The purpose of this study was (1) to examine the factorial validity of the Behavioural Regulation Sport in Questionnaire (BRSQ) when completed by young soccer players in the Promoting Adolescent Physical Activity (PAPA) project (9-15 years old) in 5 European countries (France: n = 1248, Greece: n = 1507, Norway: n = 1397, Spain: n = 2245, and England: n = 1372) and (2) test the measurement invariance of its latent factors across these 5 countries. First, we tested the exploratory structural equation model (ESEM) factor analyses, allowing cross-loadings between factors, against the traditional independent clusters confirmatory factor analysis model (ICM-CFA), with all cross-loadings constrained to zero. The ESEM showed very Good Fit Indices, whereas the ICM-CFA was not tenable across countries. Second, the ESEM was used as the baseline model for the tests of factor loading (metric) invariance and factor loading plus thresholds (scalar) invariance. The five factors obtained from the analysis were scalar invariant and interpretable across the five countries (languages) as intrinsic motivation, identified, introjected and external regulations, and amotivation, in line with the tenets of self-determination theory). This study contributes to methodological advances in sport psychology, as it is the first time an adaptation of the BRSQ for young participants has been factor analysed comparing the more flexible ESEM to the usual ICM-CFA. Our data clearly favour using the more flexible weak dimensionality model (ESEM) and suggest a fresh interpretation of previous results may be required.

Purpose: The purpose of the present research was to test how behavioral regulations are mediated between basic psychological needs and psychological well-being and ill-being in a sample of team-sport coaches. Based on self-determination theory, we hypothesized a model where satisfaction and thwarting of the basic psychological needs predicted coaches’ behavioral regulations, which in turn led them to experience well-being (i.e., subjective vitality, positive affect) or ill-being (i.e., perceived stress, negative affect). Method: Three-hundred and two coaches participated in the study (Mage = 25.97 years; 82% male). For each instrument employed, the measurement model with the best psychometric properties was selected from a sequence of nested models sustained by previous research, including exploratory structural equation models and confirmatory factor analysis. These measurement models were included in 3 structural equation models to test for mediation: partial mediation, complete mediation, and absence of mediation. Results: The results provided support for the partial mediation model. Coaches’ motivation mediated the relationships from both relatedness need satisfaction and basic psychological needs thwarting for coaches’ well-being. In contrast, relationships between basic psychological needs satisfaction and thwarting and ill-being were only predicted by direct effects. Conclusion: Our results highlight that 3 conditions seem necessary for coaches to experience psychological well-being in their teams: basic psychological needs satisfaction, especially relatedness; lack of basic psychological needs thwarting; and self-determined motivation.

When assessing team environments in youth sport, participants often spend substantial time responding to lots of items in questionnaires, causing a lack of efficiency (i.e. time and effort) and a decrease of data quality. The purpose of this work was to create short-forms of the questionnaires PeerMCYSQ, SCQPeer, TEOSQ, and also to analyse the existing short-form of the SCQCoach. In Study 1 we developed the short-forms of the instruments. We shortened the questionnaires by using both theory driven and data-driven criteria. In Study 2, we used also qualitative and quantitative data with the aim of validating the short-forms. Finally, in Study 3 we tested the last version of the short-forms and sought evidences concerning their criterion validity. The results showed evidence that supports the psychometric merit of these short-forms: (a) significantly less missing values were obtained; (b) all the factors obtained alpha values above .70; (c) confirmatory factor analyses demonstrated that the short-forms fitted the hypothesized models well; (d) correlations between variables were coherent with expectations, and (e) structural equation modeling results showed significant paths consistent with previous literature. On average, our participants only spent a third of the time used to complete the original questionnaires.

OBJECTIVE In clinical practice, methadone maintenance treatment (MMT) entails tailoring the methadone dose to the patients specific needs, thereby individualizing treatment. The aim of this study was to identify the independent factors that may significantly explain methadone dose adequacy from the patients perspective. METHOD Secondary analysis of data collected in a treatment satisfaction survey carried out among a representative sample of MMT patients (n=122) from the region of La Rioja (Spain). As part of the original study protocol, participants completed a comprehensive battery to assess satisfaction with MMT, psychological distress, opinion of methadone as a medication, participation in dosage decisions, and perception of dose adequacy. RESULTS Multivariate binary logistic regression showed that the only variable independently associated with the likelihood of a patient perceiving methadone dose as inadequate was the variable perceived-participation in methadone dosage decisions (OR=0.538, 95% CI=0.349-0.828). CONCLUSION Patient participation in methadone dosage decisions was predictive of perceived adequacy of methadone dose beyond the contribution of other socio-demographic, clinical, and MMT variables. PRACTICE IMPLICATIONS Patient participation in methadone dosage decision-making is valuable for developing a genuinely patient-centred MMT.

This paper presents the Spanish adaptation of the Automatic Self-Talk Questionnaire for Sports. In the process of adaptation, we preferred cultural and linguistic equivalence to literal translation. Therefore, we gathered qualitative evidence based on the judgements of a multidisciplinary group of experts (n = 6) and focus groups (n = 10). Concerning cultural and linguistic equivalence, we found differences between the original and the adapted version in the editing of 16 items. Generally, these differences were deemed necessary to guarantee the cultural and metric equivalence between the original and the adapted version. As to the subsequent quantitative phase, data were obtained from 263 athletes from different sports and different levels (Mage = 20.30, SD = 3.08). The results showed acceptable levels of internal consistency (α values ranged from .70 to .83) and supported the original model of eight factors. In addition, a structural model including pre-competitive anxiety offered further evidence in regard to the link between self-talk and competitive anxiety. Lastly, some implications concerning the methodology are discussed.

Underpinned by the team cognition perspective, we present the Perception of Distributed Effort in Team Sports Questionnaire (DETSQ). To examine the multidimensional conceptualization of perceived distributed effort in team sports (Beniscelli, Tenenbaum, Schinke, & Torregrosa, 2014), we conducted three studies aimed at developing the DETSQ. In Study 1, we generated items and obtained evidence of content and substantive validity. Consistent with the conceptual framework, we selected the items to reflect three forms of perceived effort: physical, psychological, and tactical. In Study 2, we ran a series of exploratory structural equation models (SEMs)to refine the DETSQ internal structure using the responses from 257 team sport athletes. The result was a 13-item, 3-factor model. In Study 3, we further examined the internal validity of the questionnaire, along with its reliability; measurement invariance across gender, age, and competitive level; and the convergent and consequential aspects of construct validity. The analyses provided evidence to support the psychometric properties of the DETSQ. The discussion focuses on the implication of the DETSQ for processes involving team cognition and suggestions for further research on the perception of distributed effort in team sports.

Purpose The aim of the present study was to test a structural equation model of patient satisfaction with different key facets of methadone maintenance treatment (MMT). In this model, the three dimensions of patient satisfaction with methadone as a medication (ie, personal functioning and well-being, anti-addictive effect on heroin, and anti-addictive effect on non-opioid substances) were expected to predict satisfaction with the basic interventions delivered by the staff of treatment centers to implement MMT. Patients and methods A sample of 210 heroin-dependent patients, resistant to MMT treatment (mean age =41.66 years, SD =6.50; 75.7% male), participated voluntarily in this study. Preliminary analysis based on exploratory structural equation modeling supported the expected three-factor measurement model of the scale to assess satisfaction with medications for addiction treatment – methadone for heroin addiction. Moreover, the 15 items measuring staff’s basic interventions were shown to be compatible with the expected single-factor measurement model. Then, both measurement models were included in a structural model. Results Results of this model show that patient satisfaction with the compatibility of methadone with personal functioning and well-being, as well as with the anti-addictive effects of methadone on non-opioid substances, predicts satisfaction with basic interventions conducted at methadone treatment centers (β=0.191 and β=0.152, respectively). Conclusion Our results provide further understanding regarding patient satisfaction with MMT, which could help professionals to better understand patient perspective and experience during MMT.
