Abstract
Introduction: motivation is an inner psychological driving force that persuades child to take efforts to master activities or skills that are somewhat challenging, The aim of this study was to investigate the psychometric properties of the Iranian version of the Mastery Motivation Questionnaire(DMQ18) in children aged 6-23 months.
Method: this research is a descriptive – survey method, which in 1047 children aged 6 to 23 months, recruited randomly from shiraz that rating by the parent in mastery motivational Dimensions of Mastery Questionnaire (DMQ-18). it has 39 items, with seven subscales in the 5 Likert range were used to quantify it. Psychometric of Questionnaire used by content validity (expert opinions) and construct validity by confirmatory factor analysis; and reliability was evaluated through Cronbach’s alpha. KMO index for sampling adequacy and Bartlett test for sphericity of the studied questionnaire data are in good condition, Kaiser-Meyer-Ulkin index (KMO) is equal to 0.89, and Bartlett index is significant at the level of 0.001.
Result: The results of confirmatory factor analysis show that the questionnaire has good validity and fit and 7 subscales of mastery motivation have the desired factor loads (0.75-0.99), Non-questions excluded from the confirmatory factor analysis, and thus all questions remained. Also, Cronbach's alpha coefficient is 0.95, which indicates that the mastery motivation questionnaire has acceptable reliability. Internal consistency was acceptable in all subscales (more than 0.70) except for the negative reaction (0.60). ) and general competence (0.63).
Conclusion: MQ18 (parental report) was valid and reliable for children 6-23-month-olds, it has robust psychometric properties also specialist and psychologists of child development has scientific and practical uses.

Abstract
Introduction: Investigating the factors affecting motor development is very important in identifying the causes of motor developmental delay for parents and occupational therapists in the development of pediatric treatment. This study aims to model dynamic factors affecting fine motor development milestones of 9-12 months old infants.
Method: in this study 283 children were screened by age and stage scale which included providing the home environment for motor development-infant scale, parental postpartum attachment scale, Beak habitual physical activity questionnaire, and general health questioner. Factors affecting motor development were classified into three parts: individual, maternal and environmental factors.
Result: Structural equation model showed that according to the fitting indexes reported, the conceptual model of this research does not have an acceptable fitting level. Regression results showed that none of the factors had a significant contribution to the prediction of fine movements in the maternal factors group. Linear regression in the individual factors group showed that age with an effective coefficient of -0.15 and motivation with an effective coefficient of 0.14 had a significant contribution to the prediction of fine movements. And in the environmental factor group, the number of siblings with an effective coefficient of -0.17 and parents' encouragement with an effective coefficient of 0.15 had a significant contribution to the prediction of fine movements.
Conclusion: The present results showed that the present predictive variables had poor predictive power, so more research is needed to identify stronger predictors of fine motor development.
