We explored positive and negative affect, quality of life (QOL), and associated factors in patients with pulmonary hypertension. We conducted this cross-sectional study using convenience sampling at a medical center in Taiwan. We used the Social Support Scale, positive and negative affect scale, and Short Form 36-item Health Survey to collect data. In these patients, greater social support was associated with less negative affect and better QOL (mental components). Lower Borg dyspnea scores or greater distances in the six-minute walk test were associated with more positive affect, less negative affect, and better QOL (both physical and mental components). Patients with less negative affect and more positive affect had better QOL (mental components). Therefore, nursing staff should routinely monitor the emotional status and QOL of patients with pulmonary hypertension, especially those with less social support and poorer cardiopulmonary function. Strengthening these aspects may improve patients' emotional status and QOL.
