Ethnic matching and treatment outcome with Hispanic and Anglo substance-abusing adolescents in family therapy.

This study examined treatment outcomes of 86 highly acculturated Hispanic and Anglo substance-abusing adolescents in functional family therapy, testing the hypothesis that ethnic matching of therapist and client is related to better treatment outcomes for clients. Adolescents reported on their substance use pre- and posttreatment on a timeline follow-back interview. Ethnically matched Hispanic adolescents demonstrated greater decreases in their substance use compared with Hispanic adolescents with Anglo therapists. Ethnic match status was not related to treatment outcome for Anglo clients. Thus, the matching hypothesis was supported for Hispanic clients only. The results underscore the importance of greater ethnic diversity among therapists and better cultural competency training for Anglo therapists. More research is needed on individual differences in the effects of ethnic matching.     

The Effects of Social Roles and Personality Motives on Autobiographical Memory

In the present study we examined how agentic and communal social roles and personality motives were related to the quality (including emotions and agentic and communal themes) and cognitive structure (differentiation and integration) of women's autobiographical memories. One hundred twenty-seven college-aged women were asked to describe a personal memory after being randomly assigned to either agentic or communal task conditions. In the agentic task condition, participants completed a creative building task alone, and in the communal task condition, participants completed the same task with a confederate. Personality motives were measured by both explicit (self-report) and implicit (TAT stories) measures. Following the task, participants wrote about an autobiographical experience in which they were in either agentic or communal social roles. Linear multiple regression analyses indicated that participating in an agentic task, as compared to a communal task, was related to the inclusion of fewer agentic themes as well as to a higher frequency of shame and anger words in autobiographical memories. Congruence between social roles and implicit personality motives (e.g., an agentic task assignment and high agentic motives) yielded less negatively laden autobiographical memories than incongruence between social roles and personality motives (e.g., an agentic task assignment and high communal motives). Furthermore, participants who scored high on both explicit agentic and communal motives included more positive emotion words in their memories than did other groups.     

Mental relaxation improves long-term incidental visual memory

Experimental evidence has linked increased arousal to enhanced memory retention. There is also evidence that procedures reducing arousal, i.e., mental relaxation, might improve memory, but conflicting results have been reported. To clarify this issue, we studied the effects of a single session of relaxation training on incidental visual long-term memory. Thirty-two relaxation-naive subjects viewed 280 slides without being told that there would be subsequent memory testing. Afterwards, subjects listened to a 12 min relaxation tape; 16 subjects relaxed by following the instructions (relaxation group), and the other 16 subjects pressed a button whenever a body part was mentioned (control group). While listening to the relaxation tape, high frequency heart rate variability (HRV) was greater and low frequency HRV was lower in the relaxation group, implying effective relaxation and increasing parasympathetic activation. The relaxation group had superior memory retention 4 weeks later (p = .004), indicating enhancement of long-term memory performance. This effect could not be explained by retroactive interference experienced in the control group because short-term memory performance immediately after the tape was slightly better in the control group. Retention of materials acquired after the relaxation session remained unaffected, suggesting relaxation has retrograde effects on memory consolidation. Our data demonstrate a favorable influence of relaxation on at least this aspect of learning. Our data also extend previous knowledge on the beneficial effects of ascending parasympathetic stimulation on memory retention in that enhanced long-term memory consolidation may also occur in the presence of central and descending parasympathetic activation triggered by willful psychomotor activity.     

What makes placebo-controlled trials unethical?

The leading ethical position on placebo-controlled clinical trials is that whenever proven effective treatment exists for a given condition, it is unethical to test a new treatment for that condition against placebo. Invoking the principle of clinical equipoise, opponents of placebo-controlled trials in the face of proven effective treatment argue that they (1) violate the therapeutic obligation of physicians to offer optimal medical care and (2) lack both scientific and clinical merit. We contend that both of these arguments are mistaken. Clinical equipoise provides erroneous ethical guidance in the case of placebo-controlled trials, because it ignores the ethically relevant distinction between clinical trials and treatment in the context of clinical medicine and the methodological limitations of active-controlled trials. Placebo controls are ethically justifiable when they are supported by sound methodological considerations and their use does not expose research participants to excessive risks of harm.     

Child resiliency in inner-city families affected by HIV: the role of family variables

This study examined the role of family variables in child resiliency within a sample of African-American, inner-city children whose mothers are HIV-infected. Variables from three dimensions of the family were included: family structural variables, maternal variables, and mother-child (parenting) variables. The participants were 82 children between the ages of 6 and 11 and their HIV-infected mothers. Correlational analyses indicated that resiliency was associated only with three parenting variables: parent-child relationship, parental monitoring, and parental structure in the home. Hierarchical regression analyses indicated a multiplicative relationship between parental monitoring and parent-child relationship and between parental monitoring and parental structure in the home, suggesting that parenting variables potentiate each other. Clinical implications of the findings are considered.     

Influences upon willingness to participate in schizophrenia research: an analysis of narrative data from 63 people with schizophrenia

Schizophrenia affects more than 1% of the world's population, causing great personal suffering and socioeconomic burden. These costs associated with schizophrenia necessitate inquiry into the causes and treatment of the illness but generate ethical challenges related to the specific nature and deficits of the illness itself. In this article, we present a systematic analysis of narrative data from 63 people living with the illness of schizophrenia collected through semistructured interviews about their attitudes, beliefs, and experiences related to psychiatric research. In the comments of these individuals, half of whom had had prior personal experience in research protocols, we identified factors influencing openness toward research involvement as well as deterrents that appear to lessen interest in participation. Clear response pattern differences emerged between those with prior research experience and those without such experience. In the discussion, we explore the key findings and outline the implications for safeguards in mental illness research.
