RESUMO

Objective: This paper illustrates the preliminary psychometric properties of the Questionnaire for Adaptive Hyperactivity and Goal Achievement (AHGA), aimed at measuring adaptive characteristics of hyperactivity and goal pursuit in older adults. Methods: The 12-item scale was administered to a sample of 120 subjects (older adults) between February 2022 and June 2022. The reliability of AHGA was measured using Cronbach's alpha, and factor structure was established using parallel analysis (PA) and principal component analysis (PCA). Convergent validity was tested against the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN). Results: All included subjects have an average age of 74.1±5.1 years. AHGA reliability was good (Cronbach's alpha: 0.713 [95%CI: 0.630 to 0.783]). Factor analysis suggested two main components: goal achievement and hyperactivity, which explained 41% of the variance in the data. The results support the convergent validity of the scale: AHGA measures adaptive characteristics of hyperactivity and goal pursuit, in contrast to BRIAN, which measures pathological characteristics. Conclusion: The reported findings represent an innovative approach to hyperthymic features by embracing a broader spectrum concept that conceptualizes the potential transition between pathological and adaptive aspects as a continuum.

RESUMO

There is growing interest in psychological factors maintaining healthy functioning following adverse events. One such variable is a sense of coherence (SOC), an orientation to life comprising manageability, comprehensibility, and meaningfulness. Little research has examined the role of SOC in adjustment to bereavement. The present longitudinal study examined the role of SOC in recovery from loss, in a Danish sample (N = 221) of elderly spousally bereaved people. The aim was twofold. First, we aimed to establish the optimal measurement model of SOC, evaluating the fit of different factor solutions for the 29-item SOC-29 scale and 13-item SOC-13 scale, using confirmatory factor analysis. Second, we sought to examine associations of emerging SOC factors with symptoms levels of prolonged grief disorder (PGD) and depression, and with satisfaction with life, assessed concurrently (at 6 months post-loss) and at two consecutive time points, 13 and 18 months post-loss. Results showed that the three-factor model of the SOC-13 (with distinct manageability, comprehensibility, and meaningfulness factors) provided a good fit to our data. With respect to our second aim, analyses showed that the three SOC factors were associated with concurrently assessed PGD, depression, and satisfaction with life. In the analyses predicting outcomes at Wave 2 and Wave 3, meaningfulness (but not manageability and comprehensibility) predicted some of the outcomes, above and beyond baseline scores of the outcomes. Findings suggest that meaningfulness may increase healthy and attenuate unhealthy responses to loss. Helping bereaved people to experience life's demands as worthy of investment and engagement is likely an important target for bereavement care.

RESUMO

PURPOSE: Long-term weight management requires sustained engagement with energy-balance-related behaviours. According to self-determination theory, behaviour goals can support or undermine motivation depending on the quality of their content (i.e., extrinsic and intrinsic motivation). This study aimed to develop and validate the goal content for weight loss maintenance scale (GCWMS). METHODS: The GCWMS was administered to 1511 participants who had achieved clinically significant weight losses and were taking part in a large weight loss maintenance study: the NoHoW Trial (ISRCTN88405328). The scale derived from two well-established questionnaires regarding exercise goals. Construct validity was examined for 4 theory-driven domains: Health Management, Challenge, Image, and Social Recognition. Split-sample confirmatory factor analysis was conducted to test the factorial validity and multi-group measurement invariance (configural, metric, scalar, and residual invariance). The reliability estimates were also assessed, and discriminant validity was evaluated using 2 conceptually related questionnaires. RESULTS: The first analysis showed a poor fit of the original factorial structure. Subsequent investigation with a new specified model indicated close fit to the data after removal of 3 items χ2(58) = 599.982; p < .001; χ2/df = 10.345; CFI = 0.940; GFI = 0.941; SRMR = 0.063; RMSEA = 0.079 (LL = 0.073; UL = .084). Good internal consistency was achieved in all subscales (α > .775), convergent and divergent validity were verified through associations with other theoretical related constructs. Findings from multi-group invariance test demonstrated that the specified model of GCWMS achieved full measurement invariance for gender but did not support residual invariance across countries. CONCLUSION: Findings support the hypothesised four-dimension structure of the GCWMS, confirming reliability and multi-group invariance in factor structure. Analysis also supports valid group means comparisons on latent factors at gender and at cross-cultural level. Ways to improve the quality of the scale are discussed. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive.

RESUMO

Cross-validation is a useful strategy to address problems associated with the post hoc model fitting. The aim of this study was to cross-validate the BAS-2, in two samples (Calibration and Validation Samples), using an invariance testing strategy. 1127 Mexican adolescents (508 males and 619 females), aged 11-19 years (M = 15.41, SD = 2.30), allocated in two samples (n1 = 672; n2 = 455) completed the Mexican version of the BAS-2, along with other body image-related instruments. The cross-validation supported the generalizability of the one-factor respecified model of the BAS-2. The measure was invariant across body mass index and age, but not across sex. Internal consistency and test-retest reliability (a three-week period between each test) was excellent. In support of the validity of the BAS-2, it was positively associated with scores on body esteem, but negatively with body mass index, drive for thinness, and body dissatisfaction. Normal-weight and young adolescents groups showed higher body appreciation than excess-weight and late adolescents groups, respectively. Considering these findings, it is reasonable to conclude that the BAS-2 is a reliable and valid instrument to assess body appreciation in Mexican adolescents. LEVEL OF EVIDENCE: Level V, cross-sectional, descriptive study.

RESUMO

The study aimed to test the validity of the burnout subtypes hierarchic model operationalized by the 'Burnout Clinical Subtypes Questionnaire' (BCSQ-36) and its applicability in other cultures. To that aim psychometric properties, factorial and convergent validity regarding the Maslach Burnout Inventory - General Survey (MBI-GS), and correlation with demographic factors were reviewed. A voluntary internet-based approach was used on a multi-occupational sample of adult Latvians (n = 394). The results of the internal consistency of the Latvian version of the BCSQ-36 exceeded .89 for all three subtypes. The CFA was used to test a hierarchical factorial model, and the analysis revealed an acceptable fit of the model to the data. Correlation analysis showed results as expected, similarly to the original sample - Underchallenged and Worn-out subtypes correlated with all MBI-GS scales, while Frenetic subtype did not correlate with the MBI-GS Cynicism scale. Besides, demographic data showed some correlation only on the subscale level. Overall research results provide support of the validity of the burnout subtypes hierarchical model and applicability in another culture.

RESUMO

BACKGROUND: The Mood Disorder Questionnaire (MDQ) is a frequently used screening tool for the early detection of Bipolar Disorder (BD), which is often unrecognized or misdiagnosed at its onset. In this study, data from Tunisia has been used to evaluate the psychometric properties of the Arabic MDQ. METHODS: The sample included 151 patients with a current major depressive episode. The Arabic adapted version of the Structured Clinical Interview for DSM-IV-TR was used to formulate a diagnosis, yielding 62 patients with BD and 89 with unipolar Major Depressive Disorder (MDD). Principal component analysis with parallel analysis was used to establish the spontaneous distribution of the 13 core items of the MDQ. Confirmatory Factor Analysis (CFA) was used to check the available factor models. Receiver Operating Characteristic (ROC) analysis was used to assess the capacity of the MDQ to distinguish patients with BD from those with MDD. RESULTS: Cronbach's α in the sample was 0.80 (95%CI: 0.75 to 0.85). Ordinal α was 0.88. Parallel analysis suggested two main components, which explained 59% of variance in the data. CFA found a good fit for the existing unidimensional, the two-factor, and the three-factor models. ROC analysis showed that at a threshold of 7, the MDQ was able to distinguish patients with BD from those with MDD with extraordinary negative predictive value (0.92) and a positive diagnostic likelihood ratio of 3.8. CONCLUSION: The Arabic version of the MDQ showed good measurement properties in terms of reliability, factorial validity and discriminative properties.

RESUMO

OBJECTIVE: The negative symptom domain remains a major challenge concerning treatment. A valid self-report measure could assist clinicians and researchers in identifying patients with a relevant subjective burden. The Motivation and Pleasure - Self Report (MAP-SR) derives from the CAINS and is supposed to reflect the "amotivation" factor of negative symptoms. We evaluated different aspects of the scale's reliability and validity. This is the first factorial analysis as well as the first analysis of test-retest reliability. METHODS: We assessed three samples of subjects with schizophrenia or schizoaffective disorder (n = 93) and a broad spectrum of related domains. RESULTS: We explored a 3-, 2- and 1-factor solution (explaining 50.93, 44.85 and 36.18% of variance, respectively). The factor "pleasure and hedonic activity" consists of eight items and was most robust; the factors "social motivation" and "motivation for work" were problematic. Test-retest reliability of the scale was adequate (rS = 0.63, p = .005). Neither the MAP-SR nor the "pleasure and hedonic activities" factor are associated with the PANSS negative symptom scale. There are significant associations with the observer-rated CAINS-MAP scale, experiences of pleasure, and social cognition but none with functional outcome. Discriminant validity could not be established with regards to depression and extrapyramidal symptoms. CONCLUSIONS: We found that the MAP-SR is adequate to assess anhedonia but is less suitable when assessing motivation. Therefore, we propose using the "pleasure and hedonic activity scale" to cover the "anhedonia" subdomain. We think the "motivation" part of the instrument requires reconstruction.

RESUMO

BACKGROUND: Oral health related quality of life (OHRQoL) research among children and adolescents in Lithuania is just starting and no measures have been validated to date. Therefore, this study aimed to validate a Lithuanian version of the full (37 items) Child Perceptions Questionnaire (CPQ11-14) within a random sample of children aged 11 to 14. METHODS: A cross-sectional survey among a randomly selected sample of schoolchildren (N = 307) aged 11 to14 was conducted. An anonymous questionnaire included the full CPQ11-14 and items on global life satisfaction, oral health and oral life quality self-rating. The questionnaire was translated into Lithuanian using translation guidelines. In addition, an item on the oral pain was modified identifying the pain location. Standard tests (Cronbach's α, construct validity and discriminant validity), supplemented with both exploratory and confirmatory factor analyses, were employed for psychometric evaluation of the instrument. The questionnaire was also tested by comparison students' and their parents' (N = 255) responses about oral symptoms and functional limitations. RESULTS: The modified Lithuanian version of CPQ11-14 revealed good internal consistency reliability (Cronbach's alpha for the total scale was 0.88). The measure showed significant associations with perceived oral health status and oral well-being, as well as with global life satisfaction (p < 0.01). Discriminant validity of the instrument was approved by comparison of children's groups defined by self-reported caries experience and malocclusion. Factor analysis revealed a complex structure with two or three factors in each of four domains of the CPQ11-14. Excellent or acceptable levels of indices of model fitting with the given data were obtained for oral symptoms, functional limitations and emotional well-being domains, but not for the social well-being domain. A significant association between child and parental responses was found (intraclass correlation coefficient was 0.56 and 0.43, correspondingly in domains of oral symptoms and functional limitations). CONCLUSION: The Lithuanian version of the CPQ11-14 (with a modified item that identifies location of oral pain) appears to be a valid instrument to be used in further studies for measuring OHRQoL among 11 to 14 year old children in Lithuania.

RESUMO

BACKGROUND: Schizotypal traits are considered a phenotypic-indicator of schizotypy, a latent personality organization reflecting a putative liability for psychosis. To date, no previous study has examined the comparability of factorial structures across samples originating from different countries and cultures. The main goal was to evaluate the factorial structure and reliability of the Schizotypal Personality Questionnaire (SPQ) scores by amalgamating data from studies conducted in 12 countries and across 21 sites. METHOD: The overall sample consisted of 27 001 participants (37.5% males, n = 4251 drawn from the general population). The mean age was 22.12 years (s.d. = 6.28, range 16-55 years). The SPQ was used. Confirmatory factor analysis (CFA) and Multilevel CFA (ML-CFA) were used to evaluate the factor structure underlying the SPQ scores. RESULTS: At the SPQ item level, the nine factor and second-order factor models showed adequate goodness-of-fit. At the SPQ subscale level, three- and four-factor models displayed better goodness-of-fit indices than other CFA models. ML-CFA showed that the intraclass correlation coefficients values were lower than 0.106. The three-factor model showed adequate goodness of fit indices in multilevel analysis. The ordinal α coefficients were high, ranging from 0.73 to 0.94 across individual samples, and from 0.84 to 0.91 for the combined sample. CONCLUSIONS: The results are consistent with the conceptual notion that schizotypal personality is a multifaceted construct and support the validity and utility of SPQ in cross-cultural research. We discuss theoretical and clinical implications of our results for diagnostic systems, psychosis models and cross-national mental health strategies.

RESUMO

AIM: The aim of this study was to investigate the psychometric properties of the Norwegian version of the work-related sense of coherence scale, which measures the perceived comprehensibility, manageability, and meaningfulness of an individual's current work situation. METHODS: Factorial validity, convergent and discriminant validity of the factors, as well as scale reliability were tested with confirmatory factor analyses among two samples of employees in higher education institutions ( N = 6951) and nursing homes ( N = 558). Factorial invariance across occupational groups was also investigated. RESULTS: A modified three-factor structure was shown to be valid and reliable in both samples and invariant across occupational groups. However, problems were detected regarding the discriminant validity between the factors comprehensibility and manageability. CONCLUSIONS: The Norwegian version of the work-related sense of coherence scale seems to have good properties. Further development is needed to better distinguish between the comprehensibility and manageability dimensions.

RESUMO

BACKGROUND: We developed and validated an instrument to measure community-level social capital based on data derived from older community dwellers in Japan. METHODS: We used cross-sectional data from the Japan Gerontological Evaluation Study, a nationwide survey involving 123,760 functionally independent older people nested within 702 communities (i.e., school districts). We conducted exploratory and confirmatory factor analyses on survey items to determine the items in a multi-dimensional scale to measure community social capital. Internal consistency was checked with Cronbach's alpha. Convergent construct validity was assessed via correlating the scale with health outcomes. RESULTS: From 53 candidate variables, 11 community-level variables were extracted: participation in volunteer groups, sports groups, hobby activities, study or cultural groups, and activities for teaching specific skills; trust, norms of reciprocity, and attachment to one's community; received emotional support; provided emotional support; and received instrumental support. Using factor analysis, these variables were determined to belong to three sub-scales: civic participation (eigenvalue = 3.317, α = 0.797), social cohesion (eigenvalue = 2.633, α = 0.853), and reciprocity (eigenvalue = 1.424, α = 0.732). Confirmatory factor analysis indicated the goodness of fit of this model. Multilevel Poisson regression analysis revealed that civic participation score was robustly associated with individual subjective health (Self-Rated Health: prevalence ratio [PR] 0.96; 95% confidence interval [CI], 0.94-0.98; Geriatric Depression Scale [GDS]: PR 0.95; 95% CI, 0.93-0.97). Reciprocity score was also associated with individual GDS (PR 0.98; 95% CI, 0.96-1.00). Social cohesion score was not consistently associated with individual health indicators. CONCLUSIONS: Our scale for measuring social capital at the community level might be useful for future studies of older community dwellers.

RESUMO

BACKGROUND: Restoring sleep is associated with a broad variety of favorable cognitive, emotional, social and behavioral benefits during the day. This holds particularly true for adolescents, as maturational, social, cognitive, emotional and behavioral changes might unfavorably impact on adolescents' sleep. Among adolescents, poor sleep hygiene practices are a potentially modifiable risk factor that can be addressed via appropriate interventions. Accordingly, having reliable and valid self-report measures to assess sleep hygiene practices is essential to gauge individual responses to behavioral interventions and evaluate sleep hygiene recommendations. The aim of the present study therefore was to translate and to test the psychometric properties (internal consistency, test-retest reliability, factorial and concurrent validity) of the Farsi/Persian version of the revised version of the Adolescent Sleep Hygiene Scale (ASHSr). METHOD: A total of 1013 adolescents (mean age: M = 15.4 years; SD = 1.2; range: 12-19 years; 42.9% females) completed the ASHSr and the Pittsburgh Sleep Quality Index (PSQI) in their classroom during an official school lesson. Further, 20% completed the ASHSr 6 weeks later to evaluate the test-retest reliability. Cronbach's alpha coefficients were calculated to examine internal consistency, confirmatory factor analysis (CFA) was used to test factorial validity, whereas concurrent validity and test-retest reliability were examined via correlation analyses. RESULTS: A first-order confirmatory factor analysis (CFA) corroborated the six-factor structure of the ASHSr, including a physiological, behavioral arousal, cognitive/emotional, daytime sleep, sleep environment, and sleep stability factor. A second-order CFA showed that a higher-order sleep hygiene construct explained sufficient variance in each factor. Cronbach's alpha values ranged between .71 and .75, correlations for test-retest reliability between .82 and .87. Significant correlations were found between most ASHSr scales and the PSQI indices. However, the magnitude of these correlations was weak. CONCLUSIONS: The Farsi/Persian version of the Adolescent Sleep Hygiene Scale can be used as a reliable and valid tool for evaluation of sleep hygiene practices among Farsi/Persian-speaking adolescents.

RESUMO

Research on children's physical self-concept (PSC) is increasingly recognised as an important field of psychology. However, there is a lack of instruments suitable for younger children at elementary school age. In the present study, a short German 21-item Physical Self-Concept-Questionnaire for children (PSCQ-C) was tested measuring seven specific facets of elementary school children's PSC (strength, endurance, speed, flexibility, coordination, physical appearance, global sport competence). A number of 770 elementary school children aged 8-12 years completed the PSCQ-C. Results showed good psychometric properties and high reliabilities of the seven scales. Confirmatory factor analysis revealed that the presumed 7-factor model fitted the data best compared to a global 1- and 2-factor model. Also, full measurement invariance was strongly established. Correlations among the seven scales were mainly moderate. Gender differences were suggestive of developmental trends that are consistent with prior studies. These results provide support that the PSCQ-C is a confidential instrument with sound psychometric properties measuring seven specific facets of elementary school children's PSC.

RESUMO

Previous studies using bivariate or correlational analyses have established a relationship between alcohol use, symptoms of anxiety and depression, and scores on a range of temporal psychology measures. Temporal psychology measures variously assess the cognitive or affective (or in some cases, both) engagement with the past, present, and future. Although developed and validated in adolescents, recent research has suggested that the Time Attitudes Scale is internally consistent and reliable in adults also. The present study is the first to apply a person-centered approach to assessing the relationship between scores on the Time Attitudes Scale and symptoms of anxiety, depression, and alcohol-related problems in adults. Participants were recruited from a University in England. Results support the validity and internal consistency of the Time Attitudes Scale. Meaningful time attitudes profiles emerged, however, taking the sample size into account, the only substantive finding showed that those with a negative time attitudes profile scored higher on depressive symptomatology than those with a positive profile. While elsewhere, Zimbardo Time Perspective Inventory scores have been shown to be meaningfully related to anxiety, depression and alcohol use, the present study questions the degree to which the affective dimension of temporal psychology is driving that relationship.

RESUMO

OBJECTIVES: To evaluate the reliability and factorial validity of the four-item Morisky Green Levine Medication Adherence Scale (MGLS) among Atherosclerosis Risk in Communities (ARIC) Study participants. METHODS: We used the cross-sectional visit 5 data from the ARIC Study to assess the measurement properties of the MGLS. We measured the internal consistency using Cronbach α (where α > 0.70 is considered reliable for group-level measurement), the response frequency, and the inter item correlation. Factor analysis of the MGLS and five other adherence items in the survey was conducted using a polychoric correlation matrix to examine the dimensionality that underlies the MGLS. A vanishing tetrad test was conducted to assess conformity with an effect indicator model. RESULTS: Among the ARIC visit 5 participants, 6,261 (96%) responded to the MGLS and other questions related to medication adherence in the survey (mean age 76 ± 5 years, 59% women). The Cronbach α for the MGLS was 0.47. The inter-item correlations ranged from 0.11 to 0.26. In the factor analysis of the medication adherence survey questions, a three-factor solution was used. One factor captured the extent of nonadherence, whereas other factors focused on the reasons for nonadherence. The MGLS items spread out across the factors that reflect the extent of as well as the reasons for nonadherence. The results of the vanishing tetrad test indicated that the MGLS consists of items other than effect indicators (P < 0.0001). CONCLUSIONS: The low reliability together with the factor analysis findings imply that the MGLS may reflect causes as well as the extent of medication adherence. The findings suggest that the MGLS, as presently used, lacks consistency in an elderly population.

RESUMO

OBJECTIVE: This study examined the factor structures and reliabilities of the Asthma Control Test (ACT) and the Asthma Control Questionnaire (ACQ-7; ACQ-6) and the correspondence between them in assessing both level and change in asthma control. METHODS: Lung function and questionnaire data for ACT and ACQ were assessed in 113 asthma patients at the beginning (T1) and the end (T2) of inpatient rehabilitation. Confirmatory factor analyses, composite reliability coefficients, Pearson correlations, Cohen's Kappa and positive/negative agreements were computed. RESULTS: Unidimensional factor structure was confirmed for ACT. For ACQ configural invariance (i.e. same factor structure) over time could not be established. Furthermore, in ACQ-7, FEV1 showed no relation to the latent factor. Reliability estimates were 0.86-0.88 (ACT), 0.88-0.92(ACQ-6) and 0.81-0.86 (ACQ-7). Pearson correlations between ACT and ACQ were between 0.75 and 0.90 and tended to be higher at T2. If the aim is to identify patients with either not well-controlled asthma or change in asthma control, concordance was at least moderate (Kappa = 0.52-0.72). Correspondence tended to be lower in identifying patients with well-controlled asthma (Kappa = 0.30-0.79). In some circumstances, ACQ-6 showed higher agreement with ACT than did ACQ-7. CONCLUSIONS: ACT is a unidimensional measure, but factor structure of ACQ remains unclear. Correspondence between ACT and ACQ depends on the aim of the assessment. Including FEV1 in the assessment of asthma control level even lowers reliability of ACQ and concordance with ACT. Our results support GINA (2014) in conceptualizing FEV1 as a risk factor for poor asthma outcome instead of an indicator of level of asthma control.

RESUMO

Background: The maintenance and promotion of Quality of Life (QoL) of people with dementia is a major outcome in intervention studies and health care. The Quality of Life Alzheimer's Disease (QoL-AD) is an internationally recommended QoL measurement also available in German language. Until now, only a few results on the psychometric properties of the German QoL-AD were available. Objective: Evaluation of internal consistency and construct validity of the QoL-AD proxy. Method: A principal component analysis (secondary data analysis) of the 13 QoL-AD items was carried out based on the total sample of 234 people with dementia from nine nursing homes in Germany. Subsequently, the internal consistency of the identified factors was examined using Cronbach's alpha. Results: Two factors physical and mental health and social network were determined. Both factors explain 53 % of the total variance. The stability of both factors was validated in two sensitivity analyses. The internal consistency is good for both factors with a Cronbach's alpha of 0.88 (physical and mental health) and 0.75 (social network). Conclusion: The QoL-AD proxy allows the assessment of two relevant health-related QoL domains of people with dementia. However, in future studies especially the inter-rater reliability of the QoL-AD proxy has to be examined.

RESUMO

AIM: Disgust is one of the principal emotions, typically triggered by a variety of biological and social stimuli. Several questionnaire tools have been used to assess disgust. The aim of the study was to assess psychometric properties of the Polish version of the Questionnaire for the Assessment of Disgust Sensitivity (QADS), adapted from the tool prepared by the German researchers. METHODS: Eight hundred twenty subjects (631, 77% females and 189, 23% males) aged 18-69 (mean - 28 years) participated in the study. There are 3 subscale in the questionnaire: Core Disgust, Animal Reminder and Contamination. The tool consists of 37 items, the intensity of feeling of disgust is assessed based on 5-point Likert scale. RESULTS: Confirmatory factor analysis confirmed the adequacy of grouping of items in the three subscales: Core Disgust, Animal-Reminder, and Contamination-Interpersonal. In our sample, females had higher levels of disgust than males. Several other psychometric variables - high degree of correlations between the subscales, and high reliability -were in agreement with parameters of the original version. The Polish version compared favourably with the original, with Cronbach's alpha of 0.94 for the whole questionnaire and 0.85 - 0.90 for the subscales. CONCLUSIONS: The psychometric properties of the Polish version of QADS are sufficient to recommend this tool for diagnostic and research use.

RESUMO

Building on the work of Terry and colleagues (Terry, P. C., Lane, A. M., Lane, H. J., & Keohane, L. (1999). Development and validation of a mood measure for adolescents. Journal of Sports Sciences, 17, 861-872; Terry, P. C., Lane, A. M., & Fogarty, G. J. (2003). Construct validity of the Profile of Mood States-Adolescents for use with adults. Psychology of Sport & Exercise, 4, 125-139.), the present study examined the validity and internal consistency reliability of the Chinese version of the Brunel Mood Scale (BRUMS-C) among 2,548 participants, comprising adolescent athletes (n = 520), adult athletes (n = 434), adolescent students (n = 673), and adult students (n = 921). Both adolescent and adult athletes completed the BRUMS-C before, during, or after regular training and both adolescent and adult students completed the BRUMS-C in a classroom setting. Confirmatory factor analyses (CFAs) provided support for the factorial validity of a 23-item six-factor model, with one item removed from the hypothesised measurement model. Internal consistency reliabilities were satisfactory for all subscales across each of the four samples. Criterion validity was supported with strong relationships between the BRUMS-C, abbreviated POMS, and Chinese Affect Scale consistent with theoretical predictions. Multi-sample CFAs showed the BRUMS-C to be invariant at the configural, metric, strong, and structural levels for all samples. Furthermore, latent mean difference analyses showed that athletes reported significantly higher levels of fatigue than students while maintaining almost the same levels of vigour, and adolescent students reported significantly higher levels of depressed mood than the other three samples.

RESUMO

The aim of this study was to investigate the factor structure of a Spanish version of the Sport Motivation Scale adapted to physical education. A second aim was to test which one of three hypothesized models (three, five and seven-factor) provided best model fit. 758 Spanish high school students completed the Sport Motivation Scale adapted for Physical Education and also completed the Learning and Performance Orientation in Physical Education Classes Questionnaire. We examined the factor structure of each model using confirmatory factor analysis and also assessed internal consistency and convergent validity. The results showed that all three models in Spanish produce good indicators of fitness, but we suggest using the seven-factor model (χ(2)/gl = 2.73; ECVI = 1.38) as it produces better values when adapted to physical education, that five-factor model (χ(2)/gl = 2.82; ECVI = 1.44) and three-factor model (χ(2)/gl = 3.02; ECVI = 1.53). Key PointsPhysical education research conducted in Spain has used the version of SMS designed to assess motivation in sport, but validity reliability and validity results in physical education have not been reported.Results of the present study lend support to the factorial validity and internal reliability of three alternative factor structures (3, 5, and 7 factors) of SMS adapted to Physical Education in Spanish.Although all three models in Spanish produce good indicators of fitness, but we suggest using the seven-factor model.
