• Sex: All
• Target Recruitment: 80

Inclusion Criteria

Inclusion criteria for the chronic pain sample are: that the participant has had pain for at least six months; and be fluent in English so they can complete the English-language validated questionnaire measures. Inclusion criteria for the matched, pain-free sample are the same as the chronic pain sample, with the exception of not experiencing more than seven consecutive days of pain within the last month.

Exclusion Criteria

Exclusion criteria identify those participant characteristics that might lead to adverse effects from the weight-lifting task or confound interpretation of the study findings. These criteria apply equally to both the chronic-pain and matched control samples. Exclusion criteria include: physical comorbidities that might hinder participation, such as facial nerve pathology that prevents emotional expression and mobility issues that have not been adequately addressed in the study design; psychological comorbidities that expert clinicians judge as possibly leading to adverse pain experiences, emotional distress or that confound interpretation of findings (e.g. psychosis, disorders of thought or disorders of motivation); and clinically identified severe health complications (e.g. cancers) from which study participation may cause needless distress and that would also could confound interpretation of findings.

Primary Outcome Measures

Name	Time	Method
Emotional regulatory skill as assessed by speed and accuracy of posing facial expressions of emotion. Participants will be prompted to make these expressions and a webcam will record these expressions. Participants will press a key to take a photo when they decide they are posing that particular expression. Speed will be determined by the delay between stimuli presentation and this key press.<br><br>The expression photos will be rated for accuracy to an emotional prototype using a 0 to 3 scale, with 3 indicating perfect reproduction of the expression. At least two people will code the expressions with degree of inter-rater agreement determining the final rating for the expression. If agreement cannot be obtained then the expression will be removed from the dataset.[Immediately after the weight-lifting task whilst discomfort still has a detectable effect on emotional-regulatory skill.]
