Previous studies have found a relationship between job-related stress and depressive symptoms in different occupational groups, and that personality may modify the risk of developing depressive symptoms. We aimed to examine the association of personality and other individual and work conditions with depressive symptoms.
A sample of 498 teachers answered a questionnaire concerning individual and work characteristics, some job-related perceptions, and the wish to change jobs. Depressive symptoms were measured by the Center for Epidemiologic Studies Depression scale (CES-D) and personality was measured by the Temperament and Character Inventory (TCI-125).
Depressive symptoms were associated with female gender, age, low job satisfaction, high job stress, the wish to change jobs, working at a public school, and with higher scores on harm avoidance and novelty seeking and lower scores on self-directedness.
Our results underline the influence of personality traits on the development of depressive symptoms independently of other individual characteristics and the occupational context.
The main aim of this study was to explore whether specific groups of patients with first episode non-affective psychosis could be identified on a psychopathological basis and, then, whether such identified groups could be validated by exploring their correlation with a variety of neurodevelopmental markers.
Eighty-seven patients with a first episode of non-affective psychotic disorder were consecutively recruited. We assessed psychopathology and neurological soft signs using the PANSS and the Neurological Evaluation Scale, respectively. We collected information on obstetric complications, premorbid adjustment and family history.
All PANSS symptoms were analysed using principal component analysis and four factors were obtained (negative, disorganization, positive and paranoid). Subsequently, the four factors were subjected to a cluster analysis where three groups emerged: “paranoid” (n = 40), “low score” (n = 29) and “negative” (n = 18) subtype. After adjusting by sex and age, we found that the “negative group” had poorer social premorbid adjustment, worse verbal fluency and higher prevalence of both obstetric complications and neurological soft signs, when compared with the “low score” group. Similarly, the “negative group” showed significantly poorer social premorbid adjustment and higher number of neurological soft signs than the “paranoid group”.
Our results support that, among non-affective first onset psychotic patients, those with predominant negative symptoms are more likely to correlate with higher presence of neurodevelopmental markers.
Estudios anteriores han encontrado una relación entre el estrés relacionado con el trabajo y los síntomas depresivos en grupos ocupacionales diferentes, y han hallado que la personalidad puede modificar el riesgo de desarrollar síntomas depresivos. Nosotros pretendimos examinar la asociación de la personalidad y otras condiciones individuales y laborales con los síntomas depresivos.
Sujetos y método.
Una muestra de 498 profesores respondió a un cuestionario acerca de características individuales y laborales, algunas percepciones relacionadas con el trabajo y el deseo de cambiar de empleo. Los síntomas depresivos se midieron por la Escala de Depresión del Centra para Estudios Epidemiológicos (CES-D) y la personalidad se midió por el Inventario del Temperamento y el Carácter( TCI-125).
Los síntomas depresivos se asociaban con el género femenino, la edad, la satisfactión laboral baja, el estrés laboral alto, el deseo de cambiar de empleo, trabajar en una escuela pública, y con puntuaciones más altas en evitación del daño y búsqueda de novedad y puntuaciones más bajas en autodirección.
Nuestros resultados subrayan la influencia de los rasgos de personalidad en el desarrollo de los síntomas depresivos con independencia de otras características individuales y el contexto ocupacional.
Smoking may have a beneficial effect on either schizophrenic symptoms or antipsychotic side-effects, but studies are hampered by the lack of control of confounding factors.
To explore the self-medication hypothesis in a large sample of stable out-patients with schizophrenia.
Symptoms, assessed with the Positive and Negative Syndrome Scale (PANSS), and number of hospitalisations were compared in 250 out-patients with DSM–IV schizophrenia classified into three categories: highly dependent smokers, mildly dependent smokers and non-smokers. Log-linear analysis was used to control for potential confounding and interacting variables.
High PANSS total scores and positive symptoms were less frequent in mildly dependent smokers than in non-smokers or highly dependent smokers. The highly dependent smokers had the worst outcome.
The data do not generally support the self-medication hypothesis but rather suggest a complex interaction between nicotine dependence and schizophrenic symptoms.
