A systematic review with subset meta-analysis of studies exploring memory recall biases for pain-related information in adults with chronic pain.

ABSTRACT: Pain-related memory biases have been frequently explored in individuals with chronic pain, and along with attentional and interpretation biases are hypothesised to contribute to the onset and/or maintenance of chronic pain. The aim of this review is to provide a systematic review and synthesis of studies exploring memory recall biases for pain-related information in individuals with chronic pain relative to healthy controls and the recall of neutral information. Studies were identified through a search of Medline, PsychINFO, Web of Science, CINAHL, Cochrane Library, and Open Grey databases. Search terms were memory, recall, recognition, and bias*, intersected with pain. Eighteen studies meeting the inclusion criteria were included. Subset meta-analyses are also reported from 12 studies with relevant between-groups data (comparing recall in chronic pain vs healthy control groups) and 12 studies with relevant within-groups data (eg, comparing recall of pain-related/emotional vs neutral words). Between-groups analysis revealed significantly weaker recall bias for affective-pain words in individuals with chronic pain relative to healthy controls, but only when nondepressed chronic pain individuals were included. No significant differences were found between groups in the recall of sensory-pain, illness-related, or depression-related words. Within-groups analysis revealed individuals with chronic pain show a significant recall bias favouring sensory-pain words relative to neutral and affective-pain words, and a bias for illness-related words relative to depression-related words. A recall bias favouring neutral words was found in healthy individuals. Evidence for the presence of pain-related memory biases in patients with chronic pain is inconclusive. Further methodologically rigorous research is required.

Project description:Despite the spectacular success of vaccines in preventing infectious diseases, fears about their safety and other anti-vaccination claims are widespread. To better understand how such fears and claims persist and spread, we must understand how they are perceived and recalled. One influence on the perception and recall of vaccination-related information might be universal cognitive biases acting against vaccination. An omission bias describes the tendency to perceive as worse, and recall better, bad outcomes resulting from commissions (e.g. vaccine side effects) compared to the same bad outcomes resulting from omissions (e.g. symptoms of vaccine preventable diseases). Another factor influencing the perception and recall of vaccination-related information might be people's attitudes towards vaccines. A confirmation bias would mean that pre-existing pro-vaccination attitudes positively predict perceptions of severity and recall of symptoms of vaccine preventable diseases and negatively predict perceptions of severity and recall of vaccine side effects. To test for these hypothesized biases, 202 female participants aged 18-60 (M = 38.15, SD = 10.37) completed an online experiment with a between-subjects experimental design. Participants imagined that they had a 1-year old child who suffered from either vaccine side effects (Commission Condition) or symptoms of a vaccine-preventable disease (Omission Condition). They then rated a list of symptoms/side effects for their perceived severity on a 7-point Likert scale. Finally, they completed a surprise recall test in which they recalled the symptoms/side effects previously rated. An additional scale was used to measure their attitudes towards vaccines. Contrary to the hypotheses, perceptions of severity and the recall of symptoms/side effects were not associated with experimental condition, failing to support the omission bias, nor did they interact with attitudes towards vaccines, failing to support the confirmation bias. This cast doubt on the possibility that the spread of anti-vaccination claims can be explained by these particular universal cognitive biases.

Project description:BackgroundChildren of chronic pain patients run greater risk for developing chronic pain themselves. Exposure to chronic pain of the parent might install cognitive (e.g., pain catastrophizing, interpretation and attentional bias) and affective (e.g., pain anxiety) vulnerability which increase the risk for the development of chronic pain complaints in offspring. This study examines whether pain-free offspring of parents with chronic pain complaints make more health-threatening interpretations and display a stronger pain-related attentional bias compared to the offspring of pain-free parents. We furthermore examined differences between both groups on pain catastrophizing, pain anxiety and somatic symptoms and explored the relations between parental pain catastrophizing and aforementioned pain vulnerability measures in offspring.MethodsOffspring of parents with chronic pain complaints (n = 24) and pain-free parents (n = 27) completed measures of attentional bias (i.e., pictorial dot probe), interpretation bias (i.e., ambiguous word association task), pain catastrophizing, pain anxiety and somatic symptoms. Parents completed measures of pain catastrophizing and psychological distress.ResultsNo differences between offspring of parents with and without pain complaints were observed on pain catastrophizing, pain anxiety and somatic symptoms. Both groups of healthy adolescents predominantly showed benign, non-health-threatening interpretations. Children of pain-free parents showed an attention bias for pain stimuli, while offspring of parents with pain complaints showed no such bias.ConclusionsFuture research is needed to further elucidate the precise role of parental pain in the development of pain-related biases and the significance of these biases in the onset and/or maintenance of a chronic pain condition in children and adolescents.SignificanceParental chronic pain may install psychological vulnerability for developing chronic pain and associated complaints in offspring. This study did not show differences in pain-directed attentional and interpretation bias between offspring of parents with chronic pain complaints and offspring of pain-free parents. Further (longitudinal) research is needed to elucidate the precise role of parental pain factors in the development of pain-related vulnerability in offspring of chronic pain parents, thereby identifying important targets for the prevention and early intervention of chronic pain.
