The experience of embodiment in emerging adults with type 1 diabetes
Identity and bodily experiences in emerging adults with type 1 diabetes (T1D)
OBJECTIVE: Much remains unknown about how type 1 diabetes (T1D) affects one's identity and bodily experiences in emerging adults. Two relevant frameworks have been introduced in this respect, namely the illness identity (e.g. Oris et al.) and the experience of embodiment framework (e.g. Piran). Guided by these theoretical perspectives, this qualitative study explores identity and bodily experiences of emerging adults living with T1D. METHODS: A t…
Eating Disorder Symptomatology and Self-Concept in Late Childhood and Early Adolescence
The present study examined the longitudinal associations and directionality of effects between self-concept and eating disorder symptoms in late childhood and early adolescence. A total of 380 participants (Time 1: 52.2% female; M age = 9.97 years, SD = 0.84, range = 8–12 years) completed self-report questionnaires annually for 3 years. Cross-lagged panel models were used to examine the associations over time between global and domain-specific se…

Stability and change of illness identity in Belgian youth with type 1 diabetes
BACKGROUND: Youth with type 1 diabetes (T1D) are tasked with integrating their illness into their identity, a process conceptualized as illness identity. To date, longitudinal person-centered studies are lacking that substantiate qualitative research capturing illness identity as a process. PURPOSE: First, the current study examined patterns of stability and change among illness identity profiles in youth with T1D. Second, the study investigated …
Identity Matters for Well-Being
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 i…
Identity formation in adolescent and emerging adult cancer survivors
OBJECTIVE: Identity formation was investigated in adolescent and emerging adult cancer survivors from a (neo-)Eriksonian perspective by comparing survivors to control participants. In survivors, associations between identity and clinical/demographical variables and general and illness-specific functioning were investigated. DESIGN: : 19.54; 47% male) were matched on age and gender with healthy controls (2:1). MAIN OUTCOME MEASURES: All participan…
The Longitudinal Link Between Personality and Relationship Quality in Emerging Adults
Intimate relationships, both romantic relationships and friendships, are of special importance for identity development in emerging adulthood. In the current study, we investigated longitudinal associations between Big Five personality traits and relationship quality (romantic relationships and friendships) and whether these associations are mediated by identity. A sample of emerging adults ( N = 372, 55% women) completed self-report questionnair…
Trajectories of adaptive and disturbed identity dimensions in adolescence
To advance our understanding of adolescents' identity formation and how it may play into their psychological functioning, this study investigated developmental trajectory classes of adaptive and disturbed dimensions of identity formation, and whether adolescents belonging to different trajectory classes develop differently on self-esteem, resilience, symptoms of depression, and borderline personality disorder (BPD) features. Three-wave longitudin…
Impairment in personality functioning throughout adolescence and co-development with personality traits, emotion regulation strategies, and psychopathology
Personal identity, somatic symptoms, and symptom-related thoughts, feelings, and behaviors in adolescence
Identity Formation, Body Image, and Body-Related Symptoms
A person-centered perspective on the combined DSM-5 AMPD/ICD-11 personality model
Current results demonstrate the utility of a combined ICD-11/DSM-5 AMPD view from a person-centered perspective
Personal identity, somatic symptoms, and symptom-related thoughts, feelings, and behaviors
The present paper includes two studies examining how identity functioning is related to (psychological characteristics of) somatic symptoms. Study 1 examined associations between identity and somatic symptoms, whereas Study 2 additionally examined associations between identity and psychological characteristics of somatic symptoms and investigated the mediating role of anxiety and depressive symptoms in the association between identity disturbance…
Daily Identity Processes and Emotions in Young Adulthood
Identity trajectories and narratives during the transition out of undergraduate education among Georgian emerging adults
The transition out of university education and into the workforce represents a turning point in terms of the evolution of one's goals, roles, responsibilities, relationships, and lifestyle. For this reason, this transition might create important challenges and opportunities for identity formation. The present mixed-method longitudinal study examined identity formation processes in a sample of Georgian final-year undergraduate students over an 11-…
Identity synthesis and confusion in early to late adolescents
INTRODUCTION: Research on identity development has primarily studied over-time trends in identity status change and exploration and commitment processes among late adolescents and emerging adults. Identity development in early and mid-adolescents has generally been overlooked. Hence, little is known about how a sense of identity synthesis and confusion evolves from early to late adolescence for boys and girls. METHODS: The present cross-sectional…
Trauma and self‐harming behaviors in high school students
INTRODUCTION: This study investigated the link between trauma and self-harming behaviors in South African high school students, and examined the mediating role of identity formation. Traumatic experiences have been commonly associated with self-harming behaviors in adolescents. However, research addressing this association in non-Western countries is limited. METHODS: = 16 years) were included in the study. Students completed self-report question…
Nonsuicidal self-injury and identity formation in Indian clinical and nonclinical samples
Background: Nonsuicidal self-injury (NSSI) is being increasingly identified as an important emerging mental health issue in the West. Yet, NSSI has not been adequately studied in clinical and nonclinical contexts in countries like India. Aim: The aim of this study was to compare different features of NSSI between clinical and nonclinical samples in India. We also explored if the strength of the association between NSSI and disturbances in identit…
Internalization of Appearance Ideals and Appearance Comparison among Adolescent Boys and Girls
The detrimental impact of sociocultural pressures on adolescents’ body image has been widely established. However, it remains unclear why or for whom such pressures lead to increased appearance ideals internalization and appearance comparison. This cross-sectional study investigated moderating and indirect effects of identity confusion/synthesis in the relationship between (1) sociocultural pressures and (2) appearance ideals internalization and …
Co-Rumination and Depressive Symptoms in Adolescence
Non-suicidal self-injury and its association with identity formation in India and Belgium
The aim of the present study was to compare different features of Non-Suicidal Self-Injury (NSSI) in India and Belgium. We also explored whether the strength of the association between NSSI and disturbances in identity formation-a risk factor that can increase vulnerability to NSSI-was similar in young adults from India and Belgium. Data regarding NSSI and identity formation were collected from 182 young adults in India (56% females, mean age = 2…
Comorbidity Between Non-suicidal Self-Injury Disorder and Borderline Personality Disorder in Adolescents
In 2013, DSM-5 urged for further research on non-suicidal self-injury (NSSI) and defined NSSI disorder (NSSI-D) for the first time separate from borderline personality disorder (BPD). However, research on the comorbidity between NSSI-D and BPD symptoms is still scarce, especially in adolescent populations. The current study selected 347 adolescents who engaged at least once in NSSI (78.4% girls, M age = 15.05) and investigated prevalence, comorbi…
Handbook of Identity Theory and Research
Identity is one of the most extensively studied constructs in the social sciences. Yet, despite the wealth of findings across many disciplines, identity researchers remain divided over such enduring fundamental questions as: What exactly is identity, and how do identity processes function? Do people have a single identity or multiple identities? Is identity individually or collectively oriented? Personally or socially constructed? Stable or const…
Parenting and adolescent problem behavior
Parental monitoring, assessed as (perceived) parental knowledge of the child's behavior, has been established as a consistent predictor of problem behavior. However, recent research indicates that parental knowledge has more to do with adolescents' self-disclosure than with parents' active monitoring. Although these findings may suggest that parents exert little influence on adolescents' problem behavior, the authors argue that this conclusion is…
Capturing ruminative exploration
Conceptualizing parental autonomy support
In current research on parenting, 2 ways of conceptualizing perceived parental autonomy support can be distinguished. Parental autonomy support can be defined in terms of promotion of independence (PI) or in terms of promotion of volitional functioning (PVF). This study aimed to establish the empirical distinctiveness of both conceptualizations and to examine their relative contribution to the prediction of adolescents' adjustment. The authors co…
A developmental contextual perspective on identity construction in emerging adulthood
A developmental contextual test of a dual-cycle model of identity formation is presented. In addition to a commitment-formation cycle-represented by Marcia's (1966) classical dimensions of exploration in breadth and commitment making--the model comprises a commitment-evaluation cycle--constituted by 2 additional dimensions of exploration in depth and identification with commitment. In a sample of 402 college students assessed 4 times over 2 years…
Identity Formation in Early and Middle Adolescents From Various Ethnic Groups
Examining the Light and Dark Sides of Emerging Adults’ Identity
Short-term fluctuations in identity
The present study was aimed at examining one relatively neglected part of the identity formation process: the short-term dynamics of identity formation. The short-term dynamics were assessed by examining (a) the day-to-day course of 2 key dimensions of identity formation (i.e., commitment and reconsideration) and (b) the impact of fluctuations in commitment and reconsideration on subsequent levels of these 2 dimensions. Longitudinal data on 580 e…
Identity Statuses Based on 4 Rather Than 2 Identity Dimensions
Employment, Sense of Coherence, and Identity Formation
The present study investigated the influence of contextual (i.e., being in college vs. being employed) and psychological (i.e., sense of coherence) processes on achieving a sense of adulthood in a sample of 317 emerging adults. Identity formation, conceptualized as multiple dimensions of exploration and of commitment, was conceived of as a mediator of these relationships. Individuals who perceive themselves as adults scored higher on commitment a…
Personal Identity Processes from Adolescence Through the Late 20s
Personal identity formation constitutes a crucial developmental task during the teens and 20s. Using a recently developed five‐dimensional identity model, this cross‐sectional study (N = 5834) investigated age trends from ages 14 to 30 for different commitment and exploration processes. As expected, results indicated that, despite some fluctuations over time, commitment processes tended to increase in a linear fashion. Exploration in breadth and …
Converging identities
The present study was designed to ascertain the extent to which dimensions of acculturation would differ across personal identity statuses in a sample of 2,411 first- and second-generation, immigrant, college-attending emerging adults. Participants from 30 colleges and universities around the United States completed measures of personal identity processes, as well as of heritage and American cultural practices, values, and identifications. Cluste…
Identity processes and personality traits and types in adolescence
Personality traits are hypothesized to be among the most important factors contributing to individual differences in identity development. However, longitudinal studies linking Big Five personality traits to contemporary identity models (in which multiple exploration and commitment processes are distinguished) are largely lacking. To gain more insight in the directionality of effect and the developmental interdependence of the Big Five and identi…
Experiencing Loneliness in Adolescence
The present study builds on the child‐by‐environment model and examines the joint contribution of intra‐individual characteristics (i.e., self‐esteem and shyness) and peer experiences (i.e., social acceptance, victimization, friendship quantity, and friendship quality) in the association with loneliness. A total of 884 adolescents ( M age = 15.80; 68 percent female) participated in this multi‐informant study. Results indicated that, in addition t…
Personality traits, loneliness, and attitudes toward aloneness in adolescence
Within a dual-level model of personality, loneliness, and attitudes toward aloneness can be regarded as phase-specific adaptations that are influenced by personality traits. Therefore, we examined the associations between personality traits (i.e., the Big Five, sociotropy, and autonomy), loneliness, and attitudes toward aloneness in two samples of late adolescents ( N = 1388 and N = 419). A specific pattern of associations was found that replicat…
Developmental Typologies of Identity Formation and Adjustment in Female Emerging Adults
The developmental interplay between identity and adjustment was examined in a seven‐wave longitudinal study of 428 European female college students ( M age =18.8 years) over a period of 3 years, with semi‐annual measurement waves each year. Latent Class Growth Analysis (LCGA) was used to identify developmental typologies of both identity formation (i.e., dimensions of commitment and exploration) and adjustment (i.e., depressive symptoms and self‐…
The meaningful identity
Identity formation in adolescence is closely linked to searching for and acquiring meaning in one's life. To date little is known about the manner in which these 2 constructs may be related in this developmental stage. In order to shed more light on their longitudinal links, we conducted a 3-wave longitudinal study, investigating how identity processes and meaning in life dimensions are interconnected across time, testing the moderating effects o…
Personal identity processes and self-esteem
Characterizing the Self-System over Time in Adolescence
Linking identity and depressive symptoms across adolescence
This multisample longitudinal study examined the directionality of effects between identity exploration and commitment processes and depressive symptoms across adolescence. We compared two theoretical perspectives. According to the vulnerability model, identity uncertainty predicts depressive symptoms, whereas the scar model holds that depressive symptoms play into identity uncertainty. In investigating both models, we examined reciprocal within-…
The Interplay of Loneliness and Depressive Symptoms Across Adolescence

Why do the lonely stay lonely? Chronically lonely adolescents’ attributions and emotions in situations of social inclusion and exclusion
The goal of this study was to identify mechanisms associated with chronic loneliness by examining the effect of adolescents' accumulated history of loneliness on responses to new social situations. Specifically, this study investigated whether attributions and emotions in situations of social inclusion and exclusion differ between chronically lonely adolescents and adolescents with a different loneliness history. A total of 730 adolescents (Mage …
Identity exploration and commitment in early adolescence
Identity formation is a key developmental task in adolescence. Although many adolescents in modern societies face issues of identity, there are substantial individual differences in identity exploration and commitment. Little is known about the origins of these individual differences. The current study investigated the genetic and environmental contributions to identity formation. In total, 571 11-year-old twins (85 monozygotic complete pairs and…
Identity Processes and Coping Strategies in College Students
Identity Statuses Based on 4 Rather Than 2 Identity Dimensions
Unpacking commitment and exploration
A model of identity formation comprising four structural dimensions (Commitment Making, Identification with Commitment, Exploration in Depth, and Exploration in Breadth) was developed through confirmatory factor analysis. In a sample of 565 emerging adults, this model provided a better fit than did alternative two‐ and three‐dimensional models, thereby validating the unpacking of both exploration and commitment. Regression analyses indicated that…

Parental psychological control and dimensions of identity formation in emerging adulthood.
Longitudinal data were used to evaluate whether parental psychological control would have a negative impact on identity formation. Perceived psychological control and 4 identity dimensions (i.e., commitment making, exploration in breadth, identification with commitment, and exploration in depth) were assessed 5 times in a college sample. Associations between psychological control and identity (i.e., negative associations with both commitment dime…
Parenting, Identity Formation, and College Adjustment
Past research showed the importance of parenting towards adolescent identity formation, which, in turn, has been related to numerous indicators of adjustment. However, no study to date has tested an integrated mediation model that traces how parenting affects adjustment through processes of identity formation. The present study tested such a model using three-wave longitudinal data in a sample of college students and focused specifically on the d…
Conceptualizing parental autonomy support
In current research on parenting, 2 ways of conceptualizing perceived parental autonomy support can be distinguished.

This study aimed to establish the empirical distinctiveness of both conceptualizations and to examine their relative contribution to the prediction of adolescents' adjustment. The authors co…
Reciprocal Relations Between Teacher–Child Conflict and Aggressive Behavior in Kindergarten
In recent developmental theorizing, it has been hypothesized that teacher-child conflict and children's externalizing behavior affect one another reciprocally over time. However, the relation between teacher-child conflict and externalizing behavior has been mainly studied from a unidirectional point of view. Therefore, this study aimed to test the hypothesis of bidirectionality by means of a cross-lagged longitudinal design with kindergarten tea…
Identity Styles, Self-Reflective Cognition, and Identity Processes
The role that adaptive and maladaptive self-reflective cognitive processes play in identity formation was investigated. Results indicated that an informational identity style was positively associated with self-reflection and an awareness of internal states. A diffuse-avoidant identity style was linked negatively to internal state awareness, but positively to personal rumination. A normative identity style was positively associated with self-rumi…
Developmental Typologies of Identity Formation and Adjustment in Female Emerging Adults
The developmental interplay between identity and adjustment was examined in a seven‐wave longitudinal study of 428 European female college students ( M age =18.8 years) over a period of 3 years, with semi‐annual measurement waves each year. Latent Class Growth Analysis (LCGA) was used to identify developmental typologies of both identity formation (i.e., dimensions of commitment and exploration) and adjustment (i.e., depressive symptoms and self‐…
The Role Of Religion in Death Attitudes
Although it is widely assumed that religiosity plays an important role in individuals' attitudes about death, research to date has failed to reveal consistent associations between religiosity and death attitudes. Drawing from D. M. Wulff's (1991) multidimensional model of religiosity, the authors examined associations between religious attitudes as measured by the Post-Critical Belief Scale and death attitudes as assessed by the Death Attitude Pr…
Employment, Sense of Coherence, and Identity Formation
The present study investigated the influence of contextual (i.e., being in college vs. being employed) and psychological (i.e., sense of coherence) processes on achieving a sense of adulthood in a sample of 317 emerging adults. Identity formation, conceptualized as multiple dimensions of exploration and of commitment, was conceived of as a mediator of these relationships. Individuals who perceive themselves as adults scored higher on commitment a…
Capturing ruminative exploration
Identity Formation in Early and Middle Adolescents From Various Ethnic Groups
Basic need satisfaction and identity formation
The fulfillment of the basic psychological needs for autonomy, competence, and relatedness as postulated within self-determination theory was hypothesized to play an energizing role in identity formation, conceptualized as multiple dimensions of exploration and commitment. Two studies among high school and college students (N 714) were conducted to investigate (a) the cross-sectional relationships between need satisfaction and the identity dimens…
Motivational profiles from a self-determination perspective
The present research complements extant variable-centered research that focused on the dimensions of autonomous and controlled motivation through adoption of a person-centered approach for identifying motivational profiles. Both in high school students (Study 1) and college students (Study 2), a cluster analysis revealed 4 motivational profiles: a good quality motivation group (i.e., high autonomous, low controlled); a poor quality motivation gro…
“Are you afraid to die?” Religion and Death Attitudes in an Adolescent Sample
The purpose of this study was to provide an in-depth examination of the relationship between religion and death attitudes. First, we investigated whether the results found in previous research on adults could be generalized to adolescents. Second, we implemented a person-centered approach in studying this relationship. Questionnaires assessing death attitudes and religious attitudes were completed by 213 adolescents in a secularized country. Resu…
Longitudinal Associations Between Personality Profile Stability and Adjustment in College Students
In the present study, longitudinal associations of 3 aspects of personality profile stability (i.e., overall stability, distinctive stability, and within‐time normativeness) with 3 adjustment measures (i.e., depressive symptoms, self‐esteem, and delinquency) were examined, using 4 waves of longitudinal data on a Belgian college sample ( N =565). Longitudinal path models revealed strong longitudinal associations between adjustment and overall stab…

Why do Adolescents Gather Information or Stick to Parental Norms? Examining Autonomous and Controlled Motives Behind Adolescents’ Identity Style
Short-term fluctuations in identity
The present study was aimed at examining one relatively neglected part of the identity formation process: the short-term dynamics of identity formation. The short-term dynamics were assessed by examining (a) the day-to-day course of 2 key dimensions of identity formation (i.e., commitment and reconsideration) and (b) the impact of fluctuations in commitment and reconsideration on subsequent levels of these 2 dimensions. Longitudinal data on 580 e…
Life Satisfaction in Chronic Pain Patients
Chronic pain (CP) is a stressful condition that severely impacts individuals' lives. Researchers have begun to explore the role of religion for CP patients, but the literature is scarce, especially for West European populations. Drawing from the transactional theory of stress, this study examined the associations between the religious meaning system and the life satisfaction for a group of CP patients who were members of a Flemish patients' assoc…
Processes of Personal Identity Formation and Evaluation
Daily Dynamics of Personal Identity and Self–Concept Clarity
We examined the daily dynamics among self–concept clarity and identity processes, and their effects on distress, among a sample of 580 Dutch adolescents. Participants completed measures of identity, self–concept clarity, anxiety and depression at annual intervals; and daily single–item measures of self–concept clarity, identity commitments and reconsideration across three 5–day weeks. We examined (a) cross–lagged associations of self–concept clar…
