This study reports psychometric properties and derivation of norms for a Persian version of the Multiple Intelligence Developmental Assessment Scales (MIDAS) for Adults. After examining and confirming equivalency between English and Persian versions, translated and validated by Saeidi, Ostovar, Shearer, and Asghari Jafarabadi (2015), the scale was administered to a sample (N = 2146), including students, undergraduates, graduates, and adults from different provinces in Iran. The participants were at least 19 years old and above (M = 29.40, SD = 2.26). Out of 2146 samples, 1103 females and 1043 were males. To examine the validity and reliability properties of the scale, exploratory and confirmatory factor analyses, Cronbach Alpha (α) reliability correlation coefficients, and corrected item-total correlations were employed. Exploratory factor analysis using varimax rotation identified eight principal components, which accounted for 67.21% of the variance for 115 items. The internal consistency coefficient (α = .92; ranging from 0.89 to 0.93) was also very high. The confirmatory analysis generally replicated the original conceptualization of the MIDAS. According to the results, the Persian-MIDAS-adults questionnaire has good psychometric properties in the research community and can be safely used as a valid tool to assess MI in Iran.

The present exploratory study aimed to provide a more tangible and comprehensive picture of the construct of investment in language learning through investigating the issue from a quantitative perspective. To this end, the present researchers followed three main phases. First, a hypothesized model of investment in language learning with six components was developed for the Iranian English as a foreign language (EFL) learners based on the extensive readings of the literature on investment, consultations with a panel of experts, three university professors in the relevant fields, and interviews with 20 language learners. Second, a questionnaire was developed and validated based on the proposed model to represent its components. Finally, the data collected through this questionnaire were fed into the model to see to what extent the model fitted the data. The participants were male and female English language learners belonging to different age groups and English language proficiency levels.The initial results showed poor values; however, the model was trimmed by removing one item from the questionnaire, and final statistical indices showed that the model fitted the data.
