When faced with the problem of pain one can attempt a solution aimed at relief (assimilation) or a solution aimed at acceptance (accommodation). Using this dual process model of adaptation to pain, this study compares acute and chronic pain patients on their approach to problem solving. Three hundred and sixty-four patients were recruited from clinical settings, 303 with chronic pain and 61 with acute pain, and completed a range of measures of both affect and pain-related behavior, including the Pain Solutions Questionnaire. ⋯ Only in the case of catastrophic thinking about pain was it found that the effects of assimilative coping were moderated by pain duration. For chronic pain patients, catastrophic thinking about pain was greater when assimilative coping was higher. These results are discussed within the context of a goal directed motivational model of adaptation to chronic pain.

Attenuation of the lower limb nociceptive flexion reflex (NFR) during the cardiac cycle has been attributed to inhibition of sensorimotor function by arterial baroreceptor activation. It has been proposed that cardiopulmonary baroreceptors might have similar inhibitory effects. ⋯ Nociceptive responding and pain ratings did not differ between postures suggesting no cardiopulmonary effects. This phasic modulation of the upper limb withdrawal response provides further support for arterial baroreceptor-mediated inhibition of nociceptive transmission.

When an adolescent has chronic pain many aspects of a parent's life can be affected, including their emotional and social functioning. The assessment of this multidimensional parental impact is an essential, yet often neglected, clinical task. This study reports on the development and psychometric evaluation of the Bath Adolescent Pain--Parental Impact Questionnaire (BAP-PIQ), an assessment tool comprising multiple scales thought to be relevant for better understanding changes in functioning and behavior associated with parenting an adolescent with chronic pain. ⋯ The BAP-PIQ may offer a comprehensive assessment of these impacts in both a research and a clinical setting. Further study of the validity of BAP-PIQ scales and their ability to detect clinically meaningful change would be of use. Additional data from samples comprising fathers of adolescents with chronic pain and parents of adolescents with non-musculoskeletal pain would be of benefit.

Given the high prevalence of depression in individuals with chronic pain and the negative outcomes associated with such comorbidity, the importance of assessing depressive symptoms is widely acknowledged by chronic pain specialists. The BDI-II is a commonly employed measure of depressive symptomatology at pain centres; however, little is known about its psychometric properties in this population. This study evaluated factorial validity, internal consistency, and gender invariance of the BDI-II in 481 patients with chronic pain. ⋯ Overall, results support the construct validity and internal consistency of the BDI-II for assessing depressive symptoms in both women and men with chronic pain. Results support the appropriateness of computing a total score and/or subscale scores. These results impact chronic pain researchers and clinicians, particularly given current trends toward empirically supported assessment.

The development and maintenance of chronic pain are influenced by its social context, and especially by the responses of family members. For children, very few instruments are available that measure pain-related parental behavior. Using the Multidimensional Pain Inventory for adults (MPI; [Kerns RD, Turk DC, Rudy TE. ⋯ Child-perceived maternal behavior was significantly related to overall parenting and to mothers' actual behavior as observed during a cold pressor test. Finally, the PPBI was sensitive to differences in mothers' responses depending on the specific nature of the child's pain. Child and parent reports of parental behaviors were modestly correlated and were differentially related to the validity measures, hence supporting the importance of assessing the social context of pediatric pain independently of both the child's and the parent's perspectives.
