The Efficacy of Decision Support E-book for Prostate Biopsy Decision Making
- Conditions
- Prostate-Specific Antigen
- Interventions
- Behavioral: Using an E-Book
- Registration Number
- NCT03881709
- Brief Summary
PURPOSE: This study is to test the efficacy of decision support E-Book for 1) increasing prostate biopsy knowledge and decision self-efficacy, and 2) reducing decisional conflict on prostate biopsy decision making in patients with elevated serum PSA.
DESIGN: The study is based on an experimental design. A convent sample of 110 adult males with a PSA greater than 4.0 ng/mL and the transrectal ultrasound-guided prostate biopsy suggested by a physician will be recruited from the urology clinics. Patients will be randomly assigned to the intervention and control group. The intervention group will receive the biopsy decision support intervention delivered by a nurse using an E-Book containing a comprehensive information about prostate biopsy. The control group will receive a health education about prostate biopsy. Data on biopsy knowledge, decision self-efficacy and decision conflict will be collected at pre and post test by using the study questionnaires.
ANALYSIS: Independent sample t -tests and chi-square tests will be used to compare the between group baseline equilibrium. Independent sample t -tests will be also used to analyze the between group differences in biopsy knowledge, decision self-efficacy, and decision conflict at post-test to evaluate the efficacy of the decision support intervention.
- Detailed Description
Prostate-specific antigen (PSA) is the primary screening test for prostate cancer. The elevated PSA test result is usually followed by the transrectal ultrasound-guided prostate biopsy (TRUS-Bx) for further diagnosis. However, patients often have lots concerns while deciding whether or not to undergo a prostate biopsy. They may worry about the biopsy associated complications such as urinary tract infection, pain, hematuria, bloody stools, etc., causing damage to urinary tract or sexual function, diagnosed with prostate cancer, or cancer spreading. Some may even worry about that a cancer cell can be transmitted to a partner through sexual activity after a biopsy. All these can cause physiological stress and decisional conflict for the patients. Therefore, it is necessary to provide decision support measures in order to improve the patients' knowledge regarding the advantages and disadvantages of prostate biopsy, to increase their decision self-efficacy, and to decrease their decisional conflict, thereby to achieve the share decision making goal. However, few studies have examined the efficacy of decision aids on prostate biopsy decision making. Therefore, the purpose of this study is to test the efficacy of decision support E-Book for 1) increasing prostate biopsy knowledge and decision self-efficacy, and 2) reducing decisional conflict on prostate biopsy decision making in patients with elevated serum PSA.
The study is based on an experimental design. A convent sample of 110 adult males with a PSA greater than 4.0 ng/mL and the transrectal ultrasound-guided prostate biopsy suggested by a physician will be recruited from the urology clinics. Patients will be randomly assigned to the intervention and control group. The intervention group will receive the biopsy decision support intervention delivered by a nurse using an E-Book containing a comprehensive information about prostate biopsy. The control group will receive a health education about prostate biopsy. Data on biopsy knowledge, decision self-efficacy and decision conflict will be collected at pre and post test by using the study questionnaires. The study instruments include the prostate biopsy knowledge scale, the Decision Self-Efficacy Scale, and the Decisional Conflict Scale. Data on whether the patients received a prostate biopsy will also be collected from the patients' medical records.
Independent sample t -tests and chi-square tests will be used to compare the between group baseline equilibrium. Independent sample t -tests will be also used to analyze the between group differences in biopsy knowledge, decision self-efficacy, and decision conflict at post-test to evaluate the efficacy of the decision support intervention.

- Primary Outcome Measures
Name Time Method Decisional Conflict Scale 1 hour after pre-test There are 16 items in the scale. Each item is rated on a 5-point Likert scale from 0(strongly agree) to 4(strongly disagree). The mean of 16 items multiplied by 25 represent the total score. The possible of the total score for the scale ranges from 0 \[no decisional conflict\] to 100 \[extremely high decisional conflict\]. Scores exceeding 37.5 are associated with decision delay.
Prostate Biopsy Knowledge Scale 1 hour after pre-test The scale measures patient's knowledge of prostate biopsy. There are 16 items in the scale. Each item is rated on dichotomy. The possible score for the scale ranges from 0 to 16. The higher values represent more knowledge of prostate biopsy patient have.
Decision Self-Efficacy Scale 1 hour after pre-test There are 11 items in the scale. Each item is rated on a 5-point Likert scale from 0(not confident) to 4(a lot confident). The mean of 11 items multiplied by 25 represent the total score. The possible of the total score for the scale ranges from 0 \[not confident\] to 100 \[extremely confident\].
