Objective: The vividness of imagining emotional feelings in positive situations (EFP) in non-clinically dysphoric and non-dysphoric individuals and its relation to dysphoric and positive feelings was examined.
Method: Participants were university students in Study 1 (N = 106, 84 women; 18-45 years), in Study 2 (N = 43, 39 women; 20-47 years), in Study 3 (N = 109, 92 women; 18-50 years) who filled out a set of questionnaires assessing depressive symptoms, cognition measures, and then completed an affective imagery task, using a cross-sectional design.
Results: Non-clinically dysphoric participants imagined less vividly EFP than non-dysphoric participants.
Objectives: To investigate whether an authorship effect is found that leads to better performance in studies conducted by the original developers of the Patient Health Questionnaire (PHQ-9) (allegiant studies).
Design: Systematic review with random effects bivariate diagnostic meta-analysis. Search strategies included electronic databases, examination of reference lists and forward citation searches.
Background: There is interest in the use of very brief instruments to identify depression because of the advantages they offer in busy clinical settings. The PHQ-2, consisting of two questions relating to core symptoms of depression (low mood and loss of interest or pleasure), is one such instrument.
Method: A systematic review was conducted to identify studies that had assessed the diagnostic performance of the PHQ-2 to detect major depression.
Background: Depression in older adults is often under recognised despite it being the most common mental health illness in this age group. An increasing older adult population highlights the need for improved diagnostic rates. Brief versions (15 items or less) of the Geriatric Depression Scale (GDS), which are suitable for busy clinical practice, could improve detection rates.

Methods: A systematic review of the literature was conducted to identify studies that validated the GAD-7 or GAD-2 against a recognized gold standard diagnosis. Pooled estimates of diagnostic test accuracy were produced using random-effects bivariate metaanalysis.
Objectives: To determine the diagnostic accuracy of the Whooley questions in the identification of depression; and, to examine the effect of an additional 'help' question.
Design: Systematic review with random effects bivariate diagnostic meta-analysis. Search strategies included electronic databases, examination of reference lists, and forward citation searches.
Objective: The Patient Health Questionnaire (PHQ-9) is a widely used screening tool for major depressive disorder (MDD), although there is debate surrounding its diagnostic properties. For the PHQ-9, we aimed to: 1. Establish the diagnostic performance at the standard cutoff point (10).

Several government reports have highlighted the need for better parenting interventions in at-risk groups. This report was commissioned to evaluate the clinical effectiveness and cost-effectiveness of parenting interventions for children with severe attachment problems (the main review).

Objectives: To assess the diagnostic test accuracy of screening measures for mental health problems in young people who offend; to evaluate the clinical effectiveness and cost-effectiveness of screening and treatment; to model estimates of cost; to assess the evidence base for screening against UK National Screening Committee criteria; and to identify future research priorities.
Data Sources: In total, 25 electronic databases including MEDLINE, PsycINFO, EMBASE and The Cochrane Library were searched from inception until April 2011.
Background: The depression module of the Patient Health Questionnaire-9 (PHQ-9) is a widely used depression screening instrument in nonpsychiatric settings. The PHQ-9 can be scored using different methods, including an algorithm based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and a cut-off based on summed-item scores. The algorithm was the originally proposed scoring method to screen for depression.

The present study used magnetoencephalography (MEG) to study responses within the first half second, to phobogenic stimuli in a group of individuals with spider phobia prior to treatment (n=12) and then in nine of them following successful CBT (where they could touch and manage live large common house spiders) at least 9 months later. We also compared responses to a group of age-matched healthy control participants (n=11).
View Article and Find Full Text PDFBackground: The brief Patient Health Questionnaire (PHQ-9) is commonly used to screen for depression with 10 often recommended as the cut-off score. We summarized the psychometric properties of the PHQ-9 across a range of studies and cut-off scores to select the optimal cut-off for detecting depression.
Methods: We searched Embase, MEDLINE and PsycINFO from 1999 to August 2010 for studies that reported the diagnostic accuracy of PHQ-9 to diagnose major depressive disorders.
