Comments/Special Instructions
Scoring:  Domain scores range from 0-100. Higher scores mean higher satisfaction on each domain.
 
Background: Although numerous disease-specific measures of patients' treatment satisfaction for medication (TS-M) have been reported in the literature, less attention has been paid to developing a more general measure of TS-M--one that would permit comparisons across medication types and patient conditions. To fill this gap, the TSQM was developed. The abbreviated 9 item TSQM (TSQM-9, developed in 2008) is derived from the TSQM Version 1.4 (developed in 2004) but without the five items of the side effects domain.
Rationale/Justification
Strengths/ Weaknesses:  The use of TSQM-9 over the earlier versions of the TSQM is not recommended in clinical studies where there is no possibility of the side effects domains interfering with study objectives and where the outcome of investigational drugs are being studied.
 
Psychometric Properties: High test-retest reliability
Administration: 5-10 minutes
