Key result
Inverted items in the Self-esteem and Mastery scales did not compromise their validity for predicting 8-year coronary heart disease risk, whereas positive items in the CES-D scale showed no significant relationship with CHD risk.
Why the study?
Do inverted items in the Self-esteem, Mastery, and CES-D scales represent a validity risk when the questionnaires are used in the context of coronary heart disease risk?

Do inverted items in the Self-esteem, Mastery, and CES-D scales represent a validity risk when the questionnaires are used in the context of coronary heart disease risk?
Inverted items in self-esteem and mastery scales do not compromise their validity for assessing coronary heart disease risk, supporting their use in behavioral cardiology, whereas positive items in the CES-D scale show low construct validity for biological outcomes.
Answers are grounded in this paper and cite their sources.
Inverted items remain valid in self-esteem and mastery scales for CHD risk; leaves open positive CES-D item utility in observational cohorts.
Psychological resources and risk factors influence risk of coronary heart disease. We evaluated whether inverted items in the Self-esteem, Mastery, and Center for Epidemiological Studies Depression scales compromise validity in the context of coronary heart disease. In a population-based sample, validity was investigated by calculating correlations with other scales ( n = 1004) and interleukin-6 ( n = 374), and by analyzing the relationship with 8-year coronary heart disease risk ( n = 1000). Negative items did not affect the validity of the resource scales. In contrast, positive items from Center for Epidemiological Studies Depression showed no significant relationships with biological variables. However, they had no major impact on the validity of the original scale.

Lundgren et al. (2018) conducted a cohort in Coronary heart disease risk (n=1,007). Inverted items in psychological scales (Self-esteem, Mastery, CES-D) vs. Original scales was evaluated on Validity of inverted items assessed via 8-year risk of first-time coronary heart disease event and correlation with IL-6. Inverted items in the Self-esteem and Mastery scales did not compromise their validity for predicting 8-year coronary heart disease risk, whereas positive items in the CES-D scale showed no significant relationship with CHD risk.
