| Objective: To translate cross-culturally the Japanese GLFS-25(the 25-question Geriatric Locomotive Function Scale) into Chinese and evaluate the reliability,validity,responsiveness in preliminary test,then explore the applicability of Chinese GLFS-25 in the elderly of musculoskeletal disease.Meanwhile exploring personal experience of the elderly patients with locomotive syndrome,then provide theoretical basis for futher interventions and health guidance.Methods:1 The GLFS-25 was authorized by original author,then translation and adaptation were conducted using a systematic approach with the following steps: forward translation, synthesis, back-translation, consolidation of translations with expert committee, and pre-testing.A total of 500 orthopaedic outpatients aged 60 years were recruited using convenience sampling and orthopaedic diseases were diagnosed by board-certified orthopaedic surgeons.Item Analysis,internal consistency,rest-retest reliability,criterion validity,construct validity,convergent and divergent validity were applied to test the reliability and validity.2 Using the sex,age,BMI,exercise habit,level of education,waist circumference,residence,job in the past,history of falls during the previous 1 year,categories of orthopaedic diseases as independent varibles,a logistic regression was perfomed to analyse data and explore the main influence factors in patients of locomotive syndrome.3 The informants of locomotive snydrome were interviewed with purposive sampling in qualitative analysis,then analysed with Colaizzi's phenomenological method to explore the expirences of symptoms,influence and coping strategies on the quality of life.Results:1 During the process,3 items were reformulated based on the participants' responses and the opinions of expert committee.Furthermore, the study showed promising results concerning the psychometric properties of the GLFS-25(e.g.Cronbach's alphas for the scale was 0.95, and good content validity).Factor analyses indicated four-dimensionality of the scale,the cumulative variance contribution rate was 64.263%. Internal consistency was confirmed by Cronbach's a coefficient of 0.927,the Cronbach's a of four factors was 0.751,0.852,0.840 and 0.933 respectively;the test-retest interclass correlation was 0.791-0.949.As for the association between the GLFS-25 and European Quality of Life Scale 5-Dimension(EQ-5D), Spearman's correlation coefficient was 0.854,showing excellent criterion validity.2 Mean value of the GLFS-25 score was 26.22±16.94,323 were in the locomotive syndrome group(GLFS-25 scores of?16).Univariate analysis showed that there was a significant difference with sex,age,exercise habit,level of education,waist circumference,residence,job in the past,history of falls during the previous 1 year and categories of orthopaedic diseases between LS group and non-LS group.Odds ratios of these significant varibles were estimated using logistic regression analysis.Female,age,history of falls during the previous 1 year,knee Osteoarthritis,hip Osteoarthritis and degenerative lumbar disease were the risk factors for LS,and exercise habit was protect factor.3 With the principle of data saturation,the sample size in qualitative research was eight.Four main themes were classified through analysis: self-correction, lower quality of life,worried,coping.Conclusions: The GLFS-25 offered a valid and reliable questionnaire scale for detecting locomotive syndrome in Chinese elderly,and it also provided evidence for preventing and treating musculoskeletal disease.Through exploring influence factors of locomotive syndrome in the elderly and the symptoms experiences in qualitative research, the results provided theoretical basis for further interventions. |
