Model fit: χ² = 20.4 (df = 12, p = 0.06); CFI = 0.998; RMSEA = 0.025.
Alone = living alone; BMI = calculated body mass index; CES-D = Centers for Epidemiological Studies-Depression scale; Income = informant assessment of monthly income adequacy; MMSE = Mini-Mental State Exam; NpainRx = number of prescribed pain medications; PADL = self-reported pain-related functional limitations; Pd = depression-related pain report; PMD = self-reported pain-related doctor visits; PMED = self-reported pain-related medication use; Ps = somatic-related pain report; PSLP = self-reported pain-related sleep disturbance.
