The Early Independent Problem Solving Survey (EIPSS): Its psychometric properties in children aged 12–47 months

Independent problem solving (IPS) involves solving problems alone; with motivation and persistence; without watching others; or requesting or receiving help. The Early Independent Problem Solving Survey (EIPSS) was developed for 12- to 47-month-olds. Study 1 (N = 272) found good internal reliability and a 2-factor structure: Repetitive (repeatedly solvable problems, e.g., jigsaws) and Novel IPS (one-off problems, e.g., reaching out-of-reach toys). Study 2 (N = 567) confirmed good internal reliability and the 2-factor structure. Study 3 (N = 85) found a positive correlation between a divergent thinking lab measure and Novel IPS. Study 4 found good 6-month-longitudinal stability (N = 110) for the EIPSS and its subscales; and good agreement between parents (N = 32) for the Repetitive subscale. Study 5 (all data combined) demonstrated no item functioning differences across demographic variables. Differences for child age, child gender, parent age, and parent education were found for the EIPSS and subscales.
