Purpose
The aim of this study was to develop and validate a short form (SF) of the Smart Management Strategy for Health Assessment Tool (SAT) for cancer patients.
Methods
Data for item reduction were derived from cancer patient data (n = 300) previously used to develop the original SAT. We used regression methods to select and score the new SAT-SF. To assess the instrument’s reliability and validity, we recruited another 354 cancer patients from the same hospitals who were older than 18 years and accustomed to using the web. All results were compared with that of the long-form SAT (original SAT).
Results
The SAT-SF used is the shorter version, a 30-item (from the original 91-item) instrument, to measure cancer patient’s health. The 30-item SAT-SF explained 97.7% of total variance of the full 91-item long-form SAT. All SAT-SF subscales demonstrated a high reliability with good internal consistency compared with the original SAT. The total short-form scores of the three SAT sets (SAT-Core, SAT-Preparation, SAT-Implementation) differentiated participant groups according to their stage of goal implementation and percentage of actions taken in the 10 Rules for Highly Effective Health Behavior. We found acceptable correlations between the three SAT-SF sets and the additional assessment tools compared with the original SAT.
Conclusions
The 30-item SAT-SF had a satisfactory internal consistency and validity for cancer patients with minimal loss of information compared with the original SAT.
