BACKGROUND: Measurement instruments to understand self-determined motivation towards physical activity among college students with intellectual disabilities are needed to develop programs to support physical and psychological health and well-being. The purpose of the current study was to validate a modified questionnaire measuring basic psychological needs towards physical activity among college students with intellectual disabilities.
METHODS: A total of 108 college students with intellectual disabilities completed the modified questionnaire. Validity and reliability of the questionnaire was examined.
RESULTS: Confirmatory factor analysis demonstrated a six-factor model had good model fit. Cronbach\'s alpha values showed acceptable reliability evidence of the instrument as a whole, although some alpha values in subdomains of the instrument were below acceptable values.
CONCLUSIONS: The modified questionnaire was found to have acceptable validity evidence. Further studies are needed with refinement of answer options and the addition of more questions to increase reliability.

BACKGROUND: The main aim of this study was to assess the validity of the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) and the short version of the Warwick-Edinburgh Mental Well-being Scale (SWEMWBS) and to evaluate the metric properties of both versions by using a sample of undergraduate students from three Gulf Cooperation Council (GCC) countries (Oman, Qatar, and Saudi Arabia).
METHODS: Six hundred ninety undergraduate students (340 M and 350 F; mean age = 21.16 ± 2.44) from Oman, Qatar, and Saudi Arabia (NOM = 238, NQA = 215, NSA = 237), voluntarily participated in this cross-section study. All of them responded to the WEMWBS, Basic Psychological Needs Satisfaction Frustration (BPNSFS), and Beck Depression Inventory (BDI-II). The methodology involved utilizing descriptive statistics to understand the data\'s characteristics, internal consistency analysis for reliability, correlation analysis for convergent validity, confirmatory factor analysis to validate the scales, and measurement invariance testing to ensure cross-group comparability. Model fit indices were employed to gauge the goodness of fit.
RESULTS: The translated Arabic versions of the WEMWBS and SWEMWBS showed good reliability, with Cronbach\'s alpha values of 0.867 and 0.772, respectively. The findings of confirmatory factor analysis asserted the one-factor solution to interpret the item variances of the 14-item WEMWBS and 7-item SWEMWBS. The WEMWBS and SWEMWBS also showed significant positive relationships with need satisfaction and negative relationship with need frustration, and depression. Moreover, the SWEMWBS showed partial scalar invariance across genders and countries, while the WEMWBS showed only partial metric invariance across the three countries and partial scalar invariance across genders.
CONCLUSIONS: Our study highlights the appropriateness of both versions of the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) in assessing the psychological well-being of Arab undergraduate students. The employment of these tools is strongly encouraged for the assessment of mental well-being within a comparable adult population.

Gambling motives are an important element in understanding the development of problem gambling, yet most of the recent studies investigating their role in problem gambling have been cross-sectional. This study analyzed the links between gambling motives and problem gambling using a longitudinal study design. The moderating effect of the frustration of basic psychological needs was also assessed. The study sample with 1,022 participants (48.43% female, Mage = 49.50 years) was surveyed at three timepoints (T1-T3) in 6-month intervals. The Problem Gambling Severity Index (PGSI) was used to measure problem gambling and need frustration was assessed with The Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS). The data were analyzed using a multilevel mixed-effects regression model where PGSI was the outcome variable. Gambling motives and need frustration were the predictors while psychological distress (measured with the 5-Item Mental Health Inventory, MHI-5), offshore/onshore online gambling, and socio-demographic factors were used as control variables. All the motives predicted problem gambling individually over time. In contrast, motives to escape, to win money, and to compete along with need frustration predicted problem gambling over time in the full model. In addition, money motive and need frustration had an interaction effect so that higher need frustration combined with money motive predicted more severe gambling problems. The results of this study provide a valuable longitudinal perspective on gambling motives, frustration of basic psychological needs, and gambling problems which can be used to develop and improve treatment efforts and programs of problem gambling.

The aim of the present study was to adapt and validate the Basic Psychological Need Satisfaction and Frustration Scale within self-determination theory (SDT) within the work domain. Confirmatory factor analyses of three Norwegian samples and one English sample as well as multi-group analyses to examine measurement invariance were performed. The results showed that the adapted work-related scale with its six-factor structure fitted the data well in all four samples, and partial measurement invariance was obtained across samples and languages. Furthermore, internal consistencies for the subscales were acceptable and the subscales predicted work-related correlates as expected, demonstrating the criterion validity of the scale. The current study contributes to a unifying measurement for future research on one of the central underpinnings of SDT within the work domain.

Guided by self-determination theory, the purpose of this study was to gain an understanding of the previous experiences of living with morbid obesity of 10 postbariatric patients enrolled in a physical activity programme. Qualitative data were collected through interviews and diarized observations. A thematic analysis revealed that participants suffered from health and mobility troubles in their daily life and experienced stigmatization and discrimination in most areas of their social functioning. Participants described how these experiences resulted in the thwarting of their basic psychological needs for autonomy, competence and relatedness. In turn, psychological need frustration contributed to negative consequences such as body image concerns, low self-esteem, anxiety and depression; controlled regulation of their eating behaviour and extrinsic goals; rigid behaviours such as avoiding social situations; and compensatory and self-defeating behaviours such as giving up diet and physical activity regimens and binge eating (i.e., oppositional defiance). This study highlights how living with morbid obesity can impair optimal functioning and well-being via experiences of psychological need frustration.
