The objective of this research was to study prevalence and related factors of anxiety and depression in 426 chronic back pain patients attending physical therapy treatment at Chiang Rai Prachanukor Hospital, Sawaan Pracharak Hospital, and Chao Phaya Yommarat Hospital. The questionnaires were used as a tool to measure and collected the key data which include demographic data, related symptom in back pain of patients, Thai-Hospital Anxiety and Depression Scale, Oswestry disability questionnaire, and Social support questionnaire (modified from The Personal Resource Questionnaire : PRQ Part II). The computer program was used in order to analyze all these data by using percent, mean, standard deviation, Chi-square or Fisher’s exact, one-way ANOVA, Pearson’s product moment correlation coefficiency and Linear regression. It can be concluded that most patients in this study were females (62%) in the 20 to 85 age group (mean=48.8); furthermore, most of them also worked as government officials, workers and agriculturists who did not have much salary for saving. The main cause of chronic back pain in the patient group was Lumbar Spondylosis at low back; in addition, sometimes patients also felt refer pain and weakness. Recurrent back pain was about once or twice a year; however, some patients had to absent from the work due to the pain. The major treatment was medicine, followed by physical therapy such as traction, hot pack, and the shortwave diathermy or microwave diathermy. Theduration of the treatment was between 3 and 6 months. From evaluating by anxiety and depression, the percent of the anxious patient group with doubtful cases (20.2%) was very nearby the depressed patient group with doubtful cases (21.6%), the number of anxious patient group with cases (30.8%) was very big different from the group of depressed patients with cases (8.7%). Besides this, it was found that the high degree of pain was related to the high degree of anxiety, depression, and disability because the pain could affect emotion, mind, jobs, and daily routine of the patients; nevertheless, high degree of social support could help the patients to reduce anxiety. The prevalence of anxiety and depression in chronic back pain patients, the major findings, were 30.8% and 8.7%, respectively and there were many related factors (e.g. Ages, educational level, jobs, salary, duration of disease, lesion, pain scale, refer pain, weakness, recurrence, type of treatment, pain-related work absent, and disability) could influence significantly on anxiety and depression (p<0.05). On the other hand, past history of psychiatry, past history of psychiatry in family members, diagnosis, treatment period and social support was associated significantly with anxiety (p<0.05), whereas marital status was related to depression at the significant level of 0.05 as well. According to the result of present study, findings and factors related to these patients group should be known, evaluated, and realized because it is extremely important in the way of improving the patients’ quality of life and providing effective treatment.
