Validation of psychosocial scales for physical activity in university students

Abstract

OBJECTIVE Translate the Patient-centered Assessment and Counseling for Exercise questionnaire, adapt it cross-culturally and identify the psychometric properties of the psychosocial scales for physical activity in young university students.METHODS The Patient-centered Assessment and Counseling for Exercise questionnaire is made up of 39 items divided into constructs based on the social cognitive theory and the transtheoretical model. The analyzed constructs were, as follows: behavior change strategy (15 items), decision-making process (10), self-efficacy (6), support from family (4), and support from friends (4). The validation procedures were conceptual, semantic, operational, and functional equivalences, in addition to the equivalence of the items and of measurements. The conceptual, of items and semantic equivalences were performed by a specialized committee. During measurement equivalence, the instrument was applied to 717 university students. Exploratory factor analysis was used to verify the loading of each item, explained variance and internal consistency of the constructs. Reproducibility was measured by means of intraclass correlation coefficient.RESULTS The two translations were equivalent and back-translation was similar to the original version, with few adaptations. The layout, presentation order of the constructs and items from the original version were kept in the same form as the original instrument. The sample size was adequate and was evaluated by the Kaiser-Meyer-Olkin test, with values between 0.72 and 0.91. The correlation matrix of the items presented r < 0.8 (p < 0.05). The factor loadings of the items from all the constructs were satisfactory (> 0.40), varying between 0.43 and 0.80, which explained between 45.4% and 59.0% of the variance. Internal consistency was satisfactory (α ≥ 0.70), with support from friends being 0.70 and 0.92 for self-efficacy. Most items (74.3%) presented values above 0.70 for the reproducibility test.CONCLUSIONS The validation process steps were considered satisfactory and adequate for applying to the population.

Development and validation of a questionnaire to evaluate infection control in oral radiology

“…The questionnaire produced stable answers when applied at different times, 15,17,21,24,32,33 a finding which reflects the questions' high level of comprehension. 19 Internal consistency was very good, 15,18,19,24,27,32,34 a finding which indicates correlation between all of the items. 21,31 Owing to the lack of a questionnaire on infection control in oral radiology that could be considered the gold standard with which this new questionnaire could be compared, the validity of the criteria cannot be analyzed.…”

“…14,17,18 Reliability was determined using test-retest and internal consistency. 13,15,17,19,24,25,31,32 In this stage, the questionnaire was applied and reapplied to the 115 students at 2 different times, with a 1-week interval between them. 33,34 To determine intraevaluator reproducibility, the ordinal variables were analyzed using the intraclass correlation coefficient (ICC) with a cut-off value .0.70, 17,18,21,31 and kappa was used for the yes/no questions with a cut-off value .0.60.…”

“…17,33 To determine internal consistency, Cronbach's alpha was used with a cut-off value .0.70. 15,18,19,24,27,32,34 The construct validity of the questionnaire was determined using factor analysis and the knowngroups technique. 17,21 In this case, the questionnaire was also applied to professors of oral radiology and PhD students in oral radiology in addition to the 641 dentistry students, which allowed for a comparison between the scores of these group answers.…”

“…Pre- and post-surveys were self-reported and were developed using a responsive web design, optimized to work well in various devices and screen sizes. Mothers self-reported on child nutrition in terms of child food neophobia, 18 child sleep behaviors, 19 nurturing care (mother–child interactions and early learning opportunities), 20 maternal psychosocial well-being, 21 parental self-efficacy, 22 and maternal social support 23 using validated questionnaires described in the Supplemental Material 1 .…”

Coach-Athletes Communication: Data from the Communication Behaviors Evaluation System

“…respondida através de uma escala Likert de cinco pontos (não gosto muito = 1 e gosto muito = 5). A avaliação da autoeficácia para AF foi realizada através da versão validada para o contexto brasileiro do Patient-Centered Assessment and Counseling for Exercise (PACE) (Tassitano et al, 2015). Utilizou-se seis itens que verificavam o nível de confiança dos adolescentes em serem fisicamente ativos em determinadas situações.…”
