“…The direct administration of existing and previously validated versions of self-reported outcome measures in various countries, cultures and language groups, is therefore not always possible or advised. In these instances, misinterpretations of the questions or scoring systems, and culturally-inappropriate anchores or references, may compromise the integrity and validity of the responses that the outcome measure seeks [25,27-29]. The ramifications of utilizing linguistically- or culturally-inappropriate health outcome measures across various populations and cultures are therefore far-reaching; not only in terms of decisions made on effective care, but also in terms of health policies which may be developed from the research findings.…”

BackgroundPain catastrophization has recently been recognized as a barrier to the healthy development of physical functioning among chronic pain patients. Levels of pain catastrophization in chronic pain patients are commonly measured using the Pain Catastrophizing Scale (PCS).ObjectiveTo cross-culturally adapt and validate the South African PCS (SA-PCS) among English-, Afrikaans- and Xhosa-speaking patients with fibromyalgia living in the Cape Metropole area, Western Cape, South Africa.MethodsThe original PCS was cross-culturally adapted in accordance with international standards to develop an English, Afrikaans and Xhosa version of the SA-PCS using a repeated measures study design. Psychometric testing included face/content validity, internal consistency (Cronbach’s alpha-α), test-retest reliability (intraclass coefficient correlations-ICC), sensitivity-to-change and cross-sectional convergent validity (by comparing the adapted SA-PCS to related constructs).ResultsThe cross-culturally adapted English, Afrikaans and Xhosa SA-PCS showed good face and content validity, excellent internal consistency (with Chronbach’s α = 0.98, 0.98 and 0.97 for the English, Afrikaans and Xhosa SA-PCS, as a whole, respectively), excellent test-retest reliability (with ICC’s of 0.90, 0.91 and 0.89 for the English, Afrikaans and Xhosa SA-PCS, respectively); as well as satisfactory sensitivity-to-change (with a minimum detectable change of 8.8, 9.0 and 9.3 for the English, Afrikaans and Xhosa SA-PCS, respectively) and cross-sectional convergent validity (when compared to pain severity as well as South African versions of the Tampa scale for Kinesiophobia and the revised Fibromyalgia Impact Questionnaire).ConclusionThe SA-PCS can therefore be recommended as simple, efficient, valid and reliable tool which shows satisfactory sensitivity-to-change and cross-sectional convergent validity, for use among English, Afrikaans and Xhosa-speaking patients with fibromyalgia attending the public health sector in the Western Cape area of South Africa.

“…The PGIC is a standard assessment in clinical trials, and various forms of the PGIC have been used in all FM treatment trials (Table 2). A specific form of the PGIC has been linguistically validated into 12 languages to allow for use in FM research worldwide [22], and this form of the PGIC is recommended to assess overall/global improvement in combination with the FIQR (Table 1). …”

“…The BDI-II was also modified to include assessments for all nine DSM-IV criteria (the original BDI only met six of the nine criteria). The BDI-II has been linguistically validated into 12 languages for use in international FM treatment trials [22]. Normative data on the BDI and BDI-II are available.…”

“…The MASQ is a self-report measure comprising items to assess five cognitive domains including language, visuoperception, verbal memory, visual memory, and attention. While originally written in English, the MASQ has been translated and linguistically validated into 12 different languages to facilitate its use in international FM studies [22]. For this reason, the MASQ is recommended for assessment of cognitive dysfunction in fibromyalgia trials.…”

“…Four items in each subscale are answered on a 5-point Likert scale with item scores summed to yield subscale scores and a total score that varies between 20 and 100 with higher scores indicating more severe fatigue symptoms. The MFI is reliable and valid in FM patients [42], and it has been linguistically validated into 12 languages to enable use in international FM studies [22]. Normative data for the MFI is available for multiple subgroups including the general population [43].…”

Standard assessments for fibromyalgia (FM) diagnosis and core FM symptom domains are needed for biomarker development and treatment trials. Diagnostic and symptom assessments are reviewed and recommendations are made for standards. Recommendations for existing assessments include the American College of Rheumatology FM classification criteria using the manual tender point Survey for diagnosis, the brief pain inventory average pain visual analogue scale for pain intensity, the function subscale of the revised fibromyalgia impact questionnaire (FIQR) for physical function, the patient global impression of change and FIQR for overall/global improvement, the hospital anxiety and depression scale depression subscale for depression, the multiple ability self-report questionnaire for cognitive dysfunction, the fatigue severity scale for fatigue, the FIQR for multidimensional function/health-related quality of life, the jenkins sleep scale for sleep disturbance, and the fibromyalgia intensity score for tenderness. Forthcoming assessments including the FIQR for diagnosis, NIH PROMIS, and FIBRO Change scales are discussed.
