Maintenance of Treatment Gains: A Comparison of Enhanced,Standard, and Self-directed Triple P-Positive Parenting Program

This report describes the 3 year outcomes of three different variants of the Triple P-Positive Parenting Program, a behavioural family intervention. Families were randomly assigned to one of three intervention conditions or to a waitlist condition. At 1 year follow-up there were similar improvements on observational and self-report measures of preschooler disruptive behaviour for Enhanced, Standard and Self Directed variants of Triple P. At 3 year follow-up (completed by 139 families), each condition showed a similar level of maintenance of intervention effects. Approximately 2/3 of preschoolers who were clinically elevated on measures of disruptive behaviour at pre-intervention moved from the clinical to the non-clinical range. Across conditions, there was a comparable preventive effect for each intervention for these high risk children. The implications of the findings for the development of brief, cost effective parenting interventions within a public health framework are discussed.     

Exercise is positively related to adolescents' relationships and academics.

Eighty-nine high school seniors were administered a questionnaire that gathered information on their exercise habits (ranging from rarely to daily), relationships with parents and peers, depressive tendencies, sports involvement, drug use, and academic performance. Students with a high level of exercise had better relationships with their parents (including greater intimacy and more frequent touching), were less depressed, spent more time involved in sports, used drugs less frequently, and had higher grade point averages than did students with a low level of exercise.     

A test of sex differences in aggressive response to hypothetical conflict situations

Male (n = 289) and female (n = 268) college students were administered the Leifer-Roberts Response Hierarchy (Reinisch Revision) to evaluate the utility of this measure in reflecting sex differences in self-described potential for aggressive response. The Response Hierarchy provides a retrospective estimate of where physical and verbal aggression reside in an individual's hierarchy of possible behavioral responses to hypothetical conflict situations in adolescence. A score is obtained for: (a) physical aggression, (b) verbal aggression, (c) nonaggressive coping, and (d) withdrawal. When asked to respond as they would have or did at age 13 years, verbal aggression was the most frequent response with no significant sex difference in mean scores. Men selected physical aggression significantly more often than women (p less than .001). Using the binomial effect size display (BESD) to illustrate the magnitude of the sex difference, 69% of the men would be classified as physically aggressive (above the median), whereas only 31% of the women would be so classified. It was concluded that the Response Hierarchy consistently demonstrates sex differences among college students in retrospectively reported preference for choosing physical aggression versus other coping strategies as a response to hypothetical interpersonal conflict situations of adolescence.     

Psychological correlates of negative self-assessed health

The recent growth in the area now subsumed under the title health psychology can be seen to reflect real changes in the societal pre-occupation with health promotion. Established models within health psychology have tended to focus on the interface between the individual and the health care system. Moreover, as a consequence of employing the tripartite model of health, illness and sick-role behaviour as separate entities, research has tended to construct barriers between these behaviours. In is necessary to develop psychological models within health psychology rather than use the education model of the medical orthodoxy. This study explored the distinguishing features of a sub-group of women within the sample who were identified as having relatively negative self-assessed health. Data was obtained on their experience of health and illness, their involvement in health-related behaviours (HRB) and their health beliefs. It was shown that this group was more likely to be involved in damaging HRB, but involvement in positive HRB did not differ from the main sample. They tended to anticipate an improvement over time from their present health status which they felt had been influenced by their own behaviour and by their experience of motherhood.     

Sex differences in performance and hemispheric organization for a nonverbal auditory task.

Musically experienced and inexperienced men and women discriminated among fundamental-frequency contours presented either binaurally (i.e., same contour to both ears) or dichotically (i.e., different contours to each ear). On two separate occasions, males made significantly fewer errors than did females in the binaural condition, but not in the dichotic condition. Subjects with prior musical experience were superior to musically naive subjects in both conditions. The dichotic pitch task produced a left-ear advantage, which was unrelated to gender or musical experience. The results suggest that the male advantage on the binaural task reflects a sex difference in the coordination of the two hemispheres during conjoint processing of the same stimuli rather than a difference in the direction or degree of hemispheric specialization for these stimuli.     

The foreperiod effect revisited

This paper explores four factors which could be important in accounting for the discrepant results which have previously been obtained with respect to the effect of foreperiod duration on reaction time (RT). In some studies a clear effect of foreperiod duration on auditory RT has been found, in contrast to a recent finding that foreperiod duration affected visual RT but not auditory RT. By means of two experiments, the effects of practice, time-on-task, reaction task (a-reaction versus selective reaction) and signal intensity were studied. The latter variable appears to be the principal determinant of the discrepant results in that there is an interaction between signal intensity, foreperiod duration and modality. The results fit the hypothesis that signals beyond a given intensity exert an immediate arousing effect which counteracts the foreperiod effect.     

Inferences about the femininity of competent women and their implications for likability

Male (N=59) and female (N=60) college students were given a written protocol describing a competent, achievement-oriented female stimulus person (SP) with either a masculine or feminine pattern of vocational and avocational interests. Three groups were given a masculine-pattern protocol and one group was given a feminine-pattern one. They were then asked to rate the SP on likability in work and social settings, femininity, and a number of other personal attributes. Two groups given the masculine-pattern protocol were also supplied with the SP's responses to items from a “personality” test answered in a predominantly feminine (Masculine—Feminine SP) or masculine (Masculine-Masculine SP) direction. The remaining groups (Masculine-Neutral and Feminine-Neutral SPs) were given no additional information. In agreement with previous findings, the Masculine-Neutral SP was liked more in social settings than was the Feminine-Neutral one. It was hypothesized and confirmed that the Masculine-Neutral SP would be perceived as similar to the Masculine-Feminine SP in femininity and likability and that both these SPs would be judged to be higher on these characteristics than the Masculine-Masculine. Complex results were obtained from the ratings of other attributes. Overall, they indicated that the Masculine-Feminine SP, in whom femininity was explicitly suggested, received the weakest ratings on a series of achievement-related attributes and the Masculine-Neutral SP the strongest.     

Sensitivity to low doses of ethanol and pentobarbital in mice selected for sensitivity to hypnotic doses of ethanol.

These experiments assessed sensitivity to low doses of ethanol and pentobarbital in mice that had been selectively bred with respect to ethanol sleep time (the length of time an animal remains on its back following a hypnotic dose of ethanol). The hypothesis under investigation was that short-sleep (SS) mice might be more sensitive than long-sleep (LS) mice to excitatory effects produced by low doses of depressants. In support of this hypothesis SS mice were more active in an open-field test after ethanol than were LS mice. The lines did not differ in performance on a rotating-rod apparatus after these same doses of ethanol, suggesting that the difference in open-field activity was not attributable to a greater impairment of locomotor activity in LS mice. A similar difference in the open-field activity of the selected lines was observed with pentobarbital.
