Associations between childhood adversity, psychiatric symptoms, and self-esteem outcomes in adolescents and young adults: An experience sampling study KU Leuven
OBJECTIVES: Self-esteem and self-esteem stability are important factors during adolescence and young adulthood that can be negatively impacted by childhood adversity and psychiatric symptoms. We examined whether childhood adversity and psychiatric symptoms are associated with decreased global self-esteem as well as increased self-esteem instability as measured with experience sampling method. In addition, we examined if childhood adversity ...
Childhood Adversity and Emerging Psychotic Experiences: A Network Perspective KU Leuven
BACKGROUND AND HYPOTHESIS: Childhood adversity is associated with a myriad of psychiatric symptoms, including psychotic experiences (PEs), and with multiple psychological processes that may all mediate these associations. STUDY DESIGN: Using a network approach, the present study examined the complex interactions between childhood adversity, PEs, other psychiatric symptoms, and multiple psychological mediators (ie, activity-related and social ...
How to make mental health services more youth-friendly? A Delphi study involving young adults, parents and professionals KU Leuven
INTRODUCTION: Although youth-friendly service characteristics have been previously identified, consensus among a representative group of stakeholders about which of these characteristics are truly relevant to the youth-friendliness of services is currently lacking. In our study, young adults, parents and professionals were consulted on this topic to reveal existing (dis)agreement. In addition, (dis)agreement on feasibility for implementation in ...
Psychosis Endophenotypes: A Gene-Set-Specific Polygenic Risk Score Analysis KU Leuven
BACKGROUND AND HYPOTHESIS: Endophenotypes can help to bridge the gap between psychosis and its genetic predispositions, but their underlying mechanisms remain largely unknown. This study aims to identify biological mechanisms that are relevant to the endophenotypes for psychosis, by partitioning polygenic risk scores into specific gene sets and testing their associations with endophenotypes. STUDY DESIGN: We computed polygenic risk scores for ...
The role of threat anticipation in the development of psychopathology in adolescence: findings from the SIGMA Study KU Leuven
Childhood adversity is associated with psychopathology. First evidence in adults suggests that threat anticipation, i.e., an enhanced anticipation of unpleasant events creating an enduring sense of threat, may be a putative mechanism linking childhood adversity to psychopathology. This study aimed to test the indirect effect of childhood adversity on psychopathology via threat anticipation in a large community sample of adolescents. We measured ...
Lifetime and Current Self-Harm Thoughts and Behaviors and Their Relationship to Parent and Peer Attachment KU Leuven
Background: Previous research suggests attachment is a vulnerability factor for self-harm thoughts and behaviors in adults. Yet, few studies have investigated this relationship during adolescence, although adolescence is a critical period for changes in attachment relationships and self-harm onset. Whether and how attachment relates to self-harm thoughts and behaviors as measured in daily life is also unknown. Aims: To investigate whether and ...
The role of identity in the development of depressive, anxiety, and psychosis symptoms in adolescents exposed to childhood adversity KU Leuven
INTRODUCTION: Childhood adversity is a major risk factor for psychiatric disorders and has especially been associated with an admixture of depressive, anxiety, and psychosis symptoms. Identity formation, a main developmental task during adolescence, may be impacted by these adverse experiences and act as an important process in the association between childhood adversity and psychopathology. METHODS: We investigated the association between ...
Ecological and Convergent Validity of Experimentally and Dynamically Assessed Capacity for Social Contingency Detection Using the Perceptual Crossing Experiment in Adolescence KU Leuven
The Perceptual Crossing Experiment (PCE) captures the capacity for social contingency detection using real-time social interaction dynamics but has not been externally validated. We tested ecological and convergent validity of the PCE in a sample of 208 adolescents from the general population, aged 11 to 19 years. We expected associations between PCE performance and (a) quantity and quality of social interaction in daily life, using Experience ...
