“…6,9,16,18–22 However, structures often differed depending on the version of the LSHS used in each study. This study replicated the 4-factor structure of the LSHS-E as reported by previous studies,13,20,21 providing some consistency for 4-factors of the propensity to experience HLEs in the general population. Moreover, this version fully matches the factor-structure reported by Larøi 9 in one of the original studies.…”

“…However, depending on the response format used and the number of items included in the scale, different factorial structures were found. These structures included 2-factor, 10,15 3-factor, 6,17–19 4-factor, 9,13,20–22 and 5-factor 16 models. Furthermore, despite the globalization of research on the factor structure of the LSHS-Extended (LSHS-E), no study to date has explored the measurement invariance of this tool across countries and clinical status.…”

Hallucination-like experiences (HLEs) are typically defined as sensory perceptions in the absence of external stimuli. Multidimensional tools, able to assess different facets of HLEs, are helpful for a better characterization of hallucination proneness and to investigate the cross-national variation in the frequencies of HLEs. The current study set out to establish the validity, factor structure, and measurement invariance of the Launay-Slade Hallucinations Scale-Extended (LSHS-E), a tool to assess HLEs. A total of 4419 respondents from 10 countries were enrolled. Network analyses between the LSHS-E and the 3 dimensions of the Community Assessment of Psychic Experiences (CAPE) were performed to assess convergent and divergent validity of the LSHS-E. Confirmatory factor analysis was used to test its measurement invariance. The best fit was a 4-factor model, which proved invariant by country and clinical status, indicating cross-national stability of the hallucination-proneness construct. Among the different components of hallucination-proneness, auditory-visual HLEs had the strongest association with the positive dimension of the CAPE, compared with the depression and negative dimensions. Participants who reported a diagnosis of a mental disorder scored higher on the 4 LSHS-E factors. Small effect size differences by country were found in the scores of the 4 LSHS-E factors even after taking into account the role of socio-demographic and clinical variables. Due to its good psychometric properties, the LSHS-E is a strong candidate tool for large investigations of HLEs.

“…Since items with this kind of content partially depend on depression levels, they should be considered for exclusion when the intention is to measure PLEs specifically, rather than, for example, screening for psychosis risk, where depression is a relevant risk factor of its own, and conceptual disentanglement is less critical. Our results did not conflict with the findings of Siddi et al (34), as the Launay-Slade Hallucinations Scale-Extended version does not include a non-specific item corresponding to PQ-B item 12, or an item that can be interpreted as body dysmorphia.…”

“…As PLEs appear more frequently among those with depressive symptoms ( 23 ), and general-population psychopathology has even been conceptualized as a single factor ( 33 ), it is still unclear to what degree responses to PLE items are driven by general psychopathology rather than specific experiences. Measurement invariance between those with and without psychopathology has been suggested for one measure of PLE ( 34 ), but their findings leave room for interpretation, as they applied loose criteria.…”

Measurement Invariance of Psychotic-Like Symptoms as Measured With the Prodromal Questionnaire, Brief Version (PQ-B) in Adolescent and Adult Population Samples

et al. 2021

Valid measurement of group differences in self-reported psychotic-like experiences (PLEs) requires knowing any group-specific measurement properties of the instruments. We investigated the measurement invariance of the 21-item Prodromal Questionnaire–Brief (PQ-B) questionnaire across gender, ethnic minority/majority status, and presence of depressive symptoms in two different US non-clinical undergraduate samples (N = 1,099). For each item, endorsement of the experience and the associated distress were combined for analysis. A unidimensional model of the PQ-B fit the data well. Across genders, the PQ-B showed configural and metric, but not full scalar invariance; there were statistically significant differences in eight thresholds of six items, most being higher endorsement thresholds for self-identified females. Partial scalar invariance was also found for ethnic status, with five thresholds of three items being higher for the minority participants. For depressive symptomatology, defined as the top quintile by the Beck Depression Inventory–II, partial scalar invariance required dropping one item, after which there were statistically significant differences only in two response thresholds. Overall, a wide range of PLE questionnaire items were found to be robust to gender and ethnicity effects, strengthening confidence in found group differences in PLEs. Although full scalar invariance could not be ascertained for any of the group comparisons, the few found scalar differences across groups were small, with minimal impact on group PLE estimates. However, since PLEs are easily conceptually entangled with depression symptoms, similar items should be considered for exclusion if separable constructs are the target of investigation.

Elementary School Students’ Subjective Well-Being Before and During the COVID-19 Pandemic: A Longitudinal Study

First empirical results indicate that the COVID-19 pandemic has a negative impact on adolescents’ and adults’ subjective well-being. In the present study we focus on the subjective well-being of elementary school children before and after the first pandemic-related school lockdown and examine if possible declines in subjective well-being are especially pronounced for some groups, considering socio-economic status, migration background, and gender as moderators. We tested N = 425 elementary school students (mean age: M = 8.19; SD = 1.04) longitudinally with four measurement points (three before the school lockdown and one after) regarding their general life satisfaction, mood, and domain satisfaction regarding peers, family, and school. Piecewise growth curve models revealed a significant decline in positive mood and in satisfaction with the family. Decline in life satisfaction and satisfaction with peers nearly missed significance. The investigated moderators had no impact on the changes in subjective well-being. We conclude that the pandemic had detrimental effects on young children’s subjective well-being.
