Show moreThe overarching goal of this dissertation was to investigate parenting processes in relation to affective well-being in families in the daily flow of life from different perspectives (i.e., adolescent, mother, father), on different levels (i.e., objective, momentary, and daily), and in a clinical sample (families with an adolescent with a depression) in addition to community samples. Our findings underline the importance of daily parental warmth and criticism of mothers and fathers for adolescents’ well-being. In addition, we showed that adolescents, parents, and their perceptions of parenting influence each other and that becoming more attuned to each other’s intention and needs is essential. Importantly, we consistently demonstrated that not only the extent and direction of the dynamic processes between parenting and affect in daily life differs between, but also within persons and families. This stresses the need for research focusing on individual processes and combining quantitative with qualitative measures. The use of more idiographic approaches would not only enable gaining more insight into these differences between individuals, but also contribute to identifying parenting practices that work for almost all adolescents. This would facilitate the development of interventions combining universal parenting principles with suggestions for tailoring it to individual- or family-specific situations. Show less

Show moreThis thesis aimed to lay the foundation for a new set of Dutch mental health instruments to measure depression and anxiety in an efficient, reliable, valid, and responsive manner. More specifically, the Dutch-Flemish PROMIS adult v1.0 item banks for Depression and Anxiety were psychometrically evaluated for computerized adaptive test (CAT) administration in the Dutch clinical and general population. CAT is a modern methodology that can be used to develop instruments that measure both efficiently and reliably as only the most appropriate questions are administered, and assessment terminates as soon as sufficient reliability is achieved. For the PROMIS CAT instruments, this was demonstrated in the thesis: measuring depression and anxiety in Dutch persons was highly efficient and reliable. Moreover, the CAT instruments were shown to measure depression and anxiety sufficiently responsive and valid as well. This even includes longitudinal validity, which has barely been studied for other Dutch mental health instruments. Overall, it was concluded that the new instruments are an improvement over available instruments. Therefore, using the PROMIS CAT instruments in clinical practice may lead to more efficient and reliable measurement that supports professionals and patients in evaluating patients' treatment.

Show moreThis dissertation describes the findings of six studies on mental health problems in the family context, specifically focusing on the associations with the parent-child relationship, parenting behaviors and experiences of childhood maltreatment. The aim is to better understand the risk factors, development and transmission of common psychological problems in order to contribute to prevention and treatment strategies for common psychological problems such as anxiety and depression.Overall, the findings underline the importance of the family context in the development and levels of mental health problems. In addition to the impact of one's own negative parenting experiences, including lack of warmth and experiences of emotional or physical abuse, negative parenting experiences of one's siblings are also associated with elevated anxiety and depressive symptom levels.We also found that externalizing problems of fathers and children have a negative impact on the parent-child interactions. In addition, we found that children with behavioral problems during early adolescence experience harsher parental discipline, even three years later.In the current treatment guidelines for common mental disorders, most therapies focus on the individual. An (additional) systemic approach and considering past and present family relationships in therapy, can be of additional value. For example, supporting families with interventions to improve the parent-child relationship can be helpful in the short and long term. Moreover, (early) treatment of psychological and behavioral problems of the parent or child might be beneficial for all family members. Show less
