Parkinson's disease (PD) involves facial masking, which may impair social interaction. Older adult observers who viewed segments of videotaped interviews with individuals with PD expressed less interest in relationships with women with higher masking and judged them as less supportive. Masking did not affect ratings of men in these domains, possibly because higher masking violates gender norms for expressivity in women but not in men. Observers formed less accurate ratings of the social supportiveness and social strain of women than men, and higher masking decreased accuracy for ratings of strain. Results suggest that some of the problems with social relationships in PD may be due to inaccurate impressions and reduced desire to interact with individuals with higher masking, especially women.
KeywordsParkinson's disease; first impressions; social support; social strain; older adults Parkinson's disease (PD) affects 1.5 million individuals in the United States alone (National Parkinson Foundation, 2008), most of whom are older adults. PD is characterized by difficulties controlling movement including akinesia, tremor, and rigidity (Lang & Lozano, 1998), but may also include other problems such as cognitive impairment, depression, difficulty sleeping, and pain (Weintraub, Comella, & Horn, 2008a, 2008b, 2008c. Because the movement difficulties are not specific to gross motor movements, individuals with PD may also experience challenges controlling the musculature of the face and mouth, resulting in problems with communication. In fact, social relationships and communication problems are common complaints among individuals with PD (Schreurs, DeRidder, & Bensing, 2000), potentially affecting relationships with family, friends, and health care professionals. The aim of the current study was to examine the potential influence of facial masking on social interactions between older adults with PD and their age peers and how these effects may differ by observer and target sex. The study of relationships with peers is important because they may be fundamental to well-being (Pinquart & Sörenson, 2000), and because they are Publisher's Disclaimer: The following manuscript is the final accepted manuscript.

With increasing levels of facial masking, the face becomes rigid and fixed and spontaneous expression is impaired (Simons, Pasqualini, Reddy, & Wood, 2004;. This impairment can appear similar to the unresponsive face of dementia or the flat affect of depression (Schrag et al., 2007;Shulman, Taback, Rabinstein, & Weiner, 2002), posing challenges to suc...
