The present study examined the within-day relationship between fatigue and positive and negative mood among adults with rheumatoid arthritis (RA) or osteoarthritis (OA). ⋯ There was a unidirectional effect of fatigue on subsequent happiness and a bidirectional relationship between fatigue and frustration within the same-day for adults with RA or OA. These findings inform interventions for the management of mood and fatigue throughout the day and suggest that addressing fatigue could improve mood, and that addressing sources of frustration could improve fatigue among people with arthritis.

According to worldview verification theory, inconsistencies between lived experiences and worldviews are psychologically threatening. These inconsistencies may be key determinants of stress processes that influence cardiovascular health disparities. This preliminary examination considers how experiencing injustice can affect perceived racism and biological stress reactivity among African Americans. Guided by worldview verification theory, it was hypothesized that responses to receiving an unfair outcome would be moderated by fairness of the accompanying decision process, and that this effect would further depend on the consistency of the decision process with preexisting justice beliefs. ⋯ Biological and psychological processes that contribute to cardiovascular health disparities are affected by consistency between individual-level and contextual justice factors.

Research suggests that temporary abstinence from alcohol may convey physiological benefits and enhance well-being. The aim of this study was to address a lack of information about: (a) correlates of successful completion of a planned period of abstinence, and (b) how success or failure in planned abstinence affects subsequent alcohol consumption. ⋯ The findings suggest that participation in abstinence challenges such as Dry January may be associated with changes toward healthier drinking and greater DRSE, and is unlikely to result in undesirable "rebound effects": very few people reported increased alcohol consumption following a period of voluntary abstinence.

In the majority of patients a definitive cause for low back pain (LBP) cannot be established, and many patients report feeling uncertain about their diagnosis, accompanied by guilt. The relationship between diagnostic uncertainty, guilt, mood, and disability is currently unknown. This study tested 3 theoretical models to explore possible pathways between these factors. In Model 1, diagnostic uncertainty was hypothesized to correlate with pain-related guilt, which in turn would positively correlate with depression, anxiety and disability. Two alternative models were tested: (a) a path from depression and anxiety to guilt, from guilt to diagnostic uncertainty, and finally to disability; (b) a model in which depression and anxiety, and independently, diagnostic uncertainty, were associated with guilt, which in turn was associated with disability. ⋯ Two newly defined factors, pain related guilt and diagnostic uncertainty, appear to be linked to disability and mood in people with LBP. The causal path of these links cannot be established in this cross sectional study. However, pain-related guilt especially appears to be important, and future research should examine whether interventions directly targeting guilt improve outcomes.

Randomized Controlled Trial
The bidirectional relationship between sleep complaints and pain: Analysis of data from a randomized trial.
The goal of this study was to examine the bidirectional relationship of sleep and pain to determine whether changes in sleep complaints over the course of a chronic pain treatment trial predict pain outcomes and vice versa, controlling for changes in depression and anxiety. ⋯ This work helps to further disentangle the complex relationship between pain and sleep. This bidirectional relationship may need to be considered to improve pain outcomes.
