It is well known that chronic pain is prevalent, complex to manage, and associated with high costs, in health care and society in general. Thanks to advances in new forms of cognitive behavioral therapy (known as third-wave CBT), currently clinicians and researchers have an empirically validated psychological treatment with increasing research support for the treatment of chronic pain. This treatment is called acceptance and commitment therapy (ACT). The main aim of this paper is to provide a narrative review that summarizes and integrates the current state of knowledge of ACT in the management of chronic pain as well as discuss current challenges and opportunities for progress. Based on the psychological flexibility model, ACT extends previous forms of CBT and integrates many CBT-related variables into six core therapeutic processes. ACT is a process-based therapy that fosters openness, awareness, and engagement through a wide range of methods, including exposure-based and experiential methods, metaphors, and values clarification. To our knowledge, there are three published systematic reviews and meta-analyses that support the effectiveness of ACT for chronic pain and many studies focused on specific processes derived from the psychological flexibility model. There is also promising support for the cost-effectiveness of ACT; however, the current evidence is still insufficient to establish firm conclusions about cost-effectiveness and the most efficient means of delivery. Additional well-designed economic evaluations are needed. Other research aims include delineating the neurobiological underpinnings of ACT, refining available outcome and process measures or develop new ones for ACT trials, and meeting the challenge of wide dissemination and implementation in real-world clinical practice.

Mindfulness has been described as an inherent human capability that can be learned and trained, and its improvement has been associated with better health outcomes in both medicine and psychology. Although the role of practice is central to most mindfulness programs, practice-related improvements in mindfulness skills is not consistently reported and little is known about how the characteristics of meditative practice affect different components of mindfulness. The present study explores the role of practice parameters on self-reported mindfulness skills. A total of 670 voluntary participants with and without previous meditation experience (n = 384 and n = 286, respectively) responded to an internet-based survey on various aspects of their meditative practice (type of meditation, length of session, frequency, and lifetime practice). Participants also completed the Five Facets Mindfulness Questionnaire (FFMQ), and the Experiences Questionnaire (EQ). The group with meditation experience obtained significantly higher scores on all facets of FFMQ and EQ questionnaires compared to the group without experience. However different effect sizes were observed, with stronger effects for the Observing and Non-Reactivity facets of the FFMQ, moderate effects for Decentering in EQ, and a weak effect for Non-judging, Describing, and Acting with awareness on the FFMQ. Our results indicate that not all practice variables are equally relevant in terms of developing mindfulness skills. Frequency and lifetime practice – but not session length or meditation type – were associated with higher mindfulness skills. Given that these 6 mindfulness aspects show variable sensitivity to practice, we created a composite index (MINDSENS) consisting of those items from FFMQ and EQ that showed the strongest response to practice. The MINDSENS index was able to correctly discriminate daily meditators from non-meditators in 82.3% of cases. These findings may contribute to the understanding of the development of mindfulness skills and support trainers and researchers in improving mindfulness-oriented practices and programs.

The purpose of this study was to evaluate the effectiveness of a 12-week multicomponent treatment based on pain neuroscience education, therapeutic exercise, cognitive behavioral therapy, and mindfulness—in addition to treatment as usual—compared with treatment as usual only in patients with fibromyalgia. This randomized controlled trial involved a total of 272 patients who were randomly assigned to either multicomponent treatment (n = 135) or treatment as usual (n = 137). The multicomponent treatment (2-hour weekly sessions) was delivered in groups of 20 participants. Treatment as usual was mainly based on pharmacological treatment according to the predominant symptoms. Data on functional impairment using the Revised Fibromyalgia Impact Questionnaire as the primary outcome were collected as were data for pain, fatigue, kinesiophobia, physical function, anxiety, and depressive symptoms (secondary outcomes) at baseline, 12 weeks, and, for the multicomponent group only, 6 and 9 months. An intention-to-treat approach was used to analyze between-group differences. Baseline differences between responders (>20% Revised Fibromyalgia Impact Questionnaire reduction) and nonresponders also were analyzed, and the number needed to treat was computed. At posttreatment, significant between-group differences with a large effect size (Cohen d > 0.80) in favor of the multicomponent treatment were found in functional impairment, pain, kinesiophobia, and physical function, whereas differences with a moderate size effect (Cohen d > 0.50 and <0.80) were found in fatigue, anxiety, and depressive symptoms. Nonresponders scored higher on depressive symptoms than responders at baseline. The number needed to treat was 2 (95% CI = 1.7–2.3). Compared with usual care, there was evidence of short-term (up to 3 months) positive effects of the multicomponent treatment for fibromyalgia. Some methodological shortcomings (eg, absence of follow-up in the control group and monitoring of treatment adherence, potential research allegiance) preclude robust conclusions regarding the proposed multicomponent program. Despite some methodological shortcomings in the design of this study, the multicomponent therapy FIBROWALK can be considered a novel and effective treatment for patients with fibromyalgia. Physical therapists should detect patients with clinically relevant depression levels prior to treatment because depression can buffer treatment effects. Fibromyalgia is prevalent and can be expensive to treat. This multicomponent treatment could significantly improve the core symptoms of fibromyalgia compared with usual treatment.

Background/Objective ‘Third-wave’ psychotherapies have shown effectiveness for treating psychopathological symptoms such as anxiety and depression. There is burgeoning interest in examining how these therapies’ core constructs produce their therapeutic benefits. This study explores the hypothetical mediating effect of resilience in the impact of mindfulness and self-compassion on anxiety and depressive symptoms. Method: Cross-sectional study design. The sample consisted of 860 Spanish general population participants. The measures included the Mindful Attention Awareness Scale (MAAS), the Self-Compassion Scale (SCS-12), the Connor-Davidson Resilience Scale (CD-RISC) and the Goldberg Anxiety and Depression Scale (GADS). Bivariate correlations were calculated, and path analysis models were performed. Results: Significant correlations were found between the study variables, always in the expected direction (all p values <.001). The path analysis models showed significant direct effects of mindfulness and self-compassion on anxiety and depression symptoms, but the only significant indirect effects through resilience were found on depression (MAAS: β = -.05, 95% CI = -.11 to -.02; SCS-12: β = -.06, 95% CI = -.33 to -.07). Conclusions: Resilience might partially mediate the effect of mindfulness and self-compassion on depression, but not on anxiety.
