Second, specificity may be improved by using the narrowest selleck screening library screen of SHERE 12 along with an additional tool such as the SF-12 Mental Component Scale, as suggested by Wilhelm et al (2008). Third, some further research is needed into the validity of the SPHERE 12 in different patient populations. Finally, clinicians should regard the SPHERE 12 primarily as a screening tool and the scores should be used to direct further investigations into the presenting signs and symptoms, rather than to diagnose mental disorders. “
“The Patient-Rated Elbow Evaluation (PREE) is a 20 item patient-reported outcome questionnaire that measures elbow-related pain and disability of the affected upper extremity (MacDermid 2001).

Its framework is consistent to its wrist counterpart Patient-Rated Wrist Evaluation (PRWE) (MacDermid et al 1998). The 20 items are categorised under 3 subscales. Five HER2 inhibitor items fall under the pain subscale; the remaining items measure functional disability. The specific activity subscale contains 11 of these items and addresses specific tasks which are difficult with elbow conditions; the final

four items address areas of usual role performance (personal care, household work, occupational work, and recreation) in relation to the previous capability/ role. Instructions to clients and scoring: Patients are asked to rate their pain and functional difficulty of the affected side on a 0–10 numeric rating scale. The pain subscale is anchored at 0 (no pain) and 10 (worst ever), while the two function sub scales are anchored at 0 (no difficulty) and 10 (unable to Florfenicol do). The subscale scores are combined to produce one single total score where pain and disability are equally weighted. The pain score is obtained by summing the 5 pain items (max. possible score = 50). The function score is obtained by summing the scores of 15 items and then dividing it by 3 (max. possible

score is 150/3 = 50). The total score is obtained by summing the pain score and the function score (max. possible score is 50 + 50 = 100). A higher total score indicates greater pain and disability. If an item score is missing then it can be replaced by the mean score of the particular subscale ( MacDermid 2010). Reliability: The PREE has been found to have a high internal consistency of 0.95 ( Vincent et al 2012). In the PREE developmental study ( MacDermid 2001) which included 70 subjects with various elbow pathologies from both postsurgical and non-surgical conditions, the PREE was found to exhibit excellent test-retest reliability (ICC = 0.95). Construct validity: Angst and colleagues (2005) found the PREE to exhibit moderate to high correlations with the patient-reported form of the American Shoulder and Elbow Surgeons questionnaire elbow form (pASES-e) (Spearman’s rho 0.92) and the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) (Spearman’s rho 0.68) in a sample of total elbow arthroplasty patients.
