Gaining insights on the influence of attention, anxiety, and anticipation on pain perception
Purpose: This article highlights the influence of attention and pain anticipation on pain attenuation. Pain-related trait anxiety was found to moderate the effect that attention strategies impose on pain perception. This article may contribute to clinical treatments quality, where pain attenuation effect is desired.
Participants and methods: One hundred seven participants, comprising of 72 (67%) females and 35 (33%) males between the age of 17 and 48 (M=22.6, SD =4.36), were used in the analysis. The current study measured the effect of pain anticipation and attention on three aspects of pain perception: threshold, tolerance, and perceived pain intensity. Pain anticipation was manipulated by varying the amount of information given to participants about a future pain stimulus. Attention was manipulated through a sensory focusing task and a distraction task. Participants were randomized into 1) InfoControl group with distraction task trial (n=30), 2) InfoControl group with attention to pain trial (n=26), 3) InfoExtra group with distraction task trial (n=26), or 4) InfoExtra group with attention to pain trial (n=25). The pain stimulus was delivered in a form of heat. The moderating effects of pain-related trait anxiety on these variables were also investigated using Pain Anxiety Symptom Scale Short Form.
Results: Two structural equation models revealed that anticipation is not a predictor of pain perception and neither did it interact with pain-related trait anxiety. However, attention strategies do significantly relate to pain perception. Furthermore, pain-related anxiety was a significant moderator of attention and pain attenuation. These findings imply that the effectiveness of attention strategies in attenuating pain is affected by individuals' pain-related trait anxiety.
Conclusion: The results suggest the importance of appointing the appropriate attention strategy to different individuals with varying level of trait anxiety. Future explorations are necessary to develop a more specific understanding on the nature of information and distractions on pain perception
The effects of mindfulness-based interventions on symptoms of depression, anxiety, and cancer-related fatigue in oncology patients: A systematic review and meta-analysis.
ObjectiveMindfulness-based interventions (MBIs) are increasingly being integrated into oncological treatment to mitigate psychological distress and promote emotional and physical well-being. This review aims to provide the most recent evaluation of Mindfulness-Based Stress Reduction (MBSR), Mindfulness-Based Cognitive Therapy (MBCT), and Mindfulness-Based Cancer Recovery (MBCR) treatments, in reducing symptoms of depression, anxiety and CRF in oncology populations.MethodsA search using the following search terms was conducted: (mindful* OR mindfulness* OR mindfulness-based* OR MBI* OR MBCT OR MBSR OR MBCR) AND (Oncol* OR cancer OR neoplasm OR lymphoma OR carcinoma OR sarcoma) to obtain relevant publications from five databases: PsycINFO, PubMed, Embase, and MEDLINE by EC, and ProQuest Dissertations & Theses Global from January 2000 to February 2022. 36 independent studies (n = 1677) were evaluated for their overall effect sizes (using random-effects models), subgroup analyses, and quality appraisals. Evaluations were performed separately for non-randomized (K = 20, n = 784) and randomized controlled trials (K = 16, n = 893).ResultsThe results showed that MBIs have significant medium effects in reducing symptoms of depression (Hedges' g = 0.43), anxiety (Hedges' g = 0.55) and CRF (Hedges' g = 0.43), which were maintained at least three months post-intervention. MBIs were also superior in reducing symptoms of anxiety (Hedges' g = 0.56), depression (Hedges' g = 0.43), and CRF (Hedges' g = 0.42) in oncology samples relative to control groups. The superiority of MBIs to control groups was also maintained at least three months post-intervention for anxiety and CRF symptoms, but not for depressive symptoms. The risk of bias of the included studies were low to moderate.ConclusionsThis review found that MBIs reduced symptoms of depression, anxiety and CRF in oncology populations.Systematic review registrationPROSPERO: International Prospective Register of Systematic Reviews: CRD42020143286
