An information-motivation-behavioral skills model of adherence to antiretroviral therapy.

HIV-positive persons who do not maintain consistently high levels of adherence to often complex and toxic highly active antiretroviral therapy (HAART) regimens may experience therapeutic failure and deterioration of health status and may develop multidrug-resistant HIV that can be transmitted to uninfected others. The current analysis conceptualizes social and psychological determinants of adherence to HAART among HIV-positive individuals. The authors propose an information-motivation-behavioral skills (IMB) model of HAART adherence that assumes that adherence-related information, motivation, and behavioral skills are fundamental determinants of adherence to HAART. According to the model, adherence-related information and motivation work through adherence-related behavioral skills to affect adherence to HAART. Empirical support for the IMB model of adherence is presented, and its application in adherence-promotion intervention efforts is discussed.     

The relation between recognition memory and classification learning

Two experiments investigated the relation between recognition memory and classification learning. The subjects were instructed that they would see a series of random-dot patterns and later would be asked to classify or to recognize the patterns. Following study, the subjects performed a classification task, a recognition-memory task, or both. It was found that classification-learning instructions were superior to recognition-memory instructions for the classification task, but that there was little or no effect of instructions on the recognition task. When subjects performed both recognition and classification tasks, there was no relation between saying “old” to a probe and correctly classifying it, except with old exemplars, and then only when the initial instructions had been to expect a recognition-memory test. Overall, the data show that classification and recognition can be experimentally separated. In addition, classification is often statistically independent of recognizing that items are old. These observed relations provide some constraints for the further development of models of classification learning and recognition memory.     

Behavioral weight reduction program for mentally retarded adult females

Behavioral treatment approaches to obesity in 17 mild-to-moderate retarded female adults were assigned to one of two experimental conditions, (a) behavioral self-control along with a physical activity component and (b) behavioral self-control. No significant differences were noted between groups on the indices of body weight and tricep skinfold thickness. A one-way analysis of variance with a repeated measure yielded a significant main effect of time for change in weight for both groups at the end of the 8-week treatment. Questions were raised about the possible role of nonspecific motivational factors versus cognitive factors in behavioral-weight reduction programs.     

Social reinforcement: A treatment component in verbal self-instructional training

This study investigated the effects of noncontingent social reinforcement on social and academic behaviors in grade school children. Twenty-four children in the second through fifth grades were selected on the basis of teacher ratings of disruptive behavior. Subjects were divided into (a) a high social reinforcement verbal self-instructional (VSI) training group, (b) a low social reinforcement VSI group, and (c) a no-contact control group. Children in VSI groups were removed from their classrooms during four 40-minute periods and given VSI training. Significant between-groups differences on measures of social reinforcement were found indicating its successful manipulation. While none of the dependent measures indicated significant differences between experimental groups, a consistent pattern of difference scores emerged giving limited support to the hypothesis that noncontingent social reinforcement contributed to behavioral gains. Results are discussed in terms of the need for future research on the effects of rapport on treatment outcome.Both authors wish to express their thanks to the Missoula public school administration, principals, psychologists, and teachers. Appreciation is also due to Matthew Firpo and Anita Fisher for their help in this project.     

The California Family Health Project: IV. Family structure/organization and adult health.

This research explores the relationships between each of four "domains" of family life and the health of husbands and wives in a community-based sample of 225 families. In this article we report the association between Family Structure/Organization and adult Health. This family domain refers to the architecture of the family or the structural frame of roles and rules within which the family operates. Interrelationships among 13 self-reported, family Structure/Organization scales are described, using principle components analysis (PCA) and multidimensional scaling analysis (MDS). Derived, joint-spouse or couple Structure/Organization variables also were created using inter-battery factor analysis. The PCA yielded a poor solution, whereas the MDS yielded a good two-dimensional solution, which roughly displayed the scales in a circular pattern for both husbands and wives. The analyses indicated that no single dimension or set of separate subdimensions adequately described the Structure/Organization variables. All 13 scales than were associated with a battery of 14 adult health scales for husbands and wives separately, using canonical correlation. Different aspects of family Structure/Organization were correlated with health for husbands and wives: Organized Cohesiveness, Sex Role Traditionalism, Role Flexibility and Shared Roles for husbands; and Organized Cohesiveness and Differentiated Sharing for wives. Different patterns of health scores also emerged by gender, with behavioral indicators, such as Smoking and Drinking, more salient for husbands, and mood indicators, such as Anxiety and Depression, more salient for wives.     

The California Family Health Project: II. Family world view and adult health.

This article explores the pattern of relationships between family World View and adult Health in a community-based sample of 225 families. Family World View refers to the beliefs, appraisals, and values that define a family's orientation to the world. The interrelationships among eight self-reported family World View variables are described, using principal components analyses (PCA) and multidimensional scaling analyses (MDS). Derived, joint-spouse World Views also are examined using inter-battery factor analysis. The World View variables then are analyzed as a set with 14 self-reported health variables for husbands and wives separately, using canonical correlation. The PCAs for family World View yielded poor solutions for both husbands and wives. The MDS displayed the eight variables in a circular pattern for husbands and for wives, indicating the absence of a single broad dimension, or subgroupings of separate dimensions, that could be used to "describe" the domain. In the canonical analyses, family World View was a strong correlate of Health, with approximately 50% of the variance accounted for by the respective canonical variates. For husbands, what we called Family Coherence, Family Religiousness, Family Life Engagement, and Family Optimism, were correlated with Health. For wives, Family Coherence, Family Religiousness, and Family Optimism, were correlated with Health. Different patterns of health scores emerged by gender, with behavioral indicators, such as Smoking and Drinking, more salient for husbands, and mood indicators, such as Anxiety and Depression, more salient for wives.     

The California Family Health Project: III. Family emotion management and adult health.

This article explores the broad patterning of interrelationships between family Emotion Management and adult Health in a community-based sample of 225 families. Emotion Management refers to how emotion is expressed, acknowledged, and managed by the marital partners. Fifteen reliable-observer ratings of husband-wife behavior were made during each of three 10-minute Emotion Management Interaction Tasks (EMITs). Each of the three tasks "pulled" for the expression of a different emotional theme: loss, intimacy, or conflict. A principle components analysis of the 15 ratings yielded a poor solution. A nonmetric, multidimensional scaling analysis described a two-dimensional, bipolar display with ordering among the variables in each of two wings. One dimension reflected positive versus negative Emotion Management characteristics, and the second reflected active and overt versus passive or covert emotional expression. The pattern of relationships among the couple ratings was similar for each of the three tasks. Using canonical correlation, the couple ratings demonstrated significant associations with 14 adult Health scores for both husbands and wives for the intimacy and conflict tasks, but not for the loss task. Specific gender patterns also emerged. In general, couple overt emotional aversiveness was negatively associated with husbands' health, and couple emotional avoidance/distance was negatively associated with wives' health.     

Individual Difference Correlates of the Experience of Sexual Harassment Among Female University Students1

Individuals often report experiences that conform to objective definitions of sexual harassment, but rarely report the subjective perception that they have been sexually harassed. The present research proposed that individual difference factors may mediate this commonly observed discrepancy. It was hypothesized that erotophobia, sexual inexperience, youth, sex role traditionality, repressing defensive style, and need for social approval have a weak inhibitory effect on reports of objectively defined experiences of sexual harassment, but a strong inhibitory effect on subjective perceptions that one has been sexually harassed. Results showed that individual difference factors including erotophobia, repressing defenses, and need for social approval were associated with fewer reported objective experiences of sexual harassment, while the base rate of subjective perception that one had been sexually harassed was very low, and this subjective perception was generally unassociated with individual difference factors. Discussion focuses on individual difference characteristics and motivation to ignore or to fail to report objective experiences of sexual harassment, and on suggestions for further research into the very high base rate of objectively defined experiences of sexual harassment and the very low base rate of perceived sexual harassment.
