At the beginning of 2020, the entire world was shocked by a global health emergency. According to the literature, fear, high mortality and health restrictions had significant psychological consequences on the population. This study evaluates the French lockdown's impact on the grieving process and how people worked through their grief. Two semi-structured interviews were conducted with 31 participants who had lost a loved one between March 2020, June, and September 2021 (T0) and 6 months later (T1). Subsequently, they were divided into two groups: those who lost someone during the first lockdown (Group 1) and those who lost someone outside the lockdown periods (Group 2). The interviews were analysed using the ALCESTE software, a statistical analysis tool for textual data based on word co-occurrences. This research significantly advances the understanding of bereavement during crises, providing new perspectives and practical insights for policymakers, healthcare professionals and support organisations. Its methodological innovation and detailed analysis contribute to the ongoing discussion on grief and resilience in challenging circumstances. Ultimately, this study lays the foundation for improved support and intervention strategies tailored to the needs of bereaved individuals during crises.

This tutorial delves into dimensionality assessment within the context of psychological measurement instruments, particularly focusing on bifactor models. It underscores the imperative to move beyond traditional fit indices when evaluating factor structures while highlighting the significance of ancillary bifactor indices such as explained common variance, OmegaH and percentage of uncontaminated correlations in gaining a more comprehensive understanding of the interplay between general and specific group factors. The tutorial offers a step-by-step guide to leveraging the power of R software for confirmatory factor analysis and the acquisition of ancillary bifactor indices. Through practical case studies, it elucidates the potential pitfalls of exclusively relying on fit indices and advocates for a balanced, multifaceted approach to dimensionality assessment. By integrating fit measures and ancillary indices, researchers can draw more informed and nuanced conclusions about measurement instrument dimensionality, ultimately enhancing the precision of psychological assessment.

The objective of this study was to evaluate the feasibility of Virtual Motivational Interviewing (VIMINT) for improving physical activity among community-dwelling older adults. A feasibility study using a mixed-method single-group pre- and post-design. Each participant received five sessions of motivational interviewing (MI) through the Zoom platform. Feasibility and acceptability were assessed through recruitment, attrition and retention rates; adherence; satisfaction; counsellors' competency; and interviews with participants and counsellors. Other outcomes including physical activity were assessed at baseline, post- and 2-month follow-up. Eight participants were recruited; the mean age was 68.9 ± 3.9 years. The retention rate was 88%, 92.5% of the sessions were attended, and the participants' satisfaction score was 24.14 ± 7.3/32. The counsellors were rated as "good" and "fair" in relational and technical components, respectively. The categories derived from qualitative analysis were session composition, acceptability of outcome measures, positive impact of the VIMINT study and suggestions to improve future studies. The findings showed that VIMINT intervention should be feasible and acceptable for older adults. Evidence from this study provides relevant information that will guide the planning of future studies investigating the effectiveness of virtual MI on physical activity among community-dwelling older adults.

This tutorial introduces the graded response model (GRM), a tool for testing measurement precision within the item response theory (IRT) paradigm, which is useful for informing researchers about the item and person properties of their measurement. The tutorial aims to guide applied researchers through a unidimensional GRM analysis in the R environment, using the psych, mirt and ggmirt packages. GRM is specifically designed to examine the psychometric properties of psychological scales with polytomous (Likert-style) items. The tutorial illustrates the procedure using data from the Open Psychometrics Database on the right-wing authoritarianism (RWA) scale, outlining the theoretical underpinnings of GRM and steps for data preparation, testing model assumptions, model fitting, plotting item parameters and interpretation of results.

Moral self-efficacy refers to individuals' beliefs in their capability to effectively mobilise motivation, cognitive resources and strategic actions to achieve moral performance particularly in challenging situations. We adopt the conceptualization of moral self-efficacy that encompasses both self-reflective and behavioural components. The self-reflective dimension pertains to one's perceived capability to reflect on past moral lapses, while the behavioural dimension involves one's perceived capability to regulate future moral conduct. The study aims to explore moral self-efficacy as a "dynamic" process unfolding over time, focusing on the reciprocal influence between its self-reflective and behavioural dimensions in hindering the development of moral disengagement. Utilising a three-wave design with a sample of 1308 employees (50% females) at Time 1 results of a structural equation model support the hypothesized interplay between self-reflective and behavioural moral self-efficacy over time. In addition, our findings partly support our hypothesized relationships between moral self-efficacy dimensions and moral disengagement: self-reflective moral self-efficacy directly and negatively influenced the development of moral disengagement over time, while behavioural moral self-efficacy negative influenced it only indirectly through self-reflective moral self-efficacy.

We uncovered latent profiles of intergenerational and digital solidarity between middle-aged parents and their oldest young adult children during the COVID-19 pandemic. Furthermore, we investigated whether solidarity latent profiles were related to middle-aged parents' psychological well-being. We used data from the 2022 survey of the Longitudinal Study of Generations (LSOG), which involved 234 middle-aged parents providing information about their oldest young adult children. Using latent profile analysis, we uncovered five solidarity profiles (Tight-knit traditional, distant-but-digitally connected, obligatory, sociable, and conflictual) in relationships between middle-aged parents and their oldest young adult children during the pandemic. Furthermore, we found that middle-aged parents belonging to the distant-but-digitally connected and tight-knit traditional profiles had enhanced psychological well-being than those in the conflictual profile during the pandemic. These findings indicate that middle-aged parents' use of digital communication with young adult children benefited their psychological well-being during the pandemic. Moreover, using digital communication may be related to strong solidarity between middle-aged parents and young adult children when they live independently.

The present study examined the longitudinal relations among work self-efficacy beliefs, job performance and career success, defined as objective career advancements. We argued that job performance would mediate both the influence of worker's self-efficacy beliefs on career success and the influence of career success on subsequent self-efficacy beliefs. The participants were 976 employees of one of the largest companies in Italy, assessed at three time points (i.e., Waves 1, 2 and 3), spaced apart by 3 years. Job performance significantly mediated the relationship between self-efficacy beliefs and subsequent career success as well as the reverse influence of career success on subsequent self-efficacy beliefs. The posited conceptual model explained a significant portion of the variance in all endogenous variables and has implications for interventions intended to promote the development of individuals within organisations.

Caregivers who interact with children at home can provide a critical, complementary perspective on a child's behaviour functioning. This research used a parent-administered measure of problem behaviours to study perceptions of child behaviours across home situations. We applied latent profile analysis to identify subgroups of children with common behavioural tendencies in a nationally representative sample (N = 709) of 4- to 13-year-old children in Trinidad and Tobago. This study (a) identified latent profiles of children's over- and underactive behaviour problems in varied home settings and (b) examined how profile membership predicted academic skills and teacher-observed problem behaviours. The best-fitting four-profile model included one profile of adjusted behaviours (56%), one of the elevated attention-seeking behaviours (21%), a profile featuring withdrawn and disengaged behaviours (15%) and a relatively rare profile emphasising aggressive behaviours (8%). Children classified in the last profile displayed the poorest academic outcomes and the highest levels of teacher-observed behaviour problems.

Understanding the differential strength of effects in the presence of a third variable, known as a moderation effect, is a common research goal in many psychological and behavioural science fields. If structural equation modelling is applied to test effects of interest, the investigation of differential strength of effects will typically ask how parameters of a latent variable model are influenced by categorical or continuous moderators, such as age, socio-economic status, personality traits, etc. Traditional approaches to continuous moderators in SEMs predominantly address linear moderation effects, risking the oversight of nonlinear effects. Moreover, some approaches have methodological limitations, for example, the need to categorise moderators or to pre-specify parametric forms of moderation. This tutorial introduces local structural equation modelling (LSEM) in a non-technical way. LSEM is a nonparametric approach that allows the analysis of nonlinear moderation effects without the above-mentioned limitations. Using an empirical dataset, we demonstrate the implementation of LSEM through the R-sirt package, emphasising its versatility in both exploratory analysis of nonlinear moderation without prior knowledge and confirmatory testing of hypothesised moderation functions. The tutorial also addresses common modelling issues and extends the discussion to different application scenarios, demonstrating its flexibility.

Materialism is fundamental to the human value or goal system; therefore, an understanding of its level among Chinese college students and its changes over time is of great value. In the present study, a cross-temporal meta-analysis was performed by reviewing studies that conducted Material Values Scale-based assessment of the materialism level among Chinese university students from 2007 to 2020. Moreover, a time lag analysis was performed to clarify whether variations in materialism level are interpretable with macro-social indicators. Finally, 82 articles on studies enrolling a total of 45,966 Chinese university students were reviewed. The materialism score significantly increased on a yearly basis. Furthermore, macro-social changes in diverse areas, including economic condition (gross domestic product per capita, consumption level of all residents and national disposable income per capita), social connectedness (urbanisation degree and divorce ratio) and overall threat (rate of university enrollment), were the major factors influencing the degree of materialism among the students. By identifying the inclining trend of materialism among these college students across time and using relevant macro-social indicators, a theoretical three-dimensional framework was established to elucidate the degree of materialism among Chinese college students as a group.
