Previous research examined the role of identity confusion and body dissatisfaction in eating disorder symptoms, but an integrative perspective including identity synthesis and positive body image is lacking. The current study used three-wave longitudinal data (T1: N = 403; 52.1% female; Mage = 14.85, SD = 0.89) spanning two years to examine the directionality of effects among identity, internalization of appearance ideals, body image, and eating ...

OBJECTIVE: Having Type 1 diabetes (T1D) may complicate the normative developmental task of personal identity formation in adolescence and emerging adulthood. Besides exploring and committing to identity choices in different life domains, youth with T1D need to integrate their illness into their identity, a process labeled as illness identity. The present study examined whether youth with T1D belonging to different personal identity trajectory ...

Adolescents' identity processes and their levels of well-being are likely to be intertwined. On the one hand, how adolescents cope with the core developmental task of forming their identity has important implications for their well-being. On the other hand, experiencing a condition of well-being can help adolescents consolidate their identity. This longitudinal study adopted a multidimensional and culturally sensitive perspective to unravel how ...

METHOD: Dutch-speaking emerging adults with CHD (N = 254, age range = 24-28 years) participated in a three-wave study, which is part of the I-DETACH 2 project. Cross-lagged analyses examined the ...

BACKGROUND: A comprehensive understanding of adult congenital heart disease outcomes must include psychological functioning. Our multisite study offered the opportunity to explore depression and anxiety symptoms within a global sample. OBJECTIVES: In this substudy of the APPROACH-IS (Assessment of Patterns of Patient-Reported Outcomes in Adults With Congenital Heart Disease-International Study), the authors we investigated the prevalence of ...

The premise of this study was to gain more insight into whether type 1 diabetes (T1D) can impact how youth perceive parents and peers. To address limitations of previous observational studies comparing youth with T1D to control youth, propensity weighting was used to mimic a randomized controlled trial. A total of 558 youth with T1D and 426 control youth (14-26y) completed questionnaires on parental responsiveness, psychological control, ...

BACKGROUND: With the introduction of non-suicidal self-injury disorder (NSSI-D) in DSM-5, the field obtained a standardised set of criteria to study those engaging in more severe and chronic NSSI. To date, no previous research has studied the development of NSSI-D longitudinally, leaving questions on its stability and potential prospective predictors unanswered. METHODS: 2162 community adolescents (M = 15.00 years, ...

OBJECTIVE: The long-term psychological effects of childhood cancer vary, with childhood cancer survivors reporting depressive symptoms, fear of cancer recurrence, and benefit finding. As cancer is considered a family disease, investigating the parental context may provide insight into such individual differences in psychological functioning of survivors. This study examined the directionality of effects among parental sense of incompetence, ...

As developmental and clinical research on identity has largely developed in disconnect, scholars recommend adopting a developmental psychopathology perspective on identity, which considers adaptive and pathological identity functioning. Such a perspective has also been introduced in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) Alternative Model for Personality Disorders (AMPD), which suggests that all personality ...
