Evaluation On Validity And Reliability Of Chinese Version Of Quality Of Life After Traumatic Brain Injury

Objective:Traumatic brain injuries (TBI) are one of the most common consequences of traffic accidents. Patients with mild, moderate or severe brain injuries suffer from physical, cognitive, behavioral, emotional and social problems. Most of these problems have been a long standing focus amongst practitioners and researchers. Only recently a development has started that took interest in the quality of life outcome of TBI patients. QOLIBRI(quality of life after traumatic injury) is the first specific scale to evalue the quality of life of the patients with TBI.To evaluate the validity and reliability of the Chinese version of QOLIBRI.Subjects:A preliminary surve was carried out among20outpatients or inpatients chosen at HuanHu Hospital,from December2007to May2008.Inclusion standard:Traumatic brain injury patients;Congnitive function is normal;TBI patients from17to68,from3months to18years.Exlusion standard:Spinal cord injury;Ongoing psychiatric disease or addiction;Drug or alchohol dependence;Can’t undertand or answer or cooperate;Terminal illness.Method:Qualified TBI patients were chosen through on-the-spot.After given the scale and directions, they were asked to fill up the Chinese version of QOLIBRI. They were asked to complete the same questionnaeir again and give it back to the investigator the following second week..All the data were analyzed with the statistic software SPPS10.0for social sciences, using of test-retest method to perform this investigation. Evaluation on reliability by test-retest reliability and cronbach’s alpha coefficient; Patients were asked to score the SF-36、GOSE、HADS、MMSE, and correlational analysis was applied for examining QOLIBRI’s reliability.Result:The response rates of outpatients and inpatients were100%.The analysis of retest reliability showed that the retest scores were significantly correlated with the initial test scores,with Pearson’s correlation coefficients ranging from0.915-0.995(p<0.001).The internl consistency analysis showed that The Cronbach’s alpha coefficient of subscales was the range from0.505to0.965and it was passable. The total score of QOLIBRI was positively correlated with that of SF-36(r=0.90,p<0.05) and GOSE (r=0.76,p<0.05), negatively correlated with that of HADS (r=-0.50,p<0.05),and no correlation with that of MMSE(r=0.24,p<0.050).The QOLIBRI has high reliability and validity,which can assess the quality of life with traumatic brain injury patients in our China.We use this scale to corelate the QOL with GCS and time since injured.The results showed that time since injury is corelated with bored and sad or depressed2items, with Pearson’s correlation coefficients0.87and0.56;It is corelated with pain1item, with Pearson’s correlation coefficients is0.69,so time since injury are correlated with bored, sad or depressed and pain.GCS is corelated with sad or depressed1item, with Pearson’s correlation coefficients is-0.54.It is corelated with slowness or clumsiness of movement,so GCS is correlated with slowness or clumsiness of movement and sad or depressed.Conclusion:The Chinese version of QOLIBRI has better reliability and validity. Time since injury are correlated with bored, sad or depressed and pain. GCS is correlated with slowness or clumsiness of movement and sad or depressed.
