title: Psychological variables as predictors of the length of post-operative hospitalization.
abstract: The extent to which measures of anxiety and personality characteristics, which had been assessed preoperatively, could predict the length of hospital stay following surgery, above and beyond what could be predicted on the basis of biographical, medical-status and post-operative anxiety variables, was examined in 58 patients with gall-bladder disease. Hierarchical multiple regression analysis revealed that gender, previous operations, complications and State Anxiety (A-State) measured on the third day post-operatively, jointly explained a significant proportion of the variance in the length of hospitalization. Neither preoperative anxiety measures nor personality characteristics had any significant incremental value in the prediction.
