Questionnaire Development Sequence: Key Steps

Developing a robust questionnaire involves a systematic process. The correct sequence ensures validity and reliability. Here's the breakdown:

Correct Sequence

The established order for developing a robust questionnaire is:

1. C. Item Discrimination Index: Initial screening of individual items to ensure they effectively differentiate between respondents. This is a fundamental psychometric check.
2. A. Curricular Validity: Assessing the relevance and appropriateness of the questionnaire content, ensuring it aligns with the intended domain or curriculum.
3. D. Exploratory Factor Analysis (EFA): Used to identify underlying latent structures or factors within the item pool when the structure is not yet clearly defined.
4. B. Confirmatory Factor Analysis (CFA): Testing a pre-specified factor structure to confirm if the data fits the hypothesized model. This follows EFA or theoretical expectations.
5. E. Norm Development: Establishing standardized scores based on a representative sample, allowing for interpretation of individual results relative to a group. This is a final step after the instrument is validated.

Explanation of Steps

This sequence prioritizes item quality and content relevance before exploring and confirming the underlying structure, culminating in standardization for practical application.

• Item Discrimination is essential early on to remove weak items.
• Curricular Validity ensures content relevance.
• EFA helps discover potential underlying constructs.
• CFA confirms a theoretically proposed structure.
• Norm Development provides a benchmark for score interpretation.
