We investigated the role of the child’s pain catastrophizing in explaining (1) children’s self-reported tendency to verbally share their pain experience with others and (2) different dimensions of pain expression, as described by the mother and the father, including non-verbal and verbal communicative pain behaviour and protective pain behaviour. Participants were school children, children with chronic...
The experience of pain is believed to be influenced by social, cultural, environmental, psychological, and genetic factors. Despite this assertion, few studies have included clinically relevant pain phenotypes when investigating interactions among these variables. This study investigated whether psychological variables specific to fear-avoidance models and catechol-O-methyltransferase (COMT) genotype...
This experiment investigated the effects of child catastrophic thinking and parental presence on the facial expressions of children when experiencing pain. School children experienced pressure pain in either one of two conditions: (1) when observed by a parent (n=53 children and their parent), or (2) when observed by an adult stranger (n=31 children). Analyses revealed that children showed more facial...
Recent research suggests that communicative and protective pain behaviors represent functionally distinct subsystems of behavior associated with pain. The present research examined whether components of pain experience such as pain severity, catastrophizing and fear of pain were differentially associated with communicative and protective pain behaviors. It was predicted that pain severity would be...
Previous research supports the fear-avoidance model in explaining the transition from acute to chronic non-specific musculoskeletal pain. However, there is still little knowledge on when this vicious circle of pain, disability, pain catastrophizing and fear of movement starts. We performed a daily diary study in 42 patients with acute whiplash injury. Pain, disability, pain catastrophizing and fear...
Pain catastrophizing has recently been suggested to have a social function based on a positive association observed with facial responsiveness to noxious stimulation. However, this assumption is based on studies applying nociceptive stimuli of fixed intensity, such that high catastrophizers not only displayed increased pain behavior but also rated the stimulation as being more painful. The aim of...
Psychological factors consistent with fear-avoidance models are associated with the development of chronic low back pain (LBP). As a result, graded activity (GA) and graded exposure (GX) have been suggested as behavioral treatment options. This clinical trial compared the effectiveness of treatment-based classification (TBC) physical therapy alone to TBC augmented with GA or GX for patients with acute...
