Emotional reactions to pain predict psychological distress in adult patients with Sickle Cell Disease (SCD)

A Systemic Review of the Psychosocial Aspects of Chronic Pain in Youth With Sickle Cell Disease

OBJECTIVES

The psychosocial aspects of chronic pain among youth with sickle cell are poorly described and may be better understood within a biopsychosocial model of chronic pain as applied to youth living with sickle cell disease.

DESIGN

A systematic literature review was performed to synthesize the psychosocial factors contributing to chronic pain in this population. Criteria for study inclusion were primary quantitative research studies focused on psychosocial aspects of chronic pain among youth with sickle cell disease.

DATA SOURCES

PubMed, CINAHL, PsychINFO, and Scopus were searched for relevant articles.

REVIEW/ANALYSIS METHODS

Articles selected for full-text review were appraised for quality using the Joanna Briggs Institute Quality Appraisal Tools. Thirteen articles were included.

RESULTS

Depression, anxiety, pain catastrophizing, pain coping, executive functioning, and functional impairment were prevalent in youth living with sickle cell disease and chronic pain. Research gaps included the influence of stigma, injustice, peer interactions, and school and work on chronic pain.

CONCLUSIONS

The biopsychosocial model of chronic sickle cell disease-related pain for youth was developed and modified based on the results of this systematic review to remind clinicians of the various factors to consider in clinical practice and spur additional research in this field.

Psychiatric comorbidities in adults with sickle cell disease: A narrative review

Although descriptions of quality of life and patient reports of mood in sickle cell disease (SCD) have become more common in the literature, less is known about psychiatric illness prevalence, presentation, and treatment, particularly for adults. We provide a narrative review of what is known about common and debilitating psychiatric conditions such as depression, anxiety, and cognitive impairment, specifically for adults with SCD. We discuss the limitations of the current evidence, make provisional recommendations, and identify opportunities for research and improved care.

Sickle Cell Disease, More Than Just Pain: The Mediating Role of Psychological Symptoms

OBJECTIVES

Perceived stress is associated with sickle cell disease (SCD) pain; however, little is known about psychological mechanisms that may clarify this link among adult patients. This study explored whether anxiety and depression symptoms explained the relation between perceived stress and SCD pain episode frequency among 70 African-American adults (51.4% women, mean age 35.6 years).

METHODS

Participants completed measures of perceived stress, pain, and psychological symptoms in an outpatient clinical setting.

RESULTS

A serial multiple mediation model showed that psychological symptoms collectively reduced the association between perceived stress and SCD pain frequency (b = 0.116, P = 0.141). However, only the indirect effect of stress on pain frequency through anxiety symptoms was significant (b = 0.089).

CONCLUSIONS

Anxiety but not depression symptoms best explain the association between stress and SCD pain. Further research is needed to identify the specific components of negative affect that drive the experience of SCD pain.
