Early impact of the BEST intervention for parents stressed by adolescent substance abuse

Youth involvement in substance abuse can be a source of considerable distress for their parents. Unilateral family interventions have been advocated as one means by which concerned family members can be supported to assist substance‐abusing family members. To date there has been little research examining the impact of unilateral family interventions on the directly participating family members. In this study the early impact of an 8‐week parent‐group programme known as Behavioural Exchange Systems Training (BEST) was evaluated using a quasi‐experimental, waiting list control design. The professionally led programme had been developed to support and assist parents in their efforts to cope with adolescent substance abuse. Subjects were 66 parents (48 families) accepted for entry into the programme between 1997 and 1998. Comparison was made between 46 parents offered immediate entry into the programme and 20 parents whose entry to the programme was delayed by an 8‐week waiting list. At the first assessment 87% of parents showed elevated mental health symptoms on the General Health Questionnaire. Evidence suggested exposure to the intervention had a positive impact on parents. Compared to parents on the waiting list, parents entered immediately into the intervention demonstrated greater reductions in mental health symptoms, increased parental satisfaction, and increased use of assertive parenting behaviours.

Attributing “Third World Poverty” in Australia and Malawi: A Case of Donor Bias?1

Causal attributions for poverty in the developing world were examined from the perspectives of “actors” living in a “developing country” (Malawi) and “observers” living in a “developed country” (Australia). Ninety‐eight Malawian and 100 Australian weekend shoppers responded to the Causes of Third World Poverty Questionnaire (CTWPQ) and the Just World Scale (JWS), with Australian participants also providing information about their frequency of donating to foreign‐aid charities. Consistent with the actor–observer bias, Australians were more likely than were Malawians to attribute poverty to dispositional characteristics of the poor, rather than to situational factors. Among the Australians, situational attributions were in turn associated with frequency of donation behavior. The finding of a donor bias in this sample has important implications for the social marketing of foreign aid to Western donor publics.     

Prompt comprehension in UNIX command production

We hypothesize that a cognitive analysis based on the construction-integration theory of comprehension (Kintsch, 1988) can predict what is difficult about generating complex composite commands in the UNIX operating system. We provide empirical support for assumptions of the Doane, Kintsch, and Polson (1989, 1990) construction-integration model for generating complex commands in UNIX. We asked users whose UNIX experience varied to produce complex UNIX commands, and then provided help prompts whenever the commands that they produced were erroneous. The help prompts were designed to assist subjects with respect to both the knowledge and the memory processes that our UNIX modeling efforts have suggested are lacking in less expert users. It appears that experts respond to different prompts than do novices. Expert performance is helped by the presentation of abstract information, whereas novice and intermediate performance is modified by presentation of concrete information. Second, while presentation of specific prompts helps less expert subjects, they do not provide sufficient information to obtain correct performance. Our analyses suggest that information about the ordering of commands is required to help the less expert with both knowledge and memory load problems in a manner consistent with skill acquisition theories.     

Do Additional Features Help or Hurt Category Learning? The Curse of Dimensionality in Human Learners

The curse of dimensionality, which has been widely studied in statistics and machine learning, occurs when additional features cause the size of the feature space to grow so quickly that learning classification rules becomes increasingly difficult. How do people overcome the curse of dimensionality when acquiring real‐world categories that have many different features? Here we investigate the possibility that the structure of categories can help. We show that when categories follow a family resemblance structure, people are unaffected by the presence of additional features in learning. However, when categories are based on a single feature, they fall prey to the curse, and having additional irrelevant features hurts performance. We compare and contrast these results to three different computational models to show that a model with limited computational capacity best captures human performance across almost all of the conditions in both experiments.     

EDUCATING ABOUT WOMEN AND GENDER

This study assesses the multiple effects of planned exposure to gender and women's issues on graduate student development. Students in a gender-aware Counseling Psychology program (n = 63) were compared to those in two other graduate psychology programs (total n = 38) on five scales that measured exposure to gender issues, social constructivist views, feminist identity development, performance self-esteem, and endorsement of feminist therapy goals and strategies. Results supported the hypotheses that all outcome measures were significantly correlated with the extent of academic experiences related to women and gender. Program of concentration and level of graduate training were differentially related to social construction views and stages of feminist identity development. We discuss these findings in terms of their implications for gender-aware education in the development of student identity, attitudes, and professional practice.     

The benefits of expressive writing on sleep difficulty and appearance concerns for college women

The college years represent an important developmental period in the lives of young women, who report health-related difficulties such as sleep disturbance and body/eating concerns. This study explored whether expressive writing (EW) can decrease health-relevant complaints among college women. College females (n?=?111) were randomised into an EW condition (writing about body concerns) or a control writing condition and completed three 15-min writing sessions. Results indicate that participants in the EW condition reported less sleep difficulty and less body-focused upward social comparison at 8-week follow-up, relative to control participants. For individuals who reported higher perceived stress at baseline, the EW condition resulted in less eating disturbance and less social comparison, relative to the control condition. The effect of EW on eating disturbance for those who were high in stress was partially mediated by the change in upward social comparisons focused on one's body. These findings suggest that EW about body image and appearance concerns may positively influence the trajectory of risk for, or resilience against, future complications as a result of sleep difficulty, eating disturbance and body dissatisfaction.
