Dear Researcher! You can use the techniques of Exploratory factor analysis and Confirmatory factors analysis for psychological scale validation and reduction of number of items.

Daniel Oteng

There are several steps as the previous researchers have indicated. The use of EFA and Mean Score are some of the common techniques in reducing a number of items in a test. The link provided by Rasmus gives several options and clarifications on these techniques.
