The aim of this observational longitudinal cohort study was to describe relationships over time between degrees of stress of conscience, perceptions of conscience, burnout scores and assessments of person-centred climate and social support among healthcare personnel working in municipal care of older people. This study was performed among registered nurses and nurse assistants (n = 488). Data were collected on two occasions. Results show that perceiving one's conscience as a burden, having feelings of emotional exhaustion and depersonalization and noticing disturbing conflicts between co-workers were positively associated with stress of conscience. No significant changes were observed during the year under study, but degrees of stress of conscience and burnout scores were higher than in previous studies, suggesting that downsizing and increased workloads can negatively affect healthcare personnel. Following and expressing one's conscience in one's work, and perceiving social support from superiors are of importance in buffering the effects of stress of conscience.

The Perceptions of Conscience Questionnaire (PCQ) and the Stress of Conscience Questionnaire (SCQ) have previously been developed and validated within the 'Stress of Conscience Study'. The aim was to revalidate these two questionnaires, including two additional, theoretically and empirically significant items, on a sample of healthcare personnel working in direct contact with patients. The sample consisted of 503 healthcare personnel. To test variation and distribution among the answers, descriptive statistics, item analysis and principal component analysis (PCA) were used to examine the underlying factor structure of the questionnaires. Support for adding the new item to the PCQ was found. No support was found for adding the new item to the SCQ. Both questionnaires can be regarded as valid for Swedish settings but can be improved by rephrasing some of the PCQ items and by adding items about private life to the SCQ.

This study shows that associations between perceptions of conscience, stress of conscience and burnout are common experiences that are similar among HCP despite great differences in the characteristics of organisations. It can be burdensome for HCP to be unable to realise their ambitions to provide good care, and sex/gender can be an important factor to consider in the development of measures against the negative effects of stress of conscience. More studies are needed about how HCP's ambition to provide good care and sex/gender are related to perceptions of conscience, stress of conscience and burnout.

Interventions aiming to constructively address stress of conscience are rare. The aim of the study was to compare assessments of stress of conscience, perceptions of conscience, burnout, and social support among health care personnel (HCP) working in municipal residential care of older adults, before and after participation in a participatory action research (PAR) intervention aiming to learn to constructively deal with troubled conscience. Questionnaire data were collected at baseline and at follow-up (1-year interval; n = 29). Descriptive statistics and nonparametric statistical tests were used to make comparisons between baseline and follow-up. HCP gave significantly higher scores to the question, "Are your work achievements appreciated by your immediate superior?" at follow-up compared with baseline. No significant differences in levels of stress of conscience and burnout at follow-up were found. The results suggested that a PAR intervention aiming to learn HCP to deal with their troubled conscience in difficult situations could be partially successful.
