    Introduction: This study was designed to produce a validated and reliable Malay version of the Identification of Functional Ankle Instability (IdFAI-M) questionnaire.

    Materials and method: The cross-cultural adaptation was conducted based on standard guidelines to produce the Malay version of the Identification of Functional Ankle Instability (IdFAI-M) questionnaire. The reliability and validity testing were then performed among one hundred and twenty-three physically active University of Malaya students. Among them, twenty-two students also participated in the second return of the questionnaire over a two-week interval, which was then evaluated for test-retest reliability testing.

    Results: The content validity for item-level (I-CVI) and Kappa values for all items were more than 0.7, respectively and the all scales-level (S-CVI) values were 0.983 (consistency), 0.967 (representativeness), 1.00 (relevance) and 0.983 (clarity). The questionnaire also demonstrated excellent reliability with an intraclass correlation coefficient (ICC2.1) above 0.850 for all items. It was observed that outer loading of most items were more than the minimum acceptable value (0.7). Fornell-Larcker criterion demonstrate all values for each reflective construct was larger than the correlations with other constructs, indicating discriminant. The cross-loading values of each item has shown a weak correlation with all other constructs, except for the one to which it was theoretically associated.

    Conclusions: The Malay version of the IdFAI (IdFAI-M) is a reliable and valid instrument that can be readily utilised to subjectively assess ankle instability.

    BACKGROUND: Self-efficacy and learning motivation are widely recognized as key psychological factors influencing students' engagement and learning outcomes. However, evidence regarding their measurement and relationship among vocational college students remains fragmented.

    PURPOSE: This systematic review synthesizes recent empirical studies on self-efficacy and learning motivation among vocational college students, focusing on research trends, measurement approaches, and reported relationships between the two constructs.

    METHODS: Following PRISMA-informed procedures, studies published in English-language peer-reviewed journals from January 2022 to early August 2026 were identified through five databases (Web of Science, Scopus, APA PsycINFO, PubMed, and ERIC). After screening and eligibility assessment, 12 studies were included for coding and synthesis. Findings were analyzed descriptively and thematically to summarize study characteristics, measurement instruments, and patterns of association.

    RESULTS: The findings showed considerable variation in the measurement of both self-efficacy and learning motivation. Despite this heterogeneity, the included studies generally reported a positive relationship between the two constructs, although the strength and form of the relationship varied across studies and motivational dimensions. Overall, the evidence supports a broadly consistent positive association between self-efficacy and learning motivation among vocational college students, while conceptual and methodological heterogeneity limits direct comparison across studies. Future research should improve construct and measurement consistency and employ longitudinal or experimental designs to clarify the relationship between self-efficacy and learning motivation.

    Flexible, highly conductive, and transparent silver nanowires (AgNWs) have emerged as vital materials for advanced applications in photovoltaics, touch screens, and optoelectronics. However, their practical deployment has been hindered by issues such as poor adhesion to diverse substrates (e.g., glass and plastic) and susceptibility to ambient oxidation. In this study, we present a novel approach to overcome these challenges through the synthesis and performance evaluation of transparent conductive electrodes (TCEs) composed of AgNWs with an adhesive SiO2 protective layer deposited on glass, paper, and plastic substrates. Using a combination of polyol synthesis, RF sputtering, and spray coating techniques, we achieved robust and stable TCEs. The SiO2 coating not only significantly improved resistance to oxidation but also enhanced adhesion, mechanical stability, and durability. SiO2/AgNWs/Glass and SiO2/AgNWs/Plastic electrodes demonstrated high transmittance values of 83.36% and 69.67% at 550 nm, along with low sheet resistance of 48.5 Ω sq-1 and 50.2 Ω sq-1, respectively. This work highlights the ability of the adhesive SiO2 layer to preserve optical and electrical properties while enhancing the substrate adherence and protection against degradation.
