Several person variables predate injury or pain onset that increase the probability of maladjustment to pain and opioid misuse. The aim of this study was to evaluate the role of 2 diathesis variables (impulsiveness and anxiety sensitivity [AS]) in the adjustment of individuals with chronic noncancer pain and opioid misuse. The sample comprised 187 individuals with chronic noncancer pain. The hypothetical model was tested using correlation and structural equation modeling analyses. The results show a significant association between impulsiveness and AS and all the maladjustment variables, and between impulsiveness and AS and opioid misuse and craving. However, although the correlation analysis showed a significant association between adjustment to pain and opioid misuse, the structural equation modeling analysis showed a nonsignificant association between them (as latent variables). The findings support the hypothesis that both impulsiveness and AS are vulnerability factors for maladaptive adjustment to chronic pain and opioid misuse. PERSPECTIVE: This article adds to the empirical literature by including AS and impulsiveness as antecedent variables in a model of dual vulnerability to chronic pain maladjustment and opioid misuse. The findings suggest the potential utility of assessing both factors in individuals in the first stages of chronic pain., (Copyright © 2024 United States Association for the Study of Pain, Inc.

This international multicenter randomized controlled trial aimed to compare the effectiveness of virtual reality (VR) distraction with an identical non-VR game in reducing needle-related pain and anxiety in children undergoing venous blood draw. The study involved 304 children aged 5-9 years undergoing a blood draw procedure, randomly allocated to one of three groups: VR distraction, non-VR distraction, and control group (usual care). The distraction task was based on the Multiple Object Tracking (MOT) paradigm, and the game was identical in design and gameplay for both VR and non-VR distraction groups. The primary outcome was self-reported pain intensity using the Faces Pain Scale-Revised (FPS-R). Secondary outcomes included child distress, attention/distraction to the blood draw, and parent and medical staff satisfaction with procedure. Analyses were conducted using analysis of variance and multivariable linear regression models. The results showed that VR distraction and non-VR distraction performed similarly, showing large effect sizes compared with standard care. There was no significant difference between the two types of distraction. The study's findings suggest that VR and non-VR distraction are similarly effective in reducing needle-related pain and anxiety in children undergoing venous blood draw. This is the first well-powered study comparing modern VR distraction with an identical task displayed on a smartphone or monitor screen. The study's results have important implications for using VR in clinical settings and suggest that investing in expensive VR equipment for acute pain management may not be necessary.

Background: The PASS-20 is a general measure of pain-related anxiety and fear. The aim of the present study was to adapt the questionnaire for use in Spanish-speaking populations., Methods: Sample 1 comprised 216 individuals with chronic spinal pain (114 women and 102 men); sample 2 comprised 85 individuals with acute spinal pain (62 women and 23 men). The dimensionality of the PASS-20-SV items was evaluated using Exploratory Factor Analysis and an optimal implementation of Parallel Analysis (robust maximum likelihood). Data from sample 1 was used to analyse internal consistency and convergent validity. Estimated test-retest stability and predictive validity were based on data from the sample 2 participants, who completed the first administration (T1) and a second administration (T2, 6 months later)., Results: The PASS-20-SV comprises two factors: pain-related anxiety and apprehension, and pain-related fear and avoidance. It has good to excellent reliability and adequate test-retest stability. The results support its convergent and predictive validity., Conclusions: The Spanish Version of the PASS-20 is a valid, reliable measure of pain-related anxiety and pain-related fear in Spanish-speaking patients.

The aim of this study was to validate the Spanish version of the Defensive Pessimism Questionnaire. A sample of undergraduate students (N = 539) was measured on defensive pessimism using the Defensive Pessimism Questionnaire (DPQ), optimism and pessimism using the Life Orientation Test (LOT), positive and negative affect using the Positive and Negative Affect Schedule, and anxiety using the trait subscale of the State and Trait Anxiety Inventory. A Spanish version of the DPQ (DPQ-SV) is presented. Exploratory and Robust Confirmatory Factor Analysis had a bi-dimensional structure (Reflectivity and Negative Expectation). Omega coefficient showed a high internal consistency and the temporal stability was high in each dimension. Both DPQ-SV subscales (Negative Expectation and Reflectivity) showed adequate convergence with LOT-optimism and LOT-pessimism. Reflectivity showed adequate criterion validity with trait-anxiety and negative affect, but inadequate criterion validity with positive affect. Negative Expectation showed excellent criterion validity with trait-anxiety and negative affect and good criterion validity with positive affect. Finally, mediation analysis showed that Negative Expectation had a significant indirect mediating effect between trait-anxiety and negative affect. Reflectivity had a significant indirect mediating effect between trait-anxiety and negative and positive affect. Analysis of the psychometric properties of the DPQ-SV subscale scores showed that it is a two factor adequate measurement tool for its use in this type of samples., Competing Interests: The authors have declared that no competing interests exist.

Objective Substantial empirical evidence has shown that intolerance of uncertainty is a central transdiagnostic feature in psychopathology and it has been suggested to be a pain-related psychological factor contributing to the experience of chronic pain. However, research in this area is virtually nonexistent. The objective of this study was to investigate associations between pain severity, catastrophizing, and anxiety in people with chronic nononcological pain, while assuming that intolerance of uncertainty moderates these relationships. Methods A convenience sample of 188 individuals with nononcological chronic pain (157 women and 32 men) participated in the study. We investigated the moderated mediation of intolerance of uncertainty between anxiety and catastrophizing and between catastrophizing and pain intensity. Results The full moderated mediation model accounted for significant variance in pain intensity (R2 = 0.148, P <.001). Intolerance of uncertainty significantly moderated the interaction between anxiety and catastrophizing (B = 0.039, SE = 0.012, 95% CI [0.015, 0.063]) and between catastrophizing and pain intensity (B = -0.034, SE = 0.010, 95% CI [−0.054, −0.014]). Anxiety and intolerance of uncertainty did not interact in predicting catastrophizing, although an interaction effect was found between intolerance of uncertainty and catastrophizing in predicting pain intensity. Conclusion This study is the first to address the interrelationship of intolerance of uncertainty, catastrophizing, and anxiety in relation to perceived pain intensity. The current findings support intolerance of uncertainty as a relevant psychological variable that is distinct from other relevant constructs in the setting of pain research and treatment.

Objectives: The identification of psychological markers of the posttraumatic stress reaction after a cardiac event is relevant in the management of cardiovascular risk factors. The aim of the study to test the contribution of experiential avoidance, anxiety sensitivity, and depressive symptoms to acute coronary syndrome posttraumatic stress symptoms and perceived health (both measured 6 months later), and to determine whether the associations between experiential avoidance, anxiety sensitivity, and depressive symptoms with perceived health were mediated by the posttraumatic stress symptoms. Design: 180 patients with acute coronary syndrome completed a survey over a 6-month period. Results: Anxiety sensitivity and depressive symptoms but not experiential avoidance contributed significantly to posttraumatic stress symptoms. Depressive symptoms and posttraumatic symptoms but neither anxiety sensitivity nor experiential avoidance had a significant association on perceived health. Acute coronary syndrome posttraumatic symptoms significantly mediated the association of depressive symptoms with perceived health. That is, increased depressive symptoms was significantly associated with higher levels of posttraumatic symptoms, which in turn predicted lower levels of perceived health. Conclusions: Understanding the psychological factors that are associated with post-acute coronary syndrome posttraumatic stress symptoms may help to identify patients at risk in order to refer them to the appropriate psychological care service.

To analyze the factorial structure and psychometric properties of the Spanish adaptation of the AEQ, and to validate it by reporting relevant pain-related variables, which were not investigated in the original study. One hundred and fifty Spanish patients diagnosed with chronic back and neck pain were referred by physicians from different pain clinics in Spain; all the patients filled out the questionnaires at their clinic. A series of principal components analyses (PCA) was performed to develop the Spanish version of the AEQ. Reliability and validity were also calculated. The PCAs revealed five fear-avoidance scales (Kaiser-Meyer-Olkin measures were between .60 and .88, and Bartlett's tests were significant, p < .01): the Depression scale (DS), Anxiety scale (AS), Catastrophizing scale (CS), Helplessness/hopelessness scale (HHS), and Avoidance of Social and Physical Activities scale (ASPAS), and three endurance-related responses scales: Pain Persistence Behaviour and Distraction scale (PPDS), Ignoring Pain scale (IPS), and Humor scale (HS). All the scales showed high internal consistency (α > .73) and suitable validity (p < .05). New results associated with pain-related cognitive/affective and behavioural responses are discussed. This instrument will probably help clinicians to identify Spanish patients at a high risk of chronicity and to develop treatments tailored to the different profiles in order to improve secondary and tertiary prevention in back and neck pain.

The Flourishing Scale was developed by Diener based on recent theories of psychological wellbeing. This article tested some of the psychometric properties of the Spanish version of the Flourishing Scale (FS-SV). Participants were 545 university students (Sample 1) and 111 patients with chronic back pain (Sample 2). Participants completed a battery of instruments to assess flourishing, trait-anxiety, dispositional optimism, dispositional pessimism, and positive and negative affect. In both samples, the results of Principal Axis Factor and Simultaneous Component Analyses showed that the FS-SV scores had a common unidimensional structure. The Omega coefficient showed high reliability for scale scores. The generalizability of the FS-SV structure was analysed using Confirmatory Factor Analysis. Test-retest reliability, criterion validity, and models that included flourishing as a mediator of the associations between personality variables and positive and negative affect were analysed in Sample 1. Results provided support for a single construct in both samples. Flourishing appeared as a mechanism that may account for the association between anxiety, optimism, pessimism, and positive affect. In line with previous studies, these findings extend the concept of flourishing. [ABSTRACT FROM AUTHOR]
