The way people with psychosis psychologically adapt and manage the diagnosis of such a mental disorder has been considered a key factor that contributes to the emergence and aggravation of emotional problems. These beliefs about illness can be very important due to their possible association with stigma and its implications in terms of loss of roles and social status. Given the importance of these personal beliefs about the specific diagnosis of psychosis, the Personal Beliefs about Illness Questionnaire (PBIQ) and PBIQ-R have been developed.

The present study aims to explore the psychometric characteristics of the Spanish version of the PBIQ-R in a sample of patients with a diagnosis of psychosis-related disorders.

Participants were 155 patients (54.8% male) of the Public Health Service in Andalusia (Spain). Those who consented to participate filled in the PBIQ-R, the Social Comparison Scale, and the PHQ-9 and GAD-7 to measure emotional symptoms.

All dimensions showed adequate internal consistency values: Cronbach’s alpha extends between .81 and .88; and McDonald’s omega ranges between .87 and .92. The temporal reliability for an interval of 3–4 weeks was high. The correlations between the PBIQ-R dimensions and the other variables included in the study were significant and in the expected direction. The factor analysis of the principal components of the PBIQ-R dimensions revealed a single factor in each of the dimensions that explained 64–74%.

The results support the reliability and validity of the Spanish version of the PBIQ-R.

The Work and Social Adjustment Scale (WSAS) is an instrument that can be easily applied for routine evaluation of the impact of mental disorders on patient functioning. In spite of the interest in its use, there is very little information available on its psychometric characteristics and even less in Spanish.

The objective of this study was to analyse its psychometric characteristics.

The sample consisted of 441 patients treated in a community mental health unit. They filled out the WSAS and two psychopathology measures, one for anxiety and the other for depression. Fifty-five of them, chosen at random, were asked to fill out the scale again a second time to explore its temporal reliability.

The scale showed high internal consistency, a single factor that explained 60.4% of the variance, and temporal reliability of .78 for the total score. Significant correlations were found between the WSAS scores and the psychopathological measures, as well as significant differences between those working and those on leave.

The results confirm the validity and reliability of the scale and support its possible use for routine evaluation of the functional impact of mental disorders.

The main aim of this study was to assess the psychometric proprieties of the Child Feeding Questionnaire (CFQ) in Italian mothers.

Mothers completed the Italian version of the CFQ, and children’s anthropometric data were collected. Construct validity of the CFQ was assessed by comparing three different models: (a) a seven correlated factors model in which all items were analysed; (b) a seven correlated factors model with composite items based on the Restriction factor and (c) an eight correlated factors model with a separate Reward factor. Measurement invariance using BMI categories and gender was evaluated. Furthermore, discriminant validity with group comparison was performed between BMI categories and gender.

Italy.

A total of 1253 6-year-old Italian children (53·9 % male) attending elementary school (1st grade) and their mothers (mean age = 38·22 years; sd = 4·89) participated in this study.

The eight-factor model with a separate reward factor provided the best fit for the data. The strict invariance of the CFQ across child BMI categories and gender was confirmed. The CFQ internal consistency was acceptable for most subscales. However, two subscales showed no adequate values. As expected, the CFQ scales showed significant differences between BMI categories, while no gender-related differences were found.

The study indicated the Italian version of the CFQ to be factorially valid for assessing parental feeding practices of 6-year-old children across BMI categories. Future research should address low internal consistency in some of the CFQ subscales.
