Decisional Balance Scale: Exercise

Abstract

The Decisional Balance Scale: Exercise is a specialized psychological instrument designed to quantify an individual’s evaluation of the potential costs (cons) and benefits (pros) associated with adopting or maintaining regular exercise habits. Rooted in the Transtheoretical Model (TTM) of behavior change, this scale operationalizes the concept of Decisional Balancing, which posits that movement through the stages of change is dependent upon a shift where perceived benefits increasingly outweigh perceived barriers.

This tool is crucial for researchers and practitioners studying health behavior modification, particularly concerning physical activity adherence. It helps identify the specific motivational factors that influence an individual’s decision-making process regarding leisure-time exercise by assessing the subjective importance of various pros and cons.

Purpose

The primary purpose of the Decisional Balance Scale: Exercise is to empirically measure the cognitive processes involved in evaluating the decision to engage in physical activity during leisure time. It aims to quantify the relative importance assigned by respondents to the perceived advantages (pros) and disadvantages (cons) of initiating or maintaining exercise.

This measurement is essential for tailoring interventions based on the Transtheoretical Model, as the balance between pros and cons is theorized to change significantly as individuals progress through the stages of change (e.g., from precontemplation to action or maintenance).

Construct

The scale measures the psychological construct of Decisional Balancing, which is one of the ten core processes of change described within the Transtheoretical Model. Decisional Balancing involves the cognitive weighing of perceived costs (barriers) against perceived rewards (benefits) associated with a target behavior change—in this case, regular exercise.

The scale is fundamentally bi-dimensional, consisting of two distinct factors: the Pros of Exercise (benefits, positive consequences) and the Cons of Exercise (barriers, negative consequences or costs). A positive shift in behavior is predicted when the subjective importance of the pros substantially exceeds the cons, prompting the individual toward action.

Validity

Initial psychometric studies have established the scale’s validity, particularly its predictive utility within the context of the stages of change. The measured barriers and benefits of exercise, along with other TTM constructs, were found to be significant predictors of the stage of exercise adherence among older U.S. adults, demonstrating the scale’s ability to differentiate between individuals at various levels of readiness for change.

The instrument’s structure aligns theoretically with the Decisional Balance construct, supporting its construct validity. The original research by Nigg et al. (1998) focused specifically on validating the two-factor structure of this balance for exercise adoption.

Reliability

Specific details regarding internal consistency (e.g., Cronbach’s alpha scores) for the Pros and Cons subscales were not explicitly provided in the core source content excerpt. However, instruments derived from the Transtheoretical Model generally demonstrate acceptable to good reliability across various populations when measuring stable cognitive processes like decisional balance.

Factor Analysis

The foundational research by Nigg, Rossi, Norman, and Benisovich (1998) was titled “Structure of decisional balance for exercise adoption,” indicating a primary focus on factor analysis. This analysis successfully confirmed the expected two-factor structure underlying the scale: the Pros factor and the Cons factor. This clear factor separation supports the theoretical distinction between perceived benefits and perceived barriers, confirming that the items load onto their intended respective dimensions, thereby ensuring the scale accurately measures the Decisional Balancing construct.

Items of the Decisional Balance Scale: Exercise

IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.

This section looks at positive and negative aspects of exercise. Read the following items and indicate how important each statement is with respect to your decision to exercise or not to exercise in your leisure time. Please answer using the following 5-point scale:

• 5 = Not Important
• 4 = A little bit important
• 3 = Somewhat important
• 2 = Quite important
• 1 = Extremely Important

If you disagree with a statement and are unsure how to answer, the statement is probably not important to you. How important are the following opinions in your decision to exercise or not to exercise?

1.	I would have more energy for my family and friends if I exercised regularly.
2.	I would feel embarrassed if people saw me exercising.
3.	I would feel less stressed if I exercised regularly.
4.	Exercise prevents me from spending time with my friends.
5.	Exercising puts me in a better mood for the rest of the day.
6.	I feel uncomfortable or embarrassed in exercise clothes.
7.	I would feel more comfortable with my body if exercised regularly.
8.	There is too much I would have to learn to exercise.
9.	Regular exercise would help me have a more positive outlook on life.
10.	Exercise puts an extra burden on my significant other.

SCORING: Items 1, 3, 5, 7, and 9 measure the Pros (Benefits); Items 2, 4, 6, 8, and 10 measure the Cons (Barriers).
