Characteristics of prospective memory deficits in HIV-seropositive substance-dependent individuals: preliminary observations.

The construct of "prospective memory" (PM) refers to a type of episodic memory for a future intention or "remembering what one must do." This function has been proposed as a candidate mechanism underlying behaviors of critical importance in HIV disease, including adherence with medication regimens and continued engagement in risk behavior. We administered tasks of time-based and event-based prospective memory and control tasks of retrospective and working memory to 31 HIV-seropositive and 35 HIV-seronegative substance-dependent individuals (SDIs).

Cognitive impulsivity and HIV serostatus in substance dependent males.

HIV-seropositive (HIV+) drug users show impaired performance on measures of integrity of prefrontal-subcortical systems. The Iowa Gambling Task (GT) is mediated primarily through ventromedial-prefrontal systems, and poor performance on this measure ("cognitive impulsivity") is common among substance dependent individuals (SDIs) as well as patients with disease involving prefrontal-subcortical systems (e.g.

Auditory working memory in HIV-1 infection.

We evaluated auditory working memory in 41 HIV-seropositive (HIV+) and 37 HIV-seronegative (HIV-) male drug users, employing a modified version of the Letter-Number Span Task developed by Gold and colleagues. We added a control condition to the standard task in order to evaluate more directly the contribution of the processing component to the working memory deficits with the effects of storage demands minimized. HIV+ subjects performed significantly more poorly compared to controls on an index of working memory processing derived from raw scores obtained under the two testing conditions.

Stress and coping of the African-American physician.

The purpose of this qualitative study was to examine the nature of work-related stress and coping experienced by African-American family physicians. Ten African-American family physicians across the state of Ohio were interviewed using a standardized open-ended format. Interview data were analyzed through an "editing" technique and QSR Nud*ist, a qualitative software program.

The impact of culture on physician stress and coping.

In a qualitative research study, a group of 10 community-based practicing family physicians were interviewed to determine their career values, sources of stress, and methods of coping. Research participants were identified as healthy and satisfied with their careers. To maximize the sample's diversity and determine potential racial differences in physician stress and coping, two African-American family physicians were requested to participate in the study.
