The associations between family strain, depression, and chronic pain interference vary across individuals, suggesting moderated relations, and one possible moderator is somatic amplification. The current study examined a moderated mediation model that investigated (a) whether depression mediated the relation between non-spouse family strain and chronic pain interference and (b) whether somatic amplification moderated the association between depression and chronic pain interference. ⋯ The presence of chronic pain has been associated with family dynamics changing, which may be linked with higher levels of non-spouse family strain. A negative family environment may be related to the development of depression, which may be associated with the severity and inability to cope with chronic pain. Somatic amplification may strengthen the association between depression and pain intensity.
