The need for inpatient palliative care facilities for noncancer patients in the Thames Valley.

Inpatient facilities in palliative care units are generally considered to be mainly for cancer patients. We present and discuss the results of a survey that attempted to estimate the number of noncancer patients requiring inpatient palliative care. Questionnaires sent to all general practices in the Thames Valley area asked about the diagnosis and the number of bed-days that would have been required for each noncancer patient in the practice dying in the last year or still in their care. The replies suggest that about 11 noncancer patients per practice per year were in need of respite or continuing care. For the Thames Valley area this would amount to at least 66,000 bed-days per year for noncancer patients, compared with the current provision, mainly for cancer patients, of about 40,000 bed-days per year. The diagnoses involved and the reasons why our figures may overestimate need, are discussed. There can be no doubt that, if the need is to be met, current facilities will be inadequate and additional beds and services will be required.

The relation of mothers' controlling vocalizations to children's intrinsic motivation.

Twenty-six mother-child dyads played together in a laboratory setting. Play sessions were surreptitiously videotaped (with mothers' permission), and each maternal vocalization was transcribed and coded, first into 1 of 24 categories and then ipso facto into one of three supercategories--namely, controlling, autonomy supportive, and neutral. The degree of mothers' controllingness was calculated as the percentage of vocalizations coded as controlling. This index was correlated with the intrinsic motivation of their 6- or 7-year-old children, as assessed primarily by the free-choice behavioral measure and secondarily by a child self-report measure of interest and liking for the task. Both correlations were significantly negative, thereby suggesting that the robust laboratory findings of a negative relation between controlling contexts and individuals' intrinsic motivation are directly generalizable to the domain of parenting. Results are discussed in terms of the processes that undermine intrinsic motivation and the means through which parental controllingness is communicated.

Pure tone audiograms from hearing-impaired children. II. Predicting speech-hearing from the audiogram.

Pure tone audiograms and speech audiograms using sentence lists were obtained from 150 8-16-year-old children with pure tone hearing losses ranging from mild to severe. Most of the hearing impairments were cochlear in origin. Three 'speech-hearing' measures were selected from the speech audiograms, and it was shown that the correlation coefficients between two of these and the pure tone hearing thresholds were roughly in agreement with figures from previous studies of adults = 0.882 for Speech Reception Threshold and 0.533 for Discrimination Score. In addition, a correlation of 0.329 was found between the slope of the speech audiogram and pure tone thresholds. The strength of different summaries of the pure tone audiogram for predicting the various speech-hearing measures were compared. It was found that although the traditional summaries did quite well, their relative strengths varied according to the speech-hearing measure under consideration. The best summary predictors for all the speech-hearing measures were, either alone or in combination, two indices which have been proposed recently by the present authors, and which measure both the degree of pure tone hearing loss and the slope of the pure tone audiogram. However, the gains in predictive strength achieved with these indices were small.

Pure tone audiograms from hearing-impaired children. I. A statistical approach to summarizing audiogram information.

Principal component analyses of the better-ear pure-tone audiograms from 201 hearing-impaired children are reported. The analyses show that two components, one measuring degree of hearing loss, the other the slope of the audiogram, account for 86% of the total variability. Two indices are proposed which correspond to the two components, but which have numerically simple coefficients and which, unlike the raw components, are perfectly "clean" measures of the two variables. Since these indices, 11 and 12, still account for 84% of the total audiogram variability, it is suggested that they may provide a quantitative basis for summarizing pure tone audiograms for general use.
