The complex story of educational identity in adolescence: Longitudinal relations with academic achievement and perfectionism.

Objective: Education has a strong impact on adolescent development. This study investigated the complex longitudinal associations between educational identity processes, academic achievement, and perfectionism.

Method: The study used a 4-wave design (N = 744 adolescents, M = 15.

The Very Best of Me: Longitudinal Associations of Perfectionism and Identity Processes in Adolescence.

Personality and identity formation are intricately linked in adolescent development. The personality disposition of perfectionism has been associated with identity processes, but their longitudinal interplay in adolescence has not yet been investigated. This four-wave study, with 5- to 6-month intervals between each wave (N = 744 Caucasian adolescents, M  = 15.

Eating disorder symptoms and the 2 × 2 model of perfectionism: mixed perfectionism is the most maladaptive combination.

Purpose: The 2 × 2 model of perfectionism (Gaudreau and Thompson in Personal Individ Diff 48:532-537, 2010) represents an important addition to the perfectionism literature, but so far has not been studied in relation with disordered eating.

Method: Using the 2 × 2 model as analytic framework, this study examined responses from a convenience sample of 716 participants aged 19-68 years (71% female) investigating how self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) predicted individual differences in eating disorder symptoms, additionally controlling for body mass index, gender, and age.

Results: Results showed a significant SOP × SPP interaction indicating that the combination of high SOP and high SPP-called "mixed perfectionism"-was associated with the highest levels of eating disorder symptoms.

Perfectionistic concerns predict increases in adolescents' anxiety symptoms: a three-wave longitudinal study.

Background And Objectives: Although perfectionism has been proposed to be a risk factor for the development of anxiety, research on perfectionism and anxiety symptoms in adolescents is scarce and inconclusive. The aim of the present study was to investigate whether the two higher-order dimensions of perfectionism - perfectionistic strivings and perfectionistic concerns - predict the development and maintenance of anxiety symptoms. An additional aim of the present study was to examine potential reciprocal effects of anxiety symptoms predicting increases in perfectionism.

Perfectionism and eating disorder symptoms in female university students: the central role of perfectionistic self-presentation.

Purpose: Numerous studies have found perfectionism to show positive relations with eating disorder symptoms, but so far no study has examined whether perfectionistic self-presentation can explain these relations or whether the relations are the same for different eating disorder symptom groups.

Methods: A sample of 393 female university students completed self-report measures of perfectionism (self-oriented perfectionism, socially prescribed perfectionism), perfectionistic self-presentation (perfectionistic self-promotion, nondisplay of imperfection, nondisclosure of imperfection), and three eating disorder symptom groups (dieting, bulimia, oral control). In addition, students reported their weight and height so that their body mass index (BMI) could be computed.

On the Development of Perfectionism: The Longitudinal Role of Academic Achievement and Academic Efficacy.

Objective: Although perfectionism is a prominent personality disposition, only a few longitudinal studies have investigated how perfectionism develops. Theoretical models and qualitative studies have posited that academic success is a developmental antecedent of perfectionism. Yet, quantitative studies tend to interpret the cross-sectional relationships as academic success being an outcome of perfectionism.
