Anxiety, Reinforcement Sensitivity and Social Context in Accepting the Experience of Pain Among Rheumatoid Arthritis Patients.

Background: Acceptance has become one of the most widely studied processes regarding chronic pain because of its ability to influence participants' adaptation and coping responses. Leading researchers have found relationships between variables such as anxiety, reinforcement sensitivity, and the responses of the participants' environment to their behavior and acceptance. In contrast, few studies have been found that investigate the variables that predict the acceptance of pain. This study has set out to explore the relationships between pain-related anxiety, sensitivity to contingencies, and the punishment responses of significant people toward pain behaviors regarding pain acceptance. Methods: With a view to fulfilling this purpose, a cohort of 62 participants with rheumatoid arthritis was chosen, and the subjects were assessed through the following self-report measures: Chronic Pain Acceptance Questionnaire, CPAQ; Pain Anxiety Symptoms Scale, PASS-20; The Sensitivity to Punishment and Sensitivity to Reward Questionnaire, SPSRQ, and The West Haven-Yale Multidimensional Pain Inventory, WHYMPI. The study's initial objectives were achieved by means of a stepwise multiple linear regression analysis. Results: The linear regression analyses revealed a negative and significant correlation between anxiety, reinforcement sensitivity, and the significant persons' responses to pain behaviors and pain acceptance. Conclusion: The results suggest that the identification of these variables might be important for addressing these participants' pain. Finally, the discussion focuses on our findings' implications as regards their use in clinical practice.

Emotional affection on a sustained attention task: The importance the aging process and depression.

Chronic pain is a complex experience that has now become a major public health issue. This has prompted many researchers to study attention, understanding it to be a crucial factor that allows altering the experience of pain, while attributing considerable importance to sustained attention. Accordingly, the main studies in this field stress the importance of emotion regulation processes and emotions on the perception of painful stimuli and attentional processes themselves. Nevertheless, only a handful of studies have been found that directly study the relationship between these variables. Within this context, this article sets out to analyse emotional regulation processes, emotional variables (depression and anxiety), the experience of pain, and age on the ability to maintain the vigilance response in a sample of patients with chronic pain. This involved selecting a sample of 49 patients with rheumatoid arthritis and examining their performance in an ad-hoc sustained attention test. With a view to complying with the study's main purpose, the participants were also assessed through the use of the following self-report measures: the Beck Depression Inventory (BDI-I); the Hospital Anxiety and Depression Scale (HADS); the McGill Pain Questionnaire, and the Difficulties in Emotion Regulation Scale (DERS). Linear regression analyses revealed a significant impact of the aging process on the performance times in the attention task. Likewise, age and depression recorded a significant correlation with the mistakes made during the task. These results suggest that higher depression levels and an older age might be related to a worse adaptation to pain management techniques based on attention processes, such as mindfulness.

The Impact of Cognitive Anxiety and the Rating of Pain on Care Processes in a Vigilance Task: The Important Part Played by Age.

Chronic pain is a serious public health problem that has grown exponentially in recent years, which is why it has received the attention of numerous researchers. Most of the studies in the field of chronic pain have focused on care as a mediating variable on the perception of painful stimuli and emotions. Nevertheless, there are very few studies that have gone in the opposite direction. This study's aim is therefore to analyse the impact of emotional variables (anxiety and depression), the rating of pain, and age on vigilance processes in a sample of patients with chronic pain. To do so, the attentional performance of a cohort of 52 patients with chronic pain was measured through the use of a modified dot-probe task. Furthermore, all the participants were evaluated using the following self-report measures: Beck's Depression Inventory-II (BDI-II), the McGill Pain Questionnaire, and the Pain Anxiety Symptoms Scale-20 (PASS-20). Stepwise multiple linear regression analysis revealed a significant negative correlation between the pain rating index and the number of mistakes the participants made during the attention test. There was also a positive and significant correlation with age and another negative and significant correlation with cognitive anxiety regarding the overall performance times during the undertaking of the experimental task. These results point to the importance of a more in-depth understanding of the impact that the emotional variables and other variables such as age have on attentional processes and the rating of pain. Finally, the discussion focuses on the implications these results could have for clinical practice or for future research studies in this field.

The role of rumination in the guilt associated with bereavement according to cause of death.

The purpose of this study was to analyse the role rumination plays in the relationship between cause of death and the guilt present during bereavement. The sample consisted of 90 people that had suffered a loss due to an expected or unexpected natural death, suicide or accident. The results suggest that rumination increases the levels of guilt felt by people that had suffered a loss due to suicide compared to those whose loss was due to an expected natural death. These findings contribute to a better understanding of the mechanisms with an influence on bereavement.

Influence of patient personality in the treatment of rheumatoid arthritis.

Individualized treatment of rheumatoid arthritis (RA) based on genetic/serologic factors is increasingly accepted. Moreover, patients are more actively involved in the management of their disease. However, personality has received little attention with respect to perception of the need and adherence to treatment. Our objective was to evaluate whether patient personality was associated with the acceptance or rejection of more aggressive early treatment. We performed a cross-sectional study in two hospitals with early arthritis clinics where sociodemographic, clinical, and therapeutic variables are systematically recorded. Patients completed Eysenck Personality Questionnaire, Multidimensional Health Locus of Control, Pain-Related Self-Statement Scale and Pain-Related Control Scale. Aggressive treatment was considered if patients received more than two DMARDs or biological agents during the first year of follow-up. Multivariate logistic regression analysis was performed to determine predictors of aggressive treatment. One hundred seventy-six RA patients were included (80 % women, disease begin median age 55 years). Treatment was considered aggressive in 57.9 % of the sample. Scores were high in extraversion in 50.8 % of patients, neuroticism in 29.5 % and psychoticism in 14.7 %. Neuroticism was the only factor associated with aggressive treatment, which was less probable (p = 0.04, OR = 0.40). Neuroticism also decreased the possibility of receiving a combination of biologics and DMARDs (p = 0.04, OR = 0.28). Patients with high scores on neuroticism are more worried, obsessive and hypochondriac, leading them to reject more aggressive therapy. It is important to educate about their disease so that they will accept more aggressive approaches in clear cases of poor outcome.

Trends in scientific literature on atypical antipsychotics in South Korea: a bibliometric study.

OBJECTIVE: We have carried out a bibliometric study on the scientific publications in relation to atypical or second-generation antipsychotic drugs (SGAs) in South Korea. METHODS: With the EMBASE and MEDLINE databases, we selected those publications made in South Korea whose title included the descriptors atypic(*) (atypical(*)) antipsychotic(*), second-generation antipsychotic(*), clozapine, risperidone, olanzapine, ziprasidone, quetiapine, sertindole, aripiprazole, paliperidone, amisulpride, zotepine, asenapine, iloperidone, lurasidone, perospirone and blonanserin. We applied some bibliometric indicators of paper production and dispersion with Price's law and Bradford's law, respectively. We also calculated the participation index (PI) of the different countries, and correlated the bibliometric data with some social and health data from Korea (such as total per capita expenditure on health and gross domestic expenditure on research and development). RESULTS: We collected 326 original papers published between 1993 and 2011. Our results state fulfilment of fulfilled Price's law, with scientific production on SGAs showing exponential growth (correlation coefficient r=0.8978, as against an r=0.8149 after linear adjustment). The most widely studied drugs were risperidone (91 papers), aripiprazole (77), olanzapine (53), and clozapine (43). Division into Bradford zones yielded a nucleus occupied by the Progress in Neuro-Psychopharmacology and Biological Psychiatry (36 articles). A total of 86 different journals were published, with 4 of the first 10 used journals having an impact factor being greater than 4. CONCLUSION: The publications on SGAs in South Korea have undergone exponential growth over the studied period, without evidence of reaching a saturation point.

El dolor en los pacientes con artritis reumatoide: variables psicológicas relacionadas e intervención / Pain in patients with rheumatoid arthritis: psychological variables and interventions

El dolor es un síntoma principal en los pacientes con Artritis Reumatoide (AR), generalmente determinando su ajuste a la enfermedad y su calidad de vida global. Este artículo presenta una revisión y discusión sobre el dolor en pacientes con AR desde un enfoque psicológico basado en las investigaciones recientes. Se repasan los trabajos que han evaluado las emociones negativas en los pacientes con AR, aquellos que han explorado y explicado su papel sobre el dolor del enfermo, así como un compendio de las técnicas psicológicas más efectivas para el manejo del dolor. Las conclusiones muestran que el dolor es un problema central en los pacientes con AR. Las emociones negativas, que parecen estar presentes de forma más marcada en los pacientes con AR que en la población sana, son predictores significativos del dolor. Por otra parte, los estudios sugieren que el enfoque cognitivo-conductual es eficaz para los pacientes con AR en la mejora no sólo del dolor sino también en el ajuste psicológico a la enfermedad, mostrando un beneficio adicional para los pacientes con AR que reciben tales intervenciones como complemento del cuidado médico habitual. Para el futuro, el artículo sugiere la necesidad de realizar más estudios sobre los patrones de emocionalidad negativa y estrategias de afrontamiento es muestras españolas (AU)

Pain is a key symptom in patients with rheumatoid arthritis (RA), usually determining the patient’s adjustment to illness and his/her overall quality of life. Based on recent research, this article provides a review and discussion of RA pain from a psychological approach. Negative emotions and their relations to pain are assessed, and the most effective psychological techniques for pain management are described. It is concluded that pain is a key symptom in RA patients, being frequently predicted by negative emotions –which are more prevalent in RA patients than in the general population. Moreover, studies suggest that the cognitive-behavioural approach is effective in RA patients since it improves not only the pain but also the psychological fit to the disease, being an additional benefit for RA patients when this approach adds to the standard medical care. With a view to the future, this paper suggests the need of further studies with Spanish samples on negative emotions and coping skills patterns related to pain (AU)
