Benign or painful? The interpretation of pain and fear of progression in rheumatoid arthritis.

ABSTRACT: People with chronic pain tend to interpret ambiguous information as health-related, more so than people without. In this study, we aimed to investigate whether people with rheumatoid arthritis (RA) exhibit this interpretation bias and whether it is associated with fear of disease progression (FoP). The interpretation biases of people with RA (n = 164) were compared with an age- and gender-matched control group. We hypothesized that (1) people with RA would have larger interpretation biases than people without; (2) those who scored in the clinical range for FoP would have larger interpretation bias than those who did not; (3) interpretation bias would moderate the relationship between pain severity and FoP; and (4) interpretation bias would explain variance in FoP above and beyond other established predictors. Our results confirmed that people with RA were more likely to interpret ambiguous information as health-related compared with people without RA. This effect was more pronounced for the RA subgroup with clinically significant FoP than those scoring in the normal range. We did not find evidence to suggest interpretation bias moderated the relationship between pain and FoP or that FoP added to the variance of other known predictors. Our results indicate that interpretation bias is common amongst people with RA and is associated with FoP. Further research is required to illuminate the exact nature of this relationship.

A cross-sectional study of existential concerns and fear of progression in people with Rheumatoid Arthritis.

OBJECTIVES: People with rheumatoid arthritis (RA) have higher levels of fear of disease progression (FOP) than cancer survivors. In cancer, FOP is inextricably linked with existential concerns. However, this has not been investigated in people with RA. METHODS: We recruited 165 people with RA (96%F) who volunteered for a treatment trial of psychological intervention. Participants completed the Existential Concerns Questionnaire (ECQ) and questionnaires measuring constructs associated with FOP in cancer. We created groups of people with RA, with and without clinically significant levels of FOP (clinical and control groups) and compared their existential concerns. We hypothesized that existential concerns would add to the variance in FOP over and above pain, psychopathology, and disability. RESULTS: Nearly two-thirds of people with RA scored in the clinical range for FOP. The clinical group had higher levels of all existential concerns than the control group. When subscales of the ECQ were entered into a multiple regression with FOP as the dependent variable, death anxiety, meaninglessness and guilt domains accounted for significant variance in FOP. Moreover, when added to a regression equation controlling all other variables, existential concerns continued to account for unique variance in FOP (t = 2.712, p = 0.007). CONCLUSION: Existential concerns were strongly associated with FOP. While this cross-sectional study cannot determine whether existential concerns underlie FOP in RA, these results show robust relationships that warrant future investigation.

Randomised controlled trial of cognitive behaviour therapy versus mindfulness for people with rheumatoid arthritis with and without a history of recurrent depression: study protocol and design.

INTRODUCTION: Psychosocial treatments have been shown to benefit people with rheumatoid arthritis (RA) on various outcomes. Two evidence-based interventions are cognitive behavioural therapy (CBT) and mindfulness-based stress reduction (MBSR). However, these interventions have been compared only once. Results showed that CBT outperformed MBSR on some outcomes, but MBSR was more effective for people with RA with a history of recurrent depression, with efficacy being moderated by history of depressive episodes. However, this was a post-hoc finding based on a small subsample. We aim to examine whether a history of recurrent depression will moderate the relative efficacy of these treatments when delivered online. METHODS AND ANALYSIS: This study is a randomised controlled trial comparing CBT and MBSR delivered online with a waitlist control condition. History of recurrent depressive episodes will be assessed at baseline. The primary outcome will be pain interference. Secondary outcomes will include pain intensity, RA symptoms, depressive symptoms and anxiety symptoms. Outcome measures will be administered at baseline, post-treatment and at 6 months follow-up. We aim to recruit 300 participants, and an intention-to-treat analysis will be used. Linear mixed models will be used, with baseline levels of treatment outcomes as the covariate, and group and depressive status as fixed factors. The results will demonstrate whether online CBT and MBSR effectively improve outcomes among people with RA. Importantly, this trial will determine whether one intervention is more efficacious, and whether prior history of depression moderates this effect. ETHICS AND DISSEMINATION: The trial has been approved by the Human Research Ethics Committee of the University of Sydney (2021/516). The findings will be subject to publication irrespective of the final results of the study, and based on the outcomes presented in this protocol.

A randomized controlled trial of a web-based mindfulness programme for people with MS with and without a history of recurrent depression.

BACKGROUND: Evidence shows small positive effects associated with psychological treatments for people with multiple sclerosis (PwMS). In a recent meta-analysis, the treatment with the largest effect size was a mindfulness-based intervention (MBI). OBJECTIVES: We aimed to determine whether an Internet-delivered MBI was beneficial for PwMS. Furthermore, we aimed to investigate history of recurrent depression as a moderator of treatment outcome. METHODS: Participants (N = 132) were assessed based on whether they had a history of recurrent depression, then stratified and randomized to MBI or waitlist. Outcomes were assessed at baseline, post-intervention, and 3 and 6 months. RESULTS: The MBI group reported significantly improved depressive symptoms (primary outcome) compared with the waitlist (p = 0.046, Cohen's d = 0.39). Those with a history of recurrent depression benefitted significantly more than those without (p = 0.034, d = 0.66). There were benefits for health-related quality of life (HRQoL) in the MBI, irrespective of depression history (p = 0.009, d = 0.5). Pain interference was less overall in the MBI group (p < 0.001, d = 0.2), but change over time did not differ from waitlist. There were no treatment effects for anxiety, pain severity or fatigue. CONCLUSION: The Internet-delivered MBI significantly improved depressive symptoms and HRQoL in PwMS. For depression, the benefits were greater for those with a history of recurrent depression.

Development of a Web-Based Mindfulness Program for People With Multiple Sclerosis: Qualitative Co-Design Study.

BACKGROUND: Mindfulness-based stress reduction is an efficacious treatment for people with chronic health problems; however, it is highly intensive and time-consuming, which is a barrier for service provision. OBJECTIVE: This study aims to develop an internet-delivered adapted version of mindfulness-based stress reduction for people with multiple sclerosis to make the intervention more accessible. METHODS: We co-designed a web-based mindfulness program with end users, that is, people with multiple sclerosis (N=19). Iterative feedback was also collected from a subsample of the initial group of end users (n=11), and the program was reviewed by experts (n=8). RESULTS: We identified three main themes common to people with multiple sclerosis: dealing with uncertainty and fears for the future, grief and loss, and social isolation. These themes were incorporated into narratives throughout the program. People with multiple sclerosis who reviewed the program gave feedback that the program was relatable, feasible, and acceptable. Experts agreed that the program appropriately represented the main tenets of mindfulness. Iterative feedback was used to further refine the program. CONCLUSIONS: The web-based mindfulness program that we developed was viewed positively by both experts and end users. The program reflects common concerns for people with multiple sclerosis and has the potential to meet important unmet psychological needs. A randomized controlled trial was planned to determine the efficacy of the program.

The evaluation of an online mindfulness program for people with multiple sclerosis: study protocol.

BACKGROUND: Multiple sclerosis (MS) is a neurological disease of the central nervous system and is associated with many psychosocial symptoms that are difficult to manage including low mood, anxiety, fatigue and pain, as well as low health-related quality of life. Internet-based psychosocial interventions that use mindfulness-based approaches are gathering much attention in recent literature, particularly in the treatment of chronic illnesses. However, no large randomized controlled trials have been done examining the efficacy of such interventions for people with MS (PwMS). METHODS/DESIGN: This study is a randomised controlled trial of an online mindfulness-based intervention (MBI) for PwMS. Participants will be randomised to receive either the MBI or offered the intervention after a waiting period. All participants will be assessed to determine whether they have a history of recurrent depressive disorder. The primary outcome will be severity of depression, according to the Centre of Epidemiology Depression Scale. Secondary outcomes will be anxiety severity, fatigue, pain and quality of life. Assessments will be conducted pre, post-treatment, at three and six-month follow-up. The online mindfulness-based program was developed in collaboration with end-users (n = 19 PwMS) who gave feedback about what would be feasible and acceptable, and the draft program was reviewed by both experts and patients. DISCUSSION: Multiple sclerosis is the most common acquired chronic neurological disease amongst young adults and is associated with a range of symptoms that can be difficult to cope with. In face-to-face interventions, a MBI demonstrated the largest effect in a recent meta-analysis of psychological treatments for PwMS, but MBIs for PwMS have not been delivered online. Hence, this trial will confirm whether MBIs can be efficacious when delivered online. A range of symptoms are assessed as outcomes so that the nature of benefits associated with the online MBI can be ascertained. TRIAL REGISTRATION: ACTRN12618001260213 .

Efficacy of Psychosocial Interventions for People with Multiple Sclerosis: A Meta-Analysis of Specific Treatment Effects.

BACKGROUND: Psychosocial interventions are often used as an adjunct to the medical management of multiple sclerosis (MS). However, the efficacy of such approaches for a range of psychosocial indications remains unclear. OBJECTIVE: To determine the efficacy of psychosocial therapies for people with MS (PwMS). METHODS: We searched 6 electronic databases (Medline, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL, and Clinicaltrials.gov) until April 21, 2016, for randomized controlled trials reporting the effect of psychological interventions for depressive symptoms, anxiety, pain, fatigue, or health-related quality of life (HRQoL) in PwMS. RESULTS: The search yielded 356 articles with 13 included studies (n = 1,617). Benefits of psychological interventions were found for depressive symptoms (Cohen's d = 0.281), anxiety (d = 0.285), fatigue (d = 0.228), and mental (d = 0.398) and total HRQoL (d = 0.444), but not physical HRQoL. There were insufficient studies to meta-analyze posttreatment outcomes for pain. Interventions were more effective for HRQoL for patients with relapsing-remitting MS and when treatment doses were larger. Cognitive behavioral therapy (CBT) was not efficacious for PwMS when considered alone. CONCLUSION: Psychosocial interventions have a significant, positive impact across a range of outcomes for PwMS with small, yet consistent, effect sizes. There was some indication that CBT was less efficacious than other interventions. However, this may be due to smaller treatment doses in CBT studies.
