- AbstractObjectives: This study aimed to investigate the acceptability of study participation and feasibility of i) recruitment, ii) data collection and iii) outcome measures of a prospective cohort of patients with chronic-non-cancer pain (CNCP), the U-PAIN cohort. The overall aim of the cohort study is to identify predictors for risks and benefits associated with chronic opioid therapy (COT). Design: Internal feasibility study including baseline data and retention rate of the one-year follow-up. Setting: A secondary and tertiary care Pain Center at a university hospital in Sweden with a national catchment area.Participants: Sixty-four patients with CNCP, > 18 years, literate in Swedish, referred to consultation and/or treatment at the Pain Centre. Outcome measures: Acceptability of study participation was measured with a study-specific 10-item Likert scale. Feasibility of recruitment was assessed by recording participation rates at baseline and number of individuals completing the one-year follow-up. Feasibility of data collection and outcome measures in the cohort study were examined by completions rates of study procedures, sample scores, and agreement between self-reported data and data retrieved from medical records on opioid use. Results: Study participants reported an overall acceptable satisfaction with Participation retention rate at the one-year follow-up was 82%. The completion rates for the different data collection methods ranged from 83% to 95%. Agreement between self-reported opioid use and prescribed dose was high (к= .91). Eleven individuals met the criteria for any OUD, and three individuals met the criteria for moderate- severe OUD. Agreement between OUD according to DSM-5, and clinical ICD-10 diagnoses for opioid dependence measured with prevalence-adjusted and bias-adjusted kappa (PABAK) was high (κ= .90). The participants reported poor work ability. Conclusions: This feasibility study has helped to highlight and improve methods for recruitment, data collection and use of outcome measures for the U-PAIN cohort. A majority of participants reported an overall satisfaction with study participation, and the methods used for data collection were found feasible. .Low participation rate, and high refusal rates at baseline is a challenge that needs to be further addressed.

- Objectives This study aimed to examine the psychometric properties of a Swedish version of the Medical Outcomes Study Social Support Survey (MOS-SSS).Methods Standard forward-backward translation was used. A cross-sectional survey was conducted among treatment seeking individuals with chronic pain included in a clinical cohort. Internal consistency was measured with Cronbach’s α, test-retest reliability was examined with intraclass correlation, confirmatory factor analyses was used for examining factor structure, and correlations between the MOS-SSS and selected health validity measures were used for testing concurrent validity hypotheses.Results 182 participants were included in the study. Internal consistency measured with Cronbach’s alpha was acceptable for all subscales and for the total support index of the MOS-SSS. Test-retest reliability was moderate – good for the different subscales, and was good for the overall support index. The original four factor model of the MOS-SSS was confirmed, and the concurrent validity hypotheses were also confirmed; however, the associations were weaker than expected.Conclusions The Swedish version of the MOS-SSS was found psychometrically sound and offers a systematic assessment of social support in specialized pain care.

- Objectives: The Addiction Severity Index (ASI) is a standardized interview used to assess problems associated with substance use. Although widely used, the time required for the interview remains an obstacle to its acceptance in many clinical settings. We examined if a self-administered questionnaire based on the composite score (CS) items, the ASI Self-Report form (ASI-SR), offers a reliable alternative to the ASI in assessing current substance use and related problems.Methods:Participants were 59 treatment seeking individuals entering outpatient programs at the Addiction Psychiatric Clinic at Uppsala University Hospital who were assessed with Swedish versions of the ASI and ASI-SR. Agreement between the ASI interview's CS and ASI-SR's CS was evaluated on the individual basis by intraclass correlation analysis (ICC) and on group level with the Wilcoxon signed rank test. Reliability and internal consistency were evaluated using Cronbach's alpha.Results:For 6 out of 7 CS domains, the ICC for the ASI interview and ASI-SR were good to excellent. Internal consistency was acceptable for 6 out of 7 CS domains on the ASI interview and for 5 out of 7 CS domains on the ASI-SR.Conclusions:The present study suggests that the ASI-SR is a reliable alternative to the ASI interview for assessing current patient functioning and evaluation of problems related to alcohol and drug use.

- Objectives To examine acceptability of study participation and feasibility of (1) recruitment, (2) data collection and (3) outcome measures for the prospective U-PAIN cohort. Design Internal feasibility study of a prospective cohort. Participants and setting 64 patients, >18 years, with chronic pain at a multidisciplinary pain centre at a university hospital in Sweden. Outcome measures Acceptability of study participation was measured with a study-specific 10-item Likert scale. A score <3 was considered feasible, for the two items that assessed respondent burden a higher score indicated lesser participant burden and a score >3 was feasible. Recruitment was assessed by participation rates at baseline and retention at the 1-year follow-up, with threshold values for feasibility at 75% and 80%, respectively. Data collection and outcome measures were examined by completions rates of study procedures (90% was considered feasible), sample scores, internal consistency (alpha>0.70 was considered feasible), and agreement between self-reported data and data retrieved from medical records on opioid use (ICC or kappa>0.60 was considered feasible). Results Acceptability for study procedures was feasible, but participation rates were low: 25%. The retention rate at 1-year follow-up was 81% for those included in the feasibility study, that is, filling out computerised patient-reported outcome measures, and 65% for those using paper and pencil format. The completion rates for the different data collection methods ranged from 83% to 95%. Agreement between self-reported opioid use and prescribed dose and between opioid use disorder according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and clinical International Classification of Diseases-10 (ICD-10) diagnoses for opioid dependence were almost perfect (kappa=0.91and kappa=0.90, respectively). Conclusions This feasibility study has helped to explore and improve methods for recruitment, data collection and use of outcome measures for the U-PAIN cohort. Low participation rate and high refusal rate at baseline is a challenge that needs to be further addressed.
