Perceived autonomy determines helpfulness of social support in patients with implantable cardioverter defibrillators

Abstract

Self-Determination theory of Ryan & Deci (2000) suggests that perceived autonomy support plays an important role for the quality of life (QoL) in patients with implantable cardioverter defibrillators (ICD). Of N=113 ICD-patients (M=63 years, SD=12.34, 76% men) data on QoL (SF-36), overprotective social support (PFUK), perceived autonomy support (RNSS), depression (PHQ-9) and self-efficacy (FERUS-26) was collected. In a multiple regression (F(6,106)=57.339, p<0.001, R2=.764) mental QoL is significantly predicted by perceived autonomy support (β=0.145, p=0.06), while actually received overprotective support has no impact (β=0.005, p=0.981). These results persist under control of socio-demographic (age, sex), medical (BMI, LVEF) and other psychometric variables (depression, self-efficacy). These results link to previous findings showing that it is particularly important how patients perceive their social support independent of the support they actually receive. Relatives and cardiologist of the patient should support the patient’s autonomy but also get feedback whether it is well-received by the patient to optimize ICD-patient care and QoL.
