This was a cross-sectional, descriptive, and correlational study. The study was conducted between February and May 2021 with inpatients in the surgical clinics (brain and neurosurgery, general surgery, thoracic surgery, orthopedics and traumatology, urology) of a hospital with a 679-bed capacity and the pre-operative period for surgical procedures. Using G* Power 3.1.9.4 software to calculate the sample size, the number of people to be sampled was determined as 262 with 95% power and 5% type 1 error rate (23), but 300 people were included in the sample considering the data losses.
To determine the fear of surgery more objectively, the surgical interventions to be applied to patients with an equal number of minor and major surgeries from each surgery clinic were included (Table 1). The surgical classification was based on previous studies that considered various criteria such as blood loss, degree of pain and opening of a body cavity (e.g., abdomen, chest), need for monitoring, and length of hospital stay (24, 25).

Inclusion criteria for the study: (1) 18 years of age or older, (2) elective surgery is planned and is in the pre-operative process, (3) ASA I-III classified, and (4) can communicate in Turkish. Patients with a history of using drugs (antidepressant, antipsychotic, anxiolytic) affecting the central nervous system, a psychiatric disease, mental retardation, and did not want to participate in the study were excluded from the study.
Between the data collection dates, 330 patients were included in the study. However, the study was terminated with 300 patients because seven had used antipsychotic and antidepressant drugs, four refused to participate, and 19 had undergone emergency surgery (Fig. 1).
Data Collection And Tools
In this study data were collected using the patient information form and the Surgical Fear Questionnaire.
Patient Information Form; the researchers create questions to determine the patients' demographic data, the data about the surgery, and the emotional stress. Stress-related questions were formed by using the “The Brief Measure of Emotional Preoperative Stress Scale” (25). Pre-operative stress questions were asked in a yes/no format.
Surgical Fear Questionnaire (SFQ); this determines the level of fear of patients who will undergo elective surgery (26). A Turkish validity and reliability study was conducted in 2018 (27). The questionnaire, consisting of eight items, has an 11-Likert structure. Each item is scored as 0, “not afraid at all,” and 10, “very afraid.” The questionnaire has two sub-dimensions, each consisting of four items, showing the fear of surgery's short and long-term results. The subscale score is obtained by adding the scores of the four items in the sub-dimensions of the questionnaire, and the total score of the questionnaire is formed by adding the scores of the two subscales. The total questionnaire score is 0 at the lowest and 80 at the highest. A high score indicates a heightened fear of surgery. In this study, the mean score of the Surgical Fear Questionnaire was 18.04 ± 20.38, the mean score of the short-term sub-dimension (SFQ-S) was 9.49 ± 10.86, and the mean score of the long-term sub-dimension (SFQ-L) was 8.55. ±11.58. The Cronbach's a coefficient of the adapted scale was 0.93 (27). In our study, the Cronbach a coefficient of the scale was 0.88.
In data collection, patients were visited in the patient rooms of the clinic the day before the surgery, the purpose of the study was explained, and informed consent was obtained from the individuals who agreed to participate in the study. In the pre-operative period, the Patient Information Form and SFQ were applied to the patients. It took an average of 5–7 minutes for the patients to respond to the questionnaires.
Statistical Analysis
Data analysis was performed using the SPSS (Statistical Package for the Social Sciences) 24.0 program. The conformity of the data to the normal distribution was checked with kurtosis-skewness. To compare descriptive statistics and groups, independent samples t-test and ANOVA were used for normally distributed data, and Mann-Whitney U and Kruskal Wallis tests were used for data that did not conform to normal distribution. The relationship between scale total score and sub-dimension scores, age, number of previous surgeries, and pre-operative pain was evaluated by Spearman correlation analysis. The effect of items measuring the emotional stress of the patients on the fear scale total score was evaluated with multiple linear regression analysis. In all results, p < 0.05 was considered statistically significant.
