Perinatal depression poses substantial risks to both mothers and their offspring. Given its chronic and recurrent nature, developing effective prevention strategies is crucial. Internet-based cognitive–behavioural therapy (iCBT) has shown promise. However, the efficacy of specific CBT skills and the influence of individual differences remain unclear.
This protocol describes two harmonised multicentre, open-label, six-arm randomised controlled trials. Across both trials, a total of 2400 pregnant women between 10 and 20 weeks of gestation will be enrolled. After completing psychoeducation (PE), participants will be randomised to either the control condition (PE only) or one of five CBT programmes: behavioural activation (BA), assertion training, BA+cognitive restructuring, BA + problem solving or BA + behaviour therapy for insomnia. The objectives of the study are: (1) to ascertain that the iCBT approach is effective in perinatal depression, (2) to identify active CBT skills for perinatal women and (3) to examine interactions between these CBT skills and individuals’ baseline characteristics to find personalised and optimised therapy for individual women. The primary outcome is the point prevalence of depression at 1 month postpartum, defined as scoring of 9 or higher on the Edinburgh Postnatal Depression Scale.
The study has been approved by the Kyoto University Graduate School of Medicine Ethics Committee (C1710) and Nagoya City University Certified Review Board (2024A007). Anonymised study results will be presented at conferences and published by the investigators in peer-reviewed journals.

To examine clinical nurses' attitudes towards and self-reported experiences of family nursing in Japan following the relaxation of COVID-19 visitation restrictions. Particular attention is paid to early career nurses whose formative training occurred during visitation bans. The study focused on nurses' negative perceptions and emotional burdens associated with family involvement.
A quantitative-dominant mixed-methods cross-sectional study reported in accordance with the STROBE guideline.
Using a convenience sampling approach, a self-administered, paper-based questionnaire was distributed to clinical nurses in four general hospitals in Japan between January and May 2024. The questionnaire consisted of four parts: demographic and professional background, learning methods related to family nursing, 17 items including negatively valenced statements adapted from the Families' Importance in Nursing Care–Nurses' Attitudes (FINC-NA) scale, and one open-ended question. Quantitative data were analysed using descriptive statistics and t-tests, and qualitative responses were thematically analysed.
Of 1921 nurses invited, 957 responded (response rate: 49.8%), and data from 892 valid responses were analysed. Overall, the nurses demonstrated positive recognition of family nursing as a professional value but also reported lingering emotional burdens and practical challenges when interacting with families. Early-career nurses who began practice during the pandemic showed greater uncertainty and lower affective engagement. Thematic analysis revealed five key themes: relational disruption, emotional stress, moral conflict, reappraisal of family engagement and ongoing barriers.
The findings underscore the need to structurally and educationally reintegrate families into nursing care. Simulation-based training, clear institutional policies and hybrid communication models are essential to rebuild relational continuity and support nurses' emotional and ethical capacity for family nursing.
The findings highlight the need to structurally and educationally reintegrate families into clinical care to address the emotional burden and ambivalence reported by nurses. Organisational support—such as clear visitation policies, simulation-based education and reflective opportunities—can help rebuild nurses' relational competence and confidence in engaging with families. Creating supportive learning environments, including on-the-job mentoring and team-based reflection, may further facilitate the restoration of family nursing.
This study addressed how prolonged COVID-19 visitation restrictions disrupted family nursing practice in Japan, created generational differences in nurses' competencies, and shaped nurses' perceptions of family involvement. Nurses reported emotional strain, feelings of being monitored and lack of time when families were present. Early career nurses showed lower relational engagement, while experienced nurses expressed moral distress. ‘Latent indifference’ was also noted. The findings provide valuable insights for healthcare organisations, nurse educators and policymakers by informing strategies to reintegrate families into patient care, improve discharge planning and strengthen training models.

To clarify how public health nurses allocate their time across various tasks and compare time-use patterns between prefectural and municipal public health nurses in Japan, where distinct administrative mandates define their roles.
A self-reported, prospective time study.
Public health nurses from two municipalities and one prefecture recorded their daily practices and time allocations using Kintone. Time allocation differences by administrative level and job position were analysed using linear mixed-effects models.
Overall, 121 participants contributed 9502 person-days of data. Participants spent an average of 463.6 min/workday on work-related activities. Municipal public health nurses dedicated more time to application paperwork (64.0 min), health examinations (57.6 min), and individual coordination (48.3 min). Prefectural public health nurses allocated more time to business management and organisational operations (69.0 min) and traveliing, particularly in rural contexts. Managers spent less time on direct care and more on administrative tasks.
This study provides the first quantitative, self-reported evidence of task distribution among public health nurses across administrative levels and positions. The findings reflect structural differences in role expectations and underscore the need to reallocate workloads to better align with each level's mandate.
Task prioritisation, information and communication technology tool integration, and administrative support are essential in optimising public health nurses' contributions to community health. These strategies can reduce non-clinical workload and enable public health nurses to focus on high-impact, value-added public health services that promote health equity.
This study closes a longstanding gap by quantifying PHNs' time allocation, revealing the hidden burden of administrative work, and providing critical insights for workforce planning and sustainable public health service delivery.
This study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology guideline.

To assess the reliability and validity of a negative emotion scale for public health nurses conducting child abuse prevention activities.
A four-phase mixed method design.
Participants were public health nurses with experience in child abuse prevention across Japan. The initial scale was developed and refined based on previous studies, expert panel reviews, interviews with public health nurses, and a questionnaire-based pilot study. In 2024, 549 public health nurses completed a questionnaire on scale items. Item analysis, exploratory factor analysis, confirmatory factor analysis, comparisons with a preexisting scale, the number of times negative attitudes and the types of behaviours exhibited by parents were used to narrow the scale and assess its psychometric properties.
Item analysis and exploratory factor analysis reduced the scale to 15 items on two factors: ‘negative emotions toward aggressive and emotional attitudes’ and ‘negative emotions toward rejecting and uncooperative attitudes.’ Confirmatory factor analysis indicated a good model fit. The Cronbach's alpha was high, and the negative emotions scale score positively correlated with the pre-existing scale, negative attitudes and parental behaviours.
The Cronbach's alpha coefficient and other factors confirmed the scale's reliability, and correlations with other scales confirmed its validity.
Evaluating negative emotions provides critical insights into the quality of support and its influence on psychological well-being.
By assessing negative emotions that public health nurses find difficult using this scale, the support system for them can be examined.
STROBE checklist for cross-sectional studies was followed.
Public health nurses were involved in the generation of items for the scale. Their perspective was sought in determining the items for the scale.
