A longitudinal study of the predictors of quality of life in patients with major depressive disorder utilizing a linear mixed effect model.

We set out in this study to examine a longitudinal dataset using a linear mixed effects model. Our ultimate aim is to identify predictors of the quality of life (QOL) domains and items amongst patients suffering from major depressive disorders. Four categories of variables are included in our analysis, composed of 'personal predisposition', 'psychosocial', 'illness-related' and 'time', while the outcome variables for this study are the 'physical', 'psychological', 'social' and 'environmental' domains of QOL, in conjunction with all of the items within the scale.

Evaluation of the psychometrics of the Social Impact Scale: a measure of stigmatization.

As stigmatization has a large impact on patients, therapists need a measure of this impact to provide patients with adequate services.

The study sample (N=580) included 237 patients with depressive disorder, 119 with schizophrenia, and 224 with HIV/AIDS.
