An "open-transformed scale" for correcting ceiling effects and enhancing retest reliability: the example of pain

The use of closed scales (with anchors at each end) to measure pain was found to produce ceiling effects characterized by a deceleration of ratings toward the upper end of the scale. This was consistent with previous research. Apart from producing nonlinear functions, the closed scale also limited test-retest reliability because of subjects' tendencies to correct their distorted ratings in subsequent trials. However, an open-ended scale coupled with transformation of reported ratings into a decile scale virtually eliminated the ceiling effect, thus producing consistently linear functions and maximizing test-retest reliability. This finding may have implications for the measurement of other sensory and psychological phenomena, especially those in which the property evaluated varies in a continuous fashion.     

Assessing perceptions of occupational-family integration

Consideration of how to integrate occupational and family roles is crucial to the psychological development of adolescents and young adults today. This paper reports on a self-report instrument designed to assess perceptions of involvement in occupational and family roles in young women and men. The Orientations to Occupational-Family Integration consists of three separate scales that reflect three types of orientation—(1) male traditional, (2) female traditional, and (3) male and female atraditional. Reliability and validity data are reported from two studies, one with 81 adolescent girls and one with 122 college women and men. Uses of the measure for research and educational purposes are described briefly.Appreciation is expressed to Sue Lucas and Darryl Lewis for their assistance in data collection for Study I, and to the University Research Institute at the University of Texas at Austin for grant awards for each of the two studies.

Psychotherapy With African American Men: What We Know and What We Need to Know

African American men are at an increasingly high risk of experiencing psychological disturbances. Strategies for establishing effective therapeutic relationships with these clients are provided in the literature. Notably absent are empirical data pertaining to the effectiveness of psychotherapy with African American men. This article reviews the literature on psychotherapy and proposes an agenda for the next decade of research with African American male clients.     

The relationships among verbal short-term memory, phonological awareness, and new word learning: evidence from typical development and Down syndrome

This study examined the correlates of new word learning in a sample of 64 typically developing children between 5 and 8 years of age and a group of 22 teenagers and young adults with Down syndrome. Verbal short-term memory and phonological awareness skills were assessed to determine whether learning new words involved accurately representing phonological information in memory. Results showed a relationship between verbal short-term memory measures and typically developing individuals’ ability to learn the phonological form of novel words but not their ability to learn the physical referent of new words. Similarly, individuals with Down syndrome showed impaired verbal short-term memory and impaired form but not referent learning. Together, these findings specify the circumstances in which an accurate phonological representation within short-term memory is required for new word learning.     

How Category Selection Impacts Inference Reliability: Inheritance Inference From an Ecological Perspective

This article presents results from a simulation-based study of inheritance inference, that is, inference from the typicality of a property among a “base” class to its typicality among a subclass of the class. The study aims to ascertain which kinds of inheritance inferences are reliable, with attention to the dependence of their reliability upon the type of environment in which inferences are made. For example, the study addresses whether inheritance inference is reliable in the case of “exceptional subclasses” (i.e., subclasses that are known to be atypical in some respect) and attends to variations in reliability that result from variations in the entropy level of the environment. A further goal of the study is to show that the reliability of inheritance inference depends crucially on which sorts of base classes are used in making inferences. One approach to inheritance inference treats the extension of any atomic predicate as a suitable base class. A second approach identifies suitable base classes with the cells of a partition (of a preselected size k) of the domain of objects that satisfies the condition of maximizing the similarity of objects that are assigned to the same class. In addition to permitting more inferences, our study shows that the second approach results in inheritance inferences that are far more reliable, particularly in the case of exceptional subclasses.     

Psychological skills and mindfulness training effects on the psychological wellbeing of undergraduate music students: An exploratory study

This study explored the efficacy of psychological skills and mindfulness training intervention on the psychological wellbeing of undergraduate music students. Participants were undergraduate music students (n = 36) from the Department of Music at a South African university, 21 of whom were elected to take the psychological skills and mindfulness training intervention. Data on their self-reported psychological wellbeing, psychological skills, mindfulness and performance anxiety levels were collected pre-and post-intervention. The analysis applied non-parametric procedures to determine changes in students’ psychological wellbeing after the seven-week intervention programme. Findings suggest improvements in psychological wellbeing, psychological skills, mindfulness and performance anxiety with training. Psychological skills and mindfulness training may have benefits to the psychological wellbeing of music students.

Effects of stress on methyltransferase synthesis: an important DNA repair enzyme

The enhancement of tumor development following acute stress has been demonstrated in some animal studies. This study was designed to explore mechanisms that would account in part for the relationship between stress and tumor development at the level of DNA repair, using a rat model. Forty-four rats were given the carcinogen dimethylnitrosamine in their drinking water, and half were randomly assigned to a rotational stress condition. The levels of methyltransferase, a DNA repair enzyme induced in response to carcinogen damage, were significantly lower in spleens from the stressed animals. These data suggest that stress may impair DNA repair.     

The Relationships of Primary Appraisals of Infertility and Other Gynecological Stressors to Coping

Women experiencing infertility, pregnancy, medical gynecological problems, or annual checkups were assessed for primary appraisal of their stressor and types of coping strategies used. Diagnostic category approximated the subjective appraisal of stressor for pregnant (challenge) and checkup (no stress) groups. Most participants in the medical gynecological problems group appraised their stress as a threat, but a few participants chose other appraisal categories. Infertility was associated with two categories of appraisal—loss and challenge. Participants appraising their stressor as a loss made greater use of the coping strategies of Action, Wishful Thinking, and Fatalism than did women appraising their stressor as a challenge, a threat, or not stressful. Women appraising infertility as challenge were less distressed than women in any other group. The bimodal perception of infertility has implications for treating women who seek psychological help.
