German-Language Version of the Compensatory Health Belief Scale : Assessing Its Psychometric Properties

2013, Radtke, Theda, Scholz, Urte, Keller, Roger, Perren, Sonja, Hornung, Rainer

This study constitutes the first psychometric examination of the German-language version of the Compensatory Health Belief (CHB) scale to assess the belief that unhealthy behavior can be compensated for by engaging in healthy behavior. Data from four different Swiss samples of 1,571 adolescents/students (age range 15 – 55 years), collected between 2007 and 2009, were used. Confirmatory factor analysis did not support either the hypothesized 4-factor structure or a second-order factor structure with a latent overall variable for the German-language CHB scale. These results support the inconsistent patterns of CHBs found across European cultures. Thus, the development of behavior-specific scales might be of advantage. Further recommendations for an improvement of the measurement of compensatory health beliefs are discussed.

Smoking is ok as long as I eat healthily : Compensatory Health Beliefs and their role for intentions and smoking within the Health Action Process Approach

2012-10, Radtke, Theda, Scholz, Urte, Keller, Roger, Hornung, Rainer

Compensatory Health Beliefs (CHBs) are defined as beliefs that the negative consequences of unhealthy behaviours can be compensated for by engaging in healthy behaviours. CHBs have not yet been investigated within a framework of a behaviour change model, nor have they been investigated in detail regarding smoking. Thus, the aim of this study was to investigate on a theoretical basis whether smoking-specific CHBs, as a cognitive construct, add especially to the prediction of intention formation but also to changes in smoking behaviour over and above predictors specified by the Health Action Process Approach (HAPA). The sample comprised 385 adolescent smokers (mean age: 17.80). All HAPA-specific variables and a smoking-specific CHB scale were assessed twice, 4 months apart. Data were analysed using structural equation modelling. Smoking-specific CHBs were significantly negatively related to the intention to stop smoking over and above HAPA-specific predictors. Overall, 39% of variance in the intention to quit smoking was explained. For the prediction of smoking, CHBs were not able to explain variance over and above planning and self-efficacy. Thus, smoking-specific CHBs seem mainly important in predicting intentions but not behaviour. Overall, the findings contribute to the understanding of the role of smoking-specific CHBs within a health-behaviour change model.

Smoking-specific compensatory health beliefs and the readiness to stop smoking in adolescents

2011-09, Radtke, Theda, Scholz, Urte, Keller, Roger, Knäuper, Bärbel, Hornung, Rainer

Objective: Compensatory health beliefs (CHBs) are defined as beliefs that negative consequences of unhealthy behaviours can be compensated for by engaging in other health behaviours. CHBs have not yet been investigated in detail regarding smoking. Smoking might cause cognitive dissonance in smokers, if they are aware that smoking is unhealthy and simultaneously hold the general goal of staying healthy. Hence, CHBs are proposed as one strategy for smokers to resolve such cognitive dissonance. The aim of the present study was to develop a scale to measure smoking-specific CHBs among adolescents and to test whether CHBs are related to a lower readiness to stop smoking. Design: For the main analyses, cross-sectional data were used. In order to investigate the retest-reliability follow-up data, 4 months later were included in the analysis. Method: A newly developed scale for smoking-specific CHBs in adolescents was tested for its validity and reliability as well as its predictive value for the readiness to stop smoking in a sample of 244 smokers (15–21 years) drawn from different schools. Multilevel modelling was applied.
Results: Evidence was found for the reliability and validity of the smoking-specific CHB scale. Smoking-specific CHBs were significantly negatively related to an individual's readiness to stop smoking, even after controlling for other predictors such as self-efficacy or conscientiousness. Conclusions: CHBs may provide one possible explanation for why adolescents fail to stop smoking.
