Identifying Youth at Risk for Treatment Failure in Outpatient Community Mental Health Services

We developed predicted change trajectories and a warning system designed to identify psychotherapy cases at risk for treatment failure as observed in archival Youth Outcome Questionnaire data (parent/guardian-report) from 363 children and adolescents (ages 4–17) served in an outpatient community mental health system. We used multilevel modeling procedures to develop models of predicted change based on demographic information. Controlling for the effects of age on intercept, no other variables were significant in the model. The warning system we created from half of the sample (n = 181) correctly identified 71% of treatment failures in the other half of the sample (n = 182), defined as cases whose symptoms were significantly higher at the end of treatment compared to symptoms at intake. As over half of youth cases in this usual care setting did not demonstrate reliable improvement in symptoms, these results further emphasize the value of patient-focused research in monitoring patient progress and prompting changes in the treatment approach if suitable progress is not observed.     

The Eight Trigrams of the Chinese I Ching and the Eight Primary Emotions

Durkheim and Mauss, in Primitive Classification , concluded that the emotions play a causal role in the history of dual symbolic classification systems, but could not test this intuitive speculation because they saw a classification of the emotions as impossible. In this paper a portion of Plutchik's psychoevolutionary model of the primary emotions are assumed to be valid and are then investigated through analysis of one of their three case studies of primitive classification, that of classification in ancient China, where their emphasis was on the eight "trigrams" or "powers" that they saw arranged in a "divinatory compass." The trigrams are three-line components of the "hexagrams," the six-line figures that are interpreted as master signs in I Ching divination rituals. Using Plutchik's psychoevolutionary classification of the emotions as a basis of comparison, especially his model of the primary emotions as adaptive reactions to the positive and negative experiences of four existential problems – identity, temporality/reproduction, hierarchy, and territoriality – it is found that both trigrams and primary emotions exist as four pairs of opposites. The eight trigrams and eight primary emotions similarly can be seen as adaptive reactions to the four basic problems of life. Through structural analysis, correspondences between the trigrams and the primary emotions are developed, the result being that the primary emotions are structurally isomorphic and very close in first meanings to the primary attributes of the trigrams. Implications of this isomorphism of structure for the development of a social psychology of the emotions are discussed.     

Genetic Influence Helps Explain Variation in Human Fertility: Evidence From Recent Behavioral and Molecular Genetic Studies

To search for genetic influence on human fertility differentials appears inconsistent with past empirical research and prior interpretations of Fisher's fundamental theorem of natural selection. We discuss Fisher's theorem and give reasons why genetic influences may indeed account for individual differences in human fertility. We review recent empirical studies showing genetic influence on variance in fertility outcomes and precursors to fertility. Further, some of the genetic variance underlying fertility outcomes overlaps with that underlying fertility precursors. Findings from different cultures, different times, different levels of data, and both behavioral and molecular genetic designs lead to the same conclusion: Fertility differentials are genetically influenced, and at least part of the influence derives from behavioral precursors that are under volitional control, which are themselves genetically mediated.     

Cognitive bias and irrational belief as predictors of avoidance

Cognitive bias, i.e. overestimates of subjective probability and cost of catastrophic events, and irrational belief were explored as predictors of avoidance. Three groups-anxiety disordered clients, a mixed group of clinic outpatients, and normals--were administered several self-report inventories. Multiple regression analyses were used to investigate a modified version of the Agoraphobic Cognitions Questionnaire, the Belief Scale, and the Body Sensations Questionnaire as predictors of avoidance, as measured by the Mobility Inventory. It was hypothesized that frequency x probability x cost of catastrophic cognitions (and the occurrence of the events they represent) would be a better predictor of avoidance than frequency alone. It was also hypothesized that irrational thinking would be a significant predictor of avoidance. The results generally supported the hypotheses, with subjective probability emerging as a particularly potent predictor of avoidance. Theoretical and clinical implications are discussed.     

Measuring activity using actometers: A methodological study

Actometers are men's self-winding mechanical wristwatches that have been modified such that they measure activity rather than time. Actometers can be used to obtain longitudinal naturalistic measures of activity concerning a variety of clinical populations. However, no systematic methodological research has been conducted with regard to the site of attachment and the duration of measurement necessary to ensure valid results. This article presents the results of a methodological study designed to answer these questions. The mean activity levels associated with the Left Wrist and Ankle were nearly equal to those associated with the Right Wrist and Ankle. The Ankle readings were substantially greater than the Wrist readings because the subjects' legs were longer than their arms. The data from Week 2 were the same as those from Week 1.     

Preliminary psychometric evaluation of a standardized clinical family interview

Though multiple task interviews are often preferable for family interaction research, clinical-style interviews have a rôle to play. The 'Standardized Clinical Family Interview', whose development, structure and mode of administration have been described in an earlier paper, is designed to elicit family interaction in a clinically relevant fashion. A series of studies which evaluated the reliability, sensitivity, validity and acceptability of this instrument is now provided. The results suggest that the SCFI is useful and deserves further study; however, interviewer training is a major task.     

Use of speech-modulated noise adds strong “bottom-up” cues for phonemic restoration

When deleted segments of speech are replaced by extraneous sounds rather than silence, the missing speech fragments may be perceptually restored and intelligibility improved. This phonemic restoration (PhR) effect has been used to measure various aspects of speech processing, with deleted portions of speech typically being replaced by stochastic noise. However, several recent studies of PhR have used speech-modulated noise, which may provide amplitude-envelope cues concerning the replaced speech. The present study compared the effects upon intelligibility of replacing regularly spaced portions of speech with stochastic (white) noise versus speech-modulated noise. In Experiment 1, filling periodic gaps in sentences with noise modulated by the amplitude envelope of the deleted speech fragments produced twice the intelligibility increase obtained with interpolated stochastic noise. Moreover, when lists of isolated monosyllables were interrupted in Experiment 2, interpolation of speech-modulated noise increased intelligibility whereas stochastic noise reduced intelligibility. The augmentation of PhR produced by modulated noise appeared without practice, suggesting that speech processing normally involves not only a narrowband analysis of spectral information but also a wideband integration of amplitude levels across critical bands. This is of considerable theoretical interest, but it also suggests that since PhRs produced by speech-modulated noise utilize potent bottom-up cues provided by the noise, they differ from the PhRs produced by extraneous sounds, such as coughs and stochastic noise.     

Spectral redundancy: Intelligibility of sentences heard through narrow spectral slits

The intelligibility of word lists subjected to various types of spectral filtering has been studied extensively. Although words used for communication are usually present in sentences rather than lists, there has been no systematic report of the intelligibility of lexical components of narrowband sentences. In the present study, we found that surprisingly little spectral information is required to identify component words when sentences are heard through narrow spectral slits. Four hundred twenty listeners (21 groups of 20 subjects) were each presented with 100 bandpass filtered CID ( “everyday speech ”) sentences; separate groups received center frequencies of 370, 530, 750, 1100, 1500, 2100, 3000, 4200, and 6000 Hz at 70 dBA SPL. In Experiment 1, intelligibility of single 1/3-octave bands with steep filter slopes (96 dB/octave) averaged more than 95% for sentences centered at 1100, 1500, and 2100 Hz. In Experiment 2, we used the same center frequencies with extremely narrow bands (slopes of 115 dB/octave intersecting at the center frequency, resulting in a nominal bandwidth of l/20 octave). Despite the severe spectral tilt for all frequencies of this impoverished spectrum, intelligibility remained relatively high for most bands, with the greatest intelligibility (77%) at 1500 Hz. In Experiments 1 and 2, the bands centered at 370 and 6000 Hz provided little useful information when presented individually, but in each experiment they interacted synergistically when combined. The present findings demonstrate the adaptive flexibility of mechanisms used for speech perception and are discussed in the context of the LAME model of opportunistic multilevel processing.
