Aspects of Identity Questionnaire-IV: An Examination of Structural Validity, Gender Invariance, and Relationships with Mental Health and Basic Psychological Needs Among Adolescents.

The present research evaluated evidence for structural and convergent validity and measurement invariance across gender of the Aspects of Identity Questionnaire-IV (AIQ-IV), which is designed to measure four identity orientations: Personal, Relational, Public, and Collective. We recruited two independent samples of Serbian adolescents aged 15-19 years (n1 = 436, n2 = 452). Both exploratory structural equation modeling (ESEM) and confirmatory factor analyses (CFA) were applied to examine the factor structure of the AIQ-IV. The ESEM model with four factors demonstrated a superior fit to the data in both samples and resulted in well-defined factors and deflated latent factor correlations compared to the CFA model. Multiple-group analysis supported the scalar invariance of the four-factor ESEM model across gender. The evidence for the convergent validity of the ESEM AIQ-IV factors was supported by meaningful correlations with various mental health indicators (life satisfaction, positive affect, negative affect, internalizing behaviors, and externalizing behaviors) and basic psychological needs (autonomy, relatedness, and competence) satisfaction and frustration. Our findings support the use of AIQ-IV as a multidimensional measure of identity orientations among adolescents and confirm the usefulness of applying the ESEM framework to evaluate the validity aspects of this scale.

Intentions to be Vaccinated Against COVID-19: The Role of Prosociality and Conspiracy Beliefs across 20 Countries.

Understanding the determinants of COVID-19 vaccine uptake is important to inform policy decisions and plan vaccination campaigns. The aims of this research were to: (1) explore the individual- and country-level determinants of intentions to be vaccinated against SARS-CoV-2, and (2) examine worldwide variation in vaccination intentions. This cross-sectional online survey was conducted during the first wave of the pandemic, involving 6697 respondents across 20 countries. Results showed that 72.9% of participants reported positive intentions to be vaccinated against COVID-19, whereas 16.8% were undecided, and 10.3% reported they would not be vaccinated. At the individual level, prosociality was a significant positive predictor of vaccination intentions, whereas generic beliefs in conspiracy theories and religiosity were negative predictors. Country-level determinants, including cultural dimensions of individualism/collectivism and power distance, were not significant predictors of vaccination intentions. Altogether, this study identifies individual-level predictors that are common across multiple countries, provides further evidence on the importance of combating conspiracy theories, involving religious institutions in vaccination campaigns, and stimulating prosocial motives to encourage vaccine uptake.

The Youth Internalizing Problems Screener: Validation in Serbian Adolescents and Measurement Invariance across Serbia and the USA.

The Youth Internalizing Problems Screener (YIPS) is a recently developed measure of general internalizing problems in adolescence. Validity evidence supporting interpretation and use of the YIPS outside the USA is still limited, and no research to date has examined cross-national invariance of this scale. Using two samples of Serbian adolescents, the present study examined the factor structure, internal consistency reliability, and convergent and incremental validity of a Serbian language version of the YIPS. Following, we evaluated the measurement invariance of the YIPS across Serbian and USA samples. Evidence for a one-factor structure and good internal consistency for the Serbian YIPS was found. The scale scores yielded strong associations with measures of depression, anxiety, life satisfaction, and positive and negative affect, indicating evidence of convergent validity. YIPS scores also had a unique contribution over and above depression and anxiety in predicting subjective well-being, thus supporting incremental validity. Partial scalar invariance for the YIPS measurement model was indicated across Serbian and USA samples. We conclude the YIPS appears to be a psychometrically sound measure of general internalizing problems among Serbian adolescents.

Cross-Cultural Measurement of Positive and Negative Emotions in Adolescence: Evidence from Three Countries.

Cross-cultural assessment of affective well-being among adolescents has received scarce attention in positive psychological research. The present study investigated cross-cultural measurement invariance of the Scale of Positive and Negative Experience (SPANE) among adolescents from three countries (India, Poland, and Serbia). The sample included a total of 1080 adolescents (53.6% female; M age = 16.75, range = 15-19 years). Surveys were administered online in each country. Measurement invariance testing provided evidence for partial scalar invariance of the SPANE across cultures, with item "afraid" showing nonivariance across the three countries. Latent factor correlations between positive and negative emotions were stronger in Serbia compared to Poland and India. Positive emotions and life satisfaction had strong positive associations in all three countries (ranging from 0.68 to 0.75). The inverse correlations between negative emotions and life satisfaction were - 0.27, - 0.54, - 0.69 in India, Poland, and Serbia, respectively. Polish adolescents demonstrated the lowest levels of affective well-being, whereas Indian and Serbian adolescents did not differ substantially in levels of positive and negative emotions. The present study demonstrated that the SPANE is a reliable and useful tool for the assessment of positive and negative emotions among adolescents from different cultural settings.

The relationship between gender and life satisfaction: analysis across demographic groups and global regions.

This study sought to examine gender differences in life satisfaction globally and across demographic groups. The grouping variables included age, global region, marital status, employment status, education, and income. A sample of 1,801,417 participants across 166 countries was drawn from the Gallup World Poll. Given the hierarchical nature of the data, multi-level modeling was used for data analysis. Gender differences in life satisfaction were found to be significant yet small. Women reported higher levels of life satisfaction than men across all income, education, and employment groups. The direction of gender differences in life satisfaction was inconsistent across age and regional groups. Men scored higher than women only over the age of about 63, and in sub-Saharan Africa. Despite the less favorable objective conditions for women globally, women were found to be more satisfied with their lives than men across most of the groups we studied. It is hoped that the present results can be used to inform research and practice aiming to identify vulnerable female groups and to optimize the well-being of women globally.

Measuring life satisfaction among psychiatric patients: Measurement invariance and validity of the Satisfaction with Life Scale.

The main aim of the present study was to evaluate the measurement invariance and the convergent validity of the Satisfaction with Life Scale (SWLS) across clinical and nonclinical samples. A total of 216 psychiatric patients (47.7% females; Mage = 44.56) and 235 participants from the general population (54.5% females; Mage = 43.11 years) were recruited. The measurement invariance was tested by a multi-group confirmatory factor analysis. Full scalar invariance of the SWLS was supported. Psychiatric patients reported substantially lower life satisfaction than participants from the general population. The SWLS demonstrated good convergent validity in both samples. The present study supported the use of the SWLS as a measure of life satisfaction among psychiatric patients.

Intercomparison of airborne multi-angle polarimeter observations from the Polarimeter Definition Experiment.

In early 2013, three airborne polarimeters were flown on the high altitude NASA ER-2 aircraft in California for the Polarimeter Definition Experiment (PODEX). PODEX supported the pre-formulation NASA Aerosol-Cloud-Ecosystem (ACE) mission, which calls for an imaging polarimeter in polar orbit (among other instruments) for the remote sensing of aerosols, oceans, and clouds. Several polarimeter concepts exist as airborne prototypes, some of which were deployed during PODEX as a capabilities test. Two of those instruments to date have successfully produced Level 1 (georegistered, calibrated radiance and polarization) data from that campaign: the Airborne Multiangle Spectropolarimetric Imager (AirMSPI) and the Research Scanning Polarimeter (RSP). We compared georegistered observations of a variety of scene types by these instruments to test whether Level 1 products agreed within stated uncertainties. Initial comparisons found radiometric agreement, but polarimetric biases beyond measurement uncertainties. After subsequent updates to calibration, georegistration, and the measurement uncertainty models, observations from the instruments now largely agree within stated uncertainties. However, the 470 nm reflectance channels have a roughly +6% bias of AirMSPI relative to RSP, beyond expected measurement uncertainties. We also find that observations of dark (ocean) scenes, where polarimetric uncertainty is expected to be largest, do not agree within stated polarimetric uncertainties. Otherwise, AirMSPI and RSP observations are consistent within measurement uncertainty expectations, providing credibility for the subsequent creation of Level 2 (geophysical product) data from these instruments, and comparison thereof. The techniques used in this work can also form a methodological basis for other intercomparisons, for example, of the data gathered during the recent Aerosol Characterization from Polarimeter and Lidar (ACEPOL) field campaign, carried out in October and November of 2017 with four polarimeters (including AirMSPI and RSP).

The factor structure of the mental health continuum-short form (MHC-SF) in Serbia: an evaluation using exploratory structural equation modeling.

BACKGROUND: The Mental Health Continuum-Short Form (MHC-SF) is a brief measure to assess emotional, social, and psychological well-being. AIMS: We examined the factor structure of the MHC-SF in Serbia. A secondary goal was to examine measurement invariance and latent mean differences across gender. METHOD: The methods of Confirmatory Factor Analysis (CFA) and Exploratory Structural Equation Modeling (ESEM) were used to investigate the factor structure of the scale in a large sample (N = 1883). We compared 1-, 2-, and 3-factor models of mental well-being. RESULTS: The results supported the superiority of the 3-factor model of well-being over the alternatives. ESEM yielded better fit with the data and considerably smaller factor correlations than did CFA. ESEM also uncovered a number of cross-loadings in the MHC-SF. Full measurement invariance was established across gender, yet no significant gender differences were identified in the latent means. CONCLUSIONS: These results indicate that emotional, social, and psychological well-being represents correlated yet distinct factors in Serbia. The results also suggest that ESEM is a more appropriate method than CFA for examining the factor structure of mental well-being. The contributions of ESEM to current debates surrounding the distinction between hedonic and eudaimonic well-being are discussed.

The validity of the Satisfaction with Life Scale in adolescents and a comparison with single-item life satisfaction measures: a preliminary study.

PURPOSE: The validity of the life satisfaction measures commonly used among adults has been rarely examined in adolescent samples. The present research had two main goals: (1) to evaluate the structural validity of the Satisfaction with Life Scale (SWLS) among adolescents and to test measurement invariance across gender; (2) to compare the criterion and convergent validity of the SWLS and single-item life satisfaction measures among adolescents. METHODS: Three samples of Serbian adolescents were recruited for the present research. Study 1 (N = 481, M age = 17.01 years) examined the structure of the SWLS via confirmatory factor analysis (CFA) and evaluated measurement invariance of the SWLS across gender by a multi-group CFA. Study 2 (N = 283, M age = 17.34 years) and Study 3 (N = 220, M age = 16.73 years) compared the convergent validity of the SWLS and single-item life satisfaction measures. RESULTS: The results of Study 1 supported the original one-factor model of the SWLS among adolescents and provided evidence for strong measurement invariance of the SWLS across gender. The findings of Study 2 and Study 3 showed that the SWLS and single-item measures were equally valid and strongly associated (r = .734 in Study 2 and r = .668 in Study 3). No substantial differences in correlations with school success and well-being indicators were found between the SWLS and single-item measures. CONCLUSIONS: Our findings support the use of the SWLS among adolescents and indicate that single-item life satisfaction measures perform as well as the SWLS in adolescent samples.

The good, the bad (and the ugly): The role of curiosity in subjective well-being and risky behaviors among adolescents.

Previous studies have shown that enhanced trait curiosity has positive influence on well-being. It remains an open question, however, whether curiosity has any detrimental effects on behavioral outcomes in adolescence. The main aim of this research was to investigate the role of trait curiosity in the prediction of risky behavior engagement and subjective well-being (SWB) among adolescents. A total of 371 Serbian adolescents (mean age 15.5, SD = 0.57) participated in the 5-month follow up study. The results showed that the embracing component of curiosity (but not stretching) predicted risky behavior engagement, while the stretching component of curiosity (but not embracing) predicted positive affect. In addition, neither embracing nor stretching was a significant predictor of negative affect and life satisfaction. The results of this study call into question the conceptualization of curiosity as a completely positive emotional-motivational system, and suggest that curiosity can contribute to negative outcomes in adolescence.

The role of basic psychological needs in the relationships between identity orientations and adolescent mental health: A protocol for a longitudinal study.

Research into the role of identity orientations (the relative importance an individual places on different personal and social attributes and characteristics when defining her or his identity) in adolescent mental health is extremely limited. Furthermore, the potential mechanisms that might explain the associations between identity orientations and adolescent mental health are poorly understood. This study protocol describes a one-year longitudinal study across three time points to be initiated with the purpose of investigating the mediating role of basic psychological needs satisfaction and frustration in the relationship between identity orientations and various mental health indicators in adolescence. We aim to recruit a large sample of Serbian adolescents (N = 2,000 at Time 1), using a two-stage stratified random sampling. The data will be analyzed using the random intercept cross-lagged panel model (RI-CLPM), and the results will be contrasted with the traditional CLPM. The goal of this study is to make a theoretical contribution to research in the fields of identity, self-determination theory, and adolescent mental health, as well as to provide insights towards the development of evidence-based recommendations for creating prevention and promotion programs aimed at improving the well-being of adolescents.

The Coronavirus Anxiety Scale: Cross-national measurement invariance and convergent validity evidence.

Coronavirus Anxiety Scale (CAS) is a widely used measure that captures somatic symptoms of coronavirus-related anxiety. In a large-scale collaboration spanning 60 countries (Ntotal = 21,513), we examined the CAS's measurement invariance and assessed the convergent validity of CAS scores in relation to the fear of COVID-19 (FCV-19S) and the satisfaction with life (SWLS-3) scales. We utilized both conventional exact invariance tests and alignment procedures, with results revealing that the single-factor model fit the data well in almost all countries. Partial scalar invariance was supported in a subset of 56 countries. To ensure the robustness of results, given the unbalanced samples, we employed resampling techniques both with and without replacement and found the results were more stable in larger samples. The alignment procedure demonstrated a high degree of measurement invariance with 9% of the parameters exhibiting noninvariance. We also conducted simulations of alignment using the parameters estimated in the current model. Findings demonstrated reliability of the means but indicated challenges in estimating the latent variances. Strong positive correlations between CAS and FCV-19S estimated with all three different approaches were found in most countries. Correlations of CAS and SWLS-3 were weak and negative but significantly differed from zero in several countries. Overall, the study provided support for the measurement invariance of the CAS and offered evidence of its convergent validity while also highlighting issues with variance estimation.

Vaccination Attitudes Examination (VAX) Scale: a Bifactor-ESEM approach in a youth sample (15-24 years).

BACKGROUND: The Vaccination Attitudes Examination (VAX) Scale is a widely used scale designed to measure general attitudes toward vaccinations. However, evidence for the VAX's structural, convergent, and discriminant validity is still limited, especially in youth samples. METHODS: The present study examined the psychometric multidimensionality and evidence of convergent and discriminant validity of the VAX using the bifactor-exploratory structural equation modeling approach (bifactor-ESEM). Using a sample of 803 Serbian adolescents and young adults (Mage = 18.23, SDage = 2.66, age range = 15-24 years, 59.2% female), we contrasted the original four-factor model of the VAX with alternative solutions (ESEM, bifactor-CFA, and bifactor-ESEM), and investigated associations between vaccination attitudes and a variety of external criteria. RESULTS: The results supported the bifactor-ESEM solution with one general factor of vaccination attitudes and four specific factors (Mistrust of vaccine benefit, Worries about unforeseen future effects, Concerns about commercial profiteering, and Preference for natural immunity) as the best representation of the data. The general factor was well-defined, and three specific factors showed good validity and specificity after the general factor was taken into account. The results of convergent validity analyses showed that the general factor of vaccine attitudes and one specific factor (Mistrust of vaccine benefit) were good predictors of vaccine conspiracy beliefs, attitudes towards COVID-19 vaccination, intention to get vaccinated against COVID-19, and trust in healthcare. The remaining three specific factors' contributions to external criteria were generally weak and nonsignificant. Evidence of the discriminant validity of the VAX scores was supported by weak positive associations of the general factor with medical fears and paranoid worry. CONCLUSIONS: The present findings indicate that distinguishing general and specific components of vaccination attitudes offers a more nuanced assessment and understanding of vaccination attitudes.

Well-Being and the Pandemic: Trust in People Matters More Than Trust in Institutions.

Trust is an important correlate of well-being, and it plays an important moderating role against adversity. But does this conclusion also hold during pandemics? We address this question by investigating the role of interpersonal and institutional trust for well-being, as measured by five proxies, during the COVID-19 pandemic in Serbia. We also examined age and gender differences in the relationship between trust and well-being, and tested the protective role of trust among individuals whose well-being might be at risk during the pandemic. The sample included a total of 5776 Serbian adults (Mage = 37.00 years, 75% female). The results showed that interpersonal trust has a small but significant relationship with well-being, whereas institutional trust has negligible effects. We also found some evidence for the protective role of general interpersonal trust on well-being among individuals with poorer self-rated health and in a poorer financial situation. Our findings confirm the role of interpersonal trust for well-being in times of crisis, and support previous evidence indicating that promoting interpersonal trust should be a core goal of public policy.

Vaccine Conspiracy Beliefs Scale: Validation and Measurement Invariance in a Youth Sample.

The Vaccine Conspiracy Beliefs Scale (VCBS) is a widely used measure of conspiracy beliefs about vaccines, but evidence of its validity and measurement invariance, especially in youth samples, is still largely missing. The present study examined VCBS scores' factor structure, measurement invariance, convergent and discriminant validity, and incremental predictive validity. A sample of 803 Serbian youths (age range 15-24; 59.2% females) was recruited for the study. A modified single-factor model of the VCBS was supported, and showed evidence of full scalar invariance across gender, age, vaccination status, and personal history of COVID-19. Evidence of the VCBS scores' convergent and discriminant validity was obtained by examining associations with general conspiracy beliefs, vaccination attitudes, vaccination knowledge, intentions to get vaccinated against COVID-19, paranoia worries, fear of injections and blood draws, importance of God, self-rated health, and self-rated family's financial situation. The VCBS scores predicted a unique variance in the intention to get vaccinated against COVID-19, over and above vaccination attitudes and vaccination knowledge. The results suggest that the VCBS is a valid measure of vaccine conspiracy beliefs in youth.

Pandemic boredom: Little evidence that lockdown-related boredom affects risky public health behaviors across 116 countries.

Some public officials have expressed concern that policies mandating collective public health behaviors (e.g., national/regional "lockdown") may result in behavioral fatigue that ultimately renders such policies ineffective. Boredom, specifically, has been singled out as one potential risk factor for noncompliance. We examined whether there was empirical evidence to support this concern during the COVID-19 pandemic in a large cross-national sample of 63,336 community respondents from 116 countries. Although boredom was higher in countries with more COVID-19 cases and in countries that instituted more stringent lockdowns, such boredom did not predict longitudinal within-person decreases in social distancing behavior (or vice versa; n = 8,031) in early spring and summer of 2020. Overall, we found little evidence that changes in boredom predict individual public health behaviors (handwashing, staying home, self-quarantining, and avoiding crowds) over time, or that such behaviors had any reliable longitudinal effects on boredom itself. In summary, contrary to concerns, we found little evidence that boredom posed a public health risk during lockdown and quarantine. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Measurement Invariance of the Scale of Positive and Negative Experience Across 13 Countries.

The Scale of Positive and Negative Experience (SPANE) is widely used to measure emotional experiences, but not much is known about its cross-cultural utility. The present study evaluated the measurement invariance of the SPANE across adult samples (N = 12,635; age range = 18-85 years; 58.2% female) from 13 countries (China, Colombia, Germany, Greece, India, Italy, Japan, Poland, Portugal, Serbia, Spain, Turkey, and the United States). Configural and partial scalar invariance of the SPANE were supported. Three items capturing specific negative emotions (sad, afraid, and angry) were found to be culturally noninvariant. Our findings suggest that the SPANE's positive emotion terms and general negative emotion terms (e.g., negative and unpleasant) might be more suitable for cross-cultural studies on emotions and well-being, whereas caution is needed when comparing countries using the SPANE's specific negative emotion items.

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions, Age, and Gender.

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13-19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

Concern with COVID-19 pandemic threat and attitudes towards immigrants: The mediating effect of the desire for tightness.

Tightening social norms is thought to be adaptive for dealing with collective threat yet it may have negative consequences for increasing prejudice. The present research investigated the role of desire for cultural tightness, triggered by the COVID-19 pandemic, in increasing negative attitudes towards immigrants. We used participant-level data from 41 countries (N = 55,015) collected as part of the PsyCorona project, a cross-national longitudinal study on responses to COVID-19. Our predictions were tested through multilevel and SEM models, treating participants as nested within countries. Results showed that people's concern with COVID-19 threat was related to greater desire for tightness which, in turn, was linked to more negative attitudes towards immigrants. These findings were followed up with a longitudinal model (N = 2,349) which also showed that people's heightened concern with COVID-19 in an earlier stage of the pandemic was associated with an increase in their desire for tightness and negative attitudes towards immigrants later in time. Our findings offer insight into the trade-offs that tightening social norms under collective threat has for human groups.
