Background: Central sensitization (CS), defined as the amplification of neural signaling within the CNS that elicits pain hypersensitivity, is thought be a characteristic of several chronic pain conditions. Maladaptive body awareness is thought to contribute and maintain CS. Less is known about the relationship between CS and adaptive body awareness.Purpose: This cross-sectional study investigated relationships among self-reported adaptive body awareness (Multidimensional Interoceptive Awareness Scale-2; MAIA-2), CS-related symptoms (Central Sensitization Inventory; CSI), and pain intensity and further delineate potential direct and indirect links among these constructs.
Methods: Online surveys were administered to 280 individuals with chronic pain reporting elevated CSI scores. Strategic sampling targeted respondents to reflect the 2010 census. Pearson's correlations characterized overall relationship between variables. Multiple regression analyses investigated potential direct links. A path analysis assessed mediational effects of CS-related symptoms on the relationship between adaptive body awareness and pain intensity. Results: CSI demonstrated strong, inverse correlations with some MAIA-2 subscales, but positive correlations with others. Higher CSI scores predicted greater pain intensity (b = 0.049, p ≤ 0.001). Two MAIA-2 subscales, Not-Distracting (b = −0.56, p ≤ 0.001) and Not-Worrying (b = −1.17, p ≤ 0.001) were unique predictors of lower CSI. Not-Distracting (b = −0.05, p = 0.003) and Not-Worrying (b = −0.06, p = 0.007) uniquely predicted lower pain intensity. CSI completely mediated the relationship between adaptive body awareness and pain intensity [point estimate = −0.04; 95% bootstrap confident intervals (CI) = −0.05 to −0.02].Conclusions: Findings also support future research to explore causal relationships of variables. Findings suggest that frequency of attention to bodily sensations is distinct from cognitive-affective appraisal of bodily sensation, and the two distinct higher order processes may have divergent influences on perceived pain and
Purpose
The Postural Awareness Scale (PAS) was developed among a sample of German speakers to measure self-reported awareness of body posture. The first aim of this study was to conduct an English translation and cross-cultural adaptation of the PAS. The second aim was to assess psychometric properties of the English version of the PAS.
Methods
Forward and backward translations were conducted. The translated scale was then pretested in a small sample of English-speaking adults (n = 30), followed by cognitive interviews. Finally, consensus of the translated scale was achieved among an expert committee (n = 5), resulting in the Postural Awareness Scale-English Version (PAS-E). Psychometric properties of the PAS-E were investigated among a sample of individuals with chronic pain (n = 301) by evaluating factor structure, reliability, and construct validity. Analyses of variance were conducted to calculate differences in PAS-E scores between specific subgroups (pain conditions, sex, and history of mindfulness practice). Linear regression analyses investigated whether the scores on the PAS-E predicted levels of pain, stress, and mood.
Results
The results obtained from an exploratory factor analysis showed a two-factor solution and were supported by a confirmatory factor analysis. The scale demonstrated good internal consistency and satisfactory construct validity. No significant differences related to sex at birth or pain duration were found.
Conclusion
PAS-E demonstrated good psychometric properties, and therefore, can and should be used both for research and clinical practice.
Psychological flexibility relates to various aspects of mental health, including psychological distress and adaptive mental health. The CompACT has been developed to assess psychological flexibility by quantifying psychological flexibility as a multidimensional whole, and by three processes of psychological flexibility including, Openness to Experience (OE), Behavioral Awareness (BA), and Valued Action (VA). The current study examined the unique predictive property of each three process of the CompACT with aspects of mental health. Participants ( N = 593) were a diverse sample of United States adults. Our results found OE and BA significantly predicted depression, anxiety, and stress. OE and VA significantly predicted satisfaction with life, and all three processes significantly predicted resilience. Our results support multidimensional assessment of psychological flexibility when examining aspects of mental health.
