Assessing daily management in childhood diabetes

One hundred sixty-eight patients with childhood diabetes (6 to 19 years of age) and their parents participated in 24-hr recall interviews concerning daily diabetes management behavior. Each patient and parent was interviewed independently on three separate occasions. The information obtained was used to construct measures of 13 different adherence behaviors. Parent-patient agreement was good to excellent for most of the 13 behaviors. Agreement was influenced by the patient's age, with the most consistently high parent-child agreement found in the 10- to 15-year-old age group. Factor analysis of the 13 adherence behaviors resulted in a five-factor solution accounting for 70.6% of the variance. Adherence in childhood diabetes appears to be a complex construct, consisting of at least five different components unrelated to each other. Teenagers in this sample were less adherent than their younger counterparts on most of the adherence measures studied.     

Masculinity and Femininity: A Bipolar Construct and Independent Constructs

ABSTRACT The present investigation is a reanalysis of data from Antill and Cunningham (1979, 1980, Marsh, Antill, & Cunningham, 1987) consisting of responses to five masculinity-femininity (MF) instruments, two self-esteem instruments, and two social desirability scales Correlations between M and F for the five instruments varied from 23 to approximately - 10, support for distinguishable (nonbipolar) M and F factors was found for four of the instruments Applying confirmatory factor analysis (CFA) and hierarchical CFA (HCFA), the present study examined the dimensionality of MF and the influence of method/ halo effects m response to specific instruments The best fitting model identified three higher order factors, in support of traditional personality theories one factor was a bipolar MF construct, but m support of androgyny theory the other two factors were distinguishable M and F factors The factor structures were reasonably invanant for men and women, and methodological implications of this important finding were examined In subsequent analyses, the higher order MF factors were related to self-esteem, social desirability, and gender in order to further test interpretations of the MF factors.     

Young children's knowledge of their memory span: effects of task and experience

This study investigated the hypothesis that young children have knowledge about their memory that they may be unable to articulate, but are able to reflect on and use in problem-solving. Forty-eight kindergarteners made one of two types of judgments about their memory span for words. Half of the children made prospective verbal predictions about the number of words they thought they could recall from a list of 10. The other half made concurrent, nonverbal predictions by listening to words on a tape and manually stopping the tape when they heard as many words as they thought they could recall. Children's actual recall for words was then assessed. All children participated in multiple trials to assess the effect of task experience on their predictions. Analyses revealed that predictions made in the concurrent task were significantly more accurate than those made in the prospective task. All children lowered their predictions across trials, although only in the concurrent task were children's final-trial predictions not significantly greater than their actual recall. No meaningful effects or interactions were associated with actual recall scores. These results revealed that young children manifested greater memory knowledge when this knowledge was assessed through their concurrent problem-solving behavior rather than through their prospective verbal predictions.     

Aiming error under transformed spatial mappings suggests a structure for visual-motor maps

Transformed spatial mappings were used to perturb normal visual-motor processes and reveal the structure of internal spatial representations used by the motor control system. In a 2-D discrete aiming task performed under rotated visual-motor mappings, the pattern of spatial movement error was the same for all Ss: peak error between 90 degrees and 135 degrees of rotation and low error for 180 degrees rotation. A two-component spatial representation, based on oriented bidirectional movement axes plus direction of travel along such axes, is hypothesized. Observed reversals of movement direction under rotations greater than 90 degrees are consistent with the hypothesized structure. Aiming error under reflections, unlike rotations, depended on direction of movement relative to the axis of reflection (see Cunningham & Pavel, in press). Reaction time and movement time effects were observed, but a speed-accuracy tradeoff was found only for rotations for which the direction-reversal strategy could be used. Finally, adaptation to rotation operates at all target locations equally but does not alter the relative difficulty of different rotations. Structural properties of the representation are invariant under learning.     

The structure of honesty: Factor analysis of the reid report

The present study conducted principal component factor analyses of the Reid Report honesty test using two large (N=1281, N=3071) samples of applicants for employment. The results, which replicated across samples, strongly supported the existence of four major factors involved in the Reid Report measure of employee honesty. The Self-Punitiveness factor of the Reid Report contains items in which individuals indicate the extent to which they hold themselves to high standards of conduct. The Other-Punitiveness factor involves questions in which individuals indicate whether they are relatively harsh towards other people who commit crimes or act dishonestly. The Self-Projection factor of the Reid Report incorporates items in which individuals admit or deny that they have personal fantasies about dishonest behavior, such as taking company merchandise home with them. Finally, on the Other-Projection factor, respondents indicate the extent to which they see dishonest intentions or behaviors in others. Such results suggest a basis for more detailed assessments of a person's honesty than is provided merely by a single overall honesty score.This study was initiated while Dr. Ash was affiliated with Reid Psychological Systems, and was completed after he moved to London House, Inc. An earlier version of this study was presented by Dr. Ash at the Second Annual Conference of the Society of Industrial and Organizational Psychology, Atlanta, April, 1987.

Effects of cuing on short-term retention of order information

In two experiments, subjects recalled one of two letter sequences following a digit-filled retention interval. Recall performance was increased by precues informing subjects which letter sequence would be tested, and the cuing advantage remained throughout 60-digit retention intervals. No improvement was found, however, for cues occurring after the letters but before the digits. The cuing effects were attributed to encoding, not rehearsal, processes and were explained by a version of the Estes perturbation model, which included a long-term storage component and a fixed perturbation probability.     

Encoding difficulty and memory enhancement for young and older readers

Memory for text that required active construction (generation) on the part of the reader to comprehend some of the information was examined. (Letters were deleted from the words composing some of the idea units of the text). For both high school students and older adults, idea units that had letters deleted were remembered better than idea units with intact words on a cued-recall test. This pattern held for easier as well as for harder letter deletions. It was concluded that retention of textually presented information can be improved in older adults if the presentation format of the text induces or guides mental operations that support good encoding. Production-deficiency accounts and attentional/resource deficiency accounts of age-related text memory decrements are discussed in light of the present results.     

Women's emotional dependence on men: Scale construction and test of Russianoff's hypothesis

This study examines Russianoff's (1981) hypothesis that emotional dependence on men inhibits heterosexual women's self-esteem and life satisfaction. The Emotional Dependence Questionnaire (EDQ) was constructed to measure Russianoff's concept of desperate dependence. Fifty-four female first-year university students and 136 women from community organizations (Australian, nearly all Caucasian, and predominantly middle class and British/Celtic in origin) completed omnibus questionnaires comprising the EDQ and measures of self-esteem, life satisfaction, gender roles, feminist attitudes, and general dependence. Results indicated that women's emotional dependence on men, as defined by Russianoff, is a distinct form of dependence. In contrast to Russianoff's contention that heterosexual women uniformly display emotional dependence on men, it was found to be negatively associated with age, education, and feminist attitudes, and to be lower for career-oriented women. Life satisfaction was found to be greater for women in a relationship with a man. Implications of these findings are discussed, with recommendations for further validative and investigative studies using the EDQ.This paper is based on the first author's undergraduate honors thesis, conducted under the supervision of the second author. Gratitude is expressed to an anonymous reviewer for helpful comments on an earlier version.     

Adherence in childhood diabetes: results of a confirmatory factor analysis

In an earlier study (Johnson, Silverstein, Rosenbloom, Carter, & Cunningham, 1986), an exploratory factor analysis identified five components of adherence in childhood diabetes. In this investigation, a simultaneous confirmatory analysis was used to test the equality of this factor pattern across two independent samples. Factors 1 through 4--Exercise, Injection, Diet Type, and Eating/Testing Frequency-were confirmed. Factor 5--Diet Amount--proved to be too complex; the adherence measures comprising this factor (total calories and concentrated sweets consumed) are best treated as separate, single-indicator constructs. The results support a multivariate conceptualization of adherence, offer insight into the nature of the components underlying diabetes adherence, and provide measurement information for reliable component estimation.
