of chronic pain among people with substance use disorders (SUD), and to contribute to the understanding of co-occurring substance use, chronic pain and post-traumatic stress symptoms. The over-arching research aims are to: I. Describe the prevalence and characteristics of pain for people in need of treatment for substance/medication use/dependence. II. Describe how the pain affects physical and emotional functioning, and subjective quality of life. III. Explore any connections between substance/medication use and pain, both what came first and any ways substance/medication use and pain affect each other. IV. Explore the connection between chronic pain, potentially traumatizing life events and post-traumatic stress symptoms. V. Explore how treatments received and how treatment affects outcomes. In addition, we will explore whether participants' experiences can be categorized into typical trajectories for how substance use, chronic pain and stressful life events occur and develop over the life span.

Outcome Measures
Primary Outcomes (4)
Chronic pain (ICD-10)
Defined as having experienced pain with a duration of at least 3 months.
T1 (at enrollment in study)
European-Addiction Severity Index (EuropASI), Section E
* Types of substances used (life-time), age of first use, and frequency of use in the last 4 weeks. * Intravenous use (life-time and last 4 weeks) Modifications: 1. We updated the list of substances to better match the relevant substances in use today: Alcohol to intoxication; OMT medications (methadone; subutex; suboxone); Other opioid painkillers (e.g. morphine, oxycodone, tramadol); Cannabis; Amphetamine/ Methamphetamine; Cocaine; Benzodiazepines; GHB; Hallucinogenics (e.g. LSD, mushrooms, mescaline); Anabolic steroids; Khat. 2. Frequency of use in the last 4 weeks: the response categories "used not more than 2-3 times per month" and " used 1-3 times a week" were collapsed into one category "used a few times", leaving three categories: "Not used", "used a few times" and "every day/nearly every day".
T1 (at enrollment in study)
The Stressful Life-Events Screening Questionnaire (SLESQ)
The SLESQ assesses exposure to stressful life-events (yes/no) that could be potentially traumatizing. This version has been shortened and adapted in previous studies at the Norwegian Centre for Violence and Traumatic Stress Studies (NKVTS) for use in Norway and includes a list of 15 types of stressful events. This variable will be used to assess the prevalence of different types of stressful life-events. In addition the number of events can be summed to indicate the extent of exposure to stressful life-event, with a range from 0 events to 15. Modifications: 1. Two events have been added: Being directly involved in a natural disaster and having been repeatedly ridiculed, put down, ignored or told you were no good by someone outside the family. 2. When several of the 15 types of events have occured, the participants' age at the time of the event is only recorded for the first event and the event that gives the participant the most symptoms now.
T1 (at enrollment in study)
The PTSD Checklist for DSM-5 - short version (PCL-5 short)
The short version of the PTSD Checklist for DSM-5 includes 4 items: 1 item for each symptom cluster for the diagnosis of PTSD according to the DSM-5. Participants indicate how much each symptom has bothered them in the last month on a scale from 0 to 4 ("Not at all" to "Very much"). The sum score ranges from 0 to 16. A score above the cut score of 10 indicates risk for PTSD, and has previously been validated as a diagnostic indicator.

Eligibility Criteria
Patients (ages 18 years - unlimited) in treatment for substance use disorders at outpatient and inpatient treatment centers connected to Akerhus University Hospital or Oslo University Hospital, Norway.
You may qualify if:
- Patient in substance use treatment at a treatment centre under Akershus University Hospital, Oslo University Hospital, Vestfold Hospital or Telemark Hospital.
You may not qualify if:
- Staff considers the patient to be unable to give informed consent/valid responses on the questionnaire OR staff considers participation to be too stressful/burdensome to the patient. Staff are asked to take the following into consideration when making their assessment:
- Acute withdrawal
- Acute intoxication
- Serious mental health concerns
- Serious physical health concerns
