Elaboration on Potential Outcomes Scale

What it measures

A compact, high-reliability instrument measuring individual differences in the tendency to mentally elaborate on the consequences of future actions. Nenkov, Inman & Hulland (2008) validated the EPO scale across five studies demonstrating that EPO+ and EPO- are distinct constructs with differential predictive validity: EPO+ predicts stronger approach motivation, more vivid positive mental imagery, greater responsiveness to gain-framed messaging, and higher aspirational goal adoption; EPO- predicts stronger avoidance motivation, heightened risk sensitivity, greater responsiveness to loss-framed and risk messaging, and more precautionary behaviour. Both dimensions are distinct from but related to regulatory focus (promotion/prevention focus) — EPO+ correlates with promotion focus orientation but also uniquely predicts elaboration depth for positive scenarios; EPO- correlates with prevention focus but additionally captures the cognitive elaboration tendency beyond mere orientation. The EPO scale is particularly valuable in health communication, financial decision-making, and advertising research where the effectiveness of outcome-focused messaging (benefit appeals vs. risk appeals) is moderated by individual elaboration tendencies. Validated on student and adult MTurk samples (n=167–324).

Scale items

Elaboration on Potential Positive Outcomes — EPO+ (4 items): tendency to mentally simulate and vividly think through positive consequences of a future choice. 7-point Likert (1=strongly disagree to 7=strongly agree). Items averaged.

• Before I make a decision, I like to think about the positive things that will result from my choice.
• When I consider a course of action, I imagine all the good things that will follow from my decision.
• Before making a decision, I like to envision the positive outcomes that could result.
• I think through all the positive things that could happen as a result of my choices.

Elaboration on Potential Negative Outcomes — EPO- (4 items): tendency to mentally simulate and vividly think through negative consequences and risks of a future choice. 7-point Likert. Items averaged.

• Before I make a decision, I think carefully about the negative things that could result from my choice.
• When I consider a course of action, I imagine all the bad things that could happen as a result.
• Before making a decision, I think through all the negative outcomes that might occur.
• I carefully think through all the ways a decision could turn out badly.

Usage notes & scoring

EPO+ and EPO- should always be reported and analysed as separate subscales — do not average into a combined EPO composite. The two dimensions show weak-to-moderate negative correlation (rapprox.-0.15 to -0.30); they are not bipolar endpoints of a single dimension. In framing studies, EPO+ moderates gain-frame effects and EPO- moderates loss-frame effects — test as distinct moderators. The EPO scale overlaps theoretically with regulatory focus (Higgins, 1997; RFQ id:497) but provides unique variance: EPO captures depth-of-elaboration tendency whereas regulatory focus captures orientation toward goals. When both are included, establish incremental validity. EPO- shows conceptual overlap with dispositional worry and anxiety — verify discriminant validity in health decision contexts. The scale has been used in nutrition label research, retirement savings communication, health screening adoption, and financial risk communication.
