=== Reliability ===
Internal Consistency: ''Cronbach’s alpha'' was 0.89 at the preoperative assessment (n = 111) and 0.92 at the 6-month follow-up (n = 56). All items correlated with the total score at >0.4. ''Test-Retest Reliability'': assessed on n = 68 with 24 h between assessments. The estimated mean (−0.12) of score differences was not significantly different from 0. The coefficient of reliability was calculated as 6.8 using the Bland and Altman method and 95 % of score differences fell between 0 and ±6.8. Overall, 83 % of score differences lay between 0 and ±4 points. The ''intraclass correlation'' was subsequently calculated as 0.83 <ref name=":0" />.

Evidence of convergent validity included large correlations (pre-op: r = 0.74 p < 0.01, post-op: r = 0.75 p < 0.01) between the OSS and the clinically assessed Constant Shoulder score (Constant & Murley, 1987). There was also moderate to high correlations (r > 0.49 to r = 0.86, p < 0.01) between the preoperative OSS questionnaire and relevant domains of the Health Assessment Questionnaire (HAQ) and the ''SF-36'' (particularly physical function and pain domains)<ref name=":0" />.

''Responsiveness''/''Sensitivity to Change'': Patients reported substantial improvement at the 6-month follow-up assessment. The ''effect size'' (1.2) was slightly larger for the OSS questionnaire than for any of the individual subscales of the HAQ or SF-36 questionnaires. The change scores for the OSS were significantly greater (p < 0.001) for patients who reported the most improvement in their condition using ''transition items''.<ref name=":0" /><span style="font-size: 20px; font-weight: normal;" class="Apple-style-span"></span>

Objective[edit | edit source]

Shoulder Pain

A questionnaire of shoulder pain and function. it was devised in 1996 (Dawson, Fitzpatrick, & Carr, 1996) for assessing the outcomes of shoulder surgery and later was used for degenerative conditions (excluding conditions of shoulder instability[1].

Intended Population[edit | edit source]

The OSS was designed to assess the outcome of all shoulder surgeries with the exception of instability surgery.

Method of Use[edit | edit source]

The oxford shoulder score

It contains 12 items, each with 5 answers. starting with 1 (best/fewest symptoms) to 5 (worst/most severe) which is awarded to correspond to the patient's symptoms. The total gives a minimum score of 12 and a maximum of 60. A higher score implies a greater degree of disability.

In 2009 the scoring method for the OSS was modified so that each of the 12 items is scored from 4 (best/fewest symptoms) to 0 (worst/most severe) [2].

Reference[edit | edit source]

The total score ranges from 48 to 0, after the modification of the score in 2009, a lower score indicates a greater degree of disability.

Reliability[edit | edit source]

the score was found to have a great interrater reliability and test-retest reliability[1].

Validity[edit | edit source]

Evidence suggested the validity of OSS to measure the degree of disability and detect the possible outcomes of shoulder surgery [1].

Responsiveness[edit | edit source]

it was stated that the sensitivity of the OSS can detect the smallest of changes that might happen in response to treatment interventions.[1]
