The Ktpc is composed of three subscales: planning (six items), execution (seven items) and evaluation (eight items).
The Ktpc is an instrument constructed to assess students' homework behaviour, as reported by parents or other tutors.
In essence, the Ktpc provides information about how frequently an individual uses self-regulated strategies to complete assignments.
The second goal was to explore the reliability of the results obtained in the Ktpc. Composite reliability results indicate that the scores in the Ktpc are highly reliable.
Although the differences in the groups' latent means were similar, whether the non-invariant items were considered or excluded, future gender and educational-level comparisons of the scores obtained in the Ktpc should be interpreted cautiously, given that only partial measurement invariance was obtained.
Consequently, future studies should explore the pertinence of maintaining these items in the Ktpc.
