Individualized Behavioral Assessments and Maternal Ratings of Mastery Motivation in Mental Age-Matched Toddlers With and Without Motor Delay

Background

Mastery motivation is a precursor of later developmental outcomes. Evidence about whether toddlers with motor delay have lower mastery motivation is inconclusive.

Objective

To examine differences between mental age matched toddlers with and without motor delay on various mastery motivation indicators.

Design

A mental age and gender matched case-control study.

Methods

Twenty-two children with motor delay, aged 23 – 47 months, and 22 children developing typically, aged 15 – 29 months were recruited. Persistence and mastery pleasure were measured with behavioral tasks that were moderately challenging for each child and with maternal ratings using the Dimensions of Mastery Questionnaire (DMQ). The DMQ was rated by the mother based on her perception of her child's motivation. Two types of structured tasks (a puzzle and a cause-effect toy selected to be moderately challenging for each individual child) were administered in a laboratory setting and recorded on videos. Paired t tests or Wilcoxon signed rank tests were used to examine group differences in persistence and mastery pleasure (α=.007; two tailed).

Results

Children with motor delay were rated lower on DMQ persistence than the typically developing group, but they did not show significantly lower persistence on the structured tasks. There were no significant differences in mastery pleasure between the two groups on either measure.

Limitations

Large within sample variability on the tasks and small sample size makes subgroup analysis (e.g., different severities) difficult.

Conclusions

Toddlers with motor delays did not show lower persistence and pleasure when given tasks that were moderately challenging; however, mothers tended to view their delayed toddlers as having lower motivation. Clinicians and parents should provide appropriately challenging tasks to increase children's success and motivation.
