Resumen

[EN]The aim of this study was to translate and adapt the physical activity and leisure motivation scale (PALMS) into Spanish, and to analyse its validity and reliability. The sample comprised 867 adolescents, with a mean age of 14.04 ± 1.19 years, 53.9% of whom were male. During the translation process, some of the items in the instrument were modified slightly, improving its comprehensibility. On the other hand, the exploratory factor analysis did not present an adequate factor structure, so a more in-depth analysis was carried out, using item response theory and confirmatory factor analysis; the conclusion was that it would be appropriate to eliminate several items from the scale. From this, a final shortened version, consisting of 25 items, was produced, with adequate fit indices—CFI = 0.933, TLI = 0.918, SRMR = 0.042, RMSEA = 0.052 (90% CI 0.048; 0.056)—and good reliability for each of the dimensions, ranging from 0.625 to 0.835. It can be concluded that the abbreviated version of the PALMS instrument, adapted for Spanish adolescents (PALMS-e), is a valid and reliable instrument for assessing their motives for doing physical activity

Descripción

METHODOLOGICAL INFORMATION 1. Description of methods used for collection-generation of data: Instrument We used the PALMS instrument, originally developed by Morris and Rogers (2004) [32]. 1. Description of the PALMS. It consists of 40 items, which measure the motives for doing PA and the questions are equally distributed among its 8 factors. The responses are 5-point Likert-type, where 1 corresponds to “strongly disagree” and 5 to “strongly agree”; 2. Factors according to the distribution of the PALMS items. Ego (items 6, 17, 27, 29, and 39), appearance (items 11, 23, 32, 36, and 40), other’s expectations (items 1, 7, 18, 21, and 26), affiliation (items 4, 8, 20, 30, and 38), physical condition (items 10, 12, 15, 28, and 33), psychological condition (items 2, 9, 14, 22, and 35), mastery (items 5, 16, 19, 24, and 31), and fun (items 3, 13, 25, 34, and 37); 3. Reliability of the PALMS. Validations of this scale in adult populations, such as that of Molanorouzi et al. (2014) [37], showed good internal consistency, with a Cronbach’s alpha of 0.82. The same was seen with an earlier version by Zach et al. (2012) [36], which was applied, on this occasion, to a population between 9 and 69 years of age (values between 0.63 and 0.96 for the subscales). Procedure. The process was divided into the following three parts: in the first, the PALMS scale was translated and adapted (n = 14); in the second, the adapted scale was applied to a larger population group (n = 198); and in the third, the validity and reliability of the PALMS scale adapted into Spanish was tested (n = 867), resulting in a proposal for a reduced version of this scale. The translation–adaptation stage was conducted using 14 school students aged between 13 and 16 (8 males, 6 females). The instrument was adapted according to the process of Mungía-izquierdo, Legaz-Arrese and Mannerkorpi (2011) [45], through what is known as a translation back-translation [46,47]. Once the instrument had been translated and culturally adapted by an expert, to confirm the reliability of the test for the selected population, a test–retest was administered to 198 subjects, with a mean age of 14 ± 1.09 years, ranging from 12 to 16 years of age, 56.1% (n = 111) of whom were male. The final questionnaires (n = 867) were administered by the same researcher, within a single 15-min session during the students’ timetabled physical education classes. In all the studies, we had the authorisation of the school and teachers, as well as the written consent of the parents or guardians of the minors involved. Brief instructions were provided and the participants were assured of the confidentiality of their responses. Participation was entirely voluntary. The respondents received no academic or monetary compensation for their contribution. No student refused to participate. The research was performed according to the ethical guidelines of the current Declaration of Helsinki (Brazil, 2013), complying at all times with the highest standards of safety and professional ethics for this type of work. Data Analysis. An exploratory factor analysis (EFA) was run to study the construct validity of the research. Next, since the results did not replicate the factorial structure, the information function was studied using item response theory (IRT) and various reliability indices to assess the quality and relevance of the items in the different dimensions. Finally, once the problematic items had been eliminated, a confirmatory factor analysis (CFA) was performed to check the goodness of fit of the final data to the theoretical model proposed by the authors. Analyses were performed using Jamovi software, version 1.6.15.
