The purposes of this quasi-experimental research using the pretest- posttest randomized control group design were: 1) to compare the quality of life in bipolar disorder patients before and after received group psychoeducation program, and 2) to compare the quality of life in bipolar disorder patients who received group psychoeducation program and those who received regular caring ativities. The 36 samples were bipolar disorder patients, who sought for received services in our patients department, Somdetchaopraya hospital. The samples were matched pair according to gender, depression scores and mania scores, and then randomly assigned into experimental group and control group, 18 subjects in each group. The experimental group received group psychoeducation program.Whereas the control group received regular caring activity. The research instruments consisted of:1) group psychoeducation program, 2) Knowledge on Bipolar disorder test, 3)The Negative Event Scale, 4) WHO-BREF THAI, 5) Montgomery Asberg Depression Rating Scale, and 6) Young Mania Rating Scale. The 1st, 2nd and 3rd instruments were validated for content validity by 5 experts. The reliability of the 2nd instruments was reported by KR-20 as of 0.78. The reliability of the 3rd, 4th, 5th and 6th instruments were reported by Chronbach Alpha as of 0.74, 0.79, 0.79 and 0.75 respectively. The t-test was used in data analysis.
Major finding were as follows: 1. The score on quality of life in bipolar disorder patients after received group psychoeducation program was higher than that before the experiment (t=8.65, p< 0.05). 2. The score on quality of life bipolar disorder patients after received group psychoeducation program was higher that those who received the regular caring activity (t=2.32, p< 0.05).
