The present research aimed to determine if partners’ involvement in the rehabilitative care of people who have undergone an amputation predicted their wellbeing using a quantitative, cross-sectional design. Partners of people with an amputation were contacted through amputation-related advocacy groups and asked to complete an online questionnaire. Full data were collected from 66 participants who completed demographic information and measures of perceived social support, involvement in partner’s rehabilitative care, depression and posttraumatic growth. Predictors into the two regression models were chosen based on their zero-order correlations with the outcome variables. Only time since amputation and degree of prosthesis use were correlated with posttraumatic growth. Time since amputation, time in relationship and partner’s involvement in rehabilitative care were negatively correlated with depression. Both models (posttraumatic growth and depression) were significant. Involvement in partner’s care was an independent significant predictor for depression. More involvement in partners’ rehabilitative care was a significant predictor of less depression for partners of people with an amputation. The present research provides tentative evidence in support of the planned inclusion of partners by amputation rehabilitation services. Future research is needed to determine how robust this finding is.
