The study was conducted in accordance with the Declaration of Helsinki and related guidelines and regulations. The study was reviewed and approved by the Ethics Committee of Panzhihua Central Hospital, following the principles of informed consent and voluntary participation, and a cross-sectional survey was conducted from September to October 2022 in Panzhihua, Sichuan Province, China. Before the study was implemented, the investigators were informed of the significance of the study and signed an informed consent form, which clearly indicated that the survey would be completed anonymously, that their personal information would be protected, and that they had the right to choose whether or not to complete the questionnaire. All data were coded for research use only and only the research team had access to the data.
The study used the Demographic Characteristics Questionnaire (DQ), the Competence in Humanistic Care Inventory (CAI) and the Emotional Intelligence Inventory (WLEIS). The Demographic Characteristics Questionnaire was developed by the researcher to obtain information on socio-demographic variables such as age, gender, household registration, families with one child, level of education, time spent in clinical practice, experience in school clubs, experience in voluntary activities and whether they had received training in humanistic care.
The Competence Assessment for Human Caring ( CAI ) scale, developed by the American nurse scientist Nkongho, is used to test a person's ability to care for others [22]. The CAI has 37 items and is divided into three dimensions: awareness (14 items), which is the level of knowledge about caring; courage (13 items), which is the ability to take the initiative to care for oneself and others and to deal with unknown situations; and patience (10 items), which is patience and perseverance. "13 items were reverse scored. The total score of the CAI ranges from 37 to 259, with the cognitive dimension ranging from 14 to 98, the courage dimension from 13 to 91 and the patience dimension from 10 to 70. Higher total scores indicate greater caring capacity. The normative scores for this scale are: scores above 220.3 indicate high levels of caregiving; scores between 220.3 and 203.1 are moderate; scores below 203.1 indicate low levels of caregiving.
The English version of the WLEIS was developed by Wong and Law (2002) and has been translated and revised several times to form the Chinese version of the WLEIS, which consists of 16 items, including "Self-Emotional Appraisal", "Emotional Appraisal of Others", "Emotional Control", and "Emotional Appraisal of Others". "Each dimension contains 4 items and is scored on a 7-point Likert scale, where '1' means 'strongly disagree' and '7' means 'strongly agree'. The scores ranged from 16 to 112, with higher scores indicating higher emotional intelligence.
Data Source
The study was conducted among residents who were undergoing standardised training at Panzhihua Central Hospital. With 1,956 beds and nearly 2,000 staff, Panzhihua Central Hospital trains more than 300 residents each year and is the largest tertiary A general hospital in the Panzhihua region of western China.
The researcher created a standardised questionnaire with instructions on the Golden Data data collection platform and sent the questionnaire access QR code to the resident's WeChat group. Residents were not required to provide any personally identifiable information (name, ID, or contact information). During the survey, residents were informed about the purpose and significance of the study, and completion of the questionnaire was considered as the respondent's verbal consent to participate in the study.
Data analysis
Data were analysed using SPSS 26.0 statistical software, with differences considered statistically significant at P < 0.05. The study used descriptive statistics of residents' demographic characteristics, humanistic care competencies and emotional intelligence levels. Pearson correlation analysis was used to determine the relationship between humanistic care competencies and emotional intelligence scores. Multiple linear regression analysis was used to analyse the relationship between potential influences (i.e. socio-demographic characteristics, level of emotional intelligence) and the dependent variable, humanistic care competencies.
