Outcome Measures

Primary Outcomes (2)

  • Chronic post-surgical pain

    Measured through a Numeric Rating Scale (NRS) for pain intensity. The scale ranges from 0-10, anchored by verbal descriptors at either end of the scale where 0 is no pain at all and 10 is the worst possible pain.

    3 months after surgery

  • Post-surgical fatigue

    Measured through the 13-item Functional Assessment of Chronic Illness Therapy-Fatigue subscale (FACIT-F) which is a unidimensional self-report scale to assess fatigue and its impact on daily life. The score range is 0-52 where a higher score indicates better quality of life (i.e. less symptoms and disability)

    3 months after surgery

Secondary Outcomes (6)

  • Pain intensity, pain unpleasantness, fatigue, nausea, physical discomfort and emotional upset

    On the day of surgery right before discharge

  • Stress (immunological) reactivity

    Baseline (pre-surgery) plus 4 weeks post-surgery (Cortisol will only be measured at baseline)

  • Number of psychotropic and pain-related prescriptions

    3 and 12 months post-surgery

  • Number of sick leave days

    3 and 12 months post-surgery

  • Psychological flexibility

    3 and 12 months post-surgery

  • +1 more secondary outcomes
