The purpose of this study is to identify the effectiveness of integrative therapy treatment towards
depression and aggression among prison inmates. Integrative therapy in this study refers to treatment
module which are consisted of four integrated theories in a counselling process. It involved the
combined therapy of Person Client Centred (PCC), Rational Emotions Behaviour Therapy (REBT)
and Choice Theory Reality Therapy (CTRT) as technical treatment. Meanwhile, Stimulus Organism
Response (SOR) act as educational principle or training. Integrative therapy is conducted on the
respondents for six session of group counselling. This study is a quasi-experiment involving 160 depressed prison inmates (80 treatment; 80 control) and 140 aggressive inmates (70 treatment; 70
control) from five prison institutions as the respondent for this study using purposive sampling.
Inmates are identified as respondents using high cutting point of depression using Beck Depression
Inventory (BDI) and high aggression using Aggressive Questionnaires (AQ). For the data analysis, nonparametric
test such as Mann-Whitney Test and Wilcoxon Signed Rank Test were used based on the
normality test using Kolmogorov-Smirnov and Shapiro-Wilk test. Result from the Mann-Whitney Test
shows that the treatment group had higher declining rate as compared to the controlled group for
depression and aggression. Wilcoxon Signed Rank Test also shows the same result as the treatment
group indicates a decline in rate from the pre and post of the treatment compared to the controlled
group. The results of this study are hope to act as the medium for using integrative model which is
rarely use in studies in this country especially in the field of treatment for prison inmates. It is also
expected that it can be applied in different setting which offer treatment service such as hospitals,
social work institution, police institute, schools, higher learning institutions and others.
