Capturing and addressing preschool children’s emotional and behavioural problems : Using parents’, teachers’ and children’s perspectives

Emotional and behavioural problems (EBP) are among the most common mental health problems in preschool children. EBP are also associated with poor parent mental health. Untreated, EBP can persist or worsen over time. In order to capture and address preschool children’s EBP, we need scientifically valid instruments that can access the perspectives of informants from different contexts of the child. We also need cut-off values for questionnaires assessing EBP that are representative of the population. Parenting support is a recommended intervention for addressing EBP in preschool children. Most parenting support programmes have a solid evidence-base and show positive effects on child EBP and parent wellbeing. However, we need a better understanding of the children’s emotional and relational experiences, especially in relation to their parents. Further, although the implementation of evidence-based interventions is a complex matter with substantial impact on intervention success, few studies assess the implementation process of parenting programmes. The studies constituting this thesis focused on preschool children. The Strengths and Difficulties Questionnaire (SDQ) was assessed for capturing EBP. Study I assessed the construct validity of the SDQ and its five subscales, when rated by fathers and preschool teachers. Confirmatory factor analysis was applied to evaluate construct validity. Results indicated that the SDQ can be used as an instrument to measure EBP in preschool children, rated by parents and preschool teachers. In study II, we established Swedish norms for the SDQ for preschool children. Results suggested lower SDQ cut-offs for Swedish preschool children compared with other countries, and higher cut-offs for boys compared with girls. In study III, preschool children whose parents participated in a parenting programme were interviewed regarding their emotional and relational experiences at home. Data were analysed using qualitative content analysis. The children provided accounts of negative and positive interactions with their parents, elaborately describing a coercive cycle with escalating conflicts and lack of problem resolution. In study IV, the implementation of the parenting programme Triple P in a preschool setting was assessed using the RE-AIM framework. Results indicated a successful implementation that relied on customisation of the programme; assessment of the process from parent, staff, and organisation levels; interdisciplinary collaboration; and continuous work on securing maintenance over time. This thesis provides pieces to a complex puzzle of understanding and addressing child mental health problems, particularly EBP. Assessing EBP from different perspectives and promoting children’s voices are essential, as well as actively working with the implementation of evidence-based programmes
