    Objectives: Because existing instruments for assessing surgical fear seem either too general or too limited, the Surgical Fear Questionnaire (SFQ) was developed. The aim of this study is to assess the validity and reliability of the SFQ. Methods: Based on existing literature and expert consultation the ten-item SFQ was composed. Data on the SFQ were obtained from 5 prospective studies (N = 3233) in inpatient or day surgery patients. These data were used for exploratory factor analysis (EFA), confirmatory factor analysis (CFA), reliability analysis and validity analysis. Results: EFA in Study 1 and 2 revealed a two-factor structure with one factor associated with fear of the short-term consequences of surgery (SFQ-s, item 1-4) and the other factor with fear of the long-term consequences of surgery (SFQ-l, item 5-10). However, in both studies two items of the SFQ-l had low factor loadings. Therefore in Study 3 and 4 the 2-factor structure was tested and confirmed by CFA in an eight-item version of the SFQ. Across all studies significant correlations of the SFQ with pain catastrophizing, state anxiety, and preoperative pain intensity indicated good convergent validity. Internal consistency (Cronbach's alpha) was between 0.765-0.920 (SFQ-total), 0.766-0.877 (SFQ-s), and 0.628-0.899 (SFQ-l). The SFQ proved to be sensitive to detect differences based on age, sex, education level, employment status and preoperative pain intensity. Discussion: The SFQ is a valid and reliable eight-item index of surgical fear consisting of two subscales: fear of the short-term consequences of surgery and fear of the long-term consequences.This study was conducted with departmental funding and supported by a grant from The Netherlands Organisation for Scientific Research (Zon-MW, http://www.zonmw.nl/en/), grant no. 110000007.

    Preoperative anxiety and catastrophizing : a systematic review of the association with chronic post surgical pain

    No full text
    OBJECTIVES: Anxiety and pain catastrophizing predict acute postoperative pain. However, it is not well established whether they also predict chronic postsurgical pain (CPSP). The aim of this systematic review and meta-analysis was to investigate whether high levels of preoperative anxiety or pain catastrophizing are associated with an increased risk of CPSP. METHODS: Electronic search databases included PubMed and PsychINFO. Additional literature was obtained by reference tracking and expert consultation. Studies from 1958 until October 2010, investigating the association between preoperative anxiety or pain catastrophizing and CPSP in adult surgery patients, were assessed. The primary outcome was the presence of pain at least 3 months postoperatively. RESULTS: Twenty-nine studies were included; 14 instruments were used to assess anxiety or pain catastrophizing. Sixteen studies (55%) reported a statistically significant association between anxiety or pain catastrophizing and CPSP. The proportion of studies reporting a statistically significant association was 67% for studies of musculoskeletal surgery and 36% for other types of surgery. There was no association with study quality, but larger studies were more likely to report a statistically significant relationship. The overall pooled odds ratio, on the basis of 15 studies, ranged from 1.55 (95% confidence interval, 1.10-2.20) to 2.10 (95% confidence interval, 1.49-2.95). Pain catastrophizing might be of higher predictive utility compared with general anxiety or more specific pain-related anxiety. DISCUSSION: There is evidence that anxiety and catastrophizing play a role in the development of CPSP. We recommend that anxiety measures should be incorporated in future studies investigating the prediction and transition from acute to chronic postoperative pain

    Prevalence and predictors of depression and well-being after hysterectomy: an observational study

    OBJECTIVES: To assess risk and predictive factors for depression and well-being, 3 and 12 months after elective hysterectomy. Secondary objectives were to assess the incidence of depression, level of well-being, and feelings of femininity. STUDY DESIGN: A prospective multicenter cohort study was performed among 419 women, undergoing hysterectomy for benign indication. Data were collected in the week prior to surgery, and in the per- and postoperative period up to the fourth postoperative day and 3 and 12 months after surgery. Sociodemographic variables, baseline health status, psychosocial predictors, and surgery data were assessed. Outcome measures were Center for Epidemiological Studies-Depression scale (CES-D, range 0-60), the 12-item well-being questionnaire energy and positive well-being subscales (range 0-12), and feelings of femininity. Predictor analyses were performed using linear mixed model analyses. RESULTS: Levels of depression, energy, and positive well-being after hysterectomy were predicted by their corresponding baseline levels (estimate 0.62 p<0.001, 0.39 p<0.001, 0.37 p<0.001, respectively) and baseline pain (0.31 p=0.003, -0.09 p=0.026, -0.10 p=0.008). Postoperative infection reported at 12 months affected CES-D and energy level. Several other gynaecological, psychosocial, or perioperative factors were also predictive for one of the outcomes. Prevalence of depression at baseline, 3 and 12 months was 24%, 19%, and 21%, respectively. In general, well-being scores were slightly higher 3 and 12 months after hysterectomy than at baseline. Feelings of femininity were not negatively affected in 92% of the patients. CONCLUSIONS: Preoperative psychosocial status, perioperative pain, and postoperative infection were found as predictors of psychological outcome after hysterectomy. In the majority of patients we observed small but significant improvements with regard to postoperative depression and well-being, while feelings of femininity were unaffected

    The Influence of Pre- and Postoperative Fear Avoidance Beliefs on Postoperative Pain and Disability in Patients with Lumbar Spinal Stenosis: Analysis of the Lumbar Spinal

    STUDY DESIGN: Prospective multi-center cohort study. OBJECTIVE: To evaluate the effect of pre- and postoperatively assessed fear avoidance beliefs (FAB) on pain and disability in patients with degenerative lumbar spinal stenosis (LSS) after decompression surgery. SUMMARY OF BACKGROUND DATA: To the present, the influence of pre- and postoperative FAB on the prognosis after surgery for LLS is still unclear. METHODS: Patients of the Swiss Lumbar Stenosis Outcome Study (LSOS) with confirmed LSS undergoing first-time decompression without fusion were enrolled in this study. The main outcome of this study was minimal clinically important difference (MCID) in SSM symptoms (pain) and function (disability) after twelve months. To analyze the influence of pre- and postoperatively assessed FAB on pain and disability we built simple and multiple logistic regression models. RESULTS: In this analysis of 234 patients undergoing decompression surgery for symptomatic degenerative LSS we found baseline FAB measured by the FAB physical activity subscale (FABQ-P) not to be associated with pain (OR 0.95; 95% CI: 0.55-1.67) and disability (OR 1.11; 95% CI: 0.64-1.92) at twelve months' follow-up. In the final multiple logistic regression models patients with high FABQ-P at six months (OR 0.46; 95% CI: 0.24-0.91) and high persistent FABQ-P at baseline and six months (OR 0.34, 95% CI: 0.16-0.73) were less likely to report a MCID for SSM symptoms at twelve months. Our analysis found a similar trend for disability, however, the results were not statistically significant. CONCLUSIONS: In elderly patients undergoing decompression surgery for symptomatic degenerative LSS preoperative fear avoidance beliefs were not a prognostic indicator for the outcome. Patients with FAB at six months and persistent FAB were less likely to experience clinically relevant improvement in pain at twelve months. Studies should address the importance of persistent postoperative FAB
