The Importance of Establishing Reliability and Validity of Assessment Instruments for Mental Health Problems: an Example from Somali Children and Adolescents Living in Three Refugee Camps in Ethiopia

Assessing mental health problems cross-culturally for children exposed to war and violence presents a number of unique challenges. One of the most important issues is the lack of validated symptom measures to assess these problems. The present study sought to evaluate the psychometric properties of two measures to assess mental health problems: the Achenbach Youth Self-Report and the Child Posttraumatic Stress Disorder Symptom Scale. We conducted a validity study in three refugee camps in Eastern Ethiopia in the outskirts of Jijiga, the capital of the Somali region. A total of 147 child and caregiver pairs were assessed, and scores obtained were submitted to rigorous psychometric evaluation. Excellent internal consistency reliability was obtained for symptom measures for children and their caregivers. Validation of study instruments based on local case definitions was obtained for the caregivers but not consistently for the children. Sensitivity and specificity of study measures were generally low, indicating that these scales would not perform adequately as screening instruments. Combined test–retest and inter-rater reliability was low for all scales. This study illustrates the need for validation and testing of existing measures cross-culturally. Methodological implications for future cross-cultural research studies in low- and middle-income countries are discussed.     

Maxillary suture obliteration: aging the human skeleton based on intact or fragmentary maxilla

Obliteration of the four sutures of the bony palate is examined to determine its value as an age indicator. Thirty-six maxillae from a predominately white series representing both sexes and a wide variety of ages are studied. It is concluded that the amount of obliteration of these sutures is useful in estimating general biological age.     

Archaeology, science and forensic anthropology: a tribute to Dr T. Dale Stewart

The name, T. Dale Stewart is synonymous with physical anthropology. To many members of the physical anthropology section, particularly those born in the latter half of this century, he is perhaps best known for his 1979 Essentials of Forensic Anthropology. Without a doubt, much of the foundation of this discipline rests upon his teachings and influence. Few knew him in the capacity that William M. Bass did, as T. Dale Stewart was a member of Bass doctoral committee. Bass was greatly influenced during the time he spent working with Dr. Stewart in the 1950's and the instruction and guidance Stewart instilled in Bass has and will continue to be passed on to subsequent generations. Research was Dale Stewart's main emphasis and he succeeded in demonstrating the value of investigation and how results were crucial in explaining many of the processes manifest on skeletal material. Clearly his hypothesis-based approach became essential to skeletal biology and numerous procedures and methods employed in the field are synonymous with the teachings of Dr. T. Dale Stewart. By reflecting on several recently completed interdisciplinary research projects, the far-reaching impact of his knowledge and instruction can be demonstrated.     

Time since death and decomposition of the human body: variables and observations in case and experimental field studies

Much of the difficulty in determining the time since death stems from the lack of systematic observation and research on the decomposition rate of the human body. Continuing studies conducted at the University of Tennessee, Knoxville, provide useful information on the impact of carrion insect activity, ambient temperature, rainfall, clothing, burial and depth, carnivores, bodily trauma, body weight, and the surface with which the body is in contact. This paper reports findings and observations accumulated during eight years of research and case studies that may clarify some of the questions concerning bodily decay.     

<Emphasis Type="Italic">Liberellas</Emphasis> Versus <Emphasis Type="Italic">Konservatives</Emphasis>: Social Status,Ideology, and Birth Names in the United States

Despite much public speculation, there is little scholarly research on whether or how ideology shapes American consumer behavior. Borrowing from previous studies, we theorize that ideology is associated with different forms of taste and conspicuous consumption: liberals are more drawn to indicators of “cultural capital” while conservatives favor more explicit signs of “economic capital”. These ideas are tested using birth certificate, U.S. Census, and voting records from California in 2004. We find strong differences in birth naming practices related to race, economic status, and ideology. Although higher status mothers of all races favor more popular birth names, higher status, white liberal mothers more often choose uncommon, culturally obscure birth names. White liberals also favor birth names with “softer, feminine” sounds while conservatives favor names with “harder, masculine” phonemes. These findings have significant implications for both studies of consumption and debates about ideology and political fragmentation in the United States.     

Is there universality in the full range model of leadership?

Universality implies that the relations between attributes of the person and performance as a leader are a constant across situations. It also implies that similar concepts and behaviors associated with leadership can be relevant everywhere. It is a difficult position to maintain. Nevertheless, this lead article contends that a model of transformational and transactional leadership has some degree of universality. The article describes the elements of the model and summarizes the support for these elements which derives from research initiated in the United States. Three corollaries are discussed with supportive evidence gathered in studies conducted in India, Italy, Canada, New Zealand, Japan, Singapore, Sweden and elsewhere to document the universality of transactional and transformational leadership. We conclude that although this model of leadership may require adjustments and fine-tuning as we move across cultures, particularly into non-Western cultures, overall, it holds up as having considerable universal potential.     

Cremation weights in east Tennessee

In spite of increasing number of cremations in the U.S., little is known about weights of cremated remains. This research was undertaken in order to add to the limited literature on cremains weights and to explore variation. Weights of cremated remains were obtained from the East Tennessee Crematorium. The sample consists of 151 males and 155 females. Age, sex, and race were obtained for each individual. Males are about 1000 g heavier than females. Both sexes lose weight with age, but females lose weight at about twice the rate of males. East Tennessee cremation weights were compared with those from Florida reported by Warren and Maples, and those from Southern California reported by Sonek. East Tennessee results were also compared with an earlier study on ash weight of anatomical human skeletons carried out by Trotter and Hixon. East Tennessee cremations weigh about 500 g more than the samples from Florida and California, and about the same as the earlier anatomical samples. We hypothesize that variation reflects variation in body weight and activity. This variation must be taken into account when cremation weights are at issue.     

Maxillary suture obliteration: a visual method for estimating skeletal age.

The purpose of this study was to develop a method of estimating the age of an individual based on obliteration of the four maxillary (palatal) sutures. A sample of 186 individuals of known age, race, and sex were examined. It was found that males of both races (black and white) exhibit more suture obliteration than females at the same age. During the early adult years, maxillary suture obliteration progresses at nearly the same rate in both sexes; however, the age of old individuals may be greatly overestimated using this method. Although this method cannot be used for exact estimates of individual age, it is valuable in establishing the age range, sorting commingled remains, and estimating skeletal age when only the maxilla is present.     

Time since death determinations of human cadavers using soil solution.

This study was conducted to collect data on specific volatile fatty acids (produced from soft tissue decomposition) and various anions and cations (liberated from soft tissue and bone), deposited in soil solution underneath decomposing human cadavers as an aid in determining the "time since death." Seven nude subjects (two black males, a white female and four white males) were placed within a decay research facility at various times of the year and allowed to decompose naturally. Data were amassed every three days in the spring and summer, and weekly in the fall and winter. Analyses of the data reveal distinct patterns in the soil solution for volatile fatty acids during soft tissue decomposition and for specific anions and cations once skeletonized, when based on accumulated degree days. Decompositional rates were also obtained, providing valuable information for estimating the "maximum time since death." Melanin concentrations observed in soil solution during this study also yields information directed at discerning racial affinities. Application of these data can significantly enhance "time since death" determinations currently in use.
