Discriminant Function Analyses

MMPI profiles, including L, K, and F validity scale data, were examined for 40 hospitalized psychiatric patients, for whom diagnoses from both psychologists and physicians were available. Comparison of diagnostic patterns of the same patients, especially for diagnoses of Personality Disorders and Schizophrenics, showed relatively little agreement between disciplines. Discriminant function analyses showed also that each discipline weighted MMPI scales differently in determining diagnosis, even though the scale profiles for each patient in the sample were essentially identical. The MMPI seemingly played a nonsignificant role in determining a set of inconsistently applied diagnoses.

Discriminant Function Analyses

This study was designed to investigate the comparability of the original MMPI (1950) and the MMPI-2 (1989) with a psychiatric patient population. 34 male and 3 female patients, shortly after admission to one of two acute psychiatry units, completed the old and revised versions of the MMPI. Paired t tests indicated but scant differences for raw scores, while many more differences were found among T scores for validity, clinical, and supplemental scales. Analyses, however, showed all scales on the two forms to be highly correlated. Analysis of the high-point and two-point codes across the two administrations also showed relative stability, although the proportion of Scales 2 (Depression) and 8 (Schizophrenia) decreased, while those for Scales 6 (Paranoia) and 7 (Psychasthenia) increased markedly in the MMPI-2 protocols. Examination of each version's discriminability among mood- and thought-disordered subsamples suggested that the MMPI provides slightly better delineation between diagnostic classes. Discriminant function analyses showed that there were essentially no differences between the two forms in the accurate classification of clinical and nonclinical groups. The findings reported here provide support for the MMPI-2; despite modification, the newer form retains the advantages of the original MMPI. Differences found here may be unique to psychiatric patients and their patterns of MMPI/MMPI-2 equivalence and may not generalize to other special populations.

Affective Psychoses

SynopsisThe excretion of dimethyltryptamine (DMT) was studied amongst 122 recently admitted psychiatric patients and 20 normal subjects. DMT was detected in the urine of 47% of those diagnosed by their psychiatrists as schizophrenic, 38% of those with other non-affective psychoses, 13% of those with affective psychoses, 19% of those with neurotic and personality disorders and 5% of normal subjects. Ninety-nine patients were interviewed in a semi-standardized fashion, and also categorized according to a variety of operational definitions of the psychoses. The operational definitions failed to reveal any group significantly more correlated with urinary DMT than a hospital diagnosis of schizophrenia, but a discriminant function analysis of symptomatology could be used to define a group of 21 patients of whom 15 (71%) excreted detectable DMT. There was a general relationship between psychotic symptoms and urinary DMT, but specifically schizophrenic symptoms did not appear to be major determinants of DMT excretion.

Degree Of Severity

This study explores differences in the use of music in everyday life among diagnostic groups of a psychiatric population (n = 180) in reference to a group of healthy subjects (n = 430). The results indicate that patients with mental disorders use music more for emotion modulation than healthy controls. In particular, patients with substance abuse and those with personality disorders used music mainly for cognitive problem solving and the reduction of negative activation, whereas patients with substance abuse in addition used music not often to stimulate themselves positively. Patients suffering from schizophrenia and personality disorders more often applied music for relaxation than the subjects of the reference group. Furthermore, the degree of severity of the psychiatric disorder correlated with the increased use of music for emotion modulation, i.e., for relaxation and cognitive problem solving. Thus, the results demonstrate an increased use of music for emotion modulation in patients with mental disorders in association with the severity of the disorder.

The distribution scores on the Socialization (So) scale of the California Psychologial Inventory was examined in a series of 83 admissions to a general hospital psychiatric service. The series was divided into groups of low and high scorers (Low So and High So). Low So scorers were younger than high scorers and had a raised mean Neuroticism score. A strong association was found between So scores and the quality of parental care which patients reported receiving from their fathers. Other parental attributes are reported. Patients with a clinical diagnosis of personality disorder were found in the Low So, but not the High So group.

Aim: Landmark-based truss network system was applied to examine the morphometric and meristic differences among four different populaces of Macrognathus aculeatus namely; Dhakuriabeel, Jashore (DBJ); Arial Kha River, Madaripur (AKRM); Nabaganga River, Jhenaidah (NRJ); Kopotakkha River, Jashore (KRJ) in Bangladesh. Methodology: Completely 80 samples of M. aculeatus were collected (20 individuals from each population) for this study. Six meristic characters, 6 morphometric characters and 15 truss-based morphometric characters were measured for one-way analysis of variance (ANOVA) and Tukey-HSD post hoc test. Discriminant function analyses were also performed by using morphometric and truss-based morphometric characters to detect potential characters responsible for population separation. Results: Completely 80 samples of M. aculeatus were collected (20 individuals from each population) for this study. Six meristic characters, 6 morphometric characters and 15 truss-based morphometric characters were measured for one-way analysis of variance (ANOVA) and Tukey-HSD post hoc test. Discriminant function analyses were also performed by using morphometric and truss-based morphometric characters to detect potential characters responsible for population separation. Interpretation: The baseline information derived from the present study would be useful for appropriate conservation of M. aculeatus populations as well as for the researchers for further investigation.

Discriminant Function Analyses

In a study of Middle Preclassic (Conchas phase) ceramics from the site of La Blanca, Love (1989) derived a sequence of four subphases. Here, the focus is on 431 prismatic obsidian blades excavated from the same deposits in order to discern if patterns of change can be discovered in this lithic industry. For each blade, recorded attributes describe blade dimensions and edge wear, as observed through low-power microscopy. Chronological controls were set by ceramic associations. Through the sequence, blades became smaller and more fragmentary, due, we hypothesized, to an increasing scarcity of obsidian. As predicted from these trends, we found that wear patterns became more pronounced through time, and use of a bipolar technology became increasingly important for removing (rejuvenating) worn lateral edges. A definite obsidian-blade sequence emerged, which was investigated through linear discriminant-function analyses.

Many problems are associated with the measurement of athletes in contemporary sport psychology. There is, for example, a dearth of valid and reliable tests to assess the many and diverse behaviors of players. The purpose of this investigation was to attempt to validate Zuckerman's sensation seeking scale (SSS V) using high- and low-risk sport participants. The SSS (Form V) was administered to male hang gliders (n = 33), automobile racers (n = 22), and intercollegiate bowlers (n = 25). It was hypothesized that the high-risk athletes (hang gliders and auto racers) would score significantly higher (.05 level) than the low-risk sport participants (bowlers) in total sensation seeking score and on the four subscales of Zuckerman's test. Stepwise multiple discriminant function analyses found that except for thrill and adventure seeking and disinhibition subscales, the above hypotheses were tenable. Thus, it was concluded that support exists for Zuckerman's SSS (Form V) as a measure of sensation seeking among male athletes.

Discriminant Function Analyses

In songbirds, male song is an acoustic signal used to attract mates and defend territories. Typically, song is an acoustically complex signal; however, the fee-bee song of the black-capped chickadee is relatively simple. Despite this relative simplicity, two previous studies (Christie et al., 2004b; Hoeschele et al., 2010) found acoustic features within the fee-bee song that contain information regarding an individual’s dominance rank; however each of these studies reported a different dominance-related acoustic cue. Specifically, the relative amplitude of the two notes differed between the songs of dominant and subordinate males from northern British Columbia, while the interval pitch ratio differed between the songs of dominant and subordinate males from eastern Ontario. In the current study, we examined six acoustic features within songs from both of the chickadee populations (northern British Columbia and eastern Ontario) examined in these previous studies and used bioacoustic analyses and discriminant function analyses to determine whether there is a consistent dominance-related acoustic cue across both, or in each of these populations. Consistent with the previous findings, the current results indicate that relative amplitude differs based on dominance status in the songs from British Columbia; however, our results failed to reach significance with songs from Ontario. These results suggest that acoustic cues that signal a male’s dominance in this species vary with geographic location. Furthermore, examining songs from these two locations and one additional location in northern British Columbia, we found that discriminant function analyses could correctly classify songs based on geographic location. Considering the broad extent of the species’ range, black-capped chickadee song is considered relatively invariant; however, our results suggest that there is geographic variation in songs, although the differences are subtle compared to geographic song variation in other species.
