Infant and early childhood mental health Endorsement: Participant reports and perceptions. Infant Mental Health Journal, 1–17. https://doi.org/10.1002/imhj.70056https://hdl.handle.net/1805/52288There is agreement across infant and early childhood fields that infant and young children’s development depends on quality caregiving, which in turn requires a competent and well-supported workforce. This paper includes results of 3 qual- itative questions from an international survey (U.S. and Australia, n = 911) of holders of an Infant or Early Childhood Mental Health Endorsement credential that documents their knowledge and skills. The U.S.-based research team used a qualitative content analysis approach to code the responses. Benefits reported included increased knowledge of infant and early childhood mental health, recognition of expertise, and the opportunity to participate in a professional net- work. Participants also identified barriers to earning Endorsement, including time and money. Themes were analyzed with post hoc Chi Squares by participant demographic characteristics. Asian participants were more likely to report that Endorsement provided personal credibility and recognition and brought valid- ity to the field. American Indian participants were more likely to indicate that Endorsement validates the professional field. Participants from more established associations were more likely to report concerns about the costs of Endorsement. Results are discussed in the context of ongoing system changes that can increase diversity in leadership and the overall infant and early childhood workforce.eninfant mental healthearly childhood mental healthreflective supervision and consultationworkforce developmentArticle
