The sample included 366 adults with BDD who completed the BDD-YBOCS and other measures of BDD severity/impairment, psychiatric distress (i.e., anxiety and depression) and quality of life. Exploratory factor analysis supported two factors that were weakly correlated with each other (<em>r</em> = 0.21) (1) Severity (i.e., time, distress, interference, and avoidance; 31.6% of the variance): and (2) Resistance/Control (i.e., reduced effort to resist symptoms and lack of control over symptoms; 16.7% of the variance). The Severity factor had good internal consistency (<em>α</em> = 0.82) and good construct validity (<em>rs</em> = 0.69-0.81 with BDD severity/impairment; <em>rs</em> = 0.38-0.56 with depression and anxiety; and <em>rs</em> = 0.48-0.53 with functional impairment and quality of life).

The electronic databases PsycINFO, PubMed, Embase, Scopus, Medline, CINAHL, and Web of Science were searched. Fifteen papers met inclusion criteria and were appraised for quality using the QualSyst tool. There is very little literature exploring stigma in HD and quality of research is variable. Nevertheless, the literature suggests that a significant proportion of people who hoard and their families experience stigma, and HD is stigmatised by the public and associated with more rejecting attitudes and frustration amongst professionals. Finally, research exploring the impact of stigma on help-seeking in HD tentatively suggested a negative impact of stigma. Further research is needed to replicate and extend findings and address methodological limitations to provide an understanding of stigma on which approaches to enhance wellbeing and treatment uptake in HD can be developed.
