Psychological sub-types among persons with HIV infection: an empirical study.

Cluster analysis was utilized to derive sub-types from a group of 53 males with HIV infection based on scores from several psychological measures. Measures administered included the Beck Depression Inventory, Life Orientation Test, Rosenberg Self-Esteem Test and the Internal Control Index. Three sub-types were identified: (1) average performing sub-type (2) severely dysfunctional sub-type, and (3) highly adaptive sub-type. All three sub-types showed different levels and patterns of test performance. Results are discussed in terms of sub-type characteristics and potential treatment issues.
