One psychologist has developed a tool on Nature Connectedness. What would be the correct sequence of the following psychometric activities?

A. Carrying out Exploratory Factor Analysis
B. Establishing Percentile Norm
C. Examining Cronbach Alpha
D. Verifying Predictive Validity
E. Establishing Content Validity

Correct option is D

The correct sequence for psychometric activities in tool development is:

• C (Examining Cronbach Alpha):This step assesses the internal consistency (reliability) of the tool, ensuring items in the tool are correlated and measure the same construct
• E (Establishing Content Validity): This ensures the tool covers all relevant aspects of the concept being measured (Nature Connectedness in this case).
• A (Carrying out Exploratory Factor Analysis): This step identifies the underlying structure of the data and confirms whether the tool measures distinct factors of the construct.
• D (Verifying Predictive Validity): This step evaluates how well the tool predicts outcomes related to the concept (e.g., behaviors or attitudes associated with Nature Connectedness).
• B (Establishing Percentile Norm): Percentile norms are established to interpret scores by comparing them to a normative sample.

Information Booster:

1. Content Validity (Option E): Often involves expert review to assess whether all facets of the construct are represented.
2. Cronbach Alpha (Option C): Cronbach’s alpha can be written as a function of the number of test items and the average inter-correlation among the items.
3. Exploratory Factor Analysis (Option A): Extracts factors to confirm theoretical structure or highlight redundancies.
4. Predictive Validity (Option D): Ensures the tool’s scores have real-world relevance and application.
