Source apportionment of social support and quality of life index among drug abuse inmates using multiple linear regression
Drug addictions are some of the contributing factors to low level of quality of life (QoL) and other psychological problems in individuals. Studies on the influence of social support on the QoL of inmates with drug abuse dependency have identified that inmates who maintain close contact with their family and friends associated themselves with better satisfaction in interpersonal relationships. This study intends to show the effectiveness of Factor Analysis (FA) and Multiple Linear Regression (MLR) for the assessing quality of life indicator sources. The data from 12 prisons selected in Peninsular Malaysia was collected during the period April and June 2015. The 1753 respondents were selected using simple random sampling. The method of FA has identified five significant index categories- Excellent, Good, Moderate, Low and poor quality of life index (QoLi) were generated from FA.
