Figures & data

Table 1 Sample Characteristics (N=167)

Characteristics	Mean ± SD or Number (%)
Age, years	70.04±6.2
Sex, male	73
Ethnicity, Han nationality	159
Housing status
Living alone	48
Living with spouse or grown children	119
Education^a
Low	41
Medium	98
High	28
PCSS (range, 16–80)	56.74±9.1
PEPPI (range,0–100)	78.38±18.6

Notes: ^aLow = none, primary school, lower-level vocational training, lower-level secondary general education; medium = middle-level vocational training, higher-level secondary general education; high = higher-level vocational training, academic education.

Abbreviations: PEPPI-10, Perceived Efficacy Patient-Physician Interactions Scale; PCSS, Patient’s Communication Perceived Self-efficacy Scale.

Table 2 Symmetry Measure of the Chinese Version PCSS

		Value	Asymptotic Standard Error ^a	Approximation T ^b
Coherence measure	Kappa	0.761	0.035	38.491
Effective cases	N	161

Notes: ^aNo assumption of zero. ^bAssuming zero hypothesis using asymptotic standard error.

Figure 2 Individual agreement between test and retest scores of the Chinese version PCSS. The horizontal solid line represents the mean difference between both scores. The dashed line represents the linear regression line through the data points. The outer dashed lines represent the 95% limits of agreement (mean difference±1.96 SD of the difference).
