The behavioural inhibition system and activation system (BIS-BAS) model of pain focusses on two clusters of responses to pain-escape/avoidance (BIS) and approach (BAS) behaviours. While the BIS-BAS model emphasizes active responses to pain, deactivation responses such as despondence and relaxation are also common. This study sought to develop self-report scales assessing cognitive, behavioural intentions and affective responses to pain consistent with this extended BIS-BAS framework. We also sought to develop short-forms of the emerging scales. ⋯ The Pain Responses Scale emerging from this research assesses four theorized, overarching responses to pain: Escape, Approach, Giving Up and Relaxation. This measure will afford the capacity to test a reconceptualized BIS-BAS model of pain and inform treatments that are adapted based on this framework.

Spinal pain (SP), including neck and back pain, is common and often associated with poor mental health and reduced quality of life of adolescents. Contemporary understanding of SP favours a biopsychosocial approach, and emerging evidence suggests the stronger influence of psychological rather than other factors. ⋯ Our findings provide evidence that psychological distress early in life is an independent risk factor for spinal pain with impact during adolescence. As psychological distress during childhood is potentially modifiable, it may be a promising target for research on the prevention of consequential spinal pain in adolescence. Identifying and addressing psychological distress in children may be an important component of best practice to reduce consequential spinal pain in adolescents.

Recent studies with data-driven approaches have established common pain trajectories. It is uncertain whether these trajectory patterns are consistent over time, and if a shorter measurement period will provide accurate trajectories. ⋯ Having persistent pain and having very minor pain is relatively stable over one year, while episodic pain has more potential for shifts. The duration of measurement periods appears to have an impact on the results of the classification. The given criteria resulted in a reduced frequency of episodic pattern due to shorter measurement periods. Our findings contribute to improved understanding and predicting NP using a combination of patient characteristics and trajectory patterns.

Fibromyalgia (FM) is characterized by chronic widespread pain. Its pathophysiological mechanisms remain poorly understood, and effective diagnosis and treatments are lacking. This study aimed to identify significantly changed biosignatures in FM and propose a novel classification for FM based on pain and soreness (sng) symptoms. ⋯ In this study, we identified potential biomarkers from FM patients. The selected biomarkers could discriminate sng and pain phenotypes in FM patients. These results could help elucidate the underlying pathological mechanisms for more effective diagnosis and therapy for FM.

Observational Study
Five-year Observational Study of Internet-Delivered Cognitive Behavioural Pain Management when offered as Routine Care by an Online Therapy Clinic.
Internet-delivered cognitive behavioural pain management programmes (PMPs) are effective, but less is known about their use outside of research trials. Five years of data from offering the Internet-delivered cognitive behavioural PMP in an online therapy clinic was examined to assess effectiveness, acceptability and predictors of outcomes. ⋯ This 5-year observational study provides support for Internet-delivered cognitive behavioural pain management programs (PMPs) offered as routine care in an online therapy clinic. Interest in the service grew over 5 years. Outcomes, engagement and satisfaction were strong. Higher pain acceptance, pain self-efficacy and lower pain severity were associated with greater post-treatment improvements on depression, anxiety and disability.
