“…Difficulties in decision‐making or decisional conflict was assessed by the Dutch version of the 16‐item Decisional Conflict Scale (DCS) developed by O'Connor16 and translated and validated by Koedoot et al 17. Cronbach's alpha for the DCS was 0.97.…”

ObjectiveTo evaluate preferences and decision‐making among high‐risk pregnant women offered a choice between Non‐Invasive Prenatal Testing (NIPT), invasive testing or no further testing.MethodsNationwide implementation study (TRIDENT) offering NIPT as contingent screening test for women at increased risk for fetal aneuploidy based on first‐trimester combined testing (>1:200) or medical history. A questionnaire was completed after counseling assessing knowledge, attitudes and participation following the Multidimensional Measure of Informed Choice.ResultsA total of 1091/1253 (87%) women completed the questionnaire. Of these, 1053 (96.5%) underwent NIPT, 37 (3.4%) invasive testing and 1 (0.1%) declined testing. 91.7% preferred NIPT because of test safety. Overall, 77.9% made an informed choice, 89.8% had sufficient knowledge and 90.5% had positive attitudes towards NIPT. Women with intermediate (odds ratio (OR) = 3.51[1.70–7.22], p < 0.001) or high educational level (OR = 4.36[2.22–8.54], p < 0.001) and women with adequate health literacy (OR = 2.60[1.36–4.95], p = 0.004) were more likely to make an informed choice. Informed choice was associated with less decisional conflict and less anxiety (p < 0.001). Intention to terminate the pregnancy for Down syndrome was higher among women undergoing invasive testing (86.5%) compared to those undergoing NIPT (58.4%) (p < 0.001).ConclusionsThe majority of women had sufficient knowledge and made an informed choice. Continuous attention for counseling is required, especially for low‐educated and less health‐literate women. © 2016 The Authors. Prenatal Diagnosis published by John Wiley & Sons, Ltd.

“…Decisional conflict was measured at T1/T2 with the Decisional Conflict Scale (DCS; including its subscales DM uncertainty, informed DM, values clarity, DM support, effective DM), validated for a Dutch population (Koedoot et al, 2001;O'Connor, 1995). The 16 items are measured on a 5-point Likert scale ranging from 0 (totally disagree) to 4 (totally agree).…”

Feasibility and effects of a decision aid about fertility preservation

This paper reports on the feasibility and preliminary effects of a decision aid (DA) about female fertility preservation (FP). We conducted a pilot multicentre randomized controlled trial of women with breast cancer aged 18-40 who were randomized to brochures or the DA. Over 18 months, 62 women were eligible, of which 42 were invited by their healthcare provider (74%) to participate in the study. A total of 36 women signed up for participation and 26 (72%) were randomized to brochures (n ¼ 13) or the DA (n ¼ 13). In both groups, many women (87%) read the brochures and eight women used all available brochures. In the intervention group, 7/13 women logged in to the DA. Women who received brochures had slightly less decisional conflict, whereas knowledge improved in both groups. Our results indicate that both brochures about FP and a detailed DA have beneficial effects with regard to knowledge, but the DA seemed to introduce slightly more decisional conflict (DC) than the brochures. Although we encountered challenges with recruitment, our design and measurements seem feasible and the effects of the information materials seem promising, hence justifying conducting a larger study.

“…The DCS has proven to be valid and reliable in different health-care decision-making contexts (O'Connor, 1995). The Dutch version of the DCS was translated, using a forwardbackward procedure, and was found to be reliable and valid (Koedoot et al, 2001). Decisional conflict ranges from 1 to 5.…”

Predictors of patients’ choices for breast-conserving therapy or mastectomy: a prospective study

et al. 2004

A study was undertaken to describe the treatment preferences and choices of patients with breast cancer, and to identify predictors of undergoing breast-conserving therapy (BCT) or mastectomy (MT). Consecutive patients with stage I/II breast cancer were eligible. Information about predictor variables, including socio-demographics, quality of life, patients' concerns, decision style, decisional conflict and perceived preference of the surgeon was collected at baseline, before decision making and surgery. Patients received standard information (n ¼ 88) or a decision aid (n ¼ 92) as a supplement to support decision making. A total of 180 patients participated in the study. In all, 72% decided to have BCT (n ¼ 123); 28% chose MT (n ¼ 49). Multivariate analysis showed that what patients perceived to be their surgeons' preference and the patients' concerns regarding breast loss and local tumour recurrence were the strongest predictors of treatment preference. Treatment preferences in itself were highly predictive of the treatment decision. The decision aid did not influence treatment choice. The results of this study demonstrate that patients' concerns and their perceptions of the treatment preferences of the physicians are important factors in patients' decision making. Adequate information and communication are essential to base treatment decisions on realistic concerns, and the treatment preferences of patients.
