An item response theory analysis of an item pool for the recovering quality of life (ReQoL) measure
The results from the IRT analyses confirm the robust structure properties and internal construct validity of the ReQoL instruments. The strong psychometric evidence generated guided item selection for the final versions of the ReQoL measures
Exploring the item sets of the Recovering Quality of Life (ReQoL) measures using factor analysis
The analyses confirmed that the ReQoL item sets are sufficiently unidimensional to proceed to item response theory analysis. The model was robust across different ordering of positive and negative items
Postwar environment and long-term mental health problems in former child soldiers in Northern Uganda
BACKGROUND: War experiences (WE) and postwar environments (PWE) are associated with mental ill-health. The present study aims to investigate the pathways from WE and PWE to mental ill-health and to define opportunities for intervention through analysis of the war-affected youths study (WAYS) cohort study. METHOD: WAYS is an ongoing study of a large cohort of former child soldiers being conducted in Uganda. Mental health problems, subjective WE an…
Comparing growth trajectories of risk behaviors from late adolescence through young adulthood
Risk behaviors such as substance use or deviance are often limited to the early stages of the life course. Whereas the onset of risk behavior is well studied, less is currently known about the decline and timing of cessation of risk behaviors of different domains during young adulthood. Prevalence and longitudinal developmental patterning of alcohol use, drinking to the point of drunkenness, smoking, cannabis use, deviance, and HIV-related sexual…
Usefulness of EQ-5D for evaluation of health-related quality of life in young adults with first-episode psychosis
The validity of subjective quality of life measures in psychotic patients with severe psychopathology and cognitive deficits
An Evaluation of the Precision of Measurement of Ryff's Psychological Well-Being Scales in a Population Sample
The aim of this study is to assess the effective measurement range of Ryff's Psychological Well-being scales (PWB). It applies normal ogive item response theory (IRT) methodology using factor analysis procedures for ordinal data based on a limited information estimation approach. The data come from a sample of 1,179 women participating in a midlife follow-up of a national birth cohort study in the UK. The PWB scales incorporate six dimensions: au…
Biased Mentalizing in Children Aged Seven to 11
A new approach to the measurement of mentalizing is introduced. Instead of measuring the presence or absence of mentalizing capacity, the current study aimed at developing a mentalizing task that focuses on investigating biases in mentalizing through the use of ambiguous peer‐related social scenarios. The response consistency of 659 children was investigated in a community sample of children aged seven to 11. Confirmatory latent class analysis al…
Association Between Duration of Untreated Psychosis and Outcome in Cohorts of First-Episode Patients
CONTEXT: Duration of untreated psychosis (DUP) is the time from manifestation of the first psychotic symptom to initiation of adequate treatment. It has been postulated that a longer DUP leads to a poorer prognosis. If so, outcome might be improved through earlier detection and treatment. OBJECTIVES: To establish whether DUP is associated with prognosis and to determine whether any association is explained by confounding with premorbid adjustment…
