Predicting the onset of hazardous alcohol drinking in primary care: development and validation of a simple risk algorithm.

Background: Little is known about the risk of progressing to hazardous alcohol use in abstinent or low-risk drinkers.

Aim: To develop and validate a simple brief risk algorithm for the onset of hazardous alcohol drinking (HAD) over 12 months for use in primary care.

Design And Setting: Prospective cohort study in 32 health centres from six Spanish provinces, with evaluations at baseline, 6 months, and 12 months.

Predicting the onset of anxiety syndromes at 12 months in primary care attendees. The predictA-Spain study.

Background: There are no risk algorithms for the onset of anxiety syndromes at 12 months in primary care. We aimed to develop and validate internally a risk algorithm to predict the onset of anxiety syndromes at 12 months.

Methods: A prospective cohort study with evaluations at baseline, 6 and 12 months.

Psychometric properties of the List of Threatening Experiences--LTE and its association with psychosocial factors and mental disorders according to different scoring methods.

Background: The List of Threatening Experiences (LTE) questionnaire is frequently used to assess stressful events; however, studies of its psychometric properties are scarce. We examined the LTE's reliability, factorial structure, construct validity and explored the association between LTE scores and psychosocial variables and mental disorders.

Method: This study involved interviewing 5442 primary care attendees from Spain.

Psychosocial and sociodemographic predictors of attrition in a longitudinal study of major depression in primary care: the predictD-Spain study.

Background: Few data exist on the psychosocial factors associated with attrition in longitudinal surveys. This study was undertaken to determine psychosocial and sociodemographic predictors of attrition from a longitudinal study of the onset and persistence of episodes of major depression in primary care.

Methods: A systematic random sample of general practice attendees was recruited in seven Spanish provinces between October 2005 and February 2006.

Predicting the onset and persistence of episodes of depression in primary health care. The predictD-Spain study: methodology.

Background: The effects of putative risk factors on the onset and/or persistence of depression remain unclear. We aim to develop comprehensive models to predict the onset and persistence of episodes of depression in primary care. Here we explain the general methodology of the predictD-Spain study and evaluate the reliability of the questionnaires used.
