“…Our MCS-12 summary scores are similar to those reported in other rheumatoid arthritis and osteoarthritis populations (18), which are similar to the US norm. Although depression and anxiety are a common comorbid condition in patients who have arthritis and/or pain (27,28), it is plausible that the MCS-12 was not sensitive enough to detect differences in mental health symptoms between the dual and non-dual users in this study.…”

Objective. Inadequate prescription therapy pain management, lack of doctor-patient communication about over-thecounter (OTC) medications, and easy accessibility of OTC medications may contribute to patients using more than 1 medication to manage pain. It is well established that taking multiple nonsteroidal antiinflammatory drugs (NSAIDs) can lead to serious gastrointestinal problems. Little is known about whether use of more than 1 NSAID (i.e., dual use) is related to patient self-reported outcomes, specifically health-related quality of life (HRQOL). We hypothesized that dual use of NSAIDs would be associated with reduced HRQOL.

“…The SF-12 has been translated into many languages and has been validated for use in different ethnic groups. [7][8][9][10][11][12][13][14] In the translation stage, we followed the methodology adopted by the IQOLA. 23 Two factors were important in establishing the psychometric properties of the SF12: reliability and validity.…”

The health survey, the 12-Item Short-Form (SF-12) survey instrument, was developed as a shorter alternative to the SF-36 for use in scale studies. The aim of our study was to adapt this instrument into Moroccan Arabic and to examine its psychometric properties. The SF-12 was translated from English to dialectical Moroccan Arabic following the International Quality of Life Assessment translation procedure. The psychometric properties were tested in September 2007. Testing involved a sample of families and friends of patients (≥ 16 years old) in the diagnostic centre of the Fez University hospital, Morocco. The SF-12 was assessed by examining item-level characteristics, estimates of scale reliability (internal consistency) and construct validity. The study was conducted on 141 subjects. The physical component summary (PCS-12) and the mental health component summary (MCS-12) of the SF-12 demonstrated good internal consistency reliability, with alpha coefficients of 0.80 and 0.79, respectively. Multitrait analysis showed that the subscales of the SF-12 had good convergent and discriminant validity. Construct validity, assessed by the method of extreme groups, determined that the SF-12 summary scores varied for individuals who differed according to age and medical con¬ditions. The Moroccan Arabic version of the SF-12 appears to be a valid tool with which to for assess the health status of the general Moroccan population. On the other hand, issues such as test-retest reliability, longitudinal construct validity and responsiveness were not addressed in this study and should be considered in future ones.Peer reviewed.

“…HRQOL was measured using the short-form (SF)-12, version 2 (Quality Metric, Lincoln, RI), which has previously been used in evaluations of patients with RA. 22,23 The SF-12 consists of 12 questions asking patients to rate their quality of life during the past 4 weeks. The questionnaire produces 2 scores, a physical component score and a mental component score.…”
