This thesis had two major aims: the first was aimed to test the efficacy of an Individual Cognitive Behavior Therapy for treatment of unipolar mood disorders with suicidal behavior and the second was to evaluate the risk and protective factors for suicidal behavior among patients with unipolar mood disorders in Malaysia. A review of literature on suicidal behavior in Malaysia suggested that lack of suicidal behavior-related measurements has been hindrance in identification of the risk and protective factors for suicidal behaviors. In addition, the investigation of variables that predicts treatment outcomes for patients with unipolar mood disorders with suicidal behavior has also been Confirmatory Factor Analyses were used to examine the psychometric properties and to establish the reliability and validity of these instruments. These measures were validated using the sample size of 483 from both medical and psychiatry patients. All the measures were found to have good reliability and validity using the exploratory and confirmatory factor analyses.Chapter 7 compared the two groups and the results showed that psychiatry patients had significantly higher mean scores on risk factors (hopelessness, psychological distress, depressive, anxiety and stress symptoms) and lower mean scores on protective factors (reasons for living, self esteem, hopefulness, satisfaction with life and social support) for suicidal behavior as compared to medical patients. In addition, patients with suicidal ideation had significantly higher mean scores on risk factors and lower mean scores on protective factors for suicidal behavior as compared to patients iii without suicidal ideation. And finally, there was a significant interaction between diagnosis (psychiatry patients with suicidal ideation, psychiatry patients without suicidal ideation, medical patients with suicidal ideation and medical patients without suicidal ideation) and suicidal behavior (suicidal ideation).Chapter 8 is a controlled trial comparing the Treatment As Usual (TAU) (N=36)
DASS-D, BHS-T, DASS-A, DASS-S) and measures of protective factors for suicidal behavior (RFL-T, RSE-T, AHTS-T, PRS-T, SWLS-T, PSR-FR, PSR-FM, SCB, MO, RF, FS, FSD, and CC)were administered at pre, mid, post, 3 months follow-up and 6 months follow-up for both groups.The TAU groups received outpatient treatment as usual by the psychiatrists of the hospital. The results showed that the TAU+ICBT groups consistently and significantly scored better on most of measures when compared to the TAU group. In addition, the TAU+ICBT group improved at earlier stage and the rate of improvement was significantly faster than the TAU group. The TAU group had significant improvement on seven dependent measures only. Thus the addition of the ICBT to TAU produced a more generalized and significant improvement on all the measures of depressive symptoms, measures of suicide ideation symptoms, measures of risk and protective factors of unipolar mood disordered with suicidal ideation patients.The general discussion o...
