Validation of a general subjective well-being factor using Classical Test Theory

The ABC of happiness: Validation of the tridimensional model of subjective well-being (affect, cognition, and behavior) using Bifactor Polytomous Multidimensional Item Response Theory

Background

Happiness is often conceptualized as subjective well-being, which comprises people's evaluations of emotional experiences (i.e., the affective dimension: positive and negative feelings and emotions) and judgements of a self-imposed ideal (i.e., the cognitive dimension: life satisfaction). Recent research has established these two dimensions as primary parts of a higher order factor. However, theoretical, conceptual, and empirical work suggest that people's evaluations of harmony in their life (i.e., the sense of balance and capacity to behave and adapt with both acceptance and flexibility to inter- and intrapersonal circumstances) constitutes a third dimension (i.e., the behavioral dimension). This tridemensional conceptualization of subjective well-being has recently been verified using Unidimensional Item Response Theory (UIRT) and Classical Test Theory (CTT). Here, we use a recently developed and more robust approach that combines these two methods (i.e., Multidimensional Item Response Theory, MIRT) to simultaneously address the complex interactions and multidimensionality behind how people feel, think, and behave in relation to happiness in their life.

Method

A total of 435 participants (197 males and 238 females) with an age mean of 44.84 (sd = 13.36) responded to the Positive Affect Negative Affect Schedule (10 positive affect items, 10 negative affect items), the Satisfaction with Life Scale (five items), and the Harmony in life Scale (five items). We used Bifactor-Graded Response MIRT for the main analyses.

Result

At the general level, each of the 30 items had a strong capacity to discriminate between respondents across all three dimensions of subjective well-being. The investigation of different parameters (e.g., marginal slopes, ECV, IECV) strongly reflected the multidimensionality of subjective well-being at the item, the scale, and the model level. Indeed, subjective well-being could explain 64 % of the common variance in the whole model. Moreover, most of the items measuring positive affect (8/10) and life satisfaction (4/5) and all the items measuring harmony in life (5/5) accounted for a larger amount of variance of subjective well-being compared to that of their respective individual dimensions. The negative affect items, however, measured its own individual concept to a lager extent rather than subjective well-being. Thus, suggesting that the experience of negative affect is a more independent dimension within the whole subjective well-being model. We also found that specific items (e.g., "Alert", "Distressed", "Irritable", "I am satisfied with my life") were the recurrent exceptions in our results. Last but not the least, experiencing high levels in one dimension seems to compensate for low levels in the others and vice versa.

Conclusion

As expected, the three subjective well-being dimensions do not work separately. Interestingly, the order and magnitude of the effect by each dimension on subjective well-being mirror how people define happiness in their life: first as harmony, second as satisfaction, third as positive emotions, and fourth, albeit to a much lesser degree, as negative emotions. Ergo, we argue that subjective well-being functions as a complex biopsychosocial adaptive system mirroring our attitude towards life in these three dimensions (A: affective dimension; B: behavioral dimension; C: cognitive dimension). Ergo, researchers and practitioners need to take in to account all three to fully understand, measure, and promote people's experience of the happy life. Moreover, our results also suggest that negative affect, especially regarding high activation unpleasant emotions, need considerable changes and further analyses if it is going to be included as a construct within the affective dimension of a general subjective well-being factor.

Validity and internal consistency of four scales in patients with TMD: PHQ8, GAD7, PHQ15 and JFLS20

OBJECTIVES

The aim of this cross-sectional study was to explore the structural validity and internal consistency reliability of General Anxiety Disorder-7, Patient Health Questionnaire-8, 15 and Jaw Functional Limitation Scale-20 in patients with chronic pain of temporomandibular disorders.

MATERIALS AND METHODS

Validity and reliability were assessed in 129 patients diagnosed according to the diagnostic criteria for temporomandibular disorders. Structural validity was explored using factor analysis, and internal consistency by calculating Cronbach α.

RESULTS

Confirmatory factor analysis revealed a suitable 2-factor model for Patient Health Questionnaire-8, with Cronbach α of 0.89, and 0.86. One and 2-factor models were suitable for General Anxiety Disorder-7, with overall Cronbach α of 0.93 for the 1-factor model, and 0.91 and 0.84 for both factors in a 2-factor model. A 4-factor solution was appropriate for Patient Health Questionnaire-15, with Cronbach α of 0.72, 0.57, 0.71 and 0.73 for each factor separately. Exploratory factor analysis was conducted to explore the factor structure of Jaw Functional Limitation Scale 20, and a 3-factor solution was appropriate.

CONCLUSIONS

This study provides positive evidence of structural validity and internal consistency of these questionnaires in patients with pain of temporomandibular disorders. However, additional testing is required to explore further psychometric properties.

Beyond polarization towards dynamic balance: harmony as the core of mental health

Worldviews are culturally derived assumptions that influence individual and collective behaviors, values, and representations of reality. The study of mental functions is not exempt from this influence, as reflected in scientific theories, methodological approaches, and empirical studies. Despite acknowledging the interplay of mental processes with developmental, environmental, and cultural dimensions, psychological research is still primarily based on quantitative methods, and on the conceptualization of mental phenomena as unfolding along polarized continua. A lively epistemological debate surrounds this approach, especially underscoring the risk of blurring the distinction between constructs derived from statistical models and real-life processes and experiences. Based on this debate and on recent empirical evidence derived from the positive psychology literature, this paper is aimed at proposing an integrated view of mental health, as a holistically patterned, contextually imbedded, and dynamic phenomenon changing over time and across life events, with harmony, harmonization and dynamic balance as core qualities. The heuristic potential of investigating the qualitative configuration patterns of mental health dimensions across individuals and groups, beyond their position along a quantitative continuum, is outlined. The development of more integrated approaches and methodologies to investigate mental health as a harmonization process, taking into account personal, contextual and developmental features, would be aligned with evidence derived from the integration of traditional nomothetic and ideographic approaches, and other life sciences. However, the development of a transdisciplinary line of research requires further inputs from different epistemological views, as well as higher attention to the potential contribution of different philosophical traditions.

The moderating and mediating effects of personality on the association between morningness and well-being

Background

Morningness (morning-eveningness preference or chronotypes) and personality can be both associated with well-being, but few studies have directly compared these two constructs as correlates of well-being. Thus, the first purpose of this study was to test the effects of interactions between stable personality traits (temperaments) and morningness on well-being. Furthermore, personality factors are often composed of both stable biological factors (temperament) and socio-cultural factors (character), and little is known about personality interplay of temperament and character factors with respect to morningness and well-being. The second purpose of this study was therefore to examine the sequential mediating effects of temperament and character factors on the relationship between morningness and well-being.

Methods

The Composite Scale of Morningness, the Korean version of the Temperament and Character Inventory-Revised Short Version (TCI-RS), and the Satisfaction with Life Scale were used to measure morningness, personality dimensions, and well-being, respectively, in 287 Korean university students. Moderating and sequentially mediating effects of temperament and character traits were determined using Hayes' PROCESS macro in SPSS after controlling for sex and age.

Results

First, novelty-seeking (NS) and persistence (PS) temperaments have demonstrated the moderating effect in the association between morningness and well-being. The positive effects of morningness on life satisfaction increased with lower NS and PS, respectively. However, other temperaments such as harm avoidance (HA) and reward dependence (RD) have not shown the moderation in the relationship between morningness on well-being. Second, HA temperament and self-directedness (SD) character sequentially mediated the relationship between morningness and well-being. The combination of low scores of HA and high scores of SD have shown the positive effect on the relationship between morningness and well-being.

Discussion

This study demonstrated that both the interactions between temperaments and morningness, and combination of specific TCI-RS temperament and character traits play important roles in influencing the association between morningness and well-being. The significance of the mature SD character and its implications for well-being are discussed with limitation of the present study.

Disentangling the personality pathways to well-being

Recent genomic, psychological, and developmental research shows that human personality is organized as a complex hierarchy that ascends from individual traits in many specific situations to multi-trait profiles in two domains that regulate emotional reactivity (temperament) or goals and values (character), and finally to three integrated temperament-character networks that regulate learning to maintain well-being in changing conditions. We carried out person-centered analyses of the components of subjective well-being (positive affect, negative affect, and life satisfaction) to personality in both adolescents (N = 1739) and adults (N = 897). Personality was considered at each level of its organization (trait, temperament or character profiles, and joint temperament-character networks). We show for the first time that negative affect and life satisfaction are dependent on the personality network for intentional self-control, whereas positive affect is dependent on the personality network for self-awareness that underlies the human capacities for healthy longevity, creativity, and prosocial values.

Psychometric Properties of the Portuguese Adolescent Students’ Basic Psychological Needs at School Scale (ASBPNSS) and Evidence of Differential Associations With Indicators of Subjective Wellbeing

The study aimed to test the psychometric properties of a Portuguese adaptation of the Adolescent Students’ Basic Psychological Needs at School Scale (ASBPNSS). For this, we used data from a sample of eighth graders ( N = 1648; Mage = 14.1 years; 46.9% girls) from Portugal. Cronbach alpha and omega coefficients showed the ASBPNSS subscales—autonomy, relatedness, and competence—were reliable. Confirmatory factor analysis (CFA) showed the hypothesized three-factor model fit the data well. Multi-group CFAs showed the ASBPNSS had scalar invariance across gender and students from different socioeconomic backgrounds. Finally, need satisfaction in school was positively correlated with positive affect and life satisfaction and negatively correlated with negative affect. These findings support the theoretical assumptions of Basic Psychological Needs Theory (BPNT), and particularly the assumption that basic needs are universally applicable. We conclude the ASBPNSS is a reliable and valid measure of basic need satisfaction at school in Portuguese adolescents.

The KIDSCREEN-27 Quality of Life Measure for Romanian Children Aged 6: Reliability and Validity of the Romanian Version

The KIDSCREEN-27 represents a standardized, worldwide instrument, employed to assess the health-related quality of life in children. The purpose of the present study is to validate the KIDSCREEN-27 questionnaire for 6-year-old preparatory school children and verify its reliability, as well as to perform a comparison regarding the quality of children’s lives living in two cities in Romania: Arad, a provincial city, versus the second most developed city in the country, Cluj-Napoca. A total of 256 children of 6 years of age, who come from families with both parents, with a medium to high socioeconomic status and a good health status, were included in the analysis, using the KIDSCREEN-27 questionnaire at three assessment time points with a re-test period of two weeks. Results indicated that the KIDSCREEN-27 turned out to be suitable for use in 6-year-old Romanian children. Analysis regarding the psychometric properties showed that the Cronbach’s alpha ranged from 0.554 to 0.661 at the end of the study. The Pearson correlation coefficients showed statistically significant differences between the items of each area investigated. In conclusion, there is a growing need to periodically monitor the health status of children to avoid possible problems which may occur.

The Quality of Life for Children with Autism Spectrum Disorder Scale: Factor Analysis, MIMIC Modeling, and Cut-Off Score Analysis

Our purpose in this study was to further examine the psychometric properties of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We first investigated the factor structure and the internal consistency of the scale. The bifactor model showed good fit and strong reliability. Second, we used multiple-indicators multiple-causes (MIMIC) modeling to examine the associations between demographic variables and the QOLASD-C dimensions. Results showed differences on overall QOL based on age, race/ethnicity, and autism spectrum disorder severity, but no relationships with gender. All demographic variables were associated with one or all three subscales (i.e., interpersonal relationships, self-determination, emotional well-being) of the QOLASD-C. Third, an optimal cut-off score of 37 was identified. Implications for research and practice are discussed.

Translation and psychometric validation of the Persian version of the Questionnaire on Smoking Urges for assessment of craving to smoke among university students

Background

Even though tobacco is one of the most preventable causes of death worldwide, it endangers more than 8 million people yearly. In this context, meta-analyses suggest that a significant part of the general Iranian population over 15 years of age smoke and that there is a need for good screening tools for smoking cravings and urges in Iran. The present study reported the translation and investigated the psychometric properties (i.e., factor structure, validity, and reliability) of the Persian version of the Questionnaire on Smoking Urges (QSU) with 12 items in the Iranian context.

Method

The translation process and content validity of the items were examined entirely in an expert panel using the Content Validity Index. The total sample of participants in which the translated version was tested consisted of 392 (172 female, 220 male, M_age = 22.31 years, SD = 2.90) university students who answered the QSU 12-item at the start of their participation in smoking cessation interventions. The QSU 12-item was firstly translated, then piloted using a subsample of 150 university students and finally validity and reliability of the instrument were investigated using a subsample of 242 participants. We tested the proposed models in the literature, that is, a 1-factor solution and a 2-factor solution with six items on each factor (Factor 1: desire/intention to smoke; Factor 2: relief of negative affect or withdrawal symptoms and anticipation of positive outcome). At last, we tested differences across differences in QSU-scores across different subgroups of individuals based on their demographics.

Results

The results suggested that, in contrast to past studies, a modified 2-factor model, using five items for Factor 1 and 7 items for Factor 2, was the best fitting model (CFI = .95, RMSEA = .09, CI = 90%). Additionally, the QSU 12-item Persian version showed good convergent and divergent validity, internal consistency (Factor 1 = .94, Factor 2 = .97), ICC (average measure ICC = .95, CI = 95%, F_{(391, 4301)} = 20.54, p < .001), concurrent validity (r = .71, p < .01), and discriminant validity (r = −.04, p > .05). Finally, subgroups based on gender, marital status, (un)employment, and educational level did not differed in their responses to the QSU 12-item.

Conclusion

The Persian version of the QSU 12-item has satisfactory psychometric properties and, with a slight modification, it can be considered as a reliable and valid method to estimate smoking urges in the Iranian population. Moreover, the QSU 12-item seems appropriate to measure urge for smoking among groups of individuals with different sociodemographic backgrounds. Importantly, the QSU 12-item differentiates individuals’ desire and intention to smoke from their anticipated relief of negative affect or withdrawal symptoms, which can be important for personalizing interventions targeting individuals who want to quit smoking.

Healthy Behavior as a Mediator in the Relationship Between Optimism and Life Satisfaction in Health Sciences Students: A Cross-Sectional Study

Purpose

This study examines the indirect relationship between optimism and life satisfaction via healthy behavior among health sciences students.

Participants and Methods

The cross-sectional study involved 349 health sciences students, including 58% of women, ranging in age between 19 and 30 years (M = 22.15, SD = 1.83). Self-report questionnaires were used to measure dispositional optimism (the Life Orientation Test-Revised, LOT-R), life satisfaction (Satisfaction with Life Scale, SWLS), and health behaviors (Health Behavior Inventory, HBI), with four subscales: healthy diet (HD), preventive behavior (PB), positive mental attitudes (PMA), and healthy practices (HP). In addition, a single mediation model (with the total HBI as mediator) was compared with a parallel mediation model (with four subscales of the HBI). Gender was controlled as a confounding variable.

Results

Women scored higher in the total HBI (p < 0.01), HD (p < 0.001) and PB (p < 0.01) than men, while men scored slightly higher in dispositional optimism (p < 0.01). General health behavior (total HBI) completely mediates the relationship between dispositional optimism and life satisfaction, R² = 0.32. In the parallel model, only PMA was determined as a mediator of the association between dispositional optimism and satisfaction with life, R² = 0.36. The single mediation model showed perfect fit (X²/df = 0.00, RMSEA = 0.00, SRMR = 0.00, CFI = 1.00, IFI = 1.00, NFI = 1.00), better than the parallel mediation model (X²/df = 2.353, p = 0.095, RMSEA = 0.062, SRMR = 0.020, CFI = 0.995, IFI = 995, NFI = 991).

Conclusion

The interplay mechanism between personal resources and behavioral health-related habits may explain 32% of life satisfaction variance. The intervention focused on increasing optimistic expectancies and health behaviors should be implemented in universities to increase students’ well-being and prevent depression.

Psychometric properties of the Swedish version of the satisfaction with life scale in a sample of individuals with mental illness

BACKGROUND

Health assessment among individuals with mental health problems often involves measures of ill-being (e.g., anxiety, depression). Health is, however, defined as a state of physical, mental and social well-being and not merely the absence of disease (WHO, 1948, 2001). Hence, in order to address mental illness during the 21st century, we need to develop methods for the prevention, identification and treatment of mental illness; but also, for the promotion, identification, and maintenance of well-being. In this context, over three decades of subjective well-being research have resulted in the development of measures of positive aspects of human life, such as the Satisfaction with Life Scale (Diener et al., 1985). Our aim was to investigate the psychometric properties of the Satisfaction with Life Scale in a Swedish population of individuals with mental illness using both Classical Test Theory (CTT) and Item Response Theory (IRT).

METHOD

A total of 264 participants (age mean = 43.46, SD = 13.31) diagnosed with different types of mental illness answered to the Swedish version of the Satisfaction with Life Scale (five items, 7-point scale: 1 = strongly disagree, 7 = strongly agree).

RESULTS

We found positive and significant relationships between the five items of the scale (r ranging from 0.37 to 0.75), good reliability (Cronbach's alpha = 0.86), and that the one-factor solution had best goodness of fit (loadings between 0.52-0.88, p < 0.001). Additionally, there were no significant differences in comparative fit indexes regarding gender and occupation status. All items had high discrimination values (between 1.95-3.81), but item 5 ("If I could live my life over, I would change almost nothing"); which had a moderate discrimination value (1.17) and the highest estimated difficulty on response 7 (3.06). Moreover, item 2 ("The conditions of my life are excellent") had less discrimination and redundant difficulty with both item 1 ("In most ways my life is close to my ideal"; 2.03) on response 7 and with item 3 ("I am satisfied with my life"; -1.21) on response 1. The five items together provided good information, with especial good reliability and small standard error within -1.00 up to about 2.00 and the highest amount of test information at 0.00 of the level of life satisfaction within this population.

CONCLUSIONS

Consistent with previous research, the scale had good reliability and provided good information across most of the latent trait range. In addition, within this population, sociodemographic factors such as gender and occupation status do not influence how individuals respond to the items in the scale. However, the items couldn't measure extreme levels of low/high life satisfaction. We suggest replication of these findings, the test of additional items, and the modification of items 2 and 5 in order to use the scale among individuals with mental illness.

Psychometric properties of the Multi-group Ethnic Identity Measure (MEIM) in a sample of Iranian young adults

BACKGROUND

This study examines the factor structure, reliability and test-retest validity of the 12-item Iranian version of the Multigroup Ethnic Identity Measure (MEIM). Additionally, the MEIM's concurrent validity was tested by investigating the association between ethnic identity and subjective well-being.

METHOD

The scale was translated into Persian language and was administered to 426 students (193 female) at a major public university in Tehran along with the Positive Affect Negative Affect Schedule, and the Satisfaction with Life Scale.

RESULTS

The confirmatory factor analysis supported the two-factor first-order commitment, and exploration (consisting of 12 items), and the second-order unidimensional factor structure of general ethnic identity. Moreover, we found evidence for good internal consistency, test re-test reliability, and concurrent validity.

CONCLUSION

The MEIM Persian version was found to be a valid and reliable measure to examine ethnic identity in this Iranian student population, for both males and females. These results support the utility of the Persian version of the MEIM for its use in Middle-Eastern contexts.

School health assessment tools: a systematic review of measurement in primary schools

Background

This systematic review aimed to investigate the psychometric properties of the school health’s assessment tools in primary schools through COSMIN Risk of Bias checklist. We examined the studies that have addressed the measurement properties of school-health instruments to give a clear overview of the quality of all available tools measuring school health in primary schools. This systematic review was registered in PROPERO with the Registration ID: CRD42020158158.

Method

Databases of EBSCOhost, PubMed, ProQuest, Wily, PROSPERO, and OpenGrey were systematically searched without any time limitation to find all full-text English journal articles studied at least one of the COSMIN checklist measurement properties of a school-health assessment tool in primary schools. The instruments should be constructed based on a school health model. The eligible studies were assessed by COSMIN Risk of Bias checklist to report their quality of methodology for each measurement property and for the whole study by rating high, moderate or low quality.

Results

At the final screening just seven studies remained for review. Four studies were tool development, three of them were rated as “adequate” and the other study as “very good”; five studies examined the content validity, three of them were appraised as “very good”, and the two remaining as “inadequate”. All seven studies measured structural validity, three of them were evaluated as “very good”, three other were scored as “adequate”, and the last study as “inadequate”. All the seven studies investigated the internal consistency, five of them were assessed as “very good”, one was rated as “doubtful”, and the last one as “inadequate”. Just one study examined the cross-cultural validity and was rated as “adequate”. Finally, all seven studies measured reliability, two of them were rated as “very good” and the rest five studies were appraised as “doubtful”. All rating was based on COSMIN checklist criteria for quality of measurement properties assessment.

Conclusion

The number of studies addressing school health assessment tools was very low and therefore not sufficient. Hence, there is a serious need to investigate the psychometric properties of the available instruments measuring school health at primary schools. Moreover, the studies included in the present systematic review did not fulfill all the criteria of the COSMIN checklist for assessing measurement properties. We suggest that future studies consider these criteria for measuring psychometric properties and developing school health assessment tools.
