Readiness to Change Questionnaire

Abstract

The Readiness to Change Questionnaire (RCQ), developed by Rollnick, Heather, Gold, and Hall in 1992, is a brief, validated psychometric instrument designed to assess an individual’s stage of readiness to change a specific problematic behavior, primarily excessive drinking. It operationalizes the stages of change derived from the Transtheoretical Model (TMM). The RCQ is specifically intended for use in brief interventions or opportunistic clinical settings where rapid assessment of motivation is crucial for tailoring advice and increasing treatment efficacy.

Purpose

The primary purpose of the RCQ is to determine which of the three initial stages of change (Pre-contemplation, Contemplation, or Action) an individual occupies regarding a problematic behavior, initially focused on alcohol consumption. This assessment is vital because the effectiveness of clinical interventions, particularly those that are brief and opportunistic, is significantly enhanced when the intervention strategy is matched to the client’s current stage of readiness.

The scale was developed to be short and easily administered in clinical settings, such as primary care, where time is limited. By quickly identifying the level of motivation, clinicians can employ targeted techniques, such as those used in Motivational Interviewing, to encourage progress toward behavior modification rather than providing premature or irrelevant advice.

Construct

The RCQ measures the psychological construct of readiness to change, specifically as defined by the early stages of the Transtheoretical Model (TTM) proposed by Prochaska and DiClemente. The TTM posits that behavior change occurs in stages, and the RCQ captures three of these stages through its subscales: Pre-contemplation, Contemplation, and Action.

The Pre-contemplation stage is characterized by a lack of awareness or denial of the problem. Contemplation involves recognizing the problem and considering change, but without commitment. The Action stage involves actively implementing changes in behavior. The RCQ assigns scores across these dimensions to provide a profile of the respondent’s current motivational state regarding the targeted behavior.

Validity

Initial studies by Rollnick et al. (1992) demonstrated the RCQ’s construct validity by showing that the scale items loaded onto the hypothesized factors corresponding to the TTM stages. Furthermore, the instrument has shown predictive validity in various populations, where higher scores on the Contemplation and Action subscales often predict subsequent engagement in treatment or successful reduction in substance use.

The scale’s validity has been widely supported across numerous studies adapting it for different health behaviors (e.g., smoking cessation, diet). Its success lies in its ability to differentiate between individuals who are unaware of their problem and those who are actively working toward resolution, confirming its utility in clinical screening and research contexts.

Reliability

The RCQ exhibits acceptable to good internal consistency, as measured by Cronbach’s alpha for its three subscales based on the original standardization sample (Rollnick et al., 1992). The reported reliability coefficients are strong indicators of the consistency of the items within each factor:

• Pre-contemplation: Alpha = 0.82

• Contemplation: Alpha = 0.86

• Action: Alpha = 0.78

These values suggest that the items measuring each specific stage of change are highly correlated and reliably measure the intended construct. Subsequent research has generally confirmed these strong psychometric properties across diverse samples.

Factor Analysis

The original development of the RCQ utilized factor analysis to confirm its underlying structure, demonstrating that the 12 items reliably clustered into three distinct and theoretically meaningful factors corresponding to the stages of Pre-contemplation, Contemplation, and Action, aligning perfectly with the TTM framework.

Each factor is composed of four items. This three-factor structure has been consistently replicated in subsequent studies, confirming the instrument’s structural integrity and its utility as a measure of readiness specific to these three stages of the TTM.

Items of the Readiness to Change Questionnaire

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

1. I don’t think I drink too much.

2. I am trying to drink less than I used to.

3. I enjoy my drinking, but sometimes I drink too much.

4. Sometimes I think I should cut down on my drinking.

5. It’s a waste of time thinking about my drinking.

6. I have just recently changed my drinking habits

7. Anyone can talk about wanting to do something about drinking, but I am actually doing something about it.

8. I am at the stage where I should think about drinking less alcohol.

9. My drinking is a problem sometimes.

10. There is no need for me to think about changing my drinking.

11. I am actually changing my drinking habits right now.

12. Drinking less alcohol would be pointless for me.
