Reliability and validity of the Beck depression inventory--II with adolescent psychiatric inpatients

This investigation was conducted to validate the Beck Depression Inventory--II (BDI-II; A. T. Beck, R. A. Steer, & G. K. Brown, 1996) in samples of adolescent psychiatric inpatients. The sample in each substudy was primarily Caucasian. In Study 1, expert raters (N=7) and adolescent psychiatric inpatients (N=13) evaluated the BDI-II items to assess content validity. In Study 2, confirmatory factor analyses of several first-order solutions failed to provide adequate fit estimates to data for 205 boys, 203 girls, and the combined sample. Exploratory factor analyses identified new item-factor solutions. Reliability estimates were good (range =.72 to.91) for the BDI-II total and scale scores. In Study 3 (N=161 boys and 158 girls from Study 2), preliminary evidence for estimates of concurrent, convergent, and discriminant validity were established for the BDI-II.     

Effect of intensive training on auditory processing and reading skills

This study assessed the ability of seven children to accurately judge relative durations of auditory and visual stimuli before and after participation in a language remediation program. The goal of the intervention program is to improve the children's ability to detect and identify rapidly changing auditory stimuli, and thereby improve their language-related skills. Children showed improved accuracy on a test of auditory duration judgement following the intervention without analogous improvements in the visual domain, supporting the assertion that intensive training with modified speech improves auditory temporal discrimination. However, these improvements did not generalize to reading skills, as assessed by standard measures of phonological awareness and non-word reading.     

Stressor exposure produces long-term reductions in antigen-specific T and B cell responses

Exposure to an acute laboratory stressor at the time of keyhole limpet hemocyanin (KLH) immunization results in a long-term suppression in circulating anti-KLH antibody. The mechanism for the stress-induced reduction in anti-KLH immunoglobulin (Ig) remains unknown. Given that the generation of anti-KLH antibody requires T cell help, we hypothesize that stress reduces the proliferation of anti-KLH T cells, thus leading to a reduction in anti-KLH antibody. The present studies examined the effect of tail shock stress (100, 1.6 mA, 5-s, 60 s ITI) on the KLH specific T cell response. Fischer F344 rats were immunized either intraperitoneally (i.p.) or subcutaneously (s.c.) at the base of the tail with 200 microg KLH, and exposed to inescapable tail shock (IS) or remained in their home cages (HCC). T cell proliferation after KLH restimulation, but not ConA, was markedly suppressed in IS animals in both the spleen after i.p. immunization and the draining lymph nodes after s.c. immunization. Other secondary lymphoid cells did not differ in their proliferative capacity. Anti-KLH IgG, IgG1 and IgG2a, but not anti-KLH IgM serum levels were significantly suppressed. These data support the conclusion that stress suppresses the generation of antigen specific T cells. In addition, the methods employed in the current study allow the isolation of the site of the acquired T cell immune response, making it possible to further elucidate the cellular mechanisms that contribute to stress-induced modulation of the antigen-specific acquired immune response.     

Two-component theory of the suffix effect: contrary findings

The suffix effect is the reduction in the recallability of the last few items of a just-spoken list caused by appending a nominally irrelevant item, or suffix. The effect is widely assumed to comprise a "structural" terminal component, affecting just the last item, and a strategy-sensitive preterminal component. In a series of 8 experiments, the authors fail to replicate any of a variety of findings widely cited as the empirical basis for this 2-component theory. The authors also question the support that earlier findings provide for the theory, even if they had proved replicable. They attribute the entire suffix effect to the grouping of the suffix with the list items.     

Effects of Interspersing Additional Brief Math Problems on Student Performance and Perception of Math Assignments: Getting Students to Prefer to Do More Work

Three experiments were conducted to assess the effects of the interspersing procedure on students' mathematics performance, perceptions of mathematics assignments, and preference for mathematics assignments when more work was added. In Experiment I, college students worked computation problems from two assignments. The control assignment contained 15 three-digit by two-digit problems (3 × 2) and the experimental assignments contained 18 3 × 2 problems and 6 additional interspersed one-digit by one-digit problems (1 × 1). Students then rated the assignments and chose one for homework. Results showed significantly more students preferred (i.e., chose it for homework) the experimental assignment with the additional target (i.e., 3 × 2) and interspersed problems. Furthermore, significantly more students rated this experiment as requiring less effort and being less difficult. Moreover, students' mathematics performance was not affected by the procedure. Experiment II strengthened the internal validity by showing that students did not prefer the experimental assignment because it contained more target problems. Experiment III showed that the interspersing procedure was not powerful enough to extend findings beyond the 20% level (i.e., 40 and 60% more conditions). Results showed how the interspersing procedure could be used to encourage students to choose to do more target computation tasks. Discussion focuses on the applied value of the interspersing procedure and plausible causal mechanisms that may account for current and past findings related to student choice and interspersing brief tasks.     

Whole-school guidance?

The present status of guidance as a whole-school feature of the British secondary school is explored. The ingredients and issues in the development of such an approach are clarified. The status and terminology of 'cross-curricular' initiatives are examined. The need for re-asserting the rationales for guidance within an overarching whole-school view of pupils' personal-social development is suggested. Finally, a new window of opportunity for schools is identified in recent developments regarding the National Curriculum in England.     

The Individual Psychology of Alfred Adler: Toward an Adlerian vocational theory

Within the past couple of decades, the Individual Psychology of Alfred Adler has become increasingly popular among consultants, educators, and psychotherapists alike. The approach also has gained the attention of several vocational researchers, and some vocational investigations on Adler's theory have appeared. Unfortunately, such empirical studies have been all too few, seemingly because no articulated framework exists of an Adlerian vocational theory. In this article, an Adlerian vocational theory is proposed. Specific hypotheses and corollaries, each derived from the substantive base of Individual Psychology, are presented and explained.     

Speech-like coding of pictures in short-term memory

Memory span for pictures of common objects and for the names of these objects was examined as a function of three speech-related variables. Both picture span and name span were found to be influenced by the phonological similarity (Experiment 1) and the length (Experiment 2) of the names, as well as by the subject’s engaging in “irrelevant” vocalization during item presentation (Experiment 3). Moreover, for each variable the effect was in the same direction and of comparable magnitude for the two types of items. Experiments 4-6 replicated these findings with the procedure modified such that the retention of order information was not required. It is concluded that under the present conditions, there is a substantial functional equivalence between short-term memory for readily nameable pictures and for words and that this equivalence may be thought of as due to mediation by a common, “speech-like” code.     

Some thoughts about a scientist-practitioner approach to assessment training in counselling psychology

Training effective scientist-practitioners has long been an issue of concern in counselling psychology. In a recent paper, Friedlander (1992) developed a useful prototype to foster science-practice integration in a counselling seminar. Drawing on Friedlander's prototype, the question of “how to foster science-practice integration in assessment” is considered. Some assessment reading lists and class exercises designed to illustrate such integration are proposed. These teaching materials are presented: (a) in hopes that they might prove useful for some assessment instruction purposes; and (6) in hopes that they might stimulate further thinking about how to best foster science-practice integration in counselling psychology assessment courses.     

The protective role of social network factors during the COVID-19 pandemic in the United States

The present study examined the relationship between COVID-19 threat perception, isolating health precautions, and loneliness. As a test of the stress-buffering hypothesis (Cohen & Wills, 1985), this study also examined if social network factors representing various aspects of social support moderated, or weakened, the relationship between threat perception, isolating health precautions, and loneliness. Participants (N = 1149) provided information about themselves, as well as 15 other people they know via an online survey. We found that structural and compositional social network factors, density, number of close alters, network threat perception, network covid cautiousness and number of vaccinated alters all negatively related to loneliness. Further, using moderated mediation analyses, we found that network threat perception and network covid cautiousness moderated the indirect relationship between threat perception and loneliness through precautions. At high levels of these factors, the mediation was less likely to be significant suggesting that the social network factors may buffer people from the loneliness that sometimes comes with engaging in isolating health precautions in response to the perceived threat of COVID-19.
