The development and structural validity testing of the Person-centred Practice Inventory-Care (PCPI-C).

Person-centred healthcare focuses on placing the beliefs and values of service users at the centre of decision-making and creating the context for practitioners to do this effectively. Measuring the outcomes arising from person-centred practices is complex and challenging and often adopts multiple perspectives and approaches. Few measurement frameworks are grounded in an explicit person-centred theoretical framework. In the study reported in this paper, the aim was to develop a valid and reliable instrument to measure the experience of person-centred care by service users (patients)-The Person-centred Practice Inventory-Care (PCPI-C). Based on the 'person-centred processes' construct of an established Person-centred Practice Framework (PCPF), a service user instrument was developed to complement existing instruments informed by the same theoretical framework-the PCPF. An exploratory sequential mixed methods design was used to construct and test the instrument, working with international partners and service users in Scotland, Northern Ireland, Australia and Austria. A three-phase approach was adopted to the development and testing of the PCPI-C: Phase 1 -Item Selection: following an iterative process a list of 20 items were agreed upon by the research team for use in phase 2 of the project; Phase 2 -Instrument Development and Refinement: Development of the PCPI-C was undertaken through two stages. Stage 1 involved three sequential rounds of data collection using focus groups in Scotland, Australia and Northern Ireland; Stage 2 involved distributing the instrument to members of a global community of practice for person-centred practice for review and feedback, as well as refinement and translation through one: one interviews in Austria. Phase 3: Testing Structural Validity of the PCPI-C: A sample of 452 participants participated in this phase of the study. Service users participating in existing cancer research in the UK, Malta, Poland and Portugal, as well as care homes research in Austria completed the draft PCPI-C. Data were collected over a 14month period (January 2021-March 2022). Descriptive and measures of dispersion statistics were generated for all items to help inform subsequent analysis. Confirmatory factor analysis was conducted using maximum likelihood robust extraction testing of the 5-factor model of the PCPI-C. The testing of the PCPI-C resulted in a final 18 item instrument. The results demonstrate that the PCPI-C is a psychometrically sound instrument, supporting a five-factor model that examines the service user's perspective of what constitutes person-centred care. This new instrument is generic in nature and so can be used to evaluate how person-centredness is perceived by service users in different healthcare contexts and at different levels of an organisation. Thus, it brings a service user perspective to an organisation-wide evaluation framework.

Correlations of the CNR1 Gene with Personality Traits in Women with Alcohol Use Disorder

Alcohol use disorder (AUD) is a significant issue affecting women, with severe consequences for society, the economy, and most importantly, health. Both personality and alcohol use disorders are phenotypically very complex, and elucidating their shared heritability is a challenge for medical genetics. Therefore, our study investigated the correlations between the microsatellite polymorphism (AAT)n of the Cannabinoid Receptor 1 (CNR1) gene and personality traits in women with AUD. The study group included 187 female subjects. Of these, 93 were diagnosed with alcohol use disorder, and 94 were controls. Repeat length polymorphism of microsatellite regions (AAT)n in the CNR1 gene was identified with PCR. All participants were assessed with the Mini-International Neuropsychiatric Interview and completed the NEO Five-Factor and State-Trait Anxiety Inventories. In the group of AUD subjects, significantly fewer (AAT)n repeats were present when compared with controls (p = 0.0380). While comparing the alcohol use disorder subjects (AUD) and the controls, we observed significantly higher scores on the STAI trait (p < 0.00001) and state scales (p = 0.0001) and on the NEO Five-Factor Inventory Neuroticism (p < 0.00001) and Openness (p = 0.0237; insignificant after Bonferroni correction) scales. Significantly lower results were obtained on the NEO-FFI Extraversion (p = 0.00003), Agreeability (p < 0.00001) and Conscientiousness (p < 0.00001) scales by the AUD subjects when compared to controls. There was no statistically significant Pearson’s linear correlation between the number of (AAT)n repeats in the CNR1 gene and the STAI and NEO Five-Factor Inventory scores in the group of AUD subjects. In contrast, Pearson’s linear correlation analysis in controls showed a positive correlation between the number of the (AAT)n repeats and the STAI state scale (r = 0.184; p = 0.011; insignificant after Bonferroni correction) and a negative correlation with the NEO-FFI Openness scale (r = −0.241; p = 0.001). Interestingly, our study provided data on two separate complex issues, i.e., (1) the association of (AAT)n CNR1 repeats with the AUD in females; (2) the correlation of (AAT)n CNR1 repeats with anxiety as a state and Openness in non-alcohol dependent subjects. In conclusion, our study provided a plethora of valuable data for improving our understanding of alcohol use disorder and anxiety.

Financial performance of mutual and pension funds focused on the natural resources sector

The natural resource sector plays a critical role in advancing sustainable development. However, fossil fuels, precious metals, and mineral extraction require large investments, which mutual and pension funds may assume when allowing fund managers to fulfil their fiduciary duties. This study examines the financial performance of conventional, natural resource, energy, and precious metal-related mutual and pension funds, considering the effects of the COVID-19 pandemic. We adopted a five-factor model with a sample of 42 natural resource funds, 45 energy funds, 45 precious metal funds, and 2172 conventional funds from January 2016 to December 2022. The results indicate that driven by fund managers’ reverse stock-picking skills, the precious metal fund category reaches the lowest mean risk-adjusted return in relation to the energy, natural resources, and conventional fund categories. Additionally, the COVID-19 global health crisis negatively affected the mean risk-adjusted returns on the energy, precious metals, and conventional funding categories. A similar effect is observed in the natural resource pension fund category, while its matching mutual fund category achieves similar financial performance during the non-crisis and crisis periods.

Meta-analysis of associations between five-factor personality traits and problematic social media use

AbstractThis meta-analysis quantified the relationship between the five-factor model of personality and problematic social media use and identified moderators of this relationship. The analysis used a random-effects model to calculate a correlation for each factor and included 113 samples, with a total of 53,913 participants, identified from systematic searches of four databases. Moderator analyses were used to investigate potential causes of heterogeneity. The meta-analysis found that high neuroticism (r = .21, p < .001, 95% CI [.19, .23]), low conscientiousness (r = -.16, p < .001, 95% CI [-.19, -.13]), low agreeableness (r = -.07, p < .001, 95% CI [-.10, -.05]), and low openness (r = -.04, p = .001, 95% CI [-.06, -.02]) were significantly associated with problematic social media use. Several significant moderator effects were found. The meta-analysis contributes to the understanding of the relationship between individual characteristics and problematic social media use and provides information that might be useful in preventing and treating this behaviour.

The Gray Nine and Parallel Personality Patterns: Big Five, Dark Tetrad, and a "Well-Rounded Personality".

The vast literature on personality psychology generally focuses on neutral or socially beneficial personality traits such as the Five-Factor model (e.g., agreeableness, conscientiousness) or "dark" traits such as Machiavellianism, narcissism, psychopathy, and everyday sadism. However, the current synthesis of the literature indicates that the distinction between benign, malign, and neutral personality traits and facets is partly misguided. In fact, there are many objective and subjective measures that indicate that high agreeableness is not beneficial, while moderate grandiose narcissism is. Many, if not all of the traits are rather gray and socially and personally desired outcomes indicate that people who aim for a well-rounded personality should typically be clustered in the middle of the various personality spectrums. In addition, many of the personality traits are characterized by parallel patterns of good/bad relations to social and personal outcomes.

Symptom Checklist-90-Revised: Factor structure and relevance as a measure for the Hierarchical Taxonomy of Psychopathology model

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a recently proposed dimensional model of psychopathology that aims to provide a more comprehensive understanding of the organization of mental disorders. The Symptom Checklist-90-Revised (SCL-90-R) is a widely used self-report questionnaire that assesses nine broad dimensions of psychopathologies. The current study reexamined the optimum factor structure of the SCL-90-R (first aim), and its usefulness for the assessment of psychological dimensions from a HiTOP perspective (second aim). These were examined in a community sample of adolescents from Cyprus. A total of 839 adolescents (males = 352, females = 485; no response = 2) with ages ranging from 14 to 18 years [mean (SD) = 15.52 years (0.64 years)] completed the SCL-90-R and the Fünf-Faktoren-Fragebogen für Kinder (FFFK), a personality measure of the Five-Factor Model of personality. Relevant to the first aim, the findings showed the most support for an exploratory structural equal model, with the nine theorized SCL-90-R factors/dimensions. Relevant to the second aim, the SCL-90 dimensions of somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety were associated with the five factors in the FFFK as theoretically predicated by the HiTOP model. The SCL-90-R dimensions for paranoid ideation and psychoticism did not. The findings indicated reasonable support for the theorized nine-factor SCL-90 model; and the use of the SCL-90-R dimension scales of somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety for measuring the dimensions with similar names in the HiTOP model.

Personality traits and symptoms of anxiety and depression in patients with primary vitreous floaters.

We investigated personality traits and symptoms of anxiety and depression in patients with primary vitreous floaters. A U.K. sample of adult patients (> 18years old) with vitreous floaters of a minimum of three months severe enough to seek a consultation was assessed for personality traits (The Big Five Inventory (BFI)), symptoms of depression (Patient Health Questionnaire-9), and symptoms of anxiety (Generalized Anxiety Disorder Questionnaire-7). 149 patients participated in the study. Compared to the general population, our sample had a significantly increased score in the domain of BFI-neuroticism (3.27 vs 2.97, ρ < 0.0001, d = 0.38) and reduced score in the domain of extraversion (2.97 vs 3.24, ρ < 0.0001, d = 0.33). Female patients scored significantly higher than male patients on BFI-neuroticism (ρ = 0.01), and on BFI-agreeableness (ρ = 0.01). Age was positively correlated with BFI-Conscientiousness (r = 0.19, ρ = 0.02) and with BFI-Agreeableness (r = 0.20, ρ = 0.01). 36% of our sample had moderate to severe symptoms of depression, and 43% had moderate to severe symptoms of anxiety. Our study highlights the underlying psychological traits of patients with severe vitreous floaters and particular mental health needs that deserve further consideration by ophthalmological and vision science clinicians.

L2 listening in a digital era: Developing and validating the mobile-assisted self-regulated listening strategy questionnaire (MSRLS-Q)

Mobile technologies have transformed L2 listening. These technologies provide learners with an abundance of materials that transcend the limitations of traditional classroom instruction. Understanding how learners engage with such materials is crucial if teachers are to facilitate students' development of self-regulated listening strategies. This study reports on the development and validation of a new instrument, the Mobile-assisted Self-Regulated Listening Strategy Questionnaire (MSRLS-Q). Informed by a social cognitive understanding of self-regulation, items were generated from existing literature and semi-structured interviews with 16 Chinese undergraduate students. The questionnaire was validated through an exploratory factor analysis with 309 Chinese undergraduate students, followed by a confirmatory factor analysis with a separate sample of 327 students. Results confirmed a 31-item, five-factor model covering students' pre-, during- and post-listening strategies: Goal setting and mobile resource planning, Cognitive and metacognitive multimedia listening, Mobile-assisted motivational control, Structuring online social space, and Listening evaluation and adaptation. Structural equation modelling revealed that four of the five factors significantly predicted students’ international orientation to use English. The results emphasize self-regulated listening as a cyclical process reflective of cognitive, motivational, and social dimensions of strategy use. Implications for research and pedagogical use of the MSRLS-Q are discussed.

Development and initial validation of Personality Disorder Syndrome scales for the MMPI-3.

The purpose of the present study was to revise and update the MMPI-2-RF personality disorder (PD) syndrome scales for the Minnesota Multiphasic Personality Inventory-3 (MMPI-3). Study 1 describes the development of the MMPI-3 PD syndrome scales in three separate samples of community participants (n = 1,591), university students (n = 1,660), and outpatient mental health patients (n = 1,537). The authors independently evaluated each of the 72 new MMPI-3 items and rated them for appropriateness for scale inclusion and used various statistical procedures for final item selection. Ultimately, all 10 scales were revised, with nine incorporating items that were new to the MMPI-3. In Study 2, we subsequently validated the new MMPI-3 PD Syndrome scales against measures of traditional PD measures, trait measures of the Alternative Diagnostic and Statistical Manual of Mental Disorders, fifth edition-5 model of personality disorders (AMPD) and the five-factor model (FFM) of personality, and specific criterion measures of externalizing, psychopathy, narcissism, emotional dysregulation, and self-harm, in two samples of university students (ns = 489 and 645). With some exceptions, the results were generally supportive of the convergent and discriminant validities of the MMPI-3 PD Syndrome scales. The Histrionic PD scale in particular was associated with questionable results and diverged most strongly from the theoretical construct it was originally meant to reflect. Further continuous validation of the scales is needed, especially in clinical samples, but the findings to date are promising. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Examining the validity and factor structure of the ICD-11 trait domains.

The International Classification of Diseases, 11th Edition (ICD-11) includes a new personality disorder (PD) severity diagnosis that may be further characterized using up to five trait domain specifiers. Most of the previous studies have investigated the ICD-11 trait domains using self-report measures. The present study aimed to validate ICD-11 PD trait domains using a multimethod design in a community mental health sample (n = 336). We conducted two confirmatory factor analyses to examine the factor structure of the ICD-11 PD trait model, utilizing clinician-rating, self-report, and informant-report measures. Finally, we examined associations between clinician-rated, self-reported, and informant-reported ICD-11 trait domains with external criteria, specifically traditional PD symptoms and the five-factor model of normal personality. All clinician-rated, self-reported, and informant-reported domain scores loaded meaningfully on their expected factors when controlling for nontrivial method factors. Generally, the trait domains exhibited meaningful associations with conceptually relevant external criteria, although the anankastia domain exhibited more variability in its pattern of correlations across methods. Overall, the ICD-11 trait domain model shows promising reliability and validity, indicating good progress within the field of PD assessment toward a more useful PD operationalization.

Personality determinants of goal orientation in elite long-distance and mountain runners

Background and Study Aim. The achievement theory points to two motivational orientations that represent different views on an individual's perception of success. In sports, these aspects are closely associated with various individual characteristics and athletic achievements. The aim of the study is to determine the relationship between personality traits and aspects of goal orientation among long-distance and mountain runners of both genders. Material and Methods. The study involved 9 women aged 26 to 34 and 13 men aged 26 to 38 who were members of the national long-distance and mountain running teams (medallists at the Polish and European Championships in their disciplines). Among the participants there were graduate students. The Polish adaptation of Costa and McCrae’s NEO Five-Factor Inventory questionnaire was used to examine the level of personality traits. The level of goal orientation dimensions was determined using the Polish adaptation of the Task and Ego Orientation in Sport Questionnaire. Statistical analysis was performed using Statistica 13 software. Results. In the studied group of male athletic competitors, three significant relationships were observed: a negative correlation between ego orientation and both neuroticism and openness to experience; a negative correlation between the overall level of goal orientation and neuroticism. These results are explained by the relationship that occurs between emotional balance and resilience to criticism and the desire to compare oneself to others and the tendency to demonstrate superior skills in front of others. Conclusions. The findings underscore the importance of considering individual characteristics in athletic competition. Emphasis is placed on the necessity of assessing personality traits and goal orientation dimensions among student and competitive long-distance and mountain runners of both genders. Additionally, the significance of these factors in predicting sporting achievement is highlighted, suggesting avenues for further research and practical application.

Parent–child interactive behavior in a German sample of parents with and without a mental illness: model replication and adaption of the Coding Interactive Behavior system

Studies using observational measures often fail to meet statistical standards for both reliability and validity. The present study examined the psychometric properties of the Coding Interactive Behavior (CIB) System within a German sample of parent–child dyads. The sample consisted of 149 parents with and without a mental illness and their children [n experimental group (EG) = 75, n control group (CG) = 74] who participated in the larger Children of Mentally Ill Parents at Risk Evaluation (COMPARE) study. The age of the children ranged from 3 to 12 years (M = 7.99, SD = 2.5). Exploratory factor analysis supported a five-factor model of the CIB with items describing 1) parental sensitivity/reciprocity, 2) parental intrusiveness, 3) child withdrawal, 4) child involvement, and 5) parent limit setting/child compliance. Compared to international samples, the model was reduced by two independent dyadic factors. Testing for predictive validity identified seven items with predictive power to differentiate parental group membership. The CIB factors did not seem to be sufficiently sensitive to illustrate differences in interaction within a sample of parents with various mental illnesses. To apply the CIB to the described sample or similar ones in the future, additional measurement instruments may be necessary.

The mentoring experience of Jordanian pre-service science teachers

The purpose of this study is to examine Jordanian pre-service science teachers’ perceptions of their mentoring experience using the five-factor model of mentoring (personal attributes, system requirements, pedagogical knowledge, modeling, and feedback). This study uses a descriptive survey research design, and the Arabic version of the validated Mentoring for Effective Primary Science Teaching (MEPST) survey was administered electronically to collect responses from 49 participants. The data was summarized using descriptive statistics, and t-tests were conducted to test for significant differences in the perceived mentoring experiences between male and female Jordanian pre-service science teachers. The study supports efforts to validate the Arabic version of the MEPST survey. The means of the participants’ perceptions of mentoring were relatively high, greater than four on a five-point Likert scale, indicating that the pre-service teachers perceived their mentoring experience as positive based on the five factors. No statistically significant differences were found in the perceived effectiveness of the mentoring experiences between the male and female pre-service science teachers. The study findings have several practical implications and suggested directions for future research. Researchers are encouraged to investigate mentors’ perceptions and practices related to effective mentoring, and research on identifying and understanding school factors that may influence the effectiveness of mentoring in schools is also needed.

Enhancing image sentiment analysis: A user-centered approach through user emotions and visual features

To bridge the gap between user understanding of emotions and image representation, this paper amalgamated a variety of user features to formulate an image sentiment analysis model. Through controlled user experiments, participants were engaged in discerning sentiment from abstract painting images. User visual features were derived from eye-tracking data collected during the experiment. This paper employed the FFM (Five Factor Model) and POMS (Profile of Mood States) methodologies to gather personality and mood data, which were utilized as user emotional features. Additionally, fundamental components of abstract painting were captured as basic image features. By synergizing features across these three dimensions, the study introduced the "User-Feature-Enhanced-Image-Sentiment-Model" (UFE-ISM) for image sentiment recognition. The research findings underscore the model's superior performance in sentiment classification on abstract painting. Notably, both basic image features and user visual features exhibited significant contributions to the image sentiment classification model.

The Influence of Personality Traits on Postpartum Depression: A Systematic Review Based on the NEO-FFI Scale

Postpartum depression (PPD) is a significant global health concern with profound implications for mothers, families, and societies. This systematic review aims to synthesize current research findings to understand better how personality traits, as assessed by the NEO Five-Factor Inventory (NEO-FFI), contribute to the development and progression of PPD. Conducted in January 2024, this review searched major databases like PubMed, PsycINFO, and Scopus up to December 2023, focusing on the NEO-FFI’s role in evaluating PPD. Following PRISMA guidelines, studies were selected based on strict criteria, including the exclusive use of NEO-FFI for personality assessment and a focus on postpartum women. A total of seven studies were included after a rigorous two-step screening process, and their data were qualitatively synthesized. The review covered a total of 4172 participants, with a prevalence of clinically significant postpartum depression symptoms ranging from 10.6% to 51.7%. Notably, Neuroticism emerged as a significant predictor of PPD, with odds ratios ranging from 1.07 (95% CI: 0.96–1.20) in some studies to as high as 1.87 (95% CI: 1.53–2.27) in others. In contrast, traits like Extraversion and Conscientiousness generally showed protective effects, with lower scores associated with reduced PPD risk. For instance, Extraversion scores correlated negatively with PPD risk (Beta = −0.171) in one study. However, the impact of other traits such as Openness and Agreeableness on PPD risk was less clear, with some studies indicating negligible effects. The review highlights Neuroticism as a consistent and significant predictor of PPD risk, with varying impacts from other personality traits. The findings suggest potential pathways for targeted interventions in maternal mental health care, emphasizing the need for comprehensive personality evaluations in prenatal and postnatal settings.

Validating the Ego-Resiliency Questionnaire for Preadolescents (the ER-P) Using a Population-Based Sample From Korea

This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved configural, metric, and scalar levels of measurement invariance across gender. The ER-P scores exhibited correlations with personality traits of the five-factor model and general happiness, providing evidence of its convergent validity. This suggests that the ER-P has sound psychometric properties for evaluating ego-resiliency in Korean preadolescents. The validation of the ego-resiliency questionnaire specifically tailored for younger individuals marks a significant expansion of the ego-resiliency research domain, especially considering that existing instruments were initially designed for adults. The ER-P will be useful in education, counseling, and research settings that require information on preadolescents’ self-rated inner strength.

Using the five-factor model of personality to identify an optimal SWAT team member

This study, based on the five-factor model (FFM) of personality, aimed to identify personality traits associated with the most optimal special weapons and tactics (SWAT) team member. SWAT teams are tasked with pre-empting and responding to terrorist threats, conducting hostage rescue operations, and managing situations that exceed the capabilities of conventional law enforcement agencies. The study sought to provide a deeper understanding of how personality traits function within the high-stakes context of these teams. It involved 159 male SWAT officers in active service within the Swedish Police Authority. A work analysis instrument, the Personality Job Profiler (PJP), was administered to these officers, who served as subject matter experts (SMEs) in a comprehensive personality work analysis. Specifically, the study addressed two research questions: How can an optimal SWAT police officer personality profile be operationalized when translated to the FFM of personality? What is the association between this optimal SWAT profile and the ratings of ten Diagnostic and Statistical Manual of Mental Disorders personality disorder profiles, based on the FFM of personality? The findings suggest that successful SWAT officers should exhibit low neuroticism and high conscientiousness, specifically featuring low vulnerability and high levels of competence, dutifulness, and self-discipline. Notably, the SWAT profile differs significantly from personality disorders, such as borderline, schizotypal, dependent, and avoidant, when operationalized with the FFM of personality. These results have significant implications for developing predictors for the selection process and can enhance the selection procedures for future SWAT members. This may also prompt further studies on criteria-related validity using various personality assessment methods.

Explore the Impact of Homesickness, Depression, and Consciousness on Hosteled Students' Academic Procrastination

Background: Homesickness, an emotional state triggered by separation from familiar environments, has been identified as a significant factor affecting mental health and academic performance in students, particularly those living in hostels. Existing literature links homesickness with increased feelings of anxiety and depression, which in turn may contribute to academic procrastination. Objective: This study aimed to explore the relationships among homesickness, depression, conscientiousness, and academic procrastination in hosteled students, with an emphasis on understanding how these factors interact to influence academic outcomes. Methods: A correlational research design was employed to assess the impact of homesickness, depression, and conscientiousness on academic procrastination among 150 hosteled students. Standardized tools including the Yearning in Situations of Loss scale (YSL), Depression Anxiety Stress Scale (DASS), Big Five Inventory (BFI), and Academic Procrastination Scale (APS) were utilized for data collection. Pearson correlation coefficients and multiple regression analyses were conducted using SPSS version 25 to analyze the data. Results: Homesickness was significantly correlated with anxiety (r=.373, p&lt;.01) and stress (r=.33, p&lt;.01). Conscientiousness showed a positive correlation with gender (r=.204, p&lt;.05) and was associated with higher levels of academic procrastination (r=.28, p&lt;.01). Regression analysis revealed that homesickness did not significantly predict academic procrastination (β =-.089, p=ns). Additionally, depression was identified as a mediator in the relationship between homesickness and academic procrastination, although the indirect effects were minimal. Conclusion: The study highlights the complex interplay between homesickness, depression, and conscientiousness in influencing academic procrastination among hosteled students. It underscores the need for targeted interventions to address these psychological factors, potentially enhancing academic performance and well-being in this population.

Personality Traits and Internet Addiction among Adolescent Students: The Moderating Role of Family Functioning

Objectives: Internet addiction is a behavioral addiction characterized by excessive and compulsive use of the internet. The risk of internet addiction among adolescents has risen recently due to an increase in technological advancement and globalization. However, previous studies have focused on the precipitating factors triggering the internet addiction without looking at the exogenous factors and boundary conditions, such as family functioning, that can either sustain or weaken such behavior. Thus, the present study aimed to examine the moderating role of family functioning in the relationship between personality traits and internet addiction among adolescents. Methods: This study is a cross-sectional study consisting of 3150 adolescent students in the grade/class level of JSS1-SS3 who were assessed with standardized measures of the Big-Five Personality Inventory, Internet Addictive Test, and Family APGAR Index. Pearson correlation was used to explore the bivariate relationships between the demographic variable and other variables of interest, while Hayes regression-based PROCESS macro for SPSS was used to test the Hypotheses. Results: (1) Openness to experience, conscientiousness, extraversion, and neuroticism positively correlated with internet addiction, whereas agreeableness was negatively associated with internet addiction. (2) Positive family functioning correlated negatively with internet addiction. (3) Positive family functioning moderated the relationships of extraversion and agreeableness with internet addiction but not on openness to experience, conscientiousness, and neuroticism with internet addiction. Conclusions: Positive family functioning correlated negatively with internet addiction among adolescents, suggesting that improving family functioning would be a valuable tactic for reducing adolescents’ susceptibility to personality-related internet addiction.

A Pioneer Tool to Reduce Restrictive Practices toward People with Intellectual and Developmental Disabilities.

Reducing restrictive practices toward individuals with intellectual and developmental disabilities is a globally recognized imperative and human rights priority. This paper presents a novel tool called LibRe for assessing and reducing restrictive practices. This tool involved an instrumental multistage design and collaboration between professionals, individuals with disabilities, family members, and experts from different fields. It addresses diverse restrictive practices in five key domains: physical or mechanical, chemical or pharmacological, structural, relational, and practices related to contexts and supports. It addresses practices that are pertinent to the Spanish context and that existing tools have not covered. Embedded as a step within an organizational approach, LibRe fosters organizational transformation and provides resources to achieve outcomes within reduction plans for restrictive practices. In total, 156 teams comprising 585 professionals, 64 people with disabilities, and 44 family members responded to the tool. In terms of evidence for internal structure validity, the oblique five-factor model exhibited an adequate fit through confirmatory factor analysis, along with satisfactory reliability indices, according to ordinal alpha and omega. Users positively appraised the tool's usefulness and identified its strengths and challenges. Although further research is needed, preliminary evidence frames LibRe as a useful resource for practice and research.
