A Shortened Version of the Profile of Mood States

Key Points

• This research evaluates the feasibility of a shorter version of the Profile of Mood States for cancer patients.
• Eighty-three cancer patients completed the original 65-item Profile of Mood States.
• Items were eliminated based on internal consistency and face validity criteria.
• The final version contained 37 items with correlation coefficients above .95 compared to the original scale.
• The shortened scale showed an internal consistency coefficient alpha deemed acceptable.
• The correlation coefficients between the short and original scales exceeded .95, indicating high suitability.
• The reduction from 65 to 37 items did not compromise the ability to estimate mood scores.
