a ITT is based on a multiple imputation Markov chain Monte Carlo method with 10 iterations.
bAdjusted for baseline scores.
cSSCQ: Short Sense of Competence Questionnaire.
dThis variable was negatively skewed, and a cubic transformation was used.
eMSPSS: Multidimensional Scale of Perceived Support.
fSSL-12: Social Support List 12-Interactions.
gThis variable was skewed, but no transformation could better approach a normal distribution; therefore, raw data are presented.
hLS: Loneliness Scale.
iLSNS-6: Lubben Social Network Scale.
jPSS: Perceived Stress Scale.
kHADS: Hospital Anxiety and Depression Scale.
lPT: perseverance time.
mCarerQol: Care and Quality of Life scale.
nICECAP-O: Investigating Choice Experiments for the Preferences of Older People Capability measure for Older People.
