Description
Summary:Loneliness and isolation impact health detrimentally but are understudied in Parkinson's disease (PD). Outcome measurement properties for social connection remain unexplored in PD. To evaluate the measurement properties of six social connection outcomes in PD. We evaluated internal consistency, structural validity, and construct validity for measures of loneliness (brief UCLA Loneliness Scale [ULS3], short and long de Jong Gierveld Loneliness Scale [dJGLS], social isolation [Cohen Social Network Index-SNI total people, SNI high contact networks], and social support brief Perceived Social Support Scale [PSS]). We administered measures to 178 PD participants (M  = 67.9; 81.5% at Hoehn & Yahr stage 2). There was strong internal consistency, content validity across outcomes, and a 1-factor structure (PSS, ULS3) and a 2-factor structure (dJGLS) for two measures each. We provide a toolbox for clinicians and researchers studying social connection in PD.
