Pilot Testing A Pregnancy Decision Making Tool for Women With Spinal Cord Injury (SCI)

The Decisional Conflict Scale is a self-report measure. Decisional conflict refers to a state of uncertainty about a course of action. For this study, this refers to uncertainty about pursuing a future pregnancy. The Values Clarity sub-scale refers to how much a respondent is clear about the values that guide their decision-making. Sub-scale items (3) are rated on 5-point Likert scales (ranging from strongly agree [5] to strongly disagree [1]) and summed for a total score range of 3 to 15. Higher scores represent greater clarity of values.

The Decisional Conflict Scale is a self-report measure. Decisional conflict refers to a state of uncertainty about a course of action. For this study, this refers to uncertainty about pursuing a future pregnancy. The Support for Decision Making sub-scale refers to how much support a respondent has from others about their decision-making. Sub-scale items (3) are rated on 5-point Likert scales (ranging from strongly agree [5] to strongly disagree [1]) and summed for a total score range of 3 to 15. Higher scores represent greater support for decision-making.

The Decisional Conflict Scale is a self-report measure. Decisional conflict refers to a state of uncertainty about a course of action. For this study, this refers to uncertainty about pursuing a future pregnancy. The Uncertainty about the decision sub-scale refers to how much a respondent is uncertain about the decision. Sub-scale items (3) are rated on 5-point Likert scales (ranging from strongly agree [5] to strongly disagree [1]) and summed for a total score range of 3 to 15. Higher scores represent greater certainty about the decision.

The Stage of Decision Making is a single item self-report measure. The options range from "haven't begun to think about choices" to "have already made a decision and unlikely to change my mind". The instructions were modified to refer to pregnancy and excluded the first two options of not having begun to think about choices given inclusion criteria. For this study, the scale ranged from 1 (are considering the decision now) to 4 (have already made a decision and am unlikely to change my mind). A higher score reflects greater readiness to make a decision.

Acceptability of decision making tool is refers to whether the intervention is agreeable or satisfactory. In this study we measured this by self-report. We used 13 items that measured the presentation of information of the tool rated on Likert scales ranging from 1 (poor) to 4 (excellent) which are summed across all items. Possible scores can range from 13 to 52, with higher scores reflecting better information presentation.

Demand refers to the likelihood of using an intervention after the study is over. For this study, it is a single item rated on Likert scales of 1 (definitely not likely) to 5 (very likely). Higher scores indicate a higher likelihood of using the tool after the study is over.

Ease of use refers to how easy an intervention is to use. In this study, we measures ease of use of the tool with a self-report, single item rated on Likert scales ranging from 1 (very hard) to 5 (very easy). A higher rating means the tool was considered easier to use.
