RESUMO

The risk of developing Alzheimer's disease (AD) significantly increases in individuals carrying the APOEε4 allele. Elderly cognitively healthy individuals with APOEε4 also exist, suggesting the presence of cellular mechanisms that counteract the pathological effects of APOEε4; however, these mechanisms are unknown. We hypothesized that APOEε4 carriers without dementia might carry genetic variations that could protect them from developing APOEε4-mediated AD pathology. To test this, we leveraged whole-genome sequencing (WGS) data in the National Institute on Aging Alzheimer's Disease Family Based Study (NIA-AD FBS), Washington Heights/Inwood Columbia Aging Project (WHICAP), and Estudio Familiar de Influencia Genetica en Alzheimer (EFIGA) cohorts and identified potentially protective variants segregating exclusively among unaffected APOEε4 carriers. In homozygous unaffected carriers above 70 years old, we identified 510 rare coding variants. Pathway analysis of the genes harboring these variants showed significant enrichment in extracellular matrix (ECM)-related processes, suggesting protective effects of functional modifications in ECM proteins. We prioritized two genes that were highly represented in the ECM-related gene ontology terms, (FN1) and collagen type VI alpha 2 chain (COL6A2) and are known to be expressed at the blood-brain barrier (BBB), for postmortem validation and in vivo functional studies. An independent analysis in a large cohort of 7185 APOEε4 homozygous carriers found that rs140926439 variant in FN1 was protective of AD (OR = 0.29; 95% CI [0.11, 0.78], P = 0.014) and delayed age at onset of disease by 3.37 years (95% CI [0.42, 6.32], P = 0.025). The FN1 and COL6A2 protein levels were increased at the BBB in APOEε4 carriers with AD. Brain expression of cognitively unaffected homozygous APOEε4 carriers had significantly lower FN1 deposition and less reactive gliosis compared to homozygous APOEε4 carriers with AD, suggesting that FN1 might be a downstream driver of APOEε4-mediated AD-related pathology and cognitive decline. To validate our findings, we used zebrafish models with loss-of-function (LOF) mutations in fn1b-the ortholog for human FN1. We found that fibronectin LOF reduced gliosis, enhanced gliovascular remodeling, and potentiated the microglial response, suggesting that pathological accumulation of FN1 could impair toxic protein clearance, which is ameliorated with FN1 LOF. Our study suggests that vascular deposition of FN1 is related to the pathogenicity of APOEε4, and LOF variants in FN1 may reduce APOEε4-related AD risk, providing novel clues to potential therapeutic interventions targeting the ECM to mitigate AD risk.

RESUMO

Background: Both genetic variants and epigenetic features contribute to the risk of Alzheimer's disease (AD). We studied the AD association of CpG-related single nucleotide polymorphisms (CGS), which act as the hub of both the genetic and epigenetic effects, in Hispanics decedents and generalized the findings to Non-Hispanic Whites (NHW) decedents. Methods: First, we derived the dosage of the CpG site-creating allele of multiple CGSes in each 1 KB window across the genome and we conducted a sliding window association test with clinical diagnosis of AD in 7,155 Hispanics (3,194 cases and 3,961 controls) using generalized linear mixed models with the adjustment of age, sex, population structure, genomic relationship matrix, and genotyping batches. Next, using methylation and bulk RNA-sequencing data from the dorsolateral pre-frontal cortex in 150 Hispanics brains, we tested the cis- and trans-effects of AD associated CGS on brain DNA methylation to mRNA expression. For the genes with significant cis- and trans-effects, we checked their enriched pathways. Results: We identified six genetic loci in Hispanics with CGS dosage associated with AD at genome-wide significance levels: ADAM20 (Score=55.2, P= 4.06×10 -8 ), between VRTN (Score=-19.6, P= 1.47×10 -8 ) and SYNDIG1L (Score=-37.7, P= 2.25×10 -9 ), SPG7 (16q24.3) (Score=40.5, P= 2.23×10 -8 ), PVRL2 (Score=125.86, P= 1.64×10 -9 ), TOMM40 (Score=-18.58, P= 4.61×10 -8 ), and APOE (Score=75.12, P= 7.26×10 -26 ). CGSes in PVRL2 and APOE were also genome-wide significant in NHW. Except for ADAM20 , CGSes in all the other five loci were associated with Hispanic brain methylation levels (mQTLs) and CGSes in SPG7, PVRL2, and APOE were also mQTLs in NHW. Except for SYNDIG1L ( P =0.08), brain methylation levels in all the other five loci affected downstream RNA expression in the Hispanics ( P <0.05), and methylation at VRTN and TOMM40 were also associated with RNA expression in NHW. Gene expression in these six loci were also regulated by CpG sites in genes that were enriched in the neuron projection and synapse (FDR<0.05). Conclusions: We identified six CpG associated genetic loci associated with AD in Hispanics, harboring both genetic and epigenetic risks. However, their downstream effects on mRNA expression maybe ethnic specific and different from NHW.

RESUMO

Weight-related abuse is defined as verbal or physical maltreatment specific to one's weight. The Weight-Related Abuse Questionnaire (WRAQ) is an instrument specifically designed to measure weight-related abuse. The main goal of this research was to study the factor structure and measurement invariance of the Spanish version of the WRAQ in a non-clinical and a clinical sample. The clinical sample included 150 participants with obesity (60 % women) from the Hospital de Valme (Sevilla, Spain). The non-clinical sample included 301 students (79 % women) from the Spanish Open University (UNED). Scales to measure weight self-stigma and fear of gaining weight were used to analyze the convergent validity of the WRAQ. A confirmatory factor analysis showed that a two-factor model (verbal and physical abuse) was an acceptable fit for the data in both the clinical and non-clinical samples. Multigroup Confirmatory Factor Analysis revealed scalar measurement invariance by sample and gender. Cronbach's alpha coefficients and composite reliability for both samples were found to be good, with values ranging from 0.83 to 0.96. Fear of gaining weight was correlated to verbal (r = 0.36, p < .01) and physical (r = 0.12, p < .05) abuse, and weight self-stigma was also related to physical (r = 0.21, p < .01) and verbal (r = 0.41, p < .01) abuse. These results suggest that the WRAQ can be used in clinical and non-clinical samples to assess verbal and physical abuse in both men and women.

RESUMO

The traits of the dark triad (narcissism, psychopathy, and Machiavellianism) capture the individual differences in the aversive personality. The dark triad has shown significant relations with behaviors that affect people's lives. One of the best-known instruments to assess the dark triad is the Dirty Dozen. However, controversy continues over the use of one general dark triad score or, conversely, three different scores. This study aimed to investigate the factor structure of the Dirty Dozen across eight global regions. There were 11,477 participants in 49 countries grouped into eight regions. Different factor structures were studied using confirmatory factor analyses. Both the three-dimensional models and the bifactor models (symmetrical or traditional and non-symmetrical or bifactor-[S - 1]) showed a good fit to the data. The bifactor-(S - 1) models (with psychopathy or Machiavellianism as the reference factors) show adequate fit to the data, supported by the coherence of the factorial loadings and the bifactor indices. Regarding measurement invariance for both models, configural, metric, and scalar invariance were satisfied. The results indicate that it is not clear whether a psychopathy or Machiavellianism reference factor predominates in the Dirty Dozen. For both models, templates are provided to obtain standardized scores for applied researchers in the eight studied world regions until future studies offer a greater amount of validity evidence for this instrument.

RESUMO

Importance: Cerebrospinal fluid (CSF) and plasma biomarkers can detect biological evidence of Alzheimer disease (AD), but their use in low-resource environments and among minority ethnic groups is limited. Objective: To assess validated plasma biomarkers for AD among adults of Caribbean Hispanic ethnicity. Design, Setting, and Participants: In this decision analytical modeling study, adults were recruited between January 1, 2018, and April 30, 2022, and underwent detailed clinical assessments and venipuncture. A subsample of participants also consented to lumbar puncture. Established CSF cut points were used to define AD biomarker-positive status, allowing determination of optimal cut points for plasma biomarkers in the same individuals. The performance of a panel of 6 plasma biomarkers was then assessed with respect to the entire group. Data analysis was performed in January 2023. Main Outcomes and Measures: Main outcomes were the association of plasma biomarkers amyloid-ß 1-42 (Aß42), amyloid-ß 1-40 (Aß40), total tau (T-tau), phosphorylated tau181 (P-tau181), glial fibrillary acidic protein (GFAP), and neurofilament light chain (NfL) with AD diagnosis. These biomarkers allow assessment of amyloid (A), neurofibrillary degeneration (T), and neurodegeneration (N) aspects of AD. Statistical analyses performed included receiver operating characteristics, Pearson and Spearman correlations, t tests, and Wilcoxon rank-sum, chi-square, and Fisher exact tests. Exposures: Exposures included age, sex, education, country of residence, apolipoprotein-ε4 (APOE-ε4) allele number, serum creatinine, blood urea nitrogen, and body mass index. Results: This study included 746 adults. Participants had a mean (SD) age of 71.0 (7.8) years, 480 (64.3%) were women, and 154 (20.6%) met clinical criteria for AD. Associations were observed between CSF and plasma P-tau181 (r = .47 [95% CI, 0.32-0.60]), NfL (r = 0.57 [95% CI, 0.44-0.68]), and P-tau181/Aß42 (r = 0.44 [95% CI, 0.29-0.58]). For AD defined by CSF biomarkers, plasma P-tau181 and P-tau181/Aß42 provided biological evidence of AD. Among individuals judged to be clinically healthy without dementia, biomarker-positive status was determined by plasma P-tau181 for 133 (22.7%) and by plasma P-tau181/Aß42 for 104 (17.7%). Among individuals with clinically diagnosed AD, 69 (45.4%) had plasma P-tau181 levels and 89 (58.9%) had P-tau181/Aß42 levels that were inconsistent with AD. Individuals with biomarker-negative clinical AD status tended to have lower levels of education, were less likely to carry APOE-ε4 alleles, and had lower levels of GFAP and NfL than individuals with biomarker-positive clinical AD. Conclusions and Relevance: In this cross-sectional study, plasma P-tau181 and P-tau181/Aß42 measurements correctly classified Caribbean Hispanic individuals with and without AD. However, plasma biomarkers identified individuals without dementia with biological evidence of AD, and a portion of those with dementia whose AD biomarker profile was negative. These results suggest that plasma biomarkers can augment detection of preclinical AD among asymptomatic individuals and improve the specificity of AD diagnosis.

RESUMO

PURPOSE: Weight self-stigma may be defined as a self-devaluation due to one's identification with the group of people with obesity. The Weight Self-Stigma Questionnaire (WSSQ) is an instrument specifically designed to measure weight self-stigma in populations with overweight or obesity. The objective of this study was to adapt the WSSQ to the Spanish population (S-WSSQ) following the guidelines for cross-cultural adaptations. METHODS: The sample comprised 165 participants with obesity seeking weight loss treatment (65% women) at the "Hospital de Valme" (Seville, Spain). Scales to measure life satisfaction, self-esteem, positive and negative affect, and antifat attitudes were used to analyze the convergent and divergent validity of the S-WSSQ. RESULTS: A confirmatory factor analysis showed adequate values of the goodness of fit indexes of a two-factor model (χ2/df = 2.01 CFI = 0.92, IFI = 0.92, SRMR = 0.08, RMSEA = 0.078), replicating the structure found by the original authors. Cronbach's alphas of the two factors were 0.76 (self-devaluation) and 0.77 (fear of enacted stigma). Composite Reliability values were 0.72 (self-devaluation) and 0.76 (fear of enacted stigma). Self-devaluation and fear of enacted stigma were negatively related to self-esteem, and positive affect, and positively related to negative affect and antifat attitudes. Finally, life satisfaction was negatively correlated to fear of enacted stigma. CONCLUSIONS: Based on these results, it is concluded that the S-WSSQ has good psychometric properties and might be used by the Spanish-speaking scientific community to measure weight self-stigma. LEVEL OF EVIDENCE: Level V, descriptive study.

RESUMO

PURPOSE: This study analyzes whether knowing that a male with obesity has a romantic relationship with a normal weight woman improves impressions about him. METHODS: An online experiment was conducted with a sample of 3024 adult participants (1828 women and 1196 men) with a mean age of 36.11 (SD = 13.49). Each participant was shown two photographs: one of a male target with obesity and one of his female partner (who had either normal weight or obesity depending on the condition). The respondents' sex was added as a fixed factor into the analyses. Physical attractiveness was rated using an item with a scale ranging from 0 to 100. Competence, warmth, and morality were measured using a 17-item adjective list. RESULTS: The target was assessed as more attractive when he had a partner with normal weight (F(1, 3009) = 4.85, p = .028, [Formula: see text] = .002), and was also given higher scores for competence (F(1, 3009) = 4.93, p = .026, [Formula: see text] = .002), warmth (F(1, 3009) = 4.32, p = .038, [Formula: see text] = .001), and morality (F(1, 3009) = 11.16, p = .001, [Formula: see text] = .004). There was a significant interaction between partner weight and the respondents' sex for physical attractiveness, as the difference between the scores in each condition was only significant for women. CONCLUSION: It is possible that women perceived that the male target who had a normal weight partner had a higher status or some hidden quality besides his physical appearance, and thus rated him as more attractive. LEVEL OF EVIDENCE: Level I, experimental study.

RESUMO

The main objective of this study was to examine the consequences of perceived discrimination in people with hearing and visual impairments. Using path analysis, we attempted to validate a multigroup model in which perceived personal discrimination is associated with internalization of stigma, which, in turn, is negatively related to self-esteem; conversely, perceived discrimination against the in-group contributes to enhanced group identification, which promotes the intention to engage in collective action, which, in turn, has beneficial effects on self-esteem. The sample consisted of a total of 200 Spanish-speaking participants, of whom 104 had hearing impairments and 96 had visual impairments. The results showed that the proposed multigroup model fit the data well. For both groups, internalized stigma played a mediating role in the relationship between perceived personal discrimination and self-esteem. However, the pathway from group discrimination to self-esteem was not as clearly supported by the data. The results are interpreted from a psychosocial perspective and may contribute to design interventions aimed at improving the well-being of people with hearing and visual impairments.

RESUMO

The objective of this study was to examine the relationships of participants' home characteristics (living space) and job prospects after the coronavirus disease 2019 (COVID-19) pandemic to their subjective psychological well-being (SWB) (in terms of both affective and cognitive aspects). We also examined the role of participants' resilience as a possible mediator in the relationships among the aforementioned variables. The sample comprised 474 Spanish adults who completed an online questionnaire between 14 and 24 April 2020, when COVID-19 confinement was very strict in Spain. We proposed a path analysis model including the described variables. The model presented a good fit (χ2 = 7.41, df = 5, p = 0.376, comparative fit index = 0.996, Tucker-Lewis index = 0.987; root mean square error of approximation = 0.032). The results indicated that living space and future job prospects predicted resilience, which, in turn, was related to SWB. Moreover, the bootstrapping results revealed a mediating effect of resilience that showed indirect relationships between living space and SWB and between job prospects and SWB. Our results underline the importance of environmental (living space) and job-related variables to predict SWB as well as the mediating role that resilience may play during the confinement period.

RESUMO

Parents' perception of the positive contributions associated with raising children with autism is considered to be a protective factor in the process of psychological adaptation. Thus, it is essential to unveil what factors are related to this perception. We explore how parents' psychological distress (parental stress and anxiety) predicts the perception of positive contributions in fathers and mothers who raise individuals with different levels of autism severity. The sample comprises 135 couples (270 fathers and mothers) parenting individuals diagnosed with autism aged 3-38 years. Participants completed different self-report questionnaires, including measures of parental stress, anxiety, and positive contributions. To estimate the actor-partner interdependence model, data were analyzed using structural equation modeling (SEM) to explore transactional effects between fathers' and mothers' psychological distress and their perceptions of positive contributions associated with autism. Two separate multigroup models were tested, respectively, analyzing parental stress and anxiety. Each multigroup model considers two levels of disorder severity. The findings revealed that actor and partner effects of stress and anxiety were important predictors of the perception of positive contributions in both disorder severity groups. We conclude that it is necessary to develop family support programs that focus on controlling fathers' and mothers' stress and anxiety symptoms, as these mental states negatively impact the ability to perceive positive contributions.

RESUMO

The main objective of this research is to examine the consequences of perceived discrimination in family caregivers of people with physical disabilities. Through path analysis, we test the association between caregivers' perceived discrimination and their anxiety and depression and the mediating role that affiliate stigma and self-efficacy may play. We proposed a model that has not been tested previously in the literature on caregivers of people with physical disabilities. The sample includes 186 Spanish fathers (35%) or mothers (65%) raising children with physical disabilities. Descriptive statistics and Pearson's correlation coefficients were calculated and structural equation modeling was used to examine the mediating effect. Results show that caregivers' perceived discrimination is positively associated with their affiliate or internalized stigma that in turn is harmful to their anxiety and depression. However, caregivers' self-efficacy plays a mediating role in the relation between affiliate stigma and caregivers' anxiety and depression. These results may be useful for designing interventions to improve the psychological well-being of the parents of children with physical disabilities.

RESUMO

This study was conducted with the purpose of analyzing the combined and mediating effect of actor's withdrawal-partner's demand conflict resolution strategies between avoidance attachment dimension and relationship satisfaction. We conducted a dyadic study with 175 heterosexual couples (aged between 18 and 72 years) who filled in the questionnaires. Six hypotheses were tested using the actor-partner interdependence model with mediation analysis (APIMeM). Results showed that the avoidance dimension of attachment was more strongly associated with actor's withdrawal strategy than with demand/aggression strategy. Furthermore, avoidance attachment was negatively associated with both actor's and partner's relationship satisfaction, the actor effect being higher. Withdrawal strategy was a mediator between actor's avoidance and actor's relationship satisfaction, but it was not a mediator for partner's relationship satisfaction. The interactive pattern of actor's withdrawal-partner's demand/aggression was associated with low levels of both actor's and partner's relationship satisfaction. These results point out to the need of discerning the interactive pattern of conflict-solving strategies as well as their intertwined effect on relationship satisfaction.

RESUMO

BACKGROUND: People with autism spectrum disorders (ASD) and people with intellectual disabilities (ID) are stigmatized, and therefore discriminated against worldwide and, on many occasions, this stigma and discrimination are expanded to include their family caregivers. The main objective of this research was to examine the consequences of perceived discrimination on family caregivers of children with ASD and children with ID. METHODS: The sample consisted of 109 Spanish caregivers of children with ASD and 83 caregivers of children with ID. They completed four questionnaires: Multidimensional Perceived Discrimination Scale, Affiliate Stigma Scale, Social Support Questionnaire and Rosenberg Self-Esteem Scale. RESULTS: Using path analysis, we found support for a model in which personal discrimination perceived by caregivers was positively associated with affiliate stigma, which, in turn, was negatively related to caregivers' self-esteem. The model also shows the total mediational role of affiliate stigma in the association between perceived discrimination and self-esteem and the partial mediational role that social support plays in the association between perceived discrimination and caregivers' self-esteem. CONCLUSIONS: Caregivers' perceived discrimination negatively influences caregivers' self-esteem, but this relationship is mediated by both affiliate stigma (totally) and social support (partially). These results have theoretical and practical implications and may contribute to improving the quality of life of parents of children with ASD and ID that in turn would result in an improvement of the quality of life of their children.

RESUMO

PURPOSE: The main objective of this study was to examine the role of social identification, collective action and resilience in reducing the negative consequences of internalized stigma on the psychological quality of life of people with physical disability using path analysis. We propose a model with two paths: the first through social identification and collective action and the second via resilience. METHOD: A total of 288 Spanish people with physical disability aged between 18 and 82 years (46.4% males; mean [SD] of age = 45.1 [12.3] responded to the questionnaire. Data were collected for three months through an online survey. RESULTS: The tested model adequately fit the data. We found that the relationship between internalized stigma and the psychological quality of life of people with physical disability was mediated by resilience. However, neither social identification nor collective action mediated the association between internalized stigma and quality of life among our participants. CONCLUSIONS: The results confirmed the negative association between internalized stigma and quality of life in the population with physical disability. The results show that some interactive processes, such as resilience, may contribute to decreasing the negative effects of internalized stigma. In contrast, no effects of identification with the group or collective action intention were found.

RESUMO

PURPOSE/OBJECTIVE: The aim of this study was to develop and test the psychometric properties of the Coping With Disability Difficulties Scale (CDDS), a scale to measure the coping strategies used by people with disabilities to face the disability-related difficulties (caused by both disability itself and by stigma) they encounter in their daily lives. METHOD/DESIGN: An initial pool of 110 items was developed based on previous literature and the results of a qualitative study using semistructured interviews. The psychometric characteristics of the CDDS were examined in 3 samples of people with disabilities (each of which included participants with physical, visual, and hearing impairments; total N = 590). RESULTS: A final scale of 17 items was obtained. The factor structure of the CDDS was tested and replicated with an adequate fit (root mean square error of approximation [RMSEA] = 0.056; goodness-of-fit index [GFI] = 0.98; comparative fit index [CFI] = 0.98) using confirmatory factor analysis. The internal consistency of the 4 factors (positive thinking, social sensitization and support, adaptation, and avoidance) was adequate to excellent (with alphas ranging from .68 to .86). CONCLUSIONS/IMPLICATIONS: To the authors' knowledge, this is the first coping scale that is specifically designed for people with disabilities, and it can be highly useful for both research and applied purposes.

OBJECTIVES: As reported in other high-income countries, around the 2008 Great Recession the Spanish banking sector engaged abusive practices that satisfy the definition of fraud. Our objective is to examine the association between self-reported bank fraud and physical health, using a gender perspective. METHODS: With data from the 2017 Madrid Health Survey, we examined the association between the economic impact of fraud and poor self-rated health (SRH), comorbidity and pain (N = 4425). Interactions of time since fraud and sex with economic impact were tested by Poisson regression models with robust variance. RESULTS: In total, 11% of adults in Madrid reported bank fraud since 2006. Among men, those who experienced frauds with severe economic impact were more likely to report adverse health than those who did not experience fraud (PR comorbidity: 1.46; PR pain conditions: 2.17). Among men time elapsed since fraud strengthened the association between severe economic impact and poor SRH (p = 0.022; p = 0.006, respectively). Among women, associations did not reach statistical significance. CONCLUSIONS: Bank frauds are an emerging phenomenon which is likely to damage public health. Stricter regulation to protect people from fraudulent bank practices is needed.

RESUMO

Over the past few decades, the financial system has engaged in abusive practices that meet the definition of fraud. Our objective is to compare the prevalence of psychological distress and levels of health-related quality of life according to having been exposed to financial fraud and its economic impact on family finances. The City of Madrid Health Survey 2017 included specific questions on exposure to financial fraud-this section was administered to half of the participants (n = 4425). Mental health need or caseness was defined by a score greater than two on the 12-item version of the Goldberg health questionnaire. Health-related quality of life was assessed by the Darmouth Coop Functional Health Assessment Charts/WONCA (COOP/WONCA). The prevalence of financial fraud was 10.8%. The prevalence rate ratio for caseness of those who experienced severe economic impact due to fraud was 1.62 (95%, CI 1.17-2.25; reference: no fraud), after adjustment by age, sex, social class, and immigrant status. Women experienced a decreased quality of life, even with a moderate impact of fraud, while men experienced a decreased quality of life related to fraud with severe economic impact. The current study contributes to a growing body of literature showing the effects of economic shocks on health as a result of financial fraud.

RESUMO

OBJECTIVE: To analyze the consequences for self-esteem of perceived discrimination against people with physical disabilities, as individuals and as a group. METHOD: A structural model based on the psychosocial literature was tested in a sample of 288 Spanish participants with different degrees of physical disability. This model predicted that personal perceived discrimination would be associated with the internalization of stigma that, in turn, would be negatively associated with the self-esteem of people with physical disabilities. On the other hand, group perceived discrimination, was predicted to enhance group identification and promote intention to contribute to collective action and hence have a beneficial effect on the self-esteem of people with physical disabilities. RESULTS: The model provided a good fit to the data. The relationship between personal discrimination and the self-esteem of people with physical disabilities was completely mediated by internalized stigma. The model also showed that group perceived discrimination had only an indirect effect on self-esteem. CONCLUSION: This research makes two main contributions. From a theoretical perspective we found that perceived personal and group discrimination influence self-esteem through different paths. From an applied point of view, our results may contribute to the design of interventions to enhance the quality of life of people with physical disabilities.

RESUMO

The Gratitude Questionnaire is a short, self-report measure of the disposition to experience gratitude. The Gratitude Questionnaire has been validated in several countries but its factor structure remains controversial. Therefore, the main goal of the study was to examine the factor structure of the Gratitude Questionnaire in a Spanish sample. Two samples were recruited (957 and 920 participants). The confirmatory factor analyses showed that the best fit was the five-item model with errors of item four and five correlated (CFI = .99, NFI = .99, RMSEA = .02). This model demonstrated partial cross-validity based on an analysis of factorial invariance. The Composite Reliability of the five-item Gratitude Questionnaire was .81. In addition, it was found that gratitude was positively related to subjective and psychological well-being. Specifically, the Gratitude Questionnaire was positively correlated to life satisfaction (r = .56, p < .01), affect balance (r = .46, p < .01), self-acceptance (r = .54, p < .01), positive relations (r = .44, p < .01), autonomy (r = .17, p < .01), environmental mastery (r = .49, p < .01), personal growth (r = .36, p < .01), and purpose in life (r = .50, p < .01). According to the results, it can be concluded that the Spanish version of the five-item Gratitude Questionnaire possessed better psychometric properties than the original six-item model.
