Attitudes, practices, and knowledge about bullying were evaluated in a sample of 274 primary care professionals, including general practitioners, pediatricians, community, pediatric and school nurses, and residents of these specialties. This study was based on a mixed method with a parallel convergent design without dominance between phases, data were collected concurrently, and conversion of the results from both phases was carried out during data interpretation. The quantitative phase had a cross-sectional observational design, using The Healthcare Provider’s Practices, Attitudes, Self-confidence, and Knowledge Regarding Bullying Questionnaire as an instrument. Descriptive and bivariate analyses were performed, which showed a positive correlation between higher self-confidence and knowledge scores and a greater predisposition to detect cases. However, although the dimensions of attitudes and knowledge yielded generally high data, low self-confidence was evident in addressing this problem. In addition, a lack of clear guidelines in the workplace was expressed, highlighting the need to create and provide specific resources to intervene in bullying in said context, which could develop an improvement in self-confidence, leading to greater well-being for the educational community regarding bullying.

How can we know the reality of the context of bullying in the field of primary health care? The aim of this study is to obtain a validated and reliable tool that allows measurement of the involvement of primary care professionals in addressing bullying through a systematic content validation process. A cross-cultural validation of the Healthcare Provider’s Practices, Attitudes, Self-Confidence, and Knowledge Regarding Bullying Questionnaire was conducted for the Spanish perspective. This involved linguistic adaptation through translation–back-translation, content validity index (CVI) analysis, construct validity using confirmatory factor analysis (CFA), and internal consistency (Cronbach’s α). The total CVI was 0.95, with individual item scores ≥ 0.78. CFA revealed a good fit for the three subscales, with discrimination indices (item–total correlation within the dimension) > 0.30. Cronbach’s α for each dimension indicated a high level of reliability, with values of 0.735 for attitudes, 0.940 for self-confidence, and 0.895 for knowledge. The questionnaire is valid and reliable for evaluating the knowledge, attitudes, and self-confidence of primary care professionals in Spain regarding bullying. Its validity and reliability guarantee its potential use in other health settings and may lead to better training of professionals and school biopsychosocial health.
