Evaluating the Effectiveness of Premarital Prevention Programs: A Meta‐Analytic Review of Outcome Research

We present a comprehensive, meta‐analytic review and critical evaluation of outcome research pertaining to the effectiveness of premarital prevention programs. Results revealed that the mean effect size for premarital programs was .80, which means that the average person who participated in a premarital prevention program was significantly better off afterwards than 79% of people who did not participate. Stated differently, the average participant in a premarital program tends to experience about a 30% increase in measures of outcome success. Our findings suggest that premarital prevention programs are generally effective in producing immediate and short‐term gains in interpersonal skills and overall relationship quality and that these improvements are significantly better than nonintervention couples in these areas. However, because of a lack of extended follow‐up research, conclusions about long‐term effectiveness remain elusive. We propose implications for future research, education, and policy.     

Implications of a diagnosis of anorexia nervosa in a ballet school

Competitive pressures to achieve a slim body shape may be of importance in the etiology of eating disorders in ballet dancers. This study examines the presence of anorexia nervosa-like symptoms in a group of 49 female ballet students (mean age = 18.9 years, SD ± 1.9). All students were assessed for certain physical (weight and height) and psychological (Eating Attitude Test [EAT]) indices at the start of their academic training year. Thereafter, all subjects who presented with anorexia nervosa-like symptoms (EAT ≥ 30, and/or with current secondary amenorrhea or primary amenorrhea if aged 16 years or over) at the initial assessment, were invited for a semistructured interview (Morgan-Russel scales) to determine their diagnostic status. Another aim of the study was to assess the prognostic implications of a diagnosis of anorexia nervosa in this sample. All subjects previously interviewed were invited for a follow-up assessment at 10 months. Anorexia nervosa could be diagnosed in 2 students (4.1%), whilst another 4 students (8.2%) presented with “partial syndrome” anorexia nervosa. All diagnosed students managed to complete their academic training year. The development and implications of a diagnosis of anorexia nervosa in the ballet students are discussed.     

Polyclonal B-lymphocyte stimulation in human malaria and its association with ongoing parasitemia

To study the polyclonal B-lymphocyte stimulation or activation (PBA) phenomenon in human malaria, the numbers of immunoglobulin (G, A, and M)-secreting cells in the peripheral blood, serum levels of immunoglobulins, and the presence of antibodies directed against the DNA-autoantigen were evaluated in Plasmodium falciparum- and P. vivax-infected individuals. Individuals chronically exposed to the risk of infection or non-immune subjects who contracted malaria during first visits to endemic areas were studied. Numbers of immunoglobulin-secreting cells (IgSC) were increased dependent upon ongoing parasitemia. Levels of IgG and the anti-DNA activity were also augmented in malarious individuals from the endemic area. Study of the kinetics of PBA done in treated patients showed that PBA decreased during treatment and disappeared 5-15 days after the start of chemotherapy.     

Cognitive consequences of early phase of literacy.

The effect of the degree of illiteracy (complete or incomplete) on phonological skills, verbal and visual memory and visuospatial skills is examined in 97 normal Brazilian adults who considered themselves illiterate, and 41 Brazilian school children aged 7 to 8 years, either nonreaders or beginning readers. Similar literacy effects were observed in children and in adults. Tasks involving phonological awareness and visual recognition memory of nonsense figures distinguish the best nonreaders and beginning readers. Children performed better than adults at oral repetition of short items and figure recall, and adults better than children at semantic verbal fluency, digit span, and word list recall. A principal component analysis of the correlations between tasks showed that phonological awareness/reading, phonological memory/oral repetition, and semantic verbal memory/fluency tasks, generated different components. The respective role of culturally based preschool activities and literacy on the cognitive functions that are explored in this study is discussed.     

Investigative profile of patients with a profound sensorineural hearing loss

Two hundred and eighty five patients presenting with profound bilateral sensorineural hearing loss from 1987 to 1989, were subjected to a detailed history, pure tone audiogram, aided audiogram, Brain Stem Evoked Response Audiometry, Electrocochleography, Cochlear Nerve Test, and Tomograms of the temporal bones. All the data collected was subsequently analysed.     

Copper radionuclides and radiopharmaceuticals in nuclear medicine

The chemistry, radiochemistry, radiobiology, and radiopharmacology of radiopharmaceuticals containing copper radionuclides are reviewed. Copper radionuclides offer application in positron emission tomography, targeted radiotherapy, and single photon imaging. The chemistry of copper is relatively simple and well-suited to radiopharmaceutical application. Current radiopharmaceuticals include biomolecules labelled via bifunctional chelators primarily based on cyclic polyaminocarboxylates and polyamines, and pyruvaldehyde-bis(N⁴-methylthiosemicarbazone) (PTSM) and its analogues. The chemistry of copper, of which only a fraction has yet been exploited, is likely to be applied more fully in the future.
