  • Analysis of Exercise Intensity Preferences, Tolerance, Competence, and Their Implications for Behavioral Intentions in Fitness Settings
    Publication . Rodrigues, Filipe; Jacinto, Miguel; Antunes, Raul; Amaro, Nuno; Matos, Rui; Monteiro, Diogo
    This study aims to comprehensively investigate the interrelationships among exercise intensity preference, tolerance, competence satisfaction, competence frustration, and exercise intentions within the fitness domain. The research involved 114 participants aged 18 to 59 years (M = 33.23; SD = 10.542), with an average height of 166.02 cm (SD = 15.856) and weight of 68.02 kg (SD = 13.658). The path analysis revealed positive correlations among constructs, except for the link between exercise intensity tolerance and competence satisfaction. Notably, exercise intensity preference positively related to competence satisfaction (β = 0.20, CI90% = 0.12, 0.40), while both preference and tolerance were negatively linked to competence frustration (preference: β = −0.27, CI90% = −0.44, 0.03; tolerance: β = −0.17, CI90% = −0.03, 0.24). Competence satisfaction (β = 0.37, CI90% = 0.13, 0.34) and competence frustration (β = −0.29, CI90% = −0.48, −0.09) significantly influenced exercise intentions. An indirect effect existed between exercise intensity preference and intentions (β = 0.11, CI90% = 0.03, 0.21), contrasting with the lack of such effect for intensity tolerance (β = 0.05, CI90% = −0.01, 0.14). Intentions explained 16% of the variance. In conclusion, this study underscores the intricate connections between exercise intensity traits and intentions, shedding light on factors influencing individuals’ exercise persistence.

  • Psychometric Properties of Different Versions of the Body Shape Questionnaire in Female Aesthetic Patients
    Publication . Fernandes, HM; Soler, Patrícia; Monteiro, Diogo; Cid, Luis; Novaes, Jefferson
    The purpose of this study was to examine and compare the psychometric properties (internal consistency and factorial validity) of different versions of the Body Shape Questionnaire (BSQ) in a sample of female aesthetic patients. The sample included 296 women attending aesthetic clinics, with ages ranging between 18 and 70 years (M = 32.23, SD = 11.35) and body mass index between 17.10 and 45.00 kg/m2 (M = 24.70, SD = 4.07). Nine different length versions of the BSQ (BSQ-34, BSQ-32, BSQ-16A, BSQ-16B, BSQ-14, BSQ-8A, BSQ-8B, BSQ-8C and BSQ-8D) were subjected to confirmatory factor analyses, using a robust maximum likelihood estimator. Robust fit indices indicated that the BSQ-8D version was the better-fitting and more parsimonious model (S-Bχ2/df = 1.81, CFI = 0.963, RMSEA = 0.052, SRMR = 0.043). This short version also showed appropriate reliability (McDonald’s omega and composite reliability = 0.87) and a very high correlation with the original BSQ-34 version (r = 0.95). In sum, these findings suggest that the BSQ-8D is the most valid, reliable and suitable BSQ version for measuring body shape concerns in female aesthetic patients.
