A comparative analysis of the validity of several approaches to the scoring of the behavior of the preterm infant

A group of very low birthweight preterm infants (mean WEIGHT = 1193.6 g; mean gestational AGE = 31.1 weeks) were examined with the PREMIE. The PREMIE is a modification of the scoring system of the full term Brazelton Neonatal Behavioral Assessment (BNBAS) examination for use with preterm infants. Infants were assessed during the acute phase of cardio-respiratory illness (mean AGE = 7 days) and during the recovery phase (mean AGE = 22 days). Many modifications in procedure were required. Several analyses were performed to assess the redundancy and the comparative validity of the scoring systems of the PREMIE, the BNBAS, and the BNBAS + (the BNBAS plus a set of five additional preterm items). Results indicated that the three scoring systems were highly redundant, that they were equally related to physiologic and clinical variables, and that they were similar in their sensitivity to behavioral change and stability. Overall the results offered little in the way of differentiating among these three scoring systems with this group of infants, raising doubts about the need to use the PREMIE or other scoring systems like it for many research purposes.     

Infant attention to facial expressions and facial motion

Three-month-old infants were shown moving faces and still faces on videotape in a paired-comparison situation. Motion type was clearly specified, and facial expression and motion were separately varied. Infants saw a still face, internal motion on the face (i.e., motion of the internal features), and whole object (i.e., side-to-side) motion, each with happy and neutral expressions. Infants showed preference for expressions when the face was still and when it showed internal motion. Facial expression and facial motion were equally preferred, and both appeared to be salient dimensions of the face for three-month-old infants.     

Repetitive escape nightmares of refugees

Questionnaire responses of 38 Czechoslovak refugees indicated that 84.2% experienced, at least once, a nightmare about being back in their ex-homeland and trying to escape again. The escape nightmares were most frequent within the first 2 years after escape. A significant decrease in frequency was noted 4 years after escape and during the subsequent years.     

Content of waking life events and of nightmare themes

Examined the relationship of incidence of 3 types of nightmare themes to incidence of specific events listed in the Social Readjustment Rating Scale and in the Life Events Inventory. The former list of events was administered to 98 and the latter to 56 part-time college students. Information on nightmares' content was available for both samples. Events and nightmare themes were retrospectively reported for the last 6 mo. No significant relationships were found between specific types of nightmare content and specific events. Persons who experienced more events of the Life Events Inventory also reported more nightmare themes, however, similar relationship was not observed for events listed in the readjustment scale.     

Can Social Supports Be Engineered? An Example from the Army's Unit Manning System1

The purpose of the study was to examine variables which lead to the perception of instrumental social support among military wives. More specifically, we were interested in two factors: (a) the Unit Manning System, a method of deployment which keeps groups of soldiers and their families together for long periods of time; and (b) husbands' ranks. Both factors were found to be significant predictors of support in a previous study. Using a path analytic model, we demonstrated that being an officer's wife was related to perceived social support only indirectly through its influence on degree of participation in wives' group activities. Participation in the Unit Manning System also had only an indirect influence on social support. Reasons for these findings are discussed with reference to theories about coping and coping assistance.     

Verbal indicators of depression.

Speech content, voice quality, and temporal pacing of speech were evaluated for 11 well and 11 depressed women. Sadness was the dominant mood of the depressed women's speech, whereas happiness and mood neutrality characterized the well women's speech. The well women's tone of voice changed with the content of their speech. The well women spoke with a wide range of fundamental frequency, and the average fundamental frequency of their voices changed according to speech content. In contrast, the depressed women spoke with a narrow range of fundamental frequency, and the average fundamental frequency of their speech was unaffected by speech content. The depressed women spoke with longer pauses than the well women did. The results of this study contribute to the understanding of measures for assessing depression.     

The factor structure and criterion validity of the short form of the Eating Attitudes Test.

One of the more frequently used measures of eating disorders is the 40-item Eating Attitudes Test (EAT) developed by Garner and Garfinkel (1979). Although originally designed to diagnose anorexia nervosa, the test has recently been applied to nonclinical populations also. In this study, we examined psychometric and validity data for a short version of the scale, the EAT-26. Using a sample of 809 female soldiers in their late teens, results showed that the EAT-26 is reliable, the factor structure is different from that obtained in clinical groups, and the EAT-26 is significantly correlated with body image, weight, and diet.     

Al‐Dhimma: The non‐believers’ identity in Islam

The question as to the status of non‐Muslim minorities in Muslim states under an Islamic aegis has assumed importance once again in our times. The article argues that since dhimma status is secondary to the status of non‐believers, it is necessary that the theoretical basis of this latter relationship should be explored further. The article also points to the need of a fresh analytical understanding of the qur'anic term ‘the people of the Book’ and the possibilities of its wider application. The article reverts to the basic qur'anic distinction between din or faith and shir^ca and minhaj or code of conduct and way of life. The accommodative possibilities inherent in the distinction are briefly referred to.     

Auditory apparent motion in the free field: The effects of stimulus duration and separation

The effects of stimulus duration and spatial separation on the illusion of apparent motion in the auditory modality were examined. Two narrow-band noise sources (40 dB, A-weighted) were presented through speakers separated in space by 2.5°, 5°, or 100, centered about the subject’s midline. The duration of each stimulus was 5, 10, or 50 msec. On each trial, the sound pair was temporally separated by 1 of 10 interstimulus onset intervals (ISOIs): 0, 2, 4, 6, 8, 10, 15, 20, 50, or 70 msec. Five subjects were tested in nine trial blocks; each block represented a particular spatial-separation-duration combination. Within a trial block, each ISOI was presented 30 times each, in random order. Subjects were instructed to listen to the stimulus sequence and classify their perception of the sound into one of five categories: single sound, simultaneous sounds, continuous motion, broken motion, or successive sounds. Each subject was also required to identify the location of the first-occurring stimulus (left or right). The percentage of continuous-motion responses was significantly affected by the ISOI [F(9,36) = 5.67,p < .001], the duration × ISOI interaction [F(18,72) = 3.54,p < .0001], and the separation × duration × ISOI interaction [F(36,144) = 1.51,p < .05]. The results indicate that a minimum duration is required for the perception of auditory apparent motion. Little or no motion was reported at durations of 10 msec or less. At a duration of 50 msec, motion was reported most often for ISOIs of 20–50 msec. The effect of separation appeared to be limited to durations and-ISOIs during which little motion was perceived.     

Examining the Invariance of Holland's Vocational Interest Model across Gender

This study examines the structural invariance of Holland's (1973, 1985) vocational interest model across gender. Evidence of gender differences in the fit of Holland's model was sought by submitting 14 (7 male; 7 female) previously published Strong Interest Inventory (SII) General Occupational Themes (GOT) scale correlation matrices to multiple structural analytic techniques. Randomization tests of hypothesized order relations (Hubert Arabie, 1987) and single sample confirmatory factor analyses (CFA) indicated a moderate to strong correspondence between GOT data and Holland's circular order and circumplex models. Randomization tests of differences in model–data fit, and two-sample CFA indicated that these models are a no more or less accurate representation of the observed data for men than for women. Additional analyses aimed at identifying gender differences in the misfit of specific aspects of Holland's model also yielded no evidence of differential fit.
