Observational Study
Presurgical sleep and pain behaviors predict insomnia symptoms and pain after total knee arthroplasty: A 12-Month Longitudinal, Observational Study.
Up to 40% of individuals who undergo total knee arthroplasty (TKA) experience some degree of pain following surgery. Presurgical insomnia has been identified as a predictor of postsurgical pain; however, modifiable presurgical behaviors related to insomnia have received minimal attention. The objective of the present study was to develop a 2-item sleep and pain behavior scale (SP2) to investigate a maladaptive sleep and pain behavior and is a secondary analysis of a larger, parent study. ⋯ This provides preliminary evidence that patients who cope with pain by retiring to their bed and bedroom have higher rates of post-surgical insomnia and pain and supports efforts to target this maladaptive sleep and pain behavior to reduce postsurgical pain.

Observational Study
The Mediating Effect of Social Functioning on the Relationship between Catastrophizing and Pain among Patients with Chronic Low Back Pain.
Pain catastrophizing can be characterized as an interpersonal form of coping used to elicit support or empathy from others. Despite intentions of increasing support, catastrophizing can impair social functioning. While considerable work has addressed the relationship between catastrophizing and pain, limited empirical work has examined this relationship within a social context. First, we examined the role of catastrophizing as a potential contributor to group differences (chronic low back pain [cLBP] vs pain-free controls) in social functioning. Then we conducted a follow-up, exploratory analysis to examine the relationships between catastrophizing, social functioning, and pain within the subgroup of participants with cLBP. ⋯ We showed that impaired social functioning was driving the relationship between higher pain catastrophizing and worse pain among participants with cLBP. Interventions, such as cognitive behavioral therapy, should address catastrophizing in individuals with cLBP, while simultaneously improving social functioning.
