OBJECTIVES: The current study aimed at evaluating the reliability, convergent and divergent validity, and factor structure of the Spanish Launay-Slade Hallucinations Scale-Extended version (LSHS-E) in people with mental disorders and healthy controls. METHODS: Four hundred and twenty-two individuals completed the Spanish LSHS-E and the Spanish Community Assessment of Psychic Experiences. The convergent and divergent validity of the LSHS-E was assessed with the three dimensions of the Community Assessment of Psychic Experiences (positive, negative, and depressive dimensions) in healthy controls and people with a mental disorder...

OBJECTIVE: Epidemiological research plays an important role in public health, facilitated by the meta-analytic aggregation of epidemiological trials into a single, more powerful estimate. This form of aggregation is complicated when estimating the prevalence of a superordinate category of disorders (e.g., "any anxiety disorder," "any cardiac disorder") because epidemiological studies rarely include all of the disorders selected to define the superordinate category...

OBJECTIVES: The study aims to investigate apparently contradictory evidence regarding racial/ethnic differences in perceived need for behavioral health treatment in two prominent surveys of the U.S. population, the National Comorbidity Survey Replication (NCS-R) and the National Survey of Drug Use and Health (NSDUH). METHODS: The two surveys were compared with respect to two components of perceived need: service use and perceived need among the untreated. Logistic regression models were estimated to adjust comparisons for demographic characteristics...

OBJECTIVES: There is a need for a brief, reliable, valid, and sensitive assessment tool for screening cognitive deficits in patients with Major Depressive Disorders. This paper examines the psychometric characteristics of THINC-it, a cognitive assessment tool composed of four objective measures of cognition and a self-rated assessment, in subjects without mental disorders. METHODS: N = 100 healthy controls with no current or past history of depression were tested on four sequential assessments to examine temporal stability, reliability, and convergent validity of the THINC-it tests...

OBJECTIVES: Fried () quantified the overlap of items among seven widely used depression rating scales. The analysis revealed substantial heterogeneity of the depressive syndromes and a low overlap among the scales. To our best knowledge, there are no studies evaluating the content overlap of (hypo)mania scales. The goal of our study, therefore, is to quantify the overlap of items among seven widely used (hypo)manic scales, implementing the methodology developed by Fried (). METHODS: Seven commonly used (hypo)manic scales underwent content analysis...

OBJECTIVE: We investigated the quality of randomized controlled trials (RCTs) that included direct comparisons of psychotherapy for adults with an eating disorder (ED). METHOD: Thirty-five direct comparison RCTs of psychotherapy for adults diagnosed with an ED were rated using the Randomized Controlled Trials Psychotherapy Quality Rating Scale (RCT-PQRS). RESULTS: The mean total RCT-PQRS score (mean = 28.26; SD = 7.04) was in line with those that were reported for RCTs of psychotherapy for depression and anxiety disorders...

OBJECTIVES: Many studies indicate that bipolar disorders are underdiagnosed. Yet from 2007 to 2008, a series of publications asserted that bipolar disorders were being overdiagnosed. This review examines the methods used in the studies that reported bipolar disorders were being overdiagnosed. METHODS: A literature search for studies with original data related to overdiagnosis of bipolar disorders was performed. RESULTS: Four studies were found indicating bipolar disorders were being overdiagnosed...

OBJECTIVES: The aims of the study were to translate into Persian and culturally adapt the Kessler Psychological Distress Scales, K10 and K6, and to assess their reliability and validity. METHOD: The sample was recruited from primary health care (PHC) settings by quota nonprobability sampling, stratified by sex and age. Validity was assessed against the Composite International Diagnostic Interview (v2.1). The psychometric properties of K6 and K10 were also compared with the 12-item General Health Questionnaire (GHQ-12)...

OBJECTIVES: Emotional lability (EL) is an important trans-diagnostic concept that is associated with significant functional impairment in childhood and adolescence. EL is typically measured with questionnaires, although little is known about the ecological validity of these ratings. In this paper, we undertook 2 studies addressing this issue by examining the relationship between rating-based measures of EL and directly measured emotional expressions and experiences. Furthermore, the associations between directly measured emotional expressions and experiences and attention-deficit/hyperactivity disorder (ADHD) symptomatology were also examined, given the clear association of EL with ADHD in former research...

OBJECTIVES: It is well-known that in cross-sectional analyses, agreement between informants is modest as best when rating attention-deficit/hyperactivity disorder and other disruptive behaviour disorder symptoms. We here aimed to develop recommendations for the use of multi-informant data in the context of longitudinal developmental analyses that examine symptom trajectories over time. METHOD: Using parallel process modelling, we estimated parent-teacher agreement in inattention and hyperactivity/impulsivity symptom initial levels and slopes across the elementary school years (ages 7, 9, and 11) for a community sample of n = 1,388 youth...

OBJECTIVES: Conventional approaches to quality of life (QoL) measurement rely heavily on verbal, language-based communication. They require respondents to have significant cognitive and verbal ability, making them potentially unsuitable for people with severe mental health problems. To facilitate an alternative approach to QoL assessment, the current study aims to develop an alternative, visual representation of QoL for people with severe mental health problems. METHODS: An alternative, visual adaptation of the concept mapping method was used to construct this visual representation of QoL...

OBJECTIVES: We employed the correspondence analysis (CA) biplot to estimate correlations between gender-age levels of cardiovascular disease patients and their psychiatric and physical symptoms. Utilization of this correlation estimation can inform clinical practice by elucidating associations between certain psychiatric or physical symptoms and specific gender-age levels. METHOD: The CA biplot utilized here was designed to visually inspect row-column category associations in a 2-dimensional plane and then to numerically estimate the category associations with correlations...

OBJECTIVE: This study examines the reliability and validity of the Mood and Feelings Questionnaire (MFQ) and Short Mood and Feelings Questionnaire (SMFQ) for measuring depression in New Zealand help-seeking adolescents. METHOD: A sample of 183 adolescents completed the 33-item MFQ, which includes all 13 items on the SMFQ, at three time points during a trial of a computerized intervention for depression. RESULTS: Both the MFQ and SMFQ demonstrated good to excellent Cronbach's alphas, moderate to strong item-total score correlations, moderate to strong correlations with quality of life and anxiety measures, and strong correlations with the clinician-rated Children's Depression Rating Scale-Revised and the Reynolds Adolescent Depression Scale 2 at all time points, indicating good reliability and content, convergent, and concurrent validities, respectively...
