The study utilized family support and Amsterdam preoperative anxiety and information Scale (APAIS) questionnaires as instruments.

The results showed that almost all participant received high levels of family support (81.3%) and moderate level of preoperative anxiety (81.3%). The Spearman rank test indicated a significant relationship between family support and anxiety levels (p-value = 0.000 0.05) with a very strong, negative correlation (r = -.870). In conclusion, higher the family support is associated with lower anxiety level in preoperative patients. It is recommended that families provide consistent support during preoperative phase to help reduce patient level of anxiety.
