Abstract
Objective
Partners of cancer patients are the primary supporters and burdened at the same time. Support for partners is hitherto scarce and existing offers are rarely used. The PartnerCARE online intervention was specifically developed to address the caregiving partners’ needs. This two-arm parallel randomized controlled trial evaluates the feasibility, acceptability, and potential efficacy of PartnerCARE.
Methods
Sixty German-speaking partners of patients with various cancer entities were randomized into two conditions: intervention group with PartnerCARE (N=30) or waitlist-control group (N=30). Participants completed online questionnaires at baseline (T0), post-treatment (T1) and four-months follow-up (T2). Feasibility and acceptability outcomes included dropout rates, use and acceptance of PartnerCARE, individual user/e-coach feedback as well as negative effects. Relevant efficacy outcomes were assessed to test for potential intervention effects.
Results
Recruitment success illustrates demand for and acceptability of PartnerCARE. Satisfaction with the intervention was high (CSQ-I, T1: M=24.66, SD=6.42) and 73.3 % of participants completed the intervention. Study dropout rate was low (T1: 17%, T2: 29%). More positive than negative side effects of the intervention were identified, and negative ones were mainly related to ‘intrapersonal change’. For efficacy outcomes we found effects over time, with strongest effects within the intervention group from T0 to T1 in psychological distress (d=0.73, 95%-CI: [0.34; 1.12]) and anxiety (0.66, [0.26; 1.04]), but no group effects were significant at T1 and T2.
Conclusions
PartnerCARE is feasible, acceptable and potentially efficacious. Based on received feedback, PartnerCARE is currently undergoing further development and subsequently efficacy will be investigated in a randomized controlled trial.
