The role of stress in the onset of depressive disorders

2002

Background: We conducted the present study to evaluate the impact of stressful events on the onset of depressive disorders in a Spanish clinical sample, compared to a control group matched for age, sex, civil status and social class. We compared our results with those of other studies carried out with samples that were both clinically and culturally similar to ours. Method: Fifty depressed patients that were diagnosed with a depressive episode in the 6 months prior to the interview and 50 healthy controls were included in the study. Both groups were compared on the “Life Events and Difficulties Schedule” (LEDS). Results: Of the depressive patients, 68 % compared to only 18 % of the control …

[Genetic and environmental contributions to body mass index in a Spanish adolescent twin sample].

2015

Background and objective: Twin and family studies support large genetic influences on variability in body mass index (BMI), with heritability estimates ranging from 47% to over 90%. Our objective was to study the relative contributions of genetics and environment to BMI, evaluating sex differences, in an adolescent twin sample from Valencia, Spain. Material and methods: Five hundred eighty-four pairs of adolescent twins between 13 and 18 years of age completed the study (82 monozygotic [MZ] and 87 dizygotic [DZ] pairs of male twins, 118 MZ and 102 DZ pairs of female twins, and 195 opposite-sex pairs of DZ twins). To determine zygosity, teachers responded a questionnaire on physical similari…

Genetic and environmental contributions to perfectionism and its common factors

2015

Abstract The aims of this study: (1) To evaluate the relative contributions of genetics and environment to perfectionism and it's two constructs: self-oriented, and socially prescribed perfectionism. (2) To clarify genetic and environmental common origins of both personal and social components. Methods: Participants were 258 pairs of adolescent Spanish twins. Socially prescribed and self-oriented perfectionism were assessed using the perfectionism subscale of the Eating Disorder Inventory.

Rearing style and depressive disorder in adulthood: a controlled study in a Spanish clinical sample

1999

Objective: The aim of this study was to investigate the style of rearing in a sample of depressive patients and compare it with a control group of normal subjects of similar age, sex, and civil status. The hypothesis to verify was that among the depressives the style of rearing is characterised by a deficit in Emotional Warmth and an excess of Rejection and Protection. We analysed whether the severity of the depression – Major Depressive Disorders versus Depressive Disorders Not Otherwise Specified – was associated with differences in the perceived rearing conditions. Design: It was an observational study of the case/control type. There were 50 patients, whose first depressive episode (DSM-…

Dysfunctional rearing in community and clinic based populations with eating problems: prevalence and mediating role of psychiatric morbidity

2006

Objective To assess the presence of dysfunctional rearing in adolescent females with ED and the role of psychiatric comorbidity as mediating variable of this relationship. Method Administration of a rearing-attitude questionnaire (EMBU-A) and a standardized psychiatric evaluation. Data from a two-phase epidemiological study and from ED inpatients. Case diagnosis was performed using wide DSM-IV criteria (n = 29). Controls were matched by age and school. Results Significant differences were found between EDs subjects and controls on the scales of emotional warmth, overprotection, and rejection. There were no rearing differences between community cases and hospitalized patients. Paternal rejec…

Abstract Background . We investigate how the stress levels in a sample of patients with depressive disorders vary in the year prior to the onset of symptoms. Design . Observational study of the case/control type. Fifty patients whose first depressive episode began in the 6 months prior to the interview Method . The LEDS was applied to all the subjects. A calculation was made of the evolution week by week of stress throughout the year prior to the onset. Results . Notable differences were detected in the temporal profile of the stress between the depressive patients and control groups. The differences between them were especially far-reaching in the 26 weeks prior to the onset of the symptom…
